Getting enough vitamin B12 to meet current health guidelines may not actually be enough to protect the aging brain.
MIT researchers have discovered that a naturally occurring amino acid found in many protein-rich foods may help the intestine repair itself after damage. Cysteine has long been known for its antioxidant properties, but this is the first study showing that it can directly stimulate intestinal stem cell regeneration. Researchers are also continuing to investigate the effects of other amino acids that showed signs of influencing stem cell behavior.
A new nanotechnology treatment reversed Alzheimer’s symptoms in mice by restoring the brain’s natural cleanup system.
A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers stumbled upon a bizarre genetic code in a microscopic pond organism.
Scientists at Stellenbosch University (SU) have uncovered the first evidence of a rare group of phenolic compounds known as flavoalkaloids in Cannabis leaves, adding a surprising new dimension to the plant's chemistry. In their study, researchers analyzed three commercially grown Cannabis strains from South Africa and identified 79 phenolic compounds. André de Villiers, who led the study and heads the analytical chemistry research group at SU, said the results were striking.
A large study published in The BMJ suggests that aerobic activities such as walking, cycling, and swimming are the most effective exercises for people with knee osteoarthritis. Researchers note that while other types of exercise can still help, they should be used alongside aerobic activity rather than replacing it as the primary approach. Based on the results, the researchers recommend aerobic exercise "as a first line intervention for knee osteoarthritis management, particularly when the aim is to improve functional capacity and reduce pain."
After two centuries of failed attempts, scientists have finally grown dolomite in the lab, cracking a long-standing geological puzzle.
The ozone layer has been on track to recover thanks to the Montreal Protocol—but a loophole may be holding it back. Chemicals still permitted for industrial use are leaking into the atmosphere at higher rates than expected.
