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

The military use of radar has always had a yin-yang dynamic – as new forms of radar are developed, so too are new ways to jam them. A team of physicists at the University of Rochester has discovered how to defeat the latest active radar jamming methods by taking advantage of the quantum properties of photons. While this new anti-jamming technology cannot remove the false information, it provides an immediate alert that false information is being received.  Read More

One of the new chips was used to non-destructively image a bullet and a knife blade hidden...

Terahertz technology (or T-Ray, for short), sounds like something out of a science fiction movie. It utilizes high-frequency terahertz waves – which are located between microwaves and far-infrared radiation on the electromagnetic spectrum – to see through solid matter without the harmful ionizing radiation of X-rays. Although T-Ray devices have yet to become compact and affordable, that could soon change thanks to new silicon microchips developed at the California Institute of Technology.  Read More

An aurora appearing in the night sky at the Kjell Henriksen Observatory in Svalbard, Norwa...

Even those of us not lucky enough to have witnessed them in person will likely have marveled at photos of the stunning auroras caused by high energy particles from the Sun colliding with atoms in the Earth’s atmosphere. A team of space-weather researchers has now developed a new camera called NORUSCA II that has produced the first-ever hyperspectral images of the aurora borealis (or northern lights) and may have uncovered a previously unknown atmospheric phenomenon.  Read More

Astrophoto of M31, the Andromeda Galaxy, taken with an 85mm (3.35 in) diameter Takahashi a...

While nearly everyone enjoys a good astrophoto, the precision with which the astrograph (the telescope taking the photograph) must follow the stars is not widely appreciated. To take a good astrophoto of any but the brightest objects requires following their motion through the sky accurately. There are a number of approaches toward addressing this problem in the digital era. Perhaps the best option has now been enabled by Innovations Foresight's new ON-Axis Guider (ONAG).  Read More

The scanner being used to check for an ear infection

Although there are various efforts under way to create a working Star Trek-like medical tricorder, such a device isn’t available for general use just yet. In the meantime, however, doctor’s offices may soon be equipped a piece of equipment that wouldn’t look at all out of place in the sick bay of the Enterprise. Developed by engineers from the University of Illinois at Urbana-Champaign, it’s a hand-held scanning device that provides real-time three-dimensional images of the insides of patients’ bodies.  Read More

Zoomed-in image of barred spiral galaxy NGC 1365, around 60 million light years from Earth...

The Dark Energy Camera (DEC) has captured an initial batch of images as part of an ongoing quest to afford scientists with a better understanding of dark energy. The images were taken by the 570-megapixel behemoth from its location within the Chilean Andes on September 12 while undergoing a series of tests. Scientists hope it may soon help answer one of the biggest mysteries in physics: why the expansion of the universe is speeding up.  Read More

New video software may be able to tell if someone is intoxicated, by scanning their face (...

People who are inebriated in public places (such as airliners or malls) can definitely create problems. Sometimes, though, it’s difficult to tell if someone really is under the influence. Instead of making every “jolly”-looking person take a breathalyzer test, Greek researchers are suggesting something less intrusive – video software that can spot drunks by analyzing their faces.  Read More

A new ultrathin, flat lens focuses light without imparting the optical distortions of conv...

The miniaturization of electronics, in particular the electronic sensors on which digital images are captured, has seen digital cameras shrink to such a degree that they are now standard equipment on mobile phones. The main thing holding back further downsizing is the lens through which the light is focused onto said image sensor. A team of applied physicists from Harvard University has now overcome this roadblock by creating a lens that, at just 60 nanometers thick, is effectively two-dimensional. Not only that, the ultrathin lens focuses light without the distortions seen in conventional lenses.  Read More

NCTech's iSTAR is designed to deliver high resolution 360-degree image capture

Scottish company NCTech has created an all in one 50 megapixel camera that's designed to make 360 panoramic photography quick and easy to achieve. A flexible system in terms of use, the iSTAR combines ingenuity with an ability to generate high quality and information rich results.  Read More
