No one keeps time quite like NASA.

Last month, the space agency's next-generation atomic clock was joined to the spacecraft that will take it into orbit in late 2017.

That instrument, the Deep Space Atomic Clock was developed by NASA's Jet Propulsion Laboratory in Pasadena, California. On Feb. 17, JPL engineers monitored integration of the clock on to the Surrey Orbital Test Bed spacecraft at Surrey Satellite Technology in Englewood, Colorado.

Yale scientists have developed an ultra-thin coating material that has the potential to extend the life and improve the efficiency of lithium-sulfur batteries, one of the most promising areas of energy research today.

In a study published online March 20 in the Proceedings of the National Academy of Sciences, researchers describe the new material — a dendrimer-graphene oxide composite film — which can be applied to any sulfur cathode. A cathode is the positive terminal on a battery.

A research team led by University of Toronto's Faculty of Applied Science & Engineering ‘squashes’ the shape of nanoparticles, enabling inexpensive lasers that emit light in a customized rainbow of colours

International research team warns of mineral supply constraints as demand increases for green technologies

An international team of researchers, led by the University of Delaware’s Saleem Ali, says global resource governance and sharing of geoscience data is needed to address challenges facing future mineral supply.

Specifically of concern are a range of technology minerals, which are an essential ingredient in everything from laptops and cell phones to hybrid or electric cars to solar panels and copper wiring for homes. However, base metals like copper are also a matter of immense concern.

ELECTRIC TRUCKS OFFER all the advantages of electric cars, namely, they’re greener. Trucks are a big source of the noxious emissions linked to smog and climate change. Minimizing the number of stinky, dirty diesels rumbling through town carries obvious public health benefits. But powering delivery trucks, let alone an 18-wheeler, with a big honkin’ battery simply isn’t practical. So engineers are taking another look at a century old solution: Stringing electrical cables over the road.

Chemists at FAU have developed a process in which nitrogen oxides generated during industrial processes can be used in the manufacture of colourants and medicines. Using the method, businesses will in future be able to combine the decontamination of exhaust fumes with the production of new substances.

Nitrogen oxides are a major environmental pollutant. Nitrogen and oxygen compounds are primarily formed during combustion, for example in automobile engines and coal and gas power plants, but also through other thermal and chemical techniques employed by industry. In order to clean these waste gases, the methods of post-combustion capture or catalytic reduction are employed – both of which are relatively complex and are also associated with certain disadvantages. But nitrogen oxides are not just unwanted toxins. In fact, recent research has shown that they can be used in the chemical synthesis of high-value products.

China's severe winter air pollution problems may be worsened by changes in atmospheric circulation prompted by Arctic sea ice loss and increased Eurasian snowfall – both caused by global climate change.

Slow wi-fi is a source of irritation that nearly everyone experiences. Wireless devices in the home consume ever more data, and it’s only growing, and congesting the wi-fi network. Researchers at Eindhoven University of Technology have come up with a surprising solution: a wireless network based on harmless infrared rays. The capacity is not only huge (more than 40Gbit/s per ray) but also there is no need to share since every device gets its own ray of light. This was the subject for which TU/e researcher Joanne Oh received her PhD degree with the ‘cum laude’ distinction last week.

Expertise is clearly beneficial in the workplace, yet highly trained workers in some occupations could actually be at risk for making errors when interrupted, indicates a new study by two Michigan State University psychology researchers.

Using a powerful telescope, scientists view spiral pattern of gaseous emissions around LL Pegasi and its companion star.
