The lure of a seafood diet may explain why early humans came out of Africa, according to research by the universities of Leeds and Glasgow published in Science this week.
Early modern humans in East Africa survived on an inland diet based on big game but by 70,000 years ago their diet had changed to a coastal one consisting largely of shellfish. However, dramatic climate change seems likely to have reduced the Red Seas shellfish stocks. New DNA evidence suggests their taste for life beside the sea caused them to set off from Africa to find new, better fishing grounds.
The international project shows – contrary to previous thinking – that early modern humans spread across the Red Sea from the Horn of Africa, along the tropical coast of the Indian Ocean towards the Pacific, in just a few thousand years.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
