When an antibiotic is consumed, researchers have learned that up to 90 percent passes through a body without metabolizing. This means the drugs can leave the body almost intact through normal bodily functions.

Brussels, 7 December 2010 – Polar research must become an integral part of the European Union's research activities if Europe is to benefit from the dramatically changing face of the Polar Regions, the European Polar Board (EPB) said today at the launch of its strategic position paper on European polar research: "Relevance, Strategic Context and Setting Future Directions."
Television's favourite Time Lord could not exist without his trusty sonic screwdriver, as it's proved priceless in defeating Daleks and keeping the Tardis in check. Now Doctor Who's famous cure-all gadget could become a reality for DIY-ers across the world, say engineers.
Ultrasonic engineers at Bristol University and The Big Bang: UK Young Scientists and Engineers Fair are uncovering how a real life version of the fictional screwdriver - which uses sonic technology to open locks and undo screws - could be created.
Two toddlers are learning the word "cup." One sees three nearly identical cups; the other sees a tea cup, a sippy cup and a Styrofoam cup. Chances are, the second child will have a better sense of what a cup is and -- according to a new University of Iowa study -- may even have an advantage as he learns new words.
EAST LANSING, Mich. — Researchers have long argued that marriage generally reduces illegal and aggressive behaviors in men. It remained unclear, however, if that association was a function of matrimony itself or whether less "antisocial" men were simply more likely to get married.
The answer, according to a new study led by a Michigan State University behavior geneticist, appears to be both.
Mindfulness-based cognitive therapy appears to be similar to maintenance antidepressant medication for preventing relapse or recurrence among patients successfully treated for depression, according to a report in the December issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
Among patients with depression, the presence of many aspects of illness which may be associated with bipolar disorder does not appear to be associated with treatment resistance—evidence against the common hypothesis that some cases of difficult-to-treat depression are actually unrecognized bipolar disorder, according to a report posted online today that will appear in the April 2011 print issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
In conversation, we often imitate each other's speech style and may even change our accent to fit that of the person we're talking to. A recent study in Psychological Science, a journal of the Association for Psychological Science, suggests that imitating someone who speaks with a regional or foreign accent may actually help you understand them better.
AUGUSTA, Ga. – A drug prescribed for Parkinson's disease may also treat restless leg syndrome without the adverse side effects of current therapies, Medical College of Georgia researchers say.
ROCHESTER, Minn. -- Mayo Clinic researchers studied more than 200 children with epilepsy and found that even if the cause of focal-onset seizures cannot be identified and they do not fit into a known epilepsy syndrome, long-term prognosis is still excellent. This study was presented at the American Epilepsy Society's (http://www.aesnet.org/) annual meeting in San Antonio on Dec. 4.
CHICAGO --- Post-traumatic stress syndrome – when a severely stressful event triggers exaggerated and chronic fear – affects nearly 8 million people in the United States and is hard to treat. In a preclinical study, Northwestern Medicine scientists have for the first time identified the molecular cause of the debilitating condition and prevented it from occurring by injecting calming drugs into the brain within five hours of a traumatic event.
NASHVILLE, Tenn. – The season in which babies are born can have a dramatic and persistent effect on how their biological clocks function.
That is the conclusion of a new study published online on Dec. 5 by the journal Nature Neuroscience. The experiment provides the first evidence for seasonal imprinting of biological clocks in mammals and was conducted by Professor of Biological Sciences Douglas McMahon, graduate student Chris Ciarleglio, post-doctoral fellow Karen Gamble and two undergraduate students at Vanderbilt University.
Scientists have shown for the first time that exactly how we see our environment depends on the size of the visual part of our brain.
