He wants to get better. You end up sometimes dragging him off the training ground because he wants to get better. It’s a massive plus in his favour,” he said.”Jack’s a football person. He will train all day and go and find a room somewhere and fall asleep. Then he’ll wake up and go and do a gym session, that’s how he is.”He’s that sort of character – I’m surprised his girlfriend is still with him! He’ll go back home and he’ll be watching football as well. He’s a football nut.”Jack and John McGinn were probably our most influential players last season and to expect them to be as influential in the Premier League is asking a little bit too much straightaway. But they are getting better and better, that’s for sure.”What we want Jack to do is to be running at opposition players and hurting them like he did against Crystal Palace.”

New Delhi: Rising domestic rice prices have affected exports this year with shipment of the non-Basmati variety falling about 37 per cent or 10 lakh tonnes, over the previous year. Though Basmati rice exports have also declined 1.5 per cent, but experts don’t suggest price as reason behind it. Arvind Kumar Gupta, Director of the Basmati Export Development Institution that comes under the Agricultural and Processed Food Products Export Development Authority (APEDA), told IANS, “Prices of non-Basmati rice are high in the country, which has affected its demand overseas. Exports have declined in the first four months of this financial year (FY20) against the corresponding period of FY19”. Also Read – Thermal coal import may surpass 200 MT this fiscal According to APEDA data, 17,06,891 tonnes of non-Basmati rice were exported in April-July of FY20 against 26,94,827 tonnes in the same period of FY19. The non-Basmati rice exports have declined around 9.88 lakh tonnes or 36.66 per cent. In value terms, it has declined by 36.30 per cent to Rs 48.16 crore over the smape period of FY19. Similarly, Basmati rice exports have declined by 1.42 lakh tonnes to 14.35 lakh tonnes between April and July against the year-ago period. Also Read – Food grain output seen at 140.57 mt in current fiscal on monsoon boost Vijay Setia, Chairman, All India Rice Exporters Association, said due to the high prices of non-Basmati rice its demand had soften in the foreign market. “The paddy is sold on the minimum support price (MSP) decided by the government, which pushes rates compared with other competitive countries”. Rise in local production in the importing countries is also the reason behind the falling demand. For instance, demand in Bangladesh has come down because of domestic production, said Setia. India is world’s top rice exporter, followed by Thailand and Vietnam. Pakistan also exports rice. “Countries, like Bangladesh, have to pay less shipping charges when they import rice from India. Therefore, high-prices don’t cost them much. But in the far away African countries, the situation is different. They purchase it from where they find it cheaper,” Gupta told IANS. There is a price difference of around $30 per tonne of non-Basmati rice between India and other nations. It meant that the domestic price was $30 per tonne higher, said Gupta.
Between his performances at the Funny Bone in Virginia Beach last weekend, Saturday Night Live alum Kevin Nealon hit the parking lot of PETA’s Norfolk headquarters, posing for photos, cracking jokes, and greeting families who brought dogs and cats to the group’s “SNIPmobile” clinic, which offers low- to no-cost sterilization and other veterinary services.Kevin Nealon At PETA’s Spay and Neuter ClinicCredit/Copyright: PETA“Nobody would trust me to neuter their dog, and nobody should — so it’s a good thing that PETA’s got veterinarians to do it,” says Nealon. “It’s not rocket science: Every homeless puppy and kitten was born to parents who weren’t spayed or neutered. I’m proud to support PETA’s work to prevent animal homelessness.”“Kevin is always willing to lend a hand to help animals, and that includes taking time out to spread the word that a ‘snip’ in time saves nine—or 9,000,” says PETA Vice President Daphna Nachminovitch. “The way to fix the homeless animal overpopulation crisis is by ‘fixing’ dogs and cats, and PETA’s SNIP clinics do the job.”Six to 8 million homeless dogs and cats end up in animal shelters every year, and half of them must be euthanized because there simply aren’t enough good homes for them. Others never make it to a safe haven and are abandoned to fend for themselves on the streets. The only effective, long-term solution is spaying and neutering—and PETA’s mobile clinics have “fixed” nearly 94,000 animals in just the last decade.For more photos from the event, click here.
Before any MLB playoff games were played, things were looking so good for Canada’s World Series hopes. (The country’s title drought in hockey gets all the attention, but no baseball champ has hailed from north of the border since 1993, either.) With odds of 19 percent, the Toronto Blue Jays had the best chance of winning the World Series of any team, according to our pre-playoffs MLB Elo ratings.Now? Not so much. The Blue Jays have lost the two first games to the Texas Rangers in their best-of-five American League Division Series. That’s changed their chance of winning it all — as well as everyone else’s.According to the latest Elo simulation of the rest of the playoffs — which includes the Rangers’ victory over Toronto on Friday afternoon but no subsequent results — the Blue Jays’ probability of breaking Canada’s winless streak is now just 5 percent: CHANCE THAT A TEAM WILL … Toronto Blue Jays15641001585 Los Angeles Dodgers1535100522411 New York Yankees15160000 TEAMELOMAKE LDSMAKE LCSMAKE WSWIN WS Kansas City Royals1538100331810 St. Louis Cardinals1549100502814 Texas Rangers1535100%85%43%22% New York Mets1523100482110 Pittsburgh Pirates15540000 Because they’re up 2-0 in their series versus Toronto, the Texas Rangers are now your World Series favorites, though that can and will change depending on what happens the rest of Friday.

State Rep. Triston Cole, R-Mancelona, today introduced legislation that will remove unnecessary regulations for morel mushroom enthusiasts to obtain a mandatory certification to be able to pick and sell morels to local businesses.House Bill 5532 will remove morel mushrooms from the food code that requires harvesters to be certified to sell.“Finding, picking and selling morel mushrooms is a favorite northern Michigan activity,” Rep. Cole said. “The 105th House District hosts two festivals a year, one in Boyne Falls (54th Annual Morel Festival in Boyne City will be held May 12-15, 2016.) and one in Lewiston (Lewiston’s Annual Morel Mushroom Festival & Spring Craft Show Saturday, May 7th, 2016) dedicated to morel mushrooms. Tourists flock to the very rural areas of northern Michigan to hunt for morel mushrooms. This brings a great deal of revenue to my district.”“I can still remember as a kid going mushroom hunting and selling buckets of morels to local restaurants. Under our state’s current law the government has made this an illegal practice. The commonality and unique identification of morel mushrooms make them ideal for exemption to this burdensome regulation and a mandatory certification course that costs participants $175 per class.”HB 5532 has been referred to the House Agriculture Committee.

Cannabis Industry Likely to Employ More Than 400,000 By 2021, Study Projects Next Article Guest Writer Cannabis The federal government shows few signs it will legalize one of the biggest job producers in the country. dispensaries.com Opinions expressed by Entrepreneur contributors are their own. Listen Now Image credit: Heath Korvola | Getty Images Green Entrepreneur Podcast –shares When it comes to projections, no sector of the economy currently has a rosier outlook than the marijuana industry.The latest report from ArcView Market Research demonstrates how big the numbers are getting. The name of the report neatly sums up the optimism of its findings: “U.S. Legal Cannabis: Driving $40 Billion Economic Output.”No one is questioning the potential for growth in the industry. Entrepreneurs have flocked to cannabis because of that potential. But there are headwinds, mostly involving an anti-marijuana U.S. attorney general, a White House administration that has largely stayed quiet on the issue and difficulties getting marijuana markets set up in some places even where voters have approved it.Still, in a release on the new report, ArcView CEO Troy Drayton said the economic potential of legal cannabis “is no longer just theory. Due to the giant impact adult-use legalization is already having in the United States, it’s vital for key stakeholders to understand the full impact of legalization, beyond just retail sales numbers.”So, what did the report find that impact would be?Related: Despite Being Illegal Under Federal Law, Cannabis Has Grown Into a $9 Billion Industry In States Where It Is Legal.California ImpactThe report was done against this backdrop: More than half of all U.S. states have approved a legal medical marijuana market, with adult-use marijuana sales are in place in Alaska, Colorado, Nevada, Oregon and Washington.California also started adult-use sales in January. Massachusetts is expected to start later this year. Lawmakers in Maine are still trying to work out a deal to get their adult-use market up and running, while New Jersey’s new Democrat governor has pledged to legalize marijuana in the Garden State.But California is the driver behind many positive projections. The biggest state in the union, California is expected to add billions to the marijuana market in the U.S.ArcView, which did the study with cannabis business intelligence company BDS Analytics, projects the marijuana industry in the U.S. will account for $39.6 billion in economic output by 2021. About 60 percent of that will come from just six states: California, Colorado, Massachusetts, Nevada, Oregon and Washington.The Golden State also is projected as a huge factor in another area: cannabis jobs.Related: Study Suggests Legal Pot Would Make Border Safer Than a Massive WallCannabis WorkersThe report projects that the California cannabis industry will add 99,000 jobs by 2021, about a third of all the cannabis-related jobs in the U.S. Indirect jobs related to the cannabis industry will total about 146,000 in the state.Other projections and findings from the report:The cannabis industry will create 414,000 jobs across the country by 2021, either directly in the cannabis industry or in a related job.State and local governments are projected to reap $4 billion in total tax receipts from the marijuana industry by 2021.The report argues that the legal recreational marijuana industry in Colorado may have led to the state having one of the lowest unemployment rates in the country.The total amount of taxes taken in by states where cannabis is legal reached $1 billion in 2016, including wholesale, excise and cannabis-specific sales taxes.Clearly, those numbers are a business person’s dream (government officials, too). The growing economic power of the legal marijuana industry might be the one thing that keeps it from coming under attack by the current administration in Washington.To stay up to date on the latest marijuana related news make sure to like dispensaries.com on Facebook February 15, 2018 3 min read Each week hear inspiring stories of business owners who have taken the cannabis challenge and are now navigating the exciting but unpredictable Green Rush.

Ashley Madison wants its users back.Sure, there was an embarrassing data breach last year. Sure, it wreaked embarrassment and devastation across its own user base. And sure there was the little matter of men paying subscription fees to talk with what turned out to be chat bots due to a startlingly low number of women users on the site. But that’s all water under the bridge. They’ve changed — transformed, even. And like any cheater worth his or her salt, the site is looking for a second chance.So it’s out with the old slogan — “life is short, have an affair” — and in with a new, risqué ad campaign.Is Ashley Madison’s new ad about hooking up at a hotel enough to restore people’s trust? https://t.co/4syldGRVgN— Entrepreneur (@Entrepreneur) July 12, 2016Related: Hackers Release the Personal Information of Adultery Seekers Who Joined Ashley MadisonIn one, a work-weary woman with a ho-hum other half ships off to a conference — only to bump into an interesting stranger.In another, a clock watcher with a terrible apartment and a worse shirt finds a rare ray of sunlight — a woman who smiles at him in the subway.And, in a third, a couple who seem polite, not passionate, meet an intriguing woman at a party.At the end of each of these inaugural ads for TV, Ashley Madison compels viewers to “Find Your Moment.” As before, cheating is a form of exploration. A sort of adventure. Don’t you want to seize the day? Ashley Madison certainly hopes so. The 47 million-member extramarital affair online hub took a deep, dark hit to its already controversial brand during last year’s hack and it’s still reeling from the damage. Key to its rebound isn’t just demand for affairs — but building back trust with users.Related: Court Rules FTC Can Come After Your Company After a Cyber AttackCuriously, Ashley Madison’s own ads remind users that cheaters don’t often need much help cheating. Every character in the company’s own ads finds new romantic friends in the usual spots — at hotels, parties and out and about. These folks don’t need the help of a digital platform that exposed millions of users, from pastors to government employees to low-level celebs. They did it on their own. DIY-style.Ashley Madison is hoping you won’t make that observation — and that its users can forget the past. So, what do you think? Will its seamy new TV spots be enough to restore trust in a platform built on breaking trust?

Next Article We Didn’t Put a Woman in the White House. But What About Women in the Workplace? Image credit: Harper Collins Opinions expressed by Entrepreneur contributors are their own. –shares Women Leaders Joann S. Lublin November 9, 2016 9 min read Editor’s Note: On this day following the presidential election of 2016, many Americans are just starting to parse the pro and con messages about women that emerged from the two campaigns: One, the glass ceiling didn’t get broken, after all. And, two, how are women (and their men supporters) to think about the misogynistic talk that occurred in this election?Related: Sheryl Sandberg, Lean In 2.0 and Corporate Gender BiasGiven that reality, it’s perhaps especially appropriate today to feature an excerpt from the new book Earning It: Hard-Won Lessons from Trailblazing Women at the Top of the Business World, by Joann S. Lublin, a Pulitzer Prize-winning journalist and management news editor for The Wall Street Journal. Among the first female reporters at The Journal, Lublin faced uphill battles in her career, to become deputy bureau chief of the newspaper’s important London bureau, the first time it had been run by a woman. For her book, Lublin interviewed more than 50 women who had reached the highest rungs of the corporate ladder — across a diversity of industries, including retail, manufacturing, finance, high technology, publishing, advertising, automotive and pharmaceutical.Here is an excerpt from the chapter “Male Mentors Mean Business,” applicable to women in all workplaces, large or small . . .Countless women have seen their careers soar, thanks to help from a powerful senior executive. But some women paid a price for their close relationship with a male mentor. One such woman was Melissa Dyrdahl, the [former] chief executive of Ella Health, a health care start-up for women. She saw her career take off after Bruce R. Chizen, a former boss, hired her in 1994 to join Adobe Systems, the software maker, as a senior marketing manager. The two had developed a strong rapport at Claris, their former employer, and Dyrdahl assisted him in running a small new division of Adobe.“He knew exactly what he was getting from an employee standpoint,” Dyrdahl remembered. Chizen became her unofficial career coach at Adobe, offering insights about ways to excel in the male-dominated technology industry. Having a boss as a mentor helped Dyrdahl to get the respect she felt that she deserved, she said when we spoke. She saw that when professional challenges arose, Chizen and other senior Adobe men “always came in with an answer.”Because the two knew each other so well, “I’m brutally honest with her,” Chizen said in a Wall Street Journal article that I wrote about executive mentors. He also acted as Dyrdahl’s sponsor, an influential individual who opens the door of a promotion elevator and pushes a protégé through. During his climb to top management at Adobe, he brought along Dyrdahl and other valued mem-bers of his team. “I had someone who was highly respected, a more senior leader, making sure my name got put on the table,” Dyrdahl told me. With Chizen’s support, Adobe appointed her global vice president of marketing in 1998 and then advanced her to a senior vice presidency before elevating Chizen from president to CEO in late 2000. Once they both had reached the executive suite, Chizen and Dyrdahl occasionally drove to and from Adobe headquarters in San Jose together because they and their spouses lived near each other in suburban Los Altos. “We socialized together,” Dyrdahl recalled. “I know his kids. My husband has remodeled their house.” But as a result of these ties, the two high-profile executives encountered unexpected repercussions. One day, a human resources staffer at Adobe who was friends with Chizen and Dyrdahl strode into her office. “I just need to tell you, because nobody is going to tell you,” she said. “There’s people who think there’s something going on with you and Bruce.”The office gossip shocked Dyrdahl. Her jaw dropped, and “I was reeling,” she recollected. It suddenly dawned on her that she and Chizen now occupied a much more visible stage at the office. She quickly assured the human resources staffer that their relation-ship was purely professional. “I don’t want people to think I slept my way to the top,” Dyrdahl told her HR colleague.Driving home with Chizen soon after, Dyrdahl told him that coworkers wrongly perceived him as being something more than her supervisor and mentor. “They are only going to think badly of me,” she said. “Lots of things that we take for granted and we don’t think twice about, I can’t do anymore.”Chizen understood and accepted dramatic adjustments. They stopped driving together or going out for drinks unless a third person was present. “[I] never sat next to him in a meeting again,” Dyrdahl said. “I told him, ‘Unless there is no other chair, do not sit next to me.’”Even today, suspicions about an illicit affair sometimes arise when a male executive mentors or sponsors a female subordi-nate. For this reason, most senior-level men hesitate “to have one-on-one contact with a potential protégé who happened to be a younger woman,” said Sylvia Ann Hewlett in her 2013 book, (Forget a Mentor) Find a Sponsor: The New Way to Fast-Track Your Career. Her observations reflected research by the Center for Talent Innovation, a New York think tank that she heads and that studies issues in the workplace.This reluctance, Hewlett wrote, explains “why men are so much more likely to sponsor other men, inadvertently perpetuating the old boys’ club.” A 2010 study by her think tank found that men are 46 percent more likely to have sponsors than women. “Up-and-coming females tend to conclude that sponsorship, sexually fraught as it might be, is something they don’t actually need,” she said in her book.Hewlett considers that a dangerous assumption. Mentors build a woman’s self-esteem and serve as an empathetic sounding board, but sponsors expend valuable chips on a woman’s behalf and provide air cover so she can take risks. “Sponsors, not mentors, put you on the path to power and influence by affecting three things: pay raises, high-profile assignments, and promotions,” she wrote.Other researchers support Hewlett’s argument. More than half of senior executive women said having a higher-level sponsor is extremely important, yet women have less access to senior male staffers who could assist with their careers, concluded a 2015 study by LeanIn.Org, founded by Sheryl Sandberg, and McKinsey. The research tracked women’s progress at 118 North American companies. A handful of corporate programs designate workplace advocates for managerial women. At least nine big businesses have set up sponsorship initiatives that match promising female leaders with sponsors or teach such women how to attract a sponsor, I wrote in an advice column on careers published on WSJ.com in 2011. American Express Co., for example, launched its “Pathways to Sponsorship” program that year for twenty-one female senior vice presidents at the major financial services company. By the end of 2014, 25 percent of those initial participants had been promoted and 45 percent had made strategic lateral moves, an American Express spokeswoman told me. The company has also expanded its sponsorship effort to cover a wider range of managerial levels.Yet formal mentoring and sponsorship programs remain far out of reach for most professional women. Only 30 percent of all American professionals have access to such programs, and there is a smaller proportion of women than men within that group, according to a 2014 survey of 1,005 adults by Edward Jones, a financial services firm. Just 18 percent of the women allowed to participate in these programs actually do, the poll showed, compared with 21 percent of the men.Men on Women’s SideMale mentors and sponsors played crucial parts in the careers of numerous corporate executives I interviewed. “At the end of the day, men still hold most of the power,” suggested Sandra “Sandi” Peterson, the group worldwide chairman of Johnson & Johnson. “So you better have male mentors.”But as is evident from Dyrdahl’s experience, women must make sure that their relationships with higher-level men don’t raise eyebrows among coworkers. To further refute false rumors about any romantic entanglement with Chizen, she stopped her habit of flying alone with him on commercial flights for business travel.In Dyrdahl’s view, things haven’t improved for women since she left Adobe in late 2006. These days, she encourages women to take steps that clarify their ties with a male mentor so the relationship cannot be misconstrued by colleagues. “You give up your power when you wittingly or unwittingly put yourself in situations where people perceive you as having an affair and getting something because of your sex,” she pointed out. “I felt I had to work twice as hard because I was blond and attractive.”Related: For Women in Tech, Bias Runs Deeper Than Most Think Management News Editor, The Wall Street Journal Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right.

Reviewed by Alina Shrourou, B.Sc. (Editor)Dec 4 2018In a small study of infrequent cannabis users, Johns Hopkins Medicine researchers have shown that, compared with smoking cannabis, vaping it increased the rate of short-term anxiety, paranoia, memory loss and distraction when doses were the same.The findings of the new study, described in the Nov. 30 edition of JAMA Network Open, highlight the importance of dose considerations with the perception that vaping is a safer alternative to smoking cannabis, the researchers say. And they ask regulators of medical and recreational cannabis dispensaries to take note.Vaping devices heat cannabis to a temperature in which the mind-altering compounds in the plant are released as a vapor that is inhaled. Vaping is thought to be safer for cannabis and tobacco use because it doesn’t produce many of the harmful components of burning material such as tar and other cancer-causing agents.But, the researchers say, their study suggests that at least for first-timers or others who don’t use cannabis regularly, vaping delivers greater amounts of THC, the primary intoxicant in cannabis, which increases the likelihood of adverse reactions.”In light of increased legalization of cannabis, we designed our study to be more representative of the general population’s exposure to cannabis, namely someone who has never smoked it and wants to try it for medical or recreational purposes, or someone who does not use it regularly enough to understand or predict its effects,” says Ryan Vandrey, Ph.D., associate professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine. “What our study suggests is that some people who use cannabis infrequently need to be careful about how much cannabis they use with a vaporizer, and they should not drive, even within several hours after use. It could be dangerous for themselves and others, and on top of that, they may experience negative effects such as anxiety, nausea, vomiting and even hallucinations,” he adds.For their study, the researchers chose 17 volunteer participants (nine men and eight women, average age 27 years), who hadn’t used cannabis in the past 30 days, which was verified by a drug screen, and together on average hadn’t used in over a year.In a controlled setting at Johns Hopkins Bayview Medical Center’s behavioral pharmacology research unit, each participant either smoked or vaped cannabis containing 0, 10 or 25 milligrams of Δ9-tetrahydrocannabinol (THC), the active component in cannabis that gives people the high, in single visits once a week over six weeks. The researchers say that 25 milligrams of THC is a relatively low dose, and much less than is typically found in pre-rolled cannabis “joints” sold in dispensaries where cannabis is legal. The participants either smoked preloaded pipes or inhaled vapor from a vaporizer. Neither the participants nor the researchers knew the doses of THC that were delivered in a given experimental test session.During each of the six sessions, the research team observed and assessed drug effects in the test subjects, including for adverse reactions. They also measured vital signs such as heart rate and blood pressure and collected blood samples just after smoking, every 30 minutes for two hours and then every hour for eight hours.Each participant also completed the Drug Effect Questionnaire–rating self-reported drug effects out of a score of 100–shortly after smoking and each hour for up to eight hours later. The survey assessed overall drug effect; feeling sick, anxious, hungry, sleepy and restless; and experiencing heart racing, dry mouth, dry eyes, memory impairment and coughing.Results showed that a few minutes after smoking, those who vaped the 25-milligram THC dosage reported an average of 77.5 on the overall strength of the drug’s effect, meaning how high they felt compared with the average score of 66.4 reported by those who smoked the same dose. Participants who vaped 25 milligrams of THC reported about a 7 percent higher score on average for anxiety and paranoia, compared with people who smoked the same amount of the compound. Those who vaped any dose of THC also reported higher levels of dry mouth and dry eyes than those who smoked it. For example, when vaping 25 milligrams of THC, the participants rated dry mouth at 67.1 on average compared with 42.6 for those smoking it.Related StoriesNew study shows clear link between cannabis use and brain alterationsStudy: Less than 50% of U.S. adults exposed to court-ordered anti-smoking advertisementsCannabis use during pregnancy may cause premature birthResearchers say the participants also completed three computerized tasks designed to measure attention span, memory, physical reaction time and motor movement. One task required the participant to replicate the shape of patterns, another required them to add up strings of single-digit numbers and the third required them to follow a dot across the screen with the cursor while also tracking a dot that pops up in the periphery.The tests are meant to represent skills needed for proper workplace performance, operating a car or other daily activities. Reaction times on average were slower by more than 120 milliseconds with both active test doses of THC, using either smoking or vaping, when compared with reaction time after smoking or vaping cannabis without any THC.Next, the researchers compared the effects of vaping compared with smoking on participants taking the computerized Divided Attention Task, which required participants to track a square on the computer screen while also monitoring numbers in each corner of the screen. The amount of time participants accurately tracked the square on the computer in the Divided Attention Task dropped by an average of 170 percent after smoking 25 milligrams of THC compared with the cannabis without THC.The amount of time they accurately tracked fell an average of 350 percent when vaping 10 milligrams of THC and fell 500 percent when vaping 25 milligrams of THC, compared with those smoking either dose.”Our participants had substantially higher impairment on the tasks when vaping versus smoking the same dose, which in the real world translates to more functional impairment when driving or performing everyday tasks,” says postdoctoral fellow Tory Spindle, Ph.D., a researcher in the behavioral pharmacology research unit at Johns Hopkins Bayview.Other results showed that blood levels of THC were at their highest immediately after smoking or vaping cannabis. At 10 milligrams of THC, blood levels of THC reached an average of 7.5 nanograms per milliliter in vapers, compared with 3.8 nanograms per milliliter in smokers 10 minutes after they inhaled the drug. At 25 milligrams of THC, blood levels reached an average of 14.4 nanograms per milliliter when vaped compared with 10.2 nanograms per milliliter when smoked.”There’s a definite differences in the amount of drug making it into the blood when using a vaporizer versus smoking the drug, so considerations need to be made when dosing to ensure people are using cannabis safely,” says Spindle.The researchers note that they could only detect THC in the blood samples up to four hours after using, even though the participants reported the drug’s effects lasted five or six hours. The researchers say this suggests that blood testing isn’t an accurate way to tell if someone is high or perhaps driving under the influence.Two participants vomited after vaping 25 milligrams of THC, and another experienced hallucinations. One person vomited after smoking 25 milligrams of THC.Vandrey cautions that the study involved only a small number of younger adults and lasted only six weeks. “We still don’t have a full look at the long-term effects of vaping, such as whether there is a risk for chronic bronchitis, and more work needs to be done on that front,” he says. It is important to note that these effects were observed in individuals who don’t use cannabis very often, and may not extend to people who use cannabis routinely; they may have developed tolerance to these effects and also may be better able to regulate their dose.In recent years, Canada and several U.S. states including Washington, California, Colorado and Massachusetts have legalized cannabis for recreational use. Thirty-two states have made cannabis available with a doctor’s prescription, including Maryland, where the research was performed.Source: https://www.hopkinsmedicine.org/news/newsroom/news-releases/vaping-cannabis-produces-stronger-effects-than-smoking-cannabis-for-infrequent-users

In 2015, adolescents ages 16-18 contributed approximately 1.5 million blood donations.Although blood donation is largely a safe procedure, adolescents are at a higher risk for acute, adverse donation-related problems, such as injuries from fainting during donation, explains study leaders Eshan Patel, M.P.H., a biostatistician in the Department of Pathology at the Johns Hopkins University School of Medicine, and Aaron Tobian, M.D., Ph.D., professor of pathology, medicine, oncology and epidemiology at the Johns Hopkins University School of Medicine and director of transfusion medicine at The Johns Hopkins Hospital.Additionally, they add, blood donation may also increase the risk of iron deficiency, as each whole blood donation removes about 200-250 milligrams of iron from the blood donor. Because adolescents typically have lower blood volumes, when donating the same amount of blood, they have a relatively higher proportional loss of hemoglobin–the iron-containing protein in blood cells that transports oxygen–and consequently more iron during donation than adults. Females are even more at risk of iron deficiency than males due to blood loss during menstruation every month.Numerous studies have shown that younger age, female sex and increased frequency of blood donation are all associated with lower serum ferritin levels (a surrogate for total body iron levels) in blood donor populations. However, note Patel and Tobian, no study using nationally representative data has compared the prevalence of iron deficiency and associated anemia between blood donor and nondonor populations, specifically adolescents.Related StoriesCancer patients and those with anemia should not be denied opioids, says CDCInnovative microfluidic device simplifies study of blood cells, opens new organ-on-chip possibilitiesDon’t Miss the Blood-Brain Barrier Drug Delivery (B3DD) Summit this AugustToward this end, the researchers analyzed data from the National Health and Nutrition Examination Survey, a long-running study designed to assess the health and nutritional status of adults and children in the U.S. based on both physical exams and interviews conducted by the Centers for Disease Control and Prevention. From 1999 to 2010, this study included collections of blood samples as well as questions about blood donation history in the past 12 months.The researchers found 9,647 female participants 16-49 years old who had provided both samples and blood donor history information. There were 2,419 adolescents ages 16-19 in this group.They report in the journal Transfusion on Feb. 19 that about 10.7 percent of the adolescents had donated blood within the past 12 months, compared with about 6.4 percent of the adults. Mean serum ferritin levels were significantly lower among blood donors than among nondonors in both the adolescent (21.2 vs. 31.4 nanograms per milliliter) and the adult (26.2 vs. 43.7 nanograms per milliliter) populations. The prevalence of iron deficiency anemia was 9.5 percent among adolescent donors and 7.9 percent among adult donors–both low numbers, but still significantly higher than that of nondonors in both age groups, which was 6.1 percent. Besides, 22.6 percent of adolescent donors and 18.3 percent of adult donors had absent iron stores.Collectively, the authors say, these findings highlight the vulnerability of adolescent blood donors to associated iron deficiency.Patel and Tobian note that some federal policies and regulations are already in place to protect donors in general from iron deficiency due to this altruistic act, such as hemoglobin screening, a minimum weight to donate and an eight-week interval between donations for repeat whole blood donation. However, more protections are necessary for adolescent donors–for example, suggesting oral iron supplementation, increasing the minimum time interval between donations or donating other blood products such as platelets or plasma rather than whole blood could help mitigate iron loss.”We’re not saying that eligible donors shouldn’t donate. There are already issues with the lack of blood supply,” Tobian says. “However, new regulations or accreditation standards could help make blood donation even safer for young donors.” Reviewed by James Ives, M.Psych. (Editor)Feb 19 2019New public health measures could help protect this vulnerable population, authors sayFemale adolescent blood donors are more likely to have low iron stores and iron deficiency anemia than adult female blood donors and nondonors, which could have significant negative consequences on their developing brains, a new study led by Johns Hopkins researchers suggests. Based on these findings, the authors propose a variety of measures that could help this vulnerable population.
Reviewed by Alina Shrourou, B.Sc. (Editor)May 7 2019Lung transplantation, the only lifesaving therapy for an increasing population of patients with end-stage lung disease, is severely limited by the number of available donor organs. Currently, up to 80 percent of donor lungs are rejected for serious but potentially reversible injuries. Since the beginning of transplantation in the 1960s, clinicians and scientists have been trying to address the critical shortage of donor organs.Now, a multidisciplinary team from Columbia Engineering and Vanderbilt University has–for the first time–demonstrated in a clinically relevant model that severely damaged lungs can be regenerated to meet transplantation criteria. In a study published today on Nature Communications ‘ website, the researchers describe the cross-circulation platform that maintained the viability and function of the donor lung and the stability of the recipient for 36 to 56 hours. As Brandon Guenthart, a lead author of the study, explains, “to support lung recovery and to demonstrate cellular regeneration, we had to pursue a radically different approach and develop more minimally invasive diagnostics.” Current methodologies of lung support are limited to only 6 to 8 hours, a time that is too short for therapeutic interventions that could regenerate the injured lung and improve its function.The team, co-led by Gordana Vunjak-Novakovic, University Professor and The Mikati Foundation Professor of Biomedical Engineering and Medical Sciences at Columbia Engineering, and Matthew Bacchettaunjak-Novakovic, the H. William Scott Professor of Surgery at Vanderbilt University, and adjunct professor at Columbia’s department of biomedical engineering, also developed new diagnostic tools for the non-invasive evaluation of the regenerating lung. They expect their advance will lead to an increase in the number of lungs for transplant, through the recovery of severely damaged lungs that are currently unsuitable for clinical use.The researchers have long been focused on developing processes to recover lungs that are being turned down for transplant because of injury to enable people with end-stage lung disease to live longer and better lives. “We have been fortunate to assemble a highly talented, interdisciplinary team of bioengineers, surgeons, pulmonologists, and pathologists, who have designed a durable physiologic support system for a donor lung outside the body, along with new technologies to achieve and monitor lung recovery,” Bacchetta says.Related StoriesVortex flow closely linked to pressure differences in ventricles of the heartComprehensive gene activity database could significantly reduce animal useUranium toxicity might have caused obesity and diabetes in Kuwait, finds new studyA previous study from the team demonstrated a cross-circulation platform that maintained the viability and function of a donor lung for 36 hours. The researchers were able to use their advanced support system to fully recover the functionality of lungs injured by ischemia (restricted blood supply) and make them suitable for transplant.For this new study, the team decided to test the effectiveness of their platform technology combined with conventional therapies and new diagnostics on lungs afflicted by the most frequent injury leading to donor lung rejection–gastric aspiration. This injury is caused by the entry of gastric material into the respiratory tract, resulting in severe injury to the pulmonary epithelium and thus making the lung unacceptable for transplantation. Currently, severely damaged donor lungs cannot be salvaged using existing devices or methods. This new study suggests that lungs injured by gastric aspiration can be maintained outside the body for several days, are amenable to repeated therapeutic interventions, and display evidence of cellular regeneration and improved function. Lungs regenerated on this platform met all criteria for transplantation.”For seven years, we have diligently worked to develop new technologies for the maintenance and recovery of donor organs. This paper represents a culmination of fundamental and translational studies of lung bioengineering that have converged into a system capable to recover severely damaged lungs. We now have the team and technology to bring this research to the patients, by making more donor lungs available for transplant,” says Vunjak-Novakovic.The team plans to conduct further studies to evaluate the functional capacity of the lungs following transplantation and the safety of the method, using a clinically relevant large animal model with immunosuppression.”We envision that interventional cross-circulation may be used to investigate regeneration of other damaged organs, such as hearts, kidneys, and livers, expanding donor pools by salvaging severely damaged organs and leading to more organ transplants,” Bacchetta adds.

Much of the research led by CD4 director Pia Vogel and Wise is centered on a class of proteins called ABC transporters, a key factor in why many cancers resist chemotherapy.”These transporters are defensive proteins and are normally very, very good for us. They protect us from toxic chemicals by literally pumping them out of the cell, almost like a sump pump removes water from one’s cellar,” Vogel said.But when someone has cancer, these proteins do more harm than good.”One protein, P-glycoprotein, can pump nearly all chemotherapeutics out of the cancer cell, thereby making the cancer resistant to many drugs and untreatable,” Wise noted.For this reason, SMU researchers tested the combination of using an inhibitor that temporarily shuts down P-glycoprotein’s ability to remove drugs from the cancer cells along with chemotherapeutics on prostate cancer cells grown in the lab, which have been shown to be resistant to multiple chemotherapeutic drugs.Related StoriesLiving with advanced breast cancerVirus killing protein could be the real antiviral hero finds studyNew study to ease plight of patients with advanced cancerThe SMU team was able to show that if inhibitors of P-glycoprotein are used during and after the multidrug resistant cancer cells have been exposed to the chemotherapy drugs, then the cancer cells become much more sensitive to the chemotherapeutics.The recipe for success was giving cancer cells a dose of both chemotherapy drugs and the P-gp inhibitor for just two hours. Researchers then washed the prostate cancer cells to get rid of any residual chemotherapy drugs before giving the cells another dose of just P-gp inhibitor for 22 hours, lead author and SMU Ph.D. doctoral candidate Amila K. Nanayakkara explained.Prostate cancer cells that were given this treatment were shown to retain chemotherapy drugs at a much higher level compared to cancer cells not treated with the P-glycoprotein inhibitor. After about 24 hours, much fewer of these cancer cells survived in this treatment compared to the cells which had not seen the inhibitor.When the same tests were performed on normal noncancerous cells, “there was no sign of extra toxicity to the healthy cells using this method,” Wise added.One issue, though, is how to duplicate this method in a patient’s body. “Once you’ve taken a chemotherapy drug, it’s not easy to remove it after just two hours,” said co-author Vogel, a professor in the SMU Department of Biological Sciences.Still, the researchers argued that it is worth further research, because there are currently few options for cancer patients once their disease becomes resistant to multiple chemotherapies.”Our paper shows these remarkable effects when the inhibitor is present during, and importantly, after exposure to chemotherapeutic,” Wise said. “And while ‘washing’ is not feasible in humans, the kidneys and other organs are in a sense doing the washing step for a patient. These organs are washing the chemotherapy from the bloodstream and therefore, out of cancer cells. So in that way, we think our preliminary cell culture studies may be translatable at least in principle to animals and people.” Reviewed by James Ives, M.Psych. (Editor)Jun 10 2019Researchers at SMU’s Center for Drug Discovery, Design and Delivery (CD4) have succeeded in lab testing the use of chemotherapy with a specific protein inhibitor so that the chemotherapeutic is better absorbed by drug-resistant cancer cells without harming healthy cells. The approach could pave the way for a more effective way to treat cancers that are resistant to treatment.A mix of drugs is frequently used to shrink cancer tumors or keep tumor cells from spreading to other parts of the body. But chemotherapy is so toxic that the mix often kills healthy cells, too, causing dreadful side effects for cancer patients. And eventually, many cancers learn how to resist chemotherapy, making it less effective over time. When multidrug resistance evolves, this leaves the patient with a very poor prognosis for survival and the oncologist with few, if any, effective tools, such as chemotherapy medicines, to treat what is very likely an aggressive and/or metastatic cancer at this point.”John Wise, associate professor in the SMU Department of Biological Sciences and co-author of a study on the findings published in PLOS ONE Source:Southern Methodist University

Crash marks first death involving fully autonomous vehicle The deadly collision between an Uber autonomous vehicle and a pedestrian near Phoenix is bringing calls for tougher self-driving regulations. But advocates for a hands-off approach say big changes aren’t needed. Police in Tempe, Arizona, say the female pedestrian walked in front of the Uber SUV Sunday night. Neither the automated system nor the human backup driver stopped in time. Local authorities haven’t determined fault.Current federal regulations have few requirements specifically for self-driving vehicles, leaving it for states to handle. Many, such as Arizona, Nevada and Michigan, cede key decisions to companies.Many federal and state officials say their regulations are sufficient to keep people safe while allowing the potentially life-saving technology to grow.

According to Shamunder, “There should be potential for it to be monetizable, but every idea doesn’t have to be like that. It can be something that can be used to solve some unique societal problem as well.”Verizon claims it is motivated by the concept of generating such ideas and not because of any of the extra marketing attention the challenge brings to its 5G as it launches these networks at the same time that rivals such as AT&T, T-Mobile and Sprint do.Shamunder concedes that the marketing aspect is a “byproduct,” but hardly the main purpose.”We don’t have a monopoly on ideas,” she says. “There are people out there who have deep insight into certain industries and that have their own unique problems. We have these toolboxes we want them to use to solve these problems and they are better at doing that than I am.”The various legal and other requirements that are part of the challenge are still being hammered out and will be posted on a Verizon website; it is probably safe to assume that Verizon will retain first right of refusal over any idea that is selected.It is unclear what kind of ownership stake Verizon will take in any of the winning ideas.This isn’t, in fact, the first time Verizon has challenged outsiders to develop ideas for 5G. In partnership with Ericsson and the Mass Tech Leadership Council, Verizon in November announced the launch of the Verizon 5G Robotics Challenge for universities, startups, and other developers in the greater Boston area to create 5G-powered robotics technologies that will transform modern industry. The pool money in that challenge was $300,000. Winners have not yet been selected. It has issued another similar challenge geared toward first responders.Verizon describes its far broader latest challenge as “a nationwide search for the biggest and brightest ideas that will bring the true power of 5G to life. Winners will be judged on innovation, commercial viability, and the potential impact and sustainability of how their ideas will be able to make the world a better, more connected place.”Judging will begin in the spring.

If Verizon buys into in your vision and considers it commercially viable, the company will issue you up to a cool $1 million in seed money. What’s more, you’ll be invited to develop the concept on live networks in one of Verizon’s 5G incubator labs, in New York City; Cambridge, Massachusetts; Los Angeles; Palo Alto, California, and Washington, D.C. And Verizon will provide training and technical support to the chosen innovators.It’s all part of a “Built on 5G Challenge” launched this week at CES in Las Vegas during a keynote address by Verizon CEO Hans Vestberg.5G is all about blistering speeds and low latency or network responsiveness, but the promise behind the technology extends well beyond the wicked fast handset you hope to carry in your pocket. There’s surely no small amount of hype around 5G, with Verizon referring to it as the “fourth industrial revolution.” The tech is meant to play an important role in self-driving cars, remote medicine, immersive education and all things connected, whether in your home, business or entire “smart community.”How might you play a small part in the revolution? Verizon’s challenge is open to venture-funded companies, bootstrapped startups, non-profits, educators, and yes, creative individuals. The $1 million that the company promises to dish out represents a pool of money that will be shared among a limited selection of potential winners; no more than two or three seems likely. If you’re the only one you could get the full million.Not just a PowerPointApplicants must meet certain criteria, says Sanyogita Shamunder, a network vice president for 5G ecosystems and innovation at Verizon. Is what you’ve cooked up real? What capabilities does the idea use? Can it realistically be implemented, given the current state of artificial intelligence, available hardware or other technologies? And does it really require 5G?”It can’t be just a PowerPoint. There needs to be a proof of concept,” Shamunder says.It’s too soon to tell, she adds, whether chosen ideas will turn into actual commercial products. Verizon could acquire the winning company behind an innovative idea—or not. It could license some aspect of the technology—or not. Citation: Edward C. Baig: Have a great idea for 5G?

On July 20, 1969, an estimated 650 million people watched in suspense as Neil Armstrong descended a ladder towards the surface of the Moon. As he took his first steps, he uttered words that would be written into history books for generations to come: “That’s one small step for man. One giant leap for mankind.” Or at least that’s how the media reported his words.These Sharks Were Too Busy to Notice a Bigger Predator Watching ThemThe unexpected twist at the end of this feeding frenzy delighted scientists.Credit: NOAA Office of Ocean Exploration and Research, Windows to the Deep 2019Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Headbutting Tiny Worms Are Really, Really Loud00:35关闭选项Automated Captions – en-US facebook twitter 发邮件 reddit 链接https://www.livescience.com/65950-neil-armstrong-first-words-on-moon.html?jwsource=cl已复制直播00:0002:2802:28 But Armstrong insisted that he actually said, “That’s one small step for a man.” In fact, in the official transcript of the Moon landing mission, NASA transcribes the quote as “that’s one small step for (a) man.” As a linguist, I’m fascinated by mistakes between what people say and what people hear. In fact, I recently conducted a study on ambiguous speech, using Armstrong’s famous quote to try to figure out why and how we successfully understand speech most of the time, but also make the occasional mistake. Our extraordinary speech-processing abilities Despite confusion over Armstrong’s words, speakers and listeners have a remarkable ability to agree on what is said and what is heard. When we talk, we formulate a thought, retrieve words from memory and move our mouths to produce sound. We do this quickly, producing, in English, around five syllables every second. The process for listeners is equally complex and speedy. We hear sounds, which we separate into speech and non-speech information, combine the speech sounds into words, and determine the meanings of these words. Again, this happens nearly instantaneously, and errors rarely occur. These processes are even more extraordinary when you think more closely about the properties of speech. Unlike writing, speech doesn’t have spaces between words. When people speak, there are typically very few pauses within a sentence. Yet listeners have little trouble determining word boundaries in real time. This is because there are little cues — like pitch and rhythm — that indicate when one word stops and the next begins. But problems in speech perception can arise when those kinds of cues are missing, especially when pitch and rhythm are used for non-linguistic purposes, like in music. This is one reason why misheard song lyrics — called “mondegreens” — are common. When singing or rapping, a lot of the speech cues we usually use are shifted to accommodate the song’s beat, which can end up jamming our default perception process. But it’s not just lyrics that are misheard. This can happen in everyday speech, and some have wondered if this is what happened in the case of Neil Armstrong. Studying Armstrong’s mixed signals Over the years, researchers have tried to comb the audio files of Armstrong’s famous words, with mixed results. Some have suggested that Armstrong definitely produced the infamous “a,” while others maintain that it’s unlikely or too difficult to tell. But the original sound file was recorded 50 years ago, and the quality is pretty poor. So can we ever really know whether Neil Armstrong uttered that little “a”? Perhaps not. But in a recent study, my colleagues and I tried to get to the bottom of this. First, we explored how similar the speech signals are when a speaker intends to say “for” or “for a.” That is, could a production of “for” be consistent with the sound waves, or acoustics, of “for a,” and vice-versa? So we examined nearly 200 productions of “for” and 200 productions of “for a.” We found that the acoustics of the productions of each of these tokens were nearly identical. In other words, the sound waves produced by “He bought it for a school” and “He bought one for school” are strikingly similar. But this doesn’t tell us what Armstrong actually said on that July day in 1969. So we wanted to see if listeners sometimes miss little words like “a” in contexts like Armstrong’s phrase. We wondered whether “a” was always perceived by listeners, even when it was clearly produced. And we found that, in several studies, listeners often misheard short words, like “a.” This is especially true when the speaking rate was as slow as Armstrong’s. In addition, we were able to manipulate whether or not people heard these short words just by altering the rate of speech. So perhaps this was a perfect storm of conditions for listeners to misperceive the intended meaning of this famous quote. The case of the missing “a” is one example of the challenges in producing and understanding speech. Nonetheless, we typically perceive and produce speech quickly, easily and without conscious effort. A better understanding of this process can be especially useful when trying to help people with speech or hearing impairments. And it allows researchers to better understand how these skills are learned by adults trying to acquire a new language, which can, in turn, help language learners develop more efficient strategies. Fifty years ago, humanity was changed when Neil Armstrong took those first steps on the Moon. But he probably didn’t realize that his famous first words could also help us better understand how humans communicate.

The moon is two-faced (probably because of a massive asteroid). Ours is a moon with two faces: the nearside boasts a thinner and smoother crust, while the farside crust is thicker and dotted by impact craters left nearly undisturbed by lava flows. The discrepancies have vexed scientists for decades, and in a new paper, researchers use models to explore what may be possible explanations for the stark differences. They argue that those distinctive sides could be the result of a giant impactor slamming into the moon and leaving a massive crater across the entire nearside.

The moon is shrinking and quaking. The moon is shrinking. And as the crust of our lone satellite contracts, it tugs on cliff-like cracks on the surface, leading to lots of moonquakes, researchers have discovered. Scientists revisited moonquake data gathered from 1969 to 1977 by seismic equipment on the Apollo lunar missions. They mapped the seismic data to satellite images of thrust faults, or scarps — stairstep cliffs on the lunar surface. These formations stand dozens of feet high and extend for miles, and they are visible in images captured by NASA’s Lunar Reconnaissance Orbiter. The researchers discovered that around 25% of the moonquakes were likely generated by released energy from these faults, rather than by asteroid impacts or activity deep inside the moon. Scarps are spread across the face of the moon in a vast, global network, and are estimated to be no more than 50 million years old, the researchers wrote. The age and distribution of the scarps hint that they appeared as the moon’s interior cooled down, causing its crust to contract.

There’s an enormous, dense blob of metal below the surface of the moon’s south pole. Deep below the moon’s South Pole-Aitken basin (the largest preserved impact crater anywhere in the solar system), researchers have detected a gargantuan “anomaly” of heavy metal lodged in the mantle that is apparently altering the moon’s gravitational field. According to a study of the mysterious blob, published April 5 in the journal Geophysical Research Letters, the anomaly likely weighs somewhere in the neighborhood of 2.4 quadrillion tons (2.18 quintillion kilograms). The researchers aren’t sure how this giant blob of metal got itself trapped below the lunar surface. Simulations suggest it could be the heavy remnants of the iron-nickel asteroid that crashed into the far side of the moon and created the giant South Pole-Aitken crater some 4 billion years ago.

In 2009, data from NASA’s Lunar Reconnaissance Orbiter (LRO) led to the discovery of water on the moon locked up in ice. A recent upgrade to the orbiter, called the Lyman Alpha Mapping Project (LAMP), has allowed scientists to take a closer look at the water on the lunar surface. LAMP has revealed that water molecules move around the moon as the lunar surface warms and cools throughout the day. Water remains stuck on the moon’s surface until the lunar midday, when some of the water melts and heats up enough to lift into the moon’s delicate atmosphere. The water floats around a bit until it reaches an area cool enough to make it settle back down to the surface.Advertisement Water on other planetary bodies could be a valuable resource for human explorers to not only drink but also to serve as fuel for future robotic exploration, since water can be split to form rocket fuel, saving missions from having to carry that fuel from Earth.

As the world begins its commemoration of the awe-inspiring first walk on the lunar surface, let’s review five of the most recent and fascinating scientific findings about the moon. 4. You won’t strike it rich on the moon. Gold, platinum and other metals known as highly siderophile (“iron-loving”) elements are far more abundant in Earth’s crust than they are in its natural satellite. That may seem odd, given the two worlds’ shared history. About 4.5 billion years ago, a Mars-size planet dubbed Theia slammed into the proto-Earth, blasting huge amounts of material from both bodies into space. Some of this liberated stuff was incorporated into the bruised and battered Earth, and some coalesced to form the moon. But highly siderophile elements (HSEs) appear to have been left out of the mix. These metals were likely delivered by later asteroid strikes — but why does Earth have so much more than the moon? The researchers suspect that the moon’s weaker gravitational pull means material delivered via impact isn’t as likely to have stayed on the moon as it did on Earth — lots of stuff that hits the moon returns to space. The small concentration of HSEs retained on the moon likely arrived before the moon’s magma ocean cooled and solidified, so the material became incorporated into the moon’s core.
