Johns Hopkins biomedical engineers, working with colleagues in Korea, have produced a laboratory chip with nanoscopic grooves and ridges capable of growing cardiac tissue that more closely resembles natural heart muscle. Surprisingly, heart cells cultured in this way used a “nanosense” to collect instructions for growth and function solely from the physical patterns on the [...]

A team led by researchers at Albert Einstein College of Medicine of Yeshiva University has found a clear link between living to 100 and inheriting a hyperactive version of an enzyme that rebuilds telomeres – the tip ends of chromosomes. The findings appear in the latest issue of the Proceedings of the National Academy of [...]

Researchers from Boston University School of Medicine (BUSM) have shown that intermittent access to foods rich in fat and sugar induces changes in the brain which are comparable to those observed in drug dependence. The findings, reported in the journal Proceedings of the National Academy of Sciences, may explain how abstinence from these foods contributes [...]

Age-related hearing loss is the most common sensory disorder among the elderly. But scientists are still trying to figure out what cellular processes govern or contribute to the loss.
Now a University of Florida team and researchers from University of Wisconsin and three other institutions have identified a protein that is central to processes that cause [...]

A compound already used to treat pneumonia could become a new therapy for an inherited muscular wasting disease, according to researchers at the University of Oregon and the University of Rochester School of Medicine and Dentistry in New York.
