For decades, light has been used to understand the molecular structures of matter. A sample is irradiated with light, and measurements determine the wavelengths at which it is absorbed. Since each molecule absorbs light at very specific wavelengths that depend on its structure, the resulting absorption spectrum acts like a molecular fingerprint. For individual molecules, however, this signal is vanishingly small and mostly indistinguishable from noise. https://phys.org/news/2026-08-molecule-photon-entanglement-imperceptible-recoil.html Optics & Photonics Wed, 26 Aug 2026 11:00:14 EDT news706866181 Researchers at UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS) are blazing a trail through the Wild West of AI-assisted science, with a field guide aimed at environmental data scientists. https://phys.org/news/2026-08-field-wild-west-ai-environmental.html Environment Wed, 26 Aug 2026 10:00:05 EDT news706955941 In a dry shrubland, a gecko sprints toward shelter. Its greatest danger is not a predator, although hawks circle overhead and sand cats wait in ambush. Rather, its most pressing concern is dehydration. Its skin is paper-thin; water can evaporate from its body into the dry air more quickly than it can replenish it. Fortunately, evolution has given it an adaptation: thin, nanoscopic hairs, called setulae, that cover its body and trap moisture. https://phys.org/news/2026-08-nanoscale-hairs-gecko-skin-moisture.html Plants & Animals Tue, 25 Aug 2026 11:00:03 EDT news706779841 In the last few centuries, mammals and other animals have been going extinct at least 100 times faster than they did before humans arrived on the scene. So who will be next? Which species are most likely to survive, and which will die out? https://phys.org/news/2026-08-extinctions-extinction-today.html Plants & Animals Thu, 20 Aug 2026 15:30:02 EDT news706456261 Many animals obtain information about others from scent marks left in the environment, including urine. Because these marks remain after the sender has left, they allow animals to communicate across space and time. But odor molecules evaporate, degrade and change after release. How, then, can a scent mark continue to convey reliable information about who left it? https://phys.org/news/2026-08-year-mystery-cat-kidney-linked.html Molecular & Computational biology Wed, 19 Aug 2026 11:00:26 EDT news706194782 An African bat whose presence in Sicily had remained an unresolved zoological mystery for almost two centuries has now been documented on Pantelleria Island. A study published in Global Ecology and Conservation reports the first solid evidence of the Egyptian slit-faced bat (Nycteris thebaica) in Europe, adding not only a new bat species but also the first representative of the family Nycteridae to the European fauna. https://phys.org/news/2026-08-african-overlooked-centuries-europe.html Plants & Animals Tue, 18 Aug 2026 15:10:01 EDT news706282441 A distinctive black or dark brown lesion that appears on the eyes of some cats has long puzzled veterinarians. Now, researchers have identified two elements that may help explain what is happening inside the affected cornea. https://phys.org/news/2026-08-elements-clues-mysterious-black-eye.html Veterinary medicine Mon, 17 Aug 2026 12:20:08 EDT news706181222 Scientists from the Pontificia Universidad Católica del Ecuador officially described Pristimantis milpe, an abundant and widely distributed species that had been confused with another species for more than a century. To solve the mystery, researchers reviewed historical specimens collected in Ecuador during the 19th century and preserved at the Natural History Museum in London. https://phys.org/news/2026-08-mystery-london-discovery-ecuadorian-frog.html Plants & Animals Thu, 13 Aug 2026 17:20:04 EDT news705846001 An international team of researchers from Belgium, France, Switzerland, Spain and the U.S. has reconstructed the evolution of body mass in carnivorous mammals during the Paleogene—a crucial window in the diversification of mammals that followed the extinction of dinosaurs. This work, published in Biology Letters, challenges the long-standing hypothesis that competition decided the fate of ancient top predators. https://phys.org/news/2026-08-climate-predator-million-years.html Ecology Thu, 13 Aug 2026 13:40:03 EDT news705841742 Charting a better future will require redressing the problems of the past. That's one reason many countries have begun to return dispossessed land to Indigenous peoples. The goal of Indigenous land restitution is to empower disadvantaged communities and entrust land management back to the region's traditional stewards. In many cases, these programs also carry expectations of broad environmental benefits. However, there's been relatively little research testing this assumption. https://phys.org/news/2026-08-indigenous-restitution-empowers-communities-environmental.html Environment Thu, 13 Aug 2026 12:00:07 EDT news705840061 According to new research, viewers often dismiss, trivialize or even romanticize signs of cat distress during "play" interactions, raising concerns for cat welfare. https://phys.org/news/2026-08-internet-cats.html Plants & Animals Wed, 12 Aug 2026 10:20:06 EDT news705745323 For most healthy people, Cryptococcus is an unnoticed infection. The immune system walls it off in the lungs and keeps it dormant for life. But in patients undergoing cancer chemotherapy, recovering from an organ transplant, living with HIV or taking newer immunosuppressing drugs for autoimmune disease, the fungus can reactivate, spread to the brain and cause meningitis. https://phys.org/news/2026-08-uncovering-cryptococcus-shifts-silent-infection.html Cell & Microbiology Mon, 10 Aug 2026 17:30:01 EDT news705600902 Using light to process quantum information is one of the most promising approaches to building future quantum computers. Light particles, known as photons, are excellent carriers of quantum information, but their lack of natural interactions has created a major challenge for researchers seeking to build systems capable of performing a full range of computations. https://phys.org/news/2026-08-shifting-architecture-versatility-photonic-quantum.html Optics & Photonics Fri, 07 Aug 2026 17:00:01 EDT news705325201 A new study by ancient DNA researchers at the University of California, Santa Cruz, used paleogenomics to create a genetic roadmap to help guide the restoration of another iconic species once on the brink of extinction: the North American bison. https://phys.org/news/2026-08-decoding-north-american-bison-genome.html Plants & Animals Thu, 06 Aug 2026 18:10:01 EDT news705256562 Living among large predatory carnivores could actually make you safer. A study published in the journal Current Biology found that pumas—wild cats also known as mountain lions, cougars or panthers—change deer behavior, leading to fewer collisions with cars on roadways. In areas where puma occupancy is high, the authors report a significant reduction in the total expected number of collisions over a 5-year period. https://phys.org/news/2026-08-pumas-roads-safer-drivers-prey.html Plants & Animals Wed, 05 Aug 2026 11:00:11 EDT news705059578 For the first time, researchers have discovered a new species of extinct amphibian from Ice Age Los Angeles at La Brea Tar Pits: a spadefoot toad they have named Spea labreae. Only one other extinct Pleistocene amphibian from North America has ever been found (a tree frog from Florida). https://phys.org/news/2026-08-species-ice-age-toad-la.html Ecology Wed, 05 Aug 2026 03:00:01 EDT news705052441 Ants live in highly organized colonies and cooperate daily to tackle a wide range of problems. Their striking group behaviors have fascinated biologists for centuries and even inspired the development of various artificial intelligence (AI) systems. https://phys.org/news/2026-08-ant-teams-gravity-based-puzzle.html Plants & Animals Mon, 03 Aug 2026 15:20:10 EDT news704987373 In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which sock goes on first). Noncommutative means the order does matter. https://phys.org/news/2026-07-explored-quantum-code-powerful-stable.html Quantum Physics Fri, 31 Jul 2026 10:00:04 EDT news704709901 Until the Panamanian isthmus formed about 2.8 million years ago, North and South America were isolated continents with unique groups of animals. A riot of marsupials—mammals with brood pouches—and sloths in the south contrasted with camels, horses, pronghorn antelopes and saber-toothed cats in the north. https://phys.org/news/2026-07-north-south-america-mammals-intermingle.html Paleontology & Fossils Thu, 30 Jul 2026 14:00:01 EDT news704548501 Many of today's electronic devices—from the semiconductors in your cell phone to the photovoltaic cells in your solar panels—are built on thin-film substrates. The thin film is an electrically conductive material, while the substrate is an inert material. Or is it? https://phys.org/news/2026-07-thin-substrates-longer-inert-path.html Nanophysics Mon, 27 Jul 2026 18:00:05 EDT news704382661 The fossilized spines of saber-toothed cats in the La Brea Tar Pits reveal evidence of an unexpectedly high prevalence of rare spinal nerve tumors, suggesting that the species became inbred just before extinction. These tumors, which cause significant pain and reduced limb function, could have made the cats particularly vulnerable to the lure of prey animals stuck in the tar pits. https://phys.org/news/2026-07-saber-toothed-cats-spinal-tumors.html Evolution Mon, 27 Jul 2026 00:00:01 EDT news704106361 Evolution is all about trade-offs. Traits that may be beneficial in one situation may backfire in another. Over millions of years, species can become specialized for one way of living rather than being equally good at everything. This explains why mammal teeth look the way they do today. https://phys.org/news/2026-07-evolution-mammal-teeth-slice-equally.html Evolution Fri, 24 Jul 2026 11:20:01 EDT news704105217 A new study from Edith Cowan University (ECU) confirms that the presence of fungal food resources is important for supporting the reintroduction of two threatened marsupials to the Shark Bay World Heritage area, which could simultaneously advance species conservation and ecosystem restoration. This study, led by Edith Cowan University Ph.D. candidate Rebecca Quah, took place at six sites across Western Australia and the Northern Territory, including Dirk Hartog Island in Shark Bay. https://phys.org/news/2026-07-truffles-menu-threatened-marsupials-world.html Plants & Animals Tue, 21 Jul 2026 17:00:09 EDT news703862221 New research has uncovered the complex biological history preserved within DNA traces found on the Shroud of Turin, offering fresh insights into one of the world's most studied and debated historical artifacts. https://phys.org/news/2026-07-shroud-turin-dna-biological-history.html Cell & Microbiology Mon, 20 Jul 2026 13:00:06 EDT news703770901 A parasite carried by billions of people worldwide often causes harmful infections during pregnancy and in immunocompromised individuals and is a leading infectious cause of blindness in South America.
