Why Keep Them Alive

Wear them, forget them.

Rods Feed Cones to Keep them Alive

Cone photoreceptors, responsible for high-resolution and color vision, progressively degenerate following the death of rod photoreceptors in the blinding disease retinitis pigmentosa. Aït-Ali et al. describe a molecular mechanism by which RdCVF, a factor normally released by rods, controls glucose entry into cones, enhancing their survival.

Fantastic species and where to find them

Fantastic beasts are not only found in the imaginary worlds of authors like J.K. Rowling. The oceans are full of them. Michael Gross rounds up some unusual suspects.

Burst Remnants : How can we find them ?

By now there is substantial evidence that Gamma-Ray Bursts (GRBs) originate at cosmological distances from very powerful explosions. The interaction between a GRB and its surrounding environment has dramatic consequences on the environment itself. At early times, the strong X-ray UV afterglow flux photoionizes the medium on distance scales on the order of 100 pc [7], destroys dust [10], creates...
