Researchers develop technique for bacteria crowd control

...ies of collective bacterial swimming in thin fluid films where the dynamics are essentially two-dimensional and the concentration can be adjusted continuously," explained Igor Aronson, physicists at Materials Science Division, Argonne National Laboratory. "Our results provide strong evidence for the pure h...

Nanotechnology shows promise as next wrinkle fighter

...iscovered that nanoparticles can stop thin polymer films from buckling and wrinkling. It's a new solution to a critical problem as thin films become more important in new technology such as electronic monitors. The cosmetic arsenal to figh...

Ultrathin films deliver DNA as possible gene therapy tool

...d his colleagues have created ultrathin, nanoscale films composed of DNA and water-soluble polymers that al...When used to coat implantable medical devices, the films offer a novel way to route useful genes to exactly where they could do the most good. Lynn, a UW-Ma...

RNA map provides first comprehensive understanding of alternative splicing

...director's cut. In much the same way that numerous films could be stitched together from a single reel of raw footage, a molecular process called alternative splicing enables a single gene to produce multiple proteins. Now a new RNA map, created by a team of researchers at Rockefeller University and the Ho...

Squid-inspired design could mean better handling of underwater vehicles

...mingly inspired by the plots of two classic sci-fi films - may soon allow doctors to guide tiny capsules with jet thrusters through the human digestive tract, enabling them to diagnose disease and dispense medications. Kamran Mohseni, an assistant professor of aerospace engineering sciences, will presen...

Researchers image molecular motor structural changes

...images. The images recorded on electron microscope films are two-dimensional, but three-dimensional structures of the proteins can be calculated by computer image processing. Keiko Hirose, Ph.D., a researcher at Japan's National Institute of Advanced Industrial Science and Technology, performed the elabor...

Like a snail through the intestinal canal

...ndings revealed that muco-adhesives in the form of films provided by far the highest degree of friction. Despite this, there is nevertheless no possibility of movement. A snail uses the exertions of pressure to change the characteristics of the middle layer, and thus lower the degree of friction, in ord...

A reason why video games are hard to give up

...ems emerged--surpass the money made from Hollywood films annually. A range of demographic groups plays video games, and key to understanding their enjoyment is the motivational pull of the games. Four groups of people were asked to play different games, including one group tackling "massively multi...

Finding the right mix: A biomaterial blend library

...s--responded to changes in the composition of thin films made of these tyrosine-derived polymers. In practice, many biomaterials are made from blends of polymers to achieve specific material properties. Optimizing the blend composition is often a difficult and time-consuming task. As the blends gained a hi...

Thermal imaging shatters arousal gender gap myth

...female subjects watched separate sexually explicit films procured from the Kinsey Institute and determined to be sexually arousing to specific genders. They watched the images through special video goggles to minimize distractions. As the subjects responded, the Binik team monitored body-temperatu...

Hidden sponges determine coral reef's nutrient cycle

...d of Curaao using a special underwater camera. The films shot revealed that sponges were the most important inhabitants, followed by animals such as tube worms, tunicates and bivalves. Together they fill more than 60 percent of the cavities. Further the cavities were found to have a surface area eight time...

Breakthrough: Scientists create world's tiniest organic particles

...nwetting Templates, or PRINT, also avoids creating films or "scum layers" that would clump particles together rather than allowing them to be harvested independent of one another."This is in contrast to traditional imprint lithography with silicon, glass or quartz molds where it is difficult to eliminate t...

Disease diagnosis, biodefense among UH chemical research projects
