Recycling meets reality

Modern industry has made great strides in turning trash into tomorrow’s new products, but the process is still a long way from perfect. New technologies can help. Plus, updates on chemical recycling, design for recycling and dirty recycling.

At San Diego’s Frozen Zoo, a chance for animal immortality

The cryobank is a rich source of genetic knowledge of hundreds of creatures. It may one day be used to bring endangered species back from the brink and deepen the gene pool of wild populations.

Controlled burns won’t save all of California from wildfire

There are two types of wildfire in the state, and they’re on the rise for different reasons. Each needs a distinct management approach, a researcher says.

Will the food of the future be genetically engineered or organic? How about both?

Feeding the planet — now and tomorrow — is no small task. Plant biologist Pamela Ronald says sustainability means using every tool in the toolbox.
