Billions of insects join the “mile high club”
Entomologists have discovered that there are far more insects flying around above our heads than previously thought. Speaking at the Royal Entomological Society’s national meeting Entomology 2002, which will take place at Cardiff University on 12–13 September 2002, Dr Jason Chapman will say that in a typical summer month, around 3.5... view more...

Tiny lasers get a notch up
Tiny disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Unfortunately, a perfect disk will spray light out, not as a beam, but in all directions. view more (2009-01-23)
New view of the eye
Full colour images of the back of the eye are now better than ever thanks to research published today in the Institute of Physics journal Physiological Measurement. The new technique developed by Dr Ayyakkannu Manivannan and colleagues at the University of Aberdeen uses low-power coloured lasers to give a full colour picture that ophthalmologists... view more...

Physicists seek to keep next-gen colliders in 1 piece
Controlling huge electromagnetic forces that have the potential to destroy the next generation of particle accelerators is the subject of a new paper by a University of Manchester physicist. view more (2009-10-06)
Thermometer For Plasma
St. Petersburg researchers have designed an original thermometer for fast-moving electrons in thermonuclear reactors. The laser beam in this device is used to instantly determine the temperature of burning hot plasma, at frequencies required for precise diagnostics. This device is a further step forward to controlled nuclear fusion. The device... view more... (2003-09-05)
Lining up for a new atom smasher
The physicists are coming to Oxford for the ECFA/DESY Linear Collider Workshop, from 20-23 March. Here they will develop plans for two 10-km long particle accelerators which will be accurately aligned to fire beams of electrons and positrons (anti-electrons) at each other. When matter and antimatter collide, they disappear - annihilate - in a... view more... (1999-03-16)
Record-breaking luminosity boosts discovery potential at Fermilab's Tevatron collider
The record-breaking performance of the Tevatron collider at the Department of Energy's Fermi National Accelerator Laboratory is pushing the search for dark matter, supersymmetric particles and extra dimensions to new limits. view more (2006-03-07)
Physicists control the flip of electron spin in new study
Today's computers and other technological gizmos operate on electronic charges, but researchers predict that a new generation of smaller, faster, more efficient devices could be developed based on another scientific concept - electronic "spin.‚Ä? The problem, however, is that researchers have found it challenging to control or predict spin -... view more... (2005-05-27)
Einstein's relativity survives neutrino test
Physicists working to disprove "Lorentz invariance" -- Einstein's prediction that matter and massless particles will behave the same no matter how they're turned or how fast they go -- won't get that satisfaction from muon neutrinos, at least for the time being, says a consortium of scientists. view more (2008-10-16)
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)
Getting warmer -- Leeds research brings terahertz closer to everyday use
A collaboration between the Universities of Leeds and Harvard has turned the heat up on terahertz technology, bringing a handheld terahertz device a step closer to reality. view more (2008-03-31)
Porphyrin electron-transfer reactions observed at the molecular level
Researchers at Temple University have observed and documented electron transfer reactions on an electrode surface at the single molecule level for the first time, a discovery which could have future relevance to areas such as molecular electronics, electrochemistry, biology, catalysis, information storage, and solar energy conversion. view more (2007-08-03)
Exotic Materials Using Neptunium, Plutonium Provide Insight into Superconductivity
Physicists at Rutgers and Columbia universities have gained new insight into the origins of superconductivity - a property of metals where electrical resistance vanishes - by studying exotic chemical compounds that contain neptunium and plutonium. view more (2008-07-22)
Princeton researchers discover new type of laser
A Princeton-led team of researchers has discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices, and find applications in environmental monitoring and medical diagnostics. view more (2008-12-23)
Capturing cell protein production in action could help fight antibiotic resistance
The fight against antibiotic resistance could be aided by new 3D images of the final steps involved in manufacturing proteins in living cells, scientists reveal today in a letter to Nature. By refining a technique known as cryo-electron microscopy, researchers from Imperial College London and CNRS-Inserm-Strasbourg University have determined how... view more... (2004-02-25)
Physicists describe a new mechanism for metallic magnetism
Predicting the magnetic behavior of metallic compounds is a surprisingly difficult problem for theoretical physicists. view more (2005-08-26)
Researchers explain odd oxygen bonding under pressure
Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor. view more (2008-08-05)
New plasma transistor could create sharper displays
By integrating a solid-state electron emitter and a microcavity plasma device, researchers at the University of Illinois have created a plasma transistor that could be used to make lighter, less expensive and higher resolution flat-panel displays. view more (2009-02-05)
American-Made SRF Cavity Makes the Grade
The U.S. Department of Energy's (DOE's) Thomas Jefferson National Accelerator Facility marked a step forward in the field of advanced particle accelerator technology with the successful test of the first U.S.-built superconducting radiofrequency (SRF) niobium cavity to meet the exacting specifications of the proposed International Linear Collider... view more...

New on-off 'switch' triggers and reverses paralysis in animals with a beam of light
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. view more (2009-11-19)
