Ancient brown bear genomes shed light on Ice Age losses and survival
The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyen.....»»
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'.....»»
Once-endangered Kirtland"s warblers show extensive signs of inbreeding in genome
The genome of a once-endangered songbird shows extensive signs of inbreeding, according to a new study by Penn State researchers. Because inbreeding can negatively impact survival and reproduction, the results could guide continuing conservation effo.....»»
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.....»»
Geneticists have finally solved the mystery of Garfield"s orange coat
Garfield, star of the eponymous comic strip created by Jim Davis in 1978, is, like many of the cats that roam our homes, orange. He is orange in the same way that some people are redheaded, some horses are brown, or some dogs are Irish setters, but t.....»»
PowerWash Simulator’s latest seasonal update is here, and it’s festive
If you've left Muckville clean enough to satisfy even its picky residents, this new task of cleaning up the Ice Rink is perfect for you......»»
With their new movie Y2K, Kyle Mooney and Evan Winter invite you to 1999’s deadliest party
In an interview with Digital Trends, Kyle Mooney and Evan Winter discuss their new film Y2K and how they used nostalgia to power this coming-of-age story......»»
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.....»»
Lizards and snakes are 35 million years older than we thought
Reanalysis of a fossil finds that reptiles' traits go back earlier than we thought. Lizards are ancient creatures. They were around before the dinosaurs and persisted long after d.....»»
World"s oldest known wild bird is expecting again, aged 74
Parenting can be tough, even for the young and energetic, but one elderly albatross is about to go through it all again—at the ripe old (and apparently record-setting) age of 74......»»
Record-low Antarctic sea ice can be explained and forecast months out by patterns in winds
Amid all the changes in Earth's climate, sea ice in the stormy Southern Ocean surrounding Antarctica was, for a long time, an odd exception. The maximum winter sea ice cover remained steady or even increased slightly from the late 1970s through 2015,.....»»
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.....»»
Beaver survey aims to show the urban benefits of Chicago"s "ecosystem engineers"
As the boat zipped down the Chicago River on a nippy November morning, Sammie Clark stood up and pointed at a creature swimming in the water, its brown fur slick and its head bobbing just above the surface. It kept close to the edge, a sheet metal wa.....»»
Triassic reptile with unusual jaws named as a new species
A new species of ancient reptile has been named after spending more than 200 million years buried in the ground. Threordatoth chasmatos was one of the last survivors of the procolophonids, a group of lizard-like animals that were once widespread duri.....»»
The moon"s biggest and most ancient crater is more circular than previously thought
The South Pole-Aitken basin is the moon's oldest and largest visible crater—a massive geological wound 4 billion years old that preserves secrets about the moon's early history, much like a lunar time capsule......»»
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.....»»
