Contrary to what you may have been taught, water doesn't always freeze to ice at 32 degrees F (zero degrees C). Knowing, or controlling, at what temperature water will freeze (starting with a process called nucleation) is ...

(Phys.org)—A team of researchers with Donghua University in China has found a way to cause tiny (0.8 to 6 centimeter) objects made of graphene sheets to move around in specific ways using just heat and infrared light—and ...
Comet 46P/Wirtanen was releasing an unusual amount of alcohol as it made its historic flyby of Earth two and a half years ago. That's one of the findings from the latest published study comet detectives conducted after observing ...

(Phys.org)—It would seem that figuring out how many molecules of water are needed to form the smallest, or most basic ice crystal would have been discovered long ago, but that is not the case, because to measure both the ...
German researchers have discovered how natural antifreeze works to protect fish in the icy waters of the Arctic Ocean from freezing to death. They were able to observe that an antifreeze protein in the fish's blood affects ...
