A newly discovered genetic clock acts as the body’s developmental timekeeper, coordinating the bursts of gene activity needed for growth. Scientists found that when this clock breaks down, development comes to a halt. Think about a train sitting at a station. Passengers have boarded, conductors are checking tickets, and everything is ready to go. But [...]

Detached sea cucumber tissue survived, healed, and grew for years in natural seawater, revealing a remarkable new model for regeneration and biomedical research. A chance observation has led scientists to a discovery that challenges one of biology’s most basic assumptions: that detached animal tissue eventually dies. Instead, researchers found that tissue removed from a sea [...]

A new study suggests that reproducing a crucial sleep-like brain pattern in awake animals may help preserve memory and learning abilities. What if part of the brain could get some of the benefits of sleep without the rest of the brain ever going offline? A new NIH-funded study suggests that may be possible. Researchers found [...]

A newly identified vitamin K-dependent signaling pathway appears to help coordinate communication between key bone cells. Bones may seem like lifeless structures, but they are constantly being torn down and rebuilt. Every day, specialized cells remove old bone while others replace it with new material, a process that keeps the skeleton strong and adaptable throughout [...]
