Ten percent of all bird species are likely to disappear by the year 2100, and another 15 percent could be on the brink of extinction, according to a new study by Stanford University biologists. This dramatic loss is expected to have a negative impact on forest ecosystems and agriculture worldwide and may even encourage the spread of human diseases, according to the study published in the Online Early Edition of the Proceedings of the National Academy of Sciences (PNAS) in December.
"Our projections indicate that, by 2100, up to 14 percent of all bird species may be extinct and that as many as one out of four may be functionally extinct-that is, critically endangered or extinct in the wild," said researcher Cagan H. Sekercioglu of the Stanford Center for Conservation Biology (CCB) and lead author of the PNAS study. "Important ecosystem processes, particularly decomposition, pollination and seed dispersal, will likely decline as a result."
These findings come on the heels of the November 2004 Global Species Assessment by the World Conservation Union (IUCN), which found that 12 percent of all bird species are already threatened with extinction, along with nearly one-fourth of the worlds mammals, one-third of the amphibians and 42 percent of all turtles and tortoises.

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...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
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...
