Computational analyses of in-vivo cerebral activity show that gamma oscillations in the olfactory cortex originate from local feedback inhibition following each sniff and serve to segregate competing odor representations through a winner-take-all process, providing an optimal window to decode odor.

A pronounced and consistent healthy vaccinee effect has been identified in rigorously conducted vaccine effectiveness studies, specifically within the first 6 months post-vaccination and among older or clinically vulnerable individuals, likely driven by lower vaccination rates among severely ill populations.
HNF1A, a risk factor gene for pancreatic ductal adenocarcinoma, is critical to maintaining pancreatic cancer stem cell properties through regulating POU5F1 (OCT4) expression, providing a novel role for HNF1A in maintenance of the disease.
By using a specialized camera that corrects for eye blur, millions of single-blood-cells are imaged, and their speed measured, as they travel through the largest-to-smallest vessels of the retina.

Heterochromatin spreading in fission yeast predominantly produces intergenerationally unstable outcomes, requiring an accessory element that represses histone turnover.
The local PI(4,5)P2 nanodomain promotes the dimerization and activation of EGFR in the plasma membrane, whereas activated EGFR dissolves the nanodomain structure of PI(4,5)P2 through PLCγ.

The Bipolar Assembly domain of kinesin-5 comprises an anti-parallel four-helix bundle, which explains how kinesin-5 subunits assemble into bipolar tetramers with two motile ends that transmit forces while crosslinking and sliding adjacent microtubules during mitosis.
Immune cell motility and vascular response are imaged in vivo and label free in the CNS for the first time, using high-resolution phase-contrast adaptive optics retinal imaging.
Crystal structures provide structural rationales for the transport stoichiometry of the gastric proton pump, which suffices the energy requirement for the generation of a million-fold proton gradient across the membrane.
