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”.

and it is getting worse… [verbatim]

“Because of other countries testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis”DT,  30 Oct. 2025

“The Green New Scam would have killed America if President Trump had not been elected to implement his commonsense energy agenda – which is focused on utilizing the liquid gold under our feet to strengthen our grid stability and drive down costs for American families and businesses”Taylor Rogers, White House spokeswoman, 31 Oct

“It’s not that I want [Chinese national students], but I view it as a business. [Draconian cuts to hiring international students could] destroy our entire university and college system.”DT,  17 Nov. 2025

“The president being frank and open and honest to your faces [by cutting off Catherine Lucey by `Quiet, piggy!´], rather than hiding behind your backs, is, frankly, a lot more respectful than what you saw in the last administration.” Karoline Leavitt, press secretary, 18 Nov 2025

“You’re mentioning someone [Jamal Khashoggi] that was extremely controversial. A lot of people didn’t like that gentleman that you’re talking about. Whether you like him or didn’t like him, things happen. But [Mohammed bin Salman] knew nothing about it. You don’t have to embarrass our guests.”DT,  19 Nov. 2025

“Do you think the French [students in the US] are better [wrt spying and stealing intellectual property], really?… I’m not so sure” DT,  10 Nov. 2025

Nature tidbits [23 October 2025]

In this October issue of nature, plenty of the “usual” topics, namely AI and Trump.2.0 wrecking balls, along with two cosmology entries that related to my trip to the early universe last week, and a pros-and-cons opposition about animal testing,

a discussion on the nature of the “little red dots” that have been recently observed and whose nature remains open, the most popular explanation (I was given during lunch) being black holes surrounded by gas (even though I cannot understand why the gas is not attracted by the black hole!) [and would have produced a more exciting cover!]

a review of the recent book Discordance: The Troubled History of the Hubble Constant by Jim Baggott, entitled Why we still don’t understand the Universe — even after a century of dispute! A review that regrets that more time is spent on the Hubble “constant” (which varies with time!) rather than more controversial issues like dark matter and dark energy (And strangely bemoans that the book is focussed on scientific developments, missing sociological ones. Duh?! (Bonus for a picture of suit-and-tie Edwin Hubble sitting at the centre of a telescope),

two entries on the well-being [or lack thereof] of PhD students, with nothing particularly surprising (eg, inclusivity and respect help!), and Brazil, Australia and Italy ranking top locations but in a comparative study that does not mention France (as often in international comparisons found in Nature) despite the place being in the top 10 countries delivering PhD degrees, not that I believe PhD students are particularly well-treated in French academia!, the (unexplained) surprise being Italy ranking so high given the close resemblance between the two countries (low stipends, shortage of postdoc and permanent positions, high teaching loads for the advisor, limited travel budgets),

a conference (purposedly) made of AI-written papers reviewed by AI referees, Agents4Science 2025, how universities are rushed into adapting to AI-fluent students, whose skills are changing, and the rise in fake authors produced by paper mills, with a limited range of acceptable solutions,

why Trump 2.0‘s blackmail on pharmaceutical companies is counter-productive and likely to slow down progress, and why his massive increase of highly qualified scientists is shooting (or nuking) USelf in the foot, given the huge proportion) of im/emigrated Nobel prize winners (for physics, chemistry, and medicine), along the (post-) Nobel prize in economics is a direct or indirect reply to this regression by awarding the Prize to economists who worked on the importance of creativity and science on growth (not very surprising at first look!)

Le Monde [festival]

Posted in Books, pictures, Travel, Wines with tags , , , , , , , , , , , , , , , , , , , on October 6, 2024 by xi'an


Last weekend we biked to the Festival du Monde, which holds a series of events and interactions with the journal team, if not at the level of The New Yorker Festival. In and around the modern building of Le Monde, near Gare d’Austerlitz. As most sessions were already booked, with only one entry left for my wife (on the incoming US Presidential Elections), I stayed outside on the small plaza and listened to (blah) bands, tasted yummy olive oils from Brazil and Uruguay that were part of a Southern Hemisphere oil competition (Brazil won!), a tepid empanada, a comfort plantain banana bowl and Bordeaux red wine aged in clay amphoras! While speaking with the winemaker was very nice, from the mix of Petit Verdot and Merlot (even though the vineyard page mentions Malbec!), to the local making of the amphoras, the outcome (of this recent experiment) was not that great. (Still hoping for a Georgian orange wine experiment!)
