Researchers found that TIMP2 supports microglial function and reduces age-related cellular changes associated with inflammation in mice. As the brain grows older, its immune cells can become less effective at clearing debris and controlling potentially harmful responses. Researchers at The Icahn School of Medicine at Mount Sinai have identified a role for TIMP2, a protein [...]

Continuous tracking of one participant showed how metabolic and physiological health measures can shift substantially over time in response to lifestyle changes. Most people learn about their health through an annual screening, a single snapshot that can miss what happens during the rest of the year. Researchers at the Yong Loo Lin School of Medicine, [...]

A study challenges the idea that Barbarians simply dominated Europe during the Early Middle Ages. A new study from the HistoGenes project, whose co-PI includes Patrick Geary, Professor Emeritus in the School of Historical Studies, is helping scholars build a clearer picture of the early medieval people who lived in Western Europe after the fall [...]

Roman female farm managers likely oversaw valuable agricultural production rather than serving only as housekeepers. Across five centuries of Roman laws, literature, and grave inscriptions, female farm managers repeatedly appear in the surviving record. Yet modern historians have often treated them as housekeepers responsible for meals and domestic work, separate from the farm’s productive operat…

Dasosaurus tocantinensis was about 20 meters long and lived roughly 120 million years ago. Its closest known relative inhabited what is now Spain. About 120 million years ago, a 20-meter-long dinosaur roamed what is now northeastern Brazil, leaving behind fossils that would remain buried until modern construction exposed them. A new study in the Journal [...]

A simpler method for measuring DNA-bound phosphorus could improve understanding of soil microbes and nutrient cycling. Scientists have created a simpler, more cost-effective way to measure a biologically important form of phosphorus in soil. The method offers a clearer view of how nutrients move through soils and could help guide more sustainable farming practices. Phosphorus [...]

Researchers say two more major calving events are likely. A massive slab of floating ice broke away from Petermann Glacier in northwest Greenland on August 4, 2026, creating a 76.4 km² ice island. An international research group led in part by the University of Ottawa says it was Petermann’s largest floating ice loss since 2012 [...]

Nearly three decades of airborne radar observations have identified four features that help storms become organized before they intensify. A tropical cyclone can look powerful from above yet still struggle to strengthen if its circulation is leaning through the atmosphere. Before substantial intensification can occur, the rotating centers at different heights generally need to line [...]

Swinburne researchers have discovered how broccoli could help treat an extremely rare and incurable disease that affects only about 200 Australians. A naturally occurring compound in broccoli is being investigated as a possible treatment for Friedreich ataxia, a rare nervous system disease. Research from Swinburne suggests the compound can act on biological processes involved in [...]

A study suggests that combining the two compounds with conventional treatment could reduce the need for antibiotics. For people with severe periodontitis, controlling the disease can require more than the standard removal of bacterial buildup beneath the gums. A study involving 109 patients found that adding omega-3 and low-dose acetylsalicylic acid (ASA) to conventional treatment [...]

U.S. poison centers have recorded a sharp long-term rise in liver injuries linked to medications and other foreign substances, with most severe enough to require inpatient care. Reports to U.S. poison centers involving liver damage from medications, supplements, alcohol, and other substances rose nearly 400% between 2000 and 2024, according to research from UVA Health. [...]

Rocky planets may have gotten their start far earlier than anyone expected, almost as soon as the first stars gave the universe the ingredients to build them. New computer simulations suggest that planetesimals, the solid precursors of planets like Earth, could have formed only about 100 million years after the Big Bang. At that point, [...]

Direct imaging has revealed strong evidence that Betelgeuse is orbited by a companion two to three times as massive as the Sun. For generations, Betelgeuse has appeared to the naked eye as a single reddish point in the constellation Orion. Now astronomers have obtained their strongest evidence yet that the famous star has company. Using [...]

Something in the young universe is shining like a star that should not be possible. NASA’s James Webb Space Telescope has detected a compact red object so luminous that ordinary nuclear fusion cannot plausibly explain it. Although the source has a star-like appearance and may be surrounded by gas on the scale of the solar [...]

MIT and University of Ferrara researchers created a mathematical blueprint for designing distinguishable non-Gaussian quantum states. Researchers worldwide are working to develop quantum systems for sensing, communications, computing, and control that could outperform today’s technologies. A major challenge is creating quantum states that are stable, measurable, and easy to distinguish, since the…

A layer once dismissed as mere support has transformed a tiny photonic chip into a powerful generator of new light frequencies. A laser usually produces one narrow color of light. A device small enough to sit on a fingertip can turn that single input into hundreds of precisely spaced frequencies, creating a tool for measuring [...]

The microscopic magnetic flips behind digital memory could soon use thousands of times less energy, offering a new way to shrink AI’s rapidly growing power footprint. Artificial intelligence is creating and processing data on an enormous scale. Searches, recommendations, generated images, scientific simulations, and large language models all depend on information that must be repeatedly [...]

Researchers have identified shared biological changes across different genetic forms of autism, despite the disorder’s extensive genetic diversity. Hundreds of genes have been associated with autism, but scientists still do not fully understand the molecular and cellular processes that drive the condition. A new study published in Nature, led by Gaia Novarino at the Institute [...]

Ancient microbes appear to have used molybdenum as far back as 3.7 billion years ago, despite the metal being scarce in Earth’s early oceans. Scientists funded by NASA have found that organisms living on Earth more than 3 billion years ago were already using molybdenum, even though the metal was extremely rare in the environment [...]

A decades-old experiment in Victoria’s mountain ash forests is challenging assumptions about the trade-offs between timber production and conservation. Should a forest remain untouched, or should some trees be harvested to sustain nearby communities and economies? Australians have debated these competing approaches for decades, often treating conservation and timber production as mutually exclusi…
