What do they mean by 'stem cells'? Recommended guidelines for reporting on cell therapies

Cell therapies including so-called "stem cells" are increasingly being marketed and used for the treatment of musculoskeletal disorders - despite questions about these treatments and their effectiveness. A new tool for standardizing communication about cell therapies is presented in the May 15 issue of The Journal of Bone & Joint Surgery.

Scientists find new type of cell that helps tadpoles' tails regenerate

Researchers at the University of Cambridge have uncovered a specialised population of skin cells that coordinate tail regeneration in frogs. These 'Regeneration-Organizing Cells' help to explain one of the great mysteries of nature and may offer clues about how this ability might be achieved in mammalian tissues.

Could better tests help reverse the rise of drug-resistant infections?

A growing number of infections—such as pneumonia, gonorrhea and tuberculosis—are becoming harder to treat, as bacteria evolve defenses against antibiotics faster than we can develop new drugs to replace them.

A simplified method to categorize olive oil

Olive oil classification is currently very costly and slow. In order to categorize oil into extra virgin (EVOO), virgin (VOO) and lampante olive oil (LOO), an offical method is used, consisting of a physicochemical analysis and a sensory analysis in the end. This last part is based on the work of a panel of expert tasters who try each olive oil one by one in order to determine its category. This process is very costly for the bottlers. For this reason, they are keen on developing a complementary analytical classification method. Moreover, there are very few expert olive oil tasters in other countries, hence the urgency to find another way to categorize olive oil that does not involve sensory analysis.

Miro2 is a Parkin receptor for selective removal of damaged mitochondria

Mitophagy plays a central role in the mitochondrial quality control system, and defective mitophagy is linked to a variety of human diseases. At present, how the damaged mitochondria are selectively recognized and removed to ensure the accuracy of mitophagic clearance remains unclear.

Experimental brain-controlled hearing aid decodes, identifies who you want to hear

Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing aids struggle to do. But now Columbia engineers are announcing an experimental technology that mimics the brain's natural aptitude for detecting and amplifying any one voice from many. Powered by artificial intelligence, this brain-controlled hearing aid acts as an automatic filter, monitoring wearers' brain waves and boosting the voice they want to focus on.
