Simulations unravel outer membrane transport mechanism

...s through the barrel. (Click on the link below the image of the system to watch the results of the simulation.) A second simulation exerted a force near the center of gravity of the luminal domain, pulling it out of the barrel in one piece. This required an enormous input of energy, however. “The for...

Envisat captures first image of Sargassum from space

...This appears to be the first report of a satellite image of Sargassum," Gower said. "It is usually associated with the area of the North Atlantic known as the Sargasso Sea after the Sargassum encountered there by early explorers. Our observations of Sargassum lines extending over large areas of the Gulf sh...

Catching cancer's spread by watching hemoglobin

...e deadliest form of skin cancer. The technique can image blood vessels up to a millimeter below the surface. Looking at blood vessels just below skin growths would be very useful for distinguishing between malignant and benign skin tumors, and would remove the critical need for skin biopsies, which is espe...

...ersity's colors. This, Moeller said, is a striking image of the technique's ability to do chemistry at specific electrodes. "What electrochemistry does best is to reverse the polarity of things," Moeller said. "It takes things that are electron-poor and makes them electron-rich and vice versa; it can take ...

Fast and slow -- How the spinal cord controls the speed of movement

... microscope with lasers allowed the researchers to image the cells at very high resolutions. Using this set up, they watched nerve cells light up as the animals moved at different speeds. While no one knows how this pattern relates to other vertebrates, the research opens a door toward basic understandi...

In this study, Bearden and colleagues at UCLA used computer analysis to analyze brain scans collected by collaborators at the University ...

McBride shows DNA detective work with paper-eating bacteria that 'glide'
