Technology on the Agenda

January 21, 2009

Whitehousewebsite Last night, only hours after Obama's inauguration, I visited the White House's .gov web site and, low and behold, it had changed. Changed from the previous staid and information-laden site to a vibrant, interactive entity. Whoa. It shouldn't come as a surprise, really, since the Obama campaign used the Internet to its fullest to organize fundraising and support at the community level like no one else previously. But it sort of feels like a surprise, almost like, hey this guy might actually do what he said he was gonna do. Amazing!

A word that jumps out, and a word he used on the campaign trail, is "transparency." Here is the President's agenda, with details about what he wants to accomplish. On that agenda is a category called "Technology." At first glance, you see that this administration will be embracing science and technology as friend not foe and to use it "to solve our nation's most pressing problems -- including improving clean energy, healthcare costs, and public safety." There are seven major uses listed, each with bulleted action plans below. To summarize:

  • Ensure the Full and Free Exchange of Ideas through an Open Internet and Diverse Media Outlets
  • Create a Transparent and Connected Democracy (there's that word again)
  • Deploy a Modern Communications Infrastructure
  • Improve America's Competitiveness
  • Prepare All our Children for the 21st Century Economy
  • Prepare Adults for a Changing Economy
  • Employ Science, Technology and Innovation to Solve Our Nation's Most Pressing Problems

The web site also has a blog and front door through which anyone from the public can participate and inform government.

Ya know. I'm starting to think he meant it.

Nano in Your Flintstones?

January 15, 2009

Flinstonesvitamins You may not know this, but nanotechnology is making its way into your vitamins and supplements and the FDA may not be able to effectively regulate it. A new report from the Project on Emerging Nanotechnology states that "The ability of the FDA to regulate the safety of dietary supplements using nanomaterials is severely limited by lack of information, lack of resources and the agency’s lack of statutory authority in certain critical areas."

Currently there are about 40 dietary supplements on the market that claim to use nanoscale ingredients, such as calcium, magnesium and silver. You can search PEN's inventory of nanotechnology-based consumer products on the word supplement and see what those products are.

The report, called "A Hard Pill To Swallow: Barriers to Effective FDA Regulation of Nanotechnology-Based Dietary Supplements," offers the following:

  • comprehensive history of FDA’s evolving role with dietary supplements
  • highlights key changes in laws, legislation and resources that have significantly affected the agency’s ability to provide oversight of the burgeoning supplements market
  • provides recommendations to Congress and the FDA for what steps should be taken

The report is free and written in language that is easily digested (perhaps unlike some nanotechnology-laced supplements!)

Nano Dreadlocks

January 13, 2009

Nanobristle DNA has it. Galaxies have it. Beetle shells have it. An essential spiral pattern. How does nature do it? Scientists at Harvard are one step closer to the answer. They've managed to get some tiny bristles to self-assemble into helical shapes (right).

The work will help advance the science of self-assembly and pattern formation and there could be applications of the technique for energy storage.

The scientist started with small bristles that were standing upright like bristles in a brush. They then immersed the bristles in a liquid. As the liquid evaporated, the capillary forces caused the strands to deform and to adhere to one another like braided hair, forming the spiral patterns.

I just think they look cool and want to see more.
