Featured article out today in the New Yorker about a class on existential risks taught at UChicago by the inimitable Daniel Holz (@decohere) and myself this spring: newyorker.com
The @BulletinAtomic Doomsday Clock is at 90 seconds to midnight. In this podcast we discuss why.

An article about the Are We Doomed? class I taught with James Allen Evans. The material seems to be ever more relevant. We’ll be teaching it again Winter quarter, and hope to place all of the material online and freely available. mag.uchicago.edu/science-medici…
Excellent article by @majohnso . Perhaps the first time that scientists worried that their advances could doom humanity. But certainly not the last time. washingtonpost.com/science/2023/0…

The 4th observing run of our gravitational-wave detectors officially starts today!! Stay tuned for lots and lots of black holes. And neutron stars too! @LIGO

Please join us to watch and discuss the movie Fail Safe at the Siskel Center. As the announcement says, “We recognize this is a bummer. Complimentary popcorn will be provided with every ticket purchase—and drink specials will be offered!” siskelfilmcenter.org/fail-safe @BulletinAtomic
Short, powerful video introducing the Pathogens Project conference in Geneva.

A new paper on gravitational lensing of gravitational-wave sources, led by Mesut Caliskan (started while he was a UChicago undergraduate) with @jmezquiagabravo and Otto Hannuksela. It's surprisingly difficult to distinguish lensing and (bad) luck! journals.aps.org/prd/abstract/1…
Achievement unlocked: Finding a typo in one of Bob Wald's equations
The latest issue of the #LIGOMagazine is out! This one includes lots of @LIGO @ego_virgo @KAGRA_PR excitement for O4 (we plan to turn back on in May!). It also includes an article on the collaboration's carbon footprint.

Mike Warren was an amazing friend and collaborator. He was one of a kind. Helped invent beowulf clusters (with numerous Gordon Bell prizes to prove it). Also expert at mountain rescue, bicycle racing, guitar, poker, pool, etc. So many happy memories. losalamosreporter.com/2023/02/23/obi…
Fun, fresh paper led by Reed Essick, asking whether GW sources are random on the sky. Although data is consistent with isotropy, we find an excess in the direction of constellation Equuleus. @GWastrology Note: title is pun intended. tinyurl.com/3huhhnmr @farrwill @mayaKfish
Congratulations to Yiqi Xie on publication of "Breaking bad degeneracies with Love relations". We explore using the neutron star equation-of-state to improve gravitational-wave cosmology. And who can resist a New Mexico-inflected pun? journals.aps.org/prd/abstract/1…
BREAKING: In his annual remarks, UN Secretary-General @antonioguterres said “the Doomsday Clock is a global alarm clock.” thebulletin.org/2023/02/un-sec… (1/n) #DoomsdayClock #UNGeneralAssembly #UNSG @BulletinAtomic @UN @UN_Disarmament
UN Secretary-General @antonioguterres tells us “the Doomsday Clock is a global alarm clock.” and “We need to wake up—and get to work.” We couldn’t have said it better. @francoisdm @BulletinAtomic thebulletin.org/2023/02/un-sec…
The #DoomsdayClock is now at #90SecondsToMidnight. Existential threats, like the possibility of nuclear war, put us all at risk. How do you want to see the world #TurnBackTheClock?
“If there was ever a time for world leaders to take actions to turn back the Clock, it’s now. Until then, it is 90 seconds to midnight.” Op-ed with @JerryBrownGov and @SharonSquassoni on @CNN. @BulletinAtomic @UChicago #DoomsdayClock cnn.com/2023/01/24/opi…
It is 90 seconds to midnight. It is time to turn back the clock. @BulletinAtomic @UChicago npr.org/2023/01/24/115…
This coming Tuesday we announce the setting of the #DoomsdayClock. We are currently at 100 seconds to midnight, the closest we have ever been. Tune in to find out if the @BulletinAtomic believe that humanity is finally able to #turnbacktheclock.
