Glow-in-the-dark zebrafish at UH hold keys to biological clocks

... slow, providing the ability to trace the specific genes that create the anomaly. Putting UH a bit ahead of other institutions engaged in this type of research, Cahill and his team will be able to analyze more than 2,000 zebrafish per week. The per3-luc zebrafish is the first vertebrate system available fo...

New lab technique identifies high levels of pathogens in therapy pool

Scientists identify genetic pathways essential to RNA interference

...setts General Hospital (MGH) has identified 80 new genes essential to the process of RNA interference (RNAi), a powerful new research tool for inactivating genes in plants or animals. They used the RNAi process itself to find new genes that participate in the ge...

Revolutionary nanotechnology illuminates brain cells at work
