New study reveals how human astroviruses bind to humans cells and paves the way for new therapies and vaccines Human astroviruses are a leading viral cause of the stomach bug—think vomiting, diarrhea, and fever. It often impacts young children and older adults, leading to vicious cycles of sickness and malnutrition, particularly for those in low and middle income countries. It’s very commonly found in wastewater studies, meaning it’s frequently circulating in communities. As of now, there are no vaccines for…
Most of us know what it means when it's said that someone is depressed. But commonly, true clinical depression brings with it a number of other symptoms. These…
In this study which was performed in lab animals, researchers found that fructose can be metabolized by an enzyme that exists in two forms. One form appears to…
TAK-875, a new treatment for type 2 diabetes, improves blood sugar control and is equally effective as glimepiride, but has a significantly lower risk of…
Cancer cells that break free from a tumor and circulate through the bloodstream spread cancer to other parts of the body. But this process, called metastasis,…
In structural biology these include proteins, enzymes and viruses. A single change in their molecular structure can mean the difference between function and…
Researchers have identified an elusive gene responsible for Thrombocytopenia with Absent Radii (TAR), a rare inherited blood and skeletal disorder. As a…
For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and…
One of the first large-scale genomic studies conducted in a developing country has discovered genetic variants that elevate the risk for skin lesions in people…
Even though typical dance-floor activity might suggest otherwise, humans generally demonstrate a remarkable capacity to synchronize their body movements in…
They found that specific neurons in a brain region called the dentate gyrus serve distinct roles in memory formation depending on whether the neural stem cells…
Not all that glitters is gold. Sometimes it is just bacteria trying to get ahead in life. Many sea creatures glow with a biologically produced light. This…
Physical oceanographers and marine chemists at the Leibniz Institute for Baltic Sea Research in Warnemünde returned from their latest monitoring cruise (2-14…
The work, reported this week in the online Nature Communications, is a step toward biomedical devices with active components made from nanostructured systems.LEDs based on solution-processed inorganic nanocrystals have promise for use in environmental and biomedical diagnostics, because they are cheap to produce, robust, and chemically stable. But development has been hampered by the difficulty of achieving ultraviolet emission. In their paper, Los Alamos National Laboratory's Sergio Brovelli in collaboration with the research team lead by Alberto Paleari at the University of Milano-Bicocca in Italy describe a fabrication process that overcomes this problem and opens the way for integration in a variety of applications….
Some, for example, have syringe-like exterior structures that can pierce other cells and inject proteins. Another system, called a type VI secretion system, is…
For the past decade, scientists have been pursuing cancer treatments based on RNA interference — a phenomenon that offers a way to shut off malfunctioning…
In the current issue of Nature Neuroscience, they therefore rule out a popular hypothesis on the origins of MS. The scientists are now primarily looking for…
