Madhava Enros, Mozilla’s user-experience designer, demonstrates the alpha release of Fennec, a Web browser for mobile devices.
A robotic insect is designed to explore rough, alien terrain.
Jascha Franklin-Hodge--cofounder of Blue State Digital, which built Obama’s online social-networking tools--describes how the president-elect’s social-networking strategy made for a well-oiled Election Day effort. Franklin-Hodge also discusses the future of Obama’s e-mail database of "millions and millions" of supporters.
General Electric’s Juan de Bedout demonstrates the company’s software system to improve the electric grid.
In 2007, researchers in Europe studied the health effects of resveratrol, a compound found in red wine. Part of the study included testing mice’s endurance by having them run on a treadmill. Here, the mouse on the right was fed resveratrol, while the mouse on the left was untreated. The treated mouse ran longer and harder than its running mate. This year, researchers conducted a study using a new compound, SRT1720, which targets the same pathway as resveratrol. Again, they tested the mice on the treadmill and found that mice fed this compound showed a similar improvement in performance.
This video shows a patch of engineered heart tissue "beating" in response to electrical field stimulation. Rat heart cells are embedded in a scaffold that mimics the properties of the heart.
A clever flute-playing robot offers an impressive rendition of Flight of the Bumblebee. Its “lungs” consist of a bellow that moves air in and out, and its “tongue” can block air in two places to transition between notes. Its “vocal cords” are a vibrato device that can change vibrations according to the air flow, and it even has elastic “lips” that can control its airstream, changing in width, thickness, and angle as it plays.
Bacteria (fast white spots) swim through human blood in a microfluidic substrate with guidance from an MRI machine. The bacteria swim against the current, past red blood cells (slower white spots).
Following a packed keynote at last week's Mobile Internet World conference, Google's group manager of open platforms, Rich Miner, sat down to take questions from the audience. Here, he comments on the process that Google used to develop Android and on the pressures of an open platform.
At the BioRob 2008 Conference, in Arizona, researchers from around the world gathered to present robots with a wide range of abilities--from mimicking the strange properties of living systems to aiding health outside and inside the human body.
