Why do humans possess a twisted birth canal?
The relatively narrow human birth canal presumably evolved as a "compromise" between its abilities for parturition, support of the inner organs, and upright walking. But not only the size of the birth canal, also its complex, "twisted" shape is an ev.....»»
Adding an alternating magnetic field to layers of twisted graphene creates even more exotic properties
Magnetic fields can engineer flat bands in twisted graphene layers to create a new playground for exotic physics, RIKEN physicists have shown......»»
Australian government trial finds AI is much worse than humans at summarizing
Llama2-70B failed to capture "complex context," but updated models might do better. Enlarge / ASIC evaluators found AI summaries were often "wordy and pointless—just repeating what was in the submission." (credit: Getty Images).....»»
Dozens of viruses detected in Chinese fur farm animals
Dozens of viruses have been detected mixing in animals at fur farms in China, some of which are new and have the potential to spill over into humans, researchers said Wednesday......»»
The world"s fastest single-shot 2D imaging technique films ultrafast dynamics in flames
Candle flames and airplane engines produce tiny soot particles from polycyclic aromatic hydrocarbons (PAHs) as their precursors, both of which are harmful to humans and the environment. These carbon-based particles are also common in space, making up.....»»
Denmark reports cases of bluetongue disease that can be fatal to sheep but is harmless to humans
Denmark reported Tuesday cases of bluetongue in the country's east, a non-contagious, insect-borne viral disease that is harmless to humans but can be fatal for so-called ruminant animals—mainly sheep but also cows and goats......»»
Is there such a thing as an objectively beautiful building? Here"s the science
Some people assume that there's a type of beauty that everyone can agree on. But did early humans really admire slender bodies the way we do today? After all, fashions come and go—there have been plenty of fads throughout history that we find hard.....»»
NASA lines up return date for Boeing Starliner minus humans
A Butch- and Suni-less Boeing Starliner has been given a date to return to Earth by NASA......»»
Revealed — How much Target is selling the Keurig K-Cafe Special for on Labor Day
Keurig Around these parts we love the , surprises, and sneaky reveals just as much as the next batch of humans. What we don’t like? Unnecessary extra effort. But we’re willing to go through extra steps to help you out. In Target’s L.....»»
Ancient viral genomes preserved in glaciers reveal climate history—and how viruses adapt to climate change
As humans alter the planet's climate and ecosystems, scientists are looking to Earth's history to help predict what may unfold from climate change. To this end, massive ice structures like glaciers serve as nature's freezers, archiving detailed recor.....»»
The Mediterranean dried out 5.5 million years ago, offering sobering lessons for humanity today
What would happen if humans dried out the Mediterranean sea, turning it into a giant salt lake? Would its wildlife survive, and if so, how long would it take to recover?.....»»
Spin-controlled generation of a complete polarization set with randomly interleaved plasmonic metasurfaces
Optical metasurfaces are finely crafted two-dimensional artificial nanostructures composed of meticulously designed arrays of ultrathin artificial atoms. These surfaces possess capabilities beyond natural materials, enabling multifunctional control o.....»»
What a submerged ancient bridge discovered in a Spanish cave reveals about early human settlement
A new study led by the University of South Florida has shed light on the human colonization of the western Mediterranean, revealing that humans settled there much earlier than previously believed. This research, detailed in a recent issue of the jour.....»»
Uncovering the secret communication of marmoset monkeys: They have names
A new study from Hebrew University reveals that marmoset monkeys use specific calls, known as "phee-calls," to name each other, a behavior previously known to exist only in humans, dolphins, and elephants. This discovery highlights the complexity of.....»»
Researchers create entangled quantum magnets with protected quantum excitations
When different quantum states combine, new collective states of matter can emerge. In the quantum realm, combining components such as atoms that possess quantum effects can give rise to macroscopic quantum states of matter, featuring exotic quantum e.....»»
Study finds people are consistently and confidently wrong about those with opposing views
Despite being highly confident that they can understand the minds of people with opposing viewpoints, the assumptions humans make about others are often wrong, according to new research from the Institute of Psychiatry, Psychology & Neuroscience (IoP.....»»
Researchers model physics of the pumping technique used to achieve air on a skateboard half-pipe
A team of engineers and mathematicians from ETH Zürich, working with colleagues from The Institute of Statistical Mathematics, and ATR Institute International, both in Japan, has successfully modeled the physics involved when humans pump on skateboa.....»»
Dark matter could have helped make supermassive black holes in the early universe
It takes a long time for supermassive black holes, like the one at the center of our Milky Way galaxy, to form. Typically, the birth of a black hole requires a giant star with the mass of at least 50 of our suns to burn out—a process that can take.....»»
In six new rogue worlds, Webb Telescope finds more star birth clues
The James Webb Space Telescope has spotted six likely rogue worlds—objects with planetlike masses but untethered from any star's gravity—including the lightest ever identified with a dusty disk around it......»»
Widespread culling of crocodiles is not an effective way to stop attacks on humans, study shows
Education and community awareness, removal of problem animals and exclusion areas are significantly more effective in reducing saltwater crocodile attacks in the Northern Territory than a widespread culling program to reduce crocodile numbers, accord.....»»
Superconductivity study confirms existence of edge supercurrents
Topological materials are materials that have unusual properties that arise because their wavefunction—the physical law guiding the electrons—is knotted or twisted. Where the topological material meets the surrounding space, the wavefunction must.....»»
