The Three Mile Island nuclear accident 40 years ago

Yahoo Science News feed latest items - Wed, 03/27/2019 - 14:08

The 1979 accident at the Three Mile Island power plant, the worst in US history, claimed no lives but provoked an outcry over the country's nuclear electricity program. Caused by mechanical, design and human errors, the partial meltdown registered a five on the International Nuclear Event Scale that peaks at seven, the rate given to the Chernobyl (1989) and Fukushima (2011) disasters. Here is a rundown of what happened on March 28, 1979 at one of the two reactors at the Three Mile Island Generating Station in eastern Pennsylvania.

More than 50 bowel surgery patients should not have been operated on by well-known doctor, hospital admits

Yahoo Science News feed latest items - Wed, 03/27/2019 - 14:01

More than 50 patients who were given a controversial form of bowel surgery by a well-known surgeon should not have been operated on, a hospital trust has admitted. Dozens of women were left in severe pain after pelvic floor surgery using artificial mesh at Southmead Hospital in Bristol. Tony Dixon, one of Britain's best known surgeons in the area, was suspended in 2017 after concerns were first raised and an inquiry examined 143 cases. Among them were Lucinda Methuen-Campbell, who underwent bowel surgery at a private hospital in 2016. She was allegedly told by Mr Dixon that her ovaries had been removed “because they were in the way” - a move that she had not authorised and which left her in agony. Ms Metheun-Campbell later took her own life after the vaginal mesh implant left her struggling to find any way out of the pain. Mr Dixon, who also worked at the private Spire Hospital in Bristol, pioneered the use of artificial mesh to lift prolapsed bowels - a technique known as laparoscopic ventral mesh rectopexy (LVMR) - often caused by childbirth. North Bristol NHS Trust has told 57 patients they should have been offered alternative treatment first following an investigation into their care. Another 73 patients considered by the review have been told the surgery they received was appropriate.

After concerns were raised about pelvic floor surgery, the trust began a review of the cases of women and men who underwent the procedure between 2007 and 2017. Dr Chris Burton, medical director of the North Bristol NHS Trust, said: "I want to apologise to all patients who have received surgery unnecessarily - it is unacceptable and we are taking it extremely seriously. "We took immediate action to ensure this couldn't happen again and have been supporting patients where they need it. "We will keep investigating to ensure we have identified those patients affected by these issues, and to find out what happened to learn lessons for future care." Law firm Irwin Mitchell represents 49 people who underwent surgery at Southmead and Spire hospitals and called on the trust to "openly publish its findings". Solicitor Sallie Booth said: "It is vital that reasons why this was allowed to happen are established." Irwin Mitchell has already agreed terms with North Bristol NHS Trust for a scheme to consider compensation. The General Medical Council has imposed sanctions on Mr Dixon, which includes not being allowed to carry out this type of surgery and runs until November 2019.

The ‘godfathers of AI’ just won this year’s Turing Award

Yahoo Science News feed latest items - Wed, 03/27/2019 - 13:51

Facebook's director of artificial intelligence research is one of three AI leaders who've won this year's Turing Award, sometimes referred to as the Nobel Prize of computing.This year's winners include Yann LeCun, a New York University professor who also works on AI at Facebook; Geoffrey Hinton, a University of Toronto computer science professor; and Yoshua Bengio, a computer scientist and professor at the University of Montreal. The award, announced by the Association of Computing Machinery, carries a $1 million prize, with financial support from Google, and it's named for famed British mathematician Alan Turing.ACM president Cherri Pancake said the growth of and interest in AI today is due "in no small part" to advances in deep learning made possible by this year's award winners. "Anyone who has a smartphone in their pocket can tangibly experience advances in natural language processing and computer vision that were not possible just 10 years ago," Pancake said. "In addition to the products we use every day, new advances in deep learning have given scientists powerful new tools -- in areas ranging from medicine, to astronomy, to materials science."AI has become an increasingly fundamental part of the way the world's largest social network operates, and according to the ACM Facebook's AI chief has been working on this since the 1980s. During that decade, for example, LeCun developed "convolutional" neural networks, a foundational principle in the field that's been essential in making deep learning more efficient.Facebook's founder and chief executive Mark Zuckerberg used his personal Facebook page to congratulate LeCun this morning, noting that the winners' combined work has "moved the entire field of AI forward."https://www.facebook.com/zuck/posts/10106981903745721This year's three winners have worked both independently, as well as together. Per the ACM, Hinton, LeCun and Bengio developed "conceptual foundations for the field, identified surprising phenomena through experiments, and contributed engineering advances that demonstrated the practical advantages of deep neural networks." LeCun performed postdoctoral work under Hinton's supervision, and LeCun and Bengio also worked together at Bell Labs in the early 1990s.The ACM will present the award to this year's recipients at a banquet on June 15 in San Francisco.

Science Says “Time-Restricted Eating” Can Help Stave Off Breast Cancer

Yahoo Science News feed latest items - Wed, 03/27/2019 - 13:31

According to the National Cancer Institute, one in eight women in the United States will develop invasive breast cancer over the course of her lifetime. (The risk increases exponentially after the age of 40, eventually doubling by the age of 70.) As with other types of cancer, smoking, being overweight, and regularly drinking alcohol can significantly increase your risk of breast cancer. But research has shown that your diet plays an important role, as well. Now, a new study whose findings were recently presented at the Endocrine Society’s annual meeting in New Orleans has shed light on a previously unknown factor in breast cancer development: when you eat plays an important role, too.In fact, it's so important that the new evidence suggests that it could prove to be more important than what you eat.For the study, researchers at the University of California in San Diego studied the effects of "time-restricted eating"—otherwise known as confining your food in-take to a certain window of the day when you're at your most active, but not reducing calories on the whole—on mice who were either obese or had been "injected with breast cancer cells."After a series of tests, the researchers ultimately found that, compared to mice who followed a regularly scheduled low-fat diet, the mice who followed time-restricted eating—regardless of the fat content contained in the food—showed dramatic signs of "delaying the development of tumors and reducing tumor growth."The question is: why?"The results suggest the anti-tumor effect of time-restricted eating is at least partially due to lowering levels of insulin," explained Manasi Das, a postdoctoral fellow at the University of California in San Diego and the lead author of the study.As scientists know all too well, high insulin levels are common in obese people and it's been linked to cancer over the course of several studies. For instance, according to one landmark Women's Health Initiative (WHI) study of 93,000 women during the 1990s, women with higher levels of insulin displayed more than double the risk of breast cancer than women with lower levels of insulin.Other studies have shown that time-restricted eating, as well as intermittent fasting—or not eating for certain extended periods of time—is effective at keep your insulin levels down. "Between meals, as long as we don’t snack, our insulin levels will go down and our fat cells can then release their stored sugar, to be used as energy," Monique Tello, M.D., wrote on the Harvard Medical School blog. "We lose weight if we let our insulin levels go down. The entire idea of [intermittent fasting] is to allow the insulin levels to go down far enough and for long enough that we burn off our fat."Meanwhile, UC San Diego's Das says that time-restricted eating shows promise in not only staving off cancer but also in promoting weight less—because it's much easier to do than your average calorie-slashing diet."Time-restricted eating may be more successful than calorie restriction in controlling the negative effects of obesity, due to the hunger and irritability that makes it more difficult to stick with long-term calorie restriction," wrote Das.Now, before you start setting reminders to eat at certain hours, it's important to remember that the study is limited in the fact that it was conducted on mice and not human subjects. But the results are nonetheless eye-opening.

Diabetes in pregnancy tied to future heart disease risk

Yahoo Science News feed latest items - Wed, 03/27/2019 - 13:06

While so-called gestational diabetes has long been linked to an increased risk of heart disease later in life, some previous research suggests this risk may depend on whether the condition evolves into type 2 diabetes that persists after delivery. Overall, about 8,000 women with a history of gestational diabetes experienced cardiovascular events like heart attacks and strokes, as did more than 93,000 women without this pregnancy complication. "This study demonstrates that women with gestational diabetes have a 2-fold higher risk of major cardiovascular events than their peers," said senior study author Dr. Ravi Retnakaran of the University of Toronto.
