Researchers have developed a scalable method for creating large numbers of quantum light sources on a chip with unprecedented precision that not only could pave the way for the development of unbreakable cryptographic systems but also quantum computers that can perform complex calculations in seconds that would take normal computers years to finish. Household lightbulbs give off a chaotic torrent of energy, as trillions of miniscule light particles – called photons – reflect and scatter in all directions...

Blue asteroids are rare, and blue comets are almost unheard of. An international team led by Teddy Kareta, a doctoral student at the University of Arizona’s Lunar and Planetary Laboratory, investigated (3200) Phaethon, a bizarre asteroid that sometimes behaves like a comet, and found it even more enigmatic than previously thought.

Kareta presented the results during a press conference on Oct. 23 at the 50th annual meeting of the American Astronomical Society’s Division for Planetary Science in Knoxville, Tennessee. Using telescopes in Hawaii and Arizona, the team studied sunlight reflected off Phaethon, which is known to be blue in color...

Summary of the pathways impacted by chronic BP3 treatment in liver and WAT in obese mouse models. BP3 enhances FGF/FGFR signaling and downstream activation of Akt and IL6/Stat3 that lead to the inhibition of gluconeogenesis, through Ppargc1a/G6pc downregulation. The parallel activation of Akt and Stat3 results in an inhibition of Ppargc1b and/or Srebf1, key regulators of downstream lipogenic enzymes, thus leading to the inhibition of de novo lipogenesis and TG synthesis.

To the great surprise of cancer researchers, a protein they investigated for its possible role in cancer turned out to be a powerful regulator of metabolism...

Scientists’ method quenches lithium metal dendrites in batteries that charge faster, last longer. Rice University scientists are counting on films of carbon nanotubes to make high-powered, fast-charging lithium metal batteries a logical replacement for common lithium-ion batteries.

The Rice lab of chemist James Tour showed thin nanotube films effectively stop dendrites that grow naturally from unprotected lithium metal anodes in batteries. Over time, these tentacle-like dendrites can pierce the battery’s electrolyte core and reach the cathode, causing the battery to fail...
