Phys.org / Rising CO₂ and warming jointly limit phosphorus availability in rice soils, decade-long study reveals
A decade-long study has revealed that rising atmospheric CO₂ and warming work together to reduce the availability of phosphorus in rice-upland crop rotation systems, potentially threatening future food security. The research, ...
Tech Xplore / AI and brain control: New system identifies animal behavior and silences responsible neurons in real time
A male fruit fly in a laboratory chamber extends his wings and vibrates them to produce his species' version of a love song. A female fly stays nearby listening. Suddenly, a green light flashes across the chamber for a fraction ...
Phys.org / Elevated lead levels could flow from some US drinking water kiosks
After high-profile water crises like the one in Flint, Michigan, some Americans distrust the safety of tap water, choosing to purchase drinking water from freestanding water vending machines or kiosks. Yet this more expensive ...
Tech Xplore / Turning down the heat: Researcher identifies better way to remove heat from AI data centers
A University of Houston professor has taken on the global challenge of reducing the staggering amount of heat generated in artificial intelligence data centers. Hadi Ghasemi, J. Willard Gibbs Distinguished Professor of Mechanical ...
Phys.org / Satellite record shows boreal forests expanded 12% and shifted north since 1985
The boreal forest—the world's largest terrestrial biome—is warming faster than any other forest type. To understand the changing dynamics of boreal forests, Min Feng and colleagues analyzed the biome from 1985 to 2020, ...
Phys.org / Bird guano powered rise of Chincha Kingdom in Peruvian Andes, archaeologists find
New archaeological evidence reveals that seabird guano—nutrient-rich bird droppings—was not only essential to boosting corn yields and supercharging agriculture in ancient Peru, but it may have been a driving force behind ...
Phys.org / Pulsar timing hints at a nearby dark matter 'sub-halo'
A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar neighborhood. Reporting their findings in Physical Review Letters, a team led by Sukanya Chakrabarti ...
Medical Xpress / HPV cancer vaccine slows tumor growth and extends survival in preclinical model
Throughout the past decade, Northwestern University scientists have uncovered a striking principle of vaccine design: Performance depends not only on vaccine components but also on vaccine structure. After proving this concept ...
Phys.org / Lahontan Basin cave burials 'neither rare nor uncommon,' says new study
In a study published in American Antiquity, Dr. David Madsen and his colleagues address the proposition that the lower Lahontan drainage basin (LLDB), located in the Intermountain West, is "unique" for the use of caves and ...
Phys.org / Strike against mask wearing in 1930s echoed COVID-19 protests, study finds
New research from The University of Manchester has shown that debates and resistance about wearing face masks go back a lot further than the COVID-19 pandemic. Dr. Meng Zhang, a Wellcome Trust Research Fellow at the University's ...
Tech Xplore / What chatbots can teach humans about empathy
Over half of U.S. adults are using large language models (LLMs)—such as ChatGPT, Gemini and Copilot—in some capacity. Whether using artificial intelligence to create grocery lists, turn oneself into a Muppets character ...
Tech Xplore / Robots use radio signals and AI to see around corners
Penn Engineers have developed a system that lets robots see around corners using radio waves processed by AI, a capability that could improve the safety and performance of driverless cars as well as robots operating in cluttered ...
