At last, how many alien civilizations are there?

During the space age, 1961 was a special year: the Russian cosmonaut Yuri Gagarin became the first man to orbit Earth, while the American astronomer Frank Drake developed the now famous Drake Equation. This equation estimates ...

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 ...

Weak nuclear force is less weak

The force that governs some of the reactions that keep our sun shining is not quite as weak as scientists had previously thought. As a consequence, our estimation of how energetic the sun actually is just went up by a tiny ...

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 ...

Scientists break light modulation speed record -- twice

Researchers have constructed a light-emitting transistor that has set a new record with a signal-processing modulation speed of 4.3 gigahertz, breaking the previous record of 1.7 gigahertz held by a light-emitting diode.

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 ...

New bioimaging technique is fast and economical

A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue—such as an organ or a small animal; technology that could have applications ...

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.
