Oceans Reveal Further Impacts of Climate Change
February 5, 2010 — The increasing acidity of the world's oceans -- and that acidity's growing threat to marine species -- are definitive proof that the atmospheric carbon dioxide that is causing climate change is also ... > full story -
Seabed Biodiversity of the Straits of Magellan and Drake Passage
February 5, 2010 — A study of animals visible to the naked eye and living in and on the seabed -- the "macrobenthos" -- of the Straits of Magellan and Drake Passage will help scientists understand the biodiversity, ... > full story -
New Research Rejects 80-Year Theory of 'Primordial Soup' as the Origin of Life
February 3, 2010 — For 80 years it has been accepted that early life began in a "primordial soup" of organic molecules before evolving out of the oceans millions of years later. Today the "soup" theory has been ... > full story -
Sea Level in Israel Has Been Rising and Falling Over the Last 2,500 Years
