Interface engineering for stable perovskite solar cells

The lifetime of perovskite solar cells is significantly enhanced by using few-layer molybdenum disulphide (MoS2) flakes as an active buffer interface layer. Researchers from the Graphene Flagship show that interface engineering ...

Watching apoptosis in 3D

A promising approach for watching cell signaling processes in their physiological context: Scientists visualize apoptosis in live zebrafish using fluorescence lifetime imaging with optical projection tomography to map FRET ...

Biomedical imaging at one-thousandth the cost

MIT researchers have developed a biomedical imaging system that could ultimately replace a $100,000 piece of a lab equipment with components that cost just hundreds of dollars.

Gravity, who needs it? NASA studies your body in space

What happens to your body in space? NASA's Human Research Program has been unfolding answers for over a decade. Space is a dangerous, unfriendly place. Isolated from family and friends, exposed to radiation that could increase ...

Team extends the lifetime of atoms using a mirror

Researchers at Chalmers University of Technology have succeeded in an experiment where they get an artificial atom to survive ten times longer than normal by positioning the atom in front of a mirror. The findings were recently ...

Study gives more accurate picture of value of college education

A new study that is the first to use Social Security Administration's personal income tax data tracking the same individuals over 20 years to measure individual lifetime earnings has confirmed significant long-term economic ...

Fracking may affect air quality and human health

People living or working near active natural gas wells may be exposed to certain pollutants at higher levels than the Environmental Protection Agency considers safe for lifetime exposure, according to scientists from Oregon ...
