Johns Hopkins researchers searching the expanse of the universe for the existence of the first black holes are zeroing in on little red dots that may hold the key to the theoretical phenomenon.
Phys.org ResearchRead article →A new research paper describes a statistical framework that resolves significant calculation biases caused by artificial intelligence in econometric models. The method, two-step extraction, removes estimation bias when researchers measure the business or economic effects of variables extracted using machine learning algorithms from unstructured data such as photos and consumer text.
Phys.org ResearchRead article →It is one of the great questions of mathematics: What does "infinity" actually mean? Which infinities are larger than others? Can infinities be arranged in a sequence, like the rungs of an endless ladder, so that for any two of them we can always say which one lies above the other?
Phys.org ResearchRead article →Most young children like sharks, with almost seven in 10 describing them in a positive light, but a new study has found that associations between sharks and fear become more common as children get older.
Phys.org ResearchRead article →Researchers have proposed a breakthrough technique for reading quantum information without destroying the delicate states that make quantum computers work. By detecting an electrical signal generated by the qubit itself, their method achieved up to 99.85% accuracy in simulations and could make future quantum computers simpler and more efficient.
ScienceDaily AllRead article →Scientists have discovered how to reprogram the internal structure of glass using a special molecule that rearranges chemical bonds while lowering the melting temperature. The breakthrough could unlock entirely new glass materials with precisely controlled magnetic and optical properties, opening possibilities for advanced electronics, sensors, and other technologies.
ScienceDaily AllRead article →Scientists have developed a revolutionary gel that could regrow lost tooth enamel by harnessing minerals naturally found in saliva, potentially overcoming one of dentistry’s biggest limitations. The regenerated enamel behaves much like healthy enamel, raising hopes for a simple treatment that could repair damaged teeth, prevent decay, and reduce sensitivity.
ScienceDaily AllRead article →Scientists have solved a decades-old mystery and uncovered a hidden immune system defense that protects healthy cells from the very inflammation meant to fight infections. The surprising discovery could lead to new approaches for treating cancer, inflammatory bowel disease, and other conditions involving excessive inflammation.
ScienceDailyRead article →Scientists have uncovered a surprising link between Alzheimer’s-related protein buildup, disrupted brain waves during deep sleep, and fading memory. The findings suggest that hidden changes in how the brain processes memories overnight may contribute to age-related memory loss long before Alzheimer’s symptoms appear.
ScienceDailyRead article →Scientists are advancing a promising new way to fight antibiotic-resistant infections by using viruses that specifically target and kill harmful bacteria. An international team has released the first coordinated guidelines for personalized phage therapy, offering a roadmap for safely bringing this experimental treatment into clinical practice.
ScienceDailyRead article →A groundbreaking discovery is rewriting the story of human evolution, revealing that an ancient human species once thought to be an evolutionary dead end may have left genetic traces in people alive today. By extracting proteins from 400,000-year-old Homo erectus teeth discovered in China, scientists uncovered evidence suggesting that these early humans interbred with Denisovans, another mysterious ancient human…
ScienceDailyRead article →Scientists have developed a remarkable new membrane that separates crude oil at room temperature, using the oil itself to create microscopic filtration channels. The breakthrough could cut refining energy consumption by nearly 32%, carbon emissions by almost 38%, and operating costs by 36%, potentially transforming one of the world's most energy-intensive industries.
ScienceDailyRead article →Adding phenanthrene as a co-guest let the second-generation crystalline sponge (2G-CS) method determine X-ray structures for 24 of 30 small, low-polarity C₁₅ molecules, mostly sesquiterpenoids. Under standard conditions, none of the 30 gave guest-containing crystals. Eleven of the 24 structures had not been reported before, including that of the liquid hydrocarbon longifolene.
Phys.org ResearchRead article →When plants encounter pathogens, they can defend themselves by rapidly killing infected cells to restrict pathogen spread. This immune response, known as the hypersensitive response (HR), was first described in 1915. However, the molecular mechanism underlying HR cell death remained poorly understood for more than a century.
Phys.org ResearchRead article →A new experiment reveals that Earth's microbes can grow in harsh conditions similar to what may exist just below the surface of Mars, suggesting new directions in the search for potential cellular life on the red planet.
Phys.org ResearchRead article →Nudges—the subtle interventions that encourage people to make beneficial decisions without forcing them into these choices—are a popular marketing tool widely used for a variety of social causes and business purposes. But their effectiveness depends on finding the right combination of context and content, says Siddharth Bhattacharya, an assistant professor of information systems and operations management at the…
Phys.org ResearchRead article →There are no woodpeckers on the Hawaiian Islands, but a little yellow bird called the 'akiapōlāʻau (Ah-key-ah-pole-ah-ow) has evolved an unusual beak to drill into branches to find food.
Phys.org ResearchRead article →This Hubble image features the sparkling collection of stars named Messier 30 (M30), also called NGC 7099.
NASARead article →The sun hangs low over the plains of Castile and León, in the north-central region of Spain. But from a slope of the mountain Pico Trigaza, it appears that a few puffy white clouds have started to block the sun. That’s vexing. A group of researchers, some wearing cardboard eclipse glasses, is clustered around sets of portable telescopes and cameras connected to laptops.
IEEE SpectrumRead article →Researchers have long known that releasing domesticated ducks can alter wild populations. Now, a study led by a doctoral student at The University of Texas at El Paso has documented, for the first time in North America, when and where these genetic changes took place and tied them directly to more than a century of releases.
Phys.org ResearchRead article →In order to know where you're going, you must know where you've been, says an old adage. And a new UNLV housing supply rankings report is putting that proverb into practice by providing policymakers and the public with the nation's first comprehensive look at how state-level new home permitting activity stacks up—and offering clues on local, state or regional measures that could help drive down skyrocketing prices.
Phys.org ResearchRead article →Three new peer-reviewed publications help to fill critical gaps in knowledge about Central America's freshwater ecosystems, which support extraordinary biodiversity but remain among the least-studied ecosystems in the world.
Phys.org ResearchRead article →Scientists at Lancaster University have observed the hidden tongue movements accompanying a centuries-old change in English speech—offering a rare glimpse of language transforming in real time. Linguists have used ultrasound imaging to observe one of these changes as it unfolds inside the mouths of speakers from Blackburn, Lancashire—one of the few places in England where many older speakers still pronounce the…
Phys.org ResearchRead article →Researchers at the University of Sydney have identified a fundamental mathematical reason why artificial intelligence systems can learn different behaviors even when trained under almost identical conditions, a discovery that could help improve the reliability and trustworthiness of AI technologies.
