First direct electric link between neurons and light-sensitive nanoparticle films created
02-27-2007 · EurekAlert!The world's first direct electrical link between nerve cells and photovoltaic nanoparticle films has been achieved by researchers at the University of Texas Medical Branch at Galveston (UTMB) and the University of Michigan. The development opens the door to applying the unique properties of nanoparticles to a wide variety of light-stimulated nerve-signaling devices -- including the possible development of a nanoparticle-based artificial retina.

- Experience affects new neuron survival in adult brain; study sheds light on learning, memory
03-22-2007 · EurekAlert!
Experience in the early development of new neurons in specific brain regions affects their survival and activity in the adult brain, new research shows. How these new neurons store information about these experiences may explain how they can affect learning and memory in adults.

- New nanoparticle could provide simple early diagnosis of many diseases
08-20-2007 · EurekAlert!
Georgia Tech and Emory University researchers have created a new nanoparticle that could someday act as a virtually all-purpose diagnostic tool to detect many inflammatory diseases in their earliest stages, including heart disease, Alzheimer's, heart disease and arthritis. The specially-designed nanoparticles seek out hydrogen peroxide (thought to be overproduced in trace amounts in the early stages of most diseases that involve some sort of chronic inflammation in the body), and emit light when they encounter it.

- First-ever study to link increased mortality specifically to carbon dioxide emissions
01-03-2008 · EurekAlert!
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere incorporating scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency's recent ruling against states setting specific emission standards for this greenhouse gas.

- Polymer opal films shed new kind of light on nature
07-23-2007 · EurekAlert!
Imagine cleaning out your refrigerator and being able to tell at a glance whether perishable food items have spoiled, because the packaging has changed color, or being able to tell if your dollar bill is counterfeit by stretching it to see if it changes hue. These are two commercial applications for a new type of flexible plastic film, developed by scientists at the University of Southampton in the United Kingdom and Darmstadt in Germany.

- Smart thin film membranes adopt properties of guest molecules
03-28-2007 · EurekAlert!
Virginia Tech researchers announced last year that they had created a nanostructured membrane that incorporates DNA base pairs in order to impart molecular recognition and binding ability to the synthetic material. This year they will show for the first time that these new films, membranes, and elastomers are compatible with diverse organic and inorganic molecules and will adopt properties of the guest molecules.

- U-M scientists find new causes for neurodegeneration
10-24-2007 · EurekAlert!
Diseases that cause neurons to break down, such as Alzheimer's, continue to be elusive to scientists and resistant to treatments. A new finding from University of Michigan researchers demonstrates an unpredicted link between a virtually unknown signaling molecule and neuron health. In a study released in PNAS this week, Lois Weisman connects the loss of this molecule to massive neurodegeneration in the brain, which plays a key role in the survival of nervous system cells.

- A drug-sensitive 'traffic cop' tells potassium channels to get lost
09-02-2007 · EurekAlert!
Our brains are buzzing with electrical activity created by sodium and potassium ions moving in and out of neurons through specialized pores. To prevent the constant chatter from descending into chaos the activity of these ion channels has to be tightly regulated.

- Light-sensitive photoswitches could restore sight to those with macular degeneration
10-31-2006 · EurekAlert!
The major cause of blindness in this country is the death of photoreceptors -- rods and cones -- in the retina, a disease called macular degeneration. A possible new therapy involves inserting photoswitches into surviving retinal cells, giving them the gift of sight. NIH's nanomedicine initiative just awarded UC Berkeley and Lawrence Berkekley National Laboratory scientists $6 million to pursue this technique in mice.
