Neuronal adaptations shed light on anglerfish hunting behavior
Characterized by their unique adaptations to extreme environments, anglerfish are known for using lures to attract prey. Researchers at Nagoya University in Japan have discovered in frogfish (a subgroup of anglerfish) a specialized motor neuron popul.....»»
Study finds catch-and-release affects giant trevally behavior
In an effort to conserve sensitive species of fish, some sport fishing is entirely catch-and-release, meaning that the fish are returned to the water once brought ashore. However, too much fishing may affect the behavior of the target species and th.....»»

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.....»»
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.....»»
Seals" iceberg strategies: Navigating icy habitats for survival
Harbor seals in icy regions use icebergs shed by glaciers as safe platforms to give birth, care for young and molt. New research finds that as glaciers change with the climate, the resulting changes in size, speed and number of icebergs affect seals'.....»»
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.....»»
Iceland authorizes whale hunting until 2029
Iceland, one of only three countries still allowing whale hunting, on Thursday issued permits to two whaling companies for the next five years, until 2029, the outgoing government announced......»»
Navigating crises: The financial adaptations of NGOs during the COVID-19 pandemic
Demand for NGO services usually increases in times of crisis. However, a new study led by Kaunas University of Technology (KTU) in Lithuania has found that the COVID-19 pandemic had a mixed impact on NGOs working in Lithuania, Croatia, Poland and the.....»»
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
