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 ...
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 ...
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 ...
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 ...
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 ...
Phys.org / Evidence of cosmic-ray acceleration from a nearby supernova remnant
Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football (soccer ball) being kicked ...
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 / Nanofiber implant delivers three drugs, doubles survival in glioblastoma mice
Researchers with the University of Cincinnati and Johns Hopkins Medicine developed a potential treatment for brain cancer that uses nanofibers embedded with a combination of drugs that work in concert to target tumors. The ...
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 ...
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, ...
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.
