Alaska researchers seek clues to bird flu
While Alfred Hitchcocks "The Birds" made many of us uneasy at the sight of amassing gulls years ago, today public health officials around the world are beginning to cast an equally uneasy eye toward migratory birds, especially in Alaska, following recent outbreaks of avian influenza in Southeast Asia and, last week, in Siberia.
Alaska is at the intersection of the Asian and North American flyways for migratory birds and scientists say that could provide an unusual mixing ground for the evolution of new strains of bird flu - strains that could spread to lower latitudes and possibly jump to other species, including humans.

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...

What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
