(Physikalisch-Technische Bundesanstalt (PTB)) The new magnetic resonance tomograph which is delivered to its new location on Sept. 11, will be the only one of the modern 7 tesla generation in the world, in which a metrology institute is also involved. And for the first time in the world, cardiovascular research carried out on such a device is now also to play an important role.

Scientists develop a new technique that allows certain objects to be invisible

Posted in chemistry on the September 12th, 2008

(Universidad de Granada) They have used a simulated layer system with the Transmission Line Matrix Modelling method, which is able to hide, in certain frequencies, the objects placed in an electromagnetic simulator. This research work has been carried out by scientists of the University of Granada in collaboration with researchers of the Massachusetts Institute of Technology, and has been recently published in two papers in the prestigious journal Optics Express.

How corals adapt to day and night

Posted in chemistry on the September 12th, 2008

(American Society for Biochemistry and Molecular Biology) Researchers have uncovered a gene in corals that responds to day/night cycles, which provides some tantalizing clues into how symbiotic corals work together with their plankton partners.

Tuberculosis drug shows promise against latent bacteria

Posted in chemistry on the September 12th, 2008

(American Society for Biochemistry and Molecular Biology) A new study has shown that an investigational drug, R207910, is quite effective at killing latent bacteria. This revelation suggests that R207910 may lead to improved and shortened treatments for this globally prevalent disease.

Enzyme Detectives Uncover New Reactions: Implications For Engineering Biofuels

Posted in chemistry on the September 11th, 2008

Scientists have discovered a fundamental shift in an enzyme’s function that could help expand the toolbox for engineering biofuels and other plant-based oil products.

Hydrogen Bonds: Scientists Find New Mechanism

Posted in chemistry on the September 11th, 2008

Water’s unrivaled omnipresence and the crucial role it plays in life drive scientists to understand every detail of its unusual underlying properties on the microscopic scale. Researchers now report how water solvates its intrinsic hydroxide (OH-) anion. Unraveling this behavior is important to advance the understanding of aqueous chemistry and biology.

World’s First Synthetic Tree: May Lead To Technologies For Heat Transfer, Soil Remediation

Posted in chemistry on the September 11th, 2008

In Abraham Stroock’s lab at Cornell, the world’s first synthetic tree sits in a palm-sized piece of clear, flexible hydrogel — the type found in soft contact lenses. Stroock and graduate student Tobias Wheeler have created a “tree” that simulates the process of transpiration, the cohesive capillary action that allows trees to wick moisture upward to their highest branches.

Arctic science conference to focus on northern sustainability

Posted in chemistry on the September 11th, 2008

(University of Alaska Fairbanks) More than 150 scientists are expected to attend the 59th annual American Association for the Advancement of Science Arctic Division conference in Fairbanks, Alaska, Sept. 15-17, 2008.
