JILA solves problem of quantum dot 'blinking'
Quantum dots-tiny, intense, tunable sources of colorful light-are illuminating new opportunities in biomedical research, cryptography and other fields. But these semiconductor nanocrystals also have a secret problem, a kind of nervous tic. They mysteriously tend to "blink" on and off like Christmas tree lights, which can reduce their... view more...

Funding to develop tomorrow's technology
The University of Sussex is the only university to receive two awards from a new multi-million-pound government fund that aims to revolutionise scientific research and innovation. Two initiatives at Sussex are to be supported by the Basic Technology Research Programme, which is being managed by the Engineering and Physical Sciences Research... view more... (2002-02-26)
Oregon physicists don't flip spin but find possible electron switch
University of Oregon researchers trying to flip the spin of electrons with laser bursts lasting picoseconds (a trillionth of a second) instead found a way to manipulate and control the spin -- knowledge that may prove useful in a variety of new materials and technologies. view more (2008-05-28)
Quantum hall effect observed at room temperature
Using the highest magnetic fields in the world, an international team of researchers has observed the quantum Hall effect - a much studied phenomenon of the quantum world - at room temperature. view more (2007-02-16)
Researchers putting a freeze on oscillator vibrations
University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical vibrations to a near standstill. view more (2009-06-18)
Physicists offer new theory for iron compounds
An international team of physicists from the United States and China this week offered a new theory to both explain and predict the complex quantum behavior of a new class of high-temperature superconductors. view more (2009-03-13)
Software advance helps computers act logically
Computers just respond to commands, never "thinking" about the consequences. A new software language, however, promises to enable computers to reason much more precisely and thus better reflect subtleties intended by commands of human operators. view more (2005-06-17)
Ethnic Minorities Make more Educational & Serious Use of Computers Than Their White Neighbours
New research into disadvantaged neighbourhoods by the Universities of Warwick and Leeds for the Department for Education and Skills has found that - although in general ethnic minorities had less access to home computing and the internet than their white neighbours, they tended to use their home computers much more often than white people for... view more...

Computers in the classrooom: girls lose out in the boy zone
Boys dominate computers in the classroom, and young girls still see the computer as predominantly a 'male preserve' according to research presented today, Tuesday 15 December, to The British Psychological Society's London Conference, held at the Institute of Education, by psychologists Dr Helen Fitzpatrick (Strathclyde University) and Dr Margaret... view more...

Scientists discover new method of observing interactions in nanoscale systems
Scientists have used new optical technologies to observe interactions in nanoscale systems that Heisenberg's uncertainty principle usually would prohibit, according to a study published Jan. 17 in the journal Nature. view more (2008-01-17)
Connect the Quantum Dots
By using the unique photophysical properties of quantum dots, researchers Drs. Francisco Raymo, Ibrahim Yildiz, and Massimilliano Tomasulo were able to identify operating principles to probe molecular recognition events with luminescence measurements. view more (2006-07-19)
Physics World Digest: August 2002 edition
Physicists see eye to eye with opthamologists Glaucoma is one of the leading causes of blindness in adults - yet over half of us who have the disease do not realise that we are suffering from the condition. While the disease can be treated if caught soon enough, early diagnosis relies on regular screening programmes that can be expensive and... view more... (2002-08-01)
Single spinning nuclei in diamond offer a stable quantum computing building block
Surmounting several distinct hurdles to quantum computing, physicists at Harvard University have found that individual carbon-13 atoms in a diamond lattice can be manipulated with extraordinary precision to create stable quantum mechanical memory and a small quantum processor, also known as a quantum register, operating at room temperature. view more (2007-06-01)
Quantum dance: Discovery led by Princeton researchers could revolutionize computing
An international team of scientists, led by a Princeton University group, has observed an exciting and strange behavior in electrons' spin within a new material that could be harnessed to transform computing and electronics. view more (2009-02-19)
Tandem ions may lead the way to better atomic clocks
Physicists at the Commerce Department's National Institute of Standards and Technology (NIST) have used the natural oscillations of two different types of charged atoms, or ions, confined together in a single trap, to produce the "ticks" that may power a future atomic clock. view more (2005-07-29)
Quantum dot recipe may lead to cheaper solar panels
Rice University scientists today revealed a breakthrough method for producing molecular specks of semiconductors called quantum dots, a discovery that could clear the way for better, cheaper solar energy panels. view more (2007-05-03)
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)
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)
Virtual Reality in the Theatre
As all cinema-goers have noticed, the use of computers in film-making has had considerable impact, helping to create special effects that would have been impossible just a decade ago. Now, thanks to the work of a visiting academic at the University of Kent at Canterbury (UKC), computers are being used to add a whole new dimension to theatre... view more... (2000-03-07)
