Phys.org / Terahertz light from superconducting stripes
Why do some materials carry electrical currents without any resistance only when cooled to near absolute zero while others do so at comparatively high temperatures? This key question continues to vex scientists studying the ...
Phys.org / Computer simulations visualize how an essential stem cell protein opens wrapped DNA
A key protein for converting adult stem cells into cells that resemble embryonic stem cells has been visualized in unprecedented detail by an international team of researchers around Hans Schöler and Vlad Cojocaru of the ...
Phys.org / What will replace climate warming HFCs in refrigerators and air conditioners?
The U.S. Senate voted to ratify an international treaty on Sept. 21, 2022, and join 137 other countries in agreeing to phase out a class of climate-warming chemicals that are widely used as coolants in refrigerators, air ...
Medical Xpress / Botox influences the control of emotions in the brain
The bacterial toxin botulinum toxin (BTX)—colloquially known as Botox—is probably known to most people as a remedy for wrinkles. But botulinum toxin can do even more: if it is injected into the forehead, for example, it can ...

Phys.org / How to prepare for the next extreme heat wave now
Summer is over, but memories of the season's historic heat waves are burned into our consciousness.
Tech Xplore / In the face of drought, hydropower still delivers electricity
In 2022, a quick internet search for Lake Mead or Lake Powell returns startling images of drying lake beds and parched land.
Phys.org / Wrapping of nanosize copper cubes can help convert carbon dioxide into other chemicals
As the need to mitigate climate change accelerates, scientists are trying to find new ways to reduce carbon dioxide emissions. One process, called electrochemical reduction or electrolysis, uses electricity and a catalyst ...
Phys.org / JPSS-2 begins launch processing
Preparations are looking up for the launch of the National Oceanic and Atmospheric Administration's (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite. On behalf of NOAA, NASA develops and builds the instruments, spacecraft, ...
