New nanotechnology paints for walls, ceilings, and surfaces could be used to kill hospital superbugs when fluorescent lights are switched on, said scientists today at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

The new paints contain tiny particles of titanium dioxide, which is the dazzling white compound often used as a brightener in commercial paints. It will also be familiar to tennis fans as the powder used for the white lines to mark out the courts at Wimbledon.

Retail medical clinics located in pharmacies and other stores primarily attract both insured and uninsured patients who are seeking help for a small group of easy-to-treat illnesses or preventive care but do not otherwise have a regular health care provider, according to a new RAND Corporation study.

Retail medical clinics are typically located in drug stores and other large retail chain stores, such as Target and Wal-Mart, rather than in medical facilities. There are now almost 1,000 retail clinics in the United States and it is estimated there may be 6,000 by 2011.

The RAND Health study is the first to examine the types of patients who use the retail clinics and the health care services delivered by the clinics, which are growing in number and popularity. The findings are published in the September/October of the journal Health Affairs.

More than 1,500 audiocassette tapes taken in 2001 from Osama bin Laden's former residential compound in Qandahar, Afghanistan, are yielding new insights into the radical Islamic militant leader's intellectual development in the years leading up to the 9/11 terrorist attacks.

Flagg Miller, an assistant professor of religious studies at the University of California, Davis, and the first academic researcher to study the tapes, will present his preliminary observations in a lecture at the Center of Modern Oriental Studies in Berlin on Sept. 18. The first research paper stemming from Miller's study of the tapes will appear in the October issue of the journal Language & Communication.

Women employed in casual and contract jobs are up to ten times more likely to experience unwanted sexual advances than those in permanent full time positions, a University of Melbourne study has found.

The research by Associate Professor Anthony LaMontagne of the McCaughey Centre, VicHealth Centre for the Promotion of Mental Health and Community Wellbeing will be presented at the From Margins to Mainstream Conference: 5th World Conference on the Promotion of Mental Health and the Prevention of Mental and Behavioral Disorders.

Associate Professor LaMontagne's study examined the likelihood of sexual harassment in different types of employment.

Better self-control is linked to higher intelligence. But until now psychologists have been unsure exactly why. Now, researchers at Yale University are the first to report a clue that's helping to understanding why there is a tendency for more intelligent individuals to resist smaller, sooner rewards, while the preference for immediate rewards is associated with lower intelligence (IQ). The study, reported in the Sept. 9th issue of the journal 'Psychological Science,' is the first to investigate--and identify--the neural mechanisms that account for this relationship. The idea is relevant to areas such as personal financial planning and mental health, including massive credit card debt, substance abuse, attention deficit/hyperactivity disorder, and excessive gambling or online gaming. The work suggests that understanding such a relationship could even lead to interventions for enhancing self-control. If a mentally challenging task like a Sudoku improves your IQ, could it help you quit smoking?

Imagine that instead of setting out to invent a better lightbulb, Thomas Edison had announced his intention to invent a light-emitting diode that you could use to illuminate your kitchen. This isn't completely far-fetched: the first examples of light-emitting diodes (LEDs) began to appear as early as 1907. But it wasn't until the 1960's and 70's that useful, visible-spectrum LEDs began to appear, and LEDs haven't been used to light kitchens until very recently. Thomas Edison, had he set out to make a useful, household LED, would have been doomed to failure beacause it would be years before basic science made the necessary technologies possible.

When Richard Nixon declared the conquest of cancer "a national crusade" in 1971, cancer researchers were inevitably set up to be viewed as failures. Although at the time the recent molecular biology revolution led people to think that disease conquest was just around the corner, now we can look back and see that the War on Cancer had no hope of achieving its goals in the 1970's. Scientists are being punished for that hubris now, in the form of misguided news pieces such as Newsweek's current exposé: "We Fought Cancer...And Cancer Won".

Microbes that break down oil and petroleum are more diverse than we thought, suggesting hydrocarbons were used as an energy source early in Earth's history, according to a presentation at the Society for General Microbiology's Autumn meeting.

These microbes can change the composition of oil and natural gas and can even control the release of some greenhouse gases. Understanding the role of microbes in consuming hydrocarbons may therefore help us access their role in the natural control of climate change.

Do you ever think you might have a serious problem because you have to check your e-mail about a hundred times a day? Do you get angry or agitated when you can't check your e-mail or send text messages? Excessive e-mailing and text messaging is just one subtype of potential pathological addiction. And some people suffer from excessive gaming. But even if you check e-mail a hundred times a day and play online games 35 hours a week, don't worry: you're probably not pathological yet. "Carl" is an example of a guy who plays online games 35 hours a week. He's a 51 year old Transportation Planner from California with a friendly, down-to-earth demeanor. After work, he spends about five hours a night fighting monsters, completing quests, and talking to Orcs and Trolls in a game called 'World of Warcraft.' WoW, as it’s commonly known, is a 'massively multiplayer online role-playing game' (MMORPG) with over 10 million subscribers, set in the fantasy Warcraft universe. Carl’s record for sitting in front of the computer playing WoW is three and a half days with no sleep, few bathroom breaks, and a perfect 'level 70' avatar by the end of the campaign.

University of Chicago scientists have discovered how to make magnetic sensors capable of operating at the high temperatures that ceramic engines in cars and aircraft of the future will require for higher operating efficiency than today's internal combustion technology.

The key to fabricating the sensors involves slightly diluting samples of a well-known semiconductor material, called indium antimonide, which is valued for its purity. Chicago's Thomas Rosenbaum and associate Jingshi Hu, now of the Massachusetts Institute of Technology, have published their formula in the September issue of Nature Materials.

A narrow region on chromosome 15 contains genetic variations strongly associated with familial lung cancer, says a study conducted by scientists at Washington University School of Medicine in St. Louis and other institutions in the United States and the United Kingdom.

The researchers found a more than five times higher risk of lung cancer for people who have both a family history of the disease and these genetic variations. The risk was not affected by whether the study participants smoked or didn't smoke.
