Phys.org / Quantum light gives a 20-fold boost to ultrafast laser processes
Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but pushing these processes to their limits has long been hampered by a fundamental constraint: the stronger ...
Medical Xpress / How a remarkable trial on bedrest during the Korean War led to evidence‑based medicine
In 1959, a young doctor named David Sackett stumbled on a clinical trial that would change his life—and most of ours. The study showed that conventional wisdom on bed rest in medicine was wrong. And it helped lead Sackett ...
Phys.org / Is extracting oxygen from lunar soil the future of space exploration?
A new race to the moon is emerging between the United States and China. Unlike fifty years ago, the goal is no longer just about landing and leaving, but establishing a base that allows for a sustainable presence and extended ...
Phys.org / Inside Europe's largest Copper Age tomb, children's bones expose an ancient health crisis hidden for 5,000 years
Nearly 5,000 years ago, respiratory infections, possibly including tuberculosis, were ravaging the children buried at Camino del Molino (CMOL), Spain. The massive circular burial cave carved into rock is Europe's largest ...
Phys.org / Pulsar wind nebula inside supernova remnant explored with Chandra
Astronomers from the George Washington University (GWU) in Washington, DC, and elsewhere have employed NASA's Chandra X-ray spacecraft to observe a pulsar wind nebula inside a supernova remnant known as CTA 1. Results of ...
Medical Xpress / Inside Alzheimer's neurons, tau may set off a genetic chain reaction that ends in cell death
Alzheimer's disease is a neurodegenerative disease characterized by a progressive decline in mental functions and memory loss. Along with frontotemporal dementia and some other neurodegenerative disorders, Alzheimer's disease ...
Tech Xplore / Tabletop 3D printer cuts semiconductor 3D patterning from days to minutes
Faculty in the Cockrell School of Engineering have developed a rare printer as part of a larger project to speed up production and lower costs of manufacturing semiconductors critical to modern electronics.
Medical Xpress / AI repurposes routine chest X-rays to catch silent bone loss before fracture
Osteoporosis is a silent disease where bone loss develops gradually before fractures occur. Current clinical screening recommendations mainly focus on older women and selected high-risk groups, leaving some men, younger adults, ...
Science X / When Earth went dark after Chicxulub, tiny ocean dwellers held the secret to survival
When a 10-kilometer asteroid struck Earth 66 million years ago, the planet was plunged into darkness—and about 75% of species vanished, including marine life. Now, a new study reveals that the planetary effects from the impact ...
Medical Xpress / Why some chikungunya virus infections may turn chronic
Chikungunya virus, which is transmitted to people by infected Aedes mosquitoes and characterized by high fever and intense joint swelling and pain, has made a resurgence in many countries around the world in recent years.
Tech Xplore / 3D silicon circuits bring denser computer chips closer to reality
By stacking transistors on top of one another, rather than laying them side by side on a flat chip, many electronic engineers are hopeful that vast amounts of computing power could be packed into tiny spaces, all while cutting ...
Phys.org / Rainfall near 700 mm marks turning point in ecosystem nitrogen retention
In a study published in Nature Geoscience, a research team led by Prof. Liu Lingli from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has identified a mean annual precipitation (MAP) threshold of approximately ...
