At least 15 species have gone extinct in the past 20 years
Slender loris (Loris tardigradus) from Sri Lanka is assessed as Endangered. Between 1956 and 1993, Sri Lanka lost more than 50% of forest cover to human activities, followed by a similar rate of decline in the remaining forest cover between 1994 and 2003. Photo © Anna Nekaris.
The pomegranate tree (Punica protopunica) is a close relative of the cultivated pomegranate and is endemic to Soqotra, Yemen. Although the population is apparently stable at present, it has evidently declined in the past, for reasons that are not certain. It has a severely fragmented distribution and over large areas the tree is absent except for small relict populations with no obvious regeneration. The tree is listed as Vulnerable.

The worlds biodiversity is declining at an unprecedented rate, according to the 2004 IUCN Red List of Threatened Species and a companion study of the data, the Global Species Assessment (GSA). The GSA is the most comprehensive evaluation ever undertaken of the status of the worlds biodiversity. Its findings include the following:
The Red List and the GSA were unveiled today at the opening of the 3rd IUCN World Conservation Congress. Halting the growing extinction crisis will be a major focus of the 3,500 delegates attending the worlds largest conservation gathering.
"This sobering new report should serve as a wake-up call to take immediate action to prevent further species loss," says Russell A. Mittermeier, president of Conservation International and chairman of the IUCN Species Survival Commissions Primate Specialist Group. "It is not too late to act. But we cannot assume that any conservation activities will automatically prevent extinctions. We need better-funded efforts focused specifically on those animals and plants on the brink of extinction, and on those areas where such species are concentrated."

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.
