A new metal detector to study human disease
Zinc may be a familiar dietary supplement to millions of health-conscious people, but it remains a mystery metal to scientists who study zinc's role in Alzheimer's disease, stroke and other health problems. view more (2006-03-22)
Connect the Quantum Dots
By using the unique photophysical properties of quantum dots, researchers Drs. Francisco Raymo, Ibrahim Yildiz, and Massimilliano Tomasulo were able to identify operating principles to probe molecular recognition events with luminescence measurements. view more (2006-07-19)
Stengthening the glow of nanotube luminescence
Nanotubes are the poster children of the nanotechnology revolution. These tiny carbon tubes - less than 1/50,000 the diameter of a human hair - possess novel properties that have researchers excitedly exploring dozens of potential applications ranging from transistors to space elevators. view more (2005-11-15)
Early to bed, early to rise
In an upcoming G&D paper, a team of German scientists presents a genetic basis for understanding human morning lark behavior. Dr. Achim Kramer (Charité Universitaetsmedizin Berlin) and colleagues have uncovered a genetic cause for the human familial advanced sleep phase syndrome (FASPS), which causes people to both go to sleep and wake up... view more...

Growing glowing nanowires to light up the nanoworld
The nano world is getting brighter. Nanowires made of semiconductor materials are being used to make prototype lasers and light-emitting diodes with emission apertures roughly 100 nm in diameter-about 50 times narrower than conventional counterparts. view more (2006-05-26)
'Smart' nanoprobes light up disease
Researchers from Rice University's Center for Biological and Environmental Nanotechnology (CBEN) have developed a "smart" beacon hundreds of times smaller than a human cell that is programmed to light up only when activated by specific proteases. view more (2005-08-02)
Archaeologists find earliest evidence of modern humans in Eastern Europe
A University of Arizona archaeologist is a member of a team of scientists that has uncovered new evidence that modern humans moved out of Africa and occupied parts of eastern Europe as early as 45,000 years ago. view more (2007-01-15)
Transition Metal Selenites (Mn, Co, Ni, Fe, Cu, Zn and Cd)
The work involved a multidisciplinary task, undertaking the study of phases of mineralogical and physico-chemical interest. Selenites were synthesised, given that they are a new field and likely to present original physical properties. view more (2005-09-30)
'High Q' NIST nanowires may be practical oscillators
Nanowires grown at the National Institute of Standards and Technology (NIST) have a mechanical "quality factor" at least 10 times higher than reported values for other nanoscale devices such as carbon nanotubes, and comparable to that of commercial quartz crystals. view more (2007-11-28)
Thermometer For Plasma
St. Petersburg researchers have designed an original thermometer for fast-moving electrons in thermonuclear reactors. The laser beam in this device is used to instantly determine the temperature of burning hot plasma, at frequencies required for precise diagnostics. This device is a further step forward to controlled nuclear fusion. The device... view more... (2003-09-05)
Microwave synthesis connects with the (quantum) dots
Materials researchers at the National Institute of Standards and Technology (NIST) have developed a simplified, low-cost process for producing high-quality, water-soluble "quantum dots" for biological research. view more (2008-06-13)
Looking beyond the drug receptor for clues to drug effectiveness
Antipsychotic drugs that are widely used to treat schizophrenia and other problems may not work as scientists have assumed, according to findings from Duke University Medical Center researchers that could lead to changes in how these drugs are developed and prescribed. view more (2008-08-26)
UConn chemists find secret to increasing luminescence efficiency of carbon nanotubes
Chemists at the University of Connecticut have found a way to greatly increase the luminescence efficiency of single-walled carbon nanotubes, a discovery that could have significant applications in medical imaging and other areas. view more (2009-03-06)
Bright lights: Mystery of glowing antibody solved by Scripps research scientists
Now, a group of Scripps Research scientists have shown that EP2-19G2, one of a panel of fluorescent monoclonal antibodies that were first reported in 2000, produces its distinctive bright blue glow through a rare and highly complex recombination of electrical charge. view more (2008-02-29)
Lighting the way to early cancer detection
Scientists at the University of Sussex are pioneering a non-invasive way to identify cancers. The team has vastly improved a system for detecting cancer in the early stages, without putting patients through painful exploratory procedures. The detection works by beaming ultra violet light at a patient and analysing the information reflected. This... view more... (2004-01-06)
New Toxic Sampling Kit Measures Contaminated Land
A University of Surrey spin-out company, Cybersense Biosystems Ltd, has developed a portable toxicity screening device. The ROTAS system can be literally wheeled on to a brown field site and carry out field-based screening of contaminated soils and waters and results can be read within minutes. It is especially relevant with the Government's... view more... (2004-07-22)
Squid 'sight': Not just through eyes
It's hard to miss the huge eye of a squid. But now it appears that certain squids can detect light through an organ other than their eyes as well. view more (2009-06-02)
Nordic Centres of Excellence selected
Four units have been selected to take part in the first Nordic Centres of Excellence programme. They are - A Centre of Excellence concerned with studying ecological systems in climate change. Consisting of research teams based at the Universities of Oslo, Helsinki and Lund, the unit is expected to increase our understanding of the impacts of... view more... (2002-10-31)
Male or female? Coloring provides gender cues
Our brain is wired to identify gender based on facial cues and coloring, according to a new study published in the Journal of Vision. view more (2009-05-28)
Luminescence Dating, a new method of age determination
Physicists and geoscientists join forces in a Dutch research centre. Luminescence dating is a new technology for the determination of the age of sediments such as sand. At the Netherlands Centre for Luminescence Dating (NCL), physicists and geoscientists join forces to use and improve this new method. The foundation of the NCL will be celebrated... view more...
