An ATLAS 240 GeV Higgs-Like Fluctuation Meets Predictions From Independent Researcher

A new analysis by the ATLAS collaboration, based of the data collected in 13 TeV proton-proton collisions delivered by the LHC in 2016, finds an excess of X-->4 lepton events at a mass of 240 GeV, with a local significance of 3.6 standard deviations.

Cassini provides a magnetic mystery

Saturn's magnetic field has no discernible tilt relative to the planet's rotational axis, according to data from NASA's Cassini spacecraft. This unexpected result means the exact length of a day on the planet is still unknown.
Cassini is currently undergoing its Grand Finale phase – 22 weekly orbits of Saturn that take the spacecraft between the planet and its rings. This stage of the Cassini's mission began on 26 April and it has completed 14 of the orbits. After 22, Cassini will perform its final act and plummet into the planet's atmosphere on September 15.

Proton–proton collisions prove stranger than expected

By the time the universe was picoseconds old, the four fundamental interactions—strong, weak, electromagnetic, and gravitational—had become distinct from one another. Yet, for another few microseconds, the universe remained too hot to bind quarks into protons, neutrons, and other hadrons. Instead, quarks and gluons, the bosons carrying the strong force, existed as a hot, dense soup called quark–gluon plasma.

A Smooth Exit from Eternal Inflation

S. W. Hawking, Thomas Hertog
(Submitted on 24 Jul 2017)
The usual theory of inflation breaks down in eternal inflation. We derive a dual description of eternal inflation in terms of a deformed IR CFT located at the threshold of eternal inflation. The partition function gives the amplitude of different geometries of the threshold surface in the Hartle-Hawking state. Its local and global behavior in dual toy models shows that the amplitude is low for surfaces which are not nearly conformal to the round three-sphere, and essentially zero for surfaces with negative curvature. Based on this we conjecture that the exit from eternal inflation does not produce an infinite fractal-like multiverse, but is finite and reasonably smooth.

Spinning black holes could grow long hair

A potentially explosive phenomenon called superradiance could give black holes hair – according to William East of the Perimeter Institute for Theoretical Physics in Canada and Frans Pretorius of Princeton University in the US. Their claim relies on the existence of an extremely light particle and could be confirmed by detecting gravitational waves associated with the hair.
