Researchers at the British Antarctic Survey (BAS) and the University of California, Santa Cruz have discovered that Earth’s last great global warming period, 3 million years ago, may have been caused by levels of CO2 in the atmosphere similar to today’s.

Reporting this week in a leading Earth Science journal, Geochemistry Geophysics Geosystems, the scientists describe how they tested two widely held ideas that attempted to explain the balmy conditions on Earth at that time. Their f

Scientists have long held the belief that the fracturing of the Earth’s brittle outer shell into faults along the deep ocean’s mountainous landscape occurs only during long periods when no magma has intruded. Challenging this predominant theory, findings from a completed study show how differences in mid-ocean ridge magma-induced activity produce distinctly different types of ocean floor faulting. W.

Researchers from the College of Forestry at Oregon State University have developed a new group of adhesives that may revolutionize a large portion of the wood products industry, and have important environmental and economic benefits.

The discovery has already resulted in three pending patents and should lead to a wide range of new products. But it was originally based on the aroused curiosity of Kaichang Li, an OSU assistant professor, who was harvesting mussels one day from thei

The scientists have been able to lure tropical fish – similar to clownfish like film star Nemo – on to artificial reefs by playing recordings of fish and shrimp noises through underwater speakers. A paper in Science journal suggests the technique could be used to restock depleted fishing grounds near reefs, or to populate newly established conservation areas. The study, which focuses on damselfish and cardinalfish in the Pacific Ocean, also warns that ’unnatural’ noises created by shipping and d

A new University of Colorado at Boulder study indicates Earth in its infancy probably had substantial quantities of hydrogen in its atmosphere, a surprising finding that may alter the way many scientists think about how life began on the planet.

Published in the April 7 issue of Science Express, the online edition of Science Magazine, the study concludes traditional models estimating hydrogen escape from Earth’s atmosphere several billions of years ago are flawed. The new s
