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 cleavage product of the Alzheimer's APP protein stimulates nerve cell communication and memory. The protein fragment, known as APPsα, has neuroprotective…
Climate change could speed the natural regrowth of forests on undeveloped or abandoned land in the eastern U.S., according to a new study.
“We have managed to couple two origami filaments and to move them apart in a controlled fashion. We call this filament sliding. By doing so, we have imitated,…
In the fight against cancer, scientists are developing new drugs to hit tumor cells at so far unused weak points. Such a “sore spot” is the protein complex…
Our brain’s capacity to learn and to form memories relies on the ability to respond adaptively to environmental inputs. The integration of these inputs occurs…
In the pre-industrial age, twilight was a dangerous time for humans since they were at risk of encountering nocturnal predators. Anyone still able to recognise…
A new study by Swansea University and Deakin University academics, published in the recent Marine Pollution Bulletin, reported how the monitoring of the…
Decades have been spent investigating how cancer cells manage to reproduce while evading the control of the immune system. So-called immunotherapies are…
Interactions between organisms such as plants and animals can be found everywhere in nature. Anina Knauer and Florian Schiestl, a professor at UZH’s Department…
Nanomachines include structures of complex proteins and nucleic acids that are powered with chemical energy and can perform directed movements. The principle…
If on a warm summer's evening in the beer garden, small beetles dive into your beer, consider giving them a break. Referred to as “ambrosia beetles”, these…
All bacteria have a standard secretion system that allows them to export different types of proteins outside of their cells. An important class of…
Our seas are not everywhere fertile and full of colourful, diverse life. Wide areas of the world's oceans are naturally poor in nutrients. The fact that marine…
Some animals, such as the axolotl salamander, can regrow new body parts in a process that involves the generation of new cells. The damaged cells will die off…
Current seasonal influenza vaccines mainly target a different, more abundant influenza surface protein called hemagglutinin (HA). However, because influenza…
In the same way that a body contains functional organs, every cell contains functional organelles, each with a specific task. In the cell different organelles…
