A conserved Bach current

The Bach tensor and a vector which generates conformal symmetries allow a conserved 4-current to be defined. The Bach 4-current gives rise to a quasilocal 2-surface expression for power per luminosity distance in the Vaidya exterior of collapsing fluid interiors. This is interpreted in terms of entropy generation. PACS numbers: 0420J, 0440N

Diabetes--big problem, little confidence.

Little Supersymmetry and the Supersymmetric Little Hierarchy Problem

The current experimental lower bound on the Higgs mass significantly restricts the allowed parameter space in most realistic supersymmetric models, with the consequence that these models exhibit significant fine-tuning. We propose a solution to this ‘supersymmetric little hierarchy problem’. We consider scenarios where the stop masses are relatively heavy in the 500 GeV to a TeV range. Radiativ...

Sarcospan, a little protein for a big problem

Sometimes you can get to your destination just by following the crowd. Baker et al. report that photoreceptor proteins lacking targeting sequences end up in the right place thanks to their more abundant, and more goal-oriented, fellow travelers. Rod and cone cells are divided into four compartments: a synaptic terminal, a nuclear region, an inner segment for protein and lipid synthesis, and an ...
