One of the favourite lessons I've learned from my reading of popular #biology reporting is that there are no provisional or transitional species. Every single population that's ever lived on this planet looked like that because it was pretty good for an ecological niche at that time. Archaeopteryx was not a weird transitional being or a false start. It was an almost perfect archaeopteryx that must be judged on its own merit. There has never been a better archaeopteryx since then.

Tiny plastic bits have made their way into everything from soils to the human brain. A new study has now shown that airborne #microplastics can even penetrate plant leaves.

https://www.quantamagazine.org/the-mysterious-flow-of-fluid-in-the-brain-20250326/ The brain has one of the highest metabolisms of any organ in the body, and that process must yield by-products that need to be removed. But what about that blood brain barrier that likes to micro manage everything. #science #medicine #biology #mystery
If there is a niche, Life will find it.
The famous 'Photo 51' of #DNA using X-ray diffraction by Raymond Gosling & Rosalind Franklin in 1952. The step pattern shows the ladder structure of DNA's base pairs, and the missing "step" suggests the overlapping double strand helix shape.

Demand for tiny plants is driving a poaching crisis in southern Africa, where criminal networks have been digging up these rare finds by the millions. AtlasObscura.com has more from the thinly populated region that ecologists call the Succulent Karoo biome, a desert that is bursting with biodiversity:

Dogs Aid Human ACL Injury Research Advancements
Summary: Recent findings in the Journal of Orthopedic Research highlight dogs' role in advancing human ACL injury treatment. Cornell University researchers discovered a protein, periostin, upregulated in both species' joint fluids, underscoring dogs' value in studying ACL injuries and PTOA.

ELOVL2's Role in Immune Aging and Lipid Metabolism
Summary: A recent study in GeroScience highlights the link between lipid metabolism and immune aging, focusing on ELOVL2's role in diminishing immune function with age. This enzyme's decline disrupts B cell development, stressing the need for strategies to counteract aging effects on immunity.

Pathoblockers are different from #antibiotics - they work specifically to halt the pathogenicity or infectiousness of a microbe.
