Medical Xpress / ADHD medication in childhood may reduce later psychosis risk, study finds
A new study, led by scientists at University College Dublin and the University of Edinburgh, has found that commonly prescribed attention deficit hyperactivity disorder (ADHD) medication in childhood may lower the long-term ...
Phys.org / Low-cost sensor system could warn farmers of salt stress in plants
Soil salinity is a critical concern in agriculture when excessive soluble salts restrict a plant's water uptake, according to the U.S. Department of Agriculture, hindering crop growth and reducing yields on roughly 30% of ...
Phys.org / Bioelectronic platform enables precise H₂S delivery to cells, turning a toxic gas into a therapeutic tool
A toxic gas known for its "rotten egg smell" has been transformed into a therapeutic tool. A research team at KAIST has developed a technology to precisely control hydrogen sulfide (H2S) using electrical signals, bringing ...
Phys.org / Now you see it, now you don't: Material can transition between quantum states
A team of scientists led by the U.S. Department of Energy's (DOE) Argonne National Laboratory has identified a rare, switchable quantum property in a new type of nickel sulfide material. The discovery could have applications ...
Phys.org / NASA X-ray mission gets fresh look at 2,000-year-old supernova
NASA's IXPE (Imaging X-ray Polarimetry Explorer) mission has taken a new observation of a supernova, RCW 86, helping fill in a fuller picture of what other telescopes have observed.
Phys.org / World Food Prize goes to food safety scientist for preventing millions of cases of foodborne illness
A scientist who pioneered the modern food processing safety standards used around the world was awarded this year's World Food Prize, the organization announced Wednesday, crediting his work for averting millions of cases ...
Phys.org / Tiny fossil eggs provide first physical evidence of Cretaceous bird-like dinosaurs in Korea
A major gap in South Korea's prehistoric record has been filled with the discovery of Onggwanoolithus aphaedoensis, the first known bird-type dinosaur eggs from the Cretaceous period of South Korea. The find, which is detailed ...
Phys.org / Radio signals at the edge of extreme stars come from far beyond their surfaces
Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams that sweep across the ...
Phys.org / Unusual signal may prove existence of primordial black holes
It may well take years to prove, but a pair of University of Miami astrophysicists could be on the verge of a cosmic breakthrough that will confirm the existence of primordial black holes and the role they play in one of ...
Tech Xplore / A robotic hand without motors? How a sub-second shape-shifting actuator could work
While space structures and robotic arms require lightweight actuation devices capable of repetitive movement, conventional motor-based systems face limitations due to their heavy weight and complex structures. A KAIST research ...
Tech Xplore / 'Spin-flip' in metal complexes opens a path beyond solar cell efficiency limits
In the fight against climate change, solar power is a promising alternative to fossil fuels. Every second, Earth receives an enormous amount of energy from the sun. Yet solar cells capture only a fraction of it, constrained ...
Phys.org / Polymer uses movable molecular rings to overcome durability–degradability trade-off
Modern polymer materials face a fundamental challenge: they must remain strong and durable during use, yet ideally degrade when they are no longer needed. Designing materials that satisfy both requirements has long been a ...
