Searching For Meaning In A Cheap Toaster

Carl Sagan once said that if you want to make an apple pie from scratch, you must first invent the universe. In his book The Toaster Project, author and artist Thomas Thwaites describes his effort to build a cheap plastic toaster from scratch, and what the project taught him about material goods, self-reliance, international commerce, and globalization.

Using DNA To Shape Nanostructures

Chemists and materials scientists are trying to learn to build ultra-small, precisely ordered structures for use in optics, electronics, and other applications. Writing in the journal Science, Chad Mirkin and colleagues describe a way to use snippets of DNA to tailor the shape and size of crystal structures, tweaking them to fit specific uses.

Decoded DNA Reveals Details Of Black Death Germ

While the results are a technical tour de force, the researchers did not find any genetic feature that could explain why the Black Death was so virulent. In fact, the germ behind the medieval plague isn't much different from the one that causes bubonic plague today.
