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 underlying central metaphor of the new Marvel film "Spider-Man: Far From Home" is that news shouldn't be trusted. Many agree, but whether or not people label it "fake" seems to be based on how different their own bias is.If you are a Republican and regard CNN is biased, having a conservative voice on their network does not make the outlet seem less biased, it makes the participant seem less credible, even if they believe the individual is honest.
The fossilized skull of a Paleolithic adult man from around 33,000 years ago and known as the Cioclovina calvaria has been extensively studied. But there was controversy over trauma on the skull--specifically a large fracture on the right aspect of the cranium and whether that specific fracture occurred at the time of death or as a postmortem event.Computer simulations using twelve synthetic bone spheres tested scenarios such as falls from various heights as well as single or double blows from rocks or bats. Along with these simulations, the authors inspected the fossil both visually and virtually using computed tomography technology.
Our bodies can deploy biomolecules to find, tag and destroy invading pathogens. They work by binding to specific targets, called epitopes, on the surfaces of antigens - like locks to keys.This selective tagging mechanism in natural antibodies has been valuable in engineering antibody-based probes that let them purify and study different types of proteins within cells. One technique, epitope tagging, involves fusing an epitope to a protein of interest and using fluorescently labeled antibodies to make those proteins visible - but only in fixed, dead cells.
Though numerical models don't always correlate with reality, a new paper states that the world can achieve a 2 degree Celsius climate-stabilizing goal and reach net-zero emissions by mid-century, without closing newer plants that, let's be honest, no country is going to close.
Changes in spring surface air temperature can vary widely and even impact socioeconomics in developing countries so it will be important to learn how to predict the variations of spring temperatures. However, the dynamics and predictability of East Asian temperatures during boreal spring are more challenging compared to those in the other seasons. Part of the difficulty is due to the spring predictability barrier. The predictive skill based on El Niño-Southern Oscillation decreases rapidly during boreal spring. For as long as climate change has been a concern El Niño has been considered a confounder.
A 65-year follow-up study of 6,883 patients with Multiple Sclerosis suggests they have a greater overall risk of developing cancer than the general population, with an especially high risk of cancer in respiratory organs, urinary organs and the central nervous system.Multiple sclerosis is a lifelong disease that affects the central nervous system, especially the brain, spinal cord and optic nerves. It can lead to a wide range of symptoms, including problems with vision, arm or leg movement, sensation or balance. MS is one of the most common causes of disability in younger adults, and people with MS have on average 7 years shorter longevity.
It's generally believed that if you are going to be heavy, pear-shaped (fatter) in the waist and legs) is better than apple (fat around the chest) and a new study validates that holds true for postmenopausal even if they are not heavy and have a normal, healthy body mass index (BMI).That requires some context. BMI is a fine population-level metric but generally useless for individuals. If you have a high BMI but know you are fit, don't think you need to shed muscle mass to lose weight. In postmenopausal women, storing a greater proportion of body fat in the legs (pear-shaped) whether having high BMI or not was linked to a significantly decreased risk of cardiovascular disease.
We've all offered an excuse for a poor reaction or any behavior we recognize we should not have engaged in; many have rationalized it to mitigate consequences or even make it socially acceptable. Stress, headaches, even ignorance can be proffered, but what makes an excuse plausible? In law, things are a little more clear, duress and coercion and psychological maladies have all been successful, but to families and friends it might not be as easy as convincing a jury of strangers. Especially if you do it often.
At the recent Academy of Neurology Congress, scholars reported that among 1,034 people recruited from 35 countries via an online crowdsourcing platform asked if they'd ever had an Near Death Experience, 289 answered 'yes.' When were asked for more details, using a 16 point questionnaire called the Greyson Near-Death Experience Scale, 106 reached a threshold of 7 on the Greyson NDE Scale. Some 55 percent perceived the their feeling as truly life-threatening.Among respondents, 73 percent who claimed a near death experience said it was unpleasant, but those with a score of 7 or above on the Greyson NDE Scale had 53 percent pleasant descriptions of it.
Doctors, like scientists, often aren't big on putting themselves into stories and getting selfies with patients, or even accepting pictures as part of care. But selfies are a part of modern culture, and that means they are empowering to patients, so allowing pictures from patients and parents of patients may streamline health care and also keep costs lower.
DDT and other chemicals remain the most effective way to contain malaria - by eliminating the disease vectors that spread it.But even though the U.S. EPA has written the book for how DDT is to be sprayed inside homes, it was banned here over the objections of scientists and remains controversial for environmental groups who want to ban all chemicals. A new method may make chemicals less necessary but it involves another area of science activists oppose; genetic engineering.
For those who used to believe that taking on massive student loan debt to pay for increased salaries for university employees that would lead to a high salary, a new reality has set in: the gig economy. And that counts in journalism too. In the days of Walter Cronkite and Watergate, media enjoyed a great deal of trust, but as the public got more savvy about bias that trust declined and people began to seek out alternative sources. If media are going to be biased, people believed, it might as well be biased in ways they like.
