New metamaterial is proved to be the world’s first to achieve the performance predicted by theoretical bounds

In 2015 UC Santa Barbara mechanical engineer and materials scientist Jonathan Berger developed an idea that could change the way people think about high-performance structural materials. Two years later, his concept is paying research dividends.

Genetic data show mainly men migrated from the Pontic steppe to Europe 5,000 years ago

A new study, looking at the sex-specifically inherited X chromosome of prehistoric human remains, shows that hardly any women took part in the extensive migration from the Pontic-Caspian Steppe approximately 5,000 years ago. The great migration that brought farming practices to Europe 4,000 years earlier, on the other hand, consisted of both women and men. The difference in sex bias suggests that different social and cultural processes drove the two migrations.

Fermi finds possible dark matter ties in Andromeda galaxy

NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

New design for longer lasting night-vision cameras

With the amazing ability to survey areas in complete darkness, night-vision cameras have revolutionized the security industry. But the materials and technology embodied in current cameras tend to degrade under temperature stress, causing night-vision devices to frequently break.
