Researchers tracking sources of arsenic contamination in water
... impacts the transport of arsenic. Arsenic is more mobile
under anaerobic conditions, while under aerobic conditions, it is bound to iron minerals," she said "So we are asking, "What happens to arsenic as it is transported from groundwater to surface water? Is it retained at the interface between the two zo...

prey like flying fishes associated with sub surface predators such as tunas. To spot prey patches at distance birds climb regularly to altitudes of 20-50m and when returning to the colony they climb to altitudes up to 500m to avoid attacks by frigate...
INEEL-designed system assists army with chemical weapon destruction
.... INEEL engineers have designed and built several mobile
systems for the U.S. Army to assess recovered chemical weapons materiel found in the field, such as the bomblets recently discovered at Rocky Mountain Arsenal in Colorado, or the World War I weapons found in suburban Washington, D.C. The Pine Bluff A...

Brain controls robot arm in monkey, University of Pittsburgh researcher reports at AAAS
...thesis moves much like a natural arm, with a fully mobile
shoulder and elbow and a simple gripper that allows the monkey to grasp and hold food while its own arms are restrained. Computer software interprets signals picked up by tiny probes inserted into neuronal pathways in the motor cortex, a brain region...
New cyber security protocol for online banking, and more
...This is useful to safeguard communications between mobile
units, such as between members of emergency crews who are connected through wireless networks built "on the fly." These so-called "ad hoc" networks hold great potential for military and emergency response applications where network infrastructures ha...
Insight into DNA's 'weakest links' may yield clues to cancer biology
...nsposons" called Ty elements. Retrotransposons are mobile
gene segments that duplicate themselves and insert the new copies back into other sites in the genome. The most common breakpoint involved two Ty elements in an inverted, head-to-head orientation, they reported. That finding led the researchers to s...

Research breakthrough in the understanding of the spread of cholera
... suggesting that adult non biting midges, a highly mobile
flying insect group (Chironomidae), are the vectors that may support continental and intercontinental distribution of cholera. Until 1967, researchers believed that humans may be the reservoir of cholera disease in the inter-epidemic period. In 2001...

Researcher gets NSF grant to create mutant maize lines
...other. Called transposons, or jumping genes, these mobile
pieces of DNA knock out the function of genes they jump into, thereby mutating the genetic makeup. What is unique about this collection is that a single gene will be disrupted in each line while the 50,000 or so other genes are kept exactly the same ...
