CO2 levels tightly linked with climate change over past 420 million years
(03/28/2007) New research shows that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) have been relatively consistence for at least 420 million years, suggesting that presently rising levels of carbon dioxide resulting from fossil fuel use will indeed produce higher temperatures in the future.
Dinosaur extinction didn't produce current mammal evolution
(03/28/2007) A new Nature study argues that the demise of dinosaurs did not fuel the rise of mammals. Devising a new tree of life for 4,500 species of mammals using molecular evolutionary trees, an international team of researchers challenges the prevailing hypothesis that a mass extinction of dinosaurs 65 million years ago played a major role in the diversification of mammals.
Lightning may be used to predict volcanic activity
(03/28/2007) While it has long been known that volcanic eruptions can produce vigorous lightning, there are few direct observations of the phenomena, states the article. Following the initial eruptions of Jan. 11 and 13, 2006, two of which produced lightning, two electromagnetic lightning detectors were set up in Homer about 60 miles from Augustine. A couple of days later, the volcano erupted again, with the first of four eruptions producing a "spectacular lightning sequence."

Extinction, like climate change, is complicated
(03/26/2007) Extinction is a hotly debated, but poorly understood topic in science. The same goes for climate change. When scientists try to forecast the impact of global change on future biodiversity levels, the results are contentious, to say the least. While some argue that species have managed to survive worse climate change in the past and that current threats to biodiversity are overstated, many biologists say the impacts of climate change and resulting shifts in rainfall, temperature, sea levels, ecosystem composition, and food availability will have significant effects on global species richness.

Prehistoric lizard glided through air using ribs
(03/19/2007) An extinct species of lizard used a wing-like membrane supported by the animal's elongated ribs for gliding through the air according to Chinese researchers. The 6-inch (15.5 cm) lizard, found in the Liaoning Province of northeastern China, lived during the Early Cretaceous period. The specimen is described in the early online edition of the journal Proceedings of the National Academy of Sciences (PNAS).
Genetically engineered mosquitoes fight malaria
(03/19/2007) Globally, governments are spending hundreds of millions of dollars annually to reduce the impact of the malaria, a mosquito-borne disease that affects around 400 million people each year and kills one to three million die. While most of the focus to date have been on developing drugs that boost immunity to malaria or counteract the malaria parasite once it is in the victim's bloodstream, scientists have now developed a treatment that focuses on the mosquito itself. The research, described in the early online edition of the journal Proceedings of the National Academy of Sciences (PNAS), uses a genetically engineered strain of malaria-resistant mosquitoes to out-compete natural mosquitoes when fed malaria-infected blood.
