A team of scientists led by Jennifer Doudna solved the 3D structure of a large portion of an RNA enzyme, revealing its ability to trigger cell activity and potentially provide the first method for genetic reproduction. This breakthrough could help design new drugs to fight lethal viruses and repair genetic errors.
Researchers at Purdue University have developed an ultrathin film made from gold atoms that conducts electricity by allowing electrons to 'hop' one at a time. This new material, called linked cluster network, could lead to the development of more powerful computers and miniaturized electrical devices.
Scientists at ORNL have synthesized a range of metal and semiconductor nanocrystals embedded in materials like silica and sapphire. These nanocrystals could enable faster, smarter computers and improved flat-panel displays.
Researchers from the University of Washington have developed a reproducible method demonstrating that subliminal messages can influence human cognition. The technique, called the response window technique, uses a brief flicker of time to test unconscious cognition on over 300 volunteer subjects.
The American Association for the Advancement of Science reports that Alaska's R&D funding may be reduced by 19-23% due to federal budget cuts, impacting research at universities and colleges. The University of Alaska Fairbanks receives 90% of the state's federal funding for academic R&D.
A US chemist, Cliff Meloan, has developed a comprehensive training manual to help Central American food inspectors detect pesticide residues using advanced analytical methods. The manual, published in 1996, covers procedures for handling raw and processed foods, identifying chemical compounds, and quality control and assurance.
A team of US researchers has cracked the three-dimensional atomic structure of a large RNA molecule, achieved after four years of research. The new image shows the densely packed and highly organized double-helix-shaped regions of the molecule, with magnesium ions providing 'glue' for its organization.
Research at Brandeis University reveals the human brain's ability to quickly adapt to changing gravitational forces. Directed motions such as pointing and walking speed are significantly affected by changes in gravity.
