(University of Gothenburg) Having survived for more than 400 million years, the horseshoe crab is now under threat -- primarily due to overharvest and habitat destruction. However, climatic changes mayalso play a role.
Biodiversity decreases towards the poles almost everywhere in the world, except along the South American Pacific coast. Investigating fossil clams and snails researchers show that this unusual pattern originated at the end of the last ice age, 20,000 to 100,000 years ago.

(Ruhr-University Bochum) Starting in October 2010, Dr. Jennifer Strunk will lead a new junior research group in the Laboratory of Industrial Chemistry lead by Prof. Dr. MartinMuhler with a 5-year, 1.18 million Euro ($1.62 million) research grant from the German Federal Ministry of Education and Research.
The Census of Marine Life, a 10-year initiative to describe the distribution and diversity of ocean life, draws to a close with a celebration, symposium and press conference in London. At the press conference, scientists revealed the results of the census, including the discovery of new species, new patterns of biodiversity and more.
In a warming 21st century, tropical forests will be at risk from a variety of threats, especially the conversion to cropland to sustain a growing population.
(DOE/Oak Ridge National Laboratory) Supercomputer simulations at the Department of Energy's Oak Ridge National Laboratory are helping scientists unravel how nucleic acids could have contributed to the origins of life.
(University of California -- Irvine) Freshwater is flowing into Earth's oceans in greater amounts every year, a team of researchers has found, thanks to more frequent and extreme storms linked to global warming. All told, 18 percent more water fed into the world's oceans from rivers and melting polar ice sheets in 2006 than in 1994, with an average annual rise of 1.5 percent.

An unparalleled heat wave in eastern Europe, coupled with intense droughts and fires around Moscow, put Earth's temperatures in the headlines this summer. Likewise, a string of exceptionally warm days in July in the eastern United States strained power grids, forced nursing home evacuations, and slowed transit systems.
