Phys.org / Why is Europe the world's fastest warming continent?
Europe, which is in the throes of a record-smashing heat wave this week, is the world's fastest-warming continent and stretches into an even more rapidly heating Arctic.
Phys.org / Antihydrogen mirrors hydrogen in upgraded spectrum test, narrowing cosmic mystery
University of Calgary researchers are a part of a group who just got one step closer to solving a mystery of the universe. Dr. Timothy Friesen, Ph.D., an associate professor of Physics and Astronomy in the Faculty of Science, ...
Phys.org / 20,000 eyes on the universe
Think about a census. You could photograph every house in the country and produce a beautiful map, but without knocking on doors and asking questions, you'd know almost nothing about the people living in them.
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 / 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 / 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 ...
Phys.org / Why tipping fatigue is growing in Canada
Ever feel uncomfortable when a payment screen asks for a tip? We sure have. As tipping prompts become more widespread, more consumers are feeling uneasy or frustrated, but not always sure why.
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 ...
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 ...
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 / IceCube detects break in cosmic neutrino spectrum, ruling out simple power-law model
A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.
