I too think the same way. I purposely stay away from all due to excessive doom and gloom. However I haven’t really found any topic specific instance where I would enjoy local content. Now I think finding interesting topic specific instances is a problem whose solution I haven’t found yet. Communities I can find using search function; I even created an account on lemmy world simply to find obscure communities I would be interested in. I wish there would be a simple search function to find topic specific instances.
Couple of times I have come across a cat sitting and intently looking into a closed manhole (probably in hunting mode waiting for rats) and they completely ignore me when I meow at them! Lol.
Obviously this is just in initial research phase, very far from being unleashed on nature. It would be interesting to see how this research progresses.

Synthesis of sustainable sulfur-containing polycarbonates from xylose and carbonyl sulfide - SFFA
Abstract Herein, the six-membered sulfur-containing cyclic carbonates was
successfully synthesized from d- and l-xylose through an environmental friendly
process by employing carbonyl sulfide (COS) as a sustainable C1-carbonation
agent. The ring-opening polymerization of the monomers were rapidly initiated by
bifunctional organocatalysts and alkali metal alkoxides, respectively, under
ambient reaction conditions. The resultant sulfur-containing polycarbonates
exhibit high-temperature resistance and good optical properties. This work
furnishes an original and practical strategy for utilizing COS as a sulfur
feedstock in biopolymer synthesis.

Genetically modified bacteria may eat up ocean plastic waste - SFFA
The research team conducted experiments involving two bacterial species: Vibrio
natriegens and Ideonella sakaiensis. Vibrio natriegens primarily inhabits
saltwater ecosystems and is notable for its rapid reproduction rate. On the
other hand, Ideonella sakaiensis possesses enzymes that give it the power to
break down as well as ingest PET quickly, distinct from its. As a result, the
researchers isolated the genetic sequence from the latter (Ideonella sakaiensis)
and integrated it into a plasmid. Plasmids are genetic sequences that may
replicate independently within a cell even when it is distinct from the cell’s
original chromosome. “In other words, you can sneak a plasmid into a foreign
cell, and that cell will carry out the instructions in the plasmid’s DNA. And
that’s exactly what the researchers did here,” noted the release. The scientists
then carefully incorporated the plasmid containing Ideonella sakaiensis genes
into Vibrio natriegens bacterium in the lab. The resultant, V. natriegens was
able to produce the required enzymes on its cell surface. The researchers
demonstrated that V. natriegens could degrade PET in a room-temperature-based
saltwater setting. “From a practical standpoint, this is also the first
genetically engineered organism that we know capable of breaking down PET
microplastics in saltwater. That’s important because it is not economically
feasible to remove plastics from the ocean and rinse high concentration salts
off before beginning any processes related to breaking the plastic down,” said
Tianyu Li, the first author of this new study

Low-emissions strategy that could pay for itself helps scientists achieve
high-yield hydrogen gas and high-value graphene.
That makes sense. For me, I am very sure about what topics/communities I am interested in; other things I am not interested in checking out. My subscribed field takes up the time I allocate to lemmy anyway.
I never browsed all on reddit all the years I was on it.
As a a casual lemmy user with accounts on a few instances, I can say that I never visit the local or all fields of any of my logged in instances. I only visit my subscribed field, which is identical over all my accounts. How much do the local and all fields really matter for users?
I could never say no to that face 🥰 The ears are very impressive.
