In terms of sheer numbers of cases, the current Ebola outbreak in West Africa is the biggest ever recorded. But analysis shows that the disease is not spreading as quickly as some diseases have in the past, which gives some hope that it might soon be contained.
As a boy growing up in Cameroon, Christian Happi's heroes were American biologist James Watson and English physicist Francis Crick. His dream was to work in genetics. Now he's doing the work he finds most meaningful. Happi's lab was among the first to identify the presence of the deadly Ebola virus in Nigeria.
We've all seen black carbon in the form or the soot or smoke that rises from coal fires or cooking stoves. It's one of the biggest sources of greenhouse pollution on earth, and researcher Tami Bond won a MacArthur Fellowship to help chase black carbon sources around the world — and stop them.
First, electron microscopes let scientists see into the atomic world like never before. Now, some of those scientists are able to create their own microscopic landscapes using new chemical technologies. And they're hoping NanoArt is on the verge of going mainstream.
In the Pacific Ocean, west and south of Hawaii, is what was until recently one of the largest marine sanctuaries on earth. Now, however, it has been expanded — to nearly six times its original size. And scientists are thrilled.
When India celebrated the success of its first Mars mission, a photo of middle-aged female scientists draped in saris became the viral face of that triumph. But that doesn't mean female scientists face an easy path, and Rhitu Chatterjee says much more needs to be done for gender equality.
The grim forecasts for the growing Ebola epidemic shouldn't spark panic, says one geneticist. Instead, the response to the outbreak calls for worldwide collaboration and a globally crowdsourced battle plan.
The differences between developed countries like the US and rising powers — and polluters — like China and India are well-known. But there's also a major gulf between Americans and Europeans on climate policy that is hurting efforts to reach a large-scale climate agreement.
The news is full of viruses these days, from Ebola and West Nile to electronic versions that let hackers steal identities and credit card information from major retail stores. But is the comparison between computer viruses and biological viruses even useful anymore?
Plants have senses that put humans to shame. Not only do they hear (yes, it's true) and smell, they can also sense the presence of water, and even an object in their space. Now new research suggests that plants can actually learn and remember.
Italy is a fiercely anti-GMOs. It's one of a handful of countries to ban them outright. But European law is trumping them, and it has opened a window for one Italian farmer who is growing GMO corn anyway.
Scientists say a massive ice sheet in Antarctica is starting to collapse. It's not going to slide into the ocean over night, but rather over centuries. Still, it will fall, scientists say. It's gotten to the point it can't be stopped — and that means rising sea levels.
Half of North America's 650 bird species may be forced to change their current habitats because of climate change or perish — including the bald eagle and the common loon. A new Audubon Society study produced maps to show people which of their local birds are at risk.
The new NOVA special, "Vaccines: Calling the Shots," explores the lingering global resistance to vaccination campaigns. Case studies from around the world explain just how bad the impact can be when groups opt out of childhood shots.
Scientists are often depicted as skeptical of God — atheists who believe only what they can prove. But science writer Amir Aczel says science doesn't actually disprove God, and there are at least a handful of scientific phenomena that suggest an outside force acted to create the universe.
The answer to today's Geo Quiz is Basel, Switzerland. The city was home to Swiss chemist Albert Hofmann, who died yesterday. The World's David Leveille reports that Hofmann's discovery of LSD remains controversial.
Turns out that animals lie. At least fiddler crabs do, according to a new study by Australian scientists. The BBC's Matt McGrath tells anchor Lisa Mullins how growing a fake claw helps male fiddler crabs win mates and avoid fights.
The answer to today's Geo Quiz is the Egyptian city of Luxor located at the site of the ancient city of Thebes. Mummies from the Brooklyn Museum had a CAT scan this week. Lisa Mullins gets the story from the museum's Egyptian art curator Edward Bleiburg.
Dubai opened the Arab Peninsula's first metro system today. It's to become the world's longest driverless train system. Anchor Marco Werman speaks with John Alexander Smith, professor of Architecture and Interior Design at American University in Dubai.
Economists and analysts track just about everything to gauge how the economy is doing. Some analysts just focus on one product- can we really learn how the economy is doing by looking in our underwear drawers? The World's Jason Margolis reports.
As we've reported on before, Tasmanian devils could be wiped out by a rare ? and mysterious ? form of cancer. Scientists have now made progress in solving that mystery, and host Jeb Sharp speaks with one of them.
