Buckyballs boost antibody's chemotherapy payload

.... "This is an exciting opportunity to apply novel materials such as fullerenes to generate targeted therapeutics with unique properties," Rosenblum said. "If successful, this could usher in a new class of agents for therapy not only for cancer, but for other diseases as well." While it's possible to attach d...

DOE JGI finishes 100th microbial genome

...mportance to DOE because they can break down plant materials to produce such useful sources of energy as ethanol and hydrogen, and clean up toxic waste sites. We know that microbes can perform these and a multitude of other amazing tasks and with the proper technology we can harness these capabilities." DOE J...

Finding a better way to make biodiesel

...s that would effectively make biodiesel out of raw materials such as used restaurant oils and animal fats ?materials that are much cheaper than soy oil, but also contain free fatty acids that can't be converted to biodiesel by current production methods. Lin has developed a nanotechnology that accurately con...

Mitochondrial DNA sequencing tool updated

...llular power plants," mitochondria convert organic materials into ATP, the cell's energy currency and without which life would cease. As early as the 1920s, scientists uncovered clues that mitochondria might play a role in causing cancer. But like the other DNA in the cell nucleus, scientists lacked the n...

A more powerful and efficient engine for rice: the C3-C4 challenge

...um of scientists will have assembled the tools and materials to begin constructing the prototypes of a C4 rice plant. It will be another 10?5 years after that before the first varieties are available. "Considering the urgent rice production challenges we face, we must start now on this work--there's no time...

Microscopic scaffolding offers a 'simple' solution to treating skin injuries

Chemical in many air fresheners may reduce lung function

...ry illnesses, is to reduce the use of products and materials that contain these compounds." The researchers examined the relationship between blood concentrations of 11 common volatile organic compounds and lung function measures in a representative sample of 953 adults. VOCs are a diverse set of compounds ...

Carnegie Mellon researchers discover new cell properties

...an assistant professor of chemical engineering and materials science and engineering, says that the increased stiffness of the lamina may be caused by mutant proteins self-organizing into ordered structures within the HGPS lamina. "This could make the lamina stiffer and cause fractures in the nuclei," Islam s...

Tetracycline plus teeth equal gray smile

...mbedded deep into the tooth, different restorative materials have to be used to completely cover up the effects of tetracycline. These materials, such as veneers and crowns, have to be placed across all the teeth that show when smiling (typically 8 upper and 8 lower teeth). To place veneers or crowns on all te...

Researchers identify genes in fruitflies that may shed light on human cancer spread
