An artificial eclipse for imaging extrasolar planets

As anyone anticipating this month’s eclipse knows, one way to dim a star is to block it with something else – a moon, perhaps. Or in the case of distant stars whose light masks orbiting exoplanets, a shade-throwing satellite might do.

Manmade and natural earthquakes share shaking potential

New research shows manmade and naturally occurring earthquakes in the central U.S. share the same characteristics, information that will help scientists predict and mitigate damage from future earthquakes.

Evidence for a particle that is its own antiparticle

In a discovery that concludes an 80-year quest, Stanford and University of California researchers found evidence of particles that are their own antiparticles. These Majorana fermions  could one day help make quantum computers more robust.

Tuna fin movement controlled by biological hydraulic systems

The unique system of hydraulic control of fins discovered in tuna indicates a new role for the lymphatic system in vertebrates. This natural mechanism may inspire designs for new “smart” control surfaces with changeable shape and stiffness for both air and underwater unmanned vehicles.
