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 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
The more intensive and narrow the agricultural process, the more intensive the greenhouse gas emissions - which means your organic vegetables, wild-caught salmon, and free-range grass fed beef is a larger contributor to climate change than modern farming techniques.And that means rich White people disproportionately affect the environment through their eating habits, according to a new report in the Journal of Industrial Ecology.The report looks at what different demographic populations eat and was undertaken to get a better understanding of the environmental impacts of the food consumption patterns of major demographic groups.
Supplement distributor USA LESS has been forced to recall all of its LEOPARD Miracle Honey, which touts itself as "an instant source of energy and enhancement of male vitality", from stores because the U.S. Food and Drug Administration discovered why it works for male vitality.It's not their bogus mixture of rainforest herbs such as Tongkat Ali root, Ginseng root, Carob and Cinnamon, it's the presence of actual Sildenafil, the active ingredient in Viagra.
In Washington state, once retail sales were legalized, marijuana use by 8th and 10th graders actually declined.An obvious argument is that by legalizing it, the black market began to evaporate, and ethical vendors with legal businesses to lose are less likely to give it to children. Smoking is a "pediatric" disease because if people don't take it up early, they likely never will. But when criminals are the source of something, it becomes cool to rebellious teens, and consorting with criminals adds another layer of risk.
