Cosmic ‘lenses’ will better define dark matter

Cosmic ‘lenses’ will better define dark matter

Physicists Bryce Wedig and Tansu Daylan, in Arts & Sciences, calculated how many gravitational lenses will be uncovered by NASA’s Nancy Grace Roman Space Telescope when it begins science operations in 2027. By examining a large population of these lenses, the researchers hope to learn a lot more about the mysterious nature of dark matter.

Copycat evolution

Copycat evolution

Biologist Jonathan Losos, in Arts & Sciences, has documented evidence of a kind of “copycat” evolution between extremely short-faced breeds of cats and dogs. Generations of intentional breeding have led these animals to converge on a rounded, flat-nosed head shape that humans prefer — even though the shape causes a variety of health ailments.
