Astronomers have assembled a new, improved portrait of our deepest-ever view of the Univer...

NASA scientists have directed the Hubble Space Telescope to inspect a tiny patch of sky with an unusually long exposure time to obtain the deepest image of the sky ever obtained. The image, dubbed the Hubble Extreme Deep Field (XDF), reveals the faintest and most distant galaxies ever detected, shedding more light on the early history of the universe.  Read More

Lenses made of amorphous chalcogenide glass

Driving a car in the country at night can be a scary. The combination of poor visibility and animals or other hard to spot obstacles on the road poses an obvious threat to both the car and its occupants. Some luxury models now have the option of forward looking infrared (FLIR) night vision systems, so you can see the animal in time to swerve. Unfortunately these systems are pricey, even as an aftermarket add-on, but that may soon change through the work of researchers at the Fraunhofer Institute for Mechanics of Materials (IWM) in Freiburg, Germany. The researchers have invented a way of bringing down the cost of the infrared lenses in FLIR systems down by 70 percent - opening the way to cheap FLIR cameras for the mass market.  Read More

The photoactive plastic panel is 70 percent transparent to visible light

A UCLA team has developed a new type of solar cell that is nearly 70 percent transparent to the naked eye. The plastic cells, which use infrared instead of visible light, are also more economical than other types of cells because they are made by an inexpensive polymer solution process and nanowire technology, potentially paving the way for cheaper solar windows.  Read More

Researchers at MIT have developed a new type of photovoltaic cell made with carbon nanotubes that captures solar energy in the near-infrared region of the spectrum, which conventional silicon solar cells don’t. The new design means solar cell efficiency could be greatly increased, boosting the chances to make solar power a more popular source of energy.  Read More

A nanotube-infused paint invented at Rice University allows strain to be read using a near...

While wireless sensors for detecting the strain placed on bridges and buildings, such as the SenSpot, are easier and cheaper to install than embedded wired networks of sensors, they still need to be in physical contact with the structure being monitored. Researchers at Rice University have now developed a new type of paint, infused with carbon nanotubes, that could make strain detection of materials in buildings, bridges and aircraft possible without actually touching the material.  Read More

The Satechi WTR-A lets you control your Canon DSLR from a distance of up to 50 ft (15 m), ...

With the introduction of smartphone apps like Triggertrap and ioShutter, which allow you to control your DSLR from your phone, you might wonder why anyone would still buy a dedicated remote unit ... until that is, you miss a once-in-a-lifetime shot because you needed the phone for something else at the crucial moment. Sometimes simple is better. The Satechi WTR-A is a budget wireless timer remote for Canon DSLRs.  Read More

Upon completion, the E-ELT is expected to be the largest optical telescope in the world

The European Southern Observatory (ESO) council met on Monday in Garching, Germany and approved the European Extremely Large Telescope (E-ELT) program, pending the confirmation of ad referendum votes from the authorities of four member states before the next council meeting. Assuming all goes according to plan, the E-ELT is expected to begin operation early in the next decade.  Read More

Foodies who've ever dreamed of having superhero-style vision that could analyze what they are about to eat should keep an eye on the upcoming Sensor+Trade fair in Nuremberg. Scientists from the Fraunhofer Institute of Photonic Microsystems (IPMS) will be exhibiting a tiny prototype spectrometer that can measure factors such as water and protein level in foods, meaning you won't make the mistake of buying fruit that looks good on the outside but is rotten at its core.  Read More

NASA's Spitzer Space Telescope has detected infrared light emanating from 55 Cancri e, a dark, blazing-hot planet only twice the size of Earth and eight times as heavy. This marks the first time that light has been detected from a planet of such a small size, and the find is telling astrophysicists where to look in their search for signs of life on planets beyond our own.  Read More

Rattlesnakes, beware! The next time you spot a succulent-looking squirrel, it might actually be a cold-hearted robot. More specifically, it might be a “robosquirrel,” created by UC Davis professor of mechanical and aerospace engineering Sanjay Joshi. He built the robot squirrels as part of a study on rattlesnake behavior – a study which yielded some interesting results.  Read More
