The World Health Organization says the devastating birth defects and brain disorders linked to the Zika virus are an international health emergency.
Vegetable oils can make plastic fibers stronger. And the process is safer and better for the environment than other detanglers.
This glossary provides definitions and audio clips to help you learn and pronounce even the toughest science terms.
This step-by-step series from the Eureka! Lab blog explains how anyone can do a research project and do it right.
Geophysicists are discovering how weapons shake, rattle, and roll the Earth. What they’re learning might one day help win wars.
A new device with lithium and silicon electrodes uses chemistry to generate electricity as it bends back and forth.
Zika virus has been in Africa and Asia for decades. But is has now spread to the Americas. And it may cause a devastating birth defect.
Oil and tiny pores prevent the feathers on some penguins from freezing. The discovery could inspire new ways to keep ice off of airplane wings.
Long-lasting pollutants may threaten marine mammals and human health. To find those pollutants, scientists are sampling blubber, then running the fatty material through new types of tests.
Since the 1970s, microbiologists have been saying bacteria outnumber human cells in our bodies by about 10-to-1. A new analysis says that old number was a “fake” fact — and gross exaggeration.
The dense hair that keeps sea otters warm in frigid waters may inspire development of “furry” wet suits for scuba divers.
A giant planet, perhaps 10 times Earth’s mass, may be orbiting the sun from a great distance. Its existence, orbit and size are all surmised, based on strange effects seen in objects within the distant Kuiper Belt.
HIV rates in people ages 13 to 24 are increasing, but few teens and young adults are being tested for the virus.
The ATLAS telescope could be a last-minute warning system for asteroids just days away from hitting Earth.
Spurred by global warming and a “super” strong El Niño, 2015 went into the books as the warmest year since record-keeping began — and that was 1880.
The behavior of hundreds of genes can identify a viral infection, a new study finds. That could help doctors determine treatment for a sick patient.
Spiral wounds on dead seals led experts to blame boat propellers. But cameras exposed another source: One seal species was killing another.
Because tanning beds can increase the risk of skin cancer, the FDA has proposed banning their use in the United States by anyone under 18.
Many whales become entangled in the gear that fishing boats use to catch fish and shellfish. Such debris can have dire impacts on the big mammals.
A former football player who died in his mid-20s had serious Alzheimer's-like damage that doctors are now linking to repeated concussions.
For Earth’s earliest inhabitants, a bubble on the beach would have been the next best thing to a safety blanket.
The conventional idea for how black holes form would not easily allow for huge ones to develop in the early universe. Yet they did. Now a scientist offers a new view: galaxy mash-ups!
Climate change is melting old sea ice in the Arctic. Now, younger, thinner ice is migrating far and fast, taking pollutants with it.
Children and teens with asthma, allergies or other autoimmune conditions tend to be overweight and show symptoms of heart-disease risks, a new study finds.
U.S., Russian and Japanese scientists have just been credited with official discoveries of elements 113, 115, 117 and 118. Next up: Naming them.
Two vast blobs in Earth’s lower mantle could result from a “trainwreck” of ancient colliding tectonic plates.
A false “dinner bell” can safely distract hungry whales from stealing fish from commercial fishing lines, new research shows.
When the sun is right near the horizon, such as at sunset, its light travels through the most atmosphere. When there’s also plenty of water in the air, this can rob colors from a rainbow, scientists now report.
Rocks that formed during ancient mass-extinction show that the oceans back then had become very warm. That was the last time Earth spewed carbon dioxide into its atmosphere at a rate similar to what is happening today.
Scientists have found indirect evidence that the dense cores of dead stars are making ripples in space, known as gravitational waves. These waves have been predicted but never yet directly “seen.”
Dogs don’t know their own reflections in a mirror, but they do recognize themselves from the scent of their own urine, a new study finds.
Engineering safer soils for urban growers can reduce the risk of lead exposure and let low-income families enjoy more fresh fruits and vegetables.
