Theres sweet news about hot cocoa: Researchers at Cornell University have shown that the popular winter beverage contains more antioxidants per cup than a similar serving of red wine or tea and may be a healthier choice.
The study adds to growing evidence of the health benefits of cocoa and points to a tasty alternative in the quest to maintain a diet rich in healthy antioxidants, chemicals that have been shown to fight cancer, heart disease and aging, the researchers say.
Their study, which they say is the most complete comparison to date of the total antioxidant content of these three popular beverages, will appear in the Dec. 3 issue of the Journal of Agricultural and Food Chemistry, a peer-reviewed journal of the American Chemical Society, the worlds largest scientific society.

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...
