Volvo posted a 3 min and 46 second ad on Instagram, shot by Hoyte Van Hoytema, the cinematographer of Interstellar and Oppenheimer.

It goes against every single rule you can think about as a social lead. Length. Format. Over-produced.

Every comment under the ad said it immediately put Volvo in their consideration set. It's fucking fantastic.

Here's a photo from ~1995-97 showing hundreds of sectional pieces of what would become the Beam Tube Enclosure for @LIGOWA. The Beam Tube Enclosure houses the 4km Beam Tube for the X & Y arms.

[South Pole Telescope @SPTelescope]

New SPT-3G result! From CMB polarization alone we reconstruct the CMB lensing and an unlensed E-mode power spectrum. We find H0 = 66.8 ± 0.8 km/s/Mpc, in 5.4-sig tension w/ SH0ES, and mnu <0.075eV (95% CL), w/ weak (<3-sig) preference of excess lensing. https://t.co/SPNG8tMmxx

This will actually be really useful and convenient for me (and the rest of Las Vegas)!

[Secretary Pete Buttigieg @SecretaryPete]

Good news, Las Vegas! We just started construction on a new rapid bus line, which is going to save residents money and time, and lead to cleaner air.
