The Raspberry Pi — about 3 inches by 2 inches and less than an inch high — was intended to replace the expensive computers in school science labs. For less than the price of a new keyboard, a… read more
The Watson system will enable upstate New York-based RPI to find new uses for Watson and deepen the systems’ cognitive capabilities, IBM says.
Watson has a unique ability to understand the subtle nuances of human language, sift… read more
DARPA and the US Army have taken the wraps off ARGUS-IS, a 1.8-gigapixel video surveillance platform that can resolve details as small as six inches from an altitude of 20,000 feet (6km), ExtremeTech reports.
ARGUS is by far the highest-resolution surveillance platform in the world, and probably the highest-resolution camera in the world, period.
ARGUS, which would be attached to some kind of unmanned UAV (such as… read more
A small asteroid named 2012 DA14 will pass inside the geosynchronous satellite ring on February 15, but the orbit will be no closer to the Earth’s surface than 3.2 Earth radii , according to NASA JPL..
Although its size is not well determined, this near-Earth asteroid is thought to be about 45 meters in diameter.
Stanford Engineering‘s Center for Turbulence Research (CTR) has set a new record in computational science by successfully using a supercomputer with more than 1.5 million computing cores to solve a complex fluid dynamics problem: the prediction of noise generated by a supersonic jet engine.
Joseph Nichols, a research associate in the center, worked on the newly installed Sequoia IBM Bluegene/Q system at Lawrence Livermore National Laboratories (LLNL)… read more
The first trial comparing a new dual-hormone “artificial pancreas” with conventional diabetes treatment using an insulin pump has been completed by researchers at IRCM (Institut de Recherches Cliniques) of Montreal, led by endocrinologist Dr. Rémi Rabasa-Lhoret. It showed improved glucose levels and lower risks of hypoglycemia.
How it works
The artificial pancreas developed at IRCM is an automated system that simulates the normal pancreas by… read more
About 25 miles northeast of Sacramento, U.S. Army Corps of Engineers Sacramento District construction crews are working to complete one of the Corps’ biggest projects — a new spillway at Folsom Dam, designed to help reduce the risk of flooding throughout the Sacramento region.
With an estimated project cost of more than $750 million, it’s important to be able to show and describe how the project will… read more
Vaccines usually consist of inactivated viruses that prompt the immune system to remember the invader and launch a strong defense if it later encounters the real thing. However, this approach can be too risky with certain viruses, including HIV.
In recent years, many scientists have been exploring DNA as a potential alternative vaccine. About 20 years ago, DNA coding for viral proteins was found to induce strong immune responses… read more
Shanghai Institute of Optics and Fine Mechanics in China physicists have designed and built a remote-sensing “ghost imaging” device that uses a single pixel to record three-dimensional images, MIT Technology Review reports.
Ghost imaging is the extraordinary technique of bouncing a laser beam off an object and making high quality images from the reflected light using a single pixel. This single pixel is used to record data… read more
The sophisticated electronics used by warfighters in everything from radios, remote sensors and even phones can now be made at such a low cost that they are pervasive throughout the battlefield. But it is almost impossible to track and recover every device.
These electronics are often found scattered across the battlefield and might be captured by the enemy and repurposed or studied to compromise DoD’s strategic technological advantage.… read more
In a development that could lead to faster and more effective toxicity tests for airborne chemicals, scientists from Rice University and the Rice spinoff company Nano3D Biosciences have used magnetic levitation to grow some of the most realistic lung tissue ever produced in a laboratory.
Recent patent applications related to Google Glass are providing insight into the hardware behind the Glasses.
Bone conduction for covert audio. This would allow more privacy so that no one can overhear a conversation; a vibration transducer allows the technology to work without a direct connection. U.S. patent application
A laser projector can be used to project an interface on… read more
Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells.
The first-ever antimicrobial hydrogel that can break apart biofilms and destroy multidrug-resistant superbugs upon contact has been developed by researchers from the Institute of Bioengineering and Nanotechnology (IBN) and IBM Research.
Tests have demonstrated the effectiveness of this novel synthetic material in eliminating various types of bacteria and fungi that are leading causes of microbial infections, and preventing them from developing antibiotic resistance.
