The Torridon sandstone in northwestern Scotland preserves six kilometers of river sediment from Precambrian times. But what sort of geological events were able to leave their mark for researchers to find 1 billion years later?
Intriguingly, it was not great floods or dramatic course changes -- mostly just the regular crawl of sand dunes across the river bottom. In fact, only a few months' worth.
For the first time, data from LHCb, a major physics experiment, will be processed on a farm of GPUs. This solution is not only much cheaper, but it will help decrease the cluster size and process data at speeds up to 40 Tbit/s. The research paper has been published in Computing and Software for Big Science. https://cds.cern.ch/record/2717938/files/LHCB-TDR-021.pdf
Rescue rafts are a lifesaver, although other types of rafts may put our lives in danger: that is the case with 'lipid rafts', which are exploited by coronaviruses to attack human cells. An interdisciplinary research group coordinated by the University of Trento and the University of Napoli - Federico II set out to understand what happens when a virus jumps on this type of raft to invade a cell.
HOUSTON - (June 16, 2020) - Like finding that needle in the haystack every time, your T cells manage what seems like an improbable task: quickly finding a few invaders among the many imposters in your body to trigger its immune response.
T cells have to react fast and do so nearly perfectly to protect people from diseases. But first, they need a little "me" time.
Rice University researchers suggest that has to do with how T cells "relax" in the process of binding to ligands -- short, functional molecules -- that are either attached to the invaders or just resemble them.
Chintan Parekh, MD, of the The Saban Research Institute of Children's Hospital Los Angeles, has led a team of investigators that generated a comprehensive roadmap for how T-cells develop in the human thymus. The study will be published in the journal Immunity on June 16.
Researchers from the University of Bath have developed motion capture technology that enables you to digitise your dog without a motion capture suit and using only one camera.
The software could be used for a wide range of purposes, from helping vets diagnose lameness and monitoring recovery of their canine patients, to entertainment applications such as making it easier to put digital representations of dogs into movies and video games.
CHAPEL HILL, NC - Results from a six-month, multi-site clinical trial called the Wireless Innovation for Seniors with Diabetes Mellitus (WISDM) Study Group have been published by the Journal of the American Medical Association (JAMA).
Although most broken bones can be mended with a firm cast and a generous measure of tender loving care, more complicated fractures require treatments like bone grafting. Researchers at Texas A&M University have now created superior bone grafts using primitive stem cells. They found that these cells help create very fertile scaffolds needed for bone to regenerate at the site of repair.
The researchers said these grafts could be used to promote swift and precise bone healing so that patients maximally benefit from the surgical intervention.
Researchers at the University of Maryland School of Medicine (UMSOM) evaluated several human antibodies to determine the most potent combination to be mixed in a cocktail and used as a promising anti-viral therapy against the virus that causes COVID-19. Their research, conducted in collaboration with scientists at Regeneron Pharmaceuticals, was published today in the journal Science.
The epigenome is sometimes referred to as the "software" or "operating system" of the genome. It comprises small chemical modifications to DNA and the proteins that make up our chromosomes, and controls the activity of all the genes within the genome.
Equity (or, its counterpart, inequity) plays a fundamental role in the evaluation of the different dimensions of social welfare. But how can we consider and compare its different dimensions? These issues are in fact traditionally considered and compared across individuals - be it within national boundaries or across countries, but also over time, when we consider the distribution of resources over time and the related questions of savings, intergenerational distribution stemming from capital dynamics or the intertemporal use of natural resources.
East Hanover, NJ. June 16, 2020. Experts in cognitive research evaluated the status of available treatments as well as promising strategies for treating cognitive deficits in multiple sclerosis. The article, "Treatment and management of cognitive dysfunction in patients with multiple sclerosis", was published in Nature Reviews 2020 May 05. (doi: 10.1038/s41582-020-0355-1) The authors are John DeLuca, PhD, and Nancy Chiaravalloti, PhD, of Kessler Foundation, and Brian Sandroff, PhD, of the University of Alabama at Birmingham.
Until there are effective treatments or vaccines, the COVID-19 pandemic will remain a significant threat to public health and economies around the world. A major hurdle to developing and testing new anti-viral therapies and vaccines for COVID-19 is the lack of good, widely available animal models of the disease.
