“Wish I had this to cite,” lamented Jacob Andreas, a professor at MIT, who had just published a paper exploring the extent to which language models mirror the internal motivations of human communicators.

Jan Leike, the head of alignment at OpenAI, who is chiefly responsible for guiding new models like GPT-4 to help, rather than harm, human progress, responded to the paper by offering Burns a job, which Burns initially declined, before a personal appeal from Sam Altman, the cofounder and CEO of OpenAI, changed his mind.

“Collin’s work on ‘Discovering Latent Knowledge in Language Models Without Supervision’ is a novel approach to determining what language models truly believe about the world,” Leike says. “What’s exciting about his work is that it can work in situations where humans don’t actually know what’s true themselves, so it could apply to systems that are smarter than humans.”

SAN FRANCISCO/WASHINGTON, Oct 5 (Reuters) — OpenAI, the company behind ChatGPT, is exploring making its own artificial intelligence chips and has gone as far as evaluating a potential acquisition target, according to people familiar with the company’s plans.

The company has not yet decided to move ahead, according to recent internal discussions described to Reuters. However, since at least last year it discussed various options to solve the shortage of expensive AI chips that OpenAI relies on, according to people familiar with the matter.

These options have included building its own AI chip, working more closely with other chipmakers including Nvidia and also diversifying its suppliers beyond Nvidia (NVDA.O).

LOS ANGELES — Northrop Grumman will drop plans to develop its own commercial space station and instead assist a competing effort led by Voyager Space, the companies announced Oct. 4.

Under the new partnership, the companies will cooperate on the development of fully autonomous docking systems for Northrop’s Cygnus cargo spacecraft, allowing it to dock with Voyager’s Starlab space station. The companies also said they will “further explore opportunities to strengthen the development of Starlab” that could include Northrop providing engineering design services for that station. Ars Technica first reported about a potential partnership between the companies.

“This collaboration is a major step forward for the Starlab program,” said Dylan Taylor, chairman and chief executive of Voyager Space, in a statement. “Northrop Grumman’s technical capability and proven success in cargo resupply services will play a pivotal role as we accelerate Starlab’s development.”

NGC 4,654 is a spiral galaxy with some interesting nuances of stellar formation.

Have you seen an unusually bright object moving through the evening sky recently?

Chances are that it wasn’t one of the mysterious objects that the DoD and NASA are currently studying, but was instead one of the growing number of manmade spacecraft taking up residence in Earth’s orbit.

And this one has astronomers particularly concerned.

A team of astrophysicists says they may have found evidence for “cosmic strings”, long-hypothesized defects in the universe left over from its early in its expansion.

Cosmic strings were first suggested in the 1970s by theoretical physicist Tom W. B. Kibble, and later revived in the context of string theory. The one-dimensional strings, far narrower even than a proton, are thought to have sprung into existence in the very first second of the universe and could potentially stretch right across it.

The strings, sometimes referred to as cracks in the universe, had not been detected since they were conceived, though there were a few ideas on how we might. When strings cross, for instance, it could provide us an opportunity to find them.

A process of surgically joining the circulatory systems of a young and old mouse has been found to slow aging at a cellular level and extend the older animal’s life by as much as 10%.

Recently published in Nature Aging, a study led by researchers from Duke Health discovered the longer the animals shared circulation, the longer the anti-aging benefits lasted once the two were no longer connected.

The findings suggest that the young benefit from a cocktail of components and chemicals in their blood that contribute to vitality, and these factors could potentially be isolated as therapies to speed healing, rejuvenate the body, and add years to an older individual’s life.

A recent study reports something strange: When mice with Alzheimer’s disease inhale menthol, their cognitive abilities improve. It seems the chemical compound can stop some of the damage done to the brain that’s usually associated with the disease.

In particular, researchers noticed a reduction in the interleukin-1-beta (IL-1β) protein, which helps to regulate the body’s inflammatory response – a response that can offer natural protection but one that leads to harm when it’s not controlled properly.

The team behind the study, which was published in April 2023, says it shows the potential for particular smells to be used as therapies for Alzheimer’s. If we can figure out which odors cause which brain and immune system responses, we can harness them to improve health.

This isn’t a new discovery but something we’ll have to deal with in some places. I’ve actually drank noxious tap water and got really sick.

Most Americans take it for granted that the water that comes out of their taps is clean and safe to drink.

But a new study published by a University of New Mexico scientist with colleagues from across the U.S. warns that water from many wells and community water systems contains unsafe levels of toxic contaminants, exposing millions to health risks, including cancer.
