Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in mice reveals an unexpected cause: Stem cells in aged muscle accumulate higher levels of a protein that slows their…

Cells can generate negative viscosity to propel movement
The cells in our bodies move in groups during biological processes such as wound healing and tissue development – but because of resistance, or viscosity, those cells can’t just neatly glide past each other.
Or can they?
Using a…

New species of ladybird beetle discovered on university campus in Japan
University campuses are often places of learning and discovery, but rarely do researchers find a new species living right on their doorstep. However, that is exactly what happened when a research team from Kyushu University discovered a new…

Fossil hunters uncover 132-million-year-old dinosaur footprints on South Africa's coast
Southern Africa is world renowned for its fossil record of creatures that lived in the very distant past, including dinosaurs. But, about 182 million years ago, a huge eruption of lava covered much of the landscape (the inland Karoo Basin) where…

Ashwagandha is having a moment—researchers want to take this shrub further
Ashwagandha is a small shrub that’s having a big moment. Used in traditional Indian medicine for thousands of years, ashwagandha is now one of the most popular herbal supplements in the U.S. because of its professed benefits for sleep and stress….

A world-first mouse that makes gene activity visible
DNA can be thought of as a vast library that stores all genetic information. Cells do not use this information all at once. Instead, they copy only the necessary parts into RNA, which is then used to produce proteins—the essential building…

Genetic ancestry influences tumor biology and survival in head and neck cancers
Genetic ancestry plays a key role in determining the behavior of head and neck tumors and may help explain why African-American patients survive for half as long as their counterparts of European ancestry, according to a new review…

'Negative viscosity' helps propel groups of migrating cells, study finds
The cells in our bodies move in groups during biological processes such as wound healing and tissue development—but because of resistance, or viscosity, those cells can’t just neatly glide past each other.

Scientists uncover new mechanism initiating gene transcription
Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) into…
