I know, I know. I just reposted cool UA bio research AND a review of a Norwegian hot dog. I know. I contain multitudes.

Leaving Oslo today and I was finally able to find a hot dog on lefse (potato flatbread) with shrimp salad and crispy onions for breakfast at the airport.
Verdict: delicious

Our paper describing our antimicrobial, which can kill MRSA within mature biofilms, was just accepted. I look forward to sharing it with you.

On Sept. 23, NASA’s OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification, and Security – Apophis Explorer) spacecraft flew within 2,136 miles (3,438 kilometers) of Earth. Video and details: go.nasa.gov/4ofmdIw (Let's hope they don't cancel this mission.)

There were also some excellent Earth as an exoplanet observations conducted. Stay tuned for those.

Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪

Congrats to HiRISE and MRO for doing it again!
This is an OUTRAGEOUS image because it involves taking a spacecraft designed to roll 20˚ side-to-side but mostly point down, and having it pop a wheelie to point the camera away from the planet... (🧵) #PlanetSci 🧪

For anyone wondering why the HiRISE image of 3I/ATLAS only had an exposure time of a few seconds:
HiRISE uses a pushbroom imager with fast readout to avoid blurring images of Mars. To make this image, MRO had to be rolled around in a very unusual sequence.

Here’s an annotated version of our comet image.
We also want to thank our downlink and uplink teams who spent a huge amount of time working on this. Our camera was not designed to image interstellar objects 19 million miles away, but their hard work and planning paid off.

During the U.S. government shutdown, several NASA missions observed interstellar comet 3I/ATLAS as it passed by Mars. Check out some of their amazing images, including this one from the Mars Reconnaissance Orbiter! 🧪🔭☄️

Lots of people thought of doing this, including me back on the day the comet was announced. Crazy fun to see the image now.
