Ants show us how to make super-highways

...ad repairs, the ants have their own do-it-yourself highways agency." "When the traffic has passed, the down-trodden ants climb out of the potholes and follow their nest mates home," added Powell. "Broadly, our research demonstrates that a simple but highly specialised behaviour performed by a minority of ...

Scientists map air pollution using corn grown in US fields

...scientists avoided pollution point sources such as highways and power plants to allow for mapping of regional patterns across different states. Back in the laboratory, the scientists dried samples of corn leaves and husks, then converted them to graphite using a series of chemical reactions. The graphite then...

UCSD researchers create roadmap to integrin activation

...gs. "If you think of these pathways as interstate highways on a map, this study now enables us to see other back roads that lead to the destination," said Ginsberg. Talin is also critical for activation of related integrins, such as those on white blood cells. In these cells, activation of integrins is a c...

Creating a window on 'oceans in motion'

...rivers. Knowing their usual travels along marine highways has far-reaching implications for authorities that need to determine when fisheries should be open or closed to conserve endangered stocks. Other scientists from around the world attending the conference have placed related technology on a variety o...

The Amazon in 2050: Implementing the law could save a million square kilometers of rainforest

...how individual policies ranging from the paving of highways to the requirement for forest reserves on private ...errun many species with small ranges. Of the major highways planned for paving, the Manaus-Porto Velho highway will be the most damaging in terms of new defores...

Software 'agents' could help unmask reality of disease clusters

...the risk of exposure to lead associated with urban highways or clusters of cancer cases. "Such widespread concerns can only be addressed using micro data and access to this often involves lengthy and cumbersome procedures through review boards and committees for approval, and sometimes it is just not possibl...

Emerald Spectre haunts Ontario's ash forests

... borer are under quarantine. Prominent signs along highways advise the public of the total ban on the transport out of the area of ash trees, saplings and firewood. During the winter of 2003-2004, the CFIA took the dramatic step of creating a borer "firewall" in Ontario's Essex County. That involved removing ...

Brain networks change according to cognitive task

...esulam compares the brain networks to a network of highways connecting different parts of a city. The highway is static. No matter how heavy the traffic load, it always has the same number of lanes. In the brain, there is a dynamic change that allows certain pathways to preferentially facilitate the demands o...

Motor transport in bio-nano systems

...ic jams. These jams are similar to the jams on our highways but there are also important differences. First, the molecular motors cannot 'see' other motors and their cargo before they bump into them. Second, in contrast to our cars, which cannot leave the highway when they are caught in a jam, the molecular m...

Amazon symposium to address large-scale conservation

...rkets for open-range beef and grain. The paving of highways into the heart of the region will facilitate the export of Amazon products to world markets as it creates new corridors for explosive frontier expansion. These mounting threats to the Amazon require large-scale, integrated approaches to conservation ...
