Greenpeace challenges popular solutions for reducing plastic pollution
A recent report from Greenpeace concludes that some of the most popular solutions for curbing plastics pollution are, in fact, not solutions at all and actually contribute to the growing problem.
Tackling three challenges to foster wind energy expansion
Meeting the challenges will drive the innovation needed for wind to become a primary source of low-cost electricity generation.
Team to re-enact the Mayflower voyage using fully autonomous ship
To mark the 400th anniversary of the Mayflower voyage, a U.K.-based marine research organization is teaming with IBM to build a fully autonomous ship to re-enact the Mayflower’s original journey from the U.K. to America.
Breaking point: Researchers work to refine material failure prediction models
Given the same basic information about the shape, composition and loading of a metal part, could teams of researchers predict how the part would eventually fracture?
Astronauts 3D print space meat
Astronauts aboard the International Space Station (ISS) have created lab-grown meat in space, according to reports.
