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…
Some cancers, like breast and prostate cancer, are driven by hormones such as estrogen and testosterone, but to date, there are none that are driven by the…

In 1995, 16-month old Kumari, the first Asian elephant born at the National Zoo in Washington, DC, died of a then-mysterious illness. In 1999, Gary Hayward of…
Biological evolution is in general based on the progressive adaption of traits through natural or sexual selection. However, ever so often, complex traits with…
A new discovery suggests that the number of human genomic loci that might be coding for tRNAs is nearly double what is currently known. Most of the newly…
A team of ETH Zurich researchers led by professors Nenad Ban and Ruedi Aebersold have studied the highly complex molecular structure of mitoribosomes, which are the ribosomes of mitochondria. Ribosomes are found in the cells of all living organisms. However, higher organisms (eukaryotes), which include fungi, plants, animals and humans, contain much more complex ribosomes than bacteria. In eukaryotes, ribosomes can also be divided into two types: those in the cytosol – which comprises the majority of the cell –…
The researchers found that giving this new fat, or lipid, to mice with the equivalent of type 2 diabetes lowered their elevated blood sugar, as detailed…
The introduction of foreign DNA into human cells through a process known as ‘transfection’ allows scientists to study gene expression in the laboratory and…
