COVID sucks[0]. I might have died if I hadn’t already been vaccinated and boosted. As it was, I merely longed for death.
Take your vaccinations. You could die without.
[0] Seriously, the headache and fever and heart arrhythmias were the most afraid I have ever been of dying, for two days straight. And unable to sleep even a bit in all that time.
Alienoid November 15, 2022

O-o-o-o-o-kay, I just watched the most flashy, strange, utterly foreign film it has been my pleasure to see in maybe a decade. “Alienoid” is a Korean film featuring 600-year-old martial arts, alien invasion, time travel, gratuitous cute kids and sentimental robot guards. Also, downtown Seoul is sliced and diced by alien spaceships.
Ancient magicians fight alien criminals in non-stop action. Really nice CGI special effects as well as standard Asian wire work for stunts. It all rolls along so quickly you can barely read the subtitles.

“In other news, I understand the new owner of TWTR is employing his valuable CEO bandwidth in trolling sitting US Senators, which I suppose is more evidence that the true difference between men and boys is the price of their toys.”–an American expat in Switzerland, where presumably the authoritarian regime which will soon envelop the USA will not be able to get him without extraordinary rendition.
We now resume your otherwise apolitical blog.

30% of FDA regulations are not made from data
According to a team of US researchers their results (based on an examination of drug safety signals identified by the FDA from 2008 to 2019) show that the FDA is either taking regulatory measures on information that has not been made public or that more comprehensive safety evaluations may be required when possible safety signals are identified. Less than a third (30%) of regulatory actions were corroborated by at least one relevant published research study
Homework: “Characterization and corroboration of safety signals identified from the US Food and Drug Administration Adverse Event Reporting System, 2008-19: cross sectional study” by Meera M. Dhodapkar, Xiaoting Shi, Reshma Ramachandran, Evan M. Chen, Joshua D. Wallach and Joseph S. Ross, 5 October 2022, The BMJ.

Eight harvests from one rice planting in China and Uganda
New strains of rice are being used in Uganda and China, which can be harvested for several years (as opposed to current practice of planting yearly). With few exceptions, perennial rice yield was equivalent to annual rice over the first four years. Yield began to drop off in the fifth year due to various factors, leading the researchers to recommend re-sowing perennial rice after four years.
But because they didn’t have to plant each season, farmers growing perennial rice put in almost 60% less labor and spent nearly half on seed, fertilizer, and other inputs. This is a potential game changer for poorer farmers.

Carbon nanotubes grown vertically–in quantity
The Department of Energy’s Lawrence Livermore National Laboratory (LLNL) are scaling up the production of vertically aligned single-walled carbon nanotubes (SWCNT), useful in rechargeable batteries, sporting goods, and auto parts, boat hulls and water filters.

Buchsbaum, Eric R. Meshot, Melinda L. Jue, Kuang Jen Wu and Francesco Fornasiero, 29 September 2022, Carbon.

Treatments for senescent cells
University College London scientists have discovered a new mechanism that slows down and maybe even prevents the normal aging (of immune cells only; don’t get too excited).
A telomere transfer reaction between two types of white blood cells, in ‘extracellular vesicles’ (small particles that facilitate intercellular communication) had an antigen-presenting cell (APC), consisting either of B cells, dendritic cells, or macrophages, function as a ‘telomere donor’, to the T lymphocyte – the telomere recipient cell. Upon transfer of these telomeres, the recipient T cell became long-lived and possessed memory and stem cell attributes, enabling the T cell to protect a host against lethal infection in the long term.
The telomere transfer reaction extended certain telomeres about 30 times more than the extension exerted by telomerase.
