Beyond lithium for bipolar disorder

While lithium treatment has proven to be a godsend for many of the two million Americans with bipolar disorder, it is not without its downside. People on the drug may develop hypothyroidism, tremors, cognitive impairment, and excessive thirst and urination and gain weight. However, better treatments for bipolar disorder depend on a better understanding of the still-mysterious mechanism by...

Field of beams - Novel system uses polarized light pulses to reveal crop health

Mathematical models have become invaluable decision-making tools for public health officials. As demonstrated during the United Kingdom's foot-and-mouth epidemic of 2001, models can be useful in two ways: they can reveal the underlying characteristics of an infection and they can allow the comparison of alternative control measures. Often, however, such models make implicit assumptions that may s...

Clock molecule's sensitivity to lithium sheds light on bipolar disorder

Researchers at the University of Pennsylvania School of Medicine discovered that a key receptor protein is a critical component of the internal molecular clock in mammals. What's more, this molecule –called Rev-erb?is sensitive to lithium and may help shed light on circadian rhythm disorders, including bipolar disorder. The findings, which also provide insight into clock-controlled aspects of met...

Scientists to employ Arctic ice and polar bears to protect diversity of world's crops

Scientists at St. Jude Children's Research Hospital have announced that a vaccine they developed a few years ago against one antigenic variant of the avian influenza virus H5N1 may protect humans against future variants of the virus. Vaccines based on this model might therefore be suitable for stockpiling for use during a pandemic (worldwide epidemic) until a new vaccine could be developed specif...

Scientists use an 'ice lolly' to find polar bacteria in their own backyard

To study the bacteria which survive in extreme cold, scientists no longer have to go to extreme environments, such as Antarctic lakes and glaciers. Bacteria previously isolated from polar climates, and have properties which allow them to survive in extreme cold, have been isolated from soil in temperate environments. Professor Virginia Walker and her colleagues at Queen's University, Canad...

Bipolar Risk Gene Identified

Bipolar disorder is otherwise called as maniac-depressive illness. The disease incidence is about one in fifty. But the sad state is that one in six people who suffer from the disorder are likely to commit suicide.// Hence extensive research was done on this disease to identify the gene and also develop various treatment modalities. Dr. Ian Blair conducted a study which revealed the b...
