Illinois-based study of energy crops finds miscanthus more productive than switchgrass

...he more productive crop will enable researchers to engineer this and other potential bioenergy crops. These developments will increase production options as well as support efforts within biofuel research and industry to work with non-food based biomass resources. ...

MIT, BU team builds viruses to combat harmful 'biofilms'

...As a proof of concept, they used their strategy to engineer T7, an Escherichia coli-specific phage, to express dispersin B (DspB), an enzyme known to disperse a variety of biofilms. To test the engineered T7 phage, the team cultivated E. coli biofilms on plastic pegs. They found that their engineered phage ...

Fat kills cancer

... stem cells from human adipose, or fat, tissue and engineer them into suicide genes that seek out and destroy tumors like tiny homing missiles. This gene therapy approach is a novel way to attack small tumor metastases that evade current detection techniques and treatments, the researchers conclude in the J...

Researchers use adult stem cells to create soft tissue

...al Imaging and Bioengineering to use stem cells to engineer soft tissue, developing a process that should ultimately allow scientists to use a patients own stem cells to develop tissue for facial reconstruction following disfiguring injuries from war, cancer surgery or accidents. The Columbia research team,...

In addition, although the research is still exploratory, scientists are beginning to build nanostructures that mimic complex ...

Invertebrate immune systems are anything but simple, conference finds

...processes in invertebrates might help us to better engineer drugs to tackle these debilitating diseases in humans. Insects can also boost their immune systems ready for a pathogen invasion. Female bedbugs, which are often wounded during mating, enhance their immune system prior to mating in anticipation o...

NJIT professor says certain home shapes and roofs hold up best in hurricane

...t New Jersey Institute of Technology (NJIT). Civil engineer Rima Taher, PhD, special lecturer in the New Jersey School of Architecture at NJIT, spent two years examining the findings of research centers that have studied the best designs and construction materials and methods needed to withstand extreme wind ...

Mutating the entire genome

...chi says it now costs about $10,000 to genetically engineer a mouse with a particular gene or other DNA sequence knocked out. So using existing technology to knock out the estimated 20,000 mouse genes would cost $200 million, and knocking out the roughly 300,000 non-gene DNA sequences in mice would cost $3 bi...

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...r a person with type 1 diabetes, researchers might engineer these cells to become islets of Langerhans, the cellular masses that produce the hormone insulin, which allows the body to utilize sugar, synthesize proteins and store neutral fats, or lipids. "But were a long way from that," Denner warned. Denner...
