Sudhir Kumar is trying to answer some of the greatest unanswered questions in biology. How and when did life on Earth evolve? How can scientists identify the genes involved in diseases such as cancer? How does an organism develop from a tiny, fertilized egg into an adult body made up of trillions of cells? Kumar and his team are using new methods and tools to uproot the conventional wisdom of biology. They are giving the tree of life a good shaking.
Origami is the art of folding paper into shapes like animals or flowers. Some origami artists like to challenge themselves by folding models so tiny they could fit on your fingertip. Stuart Lindsay goes even smaller. He makes origami with DNA.
Want a blueprint of your own personal DNA, including every gene in your body? The good news is that scientists know how to make one, thanks to the Human Genome Project. That bad news is that you probably can’t afford it, unless you have $10 million sitting around in your piggy bank. Scientists are working to make gene sequencing less expensive, which will open up new healthcare options.
