Sandia Labs simulates Android network to study cyber security

More and more people rely on their smartphones for most of their computing needs. However, the ubiquity of mobile devices and their communications networks opens up new opportunities for rogue cyber behavior. In order to better understand security risks associated with smartphones, Sandia National Laboratories in the U.S. has created a simulated network of 300,000 Android smartphones. Read More

World's smallest neutron generator – it's not just for nukes anymore

Neutron generators provide materials analysis and non-destructive testing tools to many industries, including oilfield operations, heavy mechanical construction, art conservancy, detective work, and medicine. Many of these applications have been limited by the rather large size of current industrial and medical neutron sources. Now Sandia National Laboratories, the lab that develops and supports the non-nuclear parts (including neutron generators) of nuclear weapons, has developed a new approach toward building tiny neutron generators.

Sandia modular robot hand brings a delicate touch to bomb disposal

Robots have been used routinely in bomb disposal for over forty years. Unfortunately, the standard way that robots deal with bombs is to blow them up. This removes the threat, but it also destroys valuable evidence that could lead to catching the bomb makers. Sandia National Laboratories has developed a new robot hand that is not only delicate enough to disarm a bomb rather than detonating it, but is relatively inexpensive and can even mend itself.Read More

Tiny new air samplers could aid in climate research

The monitoring of air quality can be a tricky business. Gases may be blown into the sampling site from another area, they may leak out of an air sample before it can be analyzed, or the sampling container itself may introduce compounds, emitted through off-gassing. If samples are being gathered in remote areas, it can also be difficult getting bulky equipment to and from the sampling site. Now, scientists from Sandia National Laboratories have announced a tiny new type of air sampler, that addresses these and other challenges.Read More

Nuclear UAV drones could fly for months at a time

Nuclear-powered unmanned aerial vehicles (UAVs) that would increase operational flight durations from days to months are a technological possibility today, according to a feasibility study undertaken last year by Sandia National Laboratories and Northrop Grumman Systems Corporation. A nuclear power supply would additionally double the availability of electrical power to onboard systems, including weaponry, the study found.Read More

Sandia simulation suggests sunny skies for fusion reactors

In the beginning, there was the thermonuclear bomb - mankind had harnessed the energy of the Sun. Confident predictions abounded that fusion reactors would be providing power "too cheap to meter" within ten years. Sixty years later many observers are beginning to wonder if billions of dollars of effort has been lost in digging out dry wells. Now a new simulation study carried out at Sandia National Laboratories in Albuquerque, New Mexico, suggests that magnetized inertial fusion (MIF) experiments could be retrofitted to existing pulsed-power facilities to obtain fusion break-even.

"Interface scaffolds" could wire prosthetics directly into amputees' nervous systems

Scientists at Sandia National Laboratories have announced a breakthrough in prosthetics that may one day allow artificial limbs to be controlled by their wearers as naturally as organic ones, as well as providing sensations of touch and feeling. The scientists have developed a new interface consisting of a porous, flexible, conductive, biocompatible material through which nerve fibers can grow and act as a sort of junction through which nerve impulses can pass to the prosthesis and data from the prosthesis back to the nerve. If this new interface is successful, it has the potential to one day allow nerves to be connected directly to artificial limbs.Read More

Hybrid fiber optic cable carries data and power

When you want to isolate communications between two devices or locations, a fiber optic link is one of the best ways to go. Under some circumstances, however, you might also want to isolate the transmission of power – in situations where traditional copper wire might prove unsafe or impractical, for instance. That’s why researchers at Sandia National Laboratories are developing a power-over-fiber (PoF) communications cable. It carries not only data, but also optical power.Read More

Newly discovered molecule has potential to offset climate change and cool the planet

Researchers claim a newly discovered molecule found in the Earth’s atmosphere holds the potential to help offset global warming by actually cooling the planet. The molecule is a Criegee biradical or Criegee intermediate, which are chemical intermediaries that are powerful oxidizers of pollutants produced by combustion, such as nitrogen dioxide and sulfur dioxide. They have the ability to naturally clean up the atmosphere by helping break down nitrogen dioxide and sulfur dioxide to form sulfate and nitrate, which ultimately leads to cloud formation that could help cool the planet.Read More
