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...

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)
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)
'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)
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)
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)
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)
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)
Luminescence shines new light on proteins
A chance discovery by a team of scientists using optical probes means that changes in cells in the human body could now be seen in a completely different light. view more (2008-11-12)
Nanocrystals Reveal Activity Within Cells
Researchers at the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory have created bright, stable and bio-friendly nanocrystals that act as individual investigators of activity within a cell. view more (2009-06-17)
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)
Tsunami waves reasonably likely to strike Israel
"There is a likely chance of tsunami waves reaching the shores of Israel," says Dr. Beverly Goodman of the Leon H. Charney School of Marine Sciences at the University of Haifa following an encompassing geo-archaeological study at the port of Caesarea. "Tsunami events in the Mediterranean do occur less frequently than in the Pacific... view more... (2009-10-26)
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)
Nanoscopic probes can track down and attack cancer cells
A researcher has developed probes that can help pinpoint the location of tumors and might one day be able to directly attack cancer cells. view more (2009-03-16)
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...

Novel polymer delivers genetic medicine, allows tracking
Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems. view more (2009-10-07)
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)
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)
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)
'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)
