@deepanshigahlot.bsky.social, @jesucastin.bsky.social, @lipithukral.bsky.social and colleagues identify a lipid-triggered allosteric site in LC3 that remodels its receptor binding interface upon membrane interaction

A programmable lipid-triggered allosteric site modulates LC3 LIR receptor binding activity - Nature Communications
The allosteric mechanisms by which lipid binding controls protein activity remain poorly understood. Here, the authors identify a lipid-triggered allosteric site in LC3 that remodels its receptor-binding interface upon membrane interaction. This site can be engineered to precisely tune LC3-LIR interactions, offering a new strategy to regulate selective autophagy.

A paper in Nature Communications suggests that sustained visceral fat loss, rather than weight loss, is linked to better cognition and attenuation of brain atrophy years later, mainly via improved glycaemic control. go.nature.com/43nvaY6 🧪
This is figure 2, which shows visceral Adipose Tissue (VAT) × Brain Volume Interactions and Cumulative VAT Exposure (AUC) in Relation to Cognitive Function (MoCA).

A paper in Nature Metabolism describes a sensory circuit involving the medial septum (MS), where MS glutamatergic neurons integrate food odours to prime satiety and regulate nutrient intake. go.nature.com/404U917 🧪
This is figure 1, which shows functional mapping of brain regions activated by food odours.

Types of aging paper
wear and tear is bad
the thing we measured is correlated with aging
so-called magic pill has no effect
longest lived mutant yet!
all previous aging theories are fatally flawed
this organelle holds the secret
this harmful thing is good at low dose
our underpowered study suggests this miracle diet slows aging
a long-lived critter does it differently
a multi-omics atlas of the epigenetic aging landscape
you must study the mortality plateau
it is all physics you fools!
