+ - CO2-eating light developed that runs on algae-> 3

An anonymous reader writes "Biochemist Pierre Calleja has a solution to reducing carbon emissions that doesn't require us to cut back on our use of carbon-producing devices. Calleja has developed a lighting system that requires no electricity for power. Instead it draws CO2 from the atmosphere and uses it to produce light as well as oxygen as a byproduct. The key ingredient to this eco-friendly light? Algae.

Certain types of algae can feed off of organic carbon as well as sunlight, and in the process produce carbohydrate energy for themselves as well as oxygen as a waste product. Cajella’s lamps consist of algae-filled water along with a light and battery system. During the day the algae produce energy from sunlight that is then stored in the batteries. Then at night the energy is used to power the light. However, as the algae can also produce energy from carbon, sunlight isn’t required for the process to work. That means such lights can be placed where there is no natural light and the air will effectively be cleaned on a daily basis."

+ - Nanotech Dental Fillers Kill Bacteria and Regenerate Decayed Teeth

Submitted by Anonymous Coward
An anonymous reader writes "A team of bioengineers have created the first cavity-filling composite that destroys harmful bacteria and restores tooth enamel lost by decay.

Instead of just limiting tooth decay with conventional fillings, the new material, made with nanotechnology, controls destructive bacteria that co-exist in the natural colony of microbes in the mouth and to rebuild the tooth’s minerals, according to lead researcher Professor Huakun Xu from Maryland University School of Dentistry."

Called TeleHuman, the technology is the creation of professor Roel Vertegaal, director of the Human Media Lab, and his graduate team at the Queen’s University in Kingston, Ontario.

Similar to the Star Trek holodeck, participants can walk around the 3D hologram of the remote person they’re talking to and view them from all sides. More importantly, the system captures 3D visual cues that 2D video miss, such as head orientation, gaze and overall body posture."
