Is a sun-powered space laser the answer to stopping major asteroid impacts? (Photo: Shutte...

This past Friday was not a good day for asteroid-human relations with asteroid 2012 DA14 passing a mere 27,700 km (17,200 miles) from the Earth just a few hours after a meteor exploded over the Russian city of Chelyabinsk, damaging hundreds of buildings and injuring thousands. Scientists have been quick to point out that both of these events – a meteor exploding over a populated area and a large asteroid passing through Earth's geosynchronous orbit – are quite rare, but when the worst case scenario is the complete annihilation of all life on Earth, it's probably best to be prepared. That's why researchers in California recently proposed DE-STAR – a system which could potentially harness the sun's energy to dissolve wayward space rocks up to ten times larger than 2012 DA14 with a vaporizing laser.  Read More

Combining nanotechnology and microfluidics, researchers at UC Santa Barbara have created a high-performance detector that draws inspiration from the anatomy of a dog's nose to accurately identify substances – including explosives and narcotics – from very small concentrations of airborne molecules.  Read More

John Martinis’ research group at the University of California at Santa Barbara has created the first quantum computer with the quantum equivalent of conventional Von Neumann architecture. This general-purpose programmable quantum computer is realized using superconducting circuits and offers greater potential for large-scale quantum computing than the one-problem devices that have been demonstrated in this emerging field to date.  Read More

An electromagnetic waveguide placed on diamond crystals can deliver fields strong enough t...

Scientists at UC Santa Barbara have made important advances in the field of spintronics by demonstrating the ability to electrically manipulate, at room temperatures, the quantum states of electrons trapped in the atomic structural defects of diamond crystals. Despite previous indications to the contrary, such quantum states can be manipulated very quickly, even at gigahertz frequencies, paving the way to significantly faster quantum computing.  Read More

Scientists at UC Santa Barbara have developed a biological mechanism that can act as an entirely new means of drug delivery, carrying with it the potential to make treating illness even more effective. Rather than simply circulating in the bloodstream, the laboratory-developed peptide can deliver nanoparticles directly into tissue.  Read More
