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…
New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to…
Two University of Alberta researchers and a colleague from Sweden have found some answers to that question in three different studies on expectations for…
In a study conducted at the University of Idaho, scientists found that the immune system of the study’s frog species failed to respond to the chytrid fungus…
The REDD1 protein is a critical inhibitor of the mTOR signaling pathway, which controls cell growth and proliferation. The study was published in the August…
Scientists at Imperial College London have created detailed 3D computer models of two fossilised specimens of ancient creatures called Cryptomartus hindi and Eophrynus prestvicii, closely related to modern-day spiders. The study reveals some of the physical traits that helped them to hunt for prey and evade predators. The researchers created their images by using a CT scanning device, which enabled them to take 3,000 x-rays of each fossil. These x-rays were then compiled into precise 3D models, using custom-designed software….
To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. A gas flows easily out of a tank, but getting hydrogen out of a molecule requires a catalyst. Now, researchers reveal new details about one such catalyst. The results are a step toward designing catalysts for use in hydrogen energy applications such as fuel cells. Scientists from the Department of Energy's Pacific Northwest National…
It is important to understand what biological mechanisms contribute to an individual's capacity to be resilient under conditions of extreme stress, such as…
The study, the cover story in the Aug. 6, 2009, issue of the journal Nature, also opens the door for further research which could accelerate the development of…
The results of this research project, which was initiated in 2005 and is supported by Bizkaia:Xede and the Basque Government's Etortek programme, were…
Pyruvate carboxylase is a metabolic enzyme that plays a fundamental role in the metabolism of fatty acids (the components of fats) and sugars. When its…
The genetic information was obtained using pyrosequencing technology in the Keck Center at the U of I. The genetic sequence will allow scientists to study…
In 1957, shepherds in Idaho (USA) discovered that when pregnant sheep ate lilies of the species Veratrum californicum (corn lily, California false hellebore),…
Effective response by key immune cells in the body, called T cells, is crucial for control of many widespread chronic viral infections such as HIV and…
While banded birds are sometimes seen in the area where they were originally released, it is very rare to see them so far from a release site.The observation…
The data may help stem cell researchers understand the mechanisms that determine whether stem cells divide or differentiate, what types of cells they become…
