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

NASA researchers are trying a 'scotch tape' design to build larger, more affordable X-ray ...

A team led by NASA's Maxim Markevitch is investigating the possibility of building bigger X-ray telescope mirrors – up to thirty times as large as today's – using a plastic tape coated with a reflective material and then, just like a roll of Scotch tape, tightly rolled on itself. By studying cosmic rays and distant galaxy clusters, such large and significantly cheaper mirrors would allow us to learn more about the birth and evolution of the universe.  Read More

Scientists have had success in tracking the passage of blood cells within the body, by lab...

Thanks to advances in stem cell therapy, it is now possible to use engineered white blood cells to fight diseases such as HIV within the human body. When such treatments are being developed, however, it can be difficult to track where the introduced cells travel within a patient’s system, and how many of them make it to their target. Now, thanks to research being carried out at the University of Edinburgh's Centre for Cardiovascular Science, those cells can be magnetically labeled.  Read More

Image of the shadow of a single ytterbium atom (Image: Griffith University)

A team of researchers at Griffith University has managed to stretch the capabilities of microscopy to its ultimate limit. Culminating a five-years effort, the scientists have obtained a digital image of the shadow cast by a single atom, in a development that might soon lead to important advances in scientific observations ranging from the very big to the very small.  Read More

Sample gigapixel image of the Seattle skyline captured by the prototype camera (Photo: Duk...

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
