g Stars - An ancient galaxy has broken the record for the most distant point in the sky known to date, with its light taking roughly 13.1 billion years to reach Earth. See article.
g Abodes - Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide. See article.
g Life - Although ammonites have been extinct for 65 million years, newly published data based on 35 years of field work and analysis is providing invaluable insights into their paleobiology. Ammonites, shelled mollusks closely related to modern day nautilus and squids, inhabited the oceans for nearly 350 million years. Specimens found in the rock record of the ancient seaway that covered North America during the Cretaceous Period demonstrate that these animals thrived at cold methane seeps at the bottom of the sea, consumed small prey, and often survived predation attempts. See article.
g Message - It's great to see the reputable National Geographic take the search for extraterrestrial life seriously. See article. This article is from 2004.
g Cosmicus - Physicists at the University of California, Riverside have taken an important step forward in developing a "spin computer" by successfully achieving "tunneling spin injection" into graphene. See article.
