Astronomers provide fresh peek at nearby galaxy

An international team of astronomers, including scientists at the University of Wisconsin-Madison, has created two striking images of the Large Magellanic Cloud (LMC), a small galaxy nestled right next to the Milky Way.

Gold Nanoparticles Prove to Be Hot Stuff

Gold nanoparticles are highly efficient and sensitive “handles” for biological molecules being manipulated and tracked by lasers, but they also can heat up fast—by tens of degrees in just a few nanoseconds—which could ...

Nano-Signals Get a Boost from Magnetic Spin Waves

Researchers have figured out how nanoscale microwave transmitters gain greater signal power than the sum of their parts—a finding that will help in the design of nano-oscillator arrays for possible use as transmitters and ...

Study Solves Ocean Plant Mystery

A NASA-sponsored study shows that by using a new technique, scientists can determine what limits the growth of ocean algae, or phytoplankton, and how this affects Earth's climate.
