🔴 We have a fun thing for you today in @nature.com - a game! We took the latest research into Mars terraforming and transformed it into an interactive adventure. 🌿 How would you make the red planet green? Try your hand and see if you can win. 🧪 www.nature.com/immersive/d4...

Can you terraform Mars? Try Nature’s game

Once the realm of science fiction, the idea of making Mars habitable is gaining traction. Nature consulted with key scientists to develop this experimental adventure.

I took a break from science policy to step back and write about the beguiling mystery of dark matter and how much we've learned about how little we know. A spoiler: It's a story without an ending. No one's directly detected dark matter yet, and there's no guarantee of when that will happen—or if.

The search for dark matter has been blown wide open

After decades of hunting, physicists still don’t know what makes up most of the universe’s matter. Now they need to cast a wider net.

Today NASA named four skilled astronauts as the #ArtemisIII crew for a test mission in low-Earth orbit, perhaps next year. All four are men, even though NASA has loads of highly qualified women astronauts. It's not a good look for the so-called Artemis generation. 🧪🔭

NASA Marches Toward Artemis III Mission in 2027, Names Crew Members - NASA

Taking another step toward one of the most complex human spaceflight missions in recent history, NASA on Tuesday provided new Artemis III details and

Fun set of science stories. It never occurred to me that headbutting animals could be used for traumatic brain injury research, but of course it makes perfect sense.

Scientists shared their standout days for this @nature.com feature. Thx to @nicoleackermans.com @bwjones.bsky.social @aishikghosh.bsky.social @peixotoraquel.bsky.social & others for their stories! If you have a story, please send it my way for part 2!

Strong policy from arXiv! Hallucinated citation = ban for a year from arXiv, and 'subsequent arXiv submissions must first be accepted at a reputable peer-reviewed venue'. [repost: I incorrectly characterized Dietterich before - he is the vice-president of arXiv's external advisory council].

TThomas Dietterich@tdietterich.bsky.social · 3mo ago

We are implementing a similar policy at @arxiv.bsky.social. If there is incontrovertible evidence of LLM slop in a paper, this means the authors did not take the time to read the LLM output and we can't trust anything else in the paper. Penalty is 1 year ban from arXiv followed by...

ICYMI, this lengthy @sciam.bsky.social Q&A with Breakthrough Prize winner & Physics Nobelist David Gross is worth your time. Gross is using his status as a soapbox to warn of the increasingly dire threat of nuclear annihilation. The Cold War ended, public awareness ebbed, but the arsenals remain.

Now on @sciam.bsky.social: Nuclear war may shatter physicists’ dreams of a final theory, says Breakthrough Prize winner David Gross. It’s not every day an eminent theorist calmly explains why you, me, & everyone we know may perish in thermonuclear flames www.scientificamerican.com/article/huma...
