Many bits of interest in the 25 July issue of Nature that stayed under a pile of journals for PNW reasons! Even though the cover is rather off-putting…

  • A call by the editors (and computer scientist Cal Newport) for scientists to “stop, drop, and think” (and the paperback version of Newport’s Slow Productivity has a nice cover that looks very much like Moraine Lake in Banff National Parc!)
  • Another call by a Science Po’ sociologist to the (then highly prospective) French government to increase research budget for French universities, which is not particularly original since this is a constant line on all unions’ desiderata, except for the argument that it would make a tuition fees increase more palatable, and to leave more freedom to researchers, with the oft-used argument that “fundamental research may have unexpected implications”. Except that a massive public deficit is going to impose budget squeezes in all spending lines of the Barnier government.
  • Worries of Indian and non-Indian demographers about the continued postponement of India’s national census, with the latest one dating from 2011. With strong repercussions on public policies, especially since the administrative data systems are rarely reliable. The article suggests that more than an estimated 100 million inhabitants are excluded from food subsidies as a consequence. This seems like an opportunity to develop open source alternatives that run the census from indirect observations, bypassing the reluctance of the Modi Government to launch the much delayed census. (Which could have been coupled with the electoral process earlier this year.)
  • An insight on four female “PhD influencers” from the Universities of Pennsylvania, Exeter, Hertfordshire, and Hong Kong (CUHK). Which has a plus side of exposing the life and interests of a PhD student. And a downside of being a social media product, with the many biases that come along posting to the general public.
  • A call for publishing more papers about negative results! Supporting (pre)registration of experiments.
  • A positive book review of The MANIAC of Benjamin Labatut around John von Neumann’s life, analysed by Karl Sigmund
  • A four-page long comment on the importance of preserving scientific US-China relations, despite the growing suspicion in the US that any scientific collaboration with Chinese institutions will benefit Chinese (State) interests. Without falling for a naive approach to such collaborations, and acknowledging the porous boundaries between fundamental and military research, one should acknowledge the great leap forward accomplished by Chinese universities in the past decade that set their researchers at the forefront of science in many fields.
  • A paper related with the cover on model collapse in AIs learning from AI-generated data. Just like MCMC learning a proposal from earlier simulations. A natural consequence of over-fitting.
  • Another paper on the phase (or quantum) transition of the two-dimensional Ising spin glass (model).
  • and the article on predatory conferences I already discussed in August.

Nature tidbits [23/05/2024]

When visiting Warwick last week, I read an issue of Nature in the plane and came across…

…a brand new and ambitious museum in Egypt for Egyptians (and others), incl. the repatriation of many artefacts, while hoping the tragedy of the unique Institute of Egypt, a research centre set up in 1798 by Bonaparte, being destroyed in 2011 by fire during the clashes between Tahrir Square protestors and military forces in Cairo, and finished by firemen flooding the place and its rare books, and remembering the sorry state of the surroundings of the Great Pyramids when I visited them almost twenty years ago,
…Nature editorial on its failing to publish AlphaFold3 code, with corporate knee-jerk newspeak,
…within an article on the “miracle” obesity drug(s), the sobering warning of half of the population turning obese by 2035…
…a Swiss experiment on paying researchers to spot errors in published papers, although I am unconvinced by the argument that paid readers would prove more reliable than benevolent ones,
…AI experts hired by the US Congress providing advice on federal AI legislation,
new achievements in developing quantum internet at the scale of a (so far small) city, a concept I had never met before (and which does not make total sense to me, incl. the appeal of quantum entanglement),
…support or lack thereof of harassed scientists within their institution (which would clearly be in the “lack” branch for my institution!),
…some “careers stories” of faith vs. science, that reports on a survey on how scientists with a religious affiliation experience their religion at work, or not, with some unconvincing arguments towards incorporating religion elements in scientific discussions,
…a (weekly) portrait of a biotechnologist cum fisherman fishing for blue crabs in Pula, Croatia—which we visited eleven years ago—,  an invasive species that he encourages people to eat,

and much more stuff!
