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.....»»
New congressional report: “COVID-19 most likely emerged from a laboratory”
A textbook example of shifting the standards of evidence to suit its authors' needs. Recently, Congress' Select Subcommittee on the Coronavirus Pandemic released its final report......»»
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.....»»
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.....»»
New technique for spotting Dyson rings unveiled
Dyson spheres and rings have always held a special fascination for me. The concept is simple: build a great big structure either as a sphere or ring to harness the energy from a star. Dyson rings are far more simple and feasible to construct and in a.....»»
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......»»
Rethinking the quantum chip: Engineers present new design for superconducting quantum processor
Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution dem.....»»
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.....»»
Study finds increased income boosts birthweight outcomes
Higher incomes are often correlated with healthier pregnancies and babies, but is it really the money that matters? Sedimentary rocks that formed 390 million years ago, surprisingly, help provide the answer, at least for those who live above the Marc.....»»
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.....»»
In vivo electrochemistry could provide early detection of high-altitude hypoxic brain injury
People who climb too fast or too high risk acute altitude sickness, which can lead to life-threatening hypoxic brain injury. By using in vivo electrochemistry, researchers have demonstrated that characteristic changes occur in the oxygen content of v.....»»
Getting to the bottom of things: Latrine findings help researchers trace movement of people and disease
A McMaster researcher has uncovered evidence of intestinal parasites in a 500-year-old latrine from Bruges, Belgium, and while the finding may induce queasiness in some, it is expected to provide important scientific evidence on how infectious diseas.....»»
