All-photonic quantum repeaters could lead to a faster, more secure global quantum internet

Posted by in categories: engineering, internet, quantum physics

Engineering researchers have demonstrated proof-of-principle for a device that could serve as the backbone of a future quantum Internet. University of Toronto Engineering professor Hoi-Kwong Lo and his collaborators have developed a prototype for a key element for all-photonic quantum repeaters, a critical step in long-distance quantum communication.

The American Public Increasingly Desires Life Extension

Posted by in categories: biotech/medical, life extension

Attitudes about life extension have significantly changed within the last decade.

While medical schools have had the idea that aging should be brought under medical control for over a century, the explicit desire to greatly extend one’s life remained rare – until very recently. A new study by YouGov, a market intelligence company that researches multiple topics, found that, today, one in five Americans agrees with the statement “I want to live forever.” Is this the result of some sort of bias, or does it mean that we are reaching a turning point, after which society will start boldly and unambiguously clamoring for the cure for aging?

The desire for a long life

In test of wisdom, new research favours Yoda over Spock

Posted by in category: futurism

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.

Stress and dream sleep are linked to pathways of brain cell death and survival

Posted by in categories: food, neuroscience

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.

Design and Clinical Evaluation of the Interoperable Artificial Pancreas System (iAPS) Smartphone App: Interoperable Components with Modular Design for Progressive Artificial Pancreas Research and Development

Posted by in categories: biotech/medical, information science, mobile phones

#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.
