In an event flanked with all the electric cars that have recently come to market, and a handful of those that are poised for sale later this year, U.S. Energy Secretary Steven Chu and L.A. Mayor Antonio Villaraigosa flipped the switch May 13 on the 500th electric-vehicle charging station installed by Coulomb Technologies as part of its ChargePoint America network.

Researchers in America have shown that ozone -- a known pollutant at low levels in the earth's atmosphere, causing harmful effects on the respiratory system and sensitive plants -- can be reduced, on average, when electric vehicle charging is done at night time.

Researchers are testing different ways of improving rechargeable batteries for electric vehicles and nanotechnology plays an important role in the development. The aim is to offer batteries that have fast charge and discharge rates as well as high stored energy per mass. This can make electric vehicles a competitive alternative to petrol-powered vehicles.

Imagine a cell phone battery that charges with every step you take or a spacesuit that uses astronauts' expended energy to run the suit's electronics. A team of college students conducting NASA research on this innovative use of nanotechnology took their research to new heights. The team, comprising Hannah Clevenson, Olivia Lenz and Tanya Miracle, flew an experiment related to their nanotechnology research on a NASA reduced-gravity flight.

In the growing global battle against substandard and counterfeit medicines, the Promoting the Quality of Medicines (PQM) program has launched a new, public database of medicines collected and analyzed in collaboration with stakeholders from countries in Africa, South America and Southeast Asia. Free of charge and available to anyone with access to the internet, the Medicines Quality Database (MQDB) includes information on the quality of medicines collected from a variety of sources. To date, more than 8700 records of tested samples collected from Ghana, Laos, Vietnam, Cambodia, the Philippines, Thailand, Peru, Guyana and Colombia have been entered into the database.

Flat out wrong. That's what a team of Duke researchers has discovered, much to its surprise, about a long-accepted explanation of how nuclei collide to produce charged particles for electricity - a process receiving intense interest lately from scientists, entrepreneurs and policy makers in the wake of Japan's nuclear crisis.

Policymakers are very familiar with land-use planning. But what is the best approach for planning uses of America's coastal waters and oceans? That question has gained importance since President Obama formed the National Ocean Council last summer and charged it with developing an ecosystem-based stewardship policy for the nation's oceans, coastal waters and the Great Lakes.

The obscure technology used in heated automobile seats, gadgets that charge iPhones from the heat of a campfire, and other devices is undergoing a renaissance and could well emerge as a new "green" substitute for traditional sources of energy and play other key roles in addressing some of society's most pressing sustainability issues. That's the conclusion of an article on the technology - termed thermoelectrics - in the current issue of Chemical & Engineering News (C&EN) the American Chemical Society's weekly newsmagazine.
