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.
When the Obama administration's Food and Drug Administration gave way to the Trump era, there were a number of positive changes in how the federal government treated smoking cessation tools that were not controlled by large corporations. They rolled back the arbitrary framing that claimed all tobacco was as harmful as cigarettes - except Big Pharma products like nicotine patches and gums. They accepted that adults should have all options available for quitting cigarettes or at least reducing harm.
Methane detection in the Martian atmosphere haa been a source of debate because methane means a greater possibility for habitability and may even be a signature of life., but spacecraft and telescopic observations from Earth reported no detections of methane, at least not outside the realm of statistical wobble.Finally, independent measurements report a firm detection in the Martian atmosphere above Gale Crater on 16 June 2013 by the Planetary Fourier Spectrometer onboard Mars Express, one day after the in situ observation of a methane spike by the Curiosity rover.
Air in England, the United States and most of Europe is now cleaner than it's been in over a century, but you wouldn't know that if you read populist epidemiology claims, which have redefined pollution from PM10, dangerous soot like black carbon, to PM2.5, which you can only detect with an electron microscope, and even down to PM1.0, which might as well be virtual pollution.
The U.S. Food and Drug Administration today approved Mayzent (siponimod) tablets by Novartis to treat adults with relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.
Discussion of the periodic table of elements often ends with simply invoking Dmitri Mendeleev, the Russian chemist who formulated the Periodic Law and used it to correct the properties of some already discovered elements, not to mention predicting the properties of eight elements yet to be discovered.But instead of being foundational, it would have been just a quaint paper in a mining journal. had its development ended there. Mendeleev had been appointed him professor of general chemistry in 1867 and was required to lecture on inorganic chemistry. Lacking a good Russian textbook, he decided to write one, and that required truly arranging the chemical elements, something that had eluded other scholars.
The largest Tyrannosaurus rex skeleton discovered so far, and therefore the largest carnivore on land currently known to science, was discovered in 1991 in Saskatchewan, Canada, but the extremely hard matrix surrounding the bones, in combination with the size of the skeleton of Tyrannosaurus rex (RSM P2523.8), made it especially difficult and time-consuming to remove, assemble, and study. Since is is relatively complete (roughly 65 percent), RSM P2523.8 has finally been described in The Anatomical Record: Advances in Integrative Anatomy and Evolutionary Biology.
The Scandinavian wolf population is a bit of an evolutionary mystery. In the hoped for descent with modification scenario, textbook natural selection, there would be signs that hybrids of dog and wolf have contributed to this population, but none have been found. Wolf-dog hybrids – crosses between wolf and dog – are known from many parts of the world and have mainly been the result of male dogs mating with female wolves. One such hybrid was found south-west of Stockholm, in 2017; another turned up near Oslo 20 years ago. In the Storting, the Norwegian parliament, the question has been raised of whether the wolves returning to Scandinavia in the 1980s, after they had been virtually exterminated, even had some elements from dogs in their genetic ancestry.
A small survey in Australia (n=442) found that more than half of car drivers think cyclists are not really human, and many admit to intentionally driving too close to them. The survey says it is the first to look at a road-user group with the problem of dehumanization, which is typically studied in relation to attitudes towards racial or ethnic groups. The authors state that cyclists have been conceptualized as a minority group and a target of negative attitudes and behavior - but if drivers can put a human face to cyclists, researchers say it could reduce aggression directed at cyclists and road trauma involving riders.
Americans with more formal education fare better on science-related questions, minorities fare worse, and Republicans and Democrats are roughly similar in their overall levels of science knowledge. according to a new study released today by Pew Research Center.
Since the oldest millennials are now nearing 40 it may be time for sociologists and psychologists to stop writing papers on how much nurturing they will need when they arrive. They are already here.
Yet papers will keep coming, perhaps until people stop wanting to read them.
A new paper in The Journal of Social Psychology claims that how well parents or guardians support millennials' psychological needs prior to their transition to college is an important predictor of their psychological well-being as they adapt to college life.
As if mothers don't get blamed for enough, a new paper claims attention deficit hyperactivity disorder (ADHD)may have been caused by her diet during pregnancy.
The results of a study led by a team from the Barcelona Institute for Global Health (ISGlobal), a centre supported by "la Caixa", suggest that the risk of a child developing symptoms of attention deficit hyperactivity disorder (ADHD) may be modulated by the mother's diet during pregnancy. The study, published in the Journal of Pediatrics, analysed samples of umbilical cord plasma to quantify the levels of omega-6 and omega-3 that reach the foetus. The statistical analysis showed a higher omega-6:omega-3 ratio to be associated with a higher risk of ADHD symptoms at seven years of age.
A woman in Scotland can feel virtually no pain due to a mutation in a previously-unidentified gene, FAAH-OUT, according to a new research paper in the British Journal of Anaesthesia.
She also experiences very little anxiety and fear, and may have enhanced wound healing due to the mutation
