Since November, a physics experiment called the Cryogenic Dark Matter Search (CDMS II) has been looking for components of dark matter, the primary “stuff” of which the universe is made. Conducted from the Soudan Underground Mine in northern Minnesota, the search is for postulated dark matter particles called WIMPS--weakly interacting massive particles. So far, the experiment has found no WIMPs, but neither has it found contamination from stray neutrons. CDMS II member Priscilla Cushman, a physics professor at the University of Minnesota, is delighted.
“It is actually very satisfying to see nothing on our first run because it establishes the degree of background rejection we have been able to achieve,” said Cushman. “We hope the next run will reveal the elusive dark matter particle.”
The results are being presented at a meeting of the American Physical Society on May 3 and 4 in Denver by Harry Nelson and graduate student Joel Sanders, of the University of California-Santa Barbara, and Gensheng Wang and Sharmila Kamat, of Case Western Reserve University.

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...
