Adaptive optics techniques used for the world's most powerful telescopes will be used to image the smallest processes in living systems, according to researchers in California.
In astronomy, adaptive optics fixes the blurring of deep-space images by correcting for the turbulence in Earth's atmosphere. These techniques have allowed the Keck telescopes in Hawaii to resolve deep-space objects with greater clarity than the Hubble Space Telescope.
Lawmakers working on next year’s federal finances have taken the ax to the James Webb Space Telescope. That’s right, NASA’s next-generation space telescope, the successor to Hubble and the space agency’s biggest post-shuttle project, may be killed.
The Extreme Light Infrastructure will be built in Eastern Europe

Who knew it would take so long to approve a project to build the world’s most powerful lasers? Lasers are awesome. But after reconciling some paltry funding issues, the European Commission finally approved the Extreme Light Infrastructure (ELI) project, which plans to build three superlasers by 2015.
A new type of endoscope with a super-small camera on its end could yield cheap, disposable scopes for peering inside your body. The camera is about the size of a grain of kosher salt, and its designers say it's the smallest camera ever.
It’s been a big week for the world of the small. In a new microscope breakthrough, researchers have figured out how to use a minuscule sheet of light to produce movies of living cells, revealing mitosis in action and illuminating cells' three-dimensional architecture with the greatest detail ever seen.
A new microscope combines a normal optical scope with a see-through microsphere superlens, beating the diffraction limit of light and shattering the limits of optical microscopes.
With the new method, there is theoretically no limit on how small an object researchers will be able to see. It could potentially see inside human cells and examine live viruses for the first time.
A $120 million Earth-based telescope using brand new adaptive optics just trumped Hubble's deep space image clarity three-fold, but such high tech optics aren't just reserved for high-dollar observatories. A breakthrough in deformable liquid mirror technology could drastically reduce the price associated with adaptive optics, making the best in high-tech telescopes more widely available.
When we tickle our artistic sides, playing with the varying fields of focus in our camera lenses can be a form of aesthetic expression. But for more practical uses -- say, filming a multi-layered scene like a concert where various subjects are at various depths -- it would be advantageous to capture the entire scene in perfect focus. A researcher in Toronto claims he's created an omni-focus camera that does exactly that.
In an image that the residents of Middle Earth might find unnerving, an international coalition of scientists have captured images of a two-year eclipse that are the first close-ups of such an event beyond our solar system.
Glaucoma is a tricky ailment to manage; rather than being a single disease, it's actually a cluster of diseases with various manifestations that, taken as a whole, are the second leading cause of blindness. But medical microtechnology firm Sensimed has engineered a sensor-laden contact lens that glaucoma sufferers can wear around-the-clock, helping doctors not only manage the potentially debilitating disease, but also learn more about how the mysterious condition works.
