Researchers have discovered a previously unknown reason for drug resistance in a common subtype of melanoma, one of the deadliest forms of cancer, and in turn, have found a new therapy that could prevent or reverse drug resistance for melanoma patients with a particular gene mutation.READ MORE
Columbia University biomedical researchers have captured close-up views of TRPV3, a skin-cell ion channel that plays important roles in sensing temperature, itch, and pain. Researchers think that changes in the TRPV3 genes of mammoths may have helped them withstand lower temperatures.
A large-scale genetic study found that some of the same genes associated with the use of cannabis are also associated with certain personality types and psychiatric conditions.
