The cover of the 15 Jan issue of Nature is a blurry reconstitution of snapshots from the James Webb Space Telescope, which contributed to uncover these new astronomical objects, deemed to be young supermassive black holes. A notion I only came across recently, during a pre-defence lunch near the Paris Observatory.

Apart from that astronomical advance, Nature puts its focus on the 25th anniversary of Wikipedia. With a tribune bemoaning the insufficient investment of academics in the platform (with mentions of hypocrisy and betrayal). Which sounds rather unfair, since it requires an additional levy on research time, even though I did contribute to a few entries. And recognise the worth of most scientifics pages, as well as the parasitism by LLMs. And an interview of of Jimmy Wales’ about his Wikipedia memoir, Seven Rules of Trust. Kudos to his vision! He sounds rather optimistic about the chances of Wikipedia surviving the tsunAImi, but only if the users keep resorting (and indeed contributing) to the platform rather than accepting the LLM production at fa(r)ce value!

Other entries on

  • LLMs suffering (!) from “anxiety, trauma, shame and post-traumatic stress disorder”, although the arXiv reporting the experiment is criticized by others for anthropomorphising the machines. The danger is more in them inducing real trauma in vulnerable (human) users!
  • LLMs exhibiting aggressive behaviour (if trained accordingly)
  • the oldest evidence on human controlled fires using pyrite (in SE England), 400,000 years ago
  • the rise of academics being harassed (and not only in the US) and six recommendations for protecting our digital security (mentioning organisations such as Scholars at Risk Europe, Expert Voices Together, and Faculty First Responders)
  • a “Where I work” picture of a food scientist at the National Autonomous University of Mexico flipping a tortilla, with fermented ingredients to improve health and combat malnutrition in poor communities

The 23 Feb issue of Nature has several “political” articles, if not the title, which refers to the James Webb space telescope bringing in a wealth of information on exoplanets (through five Nature papers!). Beyond the usual editorial (on the need to help rebuilding Ukraine’s research infrastructure as an introduction to the main article on the way Ukrainian researchers coped with one year of war and destruction) and an opinion piece on the ongoing Nigerian elections and the lack of attention to science and technology), a criticism of (recently released) “disgraced scientist” He Jiankui and his (virtual) invitation at the University of Kent, the impact of the new Twitter on social scientists using its data, an attack on the American Geophysical Union for expelling two members who had held up a banner calling for action during an AGU conference talk, and a lengthy opinion piece on banning AI weapons that starts with a rather unwelcome perspective on the “us versus them” Western attitude about the Russian invasion of Ukraine, and a conclusion calling for the UN ban of autonomous weapons that is likely to have the same impact as a ban on nuclear weapons…

a journal of the plague year³ [lazy we]

Had the opportunity [Xmas gift!] to visit the Botticelli exhibit at the Musée Jacquemart-André in Paris. Besides the sheer beauty of the paintings, while is timeless, I was also impressed by the activity of Botticelli as an entrepreneur and designer, declining his signature on different media and delegating part of the realisation to employees. Read the beginning of the third volume of Raven’s mark, Crowfall, but could not complete the book as the story was terrible and the main character mostly disintegrated (both literally and scenario-wise). Too bad that an initially great if grim universe construction could not keep up till the end. (Involving deities is always risky in this branch of the literature!) Also read another BD taking place near Cayenne and other places we visited, if in the 18th Century.

Watched over a lazy weekend two several admittedly terrible movies whose only appeal was watching in the vernarcular, Major Grom: Plague Doctor, and Minnal Murali. Also was rather disappointed by Don’t look up, because I found the satire too heavy-handed. And hence failing to engage readers about the sloth pace of governments and influencers to face the climate crisis, favouring futile or immediate concerns (as shown by French gilets jaunes putting la fin du mois above la fin du monde, or UK media cycling on BoJo’s partygate when Russia is about to invade Ukraine!). I also presumably missed most of the US-centric undercurrents.
