Catching the wave — Researchers measure very short laser pulses
Scientists have perfected a technique for very accurately measuring and controlling the electromagnetic waves within some of the shortest laser pulses ever made, says new research published today. view more (2006-12-04)
Ultra-fast, ultra-intense laser has clean-cut advantage
Many people equate lasers with a sci-fi battle in a galaxy far, far away or, closer to home, with grocery store scanners and compact disc players. view more (2008-03-14)
Laser Surgery Probe Targets Individual Cancer Cells
Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases. view more (2008-06-25)
Scientists create metal that pumps liquid uphill
In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a simple slab of metal that lifts liquid using the same principle-but does so at a speed that would make nature envious. view more (2009-06-03)
Ultra-Intense Laser Blast Creates True 'Black Metal'
"Black gold" is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black. view more (2006-11-22)
Regular Light Bulbs Made Super-Efficient with Ultra-Fast Laser
An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. view more (2009-06-01)
Nano technique allows precise injection of living cells
Specialized pulsed lasers have been used to inject individual cells with a variety of materials, but little is known about how this type of injection might affect living cells. view more (2007-06-18)
Supercontinuum generation and soliton dynamics milestone achieved
A research team led by Fetah Benabid, University of Bath, has observed for the first time the simultaneous emission of two resonant dispersive waves by optical solitons (waves that maintain their shape while traveling at constant speeds). view more (2008-11-21)
Fine-tuning lasers to destroy blood-borne diseases like AIDS
Physicists in Arizona State University have designed a revolutionary laser technique which can destroy viruses and bacteria such as AIDS without damaging human cells and may also help reduce the spread of hospital infections such as MRSA. view more (2007-11-01)
Vibrations key to efficiency of green fluorescent protein
University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel Prize in Physiology or Medicine. view more (2009-11-12)
A sub-femtosecond stop watch for 'photon finish' races
Using a system that can compare the travel times of two photons with sub-femtosecond precision, scientists at the Joint Quantum Institute (a partnership of the National Institute of Standards and Technology (NIST) and the University of Maryland) and Georgetown University have found a remarkably large difference in the time it takes photons to pass... view more...

Laser blasts will reveal structures and dynamics of molecules in the fastest events in nature
A new £2 million Research Centre at the University of York will provide unprecedented information on how molecules change, helping scientists understand the structure and dynamics of liquids, proteins and even our DNA. The York Centre for Laser Spectroscopy and Photochemistry opened today (29 October 2003), will use ultra-short laser light... view more... (2003-10-27)
The short-term memory of water
Researchers of the Max-Born-Institute and the University of Toronto find extremely fast fluctuations in liquid water - Publication in Nature. view more (2005-03-07)
Pitt researchers see electron waves in motion for first time
Both the ancient art of stained glass and the cutting-edge field of plasmonics rely on the oscillation of electrons in nanosized metal particles. When light shines on such particles, it excites the electromagnetic fields on the metal's surface, known as "surface plasmons," and causes its electrons to oscillate in waves-producing the rich... view more...

Purdue 'milestone' a step toward advanced sensors, communications
Engineers at Purdue University have shown how to finely control the spectral properties of ultrafast light pulses, a step toward creating advanced sensors, more powerful communications technologies and more precise laboratory instruments. view more (2007-08-02)
Ready to go: mobile terahertz devices
Terahertz waves, which until now have barely found their way out of the laboratory, could soon be in use as a versatile tool. Researchers have mobilized the transmitting and receiving devices so that they can be used anywhere with ease. view more (2008-04-09)
U of T team heats up gold to surprising effect: it gets harder not softer
Common sense tells us that when you heat something up it gets softer, but a team of researchers, led by University of Toronto chemistry and physics professor R.J. Dwayne Miller, has demonstrated the exact opposite. view more (2009-01-23)
Ultrafast laser spectrometer measures heat flow through molecules
Global warming isn't the only heat scientists are feeling. Another area in which heat flow is becoming crucial is the field of molecular electronics, where long-chain molecules attached to tiny electrodes are used to transport and switch electrons. view more (2007-08-10)
Results with newer bladeless LASIK equivalent to standard microkeratome LASIK
A Mayo Clinic study comparing femtosecond (bladeless) and mechanical microkeratome LASIK surgeries has found equal results from both types six months post-surgery, using a variety of vision and eye health measurements. view more (2006-05-04)
Laser pulses control single electrons in complex molecules
Predatory fish are well aware of the problem: In a swarm of small fish it is hard to isolate prey. A similar situation can be found in the microcosm of atoms and molecules, whose behavior is influenced by "swarms" of electrons. view more (2009-09-02)
