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…
Autophagy refers to a fundamental recycling process of cells that occurs in yeast, fungi, plants, as well as animals and humans. This process allows cells to…
Environmental conditions like temperature, light, availability of nutrients and many other parameters are constantly changing on earth. Every organism and even…
Cell biologists traditionally use fluorescent dyes to label and visualize cells and the molecules within them under a microscope. With different…
In most cases, prostate cancer is cured by surgical removal of the tumour and/or by radiotherapy. However, 20% of patients will need treatment to remove tumour…
Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered how high glucose levels — whether…
Although their precise function in areas other than the mouth are not fully known, these sensory cells are thought to play an important “gatekeeper” role,…
Human skin is a remarkable organ serving as a barrier protecting us from pathogens, toxic substances and others. Our skin needs to constantly renew throughout…
Gases have been used throughout industry. Natural gas, for example, is “cracked” in refineries to make products like acetylene. The efficiency of gaseous…
In Switzerland, about 650 new cases of liver cancer are diagnosed every year. The incidence of the malignant and aggressive liver cell carcinoma has doubled in…
The researchers combined images from two specialised sensors mounted in airplanes to evaluate the density and colour of leaves on individual trees in the city…
For decades, scientists have been trying to make a true molecular chain: a repeated set of tiny rings interlocked together. In a study in Science published…
Misfolded proteins are non-functional and cause cell damage. In order to prevent this, there is a whole arsenal of proteins – called chaperones – that assist…
Archimedes envisioned that a network structure – a polygon made by triangles – created by sampling the geometrical law of a circle, is a useful device to…
In a new study, researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory, Tufts University and Oak Ridge National Laboratory teamed up…
One of the first analogies that people learn when studying biology is that the specific interaction of proteins is like a lock and key. The 3D shape of the…
Viruses encapsulate their genetic material in a shell comprising a series of identical protein building blocks. The hepatitis B virus capsule, for example,…
