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 / 40,000-year-old Stone Age symbols may have paved the way for writing, long before Mesopotamia
Over 40,000 years ago, our early ancestors were already carving signs into tools and sculptures. According to a new analysis by linguist Christian Bentz at Saarland University and archaeologist Ewa Dutkiewicz at the Museum ...
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 / Finding the honey bee dance floor: New method shows how it moves within the hive
When honey bees find a good source of food, they return to their hive and perform a waggle dance. It consists of a series of movements that communicate the direction and distance to nectar, pollen or water relative to the ...
Phys.org / A new form of aluminum unlocks sustainable and cheaper catalysts
A research team at King's College London has isolated a new form of aluminum—a highly abundant metal, that could provide a far cheaper and more sustainable alternative to commonly used rare earth metals. Dr. Clare Bakewell, ...
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 / CT scans of Inca child sacrifices reveal new details about capacocha rituals
The Incas were known to engage in a sacrificial ritual involving children to appease their gods. Archaeologists have found and analyzed the remains of these human sacrifices, although not all of them have undergone CT scanning, ...
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 / Auroras on Ganymede and Earth share striking similarities
New observations of Ganymede reveal a striking similarity between the auroras on the largest moon in the solar system and those on Earth. The international team of astrophysicists, led by researchers from the University of ...
Phys.org / Early-life challenges and experiences shape how boldly bats behave as adults
What makes one bat take risks and venture far from its roost in search of food, while another stays close to familiar, safer areas? A new study from Tel Aviv University's School of Zoology reveals that the environment in ...
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 ...
