Proteins are essential for every living cell and responsible for many fundamental processes. In particular, they are required as bio-catalysts in metabolism and for signalling inside the cell and between cells. Many diseases come about as a result of failures in this communication, and the origins of signalling in proteins have been a source of great scientific debate. Now, for the first time, a team of researchers at the University of Göttingen has actually observed the mobile protons that do this job in each and every living cell, thus providing new insights into the mechanisms.
An internationally respected group of scientists, including Professor Francois Engelbrecht from the University of the Witwatersrand, Johannesburg, have urgently called on world leaders to accelerate efforts to tackle climate change. Almost every aspect of the planet's environment and ecology is undergoing changes in response to climate change, some of which will be profound, if not catastrophic, in the future.
MEDFORD/SOMERVILLE, Mass. (Sept. 19, 2019)--College-student voting rates in the 2018 midterm elections doubled compared to the 2014 midterms, marking a watershed election year for student voter turnout, according to a report today from the Institute for Democracy & Higher Education (IDHE) at Tufts University's Tisch College of Civic Life. The report, Democracy Counts 2018, is based on an analysis of the voting patterns of more than 10 million college students on more than 1,000 campuses participating in the National Study of Learning, Voting, and Engagement (NSLVE).
In order to meet the demands of growing human populations, agricultural production must double within the next 30 years. Yet the health of today's crops and the promise of their yield face a rising slate of threats--from pests to chaotic weather events--leading to an urgent need to identify effective, natural plant defense strategies.
EVANSTON, Ill. -- Your intuition is correct. You are more likely to become a victim of a crime if you live in a big city.
Researchers have long known that bigger cities disproportionately generate more crime. Now a new study from Northwestern University and the Santa Fe Institute explains why: It's easier for criminals to find collaborators.
Morris Animal Foundation-funded researchers at Oregon State University discovered areas in the African buffalo genome linked to risk for TB infection. Their finding also demonstrates the complex interplay between host immune responses and spread of infectious disease.
In a paper published in the latest issue of the American Journal of Psychotherapy, McLean Hospital clinicians describe the success of the hospital’s Spiritual Psychotherapy for Inpatient, Residential & Intensive Treatment (SPIRIT) program. The clinicians drew their conclusions from a sample of nearly 1,500 patients.
AURORA, Colo. (Sept. 19, 2019) - Nearly half of all Catholic and other religious hospitals fail to comply with required abortion and family planning training for obstetrics and gynecology residents, putting women at potential risk, according to a new study from the University of Colorado Anschutz Medical Campus.
The study was published online this month in the American Journal of Obstetrics & Gynecology.
CHICAGO - A new study finds that individuals thought to be at an increased risk of developing Alzheimer's disease and also have high blood pressure and a higher risk of developing heart disease (based on a Framingham risk score), may also have a faster accumulation of tau tangles, one of the hallmarks of Alzheimer's disease. The authors conclude that risk factors including high blood pressure, high cholesterol levels and weight management should be monitored from midlife onward to detect early changes that may be related to Alzheimer's.
East Hanover, NJ. September 19, 2019. A recent review by Kessler Foundation researchers explored the relationship between neuropsychological assessment and predictability of performance of everyday life activities among people with multiple sclerosis (MS). The article, "Beyond cognitive dysfunction: Relevance of ecological validity of neuropsychological tests in multiple sclerosis," was epublished on August 30, 2019 by the Multiple Sclerosis Journal in a special issue on rehabilitation.
Using polymers and natural stone slurry waste, UBC Okanagan researchers are manufacturing environmentally friendly stone composites.
These new composites are made of previously discarded materials left behind during the cutting of natural structural or ornamental blocks for buildings, construction supplies or monuments. While reusing the waste material of natural stone production is common in cement, tile and concrete, adding the stone slurry to polymers is a new and innovative idea, explains School of Engineering Professor Abbas Milani.
BOZEMAN - A team of researchers in Montana State University's College of Agriculture has discovered a previously unidentified microbe that lives symbiotically with the wheat stem sawfly, a pest that causes hundreds of millions of dollars in damage to wheat crops each year. The discovery, the result of a years-long project, provides the basis for future research that could be vital to combating losses due to wheat stem sawflies in Montana and beyond.
If you could travel back in time 100,000 years, you'd find yourself living among multiple groups of humans, including anatomically modern humans, Neanderthals, and Denisovans. But exactly what our Denisovan relatives might have looked like had been anyone's guess for a simple reason: the entire collection of Denisovan remains includes a pinky bone, three teeth, and a lower jaw. Now, researchers reporting in the journal Cell have produced reconstructions of these long-lost relatives based on patterns of methylation in their ancient DNA.
Our everyday lives rely on planned movement through the environment to achieve goals. A new study by MIT neuroscientists at The Picower Institute for Learning and Memory identifies a well-connected brain region as a crucial link between circuits guiding goal-directed movement and motivated behavior.
