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.
More than half of the streamflow in the Upper Colorado River Basin originates as groundwater, according to a new U.S. Geological Survey study published today in the journal Water Resources Research.
With the move from burning coal to natural gas and low-sulfur coal and an increase in the use of scrubbers, only about 25 percent as much atmospheric sulfur is available today, compared to 40 years ago.
Sulfur balances in agricultural fields are now negative, with more removed each year in crop harvests and leaching than is added from fertilizers and deposition.
Bethesda, MD (May 9, 2016) -- About 1.8 million Americans have celiac disease, an immune-based condition brought on by the consumption of gluten in genetically susceptible patients. Among patients diagnosed with celiac disease by small intestinal biopsy in the U.S., those from the Punjab region of India have the highest rates of disease, according to new research published in Clinical Gastroenterology and Hepatology,1 the official clinical practice journal of the American Gastroenterological Association.
By now we are all used to seeing its more or less successful results on Italian and international celebrities, but in fact the market of Botox-based procedures (cosmetic treatments that exploit the effects of type A botulin toxin) involves a large number of individuals. Just to give an idea, about 250,ooo procedures were done in Italy in 2014. It is therefore natural to wonder about the possible side effects of this practice. One fairly unpredictable consequence concerns the emotional domain, and in particular the perception of emotional information and facial expressions.
Researchers from the University of Chicago have shown that inhibiting autophagy, a self-devouring process used by cells to degrade large intra-cellular cargo, effectively blocks tumor cell migration and breast cancer metastasis in tumor models. In a study, published May 12, 2016, in the journal Cell Reports, they demonstrate that the process is essential for tumor metastasis and describe the mechanisms that connect autophagy to cell migration.
Same-sex sexual behaviour is common in animals but puzzles evolutionary biologists since it doesn't carry the same obvious benefits as heterosexual courtship behavior that leads to mating and production of offspring. A study from Uppsala University sheds new light on the pervasiveness of same-sex sexual behaviour in the animal kingdom.
Having analyzed the data collected for more than three decades, scientists managed to show that the effects of climate changes in the Arctic may come out on a completely different continent, a few thousand kilometers away from the Arctic ice. One of the authors, Eldar Rahimberdiev, researcher at the Biological faculty of MSU, says that the work is unique, as earlier scholars did not consider these problems so complex.
Although ski season is behind us, serious skiers are already looking ahead to next season and searching for ways to shave split-seconds off their race times. Now scientists may have a new way to help -- perhaps in time for the next Winter Olympics. One team has determined how the microscopic texture of the bottoms of skis could affect their speed, depending on snow temperature. Their study appears in the journal ACS Applied Materials & Interfaces.
Why is the WebMD website so successful? Last week, John Oliver ridiculed them for promoting every suspect association between anything and cancer, without any analysis or critical thinking.
A new paper paper in the journal Communication Research may provide some answers. They are publishing churnalism and advertorials about science and health, and that is far more effective than the numerous advertisements they carry.
Diagnoses of celiac disease (CD), an autoimmune disease, are increasing, no real surprise after not one but two bestselling food books based on suspect studies claimed wheat is poison.
Psychologically, women may not like much competition, according to a female psychologist, and that may account for inequality in academia and the work force.
If that is true, though, why is psychology 70 percent women? There is just as much competition, it just isn't men. It may be that because psychology has a smaller monetary reward, women feel more communal than competitive, according to Dr. Kathrin Hanek, the study's lead author.
EAST LANSING, Mich. - A rare, severe form of pulmonary hypertension, which up until now, has only been classified as a human lung disease, has also been discovered in dogs according to a Michigan State University study.
"Our research is the first to document the existence of pulmonary veno-occlusive disease, or PVOD, in dogs," said Kurt Williams, the lead author of the study and an expert in respiratory pathology in MSU's College of Veterinary Medicine. "PVOD is considered one of the most severe forms of pulmonary hypertension."
The study is published in the journal Veterinary Pathology.
