Schlieren confocal microscopy for phase-relief imaging We demonstrate a simple phase-sensitive microscopic technique capable of imaging the phase gradient of a transparent specimen, based on the Schlieren modulation and confocal laser scanning microscopy ...

Finite capture and the closure of roots of restricted polynomials We study how a countable algebraic root set passes to a fractal connectedness locus. Let $D_n=\{-n+1,-n+2,\ldots,n-1\}$, and let $R_n$ be the set of roots of monic polynomials whose non-leading coeffi...

A tale of two volumes of moduli spaces: Weil-Petersson and Masur-Veech Weil-Petersson and Masur-Veech volumes measure the sizes of moduli spaces of Riemann surfaces equipped with hyperbolic and flat metrics, respectively. Over the past several decades, the computation of...

English translation of Sophie Kowalevski's "On the problem of the rotation of a rigid body about a fixed point" This is an English translation and digitisation of Sophie Kowalevski's (also know as Sofya Kovalevskaya) paper on what is now known as the Kovalevskaya Top. The original paper was written in French an...

RNA-specific local translation is patterned by condensates for multinucleate cell growth - Nature Cell Biology Geisterfer, Jalihal et al. show spatially distinct effects of Whi3 condensates on target translation in Ashbya syncytia. In vitro, translation is enriched at condensate–solute interfaces but repressed...

Condensates are powerful ways to break symmetry and cells do remarkable things with them. Here we show that in a multinucleate fungus, a condensate regulates translation of a cyclin and a formin in distinct locations.

Physical Interactions Shape Collective Thermoregulatory Behavior in Honey Bees Honey bees work together to cool their colony when it gets hot, but how do they decide when to act? We show that physical touching between bees is necessar

I am excited to share more research from my lab! This work, lead by PhD student Casey Lambert, identifies physical interactions as a method of communication to coordinate social behavior in honey bees, published in Behavioral Ecology. Let me tell you about it...

A top-down closeup photo of a pale yellow flower with serrated-tip petals, with the ground and leaves below out of focus. There are two little moths in the flower; the moths have a fuzzy gray thorax, and cream-colored wings with thin bands and edges of deep pink.

These pretty, day-flying moths (Heliolonche pictipennis), only about 1 cm. long, are one of my favorite desert spring insects. The only flowers they visit (desert dandelion, desert chicory, or scale bud) close up at night; the moths sleep inside them, which is scientifically adorable. #BugSky 🌿🐙🌼

A new clue to how the body detects physical force

PIEZO2—unlike PIEZO1—is tethered to the actin cytoskeleton, enabling sensory neurons to detect localized mechanical forces such as light touch.

Findings reported in @nature.com by @ericmulhall.bsky.social from @ardemp.bskyverified.social's lab link nanometer-scale imaging to sensory function.
