The wetware in a casket of bone that we each carry on our shoulders is 1 million times more efficient than the AI models run by services like ChatGPT, Stable Diffusion, or DALL-E.

In this TechFirst with John Koetsier we chat for a second time with Gordon Wilson, CEO of Rain AI, which is building a neuromorphic artificial brain simulating the structure of our biological brains, and aiming at 10,000 to 100,000 greater energy efficiency than current AI architectures.

We also discuss “mortal computation” and a radical co-design of the hardware and software for AI systems, which could lead to much more efficient (and more effective) smart tools, machines, and companions.

Summary: Researchers have developed a new family of nano-scale capsules capable of carrying CRISPR gene editing tools to different organs of the body before harmlessly dissolving. The capsules were able to enter the brains of mice and successfully edit a gene associated with Alzheimer’s disease.

Gene therapies have the potential to treat neurological disorders like Alzheimer’s and Parkinson’s diseases, but they face a common barrier — the blood-brain barrier.

Dual-action cell therapy engineered to eliminate established tumors and train the immune system to eradicate primary tumor and prevent cancer’s recurrence. Scientists are harnessing a new way to turn cancer cells into potent, anti-cancer agents. In the latest work from the lab of Khalid Shah, MS, PhD, at Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, investigators have developed a new cell therapy approach to eliminate established tumors and induce long-term immunity, training the immune system so that it can prevent cancer from recurring. The team tested their dual-action, cancer-killing vaccine in an advanced mouse model of the deadly brain cancer glioblastoma, with promising results. Findings are published in Science Translational Medicine.

Jan. 20 (UPI) — Two astronauts embarked on the first spacewalk of 2023 on Friday as they work toward upgrading the International Space Station’s power generation system.

NASA astronaut Nicole Mann teamed up with Koichi Wakata of the Japan Aerospace Exploration Agency for the morning spacewalk, expected to last about 6 1/2 hours. They will install a modification kit at the far end of the ISS, allowing for the future installation of the roll-out solar array.

The spacewalk was scheduled to start at 8:15 a.m., EST, but NASA officials said the operation was ahead of schedule with both astronauts setting their spacesuits to battery power about a minute earlier, marking the official start of the mission.

JERUSALEM, Jan 19 (Reuters) — Israel’s chief rabbi has given a kosher stamp of approval this week to a company looking to sell steak grown from cow cells — while effectively taking the animal itself out of the equation.

Cultivated meat, grown from animal cells in a lab or manufacturing plant, has been getting a lot of attention as a way to sidestep the environmental toll of the meat industry and address concerns over animal welfare.

This method, however, has raised questions over religious restrictions, like kashrut in Judaism or Islam’s halal.

For the first time since it was proposed more than 80 years ago, scientists from Nanyang Technological University, Singapore (NTU Singapore) have demonstrated the phenomenon of “quantum recoil,” which describes how the particle nature of light has a major impact on electrons moving through materials. The research is published online today (January 19) in the journal Nature Photonics.

Making quantum recoil a practical reality should eventually allow businesses to more accurately produce X-rays of specific levels, leading to superior accuracy in healthcare and manufacturing applications such as and flaw detection in semiconductor chips.

Quantum recoil was theorized by Russian physicist and Nobel laureate Vitaly Ginzburg in 1940 to accurately account for radiation emitted when charged particles like electrons move through a medium, such as water, or materials with repeated patterns on the surface, including those on butterfly wings and graphite.
