More than 60% of the water in a wood frog's body can freeze solid each winter: its heart stops, it stops breathing, and for more than 7 months it can lie essentially a frogsicle, before it thaws out in spring and simply hops away - Space Daily
Freezing solid is supposed to be the end. Ice forming inside a body generally stops the chemistry of life. For almost every animal on Earth, that is exactly how it works. The wood frog did not get the memo. Each winter, Rana sylvatica lets a large share of th…
For satellites as small as a briefcase, getting around in space just got a whole lot easier - Phys.org
MIT engineers are testing a new propulsion system that combines the power and speed of conventional chemical thrusters with the precision and fuel-efficiency of electrical thrusters. The system could enable the design of nimbler, more flexible small satellite…
Massive Booms Shook the East Coast for over 300 Years. Scientists Finally Found the Source of the Sonic Explosions. - Yahoo
The cannon-like sound could be heard for hundreds of miles, but its cause long remained a mystery.
Scientists Think a Cosmic Particle Accelerator Shot a Mystery Particle Right at Earth - Yahoo
A gigantic “blazar” may have fired a beam of light-speed particles at our planet, creating a 2023 “ghost particle” detection.
Molecular glasses solve long-standing Arrhenius paradox - Phys.org
Glasses are non-crystalline but solid states of matter in which molecules and atoms are not arranged into a regular crystal lattice, but rather in a disordered pattern. Glassy materials are widely used in various settings, for instance, in the synthesis of ph…
Scientists Discover a Hidden Cause of Cellular Aging That Can Be Reversed - SciTechDaily
Scientists identified phosphatidylcholine loss as a key driver of mitochondrial aging and showed that restoring it can rejuvenate cellular energy networks.
