Shining a light on Colorado"s little-known fireflies
Owen Martin steps carefully through the knee-high grass growing up around a long-abandoned railroad track near Sawhill Ponds in Boulder, Colorado. It's almost pitch black out. The sun set 45 minutes ago, and the only light now comes from the distant.....»»
Stone Age insights: Life, death and fire in ancient Ukraine
A research group led by Johannes Müller at the Institute of Prehistoric and Protohistoric Archaeology, at Kiel University, Germany, have shed light on the lives of people who lived over 5,600 years ago near Kosenivka, Ukraine......»»
Noninvasive imaging method can penetrate deeper into living tissue
Metabolic imaging is a noninvasive method that enables clinicians and scientists to study living cells using laser light, which can help them assess disease progression and treatment responses......»»
Astronomers discover magnetic loops around supermassive black hole
NGC 1068 is a well-known, relatively nearby, bright galaxy with a supermassive black hole at its center. Despite its status as a popular target for astronomers, however, its accretion disk is obscured by thick clouds of dust and gas. A few light-year.....»»
"Zero progress": Western states at impasse in talks on Colorado River water shortages
Seven Western states that depend on the Colorado River are ending the year at an impasse in negotiations over the writing of new rules for dealing with chronic water shortages......»»
AI algorithm intensifies gold ion collisions at near-light speed
At Brookhaven National Laboratory's (BNL's) Relativistic Heavy Ion Collider (RHIC), billions of gold ions race through magnets at nearly the speed of light. Thousands of times per second, they collide head-on, breaking into smaller particles that rev.....»»
Morphology study highlights diverse jaw evolution in lizards and snakes
A University of Bristol study has shed light on how lizards and snakes—the most diverse group of land vertebrates with nearly 12,000 species—have evolved remarkably varied jaw shapes, driving their extraordinary ecological success......»»
Graphene stacking discovery could herald new era for quantum applications
Graphene, a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, is known for its exceptional properties: incredible strength (about 200 times stronger than steel), light weight, flexibility, and excellent conduction of elect.....»»
Ultrafast electron imaging captures never-before-seen nuclear motions in hydrocarbon molecules excited by light
The interactions between light and nitroaromatic hydrocarbon molecules have important implications for chemical processes in our atmosphere that can lead to smog and pollution. However, changes in molecular geometry due to interactions with light can.....»»
Apple may finally fix the worst things about the MacBook Pro
A component road map has brought to light more details about the notch's presence in the future MacBook Pro line......»»
Meet Hyperlight, Ars Technica’s new, even brighter “Light” mode
You asked, so we built it! Like many sites, apps, and operating systems, Ars Technica has both "Light" and "Dark" visual styles. They look great! But even the "Light" mode has dar.....»»
Observing gain-induced group delay between multiphoton pulses generated in a spontaneous down-conversion source
Spontaneous parametric down-conversion (SPDC) and spontaneous four-wave mixing are powerful nonlinear optical processes that can produce multi-photon beams of light with unique quantum properties. These processes could be leveraged to create various.....»»
Gurman: Apple-designed 5G modem coming to 2025 iPhones will be worse than Qualcomm’s
Apple’s long-in-the-works project to build its own cellular modem is about to see the light of day. As multiple reports have indicated in the past, select 2025 iPhone models will carry the Apple 5G modem—but thanks to a new report, now we know it.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
Discovery of key protein complex shows evolution and adaptability of photosynthetic organisms
A team of researchers has revealed the structure of a modified and evolved version of Photosystem I (PS I), a key protein complex used by plants and cyanobacteria to convert sunlight into chemical energy. This discovery sheds light on the evolution a.....»»
The Amazon rainforest as a cloud machine: How thunderstorms and plant transpiration produce condensation nuclei
The rainforest in the Amazon basin transpires vast amounts of gaseous isoprene. Until now, it was assumed that this molecule is not transported far up into the atmosphere, as it rapidly declines when exposed to light conditions. The CAFE-Brazil measu.....»»
Isotope analysis reveals mammoth as key food source for ancient Americans
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction o.....»»
Webb finds new galaxies in Spiderweb protocluster field
Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics shed light on the growth of galaxies in these large cosmic cities, with the finding t.....»»
