The change in Arctic nature foreshadows the global environment of the future
In Arctic areas, climate change is progressing faster than in any other location on Earth. Researchers at the University of Helsinki have participated in two new studies indicating that the changes are astonishingly fast. Many original species of Arctic areas are in jeopardy, as global warming causes species from southern areas to migrate north, where they occupy the living space of the original species.

Northwestern United States could face more tamarisk invasion by century's end
If future warming trends that scientists have projected are realized, one of the country's most aggressive exotic plants will have the potential to invade more US land area, according to a new study published in the current issue of the journal Invasive Plant Science and Management. The study found that tamarisk -- prevalent today in some parts of the region, but generally limited to warm and dry environments -- could expand its range into currently uninvaded areas.

Young adults may outgrow bipolar disorder
Bipolar disorder, or manic-depression, causes severe and unusual shifts in mood and energy, affecting a person's ability to perform everyday tasks. With symptoms often starting in early adulthood, bipolar disorder has been thought of traditionally as a lifelong disorder. Now, University of Missouri researchers have found evidence that nearly half of those diagnosed between the ages of 18 and 25 may outgrow the disorder by the time they reach 30.
