How do aquatic mammals have enough energy to hunt prey while steeply dropping their heart rate to stay underwater? A new study of dolphins and seals provides clues.
Scientists suspect the current Ebola outbreak started with bats that lived in a hollow tree in Guinea. The outbreak's first victim, a two-year-old boy, often played in the tree.
Scientists have found a compound in soil that can kill the microbes that cause anthrax, tuberculosis and other diseases.
As sea levels rise, many cities will begin to experience frequent and extensive flooding at high tides. In some areas — even Washington, D.C. — such flooding could become a weekly headache.
Questions for Tides Swamp U.S. Cities
New research suggests a type of air pollution — diesel fumes — can affect your health. It inappropriately switches some genes on, while turning off others.
Forty teen researchers have been selected to compete in the Intel Science Talent Search. The event — a program of Society for Science & the Public — will take place in Washington, D.C., March 5 to11.
Bowhead whales can live more than 200 years. The secret to such longevity may lie in the Arctic species’ genes. Scientists recently mapped the whale’s genetic code. They found features that protect the marine mammal against cancer and other problems related to old age.
The common cold infects the nose. Scientists long have known the virus grows better there, but not why. Now, a study finds the body’s defenses simply don’t work as well under the nose’s slightly cooler temperatures.
But be patient. The distant galactic smashup is still some million years away.
To better understand how the body heals wounds, scientists have begun creating computer programs that let virtual cells fight it out. These ‘computer games’ could lead to better medicines.

What visible changes occur, from the moment of injury through the healing process?During reading:1. What is the “mission” of inflammatory cells?2. What manages the process of inflammation?3. Provide an example of a mistake that inflammatory cells might make.4. Define “agent-based modeling.”5. Why is agent-based modeling so helpful in studying complex environments?6. Describe the unexpected behavior that emerged on the virtual battlefield created for the movie.
Rewritable paper could save money, preserve forests and cut down on waste — and all without using any ink.
Field guides often group birds together by similarities in appearance or behavior. But a new study, based on DNA, confirms earlier suspicions that such groupings are only skin-deep.
A new study on mice suggests that when cancer cells strike out from a primary (first) tumor in groups, they have an especially good chance of creating new tumors elsewhere.
White-nose syndrome, caused by a fungus, has killed millions of bats in the eastern United States. Now, scientists show that the disease comes and goes, by season. The finding could help scientists more effectively target any treatments.
New studies and ongoing work highlight why society should save rare livestock breeds — and the part that technology can play.
Most banks store money. But some very special ones store deposits that may prove even more valuable: tissues that could prevent the extinction of breeds and species.
Questions for Livestock: A need to save rare breeds
Figuring out how the brain makes sense of what we read isn’t easy. So scientists enlisted the magical world of Harry Potter. It allowed experts to predict with great accuracy which brain areas would be active in a given part of the story.
