As numerous companies continue their push to get us to entrust our data to the cloud, there are many still justifiably concerned about the security of cloud computing-based services. Now an international team of scientists have demonstrated that perfectly secure cloud computing is possible by combining the power of quantum computing with the security of quantum cryptography. They carried out what they claim is the first demonstration of “blind quantum computing,” in which a quantum computation was carried out with the input, computation, and output all remaining unknown to the computer, and therefore, also any eavesdroppers.  Read More

Ever since University of Manchester scientists Andre Geim and Konstantin Novoselov first isolated flakes of graphene in 2004 using that most high-tech pieces of equipment - adhesive tape - the one-atom sheet of carbon has continued to astound researchers with its remarkable properties. Now Professor Sir Andre Geim, (he's now not only a Nobel Prize winner but also a Knight Bachelor), has led a team that has added superpermeability with respect to water to graphene's ever lengthening list of extraordinary characteristics.  Read More

Scientists have unlocked the secret to scorpions' ability to withstand sand-blasting, and ...

As any graffiti-removal specialist will tell you, sand-blasting is definitely an effective method of removing substances that have bonded onto hard surfaces. Unfortunately, sand or other abrasive particles suspended in air or liquid also have a way of eroding not just spray paint, but pretty much anything they encounter. As a result, items such as helicopter rotor blades, airplane propellers, rocket motor nozzles and pipes regularly wear out and need to replaced. Interestingly enough, however, scorpions live their entire lives subjected to blowing sand, yet they never appear to ... well, to erode. A group of scientists recently set out to discover their secret, so it could be applied to man-made materials.  Read More

We’ve previously seen – or should that be “not seen” – invisibility cloaks in the laboratory that are able to render two-dimensional objects invisible to microwaves. Such feats relies on the use of metamaterials – man-made materials that exhibit optical properties not found in nature and have the ability to guide light around an object. Now researchers at the University of Texas at Austin (UT) claim to have brought invisibility cloaks that operate at visible light frequencies one step closer by cloaking a three-dimensional object standing in free space with the use of plasmonic metamaterials.  Read More

Analysis of the way a goshawk flies through cluttered forests has revealed a critical safe...

Research into goshawk flight could inform the design of next generation UAVS. Where prior research into bird flight has focused on steady flight, new research from MIT examines the patterns of birds adept at flying in "cluttered environments" to find principles applicable to robot motion planning. It's research that might one day find practical applications in engineering, including fast, agile UAVs.  Read More

We recently looked at one of the potential contenders in the US$10 million Qualcomm Tricorder X PRIZE, which as the name suggests, was inspired by the medical tricorder of Star Trek fame. Now scientists have developed a new way of creating Terahertz (THz) or T-rays, which they say could help make handheld devices with tricorder-like capabilities a reality.  Read More

The Purdue microtweezers, which are said to be less expensive to produce than conventional...

In order to do things such as building microelectromechanical systems (MEMS) or grabbing individual stem cell spheres for analysis, scientists use extremely fine-tipped tools known as microtweezers. While such devices aren't a brand new innovation in and of themselves, researchers from Indiana's Purdue University have developed a new type of microtweezers that are said to be easier and cheaper to manufacture than their conventional counterparts. Not only that, but unlike most similar devices currently in use, they don't require heat, magnetism or electricity to operate.  Read More

Scientists at the University of California, San Diego, have created what they claim is the first self-propelling, hydrogen-bubble-powered "microrocket" requiring no external source of fuel. In the most acidic solutions, these micromotors can reach speeds of 100 body lengths per second. It's claimed that the breakthrough could pave the way (or rather line the esophagus) towards stomach-going nanomotors which could provide imaging or precisely targeted drug treatment. In addition to self-propulsion, the gut-rockets can be steered, and made to collect and release a payload.  Read More

When the moon-walking Apollo 11 astronauts returned to Earth in 1969, amongst the 47.5 pounds (21.5 kg) of lunar rocks they brought with them were three minerals from Tranquility Base that were thought to be unique to the Moon or lunar and possibly Martian meteorites. They were armalcolite (named after Neil Armstrong, Edwin ‘Buzz' Aldrin and Michael Collins), pyroxferroite and tranquillityite. Both armalcolite and pyroxferrite were later found on Earth, leaving tranquillityite as the last mineral believed to have no terrestrial counterpart. Now tranquillityite has also been struck off the list with its discovery in the remote Pilbara region of Western Australia.  Read More

IBM scientists in Zurich have created a proof-of-concept device, that could change the way that human tissue samples are analyzed. Presently, samples must be stained with a biomarker solution in order to detect the presence of a disease. The staining process can be quite involved, however, plus it is subject to error – too much of the solution can cause inaccurate results, for instance. Additionally, it can sometimes be difficult to perform enough tests using the small amount of tissue extracted in most biopsies. The IBM technology, though it still involves staining, is said to offer a potential solution to these shortcomings.  Read More
