When galaxies collide: Models suggest galactic collisions can starve massive black holes
It was previously thought that collisions between galaxies would necessarily add to the activity of the massive black holes at their centers. However, researchers have performed the most accurate simulations of a range of collision scenarios and have found that some collisions can reduce the activity of their central black holes. The reason is that certain head-on collisions may in fact…

Scientists Use Satellite Imagery To Count Elephants
Scientists from a trio of universities have combined satellite imagery with deep learning to detect elephants from space. The goal is to help protect these endangered species from poachers or habitat destruction. Their study was published in the journal Ecology and Conservation. Interesting Engineering reports: The team’s method proved comparable to human detection accuracy and could help solve a number of…
Researchers discover the earliest supermassive black hole and quasar in the universe
Nearly every galaxy hosts a monster at its center—a supermassive black hole millions to billions times the size of the Sun. While there’s still much to learn about these objects, many scientists believe they are crucial to the formation and structure of galaxies. What’s more, some of these black holes are particularly active, whipping up stars, dust and gas into glowing…
Report: US Halts Huawei’s Suppliers, Including Intel, in Last Blow to China’s 5G
“The Trump administration notified Huawei suppliers, including chipmaker Intel, that it is revoking certain licenses to sell to the Chinese company and intends to reject dozens of other applications,” Reuters reports, citing sources familiar with the matter: One of the sources said eight licenses were yanked from four companies. Japanese flash memory chip maker Kioxia Corp had at least one license…
