Stanford physicists set quantum record by using photons to carry messages from electrons over a distance of 1.2 miles

Featured
Stanford physicists have extended the distance they can demonstrate quantum communications. Stanford News reports on progress using photons to communicate between two electrons through more than a mile of fiber optic cable, an important step toward proving the practicality of quantum networks.

Stanford scientists produce cancer drug from rare plant in lab to benefit human health

Featured
Stanford scientists produced a common cancer drug – previously only available from an endangered plant – in a common laboratory plant. This work could lead to a more stable supply of the drug and allow scientists to manipulate that drug to make it even safer and more effective.

Stanford engineers develop a wireless, fully implantable device to stimulate nerves in mice

Featured
A miniature device that combines optogenetics – using light to control the activity of the brain – with a newly developed technique for wirelessly powering implanted devices is the first fully internal method of delivering optogenetics. The blue glowing device the size of a peppercorn can activate neurons of the brain, spinal cord or limbs in mice and is powered wirelessly using the mouse's…

Dexterous robotic manipulation of alert adult Drosophila for high-content experimentation

Featured
A new lab robot is an example of how clever robotics might speed research and open new fields of study. Stanford News reports on a team of bioengineering scientists that have created a robot with excellent "hand-eye coordination" that can visually inspect active flies and carry out behavioral experiments.

These Microbes "Eat" Electrons to make Methane

Scientists have solved a long-standing mystery about methanogens, unique microorganisms that transform electricity and carbon dioxide into methane. In a new study, researchers demonstrate for the first time how methanogens obtain electrons from solid surfaces. The discovery could help scientists design electrodes for microbial “factories” that produce methane gas and other compounds sustainably.
