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…
These are the conclusions of research undertaken jointly by three Departments at the University of Navarra Hospital and which was published in the latest issue…
The researchers use stiff stilbene, a small, inert structure, as a molecular force probe to generate well-defined forces on various molecules, atom by atom.“By…
Their report was part of symposia that included almost two dozen papers at the 237th National Meeting of the American Chemical Society where scientists…
By reprogramming skin cells to an embryonic state using a plasmid rather than a virus to ferry reprogramming genes into adult cells, the Wisconsin group’s work…
The asexually produced babies mostly grow to be queen successors – so-called “secondary queens” – that remain in the termite colony and mate with the king….
At the same time they were able to shed light on the translocation process, which also plays a crucial role in cancer pathogenesis. During translocation,…
With pemphigus, the immune system attacks the organism: It attacks a group of proteins that is necessary for the cohesion of skin cells with antibodies. The…
“This disease can leave patients weak and on breathing machines, and conventional treatments can be toxic,” said Henry Kaminski, M.D., chair of the department…

Their new method, reported in the March 27 issue of the research journal Science, makes more of the body's chemistry visible by MRI, said Warren Warren, James…
Sepsis, an infection of the blood, can quickly overwhelm the body’s defenses and is responsible for more than 200,000 deaths per year in the U.S. alone. Premature newborns and people with weakened immune systems are especially vulnerable. Since most existing treatments are ineffective, researchers in the Vascular Biology Program at Children’s Hospital Boston have come up with a first line of defense — using magnetism to quickly pull pathogens out of the blood….
We cannot live without it; yet too much of it causes damage: oxygen is a critical component of many physiological and pathological processes in living cells. Oxygen deficiency in tissues is thus related to tumor growth, retinal damage from diabetes, and rheumatoid arthritis. It is thus important to determine the oxygen content of cells and tissues, which is a challenge to scientists. …
C. reinhartii, a common inhabitant of soils, naturally produces small quantities of hydrogen when deprived of oxygen. Like yeast and other microbes, under…
