In 2019, scientists velcro'd 3D glasses to European common cuttlefish (Sepia officinalis)

They didn't do this just to make them look cool as fuck, but in order to study their vision. Using a 3D theatre made for the cuttlefish, they were able to test if cuttlefish have stereo vision (they do!)

"Ele disse ao ChatGPT que era um incel nazista que queria morrer; em seguida, perguntou quantas pessoas precisaria balear em sua escola para aparecer no noticiário. O ChatGPT o ajudou a escolher a munição, o alvo e o melhor horário para o massacre e, depois, ensinou-o a manusear a arma."

🇭🇺 URGENTE: Primeiro-ministro Viktor Orbán liga para o líder da oposição e reconhece derrota na eleição.

It's not just that Orbán losing inspires hope in other competitive-autocratic countries ruled by right-wing nationalist authoritarians. It's that his loss materially changes things in those other countries, because he's been operating as a headquarters and funding source...

When does the body clock begin to synchronize with local time? New research from Washington University in St. Louis shows that a mother helps to set the biological clock for her babies while they are still in the womb.

The food on Artemis II is surprisingly tasty—but it still won’t be good enough for Mars Future missions will need longer expiration dates and grow-it-yourself options. Luckily, labs around the world are working on these menus—and invited National Geographic inside.

O laboratório faz parte da Rede Space Farming Brasil, que busca desenvolver tecnologias para cultivar alimentos no espaço. Em fevereiro, uma jornalista da NatGeo veio conhecer a gente. O resultado está no terço final da reportagem. www.nationalgeographic.com/science/arti...

Comic by War and Peas. Panel 1: Two green aliens are at a press conference, sitting behind microphones. One alien happily says, "Jesus? We love that guy!" Panel 2: A human reporter with a microphone looks surprised and says, "We’ve been waiting centuries for his second coming." Panel 3: The first alien casually responds, "Really? He comes to us every year." The second alien adds, "We invited him for cookies. What did you do?" The reporter starts to sweat. Panel 4: Both aliens pause, looking inquisitive. One alien asks, "Wait. What did you do?" All reporters sweat.

A Giant Sea Spider (genus Colossendeis), also known as a pycnogonid, found on the deep seafloor at depths between 2,200 and 4,000 meters. 🌊🦀

While some species are small, those in the deep ocean can grow over 50 cm (20 inches) across due to deep-sea gigantism.

Eu vi um vídeo na rede vizinha de uma menina usando um site q replica as informações q a IA do google tem sobre vc a partir das suas fotos. Ela era estadunidense e fez comparações com fotos com roupas diferentes.

Mas essa IA reconhece também local da foto, dai me bateu a ideia de fazer outro teste

screenshot of a post on facebook from Alex Lamoreaux, depicting two versions of the "same" photograph of a bobcat in front of a pine plantation, one labeled original game cam photo, one labeling AI processed

the markings have been altered on the AI photo, and the head changed and resized

text says:

Oh! A neat goose hybrid posted to ‘What’s this Bird?’ but when you zoom in on the photos the bill details have been too manipulated by AI photo editing to be accurately assessed for which species may be involved.
Scroll on… A cool-looking Red-tailed Hawk that someone is wondering which subspecies it might be - right up my alley! But when you zoom in on the photos literally every feather group has been so heavily manipulated and altered by AI editing that it’s impossible to determine subspecies because the photo is essentially fake now; just a mashup of whatever AI thinks parts of a Red-tail should look like. 
Scroll on… WOW! That’s a remarkable trail cam photo of a Bobcat! It almost looks like a painting!… but the head looks oddly small…. hmmmm. After some prodding the original photo is produced and sure enough it had been so heavily altered by AI ‘post processing’ that the photo posted was essentially a digital mock-up with totally different proportions and fur markings. No longer the photo off the trail cam; it may as well have just been ‘created’ by AI from scratch.
This stuff is killing me. My days on social media are becoming very limited. We can’t even trust simple, everyday photos of animals to be real. The wildlife community needs to quit editing with AI, and we need to start calling out photographers that are using it. Our reality is being destroyed all around us.

this field biologist does a great job highlighting the insidiousness of AI editing

these one-click AI edit buttons are incredibly appealing to many photographers, amateurs and professionals alike, and are framed as innocuous

this is worth sharing and educating people about

The ugly history behind the Olympics’ new gender test How Nazi-era fears about gender gave rise to sex testing—and why the policy is resurfacing now.

"These tests that the IOC and a lot of sports federations are now presenting as new technology.

They have literally used these before and found that they were, on one hand, inaccurate in creating these false positives, and on the other hand, just in violation of people’s human rights.”
