Small, self-controlled planes combine plant pathology and engineering
A Virginia Tech plant pathologist has developed autonomous unmanned aerial vehicles (UAVs) to detect airborne pathogens above agricultural fields.   view more (2007-06-14)

The Shifty Nature of Grains
In separate papers appearing in this week's Nature, researchers announce findings regarding the little-understood world of granular materials, systems of particles that can dictate the flow of avalanches, the quality of concrete and even the mixing of pharmaceuticals.   view more (2005-06-24)

Budding viral hijackers may co-opt cell machinery for the getaway
When retroviruses, like HIV, infect cells, they take over the cell's machinery to manufacture new copies of themselves. Research published this week in the top-tier open access journal, Journal of Biology, shows that to escape from cells, retroviruses may once again hijack cellular components, in... view more (2003-12-02)

Research overturns accepted notion of neutron's electrical properties
For two generations of physicists, it has been a standard belief that the neutron, an electrically neutral elementary particle and a primary component of an atom, actually carries a positive charge at its center and an offsetting negative charge at its outer edge.   view more (2007-09-18)

Big magnet ready to face the big questions of the universe
The largest superconducting magnet ever built has successfully been powered up to its operating conditions at the first attempt. Called the Barrel Toroid because of its shape, this magnet is a vital part of ATLAS, one of the major particle detectors being prepared to take data at CERN's Large... view more (2006-11-21)

Tech researchers help find new sub-atomic particle - shollis
Six Louisiana Tech researchers in the physics department played a role in discovering a new sub-atomic particle whose existence was announced this week.   view more (2007-06-18)

Auger Observatory links highest-energy cosmic rays with violent black holes
Scientists of the Pierre Auger Collaboration, which includes New York University Physics Professor Glennys R. Farrar, have concluded that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth.   view more (2007-11-09)

No sign of the Higgs
Are physicists spending billions on a wild goose chase? THE legendary particle that physicists thought explained why matter has mass, probably doesn`t exist. So say researchers who have spent a year analysing data from the LEP accelerator at the CERN nuclear physics lab near Geneva.... view more (2001-12-05)

Research breakthrough pinpoints aim of ion beams fired at cancer tumors
Nonsurgical cancer therapy that destroys tumors but leaves healthy surrounding tissue intact could be available at every hospital if research reported this week in the journal Nature eventually comes to fruition.   view more (2006-01-26)

Impact of a chemical component of diesel exhaust particles
A new study finds that exposure to a chemical component of diesel exhaust particles can compromise the ability of resistance arteries to regulate blood flow to bone marrow.   view more (2007-05-01)

CERN announces new start-up schedule for world's most powerful particle accelerator
Speaking at the 142nd session of the CERN Council today, the Organization's Director General Robert Aymar announced that the Large Hadron Collider (LHC) will start up in May 2008, taking the first steps towards studying physics at a new high-energy frontier.   view more (2007-06-25)

Nobel laureate Burton Richter to speak about future of particle physics
Particle physics is about to transform our thinking once again. Experiments of the last 15 years suggest new forms of matter, new forces of nature and perhaps even new dimensions of space and time. Pinning down the new ideas will require more data from larger and more expensive machines-at a time... view more (2007-02-16)

Airborne dust causes ripple effect on climate far away
When a small pebble drops into a serene pool of water, it causes a ripple in the water in every direction, even disturbing distant still waters.   view more (2007-01-30)

Scientists image a single HIV particle being born
A mapmaker and a mathematician may seem like an unlikely duo, but together they worked out a way to measure longitude - and kept millions of sailors from getting lost at sea.   view more (2008-05-27)

The Innovation Review: response from Research Councils UK
A government report examining the contribution that innovation makes to closing the nation's productivity gap has been welcomed by the UK's Research Councils. The DTI's Innovation Review, published today, recognises that the UK's Research Councils have significantly increased the rate of knowledge... view more (2003-12-17)

'Armored' bubbles can exist in stable non-spherical shapes
Researchers at Harvard University have demonstrated that gas bubbles can exist in stable non-spherical shapes without the application of external force.   view more (2005-12-15)

Electric sand findings could lead to better climate models
Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols.   view more (2008-01-08)

Last large piece of ATLAS detector lowered underground
Today, researchers in the U.S. ATLAS collaboration joined colleagues around the world to celebrate a pivotal landmark in the construction of the Large Hadron Collider (LHC) - the lowering of the final piece of the ATLAS particle detector into the underground collision hall at CERN in Geneva,... view more (2008-03-03)

Long the Fixation of Physicists Worldwide, a Tiny Particle Is Found
After decades of intensive effort by both experimental and theoretical physicists worldwide, a tiny particle with no charge, a very low mass and a lifetime much shorter than a nanosecond, dubbed the "axion," has now been detected by the University at Buffalo physicist who first suggested... view more (2006-12-07)

Fusing physics with medicine to fight cancer
Everyone's lives are touched by cancer - it is a disease that affects 1 in 3 of us throughout our lifetime. Future developments that lead to earlier diagnosis and more effective therapy lie in further successful collaboration between high energy physicists and the healthcare industry.   view more (2005-04-28)

MIT particles pave way for new bedside diagnostics
MIT researchers have created an inexpensive method to screen for millions of different biomolecules (DNA, proteins, etc.) in a single sample-a technology that could make possible the development of low-cost clinical bedside diagnostics.   view more (2007-03-09)

Nanopowder Consisting Of Identical Particles
High-quality nanopowders made of refractory ceramics are a rare and very expensive material. All known methods of their manufacturing face the same problems - scanty quantities, extensive variety of particle sizes and expensive production. Researchers from the town of Tomsk have invented and... view more (2004-03-26)

New technology for navigating without GPS
A new method for navigation at sea, independent of GPS, is being put forward in a dissertation from Linköping University.   view more (2005-03-12)

Dramatic Difference Discovered In Behaviour Of Matter And Antimatter
Today, August 2nd 2004, particle physicists from the UK and around the world working on the BABAR experiment at the Stanford Linear Accelerator Center (SLAC) in the USA, announced exciting new results demonstrating a dramatic difference in the behaviour of matter and antimatter. Their discovery may... view more (2004-08-02)

Caught in Flight
Chemists are very interested in unusual molecules that are made from atoms of a single element. For example, fullerenes ("buckyballs") and nanotubes, made of pure carbon, are generating a lot of excitement among materials scientists. If all were as it should be, the element phosphorus should be... view more (1999-11-24)
