True Origin of the Man in the Moon

New data obtained by NASA’s GRAIL mission reveals that the Procellarum region on the near side of the moon — a giant basin often referred to as the “man in the moon” — likely arose not from a massive asteroid strike, but from a large plume of magma deep within the moon’s interior. 

The effectiveness of current laser-propulsion techniques is limited by the instability of supersonic gas flow, caused by shock waves that “choke” the inlet of the nozzle, reducing thrust. Those effects can be reduced with the help of laser ablation, redir

Supersonic Laser-propelled Rockets may Enable Aircraft to Exceed Mach 10

October 31, 2014 2:21 pm | by The Optical Society | Comments

Scientists and science fiction writers alike have dreamed of aircrafts that are propelled by beams of light rather than conventional fuels. Now, a new method for improving the thrust generated by such laser-propulsion systems may bring them one step closer to practical use. A new system integrates a laser-ablation propulsion system with the gas blasting nozzles of a spacecraft. 

A new system lets programmers identify sections of their code that can tolerate a little error. The system then determines which program instructions to assign to unreliable hardware components, to maximize energy savings while still meeting the programme

Harnessing Error-prone Chips Trades Computational Accuracy for Energy Savings

October 31, 2014 2:09 pm | by Larry Hardesty, MIT | Comments

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation.

How does a normal cellular process derail and become unhealthy? A multi-institutional, international team led by Virginia Tech researchers studied cells found in breast and other types of connective tissue and discovered new information about cell transitions that take place during wound healing and cancer.

Nikon has revealed the winners of the 40th annual Nikon Small World Photomicrography Competition, awarding first prize to veteran competitor Rogelio Moreno of Panama for capturing a rarely seen image of a rotifer’s open mouth interior and heart-shaped corona. A computer system programmer by occupation, Moreno is a self-taught microscopist whose photomicrograph serves to show just how close the beauty and wonder of the micro-world truly is.

Projecting a Robot’s Intentions: New Spin on Virtual Reality to Read Robots’ Minds

October 30, 2014 4:46 pm | by Jennifer Chu, MIT | Comments

In a darkened, hangar-like space inside MIT’s Building 41, a small, Roomba-like robot is trying to make up its mind. Standing in its path is an obstacle — a human pedestrian who’s pacing back and forth. To get to the other side of the room, the robot has to first determine where the pedestrian is, then choose the optimal route to avoid a close encounter.

New Algorithm Provides Enormous Reduction in Computing Overhead

October 30, 2014 4:37 pm | by University of Luxembourg | Comments

The control of modern infrastructure, such as intelligent power grids, needs lots of computing capacity. Scientists have developed an algorithm that might revolutionize these processes. With their new software, researchers are able to forego the use of considerable amounts of computing capacity, enabling what they call micro mining.

Superconductors and magnetic fields do not usually get along. But a research team has produced new evidence for an exotic superconducting state, first predicted a half-century ago, that can indeed arise when a superconductor is exposed to a strong magnetic field.

Ancient Art Form of Origami Launches into Space

October 29, 2014 9:57 am | by Miles O'Brien and Marsha Walton, NSF | Comments

Most people who know of origami think of it as the Japanese art of paper folding. Though it began centuries ago, origami became better known to the world in the 20th century when it evolved into a modern art form. In the 21st century, origami has caught the attention of engineers who are using it to create all sorts of new structures — from collapsible packaging to airbags for cars. Origami has even found its way into space.

Mobile Phone Mapping Proves Reliable

October 28, 2014 1:58 pm | by University of Southampton | Comments

A study by an international team, including the University of Southampton, has shown population maps based on anonymous mobile phone call record data can be as accurate as those based on censuses. Their findings show maps made using mobile records are detailed, reliable and flexible enough to help inform infrastructure and emergency planners; particularly in low income countries, where recent population density information is often scarce.
