OpenAI recently topped $1.6 billion in annualized revenue on strong growth from its ChatGPT product, up from $1.3 billion as of mid-October, according to two people with knowledge of the figure.

The 20% growth over two months represented in that figure—a measure of the prior month’s revenue multiplied by 12—suggests that the company was able to hold onto its business momentum in selling artificial intelligence to enterprises despite a leadership crisis in November that provided an opening for rivals to go after its customers.

Innovative quantum-inspired imaging technique excels in low-light conditions, offering new prospects in medical imaging and art conservation.

Researchers at the University of Warsaw’s Faculty of Physics with colleagues from Stanford University and Oklahoma State University have introduced a quantum-inspired phase imaging method based on light intensity correlation measurements that is robust to phase noise. The new imaging method can operate even with extremely dim illumination and can prove useful in emerging applications such as in infrared and X-ray interferometric imaging and quantum and matter-wave interferometry.

NEW DELHI: The “Devil Comet,” officially known as 12P, is currently making its way towards Earth and is anticipated to undergo a significant eruption soon. This comet, which is nearly three times the size of Mount Everest, is classified as a cryovolcano, which means it erupts due to the build-up and ignition of gas and ice, much like a frozen soda can exploding. The comet is notably large, with a diameter of 18.6 miles, comparable to the size of a small city.

According to Astronomy.com, it’s a short-period comet, completing an orbit around the Sun approximately every 71.2 years, a pattern similar to the well-known Halley’s Comets like this, with an orbital period of less than 200 years, are categorized as short-period comets.

Comet 12P/Pons-Brooks is not a recent discovery in our solar system. Its existence has been acknowledged since 1,812, when it was first observed by the comet hunter Jean-Louis Pons, who noted it at a 4th magnitude brightness. However, the initial observations were not detailed enough to accurately forecast its future appearances. Consequently, it was “rediscovered” in 1,883 by William Brooks. Contemporary astronomers, analyzing historical records, suggest that this comet might have been documented in earlier passes, possibly as far back as 1,385, the Astronomy.com report said.

Early PDP-11 models were not overly impressive. The first PDP-11 11/20 cost $20,000, but it shipped with only about 4KB of RAM. It used paper tape as storage and had an ASR-33 teletype printer console that printed 10 characters per second. But it also had an amazing orthogonal 16-bit architecture, eight registers, 65KB of address space, a 1.25 MHz cycle time, and a flexible UNIBUS hardware bus that would support future hardware peripherals. This was a winning combination for its creator, Digital Equipment Corporation.

The initial application for the PDP-11 included real-time hardware control, factory automation, and data processing. As the PDP-11 gained a reputation for flexibility, programmability, and affordability, it saw use in traffic light control systems, the Nike missile defense system, air traffic control, nuclear power plants, Navy pilot training systems, and telecommunications. It also pioneered the word processing and data processing that we now take for granted.

And the PDP-11’s influence is most strikingly evident in the device’s assembly programming.

I’m thinking my autistic sister has this. Maybe my 80 year old mother too. Short but informative article.

Neuroinflammation—as measured by levels of activated microglia, the brain’s immune cells—was strongly linked with irritability, agitation, and nighttime disturbances in people with dementia, recent research found. The results, published in JAMA Network Open, were based on data from a cross-sectional study that involved 109 participants aged 38 to 87 years, about two-thirds of whom did not have cognitive impairment.

Higher levels of microglial activation, and particularly microglial activation–associated irritability, in participants with dementia were also tied to greater distress in their caregivers, family members, or close friends.
