In this issue of Nature (I read on my way to Warwick), a pre-COP30 tribune, to be opposed to later issues!, with a positive take on the impact of the Trump Administration ignoring the conference, with the advances made by China and India (with a surprising 50% of “installed electricity generation capacity coming from non-fossil sources”, if more critical on Brazil’s efforts than the subsequent tribune by the Brazilian undersecretary for ecological transformation for environment, plus a tribune on the ambiguous terms used by countries to secure access to “critical” minerals, in tune with the on-going muscle-flexing attitudes of China and the US. Although the comment is more focussing on the universal access to minerals than to the protection of the workers extracting it and to the environmental impact of it. Followed though by another comment on the climate impact(s) on mining as (no longer) extreme weather events hinder mining all over the (mining) world.

A reflection on China’s 5y plan for science and its reaching a $500 billion annual investment in R&D, predicting (with a large confidence margin) that it will become the #1 power in sciences and technology in the coming decade. I am actually surprised that China has not yet achieved this goal for semi-conductors. And a tribune on the mixed signal of Takaichi Sanae becoming Japan’s first female prime minister, for science as a whole and for gender equity. (My take being that her having UK’s first female prime minister, Margaret Thatcher, as a role-model is not particularly promising. Just like the projection of Marine Le Pen on the verge of becoming France’s first female president does not carry any optimistic message!)

A light entry on a chemical analysis of the specifics of koti luwak (or civet coffee) that does not tell much, beside civet  digestion  adding caprylic and capric acids making beans lower in proteïns and higher in fat. Not yet reaching the goal of “leaving the animals out” from producing this luxury coffee ($75 a cup!).

An article on the shrinking number of US PhD admissions (in some colleges) conflicting with another article in a later issue of a stable influx. And a rather shallow article on the creativity or lack thereof of AI, along with the high sycophancy of LLMs,  to be opposed to a thoughtful reflection on how AI is radically changing the PhD experience and focus, if almost shelving statistics as a thing from the past! But insisting on graduates keeping their ability to check for the validity of their (AI’s)  statistical conclusions!! And another entry on the systematic dismantling of US federal scientific agencies like EPA, CDC, NASA, NOOA, NIH, &tc., by Trump -2.0, which beyond terminating staff contracts in huge proportions is culling the independence of these agencies. With generational impacts on science, training, and evidence-based policies.

A Where I work column featuring a pangolin treated by a Singapore vet, Charlene Yeong. (Unfortunately said pangolin was euthanised after the surgical intervention.) And a book review on the background and motivations of Francis Crick,  just prior to his collaborator James Watson passing away. As noted by the author, Cobb, as MRC staff and later non-resident fellow of the Salk Institute for Biological Studies in San Diego,  “Crick never had to teach or grapple with university administration: he applied for a grant only once in his life.” And concludes that he was not a saint or a hero but “an extraordinarily clever man with limits to his interests and perception”.

NobAIl prAIzes

I am quite surprised that the NobAIl committee did not select ChatGPT‘s Sam Altman for their literature prize—since he made a reality of monkeys typing at random on a typewriter, hence bound to a.s. produce past and future masterpieces—, now betting on Twitter’s Dorsey, Williams and Stone for their peace prize— for achieving worldwide harmony if within each single-minded community in only 140 characters—, and Amazon’s Jeff Bezos for their Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel—for produing the ultimate monopoly of a single worldwide convenience store—, given their picks for physics—with spin glass Ising models that have always sounded to me like the worst possible illustration for MCMC techniques— and chemistry—for a deep learning predictor of protein structures, built by large teams and numerous CPU hours, achieving high success rates if not perfection, but prediction is not explanation, reminding me of Nietzsche’s “physics, too, is only an interpretation and exegesis of the world (to suit us, if I may say so!) and not a world-explanation”—… Keeping their sharp focus on AI’s, corporate funded research, and male recipients… (As coïncidences come, I am currently reading a book of the literature 2024 Nobel recipient, Han Kang, The Vegetarian, that I find stunning and immensely original!)

Guiana impressions [#2]

As in other oversea French territories, Guiana is a mix of reproduction of some metropolitan features (e.g., the postoffice, the gendarmerie, the signage, the large malls with French brands like Carrefour and the same products as here, the many boulangeries) and of local specificities or idiosyncrasies (e.g., very well maintained roadsides, haphazard garbage collection, convenience stores overwhelmingly operated by people of Chinese descent, hardly any regulation on guns, hunting, or bushmeat for non-protected species). Car wrecks are left along the roads, while the driving code there reminded me of the 80’s! Meaning risky overtakes, moppets with no lights and moppet drivers with no helmet. I also drove there possibly the worst ride of my life, over the 50km between Roura and the harbour on Kaw marshes, as the formally (or formerly?) paved D6 road is littered with potholes that are rarely avoidable and often quite deep. The drive back in the night, the rain and the fog was a nightmare!

We visited the launching site of ESA, Kourou, an impressive structure over a huge territory. But missed the James Webb launch by six hours, only catching the exhaust fumes of the rocket when we were approaching Cayenne (after a rather uncomfortable flight between a massive and man-spreading left neighbour and a reclining-to-the-max front neighbour). And missed a jaguar crossing the road by being in the “wrong” ESA bus! (Unless this is a usual line of the tour guide.)

As Amazon France does not truly work in French Amazonia (another idiosyncrasy!), for obvious cost and delay resaons, bookstores in cities like Cayenne and Kourou are terrific and hopefully standing a better chance of surviving. When we spent an hour in La Case à Bulles, the place was crowded! (As I forgot my regular Olympus camera at home, I would have loved to get Amazon delivery. Instead I bought a basic Kodak camera from the local supermarket, which returned most of these blah pictures before the batteries prematurely died.)
