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."

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
