To control germs, scientists deploy tiny agents provocateurs
Aiming to thwart persistent bacterial infections and better control group behaviors of certain microorganisms, scientists are creating artificial chemicals that infiltrate and sabotage bacterial

Scientists create, study methane hydrates in 'ocean floor' lab
Scientists at Brookhaven National Laboratory have recreated the high-pressure, low-temperature conditions of the seafloor in a tabletop apparatus for the study of methane-hydrates, an abundant but currently out-of-reach source of natural gas trapped within sediments below the ocean floor.

Molecular wires & corrosion control boost performance of conductive adhesives
Using self-assembled monolayers -- essentially molecular wires -- and a three-part anti-corrosion strategy, researchers have boosted the performance of electrically conductive adhesives to the point that they can compete with the tin-lead alloy solders they are designed to replace.

New fingerprint visualization method uses X-rays to reveal missing clues
Dusting for fingerprints can sometimes alter the prints, erasing valuable forensic clues.

Disease diagnosis, biodefense among UH chemical research projects
With 33 presentations of original research that showcase applications ranging from early-stage disease diagnosis to fuel cells and batteries, the University of Houston will be well represented at the 229th National Meeting of the American Chemical Society, March 13 to 17 in San Diego.

Brain imaging suggests how higher education helps to buffer older adults from cognitive decline
College seems to pay off well into retirement. A new study from the University of Toronto sheds light on why higher education seems to buffer people from cognitive declines as they age.

In solution, tiny magnetic wires scatter light
Maneuvering external magnets, scientists can command the direction in which light bounces off tiny, magnetic wires that sway like matchsticks in thick, slow-moving solutions.

Chemicals in tattoo inks need closer scrutiny
As tattoos have grown in popularity, so have complaints of adverse side effects associated with both their application and removal.

Medical molecules designed to respond to visible light that can penetrate tissue
Scientists believe that they can use light at the wavelength that is not absorbed or reflected away by tissue in order to signal manmade molecules to release drugs at disease sites in the body.

Launch of Beilstein Journal of Organic Chemistry announced
The prestigious Beilstein-Institut today announced the launch of the first major Open Access journal for organic chemistry at the American Chemical Society 229th Annual Meeting in San Diego, California.

Silence the gene, save the cell: RNA interference as promising therapy for ALS
Scientists at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have used RNA interference in transgenic mice to silence a mutated gene that causes inherited cases of amytrophic lateral sclerosis (ALS), substantially delaying both the onset and the progression rate of the fatal motor neuron disease. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
