Huge eruption on a distant star confirmed at last

00:45 A coronal mass ejection from a distant star

Researchers have detected what they say is the strongest evidence yet of a coronal mass ejection (CME) coming from a star other than our Sun. CMEs are massive bursts of fast-moving plasma that can be detected thanks to the characteristic radio signal they produce. However, despite decades of searching, these signals have only been identified from the Sun. Now a team has identified a similar signal coming from a distant star in the Milky Way. They hope their discovery will lead to better understanding of the impact these colossal events might have on the atmospheres of exoplanets, and their chances of being habitable.

14:29 The rare genetic variants that may increase the risk of ADHD

Attention-deficit/Hyperactivity disorder (ADHD) is a condition that affects around 1 in 20 young people, but its underlying causes are not fully understood. Now, a team of researchers show that three rare genetic variants are implicated in an increased risk of ADHD, which may play a role in the neurons involved in dopamine signalling. While this work provides a better understanding of the complex genetics at play, the authors caution more research is needed to unpick the complex interplay other factors involved in ADHD.
