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…
Many plants have evolved to endure harsh environmental conditions, yet the detailed mechanisms of plant stress resistance have long remained unclear. A single…
By combining this new microfluidic “droplet-on-demand” method with “optical tweezers” that could merge multiple droplets and cause their molecular contents to…
In cooperation with colleagues at The Johns Hopkins University, Dartmouth College, the University of Manitoba and two biopharmaceutical companies, the NIST…
The self-referencing optrode, developed in the lab of Marshall Porterfield, an associate professor of agricultural and biological engineering, is non-invasive,…
They found that the important proteins that make up the outer layer of these nanoparticles are degraded by an enzyme called cathepsin L. Scientists now have to…
The tools of biochemistry have finally caught up with lactose repressor protein. Biologists from Rice University in Houston and the University of Florence in…

“At present, the very best therapies we have for Parkinson's can only mask the symptoms – they do not alter the underlying disease,” said neurologist Dr. Katie…
Bone is continually recycled to maintain its strength through the competing action of osteoclasts, cells that break down aging bone, and osteoblasts, which…
While most women experience minor pain during menstruation, for others, the pain can be severe enough to interfere with everyday activities and require…
Beryllium, an exotic rare-earth metal used as a hardener in high-performance alloys and ceramics, can cause berylliosis—a chronic, incurable and sometimes…
In her dissertation at Kalmar University in Sweden, Ann Novotny has found that the signal molecule acetylcholine (ACh) is important for the progress of cancer…
Phlogiston theory was a conceptual breakthrough that helped chemists conduct experiments and share ideas. Only when it came to pinning down the distinctive…
To function normally, the cells that make up bodily tissues must “decide” when to divide and multiply (proliferate) and when to die. Cell death restricts the…
We now begin to understand how signalling proteins recognize and transport to certain areas of the cell and get a more clear insight on the mechanism of major…
