Phys.org / After 80 years, elusive molecules reveal how ozone starts turning plant emissions into haze
Scientists have directly observed a fleeting chemical reaction that creates a key ingredient in urban smog. The research offers insight into the earliest stages of pollution formation and could help improve air quality forecasting ...
Phys.org / Gut bacteria mostly compete—but cooperation finds a way
Understanding how bacteria influence one another is essential for understanding how microbial communities are formed and maintained. Researchers at Umeå University have now systematically mapped interactions between common ...
Tech Xplore / Frontier AI access is a growing national security question for the UK
Two recent events should dramatically alter thinking and decision-making about the use of overseas AI models in the UK's critical national infrastructure, argues a new white paper from the University of Surrey. First, the ...
Phys.org / Fossil-fuel carbon fingerprint reaches the deep North Atlantic
The use of fossil fuels alters both the concentration and the carbon isotope composition of carbon dioxide in the atmosphere. Since surface water exchanges carbon dioxide with the atmosphere, this also alters the isotopic ...
Medical Xpress / Temperature extremes can increase risk of heart failure hospitalization, study shows
Heart failure hospitalization risk increases after short-term exposure to cold spells, lower ambient temperatures and higher ambient temperatures, according to a study published in JACC and presented at ESC Congress 2026. ...
Phys.org / Using plutonium to probe the universe: Magneto‑ν experiment advances dark matter and neutrino research
Astronomers can't see dark matter directly, but they know it's there: Its gravity shapes galaxies and the large-scale structure of the cosmos. In an effort to uncover the composition of this hidden mass, a team at Lawrence ...
Phys.org / For Legionella bacteria, taking over a cell means playing by its rules
When it comes to invading healthy cells, Legionella bacteria rely on blending in rather than breaking in. New research from Van Andel Institute scientists demonstrates how a protein produced by Legionella mimics the behavior ...
Medical Xpress / First-in-human pilot trial improves stem cell collection and delivery for sickle cell gene therapy
Patients with sickle cell disease are often hesitant to undergo transformative gene therapy—the current lengthy process requires multiple hospital visits to collect enough stem cells. Researchers from Boston Children's Hospital ...
Phys.org / How chromosomes find their partners
For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of barcode, enabling the correct ...
Phys.org / Evolution favors flatter paths when fitness outcomes are equal, study finds
A surprising discovery by Technion researchers sheds new light on the dynamics of evolution. Published in the Proceedings of the National Academy of Sciences, the study shows that when an organism has several evolutionary ...
Medical Xpress / Digital pets boost daily activity by more than 20%, trial finds
According to a master's thesis at the Norwegian University of Science and Technology (NTNU), a mobile game can make physical activity more enjoyable. Two master's students investigated how the mobile game "BitPet" affects ...
Medical Xpress / Gut bacteria may communicate differently with the human body in patients with Parkinson's disease
A new study from the University of Oulu suggests that gut bacteria may send different biological signals in Parkinson's disease. The findings add to growing evidence that changes in the gut could be linked to Parkinson's ...
