New insight into how brain 'learns' cocaine addiction
A team of researchers says it has solved the longstanding puzzle of why a key protein linked to learning is also needed to become addicted to cocaine. Results of the study, published in the Aug. 1 issue of the journal Cell, describe how the learning-related protein works with other proteins to forge new pathways in the brain in response to a drug-induced rush of the "pleasure" molecule dopamine.

Key step in molecular 'dance' that duplicates DNA deciphered
Scientists have captured new details of the biochemical interactions necessary for cell division -- molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target. The research may suggest ways for stopping cell division when it goes awry.

Scientists identify promising antiviral compounds
Scientists at the US Department of Energy's Brookhaven National Laboratory have identified two promising candidates for the development of drugs against human adenovirus, a cause of ailments ranging from colds to gastrointestinal disorders to pink eye. The researchers sifted through thousands of compounds to determine which might block the effects of a key viral enzyme they had previously studied in atomic-level detail.

This image could lead to better antibiotics
Berkeley Lab scientists have created an atomic-scale structure of a bacterial ribosome attached to a molecule that controls its motion. The image is also a possible roadmap to better antibiotics. Somewhere in its twists and turns could be a weakness that a new antibiotic can target.

Chemists work to desalt the ocean for drinking water, 1 nanoliter at a time
By creating a small electrical field that removes salts from seawater, chemists have introduced a new method for the desalination of seawater that consumes less energy and is dramatically simpler than conventional techniques. The new method requires so little energy that it can run on a store-bought battery.

Salmonella infection is a battle between good and bad bacteria in the gut
A new study in PLOS ONE that examined food poisoning infection as-it-happens in mice revealed harmful bacteria, such as a common type of Salmonella, takes over beneficial bacteria within the gut amid previously unseen changes to the gut environment. The results provide new insights into the course of infection and could lead to better prevention or new treatments.

Making sense of patterns in the Twitterverse
If you think keeping up with what's happening via Twitter, Facebook and other social media is like drinking from a fire hose, multiply that by seven billion -- and you'll have a sense of what Court Corley wakes up to every morning. Corley has created a powerful digital system, dubbed SALSA, capable of analyzing billions of tweets and other messages in just seconds, in an effort to discover patterns and make sense of all the information.

More fresh air in classrooms means fewer absences
If you suspect that opening windows to let in fresh air might be good for you, a new study by scientists at Lawrence Berkeley National Laboratory has confirmed your hunch. Analyzing extensive data on ventilation rates collected from more than 150 classrooms in California over two years, the researchers found that bringing classroom ventilation rates up to the state-mandated standard may reduce student absences due to illness by approximately 3.4 percent.

Salmonella uses protective switch during infection
For the first time, researchers have found a particular kind of molecular switch in the food poisoning bacteria Salmonella Typhimurium under infection-like conditions. This switch, using a process called S-thiolation, appears to be used by the bacteria to respond to changes in the environment during infection and might protect it from harm, researchers report this week online in the Proceedings of the National Academy of Sciences Early Edition.

Tiny wireless device shines light on mouse brain, generating reward
Using a miniature electronic device implanted in the brain, scientists at Washington University School of Medicine in St. Louis and the University of Illinois in Urbana-Champaign have tapped into the internal reward system of mice, prodding neurons to release dopamine, a chemical associated with pleasure. The scientists report their findings in the journal Science.

A bright idea: Tiny injectable LEDs help neuroscientists study the brain
A new class of tiny, injectable LEDs is illuminating the deep mysteries of the brain. Researchers at the University of Illinois at Urbana-Champaign and Washington University in St. Louis developed ultrathin, flexible optoelectronic devices -- including LEDs the size of individual neurons -- that are lighting the way for neuroscientists in the field of optogenetics, a new area of neuroscience that uses light to stimulate targeted neural pathways in the brain.
