Experiment Shows Magnetite As Source of Bat Navigation |
|
Friday, 29 February 2008 |
|
Pulsing bats with a magnetic field 5000 times stronger than that of the Earth's, researchers have shown that biogenic magnetite crystals are used as the main source of compass orientation information in the big brown bat. The study, conducted by scientists from Leeds and Princeton, further indicates that magnetoreceptor cells that provide compass information to the animals are sensitive to magnetic polarity.

Svalbard Global Seed Vault Opens |
|
Wednesday, 27 February 2008 |
|
One hundred and thirty meters deep inside a mountain on a remote
Norwegian island the Svalbard Global Seed Vault has the potential
to store up to 4.5 million seed samples. Managed my NordGen, the seed
vault is viewed as a way to prevent the futher loss of biodiversity and
ensure food production capabilities in case of natural or man-made
disaster. The site was chosen for its tectonic stability, permafrost
conditions, remote location and access to local power production. Read

NSF Partners With Google and IBM |
|
Wednesday, 27 February 2008 |
|
Dedicating approximately 1600 processors to the Cluster Exploratory, or
CluE, Project, Google and IBM hope to enhance the research
capabilities of academic institutions worldwide. Running the open
source platform Apache Hadoop, the program is geared towards
research on Internet-scale computing and application development. The
National Science Foundation (NSF) will oversee the proposals and
grants. The NSF plans to support 10-15 projects in the next year. For

Nanotechnology Holds Promise of Clean Water |
|
Wednesday, 27 February 2008 |
|
Using the electrostatic properties of functionalized self-assembled
monolayer hydrocarbons with a silicon-containing anchor, scientists at
the University of South Australia may have found a key to reducing the
cost of water purification. The coated silica is added to water as a
powder, stirred and filtered back out. It has been shown to remove
Polio virus, Escherichia coli and Cryptosporidium parvum, along with
other biological molecules. For more on this discovery, click here . For the abstract from Inderscience Publishers, click here.
