A new 3D display should reduce the eye strain currently associated with devices like Googl...

Researchers at the University of Arizona and the University of Connecticut have developed a technology for augmented reality devices that superimposes data over three dimensions rather than two. The technique makes the user experience much more seamless and vastly reduces eye strain, making AR devices more attractive for long-term use.  Read More

NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) may have only come back online last September after a 31-month hibernation, but it’s already producing results. According to the space agency, the unmanned spacecraft discovered a never-before-seen asteroid on December 29 – the first discovery of its new mission to seek out potentially hazardous near-Earth objects (NEOs).  Read More

Earth saw in the New Year with some celestial fireworks as the first asteroid to be discovered this year, 2014AA, likely impacted the Earth between 7 pm Wednesday and 2 pm Thursday GMT.  Read More

The GMT will be completed in 2020 and sport a resolution 10 times greater than the Hubble ...

Slated for completion by 2020, the Giant Magellan Telescope (GMT) will combine seven of the largest and most precisely built telescope mirrors, to offer image resolutions 10 times greater than Hubble at around one third of the cost. The telescope will be used to study the early universe and answer open questions on dark matter, supermassive black holes, and the nature of planets beyond our solar system.  Read More

A petri dish of the sulfur-based polymer next to a (very small) stockpile of sulfur powder...

Whether sulfur is a by-product or a waste product of oil refinement and coal combustion depends on how you slice it. Certainly, some of that sulfur can be put to use producing sulfuric acid, fertilizer and other chemicals, but much of it is accumulating into stockpiles that are expensive to maintain (due to the need to neutralize acidic run-off). Researchers at the University of Arizona think more of that sulfur could be put to use thanks to a new chemical process that uses sulfur to make plastics that may one day be used to make a new generation of lighter, more efficient lithium-sulfur batteries.  Read More

Hubble Ultra Deep Field, showing thousands of galaxies back to a time only a few hundred m...

It is dangerous to bet against Einstein. Cosmological research shows that the rate at which the Universe expands is increasing, rather than decreasing as was previously thought. The concept of "dark energy" with a negative pressure was introduced to describe this acceleration. Now measurements of the proton to electron mass ratio (PEMR) over the past seven billion years strongly suggest that the models of dark energy are far more contrived in explaining accelerating expansion than is Einstein's self-proclaimed "biggest blunder" – the cosmological constant.  Read More

The InfinitiPipe can be manufactured on site (Image: University of Arizona)

A University of Arizona professor has invented a theoretically infinite pipe that promises to bring down the costs of laying pipelines while reducing environmental damage. Developed by Mo Ehsani, Professor Emeritus of Civil Engineering at the University of Arizona, the new pipe, called InfinitiPipe, is of a lightweight plastic aerospace honeycomb under layers of resin-saturated carbon fiber fabric put together by a new fabricating process that allows pipes to be built in indefinite lengths on site.  Read More

A dish-shaped mirror focuses sunlight onto a glass ball, which distributes it evenly onto ...

Borrowing technology from sophisticated telescope mirrors as well as high-efficiency solar cells used for space exploration, a group of students and researchers at the University of Arizona are putting the final touches on a novel power plant that promises to generate renewable energy twice as efficiently as standard solar panel technology with highly competitive costs and a very small environmental impact.  Read More

This biologically accurate set of robotic legs comprises simplified versions of the human ...

Moving forwards on two legs is one thing, walking with a recognizably human gait is quite another. While most humanoids have mastered the former, the latter is beyond the reach of most bipedal robots (though some are doing a good job at it) ... and there is a good reason for that. Recreating the way humans walk takes recreating the entire walking apparatus, complete with the skeletal, muscular and neural systems. That’s exactly what a group of researchers from the University of Arizona have done, creating what is reportedly the most biologically accurate set of robotic legs to ever walk the planet.  Read More

While digital cameras such as the Hasselblad H4D-200MS and Nikon D800 have pushed the megapixel boundary in recent times, and Nokia’s inclusion of a 41-megapixel camera into its 808 PureView smartphone got plenty of attention, researchers at Duke University and the University of Arizona say the age of consumer gigapixel cameras are just around the corner – and they’ve created a prototype gigapixel camera to prove it.  Read More
