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…
Staphylococcus aureus bacteria are a major cause of serious infections that often persist despite antibiotic treatment, but scientists at the UNC School of…
Researchers at University of California San Diego School of Medicine recently found that removing the enzyme PHLPP1 improved outcomes in a mouse model of…
The mechanisms by which new species arise are still not fully understood. What are the evolutionary processes that drive the evolution of new species?…
Rice University scientists have found a way to engineer a new kind of cell differentiation in bacteria, inspired by a naturally occurring process in stem cells.
Many diseases occur because a person’s DNA contains errors, so-called mutations. These cause vital protein molecules to be produced incorrectly. Sometimes the…
Their paper, published today in the journal Nature Materials, explains why these detergents, called ionic liquids, are better electrolytes than current…
Each year, more than 200,000 people receive a prosthetic hip in Germany. The success of these operations has a major impact on the quality of life of those…
Recycling is also a vital process in the cells of the human body. Using the process known as autophagy, cells break down defective and therefore potentially…
Based on insights from studying basic mechanisms of gene regulation and human hereditary diseases, it was previously assumed that the three-dimensional…
The brains of Alzheimer's patients who have already developed clinical symptoms contain large clumps of the protein beta-amyloid, known as plaques. Many…
You know you have a skeleton, but did you know that your cells have skeletons, too? Cellular skeletons, or cytoskeletons, are shapeshifting networks of tiny…
Most people with a medical condition called long QT syndrome have a mutation in a gene that causes bouts of fast, chaotic heartbeats. They also experience…
After an egg is fertilized, it begins to divide and passes through several stages. Cells in the two-cell stage are totipotent–they can become any type of…
Stem cells hold the key to wound healing, as they develop into specialised cell types throughout the body – including in teeth.
It is commonly accepted that neurons of the central nervous system shut down their ability to grow when they no longer need it; this occurs normally after they…
The splitting of two water molecules into oxygen using sunlight is the first step of photosynthesis, a process performed by plants and cyanobacteria. The…
