We outline a dynamical dark energy scenario whose signatures may be
simultaneously tested by astronomical observations and laboratory
experiments. The dark energy is a field with slightly sub-gravitational
couplings to matter, a logarithmic self-interaction potential with a scale
tuned to $\sim 10^{-3} {\rm eV}$, as is usual in quintessence models, and
an effective mass $m_\phi$...

A discrete structure of space and time is often expected to result from a
quantum theory of gravity. Loop quantum gravity realizes this clearly at
least for space while time, in such a canonical quantization, is handled
more indirectly. Cosmological scenarios show how the discreteness of time,
unnoticeable at current scales, becomes an important feature in the early
universe. It plays a...

The LHC will begin data taking in the Summer of 2008.
We review the physics potential of the ATLAS and CMS experiments with
an emphasis on the new types of particles which might be produced in the
Proton-Proton collisions at 14 TeV.

We review the physics of the cosmic microwave background
anisotropies and how the early universe and cosmological
structure formation imprint their records into it.
We describe the status of the CMB experiments, pointing out the
CMB observables which are still beyond reach of the operating detectors.
Finally, we focus on the the expectations from Planck and future probes.

We review the physics in space times of higher than
4-dimensions with particular emphasis on two extra dimensions. Some recent results
about the spectrum of 3-brane with positive and negative tensions in
gauged supergravities in 6 dimensions will be
discussed. In these theories it is possible to be obtain large mass
gaps even in the large volume limit.

We study in detail the solution space for a class of sypersymmetric solutions to supergravity. The solutions fall into three classes, non-singular, null-singular and time machines with a time-like naked singularity. We study the general features of these metrics and prove that there are actually just two generic classes of space-times - those with null singularities are in the same class as...
