A new cancer-detecting tool uses tiny circuits made of DNA to identify cancer cells by the molecular signature on their surface. The circuits work by attaching to the outside of a cell and analyzing it for proteins that are more abundant on some cell types than others. The devices distinguish cell types with higher specificity than previous methods, giving researchers hope their work could improve diagnosis, or give cancer therapies better aim.

Wound healing in mucous tissues during early infection by Simian Immunodeficiency Virus guards some primate species against developing AIDS. Both HIV and SIV provoke an immune response that injures tissues surrounding the intestine; African green monkeys with SIV quickly repair their mucous tissues. This interrupts the disease course and avoids AIDS onset. Stimulating this response might be a way of treating HIV in people.
