Average person will be 40% poorer if world warms by 4C, new research shows (theguardian.com)
Economic models have systematically underestimated how global heating will affect people’s wealth, according to a new study that finds 4C warming will make the average person 40% poorer – an almost four-fold increase on some estimates.

The US Assault on Science: National Academies Letter (nytimes.com)
Some 1,900 leading researchers accused the Trump administration in an open letter on Monday of conducting a “wholesale assault on U.S. science” that could set back research by decades and that threatens the health and safety of Americans.
New blood test checks for Alzheimer's and assesses progression, study (theguardian.com)
Researchers have developed a blood test for patients with thinking and memory problems to check if they have Alzheimer’s and to see how far it has progressed.
Glutamate Unlocks Brain Cell Channels to Enable Thinking and Learning (neurosciencenews.com)
In an effort to understand how brain cells exchange chemical messages, scientists say they have successfully used a highly specialized microscope to capture more precise details of how one of the most common signaling molecules, glutamate, opens a channel and allows a flood of charged particles to enter.

Bell Labs Holmdel Complex (wikipedia.org)
The Bell Labs Holmdel Complex, in Holmdel Township, Monmouth County, New Jersey, United States, functioned for 44 years as a research and development facility, initially for the Bell System and later Bell Labs.[3] The centerpiece of the campus is an Eero Saarinen–designed structure that served as the home to over 6,000 engineers and researchers.[4] This modernist building, dubbed "The Biggest Mirror Ever" by Architectural Forum due to its mirror box exterior, was the site of a Nobel Prize discovery, the
Circuit Tracing: Revealing Computational Graphs in Language Models (Anthropic) (transformer-circuits.pub)
We introduce a method to uncover mechanisms underlying behaviors of language models. We produce graph descriptions of the model’s computation on prompts of interest by tracing individual computational steps in a “replacement model”. This replacement model substitutes a more interpretable component (here, a “cross-layer transcoder”) for parts of the underlying model (here, the multi-layer perceptrons) that it is trained to approximate.
Installing air filters in classrooms has surprisingly large educational benefits (2020) (vox.com)
An emergency situation that turned out to be mostly a false alarm led a lot of schools in Los Angeles to install air filters, and something strange happened: Test scores went up. By a lot. And the gains were sustained in the subsequent year rather than fading away.

US scientists lost $3B in NIH grants since Trump took office (arstechnica.com)
Since Trump took office on January 20, research funding from the National Institutes of Health has plummeted by more than $3 billion compared with the pace of funding in 2024, according to an analysis by The Washington Post.
Is AI the new research scientist? Not so, according to a human-led study (warrington.ufl.edu)
In a comprehensive study examining the capabilities of artificial intelligence in academic research, University of Florida researchers have found that while AI can be a valuable assistant, it falls short of replacing human scientists in many critical areas.
The replication crisis may also be a theory crisis (2019) (arstechnica.com)
But methods are only part of the problem, as Michael Muthukrishna and Joseph Henrich argue in a paper in Nature Human Behaviour this week. It’s not just that individual puzzle pieces are low in quality; it’s also that there’s not enough effort to fit those pieces into a coherent picture. "Without an overarching theoretical framework,” write Muthukrishna and Henrich, “empirical programs spawn and grow from personal intuitions and culturally biased folk theories."
ChatGPT is shifting rightwards politically (psypost.org)
An examination of a large number of ChatGPT responses found that the model consistently exhibits values aligned with the libertarian-left segment of the political spectrum. However, newer versions of ChatGPT show a noticeable shift toward the political right. The paper was published in Humanities & Social Sciences Communications.
Healthy Diets Linked to Holistic Healthy Aging in Long-Term Harvard Study (thecrimson.com)
Researchers at the Harvard T.H.

Indiscriminate firings. Terminated grants. Cancelled programmes. The barrage of actions by US President Donald Trump has shocked the country’s research community over the past two months. Yet, much of it was planned out years in advance and laid out publicly.
Plants can take up CWD-causing prions from soil in lab. What happens if eaten? (cidrap.umn.edu)
When Christopher Johnson, PhD, set out to study whether lab mice fed prion-contaminated plants developed neurodegenerative disease, he expected the plants to take up only small prion clusters, but they absorbed large clusters characteristic of prion diseases in deer and other animals.
