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…
A new study in Nature Medicine describes how different types of immune system T-cells alternately discourage and encourage stem cells to regrow bone and…
Most liquid-crystalline displays contain rod-like molecules that quickly switch from one orientation to another when subjected to electric fields. This…
Researchers in Japan have solved the structure of a complex between the antihistamine drug doxepin and its target receptor histamine H1 receptor (H1R)1. Led by…
In a study published in the Nov. 17, 2011 issue of PLoS Genetics, they demonstrate that a protein known as Mps3 not only ensures that cells have two functional…
But now an international team of scientists led by Serena DeBeer, Cornell assistant professor of chemistry and chemical biology, has pulled back the curtain…
When released extracellular vesicles can affect tumor spread, blood clotting and inflammation. Their discovery gives new insight into how extracellular…
Lasioglossum gotham is one of 11 new bees discovered in the Eastern U.S. It earned its “Gotham” tag because it is one of four found living in New York City and…

Promising results of a phase 2 trial of dexpramipexole are receiving advance online publication in Nature Medicine. Some preliminary results of the study were…
Similarly, when a newly created drug doesn’t bind well to its intended target, the drug won’t work. Scientists are then forced to go back to the lab, often…
Why do people with a hereditary mutation of the red blood pigment hemoglobin (as is the case with sickle-cell anemia prevalent in Africa) not contract severe…
Many infections, even those caused by antibiotic-sensitive bacteria, resist treatment. This paradox has vexed physicians for decades, and makes some infections…
A University of Louisville scientist has determined for the first time how the bacterium that causes Legionnaires’ disease manipulates our cells to generate…
Dendrimers have been used to encapsulate drug molecules and serve as a delivery vehicle, but in the new study they were employed to capture circulating tumor…
The findings are reported by a scientist from UC Santa Barbara and a research team from Harvard University in the Proceedings of the Royal Society B this week.Columbine flowers, known as Aquilegia, evolved several lengths of petal spurs that match the tongue lengths of their pollinators, including bees, hummingbirds, and hawkmoths. The petal spurs are shaped like a tubular pocket and contain nectar at the tip. The spurs grow from 1 to 16 centimeters in length, depending on the species….
