Phys.org / Hair-width LEDs could eventually replace lasers
LEDs no wider than a human hair could soon take on work traditionally handled by lasers, from moving data inside server racks to powering next-generation displays. New research co-authored by UC Santa Barbara doctoral student ...
Phys.org / Jupiter's Galilean moons may have gained life's building blocks at birth
Southwest Research Institute was part of an international team that demonstrated how complex organic molecules (COMs), key chemical precursors to life, could have been incorporated into Jupiter's Galilean moons during their ...
Phys.org / Tuning in to fluorescence to farm smarter: Monitoring plant light use saves indoor farm energy costs
Plant owners with a so-called green thumb often seem to have a more finely tuned sense of what their plants need than the rest of us. A new "smart lighting" system for indoor vertical farms grants this ability on a facility-wide ...
Phys.org / Astronomers discover rare super-Jupiter orbiting distant star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new exoplanet orbiting a distant star known as TIC-65910228. The newfound alien world is slightly larger and ...
Phys.org / Alloy-engineered valleytronics: Microscopic mechanism gives scientists precise control over how excitons behave
Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up tangible prospects for technological ...
Phys.org / How cells manage nitric oxide: Research uncovers dynamic 'gate' that tames powerful signaling molecule
Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate blood pressure, brain ...
Phys.org / Between flood and drought: The metric that could better explain what happens to water in the age of climate change
A key question in any discussion about climate is "How much rain fell?" But perhaps there is an even more important one. Like any household budget, the global water economy is based on "income," that is, water entering the ...
Phys.org / Ant queen frozen in time: New ant species found in Dominican amber
A study by Dr. Gianpiero Fiorentino and his colleagues, published in the Journal of Paleontology, describes the identification of a new species of ant, Hypoponera electrocacica, belonging to the genus Hypoponera and representing ...
Phys.org / From algae to biofuel: Study opens doors to cheaper, cleaner fuel sources
A researcher's keen eye and spirit of curiosity led to the discovery of a new method for cell engineering—a finding that opens doors to more sustainable sources for everything from fuel to vitamin supplements.
Phys.org / Between the Pampa and Patagonia: New clues about how ancient hunter-gatherers fed themselves
An archaeological study reveals how ancient hunter-gatherer groups lived—and survived—more than a thousand years ago in the transition zone between the Pampas and Patagonia in Argentina. The research, carried out by Martínez ...
Phys.org / A new method reveals hidden rules of gene control
Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, revealing transcription ...
Phys.org / Courtship is complicated, even in fruit flies
Love is in the air for the vinegar fly. Drosophila melanogaster has long been a model for understanding how brains translate sensory information into courtship behavior. Male flies perform a multitude of romantic actions—orienting, ...
