A new way of looking at the Earth's interior

Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments conducted by ETH researchers now show that this view is too simplistic. Their results solve a key problem ...

Tapping secrets of Aussie spider's unique silk

An international collaboration has provided the first insights into a new type of silk produced by the very unusual Australian basket-web spider, which uses it to build a lobster pot web that protects its eggs and trap prey.

"Better" copper means higher-efficiency electric motors

Researchers at Pacific Northwest National Laboratory (PNNL) have increased the conductivity of copper wire by about five percent. That may seem like a small amount but it can make a big difference in motor efficiency. Higher ...

Stacking and twisting graphene unlocks a rare form of magnetism

Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the ...

Wild birds as offerings to the Egyptian gods

Millions of ibis and birds of prey mummies, sacrificed to the Egyptian gods Horus, Ra or Thoth, have been discovered in the necropolises of the Nile Valley. Such a quantity of mummified birds raises the question of their ...

Scientists propose multifunctional liquid metal nanocapsules

Liquid metals (LMs) are promising for applications in flexible electronics and biomimetic functional composites. Nanometerization and surface modification of LMs are usually used to improve their substrate affinity and processing ...

The new composite prevents malfunctions of electronic devices

Scientists from South Ural State University, in collaboration with colleagues from Belarus, India and China, have created a composite material for nanoelectronics. The material can be used as a dielectric (insulating substance) ...
