Is ADHD over-diagnosed? Claims vary, with some people stating that ADHD prescriptions are substituting for parenting and teaching. No matter your opinion, ADHD medication is in greater use than ever and not just for children.

A recent study shows that treatment rates have been increasing in all age groups, and improved identification has contributed to rapidly growing treatment rates for adults. Female patients show the greatest increase of all.

The study, Trends in Medication Treatment for ADHD, revealed rapid growth of ADHD medication use in all demographic groups except seniors, with some groups showing markedly faster rates than others.

What do glowing veggies have to do with a career in science" It just so happens that electrified pickles swimming in metal ions are one example of the type of undergraduate chemistry class demonstration that helps make a future in science a bright possibility, rather than a total turn-off, for many students.

In a commentary in this month’s Nature Chemical Biology, Brandeis University and Howard Hughes Medical Institute (HHMI) Professor Irving Epstein outlines a gathering storm clouding the future of U.S. science and prescribes a series of strategies to help avert a looming national crisis. Epstein says the continued success of U.S. science is seriously threatened by the fact that increasing numbers of undergraduates, particularly the disadvantaged, are writing off a career in science.

In flowers called columbines, evolution of the length of nectar spurs--the long tubes leading to plants' nectar--happens in a way that allows flowers to match the tongue lengths of the pollinators that drink their nectar, biologists have found.

Darwin once proposed a co-evolutionary "race" to explain how natural selection might account for the evolution of very long nectar spurs in flowers, said Scott Hodges of the University of California at Santa Barbara.

Looking into the brain is yielding vital clues to understanding, diagnosing and treating bipolar disorder, according to findings being presented today at the Seventh International Conference on Bipolar Disorder.

The first study, presented by Husseini K. Manji, M.D., chief of the Laboratory of Molecular Pathophysiology at the National Institute of Mental Health (NIMH), suggests that bipolar disorder arises from abnormalities in neuronal plasticity cascades – the complex machinery inside of nerve cells that regulates numerous processes inside the body.

Scientists at the National Institute of Standards and Technology (NIST), along with colleagues at George Mason University and Kwangwoon University in Korea, have fabricated a memory device that combines silicon nanowires with a more traditional type of data-storage. Their hybrid structure may be more reliable than other nanowire-based memory devices recently built and more easily integrated into commercial applications.

Researchers at the University of Pennsylvania School of Medicine have discovered a potential new target for treating type 2 diabetes. The target is a protein, along with its molecular partner, that regulates fat metabolism.
