Researchers advance ultra-thin flat lens to capture perfect colors

By - February 23, 2015 2 Pictures
Ultra-thin flat lenses suitable for photography are one step closer after a team of researchers at Harvard University made a major leap forward with its prototype wafer-thin flat lens. The new lens builds on the original prototype, which we first heard about in 2012, by using an achromatic metasurface to focus different wavelengths of light at the same point. Read More

Infrared imaging shows Trifid Nebula in a new light

By - February 8, 2015 4 Pictures
The European Southern Observatory's (ESO) VISTA survey telescope has revealed a beautiful new aspect of the Trifid Nebula, a star formation area that sits around 5,200 light years away from Earth, in the direction of the galactic center. By observing and imaging the nebula in infrared light, astronomers can look through the dust-filled, central parts of the Milky Way to expose new objects. Read More

ESA successfully tests FLEX instrument, designed to create maps of photosynthetic activity

By - February 4, 2015
The European Space Agency (ESA) has successfully tested its Fluorescence Explorer mission (FLEX), which is vying for a spot on the organisation’s eight Earth Explorer satellite. The mission, which aims to create global maps of photosynthetic activity, will allow for the identification of vegetation suffering degrees of stress that simply aren’t visible to the human eye. It has the potential to significantly further our understanding of the global carbon cycle, and could have an impact on agricultural management. Read More

New maritime monitoring system would draw on existing satellites

By - February 2, 2015
According to a scientist from the University of Leicester in the UK, the search for missing ships and sea-crossing aircraft – such as Malaysia Airlines flight MH370 – would be much easier if existing satellites were simply used differently. Dr. Nigel Bannister is developing a system in which spacecraft that already keep an eye on the land could also turn their attention to the sea. Read More

"SCAPE" microscope offers faster and simpler imaging of freely moving samples

By - January 20, 2015 2 Pictures
Elizabeth Hillman, associate professor of biomedical engineering at Columbia University Medical Center (CUMC), has developed a new 3D microscope prototype dubbed "SCAPE" (Swept Confocally Aligned Planar Excitation Microscopy), which requires no mounting of samples or other special preparation, and is capable of imaging freely moving living samples at speeds 10 to 100 times faster than current laser-scanning microscopes.

World's fastest 2D camera captures 100 billion frames per second

By - December 3, 2014
Researchers at Washington University in St.Louis have built what they claim is the world's fastest 2D receive-only camera, which is able to capture images at a rate of up to 100 billion frames per second. Using a technique called Compressed Ultrafast Photography (CUP), the researchers have so far taken photographs of a number of properties of light propagation and behavior that are already pushing the dimensional limits of fundamental physics.
