The mechanisms behind rock-weathering processes can provide vital clues for understanding and reconstructing the history of ancient environments and visualizing the physical conditions in which they were formed, especially climatic situations. Thick ancient coverings of weathered material such as laterites are still the most intensively studied to date. However, little is known about the initial stages of weathering, owing to the rare occurrence of well-preserved examples.

UK scientists and industrialists involved in the NASA, ESA, ASI Cassini-Huygens space mission are eagerly awaiting the data to be received when the spacecraft makes its closest fly-by of Saturn’s largest moon, Titan, on 26th October.

At the time of the closest approach, which is scheduled to be at 5.44 pm BST (9.44 am PDT), the spacecraft will travel a mere 1200km (745 miles) above the surface of the moon at a speed of 6.1 km per second. Confirmation that the flyby has been suc

In an epic research project spanning 14 years and seven continents, a research team based at Brown University has photographed and cataloged nearly 3,000 species of sponges, corals and other shallow water ocean invertebrates from Antarctica to Australia. The key finding: Large-scale forces play a pivotal role in local species diversity. Results are published in the current online early edition of the Proceedings of the National Academy of Sciences.

In a groundbreaking, globetr

Antarctica and climate change – representatives of 32 nations decide on research focus programmes for the exploration of Antarctica

Exploration of Antarctica is of great significance in the context of discussions about global climate change. For this reason, the international Antarctic research community has just re-defined and coordinated its scientific programmes within a recent meeting of the international committee responsible for Antarctic research coordination SCAR (Scient

Forest fire particles come to town

Researchers at the University of Toronto have detected migratory pollutants from a forest fire in Quebec and even particles from a sandstorm in the Sahara in Toronto air, findings that could someday give regulatory agencies an idea of who is contributing to the pollutants found in urban air.

“It’s a bit of detective work,” says Greg Evans, a professor in the Department of Chemical Engineering and Applied Chemistry. “We happened

French and Australian scientists resume measurements of Antarctic waters south of Australia this week to assess their capacity as a massive oceanic sponge to absorb greenhouse gases and store them away for hundreds or perhaps thousands of years.

France and Australia have a joint research program taking measurements from the Antarctic supply ship L’Astrolabe during its voyages between Hobart and the French base at Dumont D’Urville. L’Astrolabe, equipped with a full
