Sandia National Laboratories (www.sandia.gov) has designed a microdevice that can easily collect and release proteins in aqueous solution in less than one second. The device is a series of gold-coated lines, each line apart by a thickness of one-third of a human hair. It separates proteins from the solution and from each other by electrically heating the metal lines which warms a 4 nm-thick polymer film. The film then changes from a hydrophilic to a hydrophobic state, which enables the film to absorb proteins passing over it. The proteins now separated from the water molecules, are released in a natural cleansing action in the hydrophilic state.
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.
Barnacles and mussels stay attached to ship hulls and rocks because of a very sticky protein glue they secrete, holding on for a long time even underwater. Researchers at MIT took mussel glue as inspiration -- and as an ingredient -- for engineering their own sticky waterproof adhesive.
