From Earth's perspective, on June 5 and 6, Venus will pass across the face of the Sun. By observing the tiny fraction of sunlight that passes through Venus's atmosphere using the Hubble Space Telescope, it is hoped that the planet's atmospheric makeup can be determined. Though we already know the nature of Venus's atmosphere, it is hoped the event will help astronomers hone techniques, already in use, that may one day help to identify Earth-like planets in far-away solar systems. The catch? Hubble cannot observe the Sun directly. Instead it will look at the Moon to observe reflected light.  Read More

One of OriginOil's 75 GPM (300 LPM) flocculation units

OriginOil and Algasol, two companies working to develop algae into renewable fuel, have announced a collaboration on growth and harvest technology. The companies hope the partnership will help them reduce cost and improve performance, therefore increasing commercial prospects for algae as fuel source. Harvesting algae is one of the main cost drivers associated with this type of raw material. Algae are microscopic and live in suspension on liquid. When the time comes to harvesting it, the water/algae ratio can be as high as 1,000/1. In order to make it suitable for commercial applications, that ratio needs to be reduced to around 10/1.  Read More

A new X-ray microscope at Brookhaven National Laboratory is being used to create unparalleled high-resolution 3D images of the inner structure of materials. Using techniques similar to taking a very small-scale medical CAT (computer-assisted tomography) scan, the full field transmission x-ray microscope (TXM) enables scientists to directly observe structures spanning 25 nanometers - three thousand times smaller than a red blood cell - by splicing together thousands of images into a single 3D X-ray image with "greater speed and precision than ever before." This capability is expected to power rapid advances in many fields, including energy research, environmental sciences, biology, and national defense.  Read More

A cut-away view of the LSST camera, with a person for scale

Although the pixel count for consumer cameras continues to rise, they will all pale in comparison to the 3,200-megapixel Large Synoptic Survey Telescope (LSST) camera. Although the enormous astronomical camera has yet to be built, last week the U.S. Department of Energy gave its approval for the project to proceed to the next phase of development. This means that a detailed engineering design can begin, along with a production schedule and budget. If everything goes according to plan, construction on what will be the world’s largest digital camera should begin in 2014.  Read More

If you’ve ever watched a cephalopod such as a squid changing color, then you’ll know that it’s a pretty amazing process – they can instantly change the appearance of their skin from dark to light and back again, or even create pulsating bands of color that travel across it. They are able to do this thanks to muscles that manipulate the pigmentation of their skin. Now, scientists from the University of Bristol have succeeded in creating artificial muscles and cells, that might someday allow for the same sort of color changes in smart clothing that can camouflage itself against different backgrounds.  Read More

A nanowire sporting tendrils of nanoparticles, which greatly add to its surface area

Higher-density batteries, more efficient thin-film solar cells, and better catalysts may all soon be possible, thanks to a new technique that allows nanowires to be “decorated” with nanoparticles. Using the novel technology, scientists from Stanford University have been able to festoon the outside surfaces of nanowires with intricate chains of metal oxide or noble metal nanoparticles, thereby drastically boosting the effective surface area of the nanowires. Other researchers have previously tried to achieve the same end result, but apparently never with such success.  Read More

Researchers have designed coupled lasers that act as general-purpose optical logic gates

High hopes have been maintained for decades concerning optical logic, optical switching matrices (e.g. for communications), and optical computing. The missing link in actualizing this promise is a practical circuit element that allows one light to be turned on or off purely by application of another light to the device - rather like voltage on the control gate of a field effect transistor. This missing link has now been developed through a novel application of the complex behavior exhibited by coupled lasers.  Read More

By sandwiching a layer of ferric chloride molecules between two sheets of graphene (pictur...

Currently, virtually all touchscreen displays found in our electronic devices rely on a coating of indium tin oxide (ITO). It is used because of its electrical conductivity, its optical transparency, and the ease with which it can be deposited onto a display as a thin film. Using graphene, researchers at the University of Exeter have developed a viable alternative to increasingly expensive ITO that they claim is the “most transparent, lightweight and flexible material ever for conducting electricity.”  Read More

Majorana fermions might be the sole component of the dark matter in our Universe (Photo:

Physicists at the Delft University of Technology, Netherlands, have achieved a milestone that might soon revolutionize the world of quantum computing, quantum physics, and perhaps shed new light on the mystery of the dark matter in our universe. Experimenting with nanoelectronics, a group led by Prof. Leo Kouwenhoven has succeeded in detecting the elusive Majorana fermion in the laboratory, without the need for a particle accelerator.  Read More

Researchers at Purdue University in the U.S. have developed a new method of harvesting vast amounts of energy from waste heat. Using glass fibers dipped in a solution containing nanocrystals of lead telluride, the team led by Dr. Yue Wu is engineering a highly flexible thermoelectric system that generates electricity by gathering heat from water pipes and engine components.  Read More
