Botanists have long speculated about the adaptive value of visitor-triggered stamen movements, and here experiments that compare flowers with and without mobile stamens demonstrate large effects of stamen movements on pollen export, receipt, and nectar costs per pollen transport.

Diversification of human pacemaker subpopulations is directed by WNT and TGFβ signaling.

The first-in-class, humanized, epitope-specific FSH-blocking antibody MS-Hu6 is efficacious, durable, and manufacturable, and is therefore poised for further development towards future testing in human trials for osteoporosis, obesity, dyslipidemia and neurodegeneration.

While perceptual content is encoded in non-oscillatory activity in the slow cortical potential (<5 Hz) range, perceptual stability is predominantly influenced by the amplitude fluctuations of alpha (~10 Hz) and beta (~20 Hz) brain oscillations.

Allorecognition in Neurospora crassa requires CWR-1 (cell wall remodeling protein), an essential process that ensures identity of an interconnected fungal syncytial colony and requires the CWR-1 polysaccharide monooxygenase domain, but not its catalytic activity.

Lactate-Ndrg1a signaling protects the kidney from hypoxic injury and functions partly by inducing reversible degradation of the ATP-demanding sodium-potassium ATPase pump.

Biased growth of microtubules in the advancing axon tip contributes to the uniform orientation of microtubules in mature axons, which is essential for proper neuronal functioning.

In Drosophila, genomic CRISPR/Cas9 expression necessary for CRISPR-based gene drives harbors fitness costs presumably caused by off-target effects, which can be minimized by using a high-fidelity version of Cas9.

A horizontally shared type VI secretion system affects the interaction between vibrios and eukaryotic hosts.

Blood donor serosurveillance in eight of Brazil’s most populous cities reveals extensive variation of SARS-CoV-2 attack rate across cities, age, and sex groups in December 2020 and increased intrinsic severity of the Gamma variant of concern.
