Airborne drones, mimicking gulls, alter wing shape for agility

The military’s next generation of airborne drones won’t be just small and silent – they’ll also dive between buildings, zoom under overpasses and land on apartment balconies.

At least, that’s what University of Florida engineers are working toward.

Funded by the U.S. Air Force and NASA, UF aerospace engineers have built prototypes of 6-inch- to 2-foot- drones capable of squeezing in and out of tight spots in cities — like tiny urban stunt planes. Their secret: seagull-in

New method for trapping light may improve communications technologies

A discovery by Princeton researchers may lead to an efficient method for controlling the transmission of light and improve new generations of communications technologies powered by light rather than electricity.

The discovery could be used to develop new structures that would work in the same fashion as an elbow joint in plumbing by enabling light to make sharp turns as it travels through photonic circuits. Fiber-optic cables currently used in computers, televisions and other devi

History’s greatest comet hunter discovers 1000th comet

On 5 August 2005, the ESA/NASA SOHO spacecraft achieved an incredible milestone – the discovery of its 1000th comet!

The 1000th comet was a Kreutz-group comet spotted in images from the C3 coronagraph on SOHO’s LASCO instrument by Toni Scarmato, from Calabria, Italy. Just five minutes prior to discovering SOHO’s 1000th comet, Toni had also spotted SOHO’s 999th comet! These comets take Toni’s personal number of SOHO discoveries to 15.

Despite gains, women still face bias in science careers

Despite gains in the training of women scientists and the implementation of programs to help women overcome ingrained barriers, the career path of most women scientists at universities remains a difficult trek, fraught with roadblocks of bias, a sometimes chilly campus climate and the challenge of balancing family and work.

That, in short, is the conclusion of a group of prominent women scientists and administrators, including chancellors and provosts, in an analysis of the issue

Mayo researchers explore reasons for complications with kidney failure patients

Mayo Clinic researchers searching for explanations of high mortality rates among kidney failure patients undergoing hemodialysis are focusing their attention on the use of heparin, a drug used to reduce clotting of the blood.

Their study in the August issue of Mayo Clinic Proceedings is a preliminary look at one aspect affecting the health of patients who undergo hemodialysis. In the study, they found patients who had a higher level of adverse outcomes also had elevated levels of h

Researchers Discover New Route to Hemoglobin Synthesis

Researchers studying zebrafish that die from anemia have discovered a new pathway for the synthesis of heme, the deep red, iron-containing molecule that is a component of hemoglobin and myoglobin. The research suggests that defects in this pathway may be an overlooked cause of anemia in humans.

A research team led by Leonard I. Zon, a Howard Hughes Medical Institute investigator at Children’s Hospital Boston and Harvard Medical School, published its findings in the August 18,
