Quantum analog of Ulam's conjecture can guide molecules, reactions
Like navigating spacecraft through the solar system by means of gravity and small propulsive bursts, researchers can guide atoms, molecules and chemical reactions by utilizing the forces that bind nuclei and electrons into molecules (analogous to gravity) and by using light for propulsion. view more (2007-08-08)
Quantum physics pioneer honoured in Bristol
According to a current magazine advertisement, quantum physics is getting easier. It’s doubtful whether most of the population would agree with this. However, today (12 December) in Bristol, one of the pioneers of quantum physics, Noble prize-winner Paul Dirac, is being commemorated in two separate ceremonies. The first is in the Bishopston... view more... (2000-12-08)
Manipulating light on a chip for quantum technologies
A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements. view more (2009-06-09)
Physicists establish 'spooky' quantum communication
Physicists at the University of Michigan have coaxed two separate atoms to communicate with a sort of quantum intuition that Albert Einstein called "spooky." view more (2007-09-06)
Secrets from within planets pave way for cleaner energy
Research that has provided a deeper understanding into the centre of planets could also provide the way forward in the world's quest for cleaner energy. view more (2008-10-23)
World`s most powerful laser used as atom smasher - The Physics Congress 2002
Physicists at Glasgow University are using the world`s most powerful laser beam as an atom smasher to simulate conditions inside the Sun and to produce radioisotopes vital in medicine. Professor Ken Ledingham from the Department of Physics at Glasgow and his colleagues from Imperial College and the Rutherford Appleton Laboratory (RAL) are using... view more... (2002-03-26)
U of T physicists are first to 'squeeze' light to quantum limit
A team of University of Toronto physicists have demonstrated a new technique to squeeze light to the fundamental quantum limit, a finding that has potential applications for high-precision measurement, next-generation atomic clocks, novel quantum computing and our most fundamental understanding of the universe. view more (2009-01-07)
Microwave synthesis connects with the (quantum) dots
Materials researchers at the National Institute of Standards and Technology (NIST) have developed a simplified, low-cost process for producing high-quality, water-soluble "quantum dots" for biological research. view more (2008-06-13)
2 for 1: NIST design enables more cost-effective quantum key distribution
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a simpler and potentially lower-cost method for distributing strings of digits, or "keys," for use in quantum cryptography, the most secure method of transmitting data. view more (2008-05-30)
Quantum dot method rapidly identifies bacteria
A rapid method for detecting and identifying very small numbers of diverse bacteria, from anthrax to E. coli, has been developed by scientists from the National Cancer Institute (NCI) and National Institute of Standards and Technology (NIST). view more (2006-03-31)
Laser Blasts Viruses in Blood
A father-son research team working from separate laboratory benches across the country has discovered a new use for lasers - zapping viruses out of blood. The technique, which holds promise for disinfecting blood for transfusions, uses a low-power laser beam with a pulse lasting just fractions of a second. view more (2007-09-05)
Exploding Bubbles Detected by Laser Light
A revolutionary way of detecting the potentially dangerous gas bubbles in bore-holes that can lead to large explosions, is reported today in the Institute of Physics journal, Measurement Science and Technology. The new technique, developed by researchers at the University of Reading, could save the oil exploration industry millions of pounds by... view more... (2000-05-30)
Research measures movement of nanomaterials in simple model food chain
New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms. view more (2008-06-02)
Record breaking quantum encryption
The latest steps towards an uncrackable code have been taken by scientists in both Switzerland and the US, who have found novel ways of generating and transmitting "quantum keys" respectively. Both techniques are reported today, 12 July 2002, in New Journal of Physics, published jointly by the Institute of Physics and the German Physical... view more... (2002-07-10)
Laser Therapy Offers Alternative to Surgery for Liver Tumours
Research News in the British Journal of Surgery 11 September 2003: Laser light can be delivered in a controlled and predictable manner to destroy tumours. By inserting fibre optic cables through needles, doctors can direct the powerful laser light onto liver tumours - killing the cells and thus eliminating the need for major surgery. A review of... view more... (2003-09-11)
UCSB researchers develop drug delivery system using nanoparticles and lasers
Researchers at UC Santa Barbara have developed a new way to deliver drugs into cancer cells by exposing them briefly to a non-harmful laser. view more (2009-09-10)
Europe takes joint action on food-borne environmental pollutants in new expert network
The harmful effects of chemical contaminants in food are of major health concern in Europe today. However, a lack of integration of interdisciplinary activities, such as basic research and risk assessment, severely hampers the efforts to reach European excellence in this area. The individual research projects are also small in scale and not well... view more... (2004-03-22)
Slight Fluorescence Gives Hope For Recovery
Stomach ulcer not only aches, it also fluoresce. Russian researchers believe that the brighter the fluorescence is, the less chances the patient has to do without the operation. view more (2005-02-22)
Structuring polymers by laser
Microstructured polymer components are often used to direct light in optical devices. As an alternative to mechanical processes, laser light can also be used to produce the microscopic relief structures, and even to remove them without contact. With a flash of blue-green light, the show begins. Like a line of silent ballet dancers, long-chain... view more... (2004-05-14)
The search for new applications for laser light beams
Light can blind or distort colours, or confuse one with chiaroscuros. But it can have greater usefulness if its properties, characteristics, how it is created, etcetera are better understood. view more (2006-05-30)
