Hunting for Neutrinos: When the Ordinary Is Unexpected

Department of Energy, Office of Science

Neutrinos are the most abundant particles in the universe and could reveal insight into physics beyond the Standard Model. However, they’re incredibly difficult to detect. While most neutrino detectors are very large, two experiments supported by the Department of Energy at Oak Ridge National Laboratory are poised to demonstrate that even modest neutrino experiments can make big discoveries.

Climate Warming Causes Local Extinction of Rocky Mountain Wildflower Species

University of Colorado Boulder

New University of Colorado Boulder-led research has established a causal link between climate warming and the localized extinction of a common Rocky Mountain flowering plant, a result that could serve as a herald of future population declines.

Ancient-DNA Researchers Surpass the 1,000-Genome Milestone, Sharpening Resolution of European Prehistory

Harvard Medical School

In the last eight years, the field of ancient DNA research has expanded from just one ancient human genome to more than 1,300. The latest 625 of those genomes debut Feb. 21 in two papers published simultaneously in Nature, including the largest study of ancient DNA to date.

In a First, Tiny Diamond Anvils Trigger Chemical Reactions by Squeezing

SLAC National Accelerator Laboratory

Menlo Park, Calif. —Scientists have turned the smallest possible bits of diamond and other super-hard specks into “molecular anvils” that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.

Cross-Bred Flies Reveal New Clues About How Proteins Are Regulated

Scripps Research Institute

A team from The Scripps Research Institute (TSRI) has revealed that by crossing two species of flies, they can use what they learn from the proteome of the hybrid offspring to find new clues about how proteins interact with each other

Berkeley Lab “Minimalist Machine Learning” Algorithms Analyze Images From Very Little Data

Lawrence Berkeley National Laboratory

Berkeley Lab mathematicians have developed a new approach to machine learning aimed at experimental imaging data. Rather than relying on the tens or hundreds of thousands of images used by typical machine learning methods, this new approach “learns” much more quickly and requires far fewer images.
