In the century leading up to 1975, nearly 6000 freighters went down in the Great Lakes.

The Edmund Fitzgerald was the last.

The last. In 50 years, not a single commercial freighter has been lost in the Great Lakes.

Why?

It's NOAA. Of course it's NOAA.

Tornadoes have mostly calmed down over the last month or so here in Italy, but today a waterspout, part of a family of three, managed to reach land W of Salerno, Campania. Damage very unlikely. Photos by Carlo de Felice

Really worth reading the entire 60 minutes interview transcript but admit this part got me laughing out loud.

The night is young yet…

A line of purple and green aurora can be seen behind some clouds with the Big Dipper hovering above

Some green aurora and clouds can be seen over the water with city lights in the distance

It is definitely aurora season

New Moon Discovered Orbiting Uranus

Researchers, including Dr. Mark Showalter and Dr. Matthew Tiscareno of the SETI Institute, along with colleagues at the Space Telescope Science Institute (STScI), discovered a previously unknown moon of Uranus using the James Webb Space Telescope (JWST). 🧪 🔭

Keep sciencing. We are living through a time when looking at a rock and wondering how old it is qualifies as an act of resistance.

This proposed budget is a policy statement, not an appropriation.
There are still a lot of steps and potential changes ahead before it becomes one. This is not a time to sit quietly, team. Let's go.

The standard model assumes neutrinos have zero mass but they have been known to oscillate between three flavors, which only happens if they do have mass.

Vera Rubin has been selected to be featured on the back of a quarter. She is the first astronomer to be honored this way. Read about her research on the Andromeda galaxy and how it led to the discovery of dark matter in this article written by Rubin herself. doi.org/10.1063/1.24...

We are experiencing an assault on science unparalleled by anything I’ve seen in my life. It’s not one issue or another anymore, the entire institution is under attack by the most powerful individuals in the country.

This Friday, where will you be?

This is an attack on US science. NSF staff provide critical support for scientific infrastructure and global excellence. These are valuable dedicated public servants. Please contact your reps, write letters, make noise!

Are there any plans for rallies at NSF headquarters?

Journalists: COVER THIS!

It sounds like they may not be aware of your work. Time to take them up on their “comments welcome”?

looking back, AOL had it right. 30 hours of internet per month was the right amount.

People may not understand just how important federal science research funding is to the prosperity of the nation. I tried to explain it, because it's under unprecedented and direct assault.

Lunar Mare Volcanism: Where Did the Magmas Come From? | Elements | GeoScienceWorld Abstract. The first rocks to be returned from the Moon by the Apollo 11 astronauts were basalts from the mare basins. Analysis of these rocks led to the

Yes, it was an Elements paper led by the great Tim Grove (pdf available via google with original sources cited) pubs.geoscienceworld.org/msa/elements...

My recollection is that mare basalts have a europium anomaly complimentary to anorthosites even though their sources were not plagioclase-saturated implying that the crystal separation was earlier, presumably in a magma ocean. I am not aware of any rebuttal to this argument.

I didn’t know if it might help to actually see what we are talking about with indirect costs so I did a little lab tour.

Some folks have asked, given recent news, “how do I show my friends/family the impact of NSF?” We have some easy Fact Sheets for you! Here’s a brief thread about this website: new.nsf.gov/about/fact-s... which hosts a ton of useful one-pagers.

"When you get right down to it, everybody's having a perfectly lousy time of it, and I mean everyone. And the hell of it is, nothing seems to help much.” ― Kurt Vonnegut

Was at an event in DC this evening with a lot of federal employees and it is absolutely wrenching to talk to people who dedicated themselves to public service work through the appalling attacks and uncertainty that they are facing now.

Happy Isotope Day everyone! 🥳On this day in 1913 Nature published Federick Soddy's paper "Intra-atomic Charge" www.nature.com/articles/092... in which he introduced the term "isotope" (coined after a dinner conversation in Glasgow with Margaret Todd the classics scholar). how will you celebrate?🧪⚒️🌊
