Tracing African-American Ancestry Difficult

Mitochondrial DNA may not hold the key to unlocking the ancestry of African Americans, according to a study by a University of South Carolina researcher published in this week’s issue of the journal BMC Biology.

Molecular Spintronic Action Confirmed in Nanostructure

Researchers at the National Institute of Standards and Technology have made the first confirmed “spintronic” device incorporating organic molecules, a potentially superior approach for innovative electronics that rely ...

Researchers make nanosheets that mimic protein formation

How to direct and control the self-assembly of nanoparticles is a fundamental question in nanotechnology. University of Michigan researchers have discovered a way to make nanocrystals in a fluid assemble into free-floating ...

Day and night temps measured on an extrasolar planet

For the first time, astronomers have measured the day and night temperatures of a planet outside our solar system. The team revealed that a giant Jupiter-like gas planet orbiting very close to its star is blisteringly hot ...

New Quantum Technology Controls Molecules

A research team at the National Research Council Canada (Ottawa) has developed a new quantum technology which uses laser pulses to control quantum processes. The method, which is described in the October 13th web release ...

First detailed pictures of asteroid reveal bizarre system

The first detailed images of a binary asteroid system reveal a bizarre world where the highest points on the surface are actually the lowest, and the two asteroids dance in each other's gravitational pull.

NIST releases new standard for semiconductor industry

A wide range of optical electronic devices, from laser disk players to traffic lights, may be improved in the future thanks to a small piece of semiconductor, about the size of a button, coated with aluminum, gallium, and ...

Fossilized liquid assembly: Nanomaterials research tool

From a butterfly's iridescent wing to a gecko's sticky foot, nature derives extraordinary properties from ordinary materials like wax and keratin. Its secret is hierarchical topology: macroscale structures assembled from ...

A Ruler of Gold and DNA

Scientists from the U.S. Department Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley have developed a ruler made of gold nanoparticles and DNA that can measure the smallest of ...
