Astronomers led by David Sobral and Jorryt Matthee, of the Universities of Lancaster in the UK and Leiden in the Netherlands have discovered giant halos around early Milky Way type galaxies, made of photons (elementary particles of light) that have struggled to escape them.
Scientists behind a theory that the speed of light is variable - and not constant as Einstein suggested - have made a prediction that could be tested.
Galaxies formed and grew billions of years ago by accumulating gas from their surroundings, or colliding and merging with other young galaxies.
Researchers from The University of Manchester have taken a significant step closer to demonstrate that it is possible to create miniscule - but very powerful - computers that could work at atomic scale.

The IRTracer-100 FTIR Spectrophotometer from Shimadzu has an improved interferometer and detector design. It offers superior sensitivity with a 60,000:1 S/N ratio
Electro-optic modulators (EOMs) are an easy to use and efficient tool to externally modify the phase, frequency, polarization or amplitude of a free-space laser. In contrast to acousto-optic modulators the spatial mode of the laser beam remains unaltered.
QUANTIS is a physical random number generator, which uses a fundamental quantum optics process. Quantis needs to be used along with a server or computer. The product is offered in three versions, which is compatible with most platforms.
