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”.

mass decimation of U.S. science

red state – blue state – vaccinated state – unvaccinated state

The New York Times published an article demonstrating the partisan separation between US Democrats and Republicans by regression lines. As the one above, regressing the proportion of vaccinated on the proportion of Trump voters but no scale on the first axis. But no correction for age composition or population density. And the one below, plotted at the county level, which seems quite meaningless given the spread of red dots in Wyoming.

Still, there is a clear opposition between places (counties) that voted more than 70% Trump (representing 33M people) and those that voted more than 70% Biden (more than 58M people), even though county density, age composition, and earlier deaths from COVID should also be accounted for. But the vaccination rate also exhibits this opposition, with a 1.65 ratio between the first and last decile of the blue counties.

Influenza, anywhere?!

Everyone should take everyday preventive actions to stop the spread of germs, including frequent hand washing and people who are sick should stay home and avoid contact with others in order to limit further spread of the disease [CDC Public Guidance].

As I am getting ready to take my plane for the 3rd Rimini Bayesian workshop mentioned on that post (no, I haven’t yet changed my slides!), I am [rather idly] wondering why we do not hear more about the H1N1 pandemic. Checking on the site of the World Health Organisation (WHO) shows a widespread repartition of the flu since most countries are hit (I spotted Haiti and most of Africa missing from the list, but this may be due to a lack of proper reporting rather than no case so far).

Novel influenza A (H1N1) activity is now being detected through CDC’s routine influenza surveillance systems and reported weekly in FluView [CDC Surveillance].

While I see the point in not panicking people by adopting extreme measures like those taken in Mexico (too late) during the first weeks of the outbreak, it seems to me that nothing is done at the moment, at least as perceived through my everyday life. I do not see people wearing masks when they cough, washing hands more regularly and so on… It sounds like the [maximum] Phase 6 level announced by the WHO has no visible impact. Is it because the disease actually has less impact than previously thought? Mais que fait la police?!
