The worst drought in 1,000 years
The 1934 drought, during a period in American history known as the Dust Bowl, was the worst in a millennium, a new study finds. While the drought had natural origins, human activities made it worse.

Scientists seek bat detectives
Bats emit high-pitched calls in the night to find their way around. A citizen science project is eavesdropping on these calls to probe the health of ecosystems.

New frog discovered in New York City
This animal could almost be mistaken for the southern leopard frog — until it opens its mouth. The call the males issue has proven unique.

Germs help each other fend off antibiotics
Drug-resistant bacteria can cause persistent infections. A new study finds these germs fight drugs in different ways. And they can swap various compounds, increasing their neighbors’ chances of overcoming the drugs meant to kill them.

Food can make an appetizing science fair project
Many students think they need a laboratory or special equipment for a winning research project. But finalists at the Broadcom MASTERS competition showed food-based research may require little more than your home kitchen

Fish just wanna have fun
Although biologists have observed fish playing before, scientists have now recorded hours of video showing a new type of antic in fish.

How people have been shaping the Earth
We are the dominant force of change on Earth. Some experts propose naming our current time period the ‘Anthropocene’ to reflect our impact.

Coming: The sixth mass extinction?
Species are dying off at such a rapid rate — faster than at any other time in human existence — that many resources on which we depend may disappear.

Rare as a rhino
Most species are rare. Some have always been rare. A problem develops when people are responsible for accelerating a species’ rarity to the point that extinction threatens.

Recycling the dead
When things die, nature breaks them down through a process we know as rot. Without it, none of us would be here. Now, scientists are trying to better understand it so that they can use rot — preserving its role in feeding all living things.

Ebola emerges in the Congo
The Democratic Republic of Congo (formerly Zaire) is where the Ebola virus was first discovered in 1976. This nation has just been hit again by the disease. Scientists suspect this is a new and independent outbreak — not a spread of the epidemic ravaging West Africa.

Ebola treatments and vaccines could be near
Using experimental medicines against Ebola might help to slow or end an outbreak in Africa that has defied efforts to control it.
