“…it would be possible to sculpt the duodenums of various organisms out of molybdenum, but it’s just not been apropos growth medium/zeitgeist for that kind of art thus far…”

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.

gas blurs out.

you fill a glass with carbonated soda, it foams up:
you know that to figure out where the surface of the liquid will be, it's halfway between the top edge of the foam and the bottom: in some ways it's the opposite of what happens with critical opalescence, where the boundary between liquid and ...

(aside: the Goon show and Bobobo-Bo Bo-Bobo evoke similar feelings of bewilderment)

Nighttime picture of a human-established watering hole in the Namib Desert. It's round, apparently concrete, with a small concrete "island" in the center, and there is an owl at the edge, which we see from behind. The owl's wings are folded against its body in a manner that suggests a short jacket; its legs look like the owl is wearing white stockings, and its head is turned to the left; we can see one eye (shining in the watering hole's low light), and a very little bit of its beak.

ok but why does this owl at a watering hole in the Namib desert (which I saw via the watering hole's webcam) look like a little old English lady-owl on an evening walk who kicked off her shoes but left her stockings on to cool her feet in a pond on the outskirts of the village?
