The resistance: can viruses save us from drug-defying superbugs?

One-pill-a-day generic AIDS drugs for poor countries are hard to make because each ingredient is patented by a different pharmaceutical company. The Patent Pool provides a way for companies to donate their intellectual property safely.

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.

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.

Concerned with colony collapse syndrome in honey bees worldwide, scientists, farmers and tech companies teamed up in Australia to create a micro-sensor that collects data on the bee's environment.

While critics argue that Naloxone isn't safe for over-the-counter use, some cities have found success distributing Naloxone to community members to help save lives of addicts who overdose. Naloxone can be administered to help those overdosing survive and jump-start the withdrawal process.

In the developing world, intestinal worms stunt physical and mental growth, drain energy, and can inhibit school work for children. Deworm the World is a global campaign that lobbied the Delhi government to regularly distribute deworming pills to school children. The benefits decrease student absenteeism and increase cost-saving measures.

Many different people are inventing health devices for resource-poor settings, but some organizations - like M.I.T.’s Little Devices group - are empowering developing communities and increasing access to healthcare by building medical devices that nurses and doctors in very poor settings can adapt themselves — or kits for making their own, often harvesting parts from toys to cleverly rig up medical equipment. It’s part of a major idea shift, one that’s transforming the design of foreign aid.

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.

Despite significant increases in funding and advances in biomedical research, the rates of new treatments and drugs for illnesses that reach the market every year have plummeted. A group called the Myelin Repair Foundation, along with several other foundations, uses an intensely goal-directed and collaborative method to tackle the bottleneck.

One in five seniors reports cutting back on basics like food or heat to afford prescription drugs - for many, cutting back on medicine led to faster health declines, increased hospitalizations and premature death. Sirum, a new nonprofit, was designed to make it easy for institutions to donate medicines with the assurance that they would be safely transported and dispensed to people who needed them.
