With record resolution and sensitivity, tool images how life organizes in a cell membrane

...ystals before analysis. Geologists, cosmologists, materials scientists and engineers covet the machine for characterizing hard materials, such as rocks, space dust, polymers and nanoelectronics. But in the last five years, biologists have become interested in employing it to characterize components of biologi...

Iowa State researchers improving plastics made from corn and soy proteins

...hael Kessler, an Iowa State assistant professor of materials science and engineering who's also working on the project. Those clay platelets need to be separated and mixed evenly throughout the plastic to be much good as a reinforcing agent. The researchers are turning to high-powered ultrasonics ?high-freq...

African wetland managers armed with new technology

...encies and take over the process. All the training materials were consolidated on a CD and given to all African end users at the close of the session. In addition, all attendees received an ESA TIGER initiative training kit. GlobWetland makes up an integral part of the TIGER initiative, which focuses on the us...

Important gene controlling tree growth and development found

...ved pulp and paper production, better construction materials and enhanced bioenergy production. Trees are extremely important for life on earth. They are often a dominating part of the ecosystems and 30 per cent of the earths landmass is covered with forests. Trees produce many important products for mankind ...

Nanotubes used for first time to send signals to nerve cells

...ir, are already famed as one of the most versatile materials ever discovered. A hundred times as strong as steel and one-sixth as dense, able to conduct electricity better than copper or to substitute for silicon in semiconductor chips, carbon nanotubes have been proposed as the basis for everything from eleva...

Producing bio-ethanol from agricultural waste a step closer

Diabetes research takes wing thanks to long-lived fruit fly

...ling molecules known as free radicals zing through materials and run roughshod over anything in their way, including vital proteins and DNA. It's a major reason why generally our bodies falter as we age ?we're literally dinged to death by free radicals. While scientists knew that JNK in a fly cranks up the an...

Biological motors sort molecules one by one on a chip

...protein factories. The necessary transportation of materials within the cell occurs across a network of microtubules: long, tubular-shaped proteins that extend in a star-shaped formation from the nucleus of the cell to the walls of the cell. Molecular bio-motors, such as the enzyme kinesin, can walk in small s...

No cell walls, no new cancer cells

Cancer cells, like houses, need building materials for their walls. And as with a house, the cell wall needs to be built at just the right moment to protect and allow the construction of internal components. A team from the Uppsala Branch of the global Ludwig Institute for Cancer Research (LICR) has ...

DOE publishes research roadmap for developing cleaner fuels

...better processes by which to break down cellulosic materials into sugars, and optimizing the fermentation process to convert sugars to ethanol. Cellulosic ethanol is derived from the fibrous, woody and generally inedible portions of plant matter (biomass). The focus of the research plan is to use advances in...

One-dimensional diffusion accelerates molecular motors

...rast to most other motor proteins, which transport materials over long distances along microtubules. The researchers were able to show that the protein reaches the position via a random, one-dimensional diffusion movement along the microtubule, until it locks into place at its end (Nature, May 4, 2006). This d...
