Math explains history: Simulation accurately captures the evolution of ancient complex societies

The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence of complex states in the ancient world. Intense warfare is the evolutionary driver of large complex societies, according to new research from a trans-disciplinary… Read More »

Users sue Linkedin over harvesting of email addresses

Four LinkedIn users have filed a lawsuit accusing the business-oriented social network of accessing their email accounts without permission, harvesting the addresses of their contacts and spamming those people with repeated invitations to join the service. In their most explosive claim, the plaintiffs say that LinkedIn is “breaking into” external email accounts, like Gmail or… Read More »

How Leon Foucault taught us to watch the world spin

Leon Foucault and his pendulum demonstrated the turning of the Earth. Google honored the French physicist with an interactive doodle. It’s easy to forget that while you read this article, you and your computer screen are racing through space at a nearly unimaginable speed. The earth constantly rotates on its axis at 1,037 miles per… Read More »

Archaeologists’ tricorder reveals objects’ ancient origins

Tricorder-style handheld scanners could help archaeologists uncover historical secrets without having to wait months for laboratory results. Researchers from Sheffield University have adapted technology used to identify materials in scrap metal yards and docks, in order to determine the geographical origin of certain stone tools in just 10 seconds. The portable scanner uses X-rays to… Read More »

UCI researchers fabricate new camouflage coating from squid protein

What can the U.S. military learn from a common squid? A lot about how to hide from enemies, according to researchers at UC Irvine’s Henry Samueli School of Engineering. As detailed in a study published online in Advanced Materials, they have created a biomimetic infrared camouflage coating inspired by Loliginidae, also known as pencil squids… Read More »

Massaging Vest Combats Stress While You Wear It

Grabbing a massage as you walk around town has never been so easy. A group of Cornell students recently invented an electric vest embedded with tiny motors intended to knead and massage the user’s back and shoulders. The vest, which was created in hopes of relieving stress linked to negative health effects, was even designed… Read More »

New Microplasma Device Could Potentially Revolutionize Archaeology

A team of researchers, including experts from Uppsala University in Sweden have developed a miniature device that they claim could revolutionize the way in which archaeologists date objects they discover in the field. The instrument in question is being described as a high-tech microplasma source that is capable of exciting matter in a controlled, efficient… Read More »

Virgin Galactic ship shakes its space-flight feathers

… The first vehicle purpose-built for carrying tourists into space has now tested not just its wings, but also its feathers. Although it still hasn’t reached space, Virgin Galactic’s SpaceshipTwo flew slightly longer and higher than it did on its first powered flight in April – and this time it also deployed a safety mechanism… Read More »

Robot spacecraft ready for launch to study moon dust, NASA says

Weather conditions were “looking real good” for NASA’s Friday night launch of a small robotic spacecraft on a mission to investigate the mysterious moon dust that Apollo astronauts encountered decades ago, a spokesman said. The Lunar Atmosphere and Dust Environment Explorer spacecraft, known as LADEE, is scheduled for launch at 11:27 p.m. EDT on Friday… Read More »

Earth telescope captures images twice as sharp as Hubble

Telescope captures images twice as sharp as Hubble Astronomers say they are now able to capture images of the sky that are twice as sharp as those captured by the Hubble telescope. A team of scientists from the University of Arizona, Arcetri Observatory in Italy and the Carnegie Observatory developed the technology that will allow… Read More »

RINGS propels satellites without propellants

Astronauts on the International Space Station (ISS) are testing a new propulsion system … inside the station. While this might seem like the height of recklessness, this particular system doesn’t use rockets or propellants. Developed in the University of Maryland’s Space Power and Propulsion Laboratory, this new electromagnetic propulsion technology called the Resonant Inductive Near-field… Read More »

Meet the NASA scientist devising a starship warp drive

To pave the way for rapid interstellar travel, NASA propulsion researcher Harold “Sonny” White plans to manipulate space-time in the lab The idea that nothing can exceed the speed of light limits our interstellar ambitions. How do we get round this? Within general relativity, there are two loopholes that allow you to go somewhere very… Read More »
