Behold the world’s oldest sandals, buried in a “bat cave” over 6,000 years ago ( arstechnica.com )

In the 19th century, miners in southern Spain unearthed a prehistoric burial site in a cave containing some 22 pairs of ancient sandals woven out of esparto (a type of grass). The latest radiocarbon dating revealed that those sandals could be 6,200 years old—centuries older than similar footwear found elsewhere around the...

Tungsten oxide hydrate: the future of smart windows ( interestingengineering.com )

ABSTRACT: The independent modulation of visible and near-infrared light by a single material, termed dual-band electrochromism, is highly desirable for smart windows to enhance the energy efficiency of buildings. Tungsten oxides are commercially important electrochromic materials, exhibiting reversible visible and near-infrared...

World Community Grid passes 820,000 years of donated computation time towards finding new genetic predictors of cancer ( www.worldcommunitygrid.org )

World Community Grid is a volunteer computing project where people can donate their computer's spare computational power to science (similar to folding@home). This week they announced some results of their research and having passed the 800,000 CPU-year mark which is pretty incredible....

Harvesting almost-unlimited energy (in tiny amounts) from ripples in graphene ( interestingengineering.com )

Scientists have figured out how to harness Brownian motion -- literally the thermal energy of individual molecules -- to make electricity, by cleverly connecting diodes up to pieces of graphene, which are atom-thick sheets of Carbon. The team has successfully demonstrated their theory (which was previously thought to be...
