More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
The manufacture of cement, bricks, bathroom tiles and porcelain crockery normally requires a great deal of heat: a kiln is used to fire the ceramic materials at temperatures well in excess of 1,000°C. Now, material scientists from ETH Zurich have developed what seems at first glance to be an astonishingly simple method of manufacture that works at room temperature. The scientists used a calcium carbonate nanopowder as the starting material and instead of firing it, they added a small amount of water and then compacted it.
Data from online video games has been used to study what kinds of practice and habits help people acquire skill. Basically, what does it take to get good? 10,000 hours, as Malcom Gladwell said? Nope, not even close. But there are reasons why some people are great in The Division and you die in the Dark Zone within seconds after meeting another player. Basically, they learned shortcuts and before they ever met you, they warmed up.
Adolescents with autism spectrum disorder use 400 percent more emergency room services than peers without it, which puts more strain on an over-burdened health care system and may mean that they need better access to primary care.
Russian author Boris Zhitkov wrote the 1931 short story Microhands, in which the narrator creates miniature hands to carry out intricate surgeries. And while that was nearly 100 years ago, the tale illustrates the real fundamentals of the nanoscience researchers are working on today.
Some people have an extreme fear of spiders or other objects while others have breathing difficulties and accelerated heart beat in small rooms or large gatherings of people. Some anxiety attacks occur for no apparent cause. Some patients suffer from the detrimental impacts on their everyday lives, they have problems at work and withdraw from social contacts.
A new observational study claims that cheese increases breast cancer risk, while yogurt can lower it. Since both are dairy, that means they would be suggesting a dairy process causes or prevents cancer. The case control study has numerous confounders that will not be noticed by most journalists so media outlets looking for context beware.
A new fMRI study used neural activity in 80 people to accurately predict the virality of 80 New York Times health articles.Well, it's the New York Times, a top five newspaper in the U.S. so the results are going to be skewed by that, as were the articles selected; the public loves weak observational claims about health and the demographic that reads the New York Times is most inclined to believe claims about miracle vegetables, scary chemicals and diet fads.
There are multiple food fads trying to catch on per year but as the saying goes in science, if one epidemiology study counted, everything would cause or prevent cancer.One long-held epidemiology belief is that the more vegetables you eat, the healthier your heart will be. While vegetarians and animal activists tout such claims, the actual evidence is not clear. In recent decades we've been told bacon, butter and red meat all cause heart disease. But the same groups scaremongering food have also claimed that coffee causes breast cancer, that cell phones cause all kinds of cancer, and that BPA can be an endocrine disruptor, even though they are biological and toxicological impossibilities.
You might think that after the November elections, the last group anyone will listen to for guidance on the American public are partisan pundits. But they are still lobbying for an alternative result, now saying that if President Trump wants to honor his commitment to repealing the The Patient Protection and Affordable Care Act (Obamacare) while allowing more coverage, better benefits, and lower costs, the only choice is a Single Payer system; socialized medicine.They list now-famous pretend money, the same optimistic estimates that led to the Obamacare system being financially viable, savings of $504 billion annually on health care bureaucracy and profits.
Zika virus can cross the placenta, intended to protect the developing fetus, and appears to lead to a high percentage of miscarriages and to babies born with thin brain tissue and inflammation in brain cells, at least in mice.Mice are not little people, of course, or every disease would have been cured by now and every chemical would be toxic, but it's a starting point for understanding the role of zika in birth defects beyond vague epidemiology.
No-till farming uses cover crops to conserve soil and suppress weeds but many vegetable producers haven't embraced it yet. The reason is simple; small-seeded vegetable crops struggle to emerge through thick cover crop residues. A recent program sought to see how it might work better with string beans, a common staple of many dinners, and possessing larger seeds. In both Illinois and Washington, USDA-ARS agronomist Rick Boydston and University of Illinois ecologist Marty Williams grew vetch, rye, and a combination of the two cover crops before killing them with a roller-crimper—a machine that evenly flattens and crimps standing plant biomass—or with a combination of the roller-crimper and a burndown herbicide.
Women who received a health scare in the form of a false positive result from a screening mammogram were more likely to delay or even forgo the next mammogram than women who had a correct negative result.A false positive result from a screening mammogram often leads to emotional, physical, and economic stress, though false positives are an expected part of proper medical care. For this study, the authors obtained data for women who received mammography screening through a large health care organization with multiple facilities in the greater metropolitan Chicago area. Among the 741,150 screening mammograms from 261,767 women included in the analysis were 12.3 percent that yielded a false positive result; the remaining 87.7 percent yielded true negative results.
