Satellites orbiting the Earth must occasionally be nudged to stay on the
correct path. MIT scientists are developing a new rocket that could make this
and other spacecraft maneuvers much less costly, a consideration of growing
importance as...

Countless hours are lost in traffic jams every year. Most frustrating of all are those jams with no apparent cause -- no accident, no stalled vehicle, no lanes closed for construction.
Such phantom jams can form when there is a heavy volume of...

A new light-bending material has brought scientists one step closer to creating
a cloaking device that could hide objects from sight.
Beyond possible military applications, it also might have a very practical use
by making mobile...

A device that can bestow invisibility to an object by "cloaking" it from visual light is closer to reality. After being the first to demonstrate the feasibility of such a device by constructing a prototype in 2006, a team of Duke University...

A new approach is able to create a dramatic improvement in
cheap solar cells now being developed in laboratories. By using a popcorn-ball
design -- tiny kernels clumped into much larger porous spheres -- researchers at
the...

There’s a strange wave phenomenon that’s plagued rocket
scientists for years, a lurking threat with the power to destroy an engine at
almost any time. For decades, scientists have had a limited understanding of how
or why...

A new 11-year cycle of heightened solar activity, bringing with it increased
risks for power grids, critical military, civilian and airline communications,
GPS signals and even cell phones and ATM transactions, showed signs it was on
