Amber fossil reveals ancient reproduction in flowering plants

A 100-million-year old piece of amber has been discovered which reveals the oldest evidence of sexual reproduction in a flowering plant – a cluster of 18 tiny flowers from the Cretaceous Period – with one of them in the ...

Granular model explains unusual behavior in sand

From a mechanical perspective, granular materials are stuck between a rock and a fluid place, with behavior resembling neither a solid nor a liquid. Think of sand through an hourglass: As grains funnel through, they appear ...

Scientists see water ice in fresh meteorite craters on Mars

(PhysOrg.com) -- Scientists are seeing sub-surface water ice that may be 99 percent pure halfway between the north pole and the equator on Mars, thanks to quick-turnaround observations from orbit of fresh meteorite impact ...

Materials for superconducting qubits

The connection between microscopic material properties and qubit coherence are not well understood despite practical evidence that material imperfections present an obstacle to applications of superconducting qubits. In a ...
