Molecular motor structural changes imaged

A U.S.-led international team of researchers has shed new light on how tiny molecular motors that transport materials within cells generate energy.

Computer model looks at cooling the Earth

A U.S. computer model study suggests two unusual methods, including injecting sulfates into the atmosphere, might be used to stabilize the Earth's climate.

Ferns provide model for tiny motors powered by evaporation

Scientists looked to ferns to create a novel energy scavenging device that uses the power of evaporation to move itself -- materials that could provide a method for powering micro and nano devices with just water or heat.

IAU names dwarf planet Eris

The International Astronomical Union announces the names Eris for the dwarf planet provisionally named 2003 UB 313 and Dysnomia for its moon.

New 'superlens' reveals hidden nanostructures

A microscope used to scan nanostructures can be dramatically enhanced by using a 'superlens,' reports an international team of scientists from the Max Planck Institute (MPI) for Biochemistry and The University of Texas at ...

Form Determines Function

A team of researchers at the Universities of Bielefeld and Hamburg (Germany) has now produced cyclopeptides that imitate the HNK-1 carbohydrate from human natural killer cells.

Astronomers discover strange new planet

U.S. astronomers have discovered a planet unlike any other known in the universe. Smithsonian scientists say the new planet was discovered using a network of small automated telescopes known as HATl. The planet -- designated ...
