Fibre Laser Points To Woven 3-D Displays

A fibre that can emit light along its length in any direction may herald flexible 3-D displays and medical tools that activate therapeutic compounds with bursts of light. Most light...

Make Gardening Fun - Control Weeds Using CO2 Lasers

The laser beam can be used to selectively fight weeds in an early growth stage. This is the result of a current research project between the Laser Zentrum Hannover (LZH) and the Biosystems and...

Ultra-high-resolution Additive Manufacturing Laser Printer Breaks Speed-Records at Vienna University of Technology

Printing three dimensional objects with incredibly fine details is now possible using “two-photon lithography”. With this technology, tiny structures on a nanometer scale can be fabricated....

Solar Probe Must Survive ‘Hellish’ Conditions

Engineers are designing a NASA probe to take a close-up look at the sun while enduring blowtorch temperatures, supersonic solar particles, and intense radiation. The planned Solar Probe...

Smartphones With 1,000 Times More Speed

Researchers have demonstrated a physical basis for terahertz bandwidth that could make smartphones and laptops 1,000 times faster than current communication technologies. Many products...

‘Lens’ Zooms in on Brightest, Distant Galaxy

A natural “zoom lens” in space offers a uniquely close-up look at the brightest gravitationally magnified galaxy yet discovered. Click here to view the images captured The imagery...

Phase Transition in Trillionth-of-a-Second Intervals

Ultrafast “sonograms” are revealing the dynamic changes that take place as materials undergo phase transitions. An international team of physicists developed the new technique that can...

Tsunami Mapped with Laser Scanners

The 2011 Tohoku tsunami was Japan’s deadliest in more than 100 years.  Despite an extraordinary level of preparedness by the Japanese, the tsunami caused more than 90 percent of the almost...

Scientists and Physicists Inspired by Curly Leaves Develop New Technique for Shaping Thin Gel Sheets

Inspired by nature’s ability to shape a petal, and building on simple techniques used in photolithography and printing, researchers at the University of Massachusetts Amherst have developed a...

Metamaterials May Advance with new Femtosecond Laser Technique

Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways. Working at a scale...

NIST Measurements May Help Optimise Organic Solar Cells

Organic solar cells may be a step closer to market because of measurements taken at the National Institute of Standards and Technology (NIST) and the U.S. Naval Research Laboratory (NRL), where...

'Star Comb' Joins Quest for Earthlike Planets

If there is life on other planets, a laser frequency comb developed at the National Institute of Standards and Technology (NIST) may help find it. Such a comb—a tool for precisely measuring...

IBM "Holey Optochip" First to Transfer One Trillion Bits of Information per Second

IBM scientists today reported on a prototype optical chipset, dubbed “Holey Optochip”, that is the first parallel optical transceiver to transfer one trillion bits – one terabit – of information...

Camera Captures First Ever Images of Atoms Moving in a Molecule

Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule. Key to the experiment is the researchers’ use of the energy of a...

Spectroscopic Imaging Reveals Early Changes Leading to Breast Tumours

Purdue University researchers have created a new imaging technology that reveals subtle changes in breast tissue, representing a potential tool to determine a woman's risk of developing breast...

Tevatron Experiments Report Latest Results in Search for Higgs Boson

Using different search techniques, Tevatron physicists see hints of Higgs boson sighting consistent with those from LHC. New measurements announced today by scientists from the CDF and...

ASU Mars Camera Celebrates a Decade of Discoveries

Ten years ago, on Feb. 19, 2002, the Thermal Emission Imaging System (THEMIS), a multi-band camera on NASA's Mars Odyssey orbiter, began scientific operations at the Red Planet. Since then the...

Finding Distant Explosives With Laser Beams

A new method uses laser light to detect chemicals inside a container from a distance of more than 100 meters. Specific substances scatter laser light in a very specific way. This is the...

Two Molecules Communicate Via Single Photons

Scientists realise one of the most elementary and oldest “gedanken” experiments in modern physics, namely, excitation of a single molecule with a single photon. This paves the way for further...

Lens Produces Hours of Scientific Work in Seconds

A new form of microscope which can produce results in seconds rather than hours- dramatically speeding up the process of drug development- is being developed at Strathclyde. Scientists are...
