Insight into cells' 'self-eating' process could pave the way for new dementia treatments
Cells regularly go through a process called autophagy — literally translated as 'self-eating' — which helps to destroy bacteria and viruses after infection. Now new research has shed light on the mechanisms behind autophagy and how it progresses — particularly relating to a process called liquid-liquid phase separation (LLPS).

Astronomers Find 8 Repeating Radio Bursts From Deep Space
The universe is rife with mysteries, but few are as perplexing as fast radio bursts (FRBs). These distant, highly energetic radio-frequency flashes were only discovered in 2007, and most observations have come from non-repeating sources. That makes it hard to study the phenomenon in detail. Astronomers knew of just a few repeating signals before, but a team of researchers reports the discovery of
