String theory provides a new take on the expansion of the Universe

String theory could reshape our understanding of the Universe’s accelerating expansion and unlock the mysteries of dark energy.

The accelerating expansion of the Universe might not be just an unexplained phenomenon — according to a new proposal by theoretical physicists, it could be a fundamental feature woven into the very fabric of reality.

The researchers suggest that space is not an empty vacuum but that instead our whole Universe is a complex quantum object called the Glauber-Sudarshan state, where countless interacting strings are constantly born and disappear. This hypothesis breathes new life into string theory, which has long aimed to unify all the fundamental forces of nature.

Exosomes Break Rat Lifespan Record

This has to do with E5, but last I checked they were only doing skin rejuvenation treatments in people.

In Aging Cell, researchers have published their findings that exosomes, which we have previously reported to extend the lives of mice, also extend the lives of rats.

Known to be effective

Exosomes, a subset of extracellular vesicles (EVs), can be visualized as messages and packages that cells send to one another. Along with lifespan studies, EVs have been investigated for their ability to treat liver fibrosis, and they have been identified as potential biomarkers of disease [1].

Sam Altman and OpenAI executives outline future plans in Reddit AMA

OpenAI’s senior leaders recently participated in a Reddit AMA session, revealing their future plans and other insights. The session featured Sam Altman (CEO), Kevin Weil (Chief Product Officer), Mark Chen (SVP of Research), Srinivas Narayanan (VP of Engineering), and Jakub Pachocki (Chief Scientist).

Model Development & Releases:

Q: Is there a plan to continue to release models in the “o” series from now on? Will you continue to improve on the “regular” models (e.g., GPT-3, 4, 4o, 5)? Both, or a combination of those?

Watch Live: SpaceX Dragon’s High-Stakes Docking Dance on the International Space Station

To prepare for NASAs 31st SpaceX commercial resupply mission, four crew members aboard the International Space Station (ISS) will relocate the SpaceX Crew-9 Dragon spacecraft to a new docking port on Sunday, November 3.

Live coverage will begin at 6:15 a.m. EST on NASA+ and continue through docking completion. NASA content can also be accessed through various platforms, including social media.

At 6:35 a.m., NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, along with Roscosmos cosmonaut Aleksandr Gorbunov, will undock the spacecraft from the forward-facing port of the ISS Harmony module. By 7:18 a.m., they plan to redock it at the module’s space-facing port.

Non-lithium alternatives: Reliance completes sodium-ion acquisition, Amazon tries ‘membrane-free’ flow battery

India’s Reliance Industries has completed the takeover of sodium-ion battery company Faradion, while Amazon is set to trial a novel flow battery technology.

Lithium-ion (Li-ion) presently dominates the global energy storage and electric vehicle (EV) sectors as the battery chemistry of choice.

Scientists successfully reverse liver fibrosis in mice

Cirrhosis, hepatitis infection and other causes can trigger liver fibrosis—a potentially lethal stiffening of tissue that, once begun, is irreversible. For many patients, a liver transplant is their only hope. However, research at Cedars-Sinai in Los Angeles may offer patients a glimmer of hope. Scientists there say they’ve successfully reversed liver fibrosis in mice.

Reporting in the journal Nature Communications, the team say they’ve discovered a genetic pathway that, if blocked, might bring fibrosis to a halt.

The three genes involved in this fibrotic process are called FOXM1, MAT2A and MAT2B.
