Researchers use light to switch on gene expression

Imagine being able to control genetic expression by flipping a light switch. Researchers at North Carolina State University are using light-activated molecules to turn gene expression on and off. Their method enables greater ...

Technology for dogs to assist humans in the home

A team at The Open University is designing dog-friendly technologies which will help animals and people to work together in their homes. They will present the significance of this approach in a paper at the ACM SIGCHI Conference ...

NC State develops more precise genetic 'off switches'

Researchers at North Carolina State University have found a way to "cage" genetic off switches in such a way that they can be activated when exposed to UV light. Their technology gives scientists a more precise way to control ...

Researchers program cells to be remote-controlled by light

(PhysOrg.com) -- UCSF researchers have genetically encoded mouse cells to respond to light, creating cells that can be trained to follow a light beam or stop on command like microscopic robots.

A metal switch to control motor proteins

(Phys.org) —Molecular motor proteins inside the body, called kinesins, are a lot like the motor in your car. The molecular motors convert stored chemical energy into specific conformational changes, which lead to various ...
