...er. That led to reduced concerns about widespread dispersion of CNTs in the water environment. The new study, however, showed that CNTs interact with natural organic matter, which is present in lakes and rivers, in ways that lead to wider dispersion. The researchers conclude: "These findings suggest that dis...Binghamton University researcher makes major biofilm dispersion breakthrough

The dispersion autoinducer Davies is now investigating has shown itself to be effective in dispersing biofilms cont...On the track of tiny larvae, a new model elucidates connections in marine ecology
...etic forecasting to help scientists predict animal dispersion patterns and details of the ecology of coral reefs across the Caribbean Sea. The work is reported by Heather M. Galindo and Stephen R. Palumbi of Stanford University, and Donald B. Olson of the University of Miami, and appears in the August 22nd issu...Ultrasound affects embryonic mouse brain development
...in the adjacent white matter. "The magnitude of dispersion of labeled neurons was highly variable but increased with duration of exposure to ultrasound waves," Rakic said. "These findings suggested the desirability of further work in this area. We do not have any evidence ourselves that USW cause behavioral...Creative economy grows despite large population growth of creative people
...al Growth and Change, offers a look into trends of dispersion in the creative economy. "Across regions of the U.S., some types of industries and sectors become more and more concentrated over time when areas that start with an initial stronghold grow faster than those starting from scratch," Gabe says. ...News tips from the Journal of Neuroscience
...ch et al. examined the causes of this granule cell dispersion (GCD) in mice after intrahippocampal injections of kainic acid (KA). This protocol induced repeated hippocampal seizures (nonconvulsive status epilepticus) of up to 24 hours. The seizures were followed by degeneration of ipsilateral CA3, hilar, and C...Experts: Expanding biotechnology research in developing countries key to countering bioterrorism

This global dispersion of science mandates a global approach to ensuring the science is not misused, intentionally or carelessly, to fuel next generation bio-weapons."

...century, concurrent with the use and environmental dispersion of synthetic PCBs. Although their production has been banned for more than 25 years in the United States due to toxicological concerns, PCBs persist in the environment and remain in humans because they break down slowly.

In addition to providing ecological information about one particular fish species, the work suggests ways that the ecology of other fish can be studied a...Salivating aphids and dynamic proteins
...y changing their shape and acting as a 'plug'. The dispersion of the forisome protein prevents fluids from leaking out of the plant (otherwise your plants would 'bleed' to death when you mow your lawn!). Aphids overcome this blockage by injecting their saliva into the plant. The forisome's shape sensitivity t...The clustering of Hox genes is not necessary for their proper function
...ast 60 millions years. They also observed that the dispersion of Hox genes does not affect their expression and consequently their function. Therefore, at least in the fruit fly, the clustering of Hox genes is not necessary for their proper function. The fruit fly Drosophila is not the only exception to the ru...Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

"We have shown that the dispersion of thousands of brightly emissive multi-porphyrin fluorophores within the polymersome membrane can be used to optically image tissue structures deep below the skin with the potential to go even deeper," said Michael J.

...omosome often disperse away from one another. This dispersion indicates that part of the function of the DNA repair machinery after a double-strand break is to help DNA ends resist the pulling forces of the mitotic spindle. This keeps the broken ends together as the DNA is repaired and leads to proper chromosom...
