How does a zebrafish grow a new tail?

...have discovered some of the genes and cell-to-cell communication pathways that enable zebrafish to restore their tail fins. "The ability to regenerate body parts such as those that are damaged by injury or disease," said Dr. Randall Moon, professor of pharmacology at the University of Washington (UW), an investig...

Protein's effects essential for kidney-to-bladder urine transfer

...Immunobiology, the immune synapse is a specialized communication structure created by two immune cells. According to the theory, this communication activates immune cells to fight invaders. Swat had hypothesized that DLGH1 might help move structure...

Research yields new insights into the cause of diabetes

...e beta cells. But without the islet architecture, communication among the beta cells breaks down and the cells fail to respond to glucose by secreting insulin. Thus, PERK-deficiency both hampers cell-to-cell signaling of glucose levels and greatly diminishes insulin production at the cellular level. The Penn St...

Cities change the songs of birds

...s that some aspects of the vocal variety of animal communication sounds are shaped by the environment. The authors point out that song divergence within a species as a result of such environmental shaping could potentially play a crucial role in the process of speciation, although it is not at all clear whether ur...

NJIT women scientists and engineers use new information technologies to tackle isolation on campus

Protein shown to rally biological clock

...r. Together these neurons are intrinsic clocks in communication with each other to keep 24-hour time. It had been thought that GABA was the prime candidate for the rallying role. All SCN neurons make this inhibitory neurotransmitter, and it had been shown that giving GABA daily at 8 a.m. to SCN cells synchroni...
