  • The Doctor Who Started a Cancer Treatment Revolution

    Immunotherapy has shown promise as an alternative to radiation, chemotherapy, or surgery for treating certain kinds of cancer. By modifying the body’s own immune system to fight lymphoma, Doctor Steve Rosenberg has seen success in clinical trials. The technique has benefitted from recent breakthroughs in genetic engineering that allows for the reprogramming of immune cells.

  • Meet the Giant Rats That Are Sniffing out Landmines

    APOPO, an international nonprofit, has trained Gambian pouched rats to sniff out landmines in countries across the world. These rats have terrible vision, but an amazing sense of smell and have cleared over 13,000 mines since 1997. Training the rats takes about nine months, and includes socializing, teaching them how to walk on a rope in the field, and of course, how to sniff out miniscule amounts of TNT.

  • Can Bats Reduce Nut Farmers' Pesticide Use?

    In California some farms lose up to 10 percent of their crop due to coddling moths. Davis University is measuring the impact bats have on various walnut farms, such as potential savings from reduced insecticide use and crop loss to insects.

  • As wolves rebound, range riders keep watch over livestock

    Wolves in western America were once hunted to near-extinction but have now been reintroduced into certain territories with notable success. More wolves often means more attacks on ranchers' livestock, however, so cowboys are working to track wolf packs by computer to reduce conflicts.

  • In Cambodia, Rats Are Being Trained To Sniff Out Land Mines And Save Lives

    In Cambodia, demining rats have been trained to detect TNT in the ground, effectively identifying unexploded materials like landmines, bombs, and grenades. These two-feet-long Gambian pouched rats have an excellent sense of smell and are trained by Apopo – an international nonprofit – using bananas as a reward for finding TNT. While they are highly effective, they are just one way the region, hit hard by conflict, is attempting to demine its land.

  • Welcome to the world of rhino conservation

    There are only five northern white rhinos left in existence - all in captivity and unable to breed. Researchers work to identify the most valuable solution to rhino poaching in order to prevent the animal from going extinct.

  • Can biomimicry tackle our toughest water problems?

    Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

  • Scientists search Palau's coral reefs for new anti-cancer drugs

    Often it is faster and easier to harvest molecules for medical purposes from nature than to make them in a laboratory. A scientist is looking for cancer-fighting molecules in coral and sponges in the tropical Pacific.

  • Cities in motion: how slime mould can redraw our rail and road maps

    The twenty-first century city is a complex organism, and simulating it to anticipate traffic and transportation congestions can be problematic for urban planning. Researchers around the world from Japan to England have used slime models to simulate traffic and transportation patterns, observing realistic growths, congestions, and re-routing opportunities. Biomimicry demonstrates an unconventional but useful process to understand the pulse of the urban environment.
