The ‘cannibal’ coronal mass ejection that devoured ‘dark eruption’ from the sun will crash into Earth tomorrow (July 18)

by

A coronal mass ejection (CME) launched by a solar flare (highlighted) on July 15. The CME subsequently cannibalized another previously launched CME on July 14 and is now heading straight for Earth. (Image credit: NASA/Solar Dynamics Observatory) A “cannibal” coronal mass ejection (CME) born of multiple solar storms, including a surprise “dark eruption,” is currently … Read more

Julia Gehrlein Department of Theoretical Physics, CERN, Geneva, Switzerland July 6, 2023• Physics 16, 20 The collider experiments have placed new direct limits on the existence of hypothetical heavy neutrinos, helping to define how ordinary neutrinos obtain their mass. Figure 1: In the see-saw mechanism, a hypothetical neutrino (left) is “mixed” with an observed neutrino … Read more

Deciphering the neutrino mass mystery A new approach uses random matrix theory

by
Neutrino concept

Scientists have used random matrix theory to demonstrate theoretically that the neutrino mass hierarchy can be explained mathematically. When a substance is fragmented into smaller and smaller segments, eventually, you reach a point where division is no longer possible. At this point, you are left with a building block. To date, 12 distinct elementary particles … Read more

Alzheimer’s: High levels of lean muscle mass may be protective

Share on PinterestHigher levels of lean muscle mass may also benefit brain health. Justin Lambert/Getty Images New research shows that high levels of lean muscle mass could help protect against Alzheimer’s disease. However, more research is needed to understand whether this connection is causal. To achieve lean muscle mass, experts recommend resistance exercise and a … Read more
