Biologists quote Lewis Carroll when arguing that survival is a constant struggle to adapt and evolve. Is that true, or do groups die out because they experience a run of bad luck? Charles Marshall and Tiago Quental of UC ...

Scientists find 3-D material that mimics 2-D graphene

(Phys.org) —Graphene—the thinnest and strongest known material in the universe and a formidable conductor of electricity and heat – gets many of its amazing properties from the fact that it occupies only two dimensions: ...

Why lithium-ion-batteries fail

Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of ETH scientists together with colleagues ...

New model of Earth's interior reveals clues to hotspot volcanoes

Scientists at the University of California, Berkeley, have detected previously unknown channels of slow-moving seismic waves in Earth's upper mantle, a discovery that helps explain "hotspot volcanoes" that give birth to island ...
