California’s coastal redwoods can absorb nutrients and moisture from the thick fog that rolls in from the Pacific. And fog patterns give us clues about how the iconic trees might respond to a changing climate.
In her new book, "This is Your Brain on Parasites,” author Kathleen McAuliffe describes the numerous links between animals and parasites, how they've co-evolved, and how parasites may actually affect the behavior of humans and other animals.
NASA’s Dawn spacecraft already racked up several firsts during its seven-year flight from Earth, and now it's the first-ever spacecraft to orbit a dwarf planet. Scientists are hoping its yearlong stay at Ceres, in the asteroid belt between Mars and Jupiter, will help reveal clues about how Earth got its water.
Time is running out for thousands of people in Africa who are in danger of contracting Ebola. A cure or vaccine will not come in time to prevent many more infections and possible deaths. And now a second case has been diagnosed in the US. Perhaps the only answer is a rapid diagnostic test that can quickly identify those who are ill and those who are not.
Black holes may be exotic, but they are hardly rare. Every galaxy has one, including ours. But it's tough to look at and study black holes since their gravitational pull is so powerful light can't escape from them. But thanks to a new telescope that captures high-energy x-rays, NASA scientists are peering at their edges, confirming Einstein's theories, and may have gotten the first glimpse of a new kind of black hole.
Young people will need to understand climate change to make informed decisions in the future. But in many school districts in the US, students receive little or no scientific information about it. Teachers who do try to bring climate science into the classroom can find themselves in trouble.
