This is the article - about a possible connection between black holes and dark energy. There now seems to be evidence for this from both DESI and earlier observations I was involved with 🧪🔭 www.scientificamerican.com/article/is-d...

Are Black Holes Creating Dark Energy?

A controversial prediction about black holes and the expansion force of the universe could explain a cosmology mystery

🧫 AI discovers new narrow-spectrum antibiotic

Researchers used deep learning to identify enterololin, a compound that targets harmful Enterobacteriaceae while sparing healthy gut microbes. A step toward safer antibiotics.

Discovery and artificial intelligence-guided mechanistic elucidation of a narrow-spectrum antibiotic - Nature Microbiology

Enterololin is a narrow-spectrum antibiotic that selectively kills Enterobacteriaceae in vitro and in a mouse model of adherent-invasive Escherichia coli gut infection. AI-guided mechanism-of-action studies identified LolCDE as its molecular target.

After years of complaining about cancel culture, the current administration has taken it to a new and dangerous level by routinely threatening regulatory action against media companies unless they muzzle or fire reporters and commentators it doesn’t like.

One of the biggest frustrations I have is the lack of transparency around AI's energy use and environmental impacts. I know the numbers are out there... but somehow we're not seeing them 🫠

Thank you @wired.com for covering this topic in such depth and detail !

How Much Energy Does AI Use? The People Who Know Aren’t Saying

A growing body of research attempts to put a number on energy use and AI—even as the companies behind the most popular models keep their carbon emissions a secret.

Lolz. Amusing listening to Ali Ghodsi (Databricks) crowing about his/ their masterful stroke of genius in renaming machine learning to AI...😂 Maybe in the very narrowest of contexts

I think that's doing those people a disservice, not least because of the choice of analogy (I get what you're saying, but I think it's the wrong analogy). Intelligence is also poorly defined, so we would need an agreed definition to work with. There's no doubt GenAI has advanced incredibly quickly.

A digital illustration shows a stepped pyramid, resembling El Castillo at Chichen Itza, centered within a white hexagonal outline. The pyramid is made of golden-orange blocks, with a wide, straight staircase leading up its front. Behind the pyramid, teal mountains rise under a light blue sky with a white cloud. A bright yellow sun is visible in the upper right. The entire hexagonal illustration is set against a dark reddish-brown background with a faint pattern of small, lighter red squares and circles along the top and bottom edges.
