Ethanol is widely touted as an eco-friendly, clean-burning fuel. But if every vehicle in the United States ran on fuel made primarily from ethanol instead of pure gasoline, the number of respiratory-related deaths and hospitalizations likely would increase, according to a new study by a Stanford University atmospheric scientist.

Scientists have confirmed the existence of protein in soft tissue recovered from the bone of a 68 million-year-old T. rex. Their results may both change the way that people think about fossil preservation and present a new method for studying diseases such as cancer.

An international consortium of researchers has published the genome sequence of the rhesus macaque monkey and aligned it with the chimpanzee and human genomes. The analysis reveals that the three primate species share about 93 percent of their DNA, yet have some significant differences among their genes.

Scientists are to study spectacular 'night-shining' clouds thought by some to a harbinger of global environmental change. The spectacular clouds, known as noctilucent clouds, will be probed by NASA's Aeronomy of Ice in the Mesosphere mission, or AIM, to determine why they form and how they change. First spotted in Earth's atmosphere in 1885, the clouds have been increasing in frequency in recent decades and may be related to increases in carbon dioxide and methane emissions tied to human activity on Earth.

The Intergovernmental Panel on Climate Change (IPCC) has finalized a new report that assesses the current and future impacts of global warming and explores opportunities for proactively adapting to them.

For most adults dietary fat intake is associated with body mass index (BMI). However, for 13 percent of the Framingham Heart Study population with a specific gene variant, higher dietary fat was not related to a higher BMI. "We have all known people that do not watch what they eat, but usually don't see any effect on their weight," says Ordovas. "This is the first study that enables us to identify this segment of the population using information on this gene.
