Palladium catalysts containing unique molecular ligands couple aromatic rings together in surprising ways

Scientists in Japan have developed a palladium-catalyzed procedure that couples aromatic rings in completely unexpected ways, thanks to a new molecular ligand with specially designed spatial attributes.

Paper battery co. hints about its tech

In the halls of the Cleantech Forum today in San Francisco, a startup stealthily described its new paper-based battery.

Early days for cleantech and IT: smart systems, efficiency

Financial incentives aren’t the only means corporations are looking at to get consumers to change behavior for a more sustainable future.

Single-dose HIV DNA vaccine induces long-lasting immune response in monkeys

For the first time researchers from the U.S. and abroad have shown a single-dose HIV DNA vaccine can induce a long-lasting HIV-specific immune response in nonhuman primates, a discovery that could prove significant in the development of HIV vaccines.

Ancient DNA reveals caribou history linked to volcanic eruption

DNA recovered from ancient caribou bones reveals a possible link between several small unique caribou herds and a massive volcanic eruption that blanketed much of the Alaskan Yukon territory in a thick layer of ash 1,000 years ago, researchers report.

The Toxicity of Antimicrobial Silver in Products Can Be Reduced

A team of chemists from the University of Helsinki has developed a method of manufacturing silver nanoparticles which are polymer-stabilized. The researchers believe that by binding the nanoparticles to polymers they can reduce human exposure to the silver nanoparticles, which have potentially hazardous health effects.
