Australia's koala population has been hit hard by two rapidly spreading diseases: chlamydia (a sexually transmitted infection) and a retrovirus similar to HIV. Scientists are working to develop vaccines, while lay citizens help care for sick koalas. Biologists say the epidemics, combined with other threats like habitat loss, pose a serious threat to the species.

In this interview with The World's Marco Werman, NOVA Producer Miles O'Brien describes how surveillance footage played a key role in cracking the case of the Boston Marathon bombings. But as O’Brien discovered in the course of reporting the NOVA special “Manhunt—Boston Bombers,” other cities, especially New York City, have surveillance camera networks that are far more advanced than Boston’s hodgepodge system. O’Brien recounts just how powerful those systems are and what that may portend for privacy in the future.

The residents of Australia's Northern Territory share their land with one of the deadliest predators on the planet—the saltwater crocodile. Getting humans and these fearsome reptiles to coexist isn't easy. But a government program called "Be Crocwise" is doing its best to keep the peace.

An Oxford University researcher will soon test whether applying an electric current to part of the brain can help children learn math—an effect previously demonstrated in adults. Parents are already lining up for access to the device. But is the technique safe? And is this an ethical way to improve a child’s performance in school?

What makes a dog bold or shy, eager or sullen? The Veterinary University of Vienna's Clever Dog Lab aims to find out with the help of some 600 Austrian dogs that owners volunteer for experiments. The results could improve the training and selection of dogs that serve society, from helping the disabled to assisting the police.

The last place you'd expect to find a new treasure is where everyone has been looking for centuries. Yet in Europe, home to history's greatest taxonomists, professional scientists and amateurs are scouring the countryside for new species—and finding them at an astonishing rate.

People around the world spend an estimated 3 billion hours playing computer games every week. That might seem like a colossal waste of time, but scientists are starting to harness some of that effort to solve vexing problems in biology. Take, for example, a game developed by a pair of scientists in Canada.

British scientists have developed a genetic test for a disorder that causes people to emit an unusual body odor: The gene causes sufferers to smell like rotten fish. For those who have been ostracized—shunned by friends and unable to hold jobs because they are perceived as unhygienic—the test offers some solace. But one patient says the genetic discovery has not changed his life as much as he had hoped for.

Sight, sound, touch, smell, taste. We interact with the world and navigate through it thanks to our senses. But what if we could add to that repertoire? A British scientist and a small group of enthusiasts are exploring ways to do just that.

Hurricane Sandy has renewed the debate over climate change in the United States, and two high-profile reports released since the storm have made it clear that without big changes we're headed for an extremely serious climate disruption. Reporter Sam Eaton takes a look at what would have to happen to avoid the most catastrophic effects of global warming.

On July 4, 2012, scientists at CERN used the word "discovery" to describe the results of experiments designed to prove the existence of the Higgs boson, a particle that gives mass to the universe. Host Marco Werman of PRI's The World gets a down-to-earth layman's analogy for what it means to say that a particle "gives mass," finds out why it's called the "God particle," and hears from a member of one of the teams that found the new particle, Jordan Nash of Imperial College London, on what this means for him personally and for physics.

Cornering the Higgs

There's a lot more to the oceans than salt and water. Many other ingredients make up the rich broth that sustains marine life and helps regulate the Earth's climate. But where do those ingredients come from? To answer that question, French geochemist Catherine Jeandel has collected seawater from all over the world and is examining it for elemental clues.

Could climate change be contributing to extreme weather events like Hurricane Sandy? Jennifer Francis, a climatologist at Rutgers University in New Jersey, believes that may be the case. In fact, her research shows that Arctic warming may have contributed to many of the extreme weather events of the past few years. Sam Eaton reports from New Jersey.

After a crime or terrorist attack, authorities looking for the perpetrators may need to review many hours of surveillance video—in just minutes. But how can they speed up the video without speeding up the action? That's where "video synopsis" can help.
