Coordinated molecular and physiological adaptations enable activity at sub-freezing temperatures in the snow fly Chionea alexandriana Snow flies (Chionea) are small, wingless insects active on snow even at sub-freezing temperatures. Capek et al. combine comparative genomics with experiments to show that endogenous heat production, e...

how does life thrive at sub-freezing temperatures? check out our study on the amazing and elusive snowfly … using comparative genomics we uncover mechanisms that endow the snowfly with the ability to tolerate extreme cold - from antifreeze, to ROS tolerance, to thermogenesis! tinyurl.com/mr2a24ty

On the first day of Christmas (in about 2014), @duckswabber.bsky.social gave to me - a partridge in a pear tree.

Happy Christmas everyone!

so true

Most Nature papers are published in Current Biology

Olfactory floral mimicry of injured ants mediates the attraction of kleptoparasitic fly pollinators Mochizuki reports a plant that lures pollinating flies by imitating the scent of ants injured by predators. This study reveals the first known case of ant mimicry in flowers and uncovers previously un...

Although highly topical, kleptoparasitism does not get nearly the attention it deserves!

Here, a plant exploits the kleptoparasitic behavior of a fly that likes to snatch ants killed by spiders.

🕷️🐜🪰🌿

So the thief itself gets taken advantage of. Nice going, plants!

First ever confirmed image of a colossal squid in the deep ocean The colossal squid is the largest invertebrate on the planet, but it is also surprisingly elusive. An image of a 30-centimetre-long juvenile is our first glimpse of the animal in its natural habitat

A colossal squid — the largest invertebrate in the world — has been photographed alive in its habitat for the first time. And it's just a baby. www.newscientist.com/article/2476...

In our latest paper, we describe how the passing-stripe hunting display of the broadclub cuttlefish camouflages the hunting predator during the final moments of the attack.

Connectome-driven neural inventory of a complete visual system - Nature A connectome of the right optic lobe from a male fruitfly is presented together with an extensive collection of genetic drivers matched to a comprehensive neuron-type catalogue.

I know there's a 𝒍𝒐𝒕 going on right now, but I couldn’t be prouder to share this long-incubated labor of love: the complete connectome of the male 𝐷𝑟𝑜𝑠𝑜𝑝ℎ𝑖𝑙𝑎 optic lobe 🧠🪰

Top left: Cartoon showing how the eye is organized into ommatidia containing nine photoreceptors (left), with distinct ommatidial types typically defined by the opsin expression patterns in the R1 and R2 cells (right). R1/R2 axons bypass the lamina (LA) and project directly to the medulla (ME), while R3-8 project only to the lamina where they can also make inter-photoreceptor synaptic connections with R1/R2 axons. Bottom left: Representative anti-UV1 and anti-UV2 antibody stains in three representative white H. c. alithea males showing consistent expression of UV2 and variable expression of UV1 across individuals. Right: These white Heliconius cydno alithea butterflies are mating on a passionflower vine, but the male had a choice between white and yellow-winged females. Image credit: Wei Lu.

Neural circuits that link genetic variation to #behavior: This study of mate choice behavior in Heliconius cydno #butterflies shows that alterations to the peripheral nervous system, driven by genetic & gene expression differences, can alter essential behaviors 🧪 @plosbiology.org plos.io/4iHQDRd
