Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
The regulation and function of sleep is one of the biggest black boxes of today's brain science. A new paper published online on August 2 in the journal Brain Structure & Function finds that rapid eye movement (REM) sleep is suppressed by adenosine acting on a specific subtype of adenosine receptors, the A2A receptors, in the olfactory bulb. The study was conducted by researchers at Fudan University's School of Basic Medical Sciences in the Department of Pharmacology and the University of Tsukuba's International Institute for Integrative Sleep Medicine (WPI-IIIS). The research team used pharmacological and genetic methods to show that blocking A2A receptors or neurons that contain the A2A receptors in the olfactory bulb increases REM sleep in rodents.
We see all of the rosy claims coming from the Federal government about unemployment rates yet around us we see no one can buy a home, young people have resigned themselves to living with their parents, and the deficit this year has climbed at a rate that is unprecedented.It's because government unemployment statistics only tally people who get unemployment, and unemployment checks expire. It does not count people who have given up or who are chronically unemployed but that shows we have been in a period of stagnation for almost 10 years. Labor Day is about to arrive but since 2009 it has become less meaningful than ever. U.S. labor force participation at 62 percent and declining, which means it could soon be below 50 percent.
A popular belief that there is a higher number of births around the full moon has been shown to be true for dairy cows by a group of University of Tokyo researchers.
Previous studies have found conflicting evidence on the moon cycle affecting the timing of human births and many researchers remain unconvinced that the moon influences human births.
Associate Professor Tomohiro Yonezawa of the Graduate School of Agriculture and Life Sciences explains that the results may have varied because "multiple factors, such as the mothers' nutrition, social environment, and genetic background could disguise the moon's influence. However, cows may provide a good model for teasing apart the lunar effect from other factors that also influence birth."
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.
