Nanoparticles deliver the goods against cancer, then go

HEALTH

The best way of applying medicines powerful enough to kill cancerous tumours is to ensure that they wind up in those tumours and nowhere else in the body. In a recent Nature Nanotechnology paper, researchers at the University of Toronto point the way to just this kind of targeted delivery, which takes advantage of the properties of gold nanoparticles.

Shedding light on the secrets of plant photosynthesis

ANALYTICAL CHEMISTRY

While untold numbers of plants have carried out photosynthesis for hundreds of millions of years, the nature of this subtle process continues to elude us. Scientists are, however, focusing increasingly sophisticated tools on this problem, raising hopes that this fundamental biological activity will eventually reveal its secrets.

Imaging boost for fuel cells

ALTERNATIVE ENERGY

The same tomographic imaging technique that provides doctors and surgeons with vital views inside their patients is now being adapted to improve the performance of hydrogen fuel cells. Researchers at Simon Fraser University are working with Burnaby-based Ballard Power Systems to apply a new tool for testing and characterizing these devices.

New quantum laboratory opens at University of Waterloo

MATERIALS SCIENCE

The advent of electronic systems that can operate at the level of quantum interactions promises to usher in an era of unprecedented computer processing speed and information storage. Before this revolution can begin, however, scientists need to make the raw materials that will go into this new equipment. This past December, the University of Waterloo opened up a laboratory to do just that.

Persistent Contamination

ENVIRONMENTAL CHEMISTRY

Survival in the Arctic has always been about finding food in a harsh land, as many European­ explorers learned the hard way. Some, such as Roald Amundsen of Norway, made good use of the nutritional wisdom of the Arctic Inuit, whom he met during his exploration of the Northwest Passage from 1903 to 1906. This...
