• Microscopic flowers exhibit scientists' nano-precision

Harvard researchers have created micro-"flower" nano-fractals by processing silicon compounds dissolved into saline solutions. [QUOTE]CAMBRIDGE—The garden is marvelously lush, with hundreds of blossoming roses, tulips, lilies, and curvaceous, fungi-like plants. But these petals, twisting stems, and finely wrought leaves are invisible to the naked eye: Grown in the lab, this nano-landscape is best seen with an electron microscope. The creation of Harvard researchers, the garden is a demonstration of how simple environmental changes, such as tweaking the temperature, can be used to precisely control the construction of tiny objects and devices—at a scale that is a fraction of a fraction of the width of a human hair. Scientists toiling in this invisible realm are putting their new techniques to aesthetically pleasing purposes to show they work—and capture the public’s imagination. Others have recently made whimsical smiley faces by folding strands of DNA, or constructed Lego-like structures from DNA “bricks” that spell out the alphabet. The ultimate goal, however, is to come up with industrial applications. Researchers envision a new generation of tiny medical sensors and microelectronics, or materials with novel properties, such as interesting ways to interact with light that could enable as-yet-uninvented technologies.[/QUOTE] [URL="http://www.boston.com/news/science/blogs/science-in-mind/2013/05/16/harvard-researchers-grow-garden-nanoscience-delights/E3oYRwy8VMZlz3RDIENpfP/blog.html"]http://www.boston.com/news/science/blogs/science-in-mind/2013/05/16/harvard-researchers-grow-garden-nanoscience-delights/E3oYRwy8VMZlz3RDIENpfP/blog.html[/URL]
You are late.
Luckily I carry around the Plan B pill at all times. You're welcome.
