Around the Web

Do Look Up
Scientists have designed a new algorithm to sift through telescope images for new asteroids, reports Kenneth Chang for The New York Times. Keeping track of asteroids is especially important in our current era. In 2019 Joshua Sokol wrote for Quanta about how studying lunar craters revealed that the last 300 million years have been particularly violent, with more frequent asteroid collisions.


Rapid Evolution
A large-scale study of 19 different animal populations over more than a decade reveals that natural selection is happening 2 to 4 times faster than previously thought, reports Qamariya Nasrullah for Cosmos Magazine. Evolution can occur surprisingly quickly over short timescales, but sometimes these rapid short-term changes cancel out over the long run, as Carrie Arnold wrote for Quanta in 2017.
