Google will face big challenges developing a nanotechnology-based test for cancer and other diseases.

After decades of repeated reinvention, the silicon transistor is starting to show its age, and the industry is hunting for alternatives. One option involves a new way of manipulating the properties of a material that the computer industry already uses. If it works, it would lead to computer processors that are not only more energy-efficient but also capable of both computation and memory storage at once.

Google says using a small USB stick to vouch for your identity is more secure than either a password or conventional two-factor authentication.

Lockheed Martin says it will have a small fusion reactor prototype in five years but offers no data.

The furor over a Facebook experiment suggests that few people realize how often Web companies test out new product features on them.

Can an aging corporation’s adventures in fundamental physics research open a new era of unimaginably powerful computers?

Power plants waste huge amount of energy as heat—about 40 to 80 percent of the total in the fuel they burn. A new device could reduce that waste, cutting fuel consumption and carbon emissions by as much as 3 percent and saving companies millions of dollars. (Three percent might not seem like much, but for context, air travel accounts for 2 percent of worldwide carbon dioxide emissions.)

Coconut flesh contains secret ingredients that dramatically enhance its ability to store hydrogen, say material scientists.

A coal plant that opened today in Saskatchewan captures and buries the carbon dioxide it emits—with two significant caveats: it still emits as much carbon dioxide as a natural gas power plant, and the carbon dioxide it buries is being used to force more oil out of the ground.
