A New Take on Microbrewing
Since Babylonian times, a still has provided the means to turn grain, fruit, or vegetables into an intoxicating drink. Today, a still may provide a solution to the more complex problem of how to detect diseases.
California Institute of Technology researchers have crafted the world's tiniest still to concentrate scant amounts of micromolecules for easier detection. This device may help to overcome difficulties in tracking extremely low-abundance molecular biomarkers, which can indicate disease.
"Distillation has been around for millennia, and it's a well-established technology. There weren't many new avenues to develop because it's so well studied," comments David Boyd, a lecturer in mechanical engineering at Caltech and lead author of a paper describing the new approach to distillation in this month's issue of Analytical Chemistry. "But we've created a new space for distillation because you don't need to boil the fluid anymore."

Bacteria in Dish Recreate Predator-Prey Interactions
The hunter-versus-hunted phenomenon exemplified by a pack of lionesses chasing down a lonely gazelle has been recreated in a Petri dish with lowly bacteria.
Working with colleagues at Caltech, Stanford and the Howard Hughes Medical Institute, a Duke University bioengineer has developed a living system using genetically altered bacteria that he believes can provide new insights into how the population levels of prey influence the levels of predators, and vice-versa.
The Duke experiment is an example of a synthetic gene circuit, where researchers load new "programming" into bacteria to make them perform new functions. Such re-programmed bacteria could see a wide variety of applications in medicine, environmental cleanup and biocomputing. In this particular Duke study, researchers rewrote the software of the common bacteria Escherichia coli (E. coli.) to form a mutually dependent living circuit of predator and prey.
The bacterial predators don't actually eat the prey, however. The two populations control each others' suicide rates. continue
Bioreactors Create a Marriage of the Minds
Last summer, ASU researchers Qiang Hu and Milton Sommerfeld were named as part of a team on a grant from the Defense Advanced Research Projects Agency (DARPA) to produce algal oil feedstock as biofuels for conversion to military jet fuel.
Part of this process requires bioreactors to grow the algae. Hu had concepts for bioreactors, but did not have the knowledge or ability to build them himself. That's when he turned to the faculty and students in the Department of Mechanical and Manufacturing Engineering Technology (MMET).
Together, the departments of Applied Biological Sciences and MMET combined their science and engineering expertise to build four different types of bioreactors.
"The relationship is a good mesh between scientists and engineers," says Jerry Gintz, a senior lecturer in MMET and the faculty adviser on the project.
"Scientists do not have expertise in the design and fabrication process necessary to bring their ideas to fruition, and engineers do not have expertise in the science behind the experiment - but they know how to build." continue
Genzyme to Build New R&D Center in Beijing
Genzyme Corp. has announced that it will build a major new research and development center in Beijing. The new facility will be used for research and development activities involving many of Genzyme's key areas of focus, including orthopedics, transplant and immune disease, oncology, endocrinology and cardiovascular disease. The facility, which will feature an innovative green design, will also include laboratory-scale operations for the MACI(R) (matrix-induced autologous chondrocyte implantation) cell therapy and polyclonal antibody operations.
Genzyme's new Beijing facility will be located in Zhongguancun (ZGC) Life Science Park, an area dedicated to academic and government research centers as well as pharmaceutical and biotechnology companies. The 200,000 square-foot building will be constructed with low-impact environmental techniques and methods, and will incorporate a range of environmentally responsible features, including: a living roof to reduce pollution caused by storm water runoff; a solar thermal system that will provide a significant portion of the building's hot water and reduce its energy consumption; and low-flow fixtures to limit water usage.

System Purifies Using Tap Water
Millipore's Milli-Q integral water purification system uses tap water to supply constant-quality Type II (pure) and Type I (ultrapure) water from a single water production unit. The system combines Elix technology with the Milli-Q system to provide users with direct control over water quality throughout the entire purification process.
