How Black Holes Help Stars Form In the Phoenix galaxy cluster, the presence of a black hole allows gas to cool, collapse, and form stars at an extremely high rate, in contrast with other clusters where the black hole heats the gas a...

The plasma that fills intergalactic space in galaxy clusters radiates so much in the x-ray band that it loses energy and slumps toward the cluster center. Such "cooling flows" are arrested by black hole jets but not in the Phoenix Cluster, new JWST observations reveal.

NOAA Employees Told to Pause Work With ‘Foreign Nationals’ An internal email obtained by WIRED shows that NOAA workers received orders to pause “ALL INTERNATIONAL ENGAGEMENTS.”

Interference of Trump/Musk with @noaa.gov is very worrying, and is having immediate effects on collaborations, such as participation in @icesmarine.bsky.social work.

How does DeepSeek R1 really fare against OpenAI’s best reasoning models? We run the LLMs through a gauntlet of tests, from creative writing to complex instruction.

"we put each DeepSeek response against ChatGPT's $20/month o1 model and $200/month o1 Pro model, to see how it stands up to OpenAI's "state of the art" product as well as the "everyday" product that most AI consumers use." arstechnica.com/ai/2025/01/h...

OpenAI partners with Kakao to expand AI services in South Korea This was the second partnership deal signed this week between the ChatGPT developer and a high-profile Asian firm as it aims to expand its Stargate initiative.

Love the 100 ducks hands down

Critics say new European Union bans on artificial intelligence have too many loopholes that allow European police and migration authorities to use the technology to help track perpetrators of serious crimes.

OpenAI’s new agent can compile detailed reports on practically any topic In just minutes, Deep Research can produce reports that would take humans “tens of hours” to complete.

OpenAI has launched a new agent capable of conducting complex, multistep online research into everything from scientific studies to personalized bike recommendations at what it claims is the same level as a human analyst.

Seems like the USA response to DeepSeek is to attack the achievement instead of say "wow nicely done"...

H5N1 Bird Flu Spreads Rapidly Through California Dairy Herds

The USDA has confirmed that five more dairy herds in California are infected, bringing the total number to 732.

As of now, 74% of the state's dairy herds have tested positive for the virus.

Musk-Altman Feud Reaches White House With Battle for Trump’s Approval The president’s embrace of rival Sam Altman sends a not-so-subtle message to the Tesla CEO.

Abraham Lincoln had his “team of rivals.” President Trump is going to have dueling entrepreneurs.

Five things scientists can do to fight the rise of fascism. Access to trustworthy information is among the most important preconditions for safeguarding democracy.

The freeze of the NIH is just the latest culmination of the right's long war on science, education, and democracy.

Here are some of my ideas for what I think scientists can do about it. 🧪 conservechange.medium.com/five-things-...

So the entire country is about to get a taste of the medical neglect experience 😟

Not loving this

NIH appears to have canceled/postponed all of its study sections—the independent review panels that approve federal grants for health research.

Such grants fund the work/salaries of 300k people at more than 2,500 institutions

DeepSeek-R1 and exploring DeepSeek-R1-Distill-Llama-8B DeepSeek are the Chinese AI lab who dropped the best currently available open weights LLM on Christmas day, DeepSeek v3. That model was trained in part using their unreleased R1 …

DeepSeek released a whole family of inference-scaling / "reasoning" models today, including distilled variants based on Llama and Qwen

Here are my notes on the new models, plus how I ran DeepSeek-R1-Distill-Llama-8B on my Mac using Ollama and LLM

"The OpenAI API is exclusive to Azure..."

Secure and Internet 🤔

I didn't see where Microsoft passed on this.
