Pyrroloquinoline quinone disodium salt improves brain function in both younger and older adults†

Posted by in category: neuroscience

Brain function is important for a good quality of life. Pyrroloquinoline quinone disodium salt (PQQ) has been proven to improve brain function and cognition in older adults (above 45 years). In this double-blind, placebo-controlled study, we investigated the effects of PQQ on cognitive function in adults aged between 20 and 65 years. PQQ (20 mg per day) was administered for 12 weeks to the participants. After 12 weeks, the participants showed improvements in composite memory and verbal memory. A further age-stratified analysis was performed. In younger adults (aged 20–40 years), PQQ improved cognitive function (cognitive flexibility, processing speed, and execution speed) after 8 weeks. Only older adults (aged 41–65 years) showed improvements in complex and verbal memory after 12 weeks. In the logistic regression analysis that included the results of all cognitive tests, the changes due to PQQ intake were observed at 8 and 12 weeks in the young and old groups, respectively.

Facebook accounts hijacked

Posted by in category: futurism

A trojanized version of the legitimate ChatGPT extension for Chrome is gaining popularity on the Chrome Web Store, accumulating over 9,000 downloads while stealing Facebook accounts.

The extension is a copy of the legitimate popular add-on for Chrome named “ChatGPT for Google” that offers ChatGPT integration on search results. However, this malicious version includes additional code that attempts to steal Facebook session cookies.

The publisher of the extension uploaded it to the Chrome Web Store on February 14, 2023, but only started promoting it using Google Search advertisements on March 14, 2023. Since then, it has had an average of a thousand installations per day.

Researchers create self-sensing metamaterial concrete that produce power

Posted by in categories: life extension, materials

University of Pittsburgh.

A metamaterial is any material engineered to have a property that is elusive to naturally occurring materials. The research introduces the use of metamaterials in the creation of concrete, providing the option to alter its brittleness, flexibility, and shapeability to allow builders to use less of the material without sacrificing strength or longevity.

A.I. is ‘seizing the master key of civilization’ and we ‘cannot afford to lose,’ warns ‘Sapiens’ author Yuval Harari

Posted by in category: robotics/AI

Since OpenAI released ChatGPT in late November, technology companies including Microsoft and Google have been racing to offer new artificial intelligence tools and capabilities. But where is that race leading?

Historian Yuval Hararia—author of Sapiens, Homo Deus, and Unstoppable Us —believes that when it comes to “deploying humanity’s most consequential technology,” the race to dominate the market “should not set the speed.” Instead, he argues, “We should move at whatever speed enables us to get this right.”

Hararia shared his thoughts Friday in a New York Times op-ed written with Tristan Harris and Aza Raskin, founders of the nonprofit Center for Humane Technology, which aims to align technology with humanity’s best interests. They argue that artificial intelligence threatens the “foundations of our society” if it’s unleashed in an irresponsible way.

Time of day matters when it comes to cancer diagnosis and treatment, says metastasis study

Posted by in categories: biotech/medical, health

Your circadian rhythm doesn’t just govern your sleeping schedule; it can also impact cancer development, diagnosis, and treatment. In a review paper published in the journal Trends in Cell Biology, researchers discuss the role of circadian rhythms in tumor progression and spread and describe how we could better time when patients are tested for cancer and when they receive therapies to improve diagnostic accuracy and improve treatment success.

“The circadian rhythm governs most of the cellular functions implicated in cancer progression, and therefore its exploitation opens new promising directions in the fight against metastasis,” write the authors, molecular oncologists Zoi Diamantopoulou, Ana Gvozdenovic, and Nicola Aceto from the ETH Zurich in Switzerland.

Our circadian rhythms help our bodies synchronize different tasks throughout the day, including gene expression, immune function, and cell repair. We’ve long known that chronically disrupted circadian rhythms—as a result of erratic sleep patterns, jet lag, or , for example—can predispose us to a number of health issues, including cancer. More recent work has shown that circadian rhythms are not only involved in tumor onset, but also govern and metastasis, the colonization of secondary sites within the body.

“Godfather of artificial intelligence” weighs in on the past and potential of AI

Posted by in categories: government, robotics/AI

Hinton, who works with Google and mentors AI’s rising stars, started looking at artificial intelligence over 40 years ago, when it seemed like something out of a science fiction story. Hinton moved to Toronto, Canada, where the government agreed to fund his research.

“I was kind of weird because I did this stuff everyone else thought was nonsense,” Hinton told CBS News.

Grimes said she got a brain gadget for her birthday from a company competing with Elon Musk’s Neuralink

Posted by in categories: computing, Elon Musk, mathematics, media & arts, neuroscience, sustainability

Neurosity’s headset uses electroencephalogram technology, or EEG, to measure brain activity by placing small metal electrodes on a person’s scalp. If the electrodes detect decreased electrical activity in the brain, the Crown plays music and sounds, or pulses vibrations, hoping those actions will help the user focus.

But some developers, it seems, have taken Neurosity’s tech a step further, turning the Crown into a more traditional brain computer interface that can allow users to control a computer using only their mind.

One owner of the gadget claimed they’ve used it to drive a Tesla, moving the electric car short distances by doing some mental math, which signals to the device that the person wearing it is exerting a lot of cognitive effort.
