Bristleworms engineer optics - Photon02
Computer and optical communications engineers are now using optical structures to produce faster, more powerful, light-based processors and networks. However, according to Dr Andrew Parker from Oxford University, they are well behind the times as nature has been making these optical structures for at least 515 million years. He and his team are... view more... (2002-08-28)
The European Research Advisory Board: 3 years of successful work
EURAB, the high level advisory board set up in 2001 on the initiative of European Research Commissioner Philippe Busquin, has completed its first three years of operation. "EURAB has greatly contributed to the higher profile of European research policy on the European Union's agenda", said Philippe Busquin. The 45 members, coming from 19... view more... (2004-06-08)
Nanotech discovery could have radical implications
It has been 20 years since the futurist Eric Drexler daringly predicted a new world where miniaturized robots would build things one molecule at a time. The world of nanotechnology that Drexler envisioned is beginning to come to pass, with scientists conjuring new applications daily. view more (2005-12-01)
Berkeley Researchers Find New Route to Nano Self-Assembly
If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) who have found a simple and yet powerfully robust way to induce... view more...

Human DNA repair process recorded in action
A key phase in the repair process of damaged human DNA has been observed and visually recorded by a team of researchers at the University of California, Davis. The recordings provide new information about the role played by a protein known as Rad51, which is linked to breast cancer, in this complex and critical process. view more (2009-01-29)
The giant protein titin helps build muscles
Under the microscope, muscle looks like millions of tiny pistons, stacked end-to-end into long rows. These structures, called sarcomeres, permit the contraction and relaxation of muscle that allow our bodies to move. view more (2006-01-12)
Researchers provide study of early heart development and underlying cause of congenital heart defects
Congenital heart defects involve the malformation in one or more structures of the heart or blood vessels while the fetus is developing in the uterus. view more (2005-12-21)
Extreme nature helps scientists design nano materials
Scientists are using designs in nature from extreme environments to overcome the challenges of producing materials on the nanometre scale. view more (2008-10-15)
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)
Hybrid renewable energy system
FATRONIK technological centre from the Basque Country has designed and installed a micro-wind generator at the Aubixa Euskal Girotze boarding centre (San Pedro neighbourhood, Elgoibar). Since the end of October the 2.5 kW micro-wind generator has been producing energy which is initially planned to power the boarding centre's four refrigerators,... view more... (2003-11-18)
Polarized particles join toolbox for building unique structures
Researchers at the University of Illinois at Urbana-Champaign have created polarized, spherical particles that spontaneously self-assemble into clusters with specific shapes and distributions of electric charge. view more (2006-10-13)
No more loose screws!
Machine parts and tools with a functional coating made of diamond-like carbon are not only more wear-resistant than usual ones, but also smarter. At the Hanover Fair, visitors can see ”intelligent“ washers and tools that measure whether screws are sufficiently tight. ---------- Modern wind turbines are exposed to a considerable air... view more...

The gold standard: Biodesign Institute researchers use nanoparticles to make 3-D DNA nanotubes
Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offering near limitless construction potential. view more (2009-01-05)
What's the influence of laxative agents on mucosal barrier repair?
The prostone lubiprostone has been shown to stimulate chloride secretion via one of the minor intestinal epithelial channels, ClC-2. This results in sustained low-level secretion of water into the lumen. view more (2008-11-03)
Surface features on Titan form like Earth's, but with a frigid twist
"It is really surprising how closely Titan's surface resembles Earth's," says Rosaly Lopes, a planetary geologist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, who is presenting the results on Friday, 7 August. view more (2009-08-07)
Tackling brake noise
The squeal of brakes is not just irritating and annoying, it damages cars and railway wheel squeal is a serious environmental concern, contributing significantly to inner city noise pollution. EUREKA project E! 2122 BRAKENOISE is tackling the friction-induced vibration that can cause such excessive undesirable noise. The project partners - Bosch,... view more... (2004-01-07)
Lost in translation
The enzyme machine that translates a cell's DNA code into the proteins of life is nothing if not an editorial perfectionist. view more (2009-01-08)
Light-sensitive particles change chemistry at the flick of a switch
A light-sensitive, self-assembled monolayer that provides unique control over particle interactions has been developed by scientists at the University of Illinois at Urbana-Champaign. view more (2006-03-27)
Media Invitation - Cosmology Prize to be awarded at IAU General Assembly, Tuesday 15 July
Two thousand astronomers from 65 countries will converge on the Darling Harbour Convention Centre in Sydney this coming week for the 25th triennial General Assembly of the International Astronomical Union (IAU). The meeting kicks off on Sunday 13 July and runs for two weeks. It will be officially opened at the Sydney Opera House at 6 pm on... view more... (2003-07-12)
Bio-inspired assembly of nanoparticle building blocks
Chemists at Rice University have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature's oldest known chemical innovations - the self-assembly of lipid membranes that surround every living cell. view more (2006-11-28)
