Helium powered stellar blast may leave a...
section5:
The first so-called helium nova, the possible result of a large white dwarf sucking material from a hydrogen-deficient companion star, may be a precursor to a supernova.
A stellar explosion known as a nova that was detected in 2000 formed a two-lobed shell of material ejected from the star. Shaped like a bow tie, it continues to swell at great velocity. But, curiously, the coat of...
New theory of Quantum Gravity →

which splits time from space at high temperatures. I’m always up for a new model of reality.

Nucleation
cloois:
Phase transformation generally begins with nucleation, in which a small aggregate of atoms organizes into a different structural symmetry. The thermodynamic driving forces and kinetic rates have been predicted by classical nucleation theory, but observation of nanometer-scale nuclei has not been possible, except on exposed surfaces. We used a statistical technique called fluctuation...

LHC to Finally Start Next Week, Again →
CERN is reporting that the Large Hadron Collider could circulate particle beams through both of its pipes in just over a week. If all goes well, the first collisions would begin soon after that.

Signature Of Antimatter Detected In Lightning
roomthily:
During two recent lightning storms, Fermi recorded gamma-ray emissions of a particular energy that could have been produced only by the decay of energetic positrons, the antimatter equivalent of electrons. The observations are the first of their kind for lightning storms. Michael Briggs of the University of Alabama in Huntsville announced the puzzling findings November 5 at the 2009...
