APS -71st Annual Meeting of the APS Division of Fluid Dynamics - Event - How do wombats make cubed poo?
So, research how wombats make cubic poop may provide a line towards a third method of manufacturing soft cubic solids. Why is it cubic is speculated as due to ease of building piles, since wombats have poor eyesight.

Uncovering the psychoactivity of a cannabinoid from liverworts associated with a legal high | Science Advances
Liverwort perrottetinene is a THC analog with less high, more antiinflammatory properties. May be better suited for medical use compared to medical marijuana, and can be synthesized.

Cheap plant oil can give us healthier salmon
So farmed salmon eating plant diets lack Omega-3 fatty acids, as they usually get that from eating other fish. Farmed salmon can sorta get that back by adding fish oil to their feed, but that costs money. Now, using transgenic plants that put out DHA and fatty acids as feed seems to fill the nutrition gap for farmed salmon.

Recombinant Spidroins Fully Replicate Primary Mechanical Properties of Natural Spider Silk - Biomacromolecules (ACS Publications)
So they got bacteria to build silk proteins with are almost twice as long as real spider silk proteins, thus the doubled protein is now a near match in performance to true spider silk fiber (true spider silk fiber benefits from good protein design and spinner design though). They seem to think it should be possible to use the fusing method to build even longer proteins to up the strength.

Nitrogen fixation in a landrace of maize is supported by a mucilage-associated diazotrophic microbiota
Corn/maize variant that doesn't need fertilizer in poor soil because it has weird aerial root structure actively secreting goop that support nitrogen fixation bacteria, so in theory easier/more sustainable agriculture without fertilizer, but the thing is a bit more tree-like and takes 2-3x as long to grow ears. Still neat though.

Enzymatic construction of highly strained carbocycles | Science
Bicyclobutnae is a pain and expensive to make, so hasn't been seriously researched for rocket propellant research, but using e.coli to make it via enzyme catalyst now makes it a biofuel (biorocketfuel?). 8C boiling point versus cryogenic methane makes for an interesting trade study.

All languages speak syllables at about the same rate. Neuroscientists now know why | Big Think
So there's a reason the motor cortex is involved in language processing, and why most human languages use a 4-5Hz syllable rate. Entrained auditory signals are chunked at about 4.5Hz., motor cortex internally oscillates at 4-5Hz

AuB - Athlete micro-biome Bank
So a former soccor player is collecting athlete poop for human microbiome specimens. Since apparently high performance atheletes seem to have fairly different microbiomes from the average person, this is a source of interest for human biology. Potentially, this could lead to performance enhancement treatments, similar to fecal transplants that current move new gut bacteria into people with no/poor performing gut microbiomes.

A synthetic pathway for the fixation of carbon dioxide in vitro | Science
Artificial CO2 fixation cycle (CETCH) made from a combo of 11 enzymes found across animals and plants appears to be 2-3 times faster and 25% more energy efficient than the Calvin cycle, but outputs a weird glyoxylate (which can be further converted to other stuff but...) rather than glucose so now just need to stuff a synthetic bacterium with DNA to build and operate those 11 enzymes to see if it really is better than photosynthesis. Primary boost is replacing RuBisCO with the enzyme ECR for better initial CO2 capture.

The milk they produce has a special multilayered milk protein crystal structure that acts as a time release complete food as it's processed, with integrated proteins/lipids/sugars. If this can can be reasonably synthesized, it' s a superfood (crystals have 3 times the caloric content of buffalo milk)
