woah this is genuinely, utterly WILD
Ant queens of one species produce males of another species, so she can then mate with them and produce hybrid workers!
This is so gloriously weird I can't quite compute it 🤯🧪🐜

‘Almost unimaginable’: these ants are different species but share a mother
Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

I am cracking up... doing a literature search on eDNA and this came up:
"The platypus: evolutionary history, biology, and an uncertain future."
I’m sure it’s a great paper—but how it snuck into my search results without having any of the keywords is an evolutionary mystery of its own. 🦆🦫🔍

Grateful to Nature editors and scientists and others around the world for their support.
They understand that despite the ongoing nationalist rhetoric around this, scientific progress is not a zero-sum game.

Trump 2.0: an assault on science anywhere is an assault on science everywhere
US President Donald Trump is taking a wrecking ball to science and to international institutions. The global research community must take a stand against these attacks.

It is disturbing how the Trump regime is silencing and crippling science. We had a paleontology online seminar scheduled next week on Permian fossils and environments in Grand Canyon - but the US colleague planning to present has suddenly been sacked.

From the recent field survey for the TWINKLE project, eDNA sampling along Ionian and Cretan Seas. We aim to discover the mesopelagic biodiversity.

#COP29 fails to make anything substantial.
Government officials are continuing to brake any trust that might have been left, leaving great gaps in policy and finance.
We shall keep working towards a better future.
