Published estimates of AI energy use per prompt (~0.3 watt-hours) appear reassuring small. But they are increasingly disconnected from how we actually use AI. Modern agentic tools use around 600 times more energy per prompt, as I discuss in my latest over at The Climate Brink www.theclimatebrink....

These stories are often being presented as "cunning AI escapes its test room". I can't see why. It's simply the case that the sandbox was not well isolated by the testing companies. Put the agency and responsibility where it belongs. cyberscoop.com/anthropic-cl...

Anthropic says its AI accidentally hacked three companies during safety tests

Anthropic revealed its Claude AI models accidentally breached three real companies during safety testing after a vendor configuration error exposed live systems.

This is a really great and well researched article for anyone interested in current AI and its limitations. Did you know you can replace the text in "reasoning" trace with something else without changing performance? These models don't work for the reasons we think they do.

It's that time of year again.. No-one has demonstrated the evolutionary significance of epigenetic inheritance, at least not in animals, primarily because that is very different from just showing a transgenerational effect can occur. theconversation.com/updating-dar...

Updating Darwin: biologists are returning to an older theory to explain anomalies in evolution

To make sense of some characteristics that species exhibit from birth, you have to turn to an old discredited theory known as Lamarckism.

Enter INSPYRE. This massive NASA-led campaign is gearing up to fly through pyroCb exhaust to study the global consequences of these fire storms. @nature.com got an inside look at this mission taking off tomorrow in Colorado...🧪🌍 www.nature.com/articles/d41...

First mission to fly through monstrous ‘fire clouds’ about to take off

The towering formations appearing over severe wildfires in France and Oregon loft smoke so high they have global consequences.

Firefighters in Oregon, Spain, and now France (?!) are battling wildfires big enough to generate pyrocumulonimbus clouds. These fire storms are treacherous on the ground. But scientists are concerned about the *planetary* consequences of injecting so much smoke into the upper atmosphere...🌍🔥🧵

This image shows a pyrocumulonimbus cloud rising from the 2022 Mosquito Fire, burning near the Middle Fork American River and Foresthill, California, taken in the afternoon of September 08, 2022.

Some fertility clinics offer to furnish clients’ embryos with donated mitochondria to help treat infertility -- this hasn't been proven in rigorous clinical trials and may have safety risks. Scientists who spoke to @nature.com are alarmed. By @edwrdchen.bsky.social www.nature.com/articles/d41...

Fertility clinics are offering young mitochondria in controversial fertility technique

Researchers are alarmed that the procedure, which has not been rigorously studied, is advertised by clinics around the world.

The first volunteer was vaccinated against Ebola only 68 days after the WHO declared the current outbreak a public health emergency of international concern We spoke to the study's lead scientists about how they were able to move so fast go.nature.com/4x7jMN0

Inside the high-stakes race to develop an Ebola vaccine for an escalating outbreak

The University of Oxford has already vaccinated its first clinical-trial participant. The study’s lead scientist Teresa Lambe tells Nature how they were able to move so fast.

I suffered through Kratsios' answer to Science: the Endless Frontier. The NYT summary is good, but there's more to it. And I should say that I welcome improvements to the scientific enterprise (which is why I'm participating in @alondra.bsky.social and Jenny Reardon's Public's Science project). 🧵

Trump’s Plan for Science: More Money for A.I., Less for Universities (Gift Article)

Michael Kratsios, President Trump’s science adviser, proposed overhauling how the government funds research. Democrats said Mr. Trump’s actions had weakened science.

Living systems, from bacteria to plants to mammals, all emit a faint light, a byproduct of metabolic activity in cells. Could these 'biophotons' be subtle markers of health? Might other cells even react to light signals? by @jomarchant.bsky.social | @nature.com www.nature.com/articles/d41...

All living things emit a faint glow. Could this light be useful?

Ultra-weak ‘biophotons’ might be used to diagnose disease, or could even represent a new signalling mechanism in cells.

No. Someone did a TINY trial on 47 overweight people, 26 of whom had restricted eating hours. They presented their non peer reviewed findings at a conference. Science journalists who should know better bigged up the press release. www.theguardian.com/science/2026...

Restricted eating hours may reduce cognitive decline in older age, researchers find

Preliminary study shows older people who avoided food four hours before bed did better in problem solving tests

A simple but (I think) compelling re-analysis of a paper that Director Bhattacharya frequently cites in his talks to claim that NIH-funded researchers no longer pick up the newest ideas. Dr. Bishop concludes the opposite using the same data. The original conclusion was contrary to my experience.

Further analysis of Packalen & Bhattacharya article, where they claimed #NIH-funded research was slow to pick up on new ideas. I argue that their approach is flawed, and I present an analysis that shows the exact opposite. pubpeer.com/publications...

“NSF has now pulled back $300 million from two of its divisions: mathematics and physical sciences, and computer and information science and engineering. Programme officers…at the NSF, have pulled back 150 proposals that have already passed peer review to free up the money”

White House science policy captured headlines this week, with the announcement of awards for its flagship AI program, Congressional hearings, and a Vannevar Bush-esque report "Science: A New Golden Age." We fashioned the news into one big story—incl. key updates at NSF. Reported w/ Kaia Glickman:
