Delivering Genes Across the Blood-Brain Barrier

Caltech biologists have modified a harmless virus in such a way that it can successfully enter the adult mouse brain through the bloodstream and deliver genes to cells of the nervous system. The virus could help researchers map the intricacies of the brain and holds...

White House Puts Spotlight on Earthquake Early-Warning System

Since the late 1970s, Caltech seismologist Tom Heaton, professor of engineering seismology, has been working to develop earthquake early-warning (EEW) systems—networks of ground-based sensors that can send data to users when the earth begins to tremble nearby, giving...

Realizing your true (solar) potential

Nations worldwide are increasingly embracing solar power as an alternative electricity source for homes, buildings, and even the grid. Since 2008, installed solar capacity in the United States alone has grown 17-fold, from 1.2 to 20 gigawatts (GW), according to the...

A new-generation exoskeleton helps the paralyzed to walk

Graphene is strong, but is it tough?

Graphene, a material consisting of a single layer of carbon atoms, has been touted as the strongest material known to exist, 200 times stronger than steel, lighter than paper, and with extraordinary mechanical and electrical properties. But can it live up to its...

New Galaxy-hunting Sky Camera Sees Redder Better

A newly upgraded camera that incorporates light sensors developed at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) is now one of the best cameras on the planet for studying outer space at red wavelengths that are too red for the...
