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... view more (2008-03-14)

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... 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... view more (2005-06-10)

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)

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)

Protein simulation can be done three times as fast
Protein movement can be simulated three times as fast than had been thought possible up to now. Researchers from Groningen achieved the gain in speed by leaving out the calculations concerning hydrogen atoms. Meanwhile research groups around the world are adapting their simulation programs.   view more (2002-06-24)

Full 3-D image of nanocrystals' interior created by shining X-rays through them
A vital step towards the ultimate goal of being able to take 'photographs' of individual molecules in action has been achieved by an international team led by UCL (University College London) researchers at the London Centre for Nanotechnology.   view more (2006-07-06)

Researchers rely on Newton's interference for new experiment
Most people think of Sir Isaac Newton as the father of gravity. But for Lawrence Livermore National Laboratory physicist Henry Chapman and his colleagues, Newton's "dusty mirror" experiment served as a launching pad for them to keenly watch the X-ray induced explosion of microscopic... view more (2007-08-09)

Aggie physicists unite with Ivy League to develop anthrax detection method
Texas A&M University and Princeton University physicists have joined forces to perfect a powerful new weapon in the war on terrorism - a laser technique to identify deadly anthrax spores. Their results are published in the prestigious journal Science, due to hit newsstands tomorrow.   view more (2007-04-13)

By straddling twin molecules, Sandia physicist obtains unique view of their breakup
Imagine you are standing, John Wayne style, on the backs of two runaway horses pulling a stagecoach. You try to bring the horses to a stop but instead the harnesses break, the horses separate, and an unlucky passenger gets thrown from the stage.   view more (2006-01-20)

Enzymatic reaction rate surprises researchers
Enzymatic reactions, which are crucial in biological processes, can occur much faster than previously thought possible, as researchers at the biophysics department of the Faculty of Exact Sciences of the Vrije Universiteit Amsterdam have discovered. Their findings were published on line on 5 May in... view more (2003-05-07)
