Jonathan’s exact age is unknown but is estimated to be ~194 years based on a photo from 1882 depicting him in St. Helena already at adult size. St. Helena’s governor gave Jonathan an official birthday — Dec 4th 1832; Abraham Lincoln, Charles Darwin & Queen Victoria would have all been young then. 🤯👇

Scientists have sequenced the genome & methylome of Jonathan, a 194-yr-old giant tortoise who may be the oldest living terrestrial individual on the planet.

Cartoon by Tom Fishburne on how A.I. is transforming our day-to-day communications. In the left-hand panel, a man sits next to his computer and gestures to a single line of text showing on the screen. He explains to his neighbouring colleague how "A.I. turns this single bullet point into a long email I can pretend I wrote". In the right-hand panel, a woman somewhere else is sitting next to her computer gesturing to a big block of text, explaining to a colleague how "A.I. makes a single bullet point out of this long email I can pretend I read". And so the circle of life continues.

The fab new paper by the Bat1K consortium graces the cover of this week's issue of @nature.com. Congrats to @ariadnamorales.bsky.social @sonjavernes.bsky.social @labdavalos.bsky.social @hillermich.bsky.social @emmateeling.bsky.social @bat1kgenomes.bsky.social & all involved in this landmark work.🦇🧬
The front cover of the 1st October 2026 issue of Nature, capturing an aerial gathering of Natal long-fingered bats (Miniopterus natalensis). Bats are extraordinary creatures — they are the only mammal capable of powered flight, have remarkable disease resistance, use echolocation for navigation, hibernate and have longer than expected healthspans. But our knowledge of bat evolution and their remarkable adaptations is far from complete. In this week’s issue, Emma Teeling, Michael Hiller, Liliana Davalos, Sonja Vernes, David Ray and their Bat1K consortium colleagues present genomes for 103 bat species, representing all 21 bat families.

Created by Elín Hansdóttir, the sculpture emits sounds based on force of the wind, directing attention to the natural phenomena around us.

Visiting Iceland for our 2026 Musicality Genomics meeting. A beautiful sculpture near Harpa Concert Hall (Reykjavík) makes sonic overtones as wind travels through. Intended to depict the shape of light beams reflected through vibrating tuning forks, it also resembles a right-handed double-helix. 🧬🎶😊
A photograph of Himinglæva, a stainless-steel sculpture designed to produce sonic overtones as the wind travels through it. This Aeolian harp is based on a Lissajous figure, representing the shape of light beams reflected through vibrating tuning forks. The sculpture produces diverse sounds based on the force of the wind travelling through it, thereby directing the viewer’s attention to natural phenomena like the air around them. In Norse mythology, sailors who sensed the power of the wind and waves around them assumed that the mythical figure Himinglæva (meaning transparent, shining, and small wave) was embodying the water and propelling their vessels across the ocean. The sculpture was created by Elín Hansdóttir in 2021, and can be found outside the Harpa Concert Hall and Conference Centre in downtown Reykjavík, Iceland.

I was going to use the new Leopardus tilcayo cat discovery as a jumping off point for a thread on challenges & controversies of defining what a species is. But then I got lost in this little floofy guy's eyes & all was forgotten.
This 10-year-old male tiger cat is the first of his species (named Leopardus tilcayo) known to science. He is approximately 18 inches from head to end of body and weighs only 3 pounds, making him smaller than the average domestic cat. While scientists first encountered this cat a decade ago, it took recent advanced genomic analysis to confirm it as a new species. The photograph was taken at the Senda Verde Animal Refuge in Bolivia’s Yungas region, where he currently resides. Credit: Joel Sartore, National Geographic Photo Ark
