Destroying amyloid proteins with lasers
Researchers have found that a technique used to visualize amyloid fibers in the laboratory might have the potential to destroy them in the clinic. view more (2009-01-08)
An 'eye catching' vision discovery
Nearly all species have some ability to detect light. At least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers at the Johns Hopkins School of Medicine have discovered in fish yet another type of cell that can sense light and contribute to vision. view more (2009-07-27)
Clemson scientists shed light on molecules in living cells
Clemson University chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it travels through a living cell. view more (2007-08-21)
Nanoscopic changes to pancreatic cells reveal cancer
A team of researchers in Chicago has developed a way to examine cell biopsies and detect never-before-seen signs of early-stage pancreatic cancer, according to a new paper in the Optical Society (OSA) journal Optics Letters. view more (2009-02-13)
Gold Nanoparticles Emit Intense Heat, Study Finds
Nanoparticles of gold can act as tiny, precise and powerful heaters, which potentially could be used in biomedical applications, according to a new study. view more (2006-03-31)
On a Wire or in a Fiber, a Wave is a Wave
In an experiment modeled on the classic "Young's double slit experiment" and published in the journal Nature Nanotechnology, researchers have powerfully reinforced the understanding that surface plasmon polaritons (SPPs) propagate and diffract just like any other wave. view more (2007-07-16)
Daytime light exposure dynamically enhances brain responses
Exposure to light is known to enhance both alertness and performance in humans, but little is understood regarding the neurological basis for these effects, especially those associated with daytime light exposure. view more (2006-08-22)
Modified electron microscope identifies atoms
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. view more (2008-02-22)
By color-coding atoms, new Cornell electron microscope promises big advance in materials analysis
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. view more (2008-02-22)
Researchers develop marker that identifies energy-producing centers in nerve cells
A protein that causes coral to glow is helping researchers at the University of Maryland School of Medicine to light up brain cells that are critical for the proper functioning of the central nervous system. view more (2007-02-02)
Blue light used to harden tooth fillings stunts tumor growth
A blue curing light used to harden dental fillings also may stunt tumor growth, Medical College of Georgia researchers say. view more (2008-06-25)
'Safety valve' protects photosynthesis from too much light
Photosynthetic organisms need to cope with a wide range of light intensities, which can change over timescales of seconds to minutes. view more (2009-11-30)
Physicists trap, map tiny magnetic vortex
In a research first that could lead to a new generation of hard drives capable of storing thousands of movies per square inch, physicists at Rice University have decoded the three-dimensional structure of a tornado-like magnetic vortex no larger than a red blood cell. view more (2006-09-08)
A new light on the anti-tumor mechanisms of Scutellaria barbata
Medicinal plants have been used as traditional remedies for hundreds of years. Among them, S. barbata has been traditionally used in treatment of hepatitis, inflammation, osteomyelitis and gynecological diseases in China. view more (2009-01-05)
Blink, and the brain misses it
We would immediately notice if the outside world suddenly went dark every few seconds. But we rarely become aware of our blinks, even though they cause a similar reduction in the amount of light entering the eye. So why are we not aware of the frequent mini-blackouts caused by blinks? view more (2005-07-26)
Mystery behind the strongest creature in the world
The strongest creature in the world, the Hercules Beetle, has a colour-changing trick that scientists have long sought to understand. view more (2008-03-11)
Scientists Image 'Magnetic Semiconductors' On The Nanoscale
In a first-of-its-kind achievement, scientists at the University of Iowa, the University of Illinois at Urbana-Champaign and Princeton University have directly imaged the magnetic interactions between two magnetic atoms less than one nanometer apart (one billionth of a meter) and embedded in a semiconductor chip. view more (2006-07-27)
A unique arrangement for egg cell division
Which genes are passed on from mother to child is decided very early on during the maturation of the egg cell in the ovary. view more (2007-08-10)
Tension in the nanoworld
A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. view more (2009-01-26)
Using invisibility to increase visibility
Research into the development of invisibility devices has spurred two physicists' thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat's eye. view more (2008-12-01)
