Antarctic life hung by a thread during ice ages
02-15-2008 · EurekAlert!A report published in the March issue of Ecology argues that the extreme cold and environmental conditions of past Ice Ages have been even more severe than seen today and changed life at the Antarctic, forcing the migration of many animals such as penguins, whales and seals. Understanding the changes of the past may help scientists to determine how the anticipated temperature increases of the future will work to further transform this continent.

- Antarctic plants and animal life survived ice ages
09-27-2007 · EurekAlert!
Springtails, mites, worms and plant life could help solve the mystery of Antarctica's glacial history according to new research published in the journal Science this week.Scientists from British Antarctic Survey and Massey University New Zealand report that of the evolutionary history of Antarctica's terrestrial plant and animal life does not reconcile with current reconstructions of past glacial ice extent going back more than 23 million years.

- Looking for life on Jupiter's icy moon Europa
02-23-2007 · EurekAlert!
If life exists on other planets, it almost certainly will be found where there's water. While many scientists pin their hopes on Mars, UC Berkeley paleobiologist Jere Lipps yearns to probe Jupiter's moon Europa, because its jumbled ice cover reminds him of the Antarctic ice sheets that are home to abundant life on Earth. Lipps and three other scientists discussed the possibilities at the recent AAAS meeting.

- Antarctic marine explorers reveal first biological changes after collapse of polar ice shelves
02-25-2007 · EurekAlert!
Aboard the research icebreaker Polarstern some 52 Census of Marine Life (CoML)-affiliated scientists, led by experts from the Alfred Wegener Institute of Germany, have explored a near-pristine 10,000 sq km Antarctic seabed -- uncapped after several millennia when the Larsen A and B ice shelves disintegrated.

- Ice Ages and rivers may have affected gorilla diversification
12-10-2007 · EurekAlert!
Geography and historical climate change may have both played a major role in gorilla evolutionary diversification, according to a new genetic study by Cardiff University and the University of New Orleans.The collaborative School of Biosciences study shows that the genetic composition of gorilla populations varies across different parts of their current geographic range and that this variation may be tied to Ice Age climate change and river barriers.

- Exploration of lake hidden beneath Antarctica's ice sheet begins
01-15-2008 · EurekAlert!
A four-man science team led by British Antarctic Survey's Dr Andy Smith has begun exploring an ancient lake hidden deep beneath Antarctica's ice sheet. The lake -- the size of Lake Windermere -- could yield vital clues to life on Earth, climate change and future sea-level rise.

- LSU professor looks for life in and under antarctic ice
08-31-2007 · EurekAlert!
Antarctica is home to the largest body of ice on Earth. Prior to approximately 10 years ago, no one thought that life could exist beneath the Antarctic ice sheets, which can be more than two miles thick in places, because conditions were believed to be too extreme. However, Brent Christner, assistant professor of biological sciences at LSU, has spent a great deal of time in one of the world's most hostile environments conducting research that proves otherwise.

- First comprehensive national survey charts sexual behavior among older adults
08-22-2007 · EurekAlert!
The first comprehensive national survey of sexual attitudes, behaviors and problems among older adults in the United States has found that most people ages 57 to 85 think of sexuality as an important part of life, that many men and women remain sexually active well into their 70s and 80s, and that sexual activity was closely tied to overall health, which was even more important than age.

12-04-2007 · EurekAlert!
The age at which children are exposed to peanuts and have an allergic response has dropped significantly over the last decade, despite recommendations that at-risk families avoid exposing children to peanuts during the first three years of life, according to research led by a Children’s Hospital of Pittsburgh of UPMC allergist/immunologist.

A new study contradicts the view that carbon dioxide was responsible for the meltdown that ended the last ice age. Evidence points to springtime Antarctic sun as the main driver.
