Who knew?

I’m happy to announce the release of a new open source 3D physics engine called Box3D. I’ve been working on this project for a few years now, but it represents over 20 years of experience writing physics engines for games. Read more here: box2d.org/posts/2026/0...

NEW BLOG FOR YOU Google's energy consumption numbers in their new climate report are mind-blowing. 2 years ago they flipped from linear to exponential growth, and their climate impact is blowing out, too. A WILD testament to the obscene bloat and waste of GenAI: ketanjoshi.co/2026/07/01/g...

I welcome a fact check, but Spain, a nation of 50 million people, accomplished the bulk of this transition in about 6 years I believe. And that’s *without* the great new batteries.

The Lebanese Government Has Handed Over The Following Villages To Israel Under Its Normalisation Agreement Lebanese citizens can no longer return to their homes & are experiencing a Nakba like event if they are from: •Al-Bayyada •Shemaa •Majdal Zoun •Al-Mansouri •Naqoura •Alma Al-Shaab 1/4

This should be good!

"Israeli forces stormed a wedding in Anata, east of occupied Jerusalem, firing tear gas heavily and causing civilians to suffer from tear gas inhalation."

would be simply absurd, except it is, as usual, malicious (the Indian Ministry of External Affairs has claimed that the Indian passport is not proof of Indian citizenship, but merely a travel document) scroll.in/latest/10938...

Yes! I was really heartened by @neilshubin.bsky.social’s election and was hoping it would represent a much-needed sea change. Scientific organizations are a powerful force for the public good, if they exercise that power.

Update: The National Assembly president put the latest toll at 188 dead, 1,520 injured and 157 reported missing. He said teams are racing to rescue hundreds of people still trapped in damaged buildings.

Incredible example of how nonsense Hindutva history is established and even monumentalized in the west, depending on ignorance, indifference and vague protestations of anti-colonialism to do so. Read the whole thread and weep @rcsed.bsky.social

The British Medical Association (BMA) has voted to drop the controversial International Holocaust Remembrance Alliance (IHRA) definition of antisemitism, saying it had a “chilling effect” on free speech in the workplace.

This is why cities need trees. Hard surfaces and parked cars can reach extreme temperatures, while shaded grass and tree-covered areas stay dramatically cooler. This is the urban heat island effect in one image: hard surfaces absorb and radiate heat, while vegetation and shade reduce it.

how extreme is the heat in Europe? double decker buses in London are *spontaneously combusting* phenomenalworld.org/analysis/glo...

Jesus EQ death toll in Venezuela could surpass 10,000 This requires an intenrational response. No country can handle destruction of this magnitude , least of all a country in such dire straits already as Venezuela.

An associate editor for Frontiers in Systems Neuroscience has resigned. He asked the editorial office to turn off the AI assistant, and was told it was "not possible". 😵 Read the whole thread!

Okay. Ai can go bankrupt then. This is not our problem, this sounds like a rich tech billionaire problem.

We regret that our event on Extreme Heat: Improving governance and strengthening action around the world has been cancelled due to the red extreme heat warning issued by the UK Met Office. Our apologies to everyone who was planning to attend the event.

Free speech and dissent have been criminalized. This is not "going to happen" this is "already happened and people went to jail for it." Pay attention. Make plans. This is already a war it's just that only one side is fighting right now and it's not our side.

A cartoonist named Daniel "Des" Rolando Sanchez Estrada was tried as a terrorist and sentenced to 30 years in prison for having anti-Trump comics in his car. Prosecutors connected him to a 2025 anti-ICE protest he didn't even attend because he was in the same book club as others who were.

Worse. It’s a literal plagiarized butthole.

"We should call this action what it is – blatant union-busting...we also have reason to believe that the sale was motivated by fear within Springer Nature that our attempts to doggedly report on the crisis facing science in America today would lead to repercussions from the Trump administration."

When reality surpasses fiction! Top: fictional forecast for August 2050, broadcast by French TV in 2014 to warn about the consequences of global warming. Bottom: Real French forecast for yesterday, June 22, 2026.

The sentences handed down today in Texas are a threat to the possibility of a democratic society. The prosecution is rife with constitutional violations, but 30 years in prison (more than anyone for January 6) for moving some magazines? 50 years for those not involved in even planning the protest?

(also, the piece I complained about being taken down at SA...was not even mine! they published it for a WEEK before they took it down!) appease the fascists, and they'll take your head, too, eventually—only after you have debased yourself and your mission! theintercept.com/2021/07/01/s...

I have a hard time being sad about Scientific American layoffs bc when I complained abt SA pulling a piece about Gaza (in 2021!!!) they stopped commissioning me & it only goes to show you that if you capitulate & don't hold the line, you, too, will get chucked one day, no matter how cowardly you act

Today is my last day at Scientific American, which has been sold to LabX media group. For three decades I've led the magazine's coverage of human origins, archaeology, paleontology, animal behavior, ecology, BIRDS. End of an era. Anyway this feels weird to say, but I'm now available for assignments!

I am thrilled that my dream project was funded by the #ERC @erc.europa.eu as a 5 year Advanced Grant! Final amount somewhere over €2M. I'll be advertising 2 postdocs (1 more empirical; one more theoretical), technician and research administrator in due time. erc.europa.eu/news-events/...

Scientific American is being sold to LabX Media, publisher of Discover: group.springernature.com/gp/group/med... They've fired me and other union staff, ahead of June 26 vote ratification. My rates are suddenly more reasonable, if you need editing or reporting - [email protected]

Dan is my husband, as well as a phenomenal science reporter and editor with experience at not just SciAm but NatGeo, USAT, BuzzFeed, and Science News, too (and has a background in aerospace engineering to boot). You should definitely hire him. I don't know anyone who hustles more to get a story.

Wow. Prairieland defendants being handed sentences between 40 and 100 years. For background on this case: www.ms.now/news/antifa-...

With effective life sentences of protestors for... not actually doing anything but being at a protest where someone else fired a gun, Americans should be aware that we no longer have a right to protest. The government will imprison us if they don't like the protest and can find a pretext.

Texas and Florida may have passed it by now, but Indiana was an early leader in dismantling academic freedom in its university system, and it certainly hasn't gotten any *better* just because other states have gotten worse.

Today was an absolute blood bath at SCOTUS for the less powerful to enforce civil rights in the federal courts. TL;dr - SCOTUS rules 6-3 that only corporations have rights that are enforceable in federal court??

Britain about to get its seventh Prime Minister in ten years. I can’t say I’m surprised. As a people they’re often wonderful of course—very musical, for example, many charming customs, and always joking around in their quirky way—but they just don’t have the temperament for stable self-government.

Very excited to share our discovery of an engineering masterpiece from the Australian rainforest! In our latest paper in @currentbiology.bsky.social we report a hunting strategy in a spider, whose web outperforms every known biological catapult system.

My friend's NSF CAREER received the highest possible score (Excellent, Excellent, Excellent: High Priority) and it was rejected today. This would have been my friend's first extramural award, 5 years after starting their lab, exactly when grant $ is make or break for an Assistant Professor's career.

tech capture of the NSF: “it allows NSF to make awards to nontraditional recipients such as a limited partnership or a venture capital firm, some of which might have been created solely for the purpose of receiving the NSF award.”

Yeah, fuck this. Our public money is essentially being diverted from science to supporting the stock prices of ruling party donors.
