Peptide drugs with longer lifespan open new doors for treating diseases.

A research led by scientists from the University of the Pacific holds new possibilities for the treatment of cancer and other diseases using peptide drugs. The researchers concocted a technique to considerably enhance the lifespan of peptides such that they could be used more efficiently. Peptides are small chains of amino acids, the building blocks of proteins. Treating diseases like cancer by using peptides is thought to be effective because they can be more potent, and safer to use than large...

Building a brain from the inside out

Researchers at UC San Francisco have succeeded in mapping the genetic signature of a unique group of stem cells in the human brain that seem to generate most of the neurons in our massive cerebral cortex. The human cerebral cortex contains 16 billion neurons, wired together into arcane, layered circuits responsible for everything from our ability to walk and talk to our sense of nostalgia and drive to dream of the future. In the course of human evolution, the cortex has expanded as much as...
