A particular ‘sandwich’ of graphene and boron nitride may lead to next-gen microelectronics

Posted by in categories: computing, transportation

Moiré patterns occur everywhere. They are created by layering two similar but not identical geometric designs. A common example is the pattern that sometimes emerges when viewing a chain-link fence through a second chain-link fence.

For more than 10 years, scientists have been experimenting with the moiré pattern that emerges when a sheet of graphene is placed between two sheets of . The resulting moiré pattern has shown tantalizing effects that could vastly improve that are used to power everything from computers to cars.

A new study led by University at Buffalo researchers, and published in Nature Communications, demonstrated that graphene can live up to its promise in this context.

Advance in Intelligent Neuroprosthetics May Benefit Those With Motor Diseases

Posted by in categories: biotech/medical, cyborgs, robotics/AI

Summary: It may be possible to optimize the stimulation parameters of brain implants in animals without human intervention. The study highlights the potential for autonomous optimization of prostheses implanted in the brain. The advance may prove to be beneficial for those with spinal cord injury and diseases that affect movement.

Source: University of Montreal.

Scientists have long studied neurostimulation to treat paralysis and sensory deficits caused by strokes and spinal cord injuries, which in Canada affect some 380,000 people across the country.

Why the technological singularity could happen in the next 7 years (as of 2023)

Posted by in categories: robotics/AI, singularity

There are a lot of reasons why we think technological singularity will happen sooner than 2045. With technology advancing at a rapid pace, an abundance of data, increased investment, collaboration, and potential breakthroughs, we might just wake up one day and realize that the robots have taken over. But hey, at least they’ll do our laundry.

Do you think singularity will happen sooner than 2045? Why or why not? Answer in the comment section below.

Hematopoietic Transfer of the Anti-Cancer and Lifespan-Extending Capabilities of A Genetically Engineered Blood System

Posted by in categories: bioengineering, biotech/medical, genetics, life extension

A causal relationship exists among the aging process, organ decay and dis-function, and the occurrence of various diseases including cancer. A genetically engineered mouse model, termed EklfK74R/K74R or Eklf (K74R), carrying mutation on the well-conserved sumoylation site of the hematopoietic transcription factor KLF1/ EKLF has been generated that possesses extended lifespan and healthy characteristics including cancer resistance. We show that the high anti-cancer capability of the Eklf (K74R) mice are gender-, age-and genetic background-independent. Significantly, the anti-cancer capability and extended lifespan characteristics of Eklf (K74R) mice could be transferred to wild-type mice via transplantation of their bone marrow mononuclear cells. Targeted/global gene expression profiling analysis has identified changes of the expression of specific proteins and cellular pathways in the leukocytes of the Eklf (K74R) that are in the directions of anti-cancer and/or anti-aging. This study demonstrates the feasibility of developing a novel hematopoietic/ blood system for long-term anti-cancer and, potentially, for anti-aging.

The authors have declared no competing interest.

A test told me my brain and liver are older than they should be. Should I be worried?

Is Reality an Illusion? — Professor Donald Hoffman, PhD

Posted by in categories: computing, cosmology, neuroscience

Get early access to our latest psychology lectures: http://bit.ly/new-talks5

If I have a visual experience that I describe as a red tomato a meter away, then I am inclined to believe that there is, in fact, a red tomato a meter away, even if I close my eyes. I believe that my perceptions are, in the normal case, veridical—that they accurately depict aspects of the real world. But is my belief supported by our best science? In particular: Does evolution by natural selection favor veridical perceptions? Many scientists and philosophers claim that it does. But this claim, though plausible, has not been properly tested. In this talk, I present a new theorem: Veridical perceptions are never more fit than non-veridical perceptions which are simply tuned to the relevant fitness functions. This entails that perception is not a window on reality; it is more like a desktop interface on your laptop. I discuss this interface theory of perception and its implications for one of the most puzzling unsolved problems in science: the relationship between brain activity and conscious experiences.

Just Running ChatGPT Is Costing OpenAI a Staggering Sum Every Single Day

Posted by in category: robotics/AI

ChatGPT’s immense popularity and power make it eye-wateringly expensive to maintain, The Information reports, with OpenAI paying up to $700,000 a day to keep its beefy infrastructure running, based on figures from the research firm SemiAnalysis.

“Most of this cost is based around the expensive servers they require,” Dylan Patel, chief analyst at the firm, told the publication.

The costs could be even higher now, Patel told Insider in a follow-up interview, because these estimates were based on GPT-3, the previous model that powers the older and now free version of ChatGPT.
