Arthur Ashkin is the oldest person ever awarded a Nobel Prize. But he says he’s not done discovering yet. He still works every day.

Wise reasoning does not necessarily require uniform emotional control or suppression, says Igor Grossmann, professor of psychology at Waterloo and lead author of the new study. Instead, wise reasoning can also benefit from a rich and balanced emotional life.

A person’s ability to reason wisely about a challenging situation may improve when they also experience diverse yet balanced emotions, say researchers from the University of Waterloo.

The finding clarifies millennia of philosophical and psychological thinking that debates how wisdom is related to the effective management of emotionally charged experiences.

Monitoring their sleeping patterns, researchers identified an increase in the duration and continuity of REM sleep and specific brain oscillations characteristic of REM sleep, whereas ‘deep’ sleep, or non-REM sleep, did not change. The changes in REM sleep were very tightly linked to deficiency in the regulation of the stress hormone corticosterone. Mild stress also caused changes in gene expression in the brain.

The first and most distinct consequence of daily mild stress is an increase in rapid-eye-movement (REM) sleep, a new study in the journal PNAS reports. The research also demonstrated that this increase is associated with genes involved in cell death and survival.

REM sleep, also known as paradoxical sleep, is the sleep state during which we have most of our dreams and is involved in the regulation of emotions and memory consolidation. REM sleep disturbances are common in mood disorders, such as depression. However, little was known about how sleep changes are linked to molecular changes in the brain.

Next month SpaceX’s passenger capsule is expected to launch on an uncrewed mission—a big step towards bringing human spaceflight back to the US.

#OpenAccess #FullArticle The results of a new clinical trial have shown the safety and efficacy of the interoperable Artificial Pancreas System smartphone app (iAPS), which can interface wirelessly with leading continuous glucose monitors (CGM), insulin pump devices, and decision-making algorithms. The clinical trial and the app, which runs on an unlocked smartphone, are described in an article published in Diabetes Technology & Therapeutics (DTT), a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
