Phys.org / Ultrafast laser pulses reveal a material's hidden state of matter
What would it take to instantly transform a material from an electrical insulator into a conductive state without ever touching it? Using ultrafast laser pulses and powerful X-rays, scientists at the National Synchrotron ...
Phys.org / Chemists reveal one-step 'alkyl swap' that rewrites key amines for drug discovery
For more than a century, chemists have been building complex molecules step by step—bond by bond, atom by atom. But what if, instead of painstakingly reassembling molecules, they could be directly "rewritten"? This is exactly ...
Medical Xpress / Study: Food security varies widely across US ethnic groups
American Indians and Alaska Natives living below the poverty line face sharply higher rates of food insecurity than other impoverished adults—nearly 4 in 10 lack consistent access to a healthy diet.
Phys.org / Are alien probes hiding in our backyard? A new study says we've barely looked
Even at this early stage in our spacefaring age, humanity has already begun sending probes that will eventually reach other solar systems, even if that was not their original intention. Five robotic explorers—Pioneer 10 and ...
Dialog / When less is more: Scaling law explains why ultrathin materials get stronger as they get thinner
One of the most fascinating aspects of physics is that nature often behaves in ways that seem completely counterintuitive. A good example comes from ultrathin materials. If I take a sheet of material and make it thinner ...
Medical Xpress / Can use of popular weight loss medications reduce behaviors linked to violent crime?
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are widely prescribed for diabetes and obesity, but studies have found evidence that the medications may also influence behavior, such as supporting impulse control and ...
Medical Xpress / Teens' attitudes toward smoking are shaped more by dad's habits than mom's
A new study from the University of Nebraska–Lincoln sheds light on how parental smoking shapes adolescents' attitudes and use of both traditional cigarettes and e-cigarettes, finding that fathers' behaviors may play a more ...
Phys.org / Electron matter waves gain ultrafast torque that flips handedness in femtoseconds
Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very small scales. In quantum mechanics, particles exhibit both particle-like and wave-like behaviors, ...
Phys.org / Human evolution was messy and gradual, not an abrupt revolution, argues archaeologist
It is generally accepted by archaeologists that modern humans originated in Africa and dispersed worldwide, while other hominins went extinct. Yet how and when Homo sapiens dispersed out of Africa, and whether it was an abrupt ...
Tech Xplore / Nanoengineered wood sets new record for transformer insulation
The world's power grid is straining under the surge in electricity demand from data centers, electric vehicles and renewable energy. And a century-old technology, the power transformer, must support this dramatic increase. ...
Phys.org / Digital tools reveal hidden extinctions as AI reshapes global conservation
In a seismic shift since Kew's inaugural State of the World report 10 years ago, the sixth State of the World's Plants and Fungi report, published June 16, 2026, brings together expertise from more than 400 scientists across ...
Phys.org / Chimpanzees react negatively to unfairness, especially when close partners are nearby
Primates, including humans, are among the social animals living on Earth. Their survival relies heavily on cooperation with others, alliances, the sharing of resources and other social interactions.
