Don’t miss this paper by @jrozasub.bsky.social group, with interesting findings on genome size evolution on a 🕷️’s radiation on oceanic 🏝️
Moreover, they present the complete genome of Dysdera catalonica included in the @catbiogenoma.bsky.social

A third paper comes out. I want to stress that sequencing and annnotating the complete genome of the Balearic shearwater, under the umbrella of the @catbiogenoma.bsky.social, has been key to develope this work. Showing how the efforts of the @ebpgenome.bsky.social will help biodiversity conservation

Four ways COVID changed virology: lessons from the most sequenced virus of all time After 150,000 articles and 17 million genome sequences, what has science taught us about SARS-CoV-2?

In five years, SARS-CoV-2 became one of the most closely examined viruses on the planet. A feature in Nature outlines four lessons from the pandemic that some say could empower the global response to future pandemics. 🧪

Woodlice take care of their babies until they mature. Here a protective parent rests a flagellum on a baby. #Crustmas

A macro photo close on the face of a very hairy, orange-brown spider. It's resting on yellowish dried dirt from a termite mound. The spider has a walrus-mustache look to it. Four of its eyes are forward facing.

I found this hirsute spider hunting on a termite mound at night. Looked a bit like a wolf spider from a distance, but guessing it's in the family Trechaleidae or Ctenidae, based on the eye pattern.
