Estrogen protects liver after traumatic injury
Researchers have identified the receptor pathway used by estrogen to decrease liver injury after trauma and hemorrhage. view more (2007-04-02)
Shark skin saves naval industry money
Covering ship hulls with artificial shark skin could help ships sailing smoothly. The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'. view more (2005-07-18)
Production of spherical beads with the JetCutter
A major problem in particle production technology is the large scale production of uniform beads from viscous fluids. Producing such beads is of interest in various industrial sectors, e.g. chemical, pharmaceutical and food industry, agriculture, biotechnology. The JetCutter is a new and simple technology for bead production that meets the... view more... (2003-11-03)
Soggy Sands of Mars?
Cracks and fins in the sand in an American desert look very similar to features seen on Mars and may indicate the recent presence of water at the surface. view more (2006-04-07)
Antarctic krill provide carbon sink in Southern Ocean
New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth's surface than was previously understood. view more (2006-02-07)
Chandrayaan-1 now in lunar orbit
Chandrayaan-1, the Indian Space Research Organisation's (ISRO) lunar orbiter, was captured into orbit around the Moon on 8 November. One day later, the spacecraft performed a manoeuvre that lowered the closest point of its orbit down to 200 km from the Moon. view more (2008-11-11)
Has SOHO ended a 30-year quest for solar ripples?
The ESA-NASA Solar and Heliospheric Observatory (SOHO) may have glimpsed long-sought oscillations on the Sun's surface. The data will reveal details about the very core of our central star and it contains clues as to how the Sun formed, 4.6 billion years ago. view more (2007-05-04)
Smaller microchips that consume less energy
To develop ever-smaller chips that consume less. These are the indispensable requirements of the current market for portable applications such as mobile telephone technology and biomedical systems, obtaining correct and trouble-free operation of the devices over the maximum possible duration of time. One of the techniques which, in fact, can be... view more... (2004-09-10)
Self-reported Stress Linked To Fatal Stroke
The dilemma over whether stress causes a stroke became clearer today (27 October) when Dr Thomas Truelsen from the Institute of Preventive Medicine in Copenhagen presented results of a survey on self-reported stress and risk of stroke in which more than12,500 people in Denmark participated. At the European Federation of Neurological Societies... view more... (2002-10-24)
Chemical Bonding States at Silicon / Silicon Dioxide Interfaces Characterisable with Light
The importance of characterising the atomic structure of the silicon / silicon dioxide interface as an essential component in highly integrated circuits has steadily increased as a result of continuing miniaturisation of silicon chips. The physicists, Dr. Stefan Bergfeld, Bjoern Braunschweig and Prof. Dr. Winfried Daum, Institute of Physics and... view more... (2004-08-26)
Protein transport in mitochondria revealed
The TIM23 complex, which regulates the transport of protein to the mitochondria in a cell, is much more complicated than was previously believed. This is shown by Uppsala University researcher Maria Lind in an article in the leading journal Cell. view more (2005-03-31)
High levels of daily stress may result in lower risk of breast cancer
High levels of daily stress appear to result in a lower risk of developing breast cancer for the first time, says a study in this week's BMJ. view more (2005-09-09)
Mushrooms, water-repellants more similar than you might think
What do spore-launching mushrooms have in common with highly water-repellant surfaces? view more (2009-10-27)
FURTHER STEPS TOWARDS A VACCINE AGAINST HIV
For white blood cells in the human body to be infected by the HIV virus, proteins in the virus must be allowed to interact with a number of different components on the surface of the white blood cell. Ideally anti-HIV preventive therapy or vaccines would prevent several of these interactions taking place and would, therefore, reduce the likelihood... view more... (1999-03-11)
Laser treatment restores art
FIRING laser beams at priceless paintings might seem the height of folly, putting the painting`s delicate pigments at risk. So while conservators have for decades used ultraviolet lasers to clean up grubby sculptures, they have always fought shy of using them on soiled paintings. But now a study has shown you can fire away with impunity. Lasers... view more... (2002-09-25)
Biocompatibility to Ensure Body Friendly Parts
In recent years, the solution to the problem of diseased or damaged organs has been to replace the old with the new. By taking tissue from either a patient or a donor, surgeons have transplanted this to the damaged area and given many people a new lease of life. The method is not without limitations, however. Issues such as the availability of... view more... (2003-06-06)
Microprinting Technique for Patterning Single Molecules
A new process for creating patterns of individual molecules on a surface combines control of self-assembled monolayers (SAMs) and a soft lithography technique known as microcontact printing. view more (2007-02-05)
Astronomers hunt Martian water from Earth
As Mars makes its closest approach in almost 60,000 years, two Australian astronomers have used the United Kingdom Infrared Telescope (UKIRT) in Hawaii to look for signs that the planet once had liquid water - and so may have hosted life. Dr. Jeremy Bailey of the Anglo-Australian Observatory and the Australian Centre for Astrobiology (ACA) at... view more... (2003-08-26)
LSU professor finds alternate explanation for dune formation on Saturn's largest moon
A new and likely controversial paper has just been published online in Nature Geoscience by LSU Department of Geography and Anthropology Chair Patrick Hesp and United States Geological Survey scientist David Rubin. view more (2009-08-26)
Step forward for nanotechnology: Controlled movement of molecules
Scientists in the United Kingdom are reporting an advance toward overcoming one of the key challenges in nanotechnology: Getting molecules to move quickly in a desired direction without help from outside forces. view more (2009-10-01)
