Abrupt thawing of permafrost will double previous estimates of potential carbon emissions from permafrost thaw in the Arctic, and is already rapidly changing the landscape and ecology of the circumpolar north, a new CU Boulder-led study finds.
Behavioral therapy assisted by a smartphone app, delivered via telemedicine by a health coach, was an effective treatment for several symptoms of binge eating disorders, according to a study conducted by researchers from the Icahn School of Medicine at Mount Sinai and published this week in The American Journal of Psychiatry.
February 3, 2020 - With a new focus on quality of care and outcomes achieved, healthcare organizations are challenged to make the transition to value-based care. A model called the Value Transformation Framework (VTF) provides a structured, step-by-step approach to help guide the shift to value-based healthcare, reports a paper in the Jo
ANN ARBOR--The herbicide Roundup is the most widely used agricultural chemical in history. But over the past two decades, a growing number of weed species have evolved resistance to Roundup's active ingredient, glyphosate, reducing the product's dominance somewhat.
Research on the genetic basis of glyphosate resistance has focused largely on target-site resistance, which involves mutations to the single gene that encodes the plant protein disrupted by the herbicide.
MEDFORD/SOMERVILLE, Mass. (February 3, 2020)-- Habitat loss, pesticide use and, surprisingly, artificial light are the three most serious threats endangering fireflies across the globe, raising the spectre of extinction for certain species and related impacts on biodiversity and ecotourism, according to a Tufts University-led team of biologists associated with the International Union for the Conservation of Nature.
Five years ago, a team of computer scientists, biomedical researchers, and bioinformaticians set out to bring the power of collective knowledge to genomic research. Their new publication in PLOS Biology shares the culmination of that effort, an analytical platform that guides researchers through the process of interpreting complex genomic datasets.
Many of the biggest questions in physics can be answered with the help of quantum field theories: They are needed to describe the dynamics of many interacting particles, and thus they are just as important in solid state physics as in cosmology. Often, however, it is extremely complicated to develop a quantum field theoretical model for a specific problem - especially if the system in question consists of many interacting particles.
(Boston)-- The benefits of yoga have been widely documented by scientific research, but previously it was not clear as to how yoga exerts its physiologic effect.
Now a new study from Boston University School of Medicine (BUSM) proposes that yoga can increase levels of Gamma-amino butyric acid (GABA) in the short-term and completing one yoga class per week may maintain elevated GABA that could mitigate depressive symptoms.
Oil poses a considerable danger to aquatic life. Researchers at the Universities of Bonn and Aachen and the Heimbach-GmbH have developed a new technology for the removal of such contaminations: Textiles with special surface properties passively skim off the oil and move it into a floating container. The scientists used surfaces from the plant kingdom as a model. The study has now been published in the journal "Philosophical Transactions A".
For over a century, Alzheimer's disease has confounded all attempts to treat it. But in recent years, perplexing experiments using flickering light have shown promise.
Now, researchers have tapped into how the flicker may work. They discovered in the lab that the exposure to light pulsing at 40 hertz - 40 beats per second - causes brains to release a surge of signaling chemicals that may help fight the disease.
ABERDEEN PROVING GROUND, Md. (Feb 3, 2020) -- A big data approach to neuroscience promises to significantly improve our understanding of the relationship between brain activity and performance.
Darwin's finches are among the most celebrated examples of adaptive radiation in the evolution of modern vertebrates and now a new study, led by scientists from the University of Bristol, has provided fresh insights into their rapid development and evolutionary success.
Study of the finches has been relevant since the journeys of the HMS Beagle in the 18th century which catalysed some of the first ideas about natural selection in the mind of a young Charles Darwin.
Researchers at Johns Hopkins Bloomberg School of Public Health have discovered a fundamental mechanism that regulates gene activity in cells. The newly discovered mechanism targets RNA, or ribonucleic acid, a close cousin of DNA that plays an important role in cellular activity.
The discovery, detailed in a paper published February 3 in the journal Molecular Cell, is a significant addition to the foundational understanding of how gene activity is regulated, and may ultimately lead to powerful new medical treatments.
A 52-year database of the distribution and movements of 35 Atlantic shark species revealed new information on some of the least known species. It also uncovered a few surprises about where sharks go and how long they live.
Salmonella is a key cause of foodborne gastroenteritis around the world, with most outbreaks linked to eggs, poultry meat, pork, beef, dairy, nuts and fresh produce.
Now Flinders University researchers have found a simple solution for preventing salmonellosis affecting eggs through surface contamination, giving crucial help for food services industries.
