Scientists and the general public have long dismissed the cognitive abilities of cows, pigs, and other livestock. But farm animals are capable of much more than we think.

Marine #microorganisms are crucial for #ocean health.

#Bacteria, #archaea, #fungi, #algae and #viruses make up most of the biomass in the seas and form the base of marine food webs.

They support nutrient cycling and drive crucial biogeochemical processes, including key steps in the carbon, nitrogen and silicon cycles.

Ocean modelling must evolve to take their biological complexity into account.

Chromosome-Scale Genome Assembly of the Solitary Parasitoid Wasp Microplitis manilae Ashmead, 1904 (Braconidae: Microgastrinae) https://doi.org/10.1093/gbe/evad144 #science #evolution #biology #genome #evolgen_paper
The genomic characteristics of Microplitis manilae. (a) Hi-C contact map showing the interactions among 11 pseudochromosomes. (b) Circos graph of the genome characteristics of M. manilae. Element distribution in 100 kb sliding windows, from outer to inner circles: length of 11 chromosomes, GC content, density of protein-coding genes, DNA transposons, SINE/LINE/LTR retrotransposons, and simple repeats. (c) Chromosomal synteny blocks between M. manilae and Cotesia glomerata/Aphidius gifuensis. The Mman8 and Mman11 had better syntenic relationships with Cglo8 and Cglo9, respectively. The abbreviations “Mman,” “Cglo,” and “Agif” indicate chromosomes of M. manilae, C. glomerata, and Aph. gifuensis.

How did #eukaryotes evolve for extreme temps? https://www.futurity.org/high-temp-eukaryotes-2972442-2/ #protists

#ExtremeEnvironments offer an unprecedented opportunity to understand #microbial #eukaryotic #ecology, #evolution, and #genome #biology: Hannah Rappaport & Angela Oliverio https://www.nature.com/articles/s41467-023-40657-4

“several lineages of #amoebae were often recovered from extremely high temperature environments. Studying those lineages may yield great insight into how eukaryotic cells can adapt to life in extremely hot environments.”

I have a serious need to know as osculation, for me, has always carried great risk, #autoimmunesystem highly compromised.
The first few months of a new romantic relationship is fraught with a horrid cascade of immune response symptoms. And yet, I still do it!!! It's a really difficult one to resist.

While we are still trying to find ways to clean up problems like oil spills in the ocean, microorganisms in the seas have their own insights to impart.

Oil rich soil from the Guaymas Basin has provided German scientists understanding of a mechanism by which archaea in the Alkanophaga break down alkane molecules and thus degrade petroleum through oxidation.

This is a 440-pound heart from a blue whale, the largest known animal to ever exist. The heart was so large that technicians had to douse it in 1,000 gallons of formaldehyde. Read more about it here: https://www.smithsonianmag.com/travel/painstaking-process-preserving-blue-whales-heart-180964038/

#introduction content continued! as a follow on to nematoduino, I made nematode.farm, which is a (very) simple browser based game where the “opponent” is many instances of the emulated C. elegans nematode. I think this may be the first game ever where enemy AI is based on an emulated organism.
written in C, SDL2, and compiled in webassembly 
can play here (need arrow keys)

More #introduction content!
I’m also somewhat known porting a C. elegans nervous system model (connectome) to the Arduino Uno, so it could be used in very low cost or resource constrained platforms.
Yes, this is a robot that thinks it’s a worm, lol

Hi! #introduction ! I'm a #phd student in #chemistry ! I study #nanoparticle #liquidcrystal self-assembly, which has implications in our understandings of #biology nanostructures, #materials chemistry, and #nanotechnology

I’ve been #scicomm ing my #research on #twitch - I'm developing #3dprinting inks from seaweed and other #biomaterials !

I interview scientists weekly, so if you're interested, let me know! I’d love to have you
