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."

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
