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.

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 energy levels, leading to superior accuracy in healthcare and manufacturing applications such as medical imaging 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.
OpenAI has sparked an explosion of funding and software development around artificial-intelligence software that understands human language. While the technology still makes plenty of mistakes, new applications are coming out in droves, from tools that help marketers write copy to audio chatbots that may be able to negotiate discounts for customers of a companies like Comcast.
Last week, subscribers of The Information joined a conference call about the year ahead in AI with Noam Shazeer, CEO of Character, which is developing chatbots similar to OpenAI’s ChatGPT and who co-authored a seminal research paper on that subject while working at Google; and Clement Delangue, CEO of Hugging Face, which runs a Github-like service for software engineers to store their machine learning models.
A ‘longevity protein’ discovered in the DNA of centenarians promises to rejuvenate the heart by at least 10 years. Hope comes from a preclinical study coordinated by Annibale Puca of the MultiMedica group in Milan and Paolo Madeddu of the University of Bristol in the United Kingdom, funded by the British Heart Foundation and the Italian Ministry of Health and published in ‘Cardiovascular Research’, a journal of the European Society of Cardiology (ESC).
Altering a cellular process can lead stem cells—cells from which other cells in the body develop—to die or regenerate, according to a new study led by Cedars-Sinai and the University of California, San Francisco (UCSF).
The findings, to be published today (January 13) in the peer-reviewed journal Cell Stem Cell, may assist in the development of new drugs that can manipulate this process to slow or stop cancer from growing and spreading, and enable regeneration in the context of other diseases.
Ophir Klein, MD, PhD, executive director of Cedars-Sinai Guerin Children’s and the senior author of the study, said the findings underscore the body’s need to produce just the right amount of new cells.

Many of us have seen microscopic images of neurons in the brain — each neuron appearing as a glowing cell in a vast sea of blackness. This image is misleading: Neurons don’t exist in isolation. In the human brain, some 86 billion neurons form 100 trillion connections to each other — numbers that, ironically, are far too large for the human brain to fathom.
Wei-Chung Allen Lee, Harvard Medical School associate professor of neurology at Boston Children’s Hospital, is working in a new field of neuroscience called connectomics, which aims to comprehensively map connections between neurons in the brain.
