En ny analys från Queen Mary University of London föreslår att universums fysiska konstanter befinner sig inom ett snävt intervall som tillåter vätskor att flöda korrekt inuti levande celler.
Forskare ledda av fysikern Kostya Trachenko argumenterar för att även små förändringar i värden som Plancks konstant eller elektronens laddning skulle förändra viskositeten tillräckligt för att störa näringstransport, proteinveckning och andra cellulära processer som krävs för liv.
Scientists at Brown University have proposed a topological explanation for why the cosmological constant remains small despite predictions from quantum field theory. The study connects quantum gravity to the quantum Hall effect. It was published recently in Physical Review Letters.

Researchers at Oregon Health & Science University have identified hidden fluid flows inside cells that rapidly transport proteins to the leading edge, challenging traditional views of cellular movement. The discovery, made during a classroom experiment, could explain why some cancer cells spread aggressively. The findings appear in Nature Communications.
NASA's upgraded Cold Atom Lab is back in operation aboard the International Space Station, enabling new research into quantum states of matter. The facility creates Bose-Einstein condensates at temperatures near absolute zero.
