The oceans are loud and getting louder all the time. And marine mammals must live in the din. These animals take different approaches to the noise: Dolphins perform the equivalent of shouting. Humpback whales, when competing with a nearby boat, go silent.
To replace it, NASA engineers powered up a backup gyroscope that had been dormant since early 2011. They were heartened, at first. The gyroscope began spinning despite not being used for 7 1/2 years. However, it sent back readings that were clearly too high.
Imagine this scenario: the brakes fail on a self-driving car as it hurtles toward a busy crosswalk.
A homeless person and a criminal are crossing in front of the car. Two cats are in the opposing lane.
A college-campus-size iceberg spotted on the Antarctic Peninsula margins is upending public expectations of classic Titanic-esque icebergs with sharp spires jutting from the ocean surface.
NASA's famed Hubble Space Telescope is nearly back to normal after a failed orienting tool forced engineers to put it in safe mode earlier this month, the US space agency said.
Bits of plastic have been detected in the faeces of people in Europe, Russia and Japan, according to research claiming to show for the first time the widespread presence of plastics in the human food chain.
NASA has brought Hubble Space Telescope's seven-year old backup gyroscope (gyro) back to life, after the spacecraft entered safe mode due to a failed gyro earlier this month, the US space agency said on Tuesday.
A device made of a brassiere cup fitted with a mobile application, developed by a Mexican student, is designed to be an ally of mammograms for the timely detection of breast cancer in women with very dense breast tissue and in those under age 40.
Salty water just below the surface of Mars could hold enough oxygen to support the kind of microbial life that emerged and flourished on Earth billions of years ago, researchers reported Monday.
A prized caterpillar fungus that is more valuable than gold and is nicknamed "Himalayan Viagra" in Asia, where it is seen as a wonder drug, is becoming harder to find due to climate change, researchers said Monday.
NASA has used certain characters from modern myths such as the "Hulk" and "Godzilla" to name its new set of 21 gamma-ray constellations constructed in celebration of its Fermi Gamma-ray Space Telescope's 10th year of operations.
Is Mercury's core liquid or solid, and why -- on the smallest planet in our solar system -- is it so big? What can the planet closest to the Sun tell us about how our solar system came into being?
For the first time, humans will visit the deepest part of each of the five oceans, plunging to the sea floor using a two-person craft designed to withstand the intense pressures more than 5.5 miles (9 km) below the surface.
Brazilian officials said Friday they have recovered pieces of a 12,000-year-old fossil of a neolithic woman that was among the prized artifacts in Rio de Janeiro's burnt down National Museum.
