Probing atomic chicken wire

Graphene -- a sheet of carbon atoms linked in a hexagonal, chicken wire structure -- holds great promise for microelectronics. Only one atom thick and highly conductive, graphene may one day replace conventional silicon microchips, making device...

MIT– parts of brain can switch functions

Cambridge, MASS- When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex...

Fingerprints of a gold cluster revealed

Nanometre-scale gold particles are currently intensively investigated for possible applications in catalysis, sensing, photonics, biolabelling, drug carriers and molecular electronics. The particles are prepared in a solution from gold salt...

Iowa State, Ames Lab researchers describe the pump that bacteria use...

AMES, Iowa -- A research team led by Edward Yu of Iowa State University and the Ames Laboratory has identified and described two parts of the three-part system that pumps toxins from bacteria and allows them to resist antibiotics. The discove...

3-D nanoparticle in atomic resolution

In chemical terms, nanoparticles have different properties from their «big brothers and sisters»: they have a large surface area in relation to their tiny mass and at the same time a small number of atoms. This can produce quantum effects that lea...

Earth’s core rotating faster than rest of the planet but slower...

New research gives the first accurate estimate of how much faster the Earth's core is rotating compared to the rest of the planet. Previous research had shown that the Earth's core rotates faster than the rest of the planet. However, scienti...

UMass Amherst biologists use GPS to ‘map’ bats teeth to explore...

Using a method based on geographic positioning systems that allowed them to characterize the topography of the bats' molars in a way similar to how geographers characterize mountain surfaces, the researchers calculated a measure of dental complexity...

Macho muscle cells force their way to fusion

In fact, according to new research from Johns Hopkins, the fusion of muscle cells is a power struggle that involves a smaller mobile antagonist that points at, pokes and finally pushes into its larger, stationary partner using a newly identified ...

Astronomers identify thick disc of older stars in nearby Andromeda galaxy

An international team of astronomers has identified for the first time a thick stellar disc in the Andromeda galaxy, the nearest large spiral galaxy to our own Milky Way. The discovery of the thick disc, a major result from a five-year investiga...

Math may help calculate way to find new drugs for HIV...

Using mathematical concepts, Princeton researchers have developed a method of discovering new drugs for a range of diseases by calculating which physical properties of biological molecules may predict their effectiveness as medicines. The techn...
