Researchers at the National Institute of Standards and Technology (www.nist.gov) have developed a new method to produce uniform, self-assembled nanocells for drug therapies, such as chemotherapy, in which dosage depends critically on the size of the nanocells. The new method uses micrometer-size channels etched into a device to produce self-assembled liposomes—a type of artificial nanocell—of specific sizes from 100 to 240 nm. A stream of lipids dissolved in alcohol is directed at an intersection of two channels while a water-based liquid containing medicines or other substances is sent toward the lipid stream from two opposing directions. Self-assembled nanocells are formed when the lipids surround the water rather than mixing with it.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
