First Ever Recording Of Dying Human Brain Shows Possible "Life Recall" Activity

Human brain activity in the final moments before death has been observed for the first time, revealing rhythmic activity comparable to those seen during dreaming.

It showed the sorts of waves that get going while dreaming, recalling memories, and processing information appeared to kick in during the brain’s final moments.

We Now Know Which Season The Dinosaurs Died, Says New Study

We’re identifying the time of year the dino-killing impact occurred with ever-increasing precision – the asteroid struck during springtime, a new study says.

Closest Extra-Galactic Fast Radio Burst Observed Might Also Be The Fastest

Radio astronomers have detected the closest repeating fast radio burst (FRB), a mysterious and very brief emission of radio waves whose origin continues to puzzle humanity. The detection comes from galaxy M81, a spiral galaxy less than 12 million light-years away – 40 times closer than the next closest FRB. There is still so much that we don’t about FRBs, how they form, and how they work. This work is important to the quest to understand these events and more.

Eating More Meat Associated With Higher Overall Cancer Risk

A study of almost half a million British adults has found low or no meat diets are associated with reduced overall cancer risk, including for cancers outside the digestive system. It's possible some other factor that co-varies with diet explains the lower rates of cancer. However, the researchers controlled for obvious possibilities like education, ethnicity, and cigarette and alcohol consumption, and found only marginal differences.
