Nature tidbits [21 Aug 2025]

The cover of this Nature issue is a fake!, being an artist’s rendering of a supernova (2021yfj) before it exploded, with the core exhibited as rich in silicon and sulfur. (The heaviest element in stars is iron, resulting from the fusion of the above. When the iron mass exceeds a limit, the star collapse into a neutron star or a black hole.)

On the Trump 2.0 administration’s attack-on-science front, an editorial exposes the irresponsibility of cancelling grants for mRNA studies (which Trump 1.0 supported during the COVID crisis). And a longer article points out the radical switch in managing federal grants, committees moving from scientists to political appointees, searching for “anti-American values”… And another one on the backlash following the report from said administration about climate change and global warming. (As blogged recently.)

At a more conceptual (and international) level, an article questions the usual stand on declining birth rates as being problematic. While acknowledging that public incentives have a highly variable mileage, the article remains vague on how supporting an ageing population while keeping an homogeneous welfare support will prove feasible. A second socio-economic article muses about the lack of a downward curve in the cost of electric cars, despite the drop in battery costs, pointing out the inefficiency of state support that creates profit bubbles for the manufacturers. Stricter policies on combustion vehicles similarly seem inefficient, given the violent reactions of car owners (as in the Gilets Jaunes revolt). The EU has alas recently backed down on its goal of prohibiting new combustion engines by 2035.

In shark contrast, a review paper document the rising probability of a climate catastrophe induced by the melting Antarctica, which could prove of a higher magnitude than the melting Arctic. (Even though the introduction article is rather confusing, mixing this issue with the pollution brought by Antarctic tourism and mentioning indigenous populations that do not exist on the 7th Continent).

And on the (weekly) AI front, the announcement of the downloadable gpt-oss from OpenAI, which I plan to check. And the debate on whether or not AI generated papers can plagiarise, again a poorly focussed article mostly missing the issues of the scientific worth of such papers (and the basic fact that they 100% plagiarise the literature dataset they learned from!).

it was just an accident […unlike the Trump administration returning Iranian refugees to Iran]

 “In the late 1980s, LeCun, then a researcher at AT&T Bell Labs, developed a powerful neural network that learned to recognise handwritten zip codes by training on thousands of examples. A parallel development soon unfolded at Harvard and Brown. In 1995, Zhu and a team of researchers there started developing probability-based methods that could learn to recognise patterns and textures (…) and even generate new examples of that pattern. These were not neural networks: members of the “Harvard-Brown school”, as Zhu called his team, cast vision as a problem of statistics and relied on methods such as “Bayesian inference” and “Markov random fields”. The two schools spoke different mathematical languages and had philosophical disagreements. But they shared an underlying logic – that data, rather than hand-coded instructions, could supply the infrastructure for machines to grasp the world and reproduce its patterns – that exists in today’s AI systems such as ChatGPT.”

A statement from the Royal Statistical Society on the dismissal of the Commissioner of Labor Statistics, Dr Erika McEntarfer

Posted in Books, Statistics, University life, Wines with tags , , , , , , , , , , , , , on August 7, 2025 by xi'an

“The Royal Statistical Society (RSS) notes with concern the dismissal of Erika McEntarfer as Commissioner of Labor Statistics by US President, Donald Trump, at a time when the global economy is experiencing significant disturbance.

The United Nations’ Fundamental Principles of Official Statistics establishes international professional and scientific standards for the production of official statistics. The RSS, as one of the world’s leading statistical societies and with a membership that includes official statisticians from many countries, is keenly interested in the adherence to these standards across the world to ensure quality and integrity.

Any concerns regarding data or methodology should be independently evaluated to ensure credibility is maintained. The dismissal undermines international trust in US statistics, which has ramifications well beyond policy decisions within the US, with impacts on global confidence in the world economy.

The RSS is against all forms of political interference in the production of official statistics and urges President Trump to ensure that the nonpartisan integrity of the position is retained. Furthermore, reassurance is needed to ensure that statisticians working for federal agencies have confidence to continue producing the objective statistical information that enables those in power to gain the trust of their communities.

These actions are essential to ensure a healthy democracy in the US, and to maintain international credibility in its statistics.”
