Saving teeth by using periodontal ligament regeneration
Teeth may fall out as a result of inflammation and subsequent destruction of the tissues supporting the teeth. Dutch researcher Agnes Berendsen has investigated a possible solution to this problem. view more (2008-06-05)
The Lovell Telescope presents a new face to the universe
After many months of unseen work, the University of Manchester`s giant Lovell Telescope at the Jodrell Bank Observatory in Cheshire is again scanning the skies with a brand new, pristine white, surface. After two summers of work, the installation and painting of the new galvanised steel surface has been completed so that the telescope now presents... view more... (2002-11-04)
NIST imaging system maps nanomechanical properties
The National Institute of Standards and Technology (NIST) has developed an imaging system that quickly maps the mechanical properties of materials-how stiff or stretchy they are, for example-at scales on the order of billionths of a meter. view more (2007-12-13)
The lower atmosphere of Pluto revealed
Using ESO's Very Large Telescope, astronomers have gained valuable new insights about the atmosphere of the dwarf planet Pluto. The scientists found unexpectedly large amounts of methane in the atmosphere, and also discovered that the atmosphere is hotter than the surface by about 40 degrees, although it still only reaches a frigid minus 180... view more...

Possible evidence found for Beagle 2 location
The news that Beagle 2 may have been spotted on the surface of Mars in the immediate vicinity of where it was expected to land was welcomed by the European Space Agency. view more (2005-12-22)
ESA takes a new look at the Moon
Thirty years after Apollo 16`s lunar module, Orion, landed at the western edge of the Descartes Mountains on 21 April 1972, there is still much that we don`t know about the Moon. For instance, how was it created? And what role did it play in the formation and evolution of Earth? We may be closer to answering those, and many other questions,... view more... (2002-04-23)
Short Bursts of Exercise 'Best for Health'
If sticking to a 30-minute routine of exercising each day seems too daunting, researchers from the University of Ulster say three 10-minute sessions, spread out over the day, yields similar health and psychological benefits. Currently, the US surgeon general recommends adults do their best to get off the couch and exercise for about 30 minutes... view more... (2002-09-18)
UW paper in Science shows how some solids mimic liquids on nanoscale
A University of Waterloo physics and astronomy research team, in a paper to be published Friday in Science Magazine, shows how some solids behave like liquids on the nanoscale. view more (2008-02-04)
Geoengineering could slow down the global water cycle
As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures. view more (2008-05-28)
MIT finds young planets stay hotter longer
Hot, young planets may be easier to spot because they stay that way longer than astronomers have thought, according to new work by MIT planetary scientist Linda Elkins-Tanton. view more (2008-10-16)
Archaeologists to establish true value of Roman silver coins
An archaeologist at the University of Liverpool is examining more than 1,000 Roman silver coins from museums around the world in order to establish their true economic value. view more (2006-03-03)
Climate models need deeper roots, scientists say
By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics. view more (2005-12-06)
Biodegradable napkin — featuring sensitive nanofibers — may quickly detect biohazards
Detecting bacteria, viruses and other dangerous substances in hospitals, airplanes and other commonly contaminated places could soon be as easy as wiping a napkin or paper towel across a surface, says a researcher from Cornell University. view more (2006-09-12)
No more hammering please!
Whether it's inspecting glider wings or modern windmill rotor blades, today's method is archaic. Using tap testing, the experienced ear listens for hollow spaces and other defects. A much faster process measures heat distribution resolved over distance and time. Rotor blades for wind turbines are manufactured in the same way as in the good old... view more... (2004-05-14)
Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)
Detox cure for art treasure
Many museums and churches own pieces of art which were treated with toxic pesticides in the past. Between the 1940’s and 80’s, it was quite usual to protect wood against insects and microorganisms with PCP (pentachlorophenol), DDT and lindane. Though the adverse effect was only recognized later: Lindane and PCP evaporate into the air,... view more... (2002-09-09)
Recent developments in the mathematical theory of water waves (Royal Society Philosophical Transactions A)
The last decade has seen vigorous activity in mathematical theory for the motion of water waves by several independent international research groups, and in 2001 a workshop on mathematical problems of nonlinear hydrodynamic waves was held at the conference centre at Oberwolfach, Southern Germany. The aim of this workshop was to bring these groups... view more... (2002-09-10)
Scripps research scientists find cause of cartilage degeneration in osteoarthritis
The scientists describe their work in this week's Early Edition of the Proceedings of the National Academy of Sciences. In the study, the team shows how the loss of the protein HMGB2, found in the surface layer of joint cartilage, leads to the progressive deterioration of the cartilage that is the hallmark of osteoarthritis. view more (2009-01-13)
Chemical industry helped by small invisible tube
Chemists at Utrecht University have developed a catalyst for fine chemistry. Tiny tubes of graphite are the carrier for this catalyst. PhD student Tijmen Ros successfully tested the catalyst with a standard reaction. Fellow researchers are now making the catalyst suitable for the production of cinnamon alcohol, an aromatic substance and... view more... (2002-01-24)
Making more efficient fuel cells
Bacteria that generate significant amounts of electricity could be used in microbial fuel cells to provide power in remote environments or to convert waste to electricity. view more (2009-09-08)
