Researcher proposes model replacing dark energy/matter to explain universe (phys.org)
Dr. Richard Lieu, a physics professor at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a paper in the journal Classical and Quantum Gravity that proposes a universe built on steps of multiple singularities rather than the Big Bang alone to account for the expansion of the cosmos.

The Crisis in String Theory Is Worse Than You Think (math.columbia.edu)
Curt Jaimungal has a piece out, an interview with Lenny Susskind, with the title The Crisis in String Theory is Worse Than You Think…. Some of what Susskind has to say is the same as in his recent podcast with Lawrence Krauss (discussed here). These days, Susskind sometimes sounds like Peter Woit:
