SPT/SPT-3G collaboration meeting taking place this week at The University of Chicago! Great to see everyone and having great discussions about all the ongoing science analyses of SPT data! U.S. National Science Foundation DOE Office of Science #Antarctica

On this Independence Day, we celebrate the freedom to innovate, discover, and lead. U.S. Department of Energy’s National Labs are powering America’s future—through science, security, and a competitive edge. #DOENationalLabs

NSF–DOE Vera C. Rubin Observatory, funded by the US National Science Foundation and US Department of Energy's Office of Science, will add an unprecedented amount of cosmological data to the study of the structure and expansion of the universe. symmetrymagazine.org/article/dialin…

A nice writeup of this unfortunate death at the South Pole 25-years ago, before SPT and before the new station thepress.co.nz/nz-news/360743…

It's a couple weeks late, but South Pole recently celebrated mid-winter at the #southpole. Mid-winter is a big milestone for the winterovers, who are spending a year at the South Pole. Attached is the official mid-winter photo, and dinner announcement from this season!

The SPT winterovers recently hosted an open house and tour of the telescope. Since SPT is 1-km from station, many winterovers don't make it out often, so it's nice to have open houses to help learn about the science they are supporting!

IceCube (IceCube Neutrino Observatory) finds no neutrinos above 10 PeV in 12.6 yrs of data • In 2.9σ tension with the ~200 PeV KM3NeT neutrino event • Disfavors the proton-only hypothesis for ultrahigh-energy cosmic rays PRL: go.aps.org/40mhziS PhysMag: go.aps.org/4lOm6mg

NASA Watch European Space Agency NASA mj The US has more people spending time in the exact same environment year round. There is an excellent opportunity for NASA to be doing more.

New SPT-3G constraints on early dark energy: "combining with DESI ... we get fEDE=0.071+0.035−0.038 at 68% CL and a weak preference for AEDE over ΛCDM. this shift is a manifestation of the discrepancy present between DESI and CMB experiments in ΛCDM" arxiv.org/abs/2507.23355
