Phys.org / Study finds park design affects cooling differently by day and night
Urban parks are often seen as natural refuges from summer heat, but new Concordia research shows that, depending on the time of day, the way trees are arranged within parks can influence whether those spaces cool people down ...
Phys.org / High school student designs low-cost teabags to remove arsenic from water and help millions
Arsenic contamination in drinking water is a global issue, with over 200 million people estimated to be at risk. While water treatment plants remove the metal, the problem persists in low-resource areas or undertreated well ...
Phys.org / CRISPR variant selectively targets tumor DNA
Cancer cells excel at evading detection, but subtle chemical differences set them apart from healthy cells. Now, a team of scientists from Wageningen University & Research and Van Andel Institute has identified a way to exploit ...
Phys.org / 'Bathtub ring' hints at ancient Martian ocean
Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet's surface. The research was conducted by former Caltech postdoctoral ...
Phys.org / A backyard bug repellent is derailing bumblebees' ability to navigate
In the summer, many people turn to mosquito repellents to reduce the insects' buzzing and bites. One solution that has become increasingly popular in recent years is the Thermacell device, which releases vaporized, pyrethroid-based ...
Phys.org / Toothy snout recasts Australia's famed Muttaburrasaurus as a picky eater
In a surprising new study, Australia's most famous plant-eating dinosaur has been described as a "picky eater with a nose for good food" when it roamed across the continent around 96 million years ago. After examining different ...
Tech Xplore / Making AI safer for victims of intimate partner violence
Conversational AI tools denied blunt requests for harmful content by researchers posing as intimate partner abusers, but these guardrails were easily circumvented when they requested the content under false pretenses, a new ...
Phys.org / Alien life may hide in plain sight: Statistical patterns across exoplanets move beyond traditional biosignatures
A research team has developed a new approach to detecting life beyond Earth that does not rely on identifying specific biological markers. Instead, the study suggests that life may be detectable through patterns emerging ...
Phys.org / New metric identifies at-risk mangroves before they disappear
Scientists from UC San Diego's Scripps Institution of Oceanography and the Centro para la Biodiversidad Marina y la Conservación in Mexico have developed a tool that identifies mangrove patches facing the greatest risk of ...
Phys.org / Simulations generate thousands of cyclone scenarios to predict extreme flooding in Bay of Bengal
Powerful cyclones can push seawater miles inland, threatening densely populated communities and critical infrastructure built along coastal areas. A combination of exposure and complexity makes the Bay of Bengal in Southeast ...
Phys.org / Subaru telescope captures comet 3I/ATLAS composition change
The Subaru Telescope observed the interstellar comet 3I/ATLAS on January 7, 2026, after it made its closest approach to the sun. By observing colors in the coma around the comet, astronomers could estimate the ratio of carbon ...
Tech Xplore / Computational 'time machine' shows solar and wind power on track for 2°C target, but not for 1.5°C
Wind and solar power have grown faster than almost anyone predicted, but projecting their future expansion remains surprisingly difficult. Researchers at Chalmers University of Technology, Sweden, have developed what they ...
