Scientists ‘control’ quantum light for the first time, achieving landmark

“We have taken a vital first step towards harnessing quantum light for practical use.”

Scientists have for the first time shown that they can control and distinguish tiny quantities of interacting photons — or packets of light energy — with high correlation, according to a study published in Nature.

This unprecedented accomplishment marks a significant turning point in the evolution of quantum technology, which could potentially advance quantum computing and medical imaging.

Scientists unlock effect of psychedelic drug DMT on the human brain

The powerful psychedelic can give you a near-death experience. Here is how it affects your brain on the inside.

Dimethyltryptamine, or DMT, is a powerful psychedelic whose effect on the human brain lasts for only some minutes, but in that short span of time, the user experiences some high-level mental changes.

The researchers examined the brain activity of the participants before, during, and after the DMT test. Here is what they found.

For the first time, a team of researchers from the Imperial College of London has monitored these changes in detail. They administered a high dose of DMT to 20 healthy individuals who voluntarily participated in their study.

NASA and Other Agencies Have a New Pollution Eye in the Sky

TEMPO will study pollutants like asthma-inducing nitrogen dioxide and cancer-causing formaldehyde.

A new space instrument called TEMPO will target North America’s air pollution problem, and highlights one of its big challenges.

The Tropospheric Emissions: Monitoring Pollution instrument, or TEMPO, will gather pollution data across North America. On Tuesday, representatives from NASA and the Smithsonian Astrophysical Observatory (part of the Center for Astrophysics | Harvard and Smithsonian in Cambridge, Massachusetts) spoke about the soon-to-launch project, in an event held at the Smithsonian National Air and Space Museum in Washington, D.C.

Atmospheric physicists and NASA officials on Tuesday called this a major step forward in pollution monitoring. TEMPO will let scientists see emissions as they occur throughout the day, hour by hour, instead of a single sampling. The project involves members from the National Oceanic and Atmospheric Administration (NOAA) and the Environmental Protection Agency (EPA).

AI Develops Cancer Drug in 30 Days, Predicts Life Expectancy with 80% Accuracy

AI technologies invented by scientists at the University of British Columbia and B.C. Cancer has succeeded in discovering a previously-unknown treatment pathway for an aggressive form of liver cancer, designing a new drug to treat it in the process.

The team also deployed AI to determine a patient’s life expectancy, by having it analyze doctors’ notes. The AI reportedly has an 80 percent accuracy rate in its predictions.

The medical advances came about thanks to AlphaFold, a protein structure database featuring AI analysis that can design potential medicines. The team’s work focused on hepatocellular carcinoma (HCC), which is a common and aggressive form of liver cancer.

Biologists Figured Out How to Generate New Neurons in the Adult Brain, Revolutionizing Neurodegenerative Disease Research

Recently biologists discovered how to generate new neurons in the adult brain. This is an incredible breakthrough that has enormous potential to revolutionize neurodegenerative disease research. By generating genetically-mutated mice with a unique gene that activates dormant neural stem cells, scientists were able to generate new neurons in the brain. For years, scientists have been searching for ways to promote the growth of new neurons in the brain, especially in individuals with neurodegenerative diseases such as Alzheimer’s and Parkinson’s. This new discovery could lead to new treatments and therapies that could help to restore brain function and improve the quality of life for millions of people around the world.

Leslie Samuel, founder of Interactive Biology, gives some context for the importance of genetic trading between organisms for scientific research, and notes how the loss of nerve cells in the brain is one of the hallmarks of neurodegenerative diseases. The ability to generate new neurons in the adult brain could be a game-changer in the field of neurology.

Nvidia GTC Highlights The Physical Side Of AI

ChatGPT launched a tide wave of interest in AI. For many consumers, AI is finally living up to long overdue expectations. The accomplishments of ChatGPT in a short period of time are phenomenal. But what is yet to come when AI is combined with robotics will change everything.

I have been promoting the advances in robotics for several years. I even called 2022 the year of robotics, partially because of the growing need to overcome shortages in labor and to handle tasks beyond the physical or mental capability of humans, and partially because of the continued advances that AI, accelerated processing, semiconductor, sensors, wireless connectivity, and software technologies are enabling to develop advanced, autonomous machines. Robots are no longer just for the manufacturing floor. They are hazardous material handlers, janitors, personal assistants, food preparers, food deliverers, security guards, and even surgeons that are increasingly autonomous. Essentially, they are AI in the physical world. As a result, robot competitions are heating up from middle schools to Las Vegas.

As seen at CES, robotics technology is advancing rapidly with advances in technology. My favorite examples were the multi-configurable Yarbo outdoor robot and the John Deere See & Spray. Yarbo can be a mower, a leaf blower, or a snow blower. If it could dispose of animal excrement and the annoying neighbor, it would be perfect yard tool. On the other end of the spectrum was the John Deere See & Spray Ultimate, a tractor with up to a 120-foot (36.6m) reach that uses AI/ML to detect weeds smaller than the size of a smart phone camera and spray herbicide accordingly. John Deere also offers self-drive tractors.

Rep. Bilirakis on the Longevity Science Caucus

Color me surprised… a new bipartisan house caucus on longevity.

We in the longevity field have received powerful allies on Capitol Hill with the creation of the bipartisan Congressional Caucus for Longevity Science. We had the opportunity to ask questions of one of its co-chairs.

The fight against aging must become one of humanity’s main priorities if we want to see meaningful progress on a global scale. This requires recruiting allies among politicians and other decision makers.

Recently, a major step in that direction was made. Reps. Gus Bilirakis (R-FL) and Paul Tonko (D-NY) announced the formation of the Congressional Caucus for Longevity Science. According to the press release, the caucus “aims to educate Members about the growing field of aging and longevity biotechnology, and promote initiatives aimed at increasing the healthy average lifespan of all Americans.”
