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

A team of engineering researchers at the University of Michigan has developed a nanoscale coating that causes almost all liquids to bounce off surfaces treated with it. Consisting of at least 95 percent air, the new "superomniphobic" coating is claimed to repel the broadest range of liquids of any material in its class, opening up the possibility of super stain-resistant clothing, drag-reducing waterproof paints for ship hulls, breathable garments that provide protection from harmful chemicals, and touchscreens resistant to fingerprint smudges.  Read More

The swallowable capsule, and its tether

Barrett’s esophagus is a precancerous condition typically caused by chronic exposure to stomach acid, and is usually diagnosed by inserting an endoscope down the patient’s throat. A tool has been developed, however, that should allow for a quicker, easier way of getting a good look at such peoples’ esophagus – it’s a swallowable capsule that contains a spinning laser.  Read More

Fraunhofer's telerehabilitation system in use

Generally speaking, people tend to dislike doing the exercises that are part of physiotherapy. Not helping matters is the fact that in many cases, patients must travel to a clinic to perform those exercises under the supervision of a trained professional. Now, researchers from Germany’s Fraunhofer Institute for Open Communication Systems FOKUS are developing a “telerehabilitation” system that allows patients to perform exercises at home or when out and about, while still receiving feedback from a physiotherapist.  Read More

The Planet Four website

With the creation of new citizen science website Planet Four, planetary scientists are turning to the general public for help in analyzing images of the surface of Mars, many of which have never been seen before. It's hoped that the public's input will help develop a detailed picture of winds on the planet.  Read More

A new library to be opened in Bexar County, Texas, will provide visitors with a bank of e-Readers for borrowing e-books ... but books of the traditional paper variety will be glaringly absent. The project marks the first public library to be built as an all-digital service and just to make sure library-goers are in no doubt that it's the 21st century, the interior will feature a design influenced by Apple retail stores.  Read More

An asteroid passing close to Earth next month will provide stargazers with a rare viewing ...

Asteroid 2012 DA14 is about 40 meters (131 ft) in size, has a mass of 130,000 tons, is traveling relative to the Earth at a speed of some 6.3 km/s (14,100 mph) ... and will miss us by less than 32,000 km (20,000 miles) on February 15. If it did hit the Earth, the result would be a huge explosion yielding about 2.5 megatons, but Asteroid 2012 DA14 will not hit our planet in 2013, and probably never will. Despite the lack of a sensational scenario, this close call still warrants our attention – it will allow astronomers to learn a good deal about asteroids, and represents one of the few chances for ordinary folks to see a asteroid pass really close to Earth.  Read More

A team of researchers at MIT’s David H. Koch Institute for Integrative Cancer Research has developed a new polymer film that generates power from water vapor. Consisting of two polymer films, the material makes remarkably acrobatic somersaults in the presence of even tiny traces of evaporated water, opening the way for new types of artificial muscles for controlling robotic limbs or powering micro and nanoscopic devices.  Read More

Black holes blaze magenta in this NuStar photo of spiral galaxy IC342 (Photo: NASA)

Black holes, which abound in the Universe, convert matter into geometry – the larger the amount of matter that disappears through the event horizon, the larger they grow, with the only external sign of their presence being the warping of space due to their gravity. In the process, a great deal of extremely hot gas is generated, and that gas emits hard x-rays. Now NASA's NuSTAR space telescope can find black holes by forming high-resolution images of the cosmos in hard x-rays.  Read More

Two strands of the new CNT fiber support and supply current to an LED bulb

At about 100 times the strength of steel at one sixth the weight and with impressive electrical conductive properties, carbon nanotubes (CNTs) have promised much since their discovery in 1991. The problem has been translating their impressive nanoscale properties into real-world applications on the macro scale. Researchers have now unveiled a new CNT fiber that conducts heat and electricity like a metal wire, is very strong like carbon fiber, and is flexible like a textile thread.  Read More
