Photos of the Day: A self-organizing thousand-robot swarm

August 15, 2014 12:03 pm | by Harvard University | Comments

Just as trillions of individual cells can assemble into an intelligent organism, or a thousand starlings can form a great flowing murmuration across the sky, the Kilobots demonstrate how complexity can arise from very simple behaviors performed en masse....

Molecular engineers record an electron's quantum behavior

August 15, 2014 11:42 am | by EurekAlert! | Comments

A team of researchers led by the University of Chicago has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique uses ultrafast pulses of laser light both to control the defect's entire quantum state....

New Milky Way maps help solve stubborn interstellar material mystery

August 15, 2014 11:38 am | by EurekAlert! | Comments

An international team of sky scholars, including a key researcher from Johns Hopkins, has produced new maps of the material located between the stars in the Milky Way. The results should move astronomers closer to cracking a stardust puzzle that has vexed them for nearly a century....

Predicting fracking policy

August 15, 2014 11:06 am | by EurekAlert! | Comments

Hydraulic fracturing is emerging as one of the primary methods of drilling for natural gas, yet is equally controversial in its potential to induce harm to humans and the environment. The uncertainties of the health risks associated with horizontal drilling using fluid pressure ...

Engineering Live: The Beginning of the End for Wearable Devices

August 15, 2014 10:54 am | by ECN Staff | Comments

In 2013, wearable devices began to take off in the consumer and medical industries, particularly with fitness and health tracking devices. The NPD group believes that the market will swell to 91 million units in 2015, but some insiders predict that fitness wearables only have two more years....

Smarter ground robots partnering with soldiers

August 15, 2014 9:20 am | by U.S. Army | Comments

Heidi Shyu, assistant secretary of the Army for Acquisition, Logistics & Technology Shyu, provided the keynote address at National Defense Industrial Association's Ground Robotics Capabilities Conference & Exhibition in Hyattsville, Md., Aug. 13, 2014, emphasized common architecture, open-source ...

A self-organizing thousand-robot swarm

August 15, 2014 8:54 am | by EurekAlert! | Comments

The first thousand-robot flash mob has assembled at Harvard University. "Form a sea star shape," directs a computer scientist, sending the command to 1,024 little bots simultaneously via an infrared light. The robots begin to blink at one another and then gradually arrange themselves....

Memories of errors foster faster learning

August 14, 2014 4:59 pm | by EurekAlert! | Comments

Using a deceptively simple set of experiments, researchers at Johns Hopkins have learned why people learn an identical or similar task faster the second, third and subsequent time around. The reason: They are aided not only by memories of how to perform the task....

UT Arlington and Pediatrix partner to bring simulation training direct to practice

August 14, 2014 4:45 pm | by EurekAlert! | Comments

A real-time video feed, a laptop and a computerized manikin baby are key components for a new simulation training initiative that allows UT Arlington College of Nursing educators to put Neonatal Nurse Practitioners (NNPs) and physicians through the paces of an emergency scenario....

Scientists fold RNA origami from a single strand

August 14, 2014 4:42 pm | by EurekAlert! | Comments

RNA origami is a new method for organizing molecules on the nanoscale. Using just a single strand of RNA, many complicated shapes can be fabricated by this technique. Unlike existing methods for folding DNA molecules, RNA origamis are produced by enzymes....

Stardust team reports discovery of first potential interstellar space particles

August 14, 2014 4:17 pm | by NASA | Comments

Seven rare, microscopic interstellar dust particles that date to the beginnings of the solar system are among the samples collected by scientists who have been studying the payload from NASA's Stardust spacecraft since its return to Earth in 2006. If confirmed, these particles would be the first ...

University of Tennessee research uncovers forces that hold gravity-defying near-earth asteroid together

August 14, 2014 3:59 pm | by EurekAlert! | Comments

Researchers at the University of Tennessee, Knoxville, have made a novel discovery that may potentially protect the world from future collisions with asteroids. The team studied near-Earth asteroid 1950 DA and discovered that the body, which rotates so quickly it defies gravity ...

New test reveals purity of graphene

August 14, 2014 3:55 pm | by EurekAlert! | Comments

Graphene may be tough, but those who handle it had better be tender. The environment surrounding the atom-thick carbon material can influence its electronic performance, according to researchers at Rice and Osaka universities who have come up with a simple way to spot contaminants....

Single gene controls jet lag

August 14, 2014 2:25 pm | by EurekAlert! | Comments

LA JOLLA–Scientists at the Salk Institute for Biological Studies have identified a gene that regulates sleep and wake rhythms. The discovery of the role of this gene, called Lhx1, provides scientists with a potential therapeutic target to help night-shift workers....

New material could enhance fast and accurate DNA sequencing

August 14, 2014 2:20 pm | by EurekAlert! | Comments

Gene-based personalized medicine has many possibilities for diagnosis and targeted therapy, but one big bottleneck: the expensive and time-consuming DNA-sequencing process. Now, researchers at the University of Illinois at Urbana-Champaign ...
