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…
The results, which appear in the March 2009 issue of Experimental Biology and Medicine, implicate PAI-1 overexpression, known to accompany insulin resistance…
Working with mice, they found that a molecule called an adenosine receptor is necessary for sleep-restricted animals to attain adequate levels of slow-wave…
New research, published in the journal PLoS One (on Wednesday 25 February 2009), explains how this curious behaviour can be predicted by adapting models more…
Two-component signal transduction systems (TCSTs) have long been recognised as the main way in which bacteria coordinate their responses to changes in their…
A study published today (Wednesday 25 February 2009) shows it is possible to predict how fast a population will spread and reveals the importance of habitat…
As with any control system, noise – errors, slip-ups, mis-reads – can get in the way of correct decision making. Virginia Tech biologists and engineers have…
McGill University chemistry professor Chao-Jun (C.J.) Li is known as one of the world leading pioneers in green chemistry, an entirely new approach to the…
Plant stem-cells are master cells located at the tip of the stem and are part of a structure called the shoot apical meristem (SAM). Here, the stem cells—all…
Psychedelica is perhaps even more apt given the cockamamie way the fish swim, some with so little control they look intoxicated and should be cited for DUI.Members of Histiophryne psychedelica, or H. psychedelica, don't so much swim as hop. Each time they strike the seafloor they use their fins to push off and they expel water from tiny gill openings on their sides to jettison themselves forward. With tails curled tightly to one side –which surely limits their ability to steer – they look like inflated rubber balls bouncing hither and thither….
The finding in an animal study suggests that blocking this gene could one day be a therapeutic strategy to reduce diet-related obesity and associated…
“The results were just stunning, absolutely amazing,” said Richard B. Silverman, John Evans Professor of Chemistry in the Weinberg College of Arts and Sciences…

Paradoxically, the same compound also may reduce pain. Capsaicin creams are natural pain-relieving folk medicines, commonly found over the counter, and are…
Researchers have found a way to block the ability of white blood cells to sprint toward the sites of infection when such speed worsens the damage done by…
Some of the causes might include personal history of depression, stressful life events, and lack of social, financial or emotional support. Left untreated, it…
