The Future is Nano:Nano Discussions Subject: Tumbleweeds in the Bloodstream Date: Thu, 28 Oct 2004 16:12:03 -0500 NASA Science News for October 28, 2004 Tiny sensors, shaped like tumbleweed and small enough to fit inside a blood vessel, might one day ride to space insideastronauts' bodies, warning the space travelers when radiation is damaging their cells. This new technology, being developed by NASA-supported researchers, would improve health care on Earth, too.
