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.
Women who have high alcohol intake, 14 or more servings of alcohol a week are slightly more likely to have reduced fertility, suggests a study published in The BMJ today.
In developed countries, up to 24% of couples experience infertility, defined as time to pregnancy of 12 months or more. Official guidelines in countries like the USA, UK and Denmark recommend that women trying to become pregnant should abstain from alcohol consumption. But the extent to which alcohol intake affects female fertility is unclear. So a group of Danish researchers carried out a large prospective cohort study to examine the association between pre-conception alcohol consumption and time to pregnancy.
In comics, Clark Kent looks a lot like Superman, so similar every child has to wonder why no one puts it together. A pair of glasses on Kent, and a small lock of hair on Superman's forehead, are the only differences.
Yet that's probably enough, according to a new paper. Small alterations to
a person's appearance, such as wearing glasses, can significantly hinder positive facial identification.
A new study from the Northern Medical Program at the University of Northern British Columbia has shown that minimum legal drinking age (MLDA) legislation in Canada can have a major effect on crimes committed by young adults. Young people just older than the legal age had significant increases in commission of all crimes, including violent crimes and nuisance crimes, compared to those immediately under the restriction.
Greater understanding of the importance of environmental enrichment in enhancing an animal's physical and social environment is bringing benefits for pet cats - particularly those that are kept solely indoors.
If you recall dengue concerns in Florida in 2012...well, you probably don't. It never happened. Likewise with Ebola, SARS, Avian flu, you name it and it has been called an epidemic, and the NIH and the CDC have told Congress they need more money to fix it. Yet those epidemics never happened. Meanwhile, people sounding the alarm can rightly say that precaution is why the epidemics never happened.
Your choice of smartphone provides valuable information about you, according to a new social psychology paper. That's right, not only is your choice of smart phone indicative of your personality.
Two newer epilepsy drugs may not harm the thinking skills or IQs of school-aged children whose mothers took them while pregnant - but an older drug is linked to cognitive problems in children, especially if their mothers took high doses - according to new research from The University of Manchester.
Valproate, one of the most commonly prescribed antiepileptic medications, has been associated in the past with birth defects and developmental problems. However, two newer drugs - levetiracetam and topirimate - have had little or no investigations into their developmental impact until this latest research, published published in the August 31, 2016, issue of Neurology®, the medical journal of the American Academy of Neurology.
In the wake of Hillary Clinton's historic nomination as the first woman presidential candidate of a major political party in the U.S., women continue to face obstacles in politics and the workplace, according to a national poll conducted by The Associated Press-NORC Center for Public Affairs Research. Three-quarters of Americans think there is at least some discrimination against women in this country, although just as many say it has decreased over the past generation.
When it comes to developing test questions, there's the ordinary way and the fancy way. The ordinary way is to just make up questions and put them on the test. However, this can lead to questions that are misleading, confusing, or simply don't test for the knowledge you're trying to measure. The fancy way takes a lot of possible questions, tries them out on students, and whittles them down to the most useful. But this process is both time-consuming and expensive.
A group of researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) has found a way for schools, professors, textbook publishers, and educational researchers to check the quality of their test questions that turns out to be both fast and cheap. It invokes the power of crowdsourcing.
New research from the University of Chicago investigates what happens to men's and women's sexual function and relationships after a heart attack in an effort to help clinicians develop better care guidelines for patients. The study, published in JAMA Cardiology, shows impaired sexual function or new problems are common after heart attacks. They occur at the same rate as a loss of general physical function and at a higher rate than the incidence of depression after heart attack, but rarely do health care providers address these issues - particularly with women.
Human occupation is usually associated with deteriorated landscapes, but new research shows that 13,000 years of repeated occupation by British Columbia's coastal First Nations has had the opposite effect, enhancing temperate rainforest productivity.
Andrew Trant, a professor in the Faculty of Environment at the University of Waterloo, led the study in partnership with the University of Victoria and the Hakai Institute. The research combined remote-sensed, ecological and archaeological data from coastal sites where First Nations' have lived for millennia. It shows trees growing at former habitation sites are taller, wider and healthier than those in the surrounding forest. This finding is, in large part, due to shell middens and fire.
ITHACA, NY-- Tomatoes are already an ideal model species for plant research, but scientists at the Boyce Thompson Institute (BTI) just made them even more useful by cutting the time required to modify their genes by six weeks.
