E. coli engineered to produce biodiesel
New research is shedding light on how to alter the genetic makeup of E. coli to produce biodiesel fuel derived from fatty acids.

Graphene may hold key to speeding up DNA sequencing
Researchers have demonstrated that graphene can act as an artificial membrane separating two liquid reservoirs. By drilling a tiny pore just a few-nanometers in diameter, called a nanopore, in the graphene membrane, they were able to measure exchange of ions through the pore and demonstrated that a long DNA molecule can be pulled through the graphene nanopore just as a thread is pulled through the eye of a needle.

LiXEdrom: Innovative measuring chamber for X-ray study of liquid jets
New research demonstrates that liquids can be investigated by X-ray emission spectroscopy without using membranes after all. At the synchrotron source BESSY II, a group of scientists has built a special setup -- the LiXEdrom. It is unique in that the liquid is shot as a jet through the X-ray beam.

Scientists observe single ions moving through tiny carbon-nanotube channel
For the first time, a team of chemical engineers has observed single ions marching through a tiny carbon-nanotube channel. Such channels could be used as extremely sensitive detectors or as part of a new water-desalination system. They could also allow scientists to study chemical reactions at the single-molecule level.
