In an all-hands video conference call to Cruise staff on Monday afternoon, General Motors CEO Mary Barra attempted to re-energize the staff of Cruise, GM’s on-edge autonomous vehicle subsidiary, after its CEO and chief product officers both resigned following several weeks of enormous setbacks for the company.
As OpenAI employees threaten a mass exodus in the wake of CEO Sam Altman’s ouster by the board of directors, some OpenAI customers are beginning to look for the exits.
Startups built on OpenAI’s technology are looking for new options after the boardroom coup that ousted CEO Sam Altman.
In a surprising turn of events, OpenAI’s board abruptly fired co-founder and CEO Sam Altman on Friday.
The chaos at OpenAI in response to CEO Sam Altman’s firing reveals the problematic influence of the Effective Altruism movement.
The original definition of the chosen word is to “seem to see, hear, feel, or smell” something that does not exist, usually because of “a health condition or because you have taken a drug”
The psychological verb gained an extra meaning in 2023 that ‘gets to the heart of why people are talking about artificial intelligence’
Sam Altman and the OpenAI board are now in talks for his possible return, specifically he’s speaking with Adam d’Angelo.
Sam Altman and members of the OpenAI board have opened negotiations aimed at a possible return of the ousted co-founder and chief executive officer to the artificial intelligence company, according to people with knowledge of the matter.
Discussions are happening between Altman and at least one board member, Adam D’Angelo, said the people, who asked not to be identified because the deliberations are private and they may not come to fruition. The talks also involve some of OpenAI’s investors, many of whom are pushing for his reinstatement, one of the people said.

Ford said Tuesday it is cutting production capacity by roughly 43% to 20 gigawatt hours per year and reducing expected employment from 2,500 jobs to 1,700 jobs. The company declined to disclose how much less it would invest in the plant. Based on the reduced capacity, it would still be about a $2 billion investment.
The decision adds to a recent retreat from EVs by automakers globally. Demand for the vehicles is lower than expected due to higher costs and challenges with supply chains and battery technologies, among other issues.
Reductions at the Marshall, Michigan, plant are part of Ford’s plans announced last month to cut or delay about $12 billion in previously announced EV investments. The company will also postpone construction of another electric vehicle battery plant in Kentucky.
A team of researchers at DeepMind focusing on the next frontier of artificial intelligence—Artificial General Intelligence (AGI)—realized they needed to resolve one key issue first. What exactly, they asked, is AGI?
It is often viewed in general as a type of artificial intelligence that possesses the ability to understand, learn and apply knowledge across a broad range of tasks, operating like the human brain. Wikipedia broadens the scope by suggesting AGI is “a hypothetical type of intelligent agent [that] could learn to accomplish any intellectual task that human beings or animals can perform.”
OpenAI’s charter describes AGI as a set of “highly autonomous systems that outperform humans at most economically valuable work.”
Protein indicators of subclinical peripheral heath in plasma were linked with markers of Alzheimer’s disease and neurodegeneration, cross-sectional proteomic analyses showed.
Greater protein-based risk for cardiovascular disease, heart failure mortality, and kidney disease was associated with plasma biomarkers of amyloid-beta, phosphorylated tau181 (p-tau181), neurofilament light (NfL, a measure of neuronal injury), and glial fibrillary acidic protein (GFAP, a measure of astrogliosis), even in people without cardiovascular or kidney disease, reported Keenan Walker, PhD, of the National Institute on Aging in Baltimore, and co-authors.
Proteomic indicators of body fat percentage, lean body mass, and visceral fat also were tied to p-tau181, NfL, and GFAP, Walker and colleagues wrote in the Annals of Neurology.
The sleep-wake cycle is among the most well-known circadian rhythms in the body and is severely affected in Alzheimer’s disease (AD). “Eighty percent of patients with AD suffer dysregulation or disruption of circadian rhythms, and the obvious clinical manifestations are the sleep-wake reversals,” Desplats said. “These patients are very sleepy during the day, agitated during the night, more confused, and sometimes aggressive.”
The feeding-fasting cycle is one of the strongest signals you can send the body to entrain the circadian clock.-Paula Desplats, University of California, San Diego
In a recent study published in Cell Metabolism, Desplats’s team used mice that are genetically engineered to develop AD to test whether intermittent fasting improves circadian rhythm abnormalities.3 Rather than restricting calories or making dietary changes, they simply limited food access to a defined six-hour daily window. They found that time-restricted eating improved sleep, metabolism, memory, and cognition, and reduced brain amyloid deposits and neuroinflammatory gene expression. “Many of the genes that are affected in AD are rhythmically expressed in the brain, meaning that they are in direct relation with the circadian clock and are involved in functions that are fundamental to AD pathology,” Desplats said. Intermittent fasting restored the rhythmic activity of these genes, but the real surprise was the extent to which it mitigated brain amyloid deposits and improved cognition and sleep-wake behaviors. “I didn’t expect that it will have such a dramatic impact on pathology,” Desplats said.
Observations from the Event Horizon Telescope show that the supermassive black hole at the heart of the galaxy M87 has twisted magnetic fields that help matter and light escape from the immense gravit.
