To help detect infectious diseases such as anthrax, HIV, and smallpox, researchers from Northwestern University developed a technique for creating DNA detection probes to "fingerprint" these biological agents. Attached to tiny gold particles are molecules that provide a unique signal (the "fingerprint") when a light is shined on them and a single strand of DNA designed to recognize and bind a target of interest. If a disease target is present in the sample being tested, strands of DNA bind to the appropriate spot on the chip. Corresponding nanoparticle probes latch onto any matches, which are then coated with silver. A laser scans the chip, and signals for the probes are recorded. A unique "fingerprint" can be designed for each biological agent. For more information, contact Chad Mirkin at firstname.lastname@example.org.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
