Is dark matter made of primordial black holes?

Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of the matter in the universe was not visible. About 84 percent of ...

Polarization has strong impact on electrons, study shows

The movement of thousands of electrons underlies electronics. Yet, ubiquitous as electrons are, the particulars of their behavior continue to stump physicists. One phenomenon has proven especially puzzling: how electrons ...

CFRP recycling—into the battery instead of the garbage

Carbon fiber-reinforced plastics are gaining importance as components of aircraft. The trend is increasing the need for sustainable recycling concepts. At the ILA from April 25 to 29, 2018 in Berlin, Fraunhofer will present ...

A massive telescope for seeing the invisible

Some of the universe's greatest mysteries could soon be resolved thanks to the Square Kilometre Array (SKA), a huge radio telescope that will be built in South Africa and Australia. Several EPFL labs are involved in this ...

Unprecedentedly wide and sharp dark matter map

A research team of multiple institutes, including the National Astronomical Observatory of Japan and University of Tokyo, released an unprecedentedly wide and sharp dark matter map based on the newly obtained imaging data ...

The future of wireless communications is terahertz

Electrical and optical engineers in Australia have designed a novel platform that could tailor telecommunication and optical transmissions. Collaborating scientists from the University of New South Wales in Sydney and Canberra, ...

A new bound on axions

An axion is a hypothetical elementary particle whose existence was postulated in order to explain why certain subatomic reactions appear to violate basic symmetry constraints, in particular symmetry in time. The 1980 Nobel ...
