Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories’ Z machine have been able to determine experimentally, for the first time in history, iron’s role in inhibiting energy transmission from the center of the sun to near the edge of its radiative band — the section of the solar interior between the sun’s core and outer convection zone.

University of Delaware researcher Jonathan Cohen is using a new technology to analyze and quantify zooplankton in the Delaware Bay.

Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis. The study, of soil from Syria, is the latest to discredit the controversial theory that a cosmic impact triggered the Younger Dryas cold period.

From new insights into the building blocks of matter to advances in understanding batteries, superconductors, and a protein that could help fight cancer, 2014 was a year of stunning successes for the U.S. Department of Energy's Brookhaven National Laboratory. Oh, and did we mention the opening of a brand new facility that will push the limits of discovery across the scientific spectrum? For details on these and the rest of our Top-10 breakthroughs, check out the items below. You can follow Brookhaven Lab on Facebook, Twitter, and Tumblr to learn about the discoveries of 2015 as they happen.

In what they call a “weird little corner” of the already weird world of neutrinos, physicists have found evidence that these tiny particles might be involved in a surprising reaction.

Rust never sleeps. Whether a reference to the 1979 Neil Young album or a product designed to protect metal surfaces, the phrase invokes the idea that corrosion from oxidation—the more general chemical name for rust and other reactions of metal with oxygen—is an inevitable, persistent process. But a new study performed at the Center for Functional Nanomaterials (CFN) at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory reveals that certain features of metal surfaces can stop the process of oxidation in its tracks.

The world owes a debt of gratitude to Simon Fraser University (SFU) biologist Regine Gries. Her arms have provided a blood meal for more than a thousand bedbugs each week for five years while she and her husband, biology professor Gerhard Gries, searched for a way to conquer the global bedbug epidemic.

Innovative optical fiber developed by researchers from Clemson University, the University of Wisconsin-Milwaukee, the University of New Mexico and Corning Incorporated was chosen as one of Physics World’s Top Ten Breakthroughs of 2014.
