FDA-approved epilepsy drug may help reverse osteoarthritis damage
Researchers at Yale have identified a promising new approach to osteoarthritis that could do more than simply ease pain. The epilepsy drug lacosamide appears to block a protein involved in both pain signaling and cartilage destruction, helping damaged joints shift back toward repair in preclinical studies.
Scientists accidentally discover a genetic code that breaks the rules of life
Scientists accidentally discovered a microscopic organism with a genetic code that breaks a rule researchers thought was nearly universal. While testing a new DNA sequencing technique, they examined a previously unknown protist collected from a freshwater pond at Oxford University. To their surprise, the organism uses two genetic signals that normally mark the end of a gene to encode two entirely different amino acids instead. These signals were previously thought to evolve together, making the discovery particularly remarkable.
This “golden tree” coral was too strange for any known family
A brilliant yellow coral discovered off Costa Rica proved so unusual that scientists had to create an entirely new family to classify it. The meter-tall colonies rise from seafloors covered in brittle stars, inspiring the Tolkien-inspired name Laurinque elenya, or “golden tree of the stars.” Advanced genetic analysis revealed that the coral belongs to a previously unknown evolutionary lineage.
