Who's that tiny dancer in the aisles of the Consumer Electronics Show? It's Ozobot, the world's smallest programmable robot with an intuitive color-based language. Ozobot's capacity for fun and learning is designed to bridge the physical and digital divide, and the “smart game piece” glides seamlessly from paper to digital tablet. Playing with the robot introduces kids and young adults to simple coding basics...
Devising a way to one day land astronauts on Mars is a complex problem, and NASA scientists think something as simple as a child's toy design may help to solve it. Safely landing a large spacecraft on the Red Planet is just one of many challenges the agency faces as it eyes an ambitious goal of sending humans into deep space. NASA has been developing an inflatable heat shield that looks a lot like a super-sized stacking ring of doughnuts.
High-energy jets powered by supermassive black holes can blast away a galaxy’s star-forming fuel, resulting in so-called "red and dead" galaxies: those brimming with ancient red stars yet containing little or no hydrogen gas to create new ones. However, astronomers using ALMA have discovered that black holes don’t have to be nearly so powerful to shut down star formation. They have detected a “perfect storm” of turbulence ...
Prospects of developing computing and communication technologies based on quantum properties of light and matter may have taken a major step forward. In a pioneering study, researchers were able to discover half-light, half-matter particles in atomically thin semiconductors consisting of a 2-D layer of molybdenum and sulfur atoms arranged similar to graphene.
Researchers are closer to creating underwater robotic creatures with a brain of their own — besides behaving like the real thing. In the near future, it would not be too tall an order for the National University of Singapore (NUS) team to produce a swarm of autonomous tiny robotic sea turtles and fishes, for example, to perform hazardous missions, such as detecting nuclear wastes underwater or other tasks too dangerous for humans.
With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades — such as pneumonia — are proving trickier to treat with standard antibiotics. New drugs are desperately needed, but so are ways to maximize the effective lifespan of these drugs. Researchers used software they developed to predict a constantly-evolving infectious bacterium's countermoves to one of these new drugs ahead of time...
This 10x photo of the larval stage of the acorn worm Balanoglossus misakiensis, dorsal view, shows cell borders, muscles and apical eye spots. It won 19th Placein the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken by Dr. Sabrina Kaul of theUniversity of Vienna, Austria, using confocal microscopy.
There are no garbage trucks equipped to leave the atmosphere and pick up debris floating around the Earth. But what if we could send a robot to do the job? Scientists at NASA's Jet Propulsion Laboratory are working on adhesive gripping tools that could grapple objects, such as orbital debris or defunct satellites, that would otherwise be hard to handle.
Since its earliest days, the FBI has looked for recruits with specialized skills to fill its special agent ranks. Today, the most sought-after candidates possess a uniquely 21st century quality: cyber expertise. To keep pace with the evolving threat, the Bureau is appealing to experienced and certified cyber experts to consider joining the FBI to apply their well-honed tradecraft as cyber special agents.
What time is it? The answer, no matter what your initial reference may be, will always trace back to the atomic clock. The international standard for time is set by atomic clocks — room-sized apparatuses that keep time by measuring natural vibration of atoms in a vacuum. Researchers have come up with a new approach to atomic timekeeping that may enable more stable and accurate portable atomic clocks, potentially the size of a Rubik’s cube.
This 25x photo of a house cricket's tongue won 11th Placein the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Stefano Barone of Cremona, Italy, using Rheinberg illumination.
The OpenPOWER Foundation, an open development community dedicated to accelerating data center innovation for POWER platforms, has announced its first OpenPOWER Summit will be held March 17 to 19, 2015, at the San Jose Convention Center. It will be hosted within the GPU Technology Conference, which has thousands of technology sector attendees, including developers, researchers, government agencies and industry luminaries.
An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for super-thin devices, according to Rice University researchers. Although one such material, copper indium selenide, shows extraordinary promise.
Computer scientists have extended two popular browsers to empower developers to deliver creative new services while also make surfing safer. The team added a security system called COWL, or Confinement with Origin Web Labels, to Firefox and Chrome to manage how data is shared. It prevents malicious computer code from leaking sensitive information and, at the same time, allows Web applications to display content drawn from multiple sources.
Unlike in mathematics, it is rare to have exact solutions to physics problems. The first exact solution that describes a system expanding at relativistic velocities radially and longitudinally has been presented by researchers. It applies to a wide array of physics contexts and will help to better model galactic structure, supernova explosions and high-energy particle collisions, such as those studied at the Large Hadron Collider at CERN.
