In steganography, an ordinary message masks the presence of a secret communication. Humans can never do it perfectly, but a new study shows it's possible for machines.
Several areas of physics suggest reasons to think that unobservable universes with different natural laws could lie beyond ours. The theoretical physicist David Kaplan talks with Steven Strogatz about the mysteries that a multiverse could solve.
Digging for Buried Baryons The missing baryon puzzle asks where all the ordinary (not dark) matter is hiding in the universe. While some astrophysicists have declared the puzzle solved, others are scouring the cosmos for the last bits of baryonic matter, reports Nathan Collins for Symmetry Magazine. In 2018, a large trove of previously overlooked baryonic matter was found in the warm tendrils of gas in the space between galaxies. Katia Moskvitch wrote about the discovery for Quanta and how it helped solve the missing baryon puzzle.
Complexity in the Yeast Likely of Places Life has repeatedly evolved from unicellularity to multicellularity — and it can happen much more suddenly than was thought possible. Selection pressures led cultures of laboratory yeast to evolve multicellular forms in just a couple of years, reports Ed Yong for The Atlantic. The researchers imposed selection pressure on the yeast by depriving it of oxygen, which made larger, multicellular clumps more favorable. Veronique Greenwood reported on their study for Quanta when a preprint of the work was posted in 2021.
