Tests of quantum gravity from observations of γ-ray bursts
The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. Here
Learning and memory deficits upon TAU accumulation in Drosophila mushroom body neurons.
Mutations in the neuronal-specific microtubule-binding protein TAU are associated with several dementias and neurodegenerative diseases. However, the effects of elevated TAU accumulation on
Starobinsky-like inflationary models as avatars of no-scale supergravity
Models of cosmological inflation resembling the Starobinsky R+R2 model emerge naturally among the effective potentials derived from no-scale SU(N,1)/SU(N) × U(1) supergravity when N > 1. We display
Quantum-gravity analysis of gamma-ray bursts using wavelets
In some models of quantum gravity, space-time is thought to have a foamy structure with non-trivial optical prop- erties. We probe the possibility that photons propagating in vacuum may exhibit a
Potential Sensitivity of Gamma-Ray Burster Observations to Wave Dispersion in Vacuo
The recent confirmation that at least some gamma-ray bursters (GRBs) are indeed at cosmological distances raises the possibility that observations of these could provide interesting constraints on
OBSERVABLES IN LOW-ENERGY SUPERSTRING MODELS
We compile phenomenological constraints on the minimal low-energy effective theory which can be obtained from the superstring by Calabi-Yau compactification. Mixing with the single additional neutral
