Phys.org / Insects in the tropics are already near their heat limits. Climate change could push many beyond survival

Insects make up to 90% of all animal species on the planet, and most of them can be found in the tropics, the regions around the equator. Yet we still know surprisingly little about how these species will cope with rising ...

Phys.org / Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims

Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles ...

Phys.org / Astronomers find a third galaxy missing its dark matter, validating a violent cosmic collision theory

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the rotational spins of galaxies would force them to simply fly apart. But now, ...
