Researchers have shown that ultracold atoms can be driven into a strange new quantum state called a fractional Fermi sea, where particles organize themselves in unexpected ways. The discovery points to a new phase of matter that goes beyond established quantum theories and could expand the possibilities of quantum simulation.

Two newly confirmed "super-puff" planets are so diffuse that they are less dense than cotton candy, despite being about the size of Jupiter. Their rare orbital relationship and enormous, lightweight atmospheres could provide valuable clues about how some of the strangest planets in the galaxy come to exist.

What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth. Drawing on the vastness of the universe and the likely existence of countless alien civilizations, they suggest it would be surprisingly Earth-centric to assume that only Earth-like biology can support conscious experience.
