Horse-riding Scythian herders and warriors, who inhabited Central Asia and Eastern Europe around 2,500 years ago, may have had cultural roots several thousand kilometers to the east in Siberia, a new study suggests (SN: 7/27/23). Remains of at least one person and 18 horses found atop a roughly 2,800-year-old tomb in southern Siberia may come […]

Dozens of fugitive stars were caught fleeing a dense star cluster in a satellite galaxy of the Milky Way. The swarm of speeding stars could mean that such runaways had a bigger influence on cosmic evolution than previously thought, astronomers report October 9 in Nature. Massive stars are born in young clusters, packed so close […]

Cancer-destroying particle beams have been caught red-handed. Particle beams can deliver a burst of destructive energy directly to tumors – assuming the beam is in the right place. Now, using a radioactive beam, scientists have determined the location of the beam while treating tumors in mice. It is the first successful treatment of tumors with […]

One of the most distant quasars known appears to have shut down the formation of new stars in all galaxies in its vicinity. A quasar is a powerful source of light created by hot gas swirling around a supermassive black hole at the center of a galaxy. Intense radiation from a quasar, called VIK J2348-3054, […]

Contrary to a previous report, there is no evidence for an intermediate-mass black hole in Omega Centauri, the Milky Way’s most massive and luminous globular star cluster, a new study finds. Instead, a hive of much smaller black holes dipping in and out of the tightly packed star cluster could explain the motion and distribution […]

Extreme Climate Survey Scientific news is collecting questions from readers about how to navigate our planet’s changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? Most “radiant cooling” designs involve roofs designed to receive and then emit the sun’s energy in infrared wavelengths that […]
