Read The Sparrow, the 1998 Arthur C. Clarke Award by Mary Doria Russell, a profound and mesmerizing book (even though it took me a while to go through it as my bedside read!). It is a science-fiction book (since the mostly Jesuitcharacters travel to another planet in Alpha Centauri) that involves a lot of philosophy, religion, anthropology and linguistics. There are weaknesses in the science half of science-fiction and too much space musing over the contradiction inherent to the celibacy of Catholic priests, but I strongly enjoyed this book, maybe due to my Catholic upbringing!, and its highly unexpected conclusion. (I am however uncertain about pursuing with the sequel, as the central character returning to the planet sounds like the ultimate torture.) Also read Since we fell by Dennis Lehane, which I find terrible at so many levels, from a complete lack of realism in the crime scenes and in the way coïncidences keep happening, to the endless introspection of the main character, Rachel, to the cardboard consistence of most characters…

Started making skyr, the Icelandic style cottage cheese that I usually eat as yogurt. It is fairly straightforward, with a very few steps and ingredients (fat-free milk, renet, and… skyr!), but an overall 15 hour preparation range, and it does not always turn into the expected curded outcome (in which case it is close to a lassi, लस्सी). I have not yet analysed the sources for this variable outcome, possibly the different starters I used. I also cooked a batch of okonomiyaki, rescuing an out-of-date bag of okonomiyaki batter as I had some spare cabbage in the fridge.

less bats, higher mortality

“…farmers compensated for bat decline by increasing their insecticide use by 31.1%. The compensatory increase in insecticide use by farmers adversely affected health—human infant mortality increased by 7.9% in the counties that experienced bat die-offs.” Eyal G. Frank

A Science article by Eyal Frank got a lot of press last week for linking US bat population plummeting (up to 70%) due to the “white nose syndrom” (an invasive fungus) impacting bats since 2006 (through premature awakening from hibernation) and therefore agriculture, to a huge (8%) rise in infant mortality in the impacted regions, resulting from a jump in the use of insecticides… (The statistical model behind the predicted mortality is a linear model for all dependent outcomes, insecticide use, crop yield, and infant mortality. With plenty of precautions to separate infected counties from non-infected ones and to eliminate exogenous causes.)

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!

local parakeets
