Brain Cell Transplant Is an Experimental Procedure

Brain transplant is not a reality for humans or for any living organism. But there are human research experiments in which transplanted brain cells are used to help treat several diseases that affect the brain. So far, there are very few results and measured outcomes of brain cell transplant, but the concept of transplanting brain tissue has shown some promise in preliminary studies.

If you are interested in having a brain cell transplant procedure, you can talk to your healthcare provider and look for a university or research center where brain cell transplant procedures are being done. These procedures tend to be part of research studies, so you will likely need to enroll in a research study if you want to have this type of treatment.

The brain is composed of many different regions and cells. Neurons in the brain have dedicated functions, and they do not typically heal when they are damaged. Parkinson’s disease, stroke, multiple sclerosis (MS), epilepsy, Alzheimer’s disease, and head trauma are among the conditions for which brain cell transplant has been used for humans in an experimental setting.

A bend in universe: Researchers may have discovered the cosmic string proof

A recent analysis of a peculiar pair of galaxies located billions of light-years away suggests the possibility of a cosmic string —a hypothetical feature in the fabric of the Universe. Initially considered distinct, the two galaxies may be duplicated images caused by gravitational lensing, a phenomenon where space-time bends around foreground mass, acting like a lens.

Led by researchers of the Indian Institute of Astrophysics, the study identifies a cosmic string candidate, CSc-1, in the cosmic microwave background, the lingering radiation from the Universe’s birth. Cosmic strings, theoretical one-dimensional wrinkles formed at the dawn of time, are believed to be highly dense and massive, potentially extending across the entire Universe.

Observationally proving cosmic strings is challenging because their effects can resemble other phenomena. However, minute differences in their impact distinguish them. The researchers focused on a galaxy pair, SDSSJ110429, within CSc-1 as a potential cosmic string signature. Gravitational lensing typically involves a foreground mass causing observable distortions, but SDSSJ110429 lacks evident foreground mass or distorted light.

China’s Cyber Threat: Is U.S. Infrastructure at Risk?

The Chinese military has been escalating its cyber capabilities, posing a potential threat to key American infrastructure. This includes power and water utilities, as well as communication and transportation systems. Over the past year, hackers affiliated with China’s People’s Liberation Army have successfully infiltrated the computer systems of approximately two dozen critical entities.

These cyber intrusions are not isolated incidents. They are part of a broader strategy to develop methods that could cause panic, chaos, or disrupt logistics in the event of a U.S.-China conflict. The victims of these cyber-attacks include a water utility in Hawaii, a major West Coast port, and at least one oil and gas pipeline. There was also an attempt to breach the operator of Texas’s power grid.

China’s Military Linked to Cyber Infiltration of US Essential Services: Report

Takeaways:

• The Chinese military is reportedly increasing its attempts to infiltrate essential infrastructure, utilities, communication, and transportation services in the U.S., according to anonymous U.S. officials and cybersecurity experts.

• Hackers linked with China’s People’s Liberation Army have infiltrated around two dozen essential service entities in the past year, including a water utility in Hawaii, an oil and gas pipeline, and a West Coast port.

AI scientists make ‘exciting’ discovery using chatbots to solve maths problems

Artificial intelligence researchers claim to have made the world’s first scientific discovery using a large language model, a breakthrough that suggests the technology behind ChatGPT and similar programs can generate information that goes beyond human knowledge.

The finding emerged from Google DeepMind, where scientists are investigating whether large language models, which underpin modern chatbots such as OpenAI’s ChatGPT and Google’s Bard, can do more than repackage information learned in training and come up with new insights.

“When we started the project there was no indication that it would produce something that’s genuinely new,” said Pushmeet Kohli, the head of AI for science at DeepMind. “As far as we know, this is the first time that a genuine, new scientific discovery has been made by a large language model.”

The future of intelligence: artificial, natural, and combined

Twenty-four years ago, Ray Kurzweil predicted computers would reach human-level intelligence by 2029. This was met with great concern and criticism. In the past six months technology experts have come around to agree with him. According to Kurzweil, over the next two decades, AI is going to change what it means to be human. We are going to invent new means of expression that will soar past human language, art, and science of today. All of the concepts that we rely on to give meaning to our lives, including death itself, will be transformed.\

Examining Hemp-Derived Cannabinoids: A Recent Study on Usage and Awareness

A recent study published in JAMA Network Open investigates the level of usage of hemp-derived cannabinoids, including cannabinol (CBN), cannabigerol (CBG), Delta 8-THC, and cannabidiol (CBD). The reason hemp-derived cannabinoids were chosen for the study was due to passage of the 2018 Farm Bill, which removed hemp from the definition of marijuana previously outlined in the Controlled Substances Act (CSA). However, THC is still classified as a Schedule I drug, meaning it’s still illegal under federal law, and despite the “de-scheduling” of hemp, there is presently no data regarding the estimated usage of hemp-derived cannabinoids.

“While the de-scheduling of hemp products initially opened up the market for CBD products, it also applies to the 100-plus cannabinoids also found in the plant,” said Dr. Kevin Boehnke, who is a Research Assistant Professor in the Department of Anesthesiology and the Chronic Pain and Fatigue Research Center at the University of Michigan, and a co-author on the study. “That means, as with CBD, all of them can follow that same path and be sold in gas stations, as ingredients in cosmetics, as well as in dispensaries—there will likely be substantial proliferation of some of these compounds.”

For the study, the researchers conducted a cross-sectional survey study of individuals aged 18 and up inquiring about past-year use of hemp-derived cannabinoids. Of the 6,666 participants who received the survey, only 1,169 completed it. Of those 1,169 participants, the researchers found that 71.7 percent had heard of CBD compared to 41.2 percent, 18.4 percent, and 16.8 percent for Delta 8-THC, CBG, and CBN, respectively. Additionally, 21.2 percent of the participants reported using CBD within the past year compared to 11.9 percent, 5.2 percent, and 4.4 percent for Delta 8-THC, CBG, and CBN, respectively, with 25.5 percent of participants reporting using some type of emerging cannabinoid within the last year, as well.
