This makes me worried about undersleeping. đ
New study suggests chronic sleep-deprivation causes overactivity in the brainâs self-cleaning mechanism, leading to the destruction of healthy cells.

In some ways, learning to program a computer is similar to learning a new language. It requires learning new symbols and terms, which must be organized correctly to instruct the computer what to do. The computer code must also be clear enough that other programmers can read and understand it.
In spite of those similarities, MIT neuroscientists have found that reading computer code does not activate the regions of the brain that are involved in language processing.
Instead, it activates a distributed network called the multiple demand network, which is also recruited for complex cognitive tasks such as solving math problems or crossword puzzles.
A questionnaire developed by XPRIZE and Deep Longevity claims to be able to accurately predict your psychological age by using artificial intelligence (AI) to analyze your answers, which theoretically should fall close to your chronological age. The questionnaire is developed from a study published in Aging that used AI in an attempt to identify key hallmarks of psychological aging and the top risk factors that affect mortality.
While the questionnaire seems like a fun insight into whether youâre an old soul or a young gun at heart, there is an important scientific basis for an age-predicting AI. The newly developed technology represents the first AI aimed solely at using psychological aspects to predict age. The researchers hope it can contribute to understanding the role psychological clocks play in overall aging, as well as improving mental health and the feeling of youth.
âFor the first time, AI can predict human psychological and subjective age and help identify the possible interventions that can be applied in order to help people feel and behave younger,â said Alex Zhavoronkov, PhD, founder and CLO of Deep Longevity and co-author of the study, in a statement.
The single-celled organism behind the infections is usually found in warm bodies of freshwater, including lakes and rivers. Once a person is infected â an exceedingly rare occurrence usually resulting from swimming or diving in infected waters â the amoeba travels from the nose into the brain.
Once there, the organism can kick off a nasty brain condition called primary amebic meningoencephalitis (PAM). And yep, according to the CDC, PAM is âusually fatal.â
The good news: there have only been 34 infections reported in the US in the last ten years, according to CDC data.
Summary: Researchers have identified a direct cellular interaction between the nervous system and the immune system. Pain sensing neurons around the lymph nodes can modulate lymph node activity.

The nervous and immune systems have long been thought to be separate entities in the body, but new research has uncovered a direct cellular interaction between the two. Scientists from Harvard Medical School, the Broad Institute of MIT and Harvard, MIT, and the Ragon Institute of MGH, MIT and Harvard have found that pain-sensing neurons surround lymph nodes in mice, and can modulate the activity of these small organs, which are key parts of the immune system.
Summary: YKL-40 may be a key player in circadian rhythm disruptions associated with Alzheimerâs disease.

Fractured sleep, daytime sleepiness and other signs of disturbance in oneâs circadian rhythm are common complaints of people with Alzheimerâs disease, and the problems only get worse as the disease progresses. But the reason for the link between Alzheimerâs and circadian dysfunction is not well understood.

People who have meditated for thousands of hours exhibit a remarkable difference in their brainwaves. Psychologist and author Daniel Goleman says we can actually see what happens in the heads of those who have achieved âenlightenmentâ and the results are unprecedented in science.

All the same, Schroepfer seemed to acknowledge that getting people to actually use the tech might be a hard sell, according to the leaked meeting audio acquired by BuzzFeed News.
âWe have to build responsibly to earn trust and the right to continue to grow,â Schroepfer said. âItâs imperative that we get this right so that people around the world get all these amazing technologies⊠without experiencing the downsides.â
