Scientists deepen understanding of the magnetic fields that surround the Earth and other planets
Princeton Plasma Physics Laboratory

Now, a team of scientists has completed research into waves that travel through the magnetosphere, deepening understanding of the region and its interaction with our own planet, and opening up new ways to study other planets across the galaxy.

Light dark matter is a thousand times less likely to bump into regular matter than previous astrophysical analyses allowed
SLAC National Accelerator Laboratory

A team led by scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University has narrowed down how strongly dark matter particles might interact with normal matter. Based on the number and distribution of small satellite galaxies seen orbiting our Milky Way, the team found this interaction to be at least a thousand times weaker than the strongest interaction allowed by previous astrophysical analyses.

Newswise: New Sensor Could Shake Up Earthquake Response Efforts

New Sensor Could Shake Up Earthquake Response Efforts
Lawrence Berkeley National Laboratory

An optical sensor developed at Berkeley Lab could speed up the time it takes to evaluate whether buildings are safe to occupy after a major earthquake. After four years of extensive peer-reviewed research and simulative testing at the University of Nevada’s Earthquake Engineering Laboratory, the Discrete Diode Position Sensor (DDPS) will be deployed for the first time this summer in a multi-story building at Berkeley Lab – which sits adjacent to the Hayward Fault, considered one of the most dangerous faults in the United States.

The best of both worlds: how to solve real problems on modern quantum computers
Argonne National Laboratory

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Los Alamos National Laboratory, along with researchers at Clemson University and Fujitsu Laboratories of America, have developed hybrid algorithms to run on size-limited quantum machines and have demonstrated them for practical applications.

Designer proteins form wires and lattices on mineral surface
Pacific Northwest National Laboratory

This research is a fundamental discovery of how to engineer proteins onto non-biological surfaces. Artificial proteins engineered from scratch have been assembled into nanorod arrays, designer filaments and honeycomb lattices on the surface of mica, demonstrating control over the way proteins interact with surfaces to form complex structures previously seen only in natural protein systems. The study provides a foundation for understanding how protein-crystal interactions can be systematically programmed and sets the stage for designing novel protein-inorganic hybrid materials.

Newswise: Giving nanowires a DNA-like twist

Giving nanowires a DNA-like twist
Argonne National Laboratory

Argonne National Laboratory played a critical role in the discovery of a DNA-like twisted crystal structure created with a germanium sulfide nanowire, also known as a “van der Waals material.” Researchers can tailor these nanowires in many different ways — twist periods from two to twenty micrometers, lengths up to hundreds of micrometers, and radial dimensions from several hundred nanometers to about ten micrometers. By this means, they can adjust the electrical and optical properties to optimize performance for different applications.

Epic Research Endeavor Reveals Cause of Deadly Digestive Disease in Children
Lawrence Berkeley National Laboratory

Nearly ten years ago, a group of Israeli clinical researchers emailed Berkeley Lab geneticist Len Pennacchio to ask for his team’s help in solving the mystery of a rare inherited disease that caused extreme, and sometimes fatal, chronic diarrhea in children.

Discovered: A new way to measure the stability of next-generation magnetic fusion devices
Princeton Plasma Physics Laboratory

Feature reports discovery of an alternative method for measuring the stability of fusion plasma, a critical task for researchers seeking to bring the fusion that powers the sun to Earth.

Can’t Take the Heat? ‘Cool Walls’ Can Reduce Energy Costs, Pollution
Lawrence Berkeley National Laboratory

A Berkeley Lab study modeled different types and ages of homes, retail stores, and office buildings and found that sunlight-reflecting “cool” exterior walls can save as much or more energy than sunlight-reflecting cool roofs in many places across the U.S.

Augustana University Professor’s Research Leads to Surprising Mating Decision in Butterfly Species
Augustana University, South Dakota

The males of one species of butterfly are more attracted to females that are active, not necessarily what they look like, according to a recent research conducted at Augustana University.The paper, “Behaviour before beauty: Signal weighting during mate selection in the butterfly Papilio polytes,” found that males of the species noticed the activity levels of potential female mates, not their markings.
