Average insect brain should help spot defects and their causes.
A creature of little brain, the fruit fly is popular with geneticists
Two hairs breadths long and five across - thats the average capacity of a flys brain, German researchers have calculated. They hope to set a benchmark for crania by which oddballs can be judged.
Although it is a creature of little brain, the fruit fly (Drosophila) is popular with geneticists. Researchers often study flies that lack a particular gene, looking for flaws that might hint at the genes function in the body.
Efforts to gauge the average human brain are taking a similar tack, says John Mazziotta of the University of California, Los Angeles, who heads the International Consortium for Brain Mapping.
Using magnetic-resonance imaging (MRI) pictures collected from nearly 7,000 people, the team hopes to define a human reference brain. This could be compared to patients with Alzheimers disease or stroke to pinpoint brain regions that are affected. The human standard is set to be completed by September 2003.
"Wed like to have such a reference brain," says Robert Brandt of the Free University of Berlin, who is compiling an equivalent for bees.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
