Noelle and Darwinia are two adult female leatherback turtles that nest in Gabon, Western Central Africa. The research team has fitted each turtle with a small satellite tracking device, which enables the scientists to monitor their precise movements and observe where and how deep they dive. The tracking began on 7 December 2009 and so far the turtles have travelled 800 miles between them.
Their progress can now be viewed online: www.seaturtle.org/tracking and people can also get the latest news on the turtles by signing-up for dailyemail alerts. Noelle and Darwinia are members of the world's largest nesting population of leatherback turtles, but their environment is threatened. The waters around Gabon are increasingly subject to industrial fishing and oil exploitation, particularly from nations outside West Africa, including countries in Europe.Leatherbacks are of profound conservation concern around the world after populations in the Indo-Pacific crashed by more than 90 percent in the 1980s and 1990s. The International Union for Conservation of Nature (IUCN) lists leatherback turtles as critically endangered globally, but detailed population assessments in much of the Atlantic, especially Africa, are lacking.
The project has been funded by Defra's Darwin Initiative, which draws on the wealth of biodiversity expertise within the UK to help protect and enhance biodiversity around the world.
Dr Matthew Witt of the University of Exeter is a member of the project team. He said: "We are building a high precision model of how these amazing creatures use the seas near Gabon to breed. Our aim is that this will help inform management of fisheries and mineral exploration as well as feeding into ambitious plans to widen the network of marine protected areas in Gabon. It is only by having detailed information on where these creatures go that we can try to protect them."
"Sea turtles are the ancient mariners of the world" said Dr Howard Rosenbaum, Director of the Wildlife Conservation Society's Ocean Giants Program. "Understanding broader migration patterns and use of the nearshore habitat around their nesting beaches is a key component to their conservation."

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
