I'm excited to introduce Mark 1, Until's electromagnet for rapidly rewarming organs from cryogenic storage temperatures. We set out to scale magnetic nanoparticle warming to human-scale organs while keeping the coil losses low enough for hospital use. Mark 1 produces a 900 kHz oscillating field at up to 40 kA/m with 7 kW of coil loss in a bore compatible with human-sized organs. This intersection of field, frequency, coil volume, and efficiency makes the system a first of its kind.
For organ rewarming, we reduce the field strength to 29 kA/m and bring the losses down below 4 kW. At these settings, we have been able to rewarm a vitrified pig kidney loaded with our in-house nanoparticles at 50 C°/min while consuming a total of less than 4 kW out of the wall. At this power, the device could run off of a common single phase 208V circuit. This 50 C°/min warming rate exceeds the critical warming rate required to outrun ice formation using our in-house cryoprotectant.
Mark 1 is just one example of the significance of audacious engineers and applied physicists for progress in reversible cryopreservation. If you're excited by pushing the frontier in hardware to improve human health, join our team.

Despite fighting malfunctioning equipment, I captured one of my most surreal videos ever.
That’s the moon crossing in front of the sun. You can see mountains on the lunar limb as it transits the chromosphere.

This should be a bigger story.
Scientists are more concerned than ever that a critical Atlantic current will collapse soon and wreak havoc on North America and Europe. The Atlantic Meridional Overturning Circulation, or AMOC, is a massive conveyor belt of ocean currents that transports water from the tropics to the Atlantic.
Without it, severe weather would impact both regions at potentially devastating rates.
These scientists aren't just warning us about an environmental issue—they're sounding the alarm about a climate threat that could fundamentally rewrite how future generations survive on our planet.

draggable stickers on a website for an event @purduehackers is hosting
the stickers share data across clients so when someone moves a sticker, it moves on your screen too :3

pure. wholesome. the funny little man sees that the other freak is moving, sees it might be alive. conscious. and examines him respectfully. no harm, no foul. precious animal. respectful animal. no reason to turn him into stew. will look into this

Scientists identified ribose (used in RNA) and – for the first time in any extraterrestrial sample – glucose, a major energy source for life. These sugars join nucleobases and phosphates previously found, demonstrating the full suite of RNA building blocks were present on the ancient asteroid.
ALT This image shows a circular metal container divided into six wedge-shaped sections, each filled with varying amounts of dark, fine-grained material and small rocks. The surface is highly organized, with scientific tools and utensils placed neatly to the left and right sides. This container holds samples collected from asteroid Bennu by NASA’s OSIRIS-REx mission, prepared for analysis in a sterile laboratory environment.

i'm running the largest creative-technical demo day in the midwest... out of a coffee shop!! :)
this saturday @purduehackers is hosting spill ≋, the second in our series of pop-up demo days where our members get to showcase various projects they've been working on throughout the semester! we have so many cool things folks have built, including:
- a restored industrial robot arm that was once a welder, but now plays connect 4 with you 🏗️
- a cpu with brainfuck, the infamous turing complete language, as its native instruction set, running at billions of cycles 🧠
- a projector butterfly garden that lets you draw your own butterfly and see it spring to life in a virtual simulation you can control with your hands and body 🦋
- a custom-built robot, cv pipeline, and virtual instruction set capable of performing computational operations on a rubiks cube 🧊
and so many more wacky, wild, and fascinating projects created by super talented individuals. all displayed in one night, over the course of three hours.

Slack is threatening to shut off a big nonprofit teen coding community @hackclub (which is amazing and which I’ve helped for years) with just 3 days to migrate off. This would strand thousands of of the world’s smartest future coders. They are asking for $50k (a surprise 60x nonprofit price increase) but won’t even give assurances of more time or future service if that’s paid.
Anyone who can help? Feels like a mistaken decision on their part by someone who isn’t seeing the whole picture.

@cradle_health We're building a pause button for biology.
If you want to join an early team working on some of the hardest problems in biology and engineering, I think you'll fit right in

i love the "never kill yourself" genre bc it captures the slippery truth that the distance between a life worth living and wanting to die really is, like, one minor amusement a day
that's why it's imperative to go outside and look at things and try to like them

Microplastics? No no no, it's micro pig kidney, processed with micro dicer and micro grater made with DRIE (Bosch process).
Stuff like this really makes me wonder how many interesting things are waiting to be done across multiple research fields.

The Polaris Dawn crew will wear smart contact lenses in space to monitor their intraocular pressure, in efforts to learn more about Spaceflight Associated Neuroocular Syndrome, or SANS, as part of a University of Colorado Boulder research experiment.
This is just one of 36 science and research experiments from 31 partner institutions flying with the Polaris Dawn crew. Learn all about them here → polarisprogram.com/science-r…
The crew has put extensive time and effort into ensuring the mission will help expand our knowledge of human health in space.
A few months ago, teams released a significant amount of findings from similar projects conducted during the Inspiration4 mission: nature.com/immersive/d42859-…
"The Space Omics and Medical Atlas (SOMA) package of manuscripts, data, protocols, and code represents the largest-ever compendium of data for aerospace medicine and space biology. Over 100 institutions from >25 countries worked together for a coordinated 2024 release of molecular, cellular, physiological, phenotypic, and spaceflight data."
I expect to see similarly impactful data from the Polaris Dawn mission and future Polaris Program missions!

Such a cool and complex photo to set up. The sunlight in our eyes was impossibly bright as we waited for Sergei Avdeev to take a series of photos from his bedroom window on space station Mir. Then we retrieved the film from him and returned it to Earth. Glad this one turned out so well - an amazing, cooperative moment in time and space.
