Marine heatwaves becoming more intense, more frequent
When thick, the surface layer of the ocean acts as a buffer to extreme marine heating--but a new study from the University of Colorado Boulder shows this ''mixed layer'' is becoming shallower each year. The thinner it becomes, the easier it is to warm. The new work could explain recent extreme marine heatwaves, and point at a future of more frequent and destructive ocean warming events as global temperatures continue to climb. (2021-01-28)

Crystal structures in super slow motion
Laser beams are used to change the properties of materials in an extremely precise way.

The results were published in Science. (2021-01-22)

Many junior doctors feel out of their depth with the end-of-life decisions faced during COVID-19 pandemic
In normal times, end-of-life care discussions are most commonly led by senior doctors. However, new research from a busy London hospital shows that the high numbers of deaths taking place in hospitals during the COVID-19 pandemic, frequently out-of-hours, is leading to junior (foundation level) doctors having to lead on these difficult discussions with families, often with no formal experience or training.
