Brightening prospects of using fluorescent nanotubes in medical applications

...systems – begin fading within a few hours. Quantum dots last several days before degrading. Hertel’s team is currently working on the next step necessary for many biomedical uses: finding a way to attach molecules to the surface of the nanotubes that will allow them to bind to specific biological targe...

Leeches ferry infection among newts

...ions in the newts appear as clusters of small dark dots under the skin, which can later develop into a large area of swollen muscle. The swollen muscle contains many spores (also called spherules), each of which contains hundreds of infectious cells called endospores. Raffel and his colleagues think that ...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

... technology involves embedding fluorescent quantum dots and magnetic iron oxide nanoparticles inside the b...ptical beads. Nie and Sathe synthesize the quantum dots in different colors by varying their size, giving the beads a unique optical signature. Having diffe...

Ring-around-the-cell

.... When the osteoclast is on the move, these little dots amble randomly around the cell, but when the cells prepare to dissolve the bone, they make a beeline for the edge. Scientists had been unsure how podosomes were involved in ring formation or, if they did form the ring, whether they somehow fused toge...

Embryonic patterning makes the feathers fly

...t watching the formative process of stripes versus dots play out was fascinating. From those feathery patterns, a team of theoretical biologists was able to develop a mathematical model that simulated the process of periodic pattern formation. This kind of basic work can throw light on health problems lik...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...smallpox requires much more than simply connecting dots on a map. Instead Longini and colleagues rely on a tool called stochastic modeling to take into account real-world unpredictability, as well as many factors about the disease and the affected population. In constructing these models, Longini and coll...

UF scientists restore sight to chickens with blinding disease

.... So I did this simple little test, drawing little dots on a piece of paper. The chick, which was standing on the table, came over to the paper and started pecking at all of them. It was so exciting." Later, more precise tests showed that of the seven treated chickens, five displayed near-normal visual b...

UC Riverside psychologist explores human perception, finds 'wow factor'

...t just from lips, but from the simple movements of dots placed on lips, teeth and tongue. They can also recognize people's voices just from seeing their faces, and vice versa, and seem to be able to distinguish among a variety of rooms on campus just from their echoes. "We get people ready for a test an...

Animal brains 'hard-wired' to recognize predator's foot movements, Queen's study suggests

Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria

...ectin microarrays--small glass plates covered with dots of sugar-binding proteins called lectins. The lectin dots act like microbe Velcro. Bacteria with a surface sugar that matches a specific lectin stick to that ...

Researchers solve mystery of how nuclear pores duplicate before cell division

...lit to give rise to two daughter pores, two bright dots would have emerged from one; however, the researchers tracked movement of only one dot, confirming their previous finding that pores formed from scratch. Additional research demonstrated that nuclear pore assemblies are added in a stepwise, coordina...

Cellular scale drug delivery from the inside out

... semiconductor nanocrystals ?also known as quantum dots ?and are held in place by chemical bonds. Once the nanospheres are inside the target cells, a trigger is used to pop the caps off and release the drug. "We're looking at two levels of control," Lin said of the trigger mechanism. "One level is to hav...

New nanosensor uses quantum dots to detect DNA

...We are the first to demonstrate the use of quantum dots as a DNA sensor," Wang said. Quantum dots are crystals of semiconductor material, whose sizes are only in the range of a few nanometers across...

New antifreeze protein found in fleas may allow longer storage of transplant organs

... was serendipity," she says now. "They looked like dots of pepper sprinkled on the snow. Later we were able to collect large numbers for testing at the Queen's University Biological Station." Using a process called ice affinity purification, the team isolated the new protein, which is rich in an amino a...
