New limits to functional portion of human genome reported

An evolutionary biologist at the University of Houston has published new calculations that indicate no more than 25 percent of the human genome is functional. That is in stark contrast to suggestions by scientists with the ...

Small but mighty: Tiny proteins with big roles in biology (Update)

We all know how hard it is to find something small like a dropped contact lens that blends into the background. It's similarly tough for biologists to find tiny proteins against the complex background of the cell. But, increasingly, ...

Ethics review identifies top two challenges for genome editing

Preventing the transmission of inherited genetic diseases, and increasing food production rates in farmed animals are two potential applications of genome editing technologies that require urgent ethical scrutiny, according ...

Scientists develop new techniques to track how cells develop

Understanding how various cell types differentiate themselves during development is one of the fundamental questions in developmental biology. Using genome-editing tools, Harvard scientists are getting closer to finding answers.
