Because the first extrication drive for Spirit, on Sol 2088 (Nov. 17), stopped as soon as it began due to an exceeded tilt limit, the plan for an extrication drive on Sol 2090 (Nov. 19) will essentially be a repeat of the first drive plan, but with improved rover attitude knowledge. The updated attitude knowledge comes from the rover's measurement of its tilt on Sol 2088. In the Sol 2090 plan, the rover will be instructed to drive straight ahead in two steps. Each step will be a commanded...

With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent, they reported. The technology could have applications in the design of micro-electromechanical systems (MEMS) -- nanoscale devices with moving parts -- and micro-optomechanical systems (MOMS) which combine moving parts with...

NewYork-Presbyterian/Weill Cornell study opens blood-brain barrier to deliver high-dose chemotherapy to malignant brain tumors; may avoid common side effects of systemic chemotherapy Neurosurgeons from NewYork-Presbyterian Hospital/Weill Cornell Medical Center performed the world's first intra-arterial cerebral infusion of Avastin (bevacizumab) directly into a patient's malignant brain tumor. This novel intra-arterial (IA) technique may expose the cancer to higher doses of the drug therapy,...

Laparoscopic Methods Compare Favorably With Open Surgery in Seven-Year NewYork-Presbyterian/Weill Cornell Study of Patients With Notoriously Challenging Cancers of the Rectum Laparoscopic surgery has been used in the treatment of intestinal disorders for close to 20 years, but its benefits have only recently begun to be extended to people with rectal cancer. In a prospective study of 103 patients who underwent straightforward or "hand-assisted" laparoscopic surgery for rectal cancer, a team...

Seismic surveys used for oil and gas prospecting on the sea floor are a disturbance for the rare blue whales, AFP reported. The calls of blue whales were recorded at a feeding ground in Canada's St. Lawrence estuary in August 2004, according to team members Lucia Di Iorio of Zurich University, Switzerland, and Christopher Clark, an acoustics specialist at the Cornell Laboratory of Ornithology in New York. The study, appearing in Biology Letters, a journal of Britain's Royal Society,...

Using a carbon nanotube instead of traditional silicon, Cornell researchers have created the basic elements of a solar cell that hopefully will lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops. The researchers fabricated, tested and measured a simple solar cell called a photodiode, formed from an individual carbon nanotube. Reported online Sept. 11 in the journal Science, the researchers -- led by Paul McEuen, the Goldwin Smith...

U.S. scientists say they have created the tiniest laser since lasers were invented 50 years ago. Researchers at Purdue, Norfolk State and Cornell universities said their achievement might lead to many innovations, including superfast computers that use light instead of electrons to process information, advanced sensors and imaging. The new device -- called a spaser -- is the first of its kind to emit visible light and represents a critical component for possible future technologies based on...
