The universe was created 13.7 billion years ago in a blaze of light: the big bang. Roughly 380,000 years later, after matter (mostly hydrogen) had cooled enough for neutral atoms to form, light was able to traverse space ...

A graphene solution for microwave interference

Microwave communication is ubiquitous in the modern world, with electromagnetic waves in the tens of gigahertz range providing efficient transmission with wide bandwidth for data links between Earth-orbiting satellites and ...

New revelations on dark matter and relic neutrinos

The Planck collaboration, which notably includes the CNRS, CEA, CNES and several French universities, has disclosed, at a conference in Ferrara, Italy, the results of four years of observations from the ESA's Planck satellite. ...

Heat transfer sets the noise floor for ultrasensitive electronics

A team of engineers and scientists has identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes and advanced physics ...

Universe older than it looks

When astronomers (Bond 2013) first dated the star HD 140283, which lies a mere 190 lightyears from Earth in the constellation of Libra, they were puzzled. This rare, star appeared to be rather ancient and was quickly nicknamed ...
