Blast overpressure is generated from the firing of weapons and may cause brain injury
The brain may be injured by the noise, which is produced when, for example, an anti-tank weapon (Bazooka, Karl Gustav) or a howitzer (Haubits) is fired. view more (2009-01-29)
Solving a subatomic shell game
Physicists at Michigan Technological University have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 elements known as rare earths. view more (2009-03-24)
Nuclear physicists examine oxygen's limits
Physicists at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University have made a unique measurement of an exotic oxygen nucleus, leading scientists one step closer to deciphering the behavior of the element at its limits of existence. view more (2007-09-14)
Are humans still evolving? Absolutely, says a new analysis of a long-term survey of human health
Although advances in medical care have improved standards of living over time, humans aren't entirely sheltered from the forces of natural selection, a new study shows. view more (2009-10-20)
Atoms looser than expected
All the atoms in the universe just got looser, at least in the eyes of humans. No, the laws of physics didn't change overnight, but our knowledge of how strong atoms are held together did have to be readjusted a bit in light of a new experiment conducted at Harvard University. view more (2006-08-16)
Earthquakes Happen at Full Moon
Russian physicists have found that flashes of neutron radiation from the Earth surface are bound to increasing in seismic activity. They believe that this phenomenon can be used as a novel kind of earthquake foreboding. The researchers of the Department of Cosmic Radiation of the Research Institute of Nuclear Physics at Moscow State University... view more... (2001-02-02)
International alliance to unlock secrets of Egyptian mummies
Two world-renowned teams of experts on Egyptian mummies have joined forces in an international effort to better understand disease and its treatment in ancient Egypt. view more (2005-05-18)
Friction force differences could offer a new means for sorting and assembling nanotubes
Nanotubes and nanowires are promising building blocks for future integrated nanoelectronic and photonic circuits, nanosensors, interconnects and electro-mechanical nanodevices. But some fundamental issues remain to be resolved - among them, how to position and manipulate the tiny tubes. view more (2009-09-16)
Environmental Manufacturing Could Stem UK Manufacturing Slump
Professor Sir Kumar Bhattacharyya , one of the UK's Leading Manufacturing experts, will, on Tuesday 20th April, tell an international conference at the University of Warwick that environmentally aware manufacturing is the one remaining thing that can stem the quarter century long slump in volume manufacturing in the UK and Europe. Professor Sir... view more... (2004-04-19)
Stormy Days Ahead for Coral Reefs
The increasing violence of storms under global climate change will have major effects on coral reefs - and has important implications for their future management. view more (2006-11-29)
Why tyres grip the road - New theory dispenses with long tests
What do Formula One racing tyres have in common with fly`s feet? This apparently bizarre question can be answered with the aid of physics: They are both soft and supple and exude a more or less sticky liquid. In this way, irregularities on the asphalt or - in the case of the fly - on the window pane are filled in. The area of contact becomes... view more... (2002-06-10)
Inexperienced Electric Guitarists at Risk
An innovative study at the Robens Centre for Health Ergonomics at the University of Surrey has found that young and inexperienced electric guitar players may be at particular risk of developing musculoskeletal problems, such as RSI. The research, undertaken by ergonomics student and chartered physiotherapist Kathy Lewis, involved assessing the... view more... (2002-10-09)
Invading black holes explain cosmic flashes
Black holes are invading stars, providing a radical explanation to bright flashes in the universe that are one of the biggest mysteries in astronomy today. view more (2009-09-21)
Nanoscopic static electricity generates chiral patterns
In the tiny world of amino acids and proteins and in the helical shape of DNA, a biological phenomenon abounds. view more (2009-02-02)
New research reveals how cranberry products prevent urinary tract infections
Chemicals present in cranberries-and not the acidity of cranberry juice, as previously thought-prevent infection-causing bacteria from attaching to the cells that line the urinary tract, as documented in a report published in Journal of Medicinal Food, a peer-reviewed journal published by Mary Ann Liebert, Inc. view more (2009-03-10)
Study of coastal disasters yields surprising findings, arresting images
Two of the world's worst natural disasters in recent years stemmed from different causes on opposite sides of the globe, but actually had much in common, according to researchers who are part of a large National Science Foundation-funded research initiative that has been studying both the Indian Ocean Tsunami of 2004 and the Hurricane Katrina of... view more...

The day LISA Pathfinder hung in the balance
At the core of ESA's LISA Pathfinder mission sit two small hearts. Each is a cube, just 5 centimetres across. Together they will allow LISA Pathfinder to lay the foundations for future space-based measurements that investigate the very core of Einstein's General Relativity. view more (2006-10-12)
Size matters: Friction, adhesion change on atomic level
Physicists have a pretty good idea of what to expect when friction and adhesion occur in the visible world. You jam on the brakes, for instance, and your tires and the highway interact to stop your car. You glue two pieces of wood together, and they stick. view more (2005-06-30)
Evolution of skull and mandible shape in cats
In a new study published in the online-open access journal PLoS ONE, Per Christiansen at the Zoological Museum in Copenhagen, Denmark, reports the finding that the evolution of skull and mandible shape in sabercats and modern cats were governed by different selective forces, and the two groups evolved very different adaptations to killing. view more (2008-07-30)
Stretching bone marrow stem cells pushes them towards becoming blood vessel
When stretched, a type of adult stem cell taken from bone marrow can be nudged towards becoming the type of tissue found in blood vessels, according to a new study by bioengineers at the University of California, Berkeley. view more (2006-10-24)
