A new species of shark that "walks" along the seabed using its fins as tiny legs has been discovered in eastern Indonesia, an environmental group said Friday.

Thai customs on Friday said they had arrested two Vietnamese air passengers after finding more than 100 kilograms (220 pounds) of ivory in their luggage on a flight from Angola.

The haul, which included whole tusks, ivory beads and shaped cubes which could be used for carving, was worth around $500,000, customs said in a statement.

Oregon farmers are moving ahead with plans to start planting their next crop as questions remain about the source of a patch of genetically modified wheat in a farmer's field last spring that threatened trade between the Pacific Northwest and several Asian countries.

Speculation about the origin of the unapproved wheat found in northeastern Oregon ranges from saboteurs to a passing flock of geese. And the U.S Department of Agriculture's Animal and Plant Health Inspection Service said Friday their investigation is ongoing.

The National Oceanic and Atmospheric Administration has launched a review of whether it should take North Pacific humpback whales off the endangered species list.

NOAA Fisheries is responding to a petition filed by a group of Hawaii fishermen saying the whale should no longer be classified as endangered because its population has steadily grown since the international community banned commercial whaling nearly 50 years ago.

A huge canyon twice the size of the longest river in Britain and as deep as the Grand Canyon lies beneath the ice sheet in Greenland, scientists said Thursday.

Prior to the establishment of the ice sheet some four million years ago, the canyon is believed to have been a major pathway for water from the interior of the land mass to the coast.

From a shopping mall in New Jersey to the farm fields of India, experiments show that poverty saps people's brainpower and may lower IQ by 13 points, scientists said Thursday.

The findings in the U.S. journal Science suggest that being poor can drain a person's mental resources, leaving him or her less capable of focusing on other things, like solving problems and controlling impulses.

Earth, Mars, Jupiter and Neptune all have traveling companions — space rocks that share the planets' orbits as they circle the sun.

Now scientists have discovered one that tags along with Uranus. About 38 miles (61 kilometers) wide, the icy rock runs ahead of the planet.

Being short on cash may make you a bit slower in the brain, a new study suggests.

People worrying about having enough money to pay their bills tend to lose temporarily the equivalent of 13 IQ points, scientists found when they gave intelligence tests to shoppers at a New Jersey mall and farmers in India.

A giant "terror bird" deemed to have been one of Earth's top predators after the demise of the dinosaurs was in fact probably a plant-loving herbivore, German scientists reported on Thursday.

Palaeontologists have wrangled for years about Gastornis, a huge flightless bird that lived between 40 million and 55 million years ago.

China has experienced its hottest August for more than half a century, weather authorities said, after a summer heatwave that saw meat cooked on pavements.

A map on the website of the China Meteorological Administration (CMA) shows large parts of central and eastern China, and the western province of Xinjiang, had average daily maximum temperatures of more than 40 degrees Celsius (104 degrees Fahrenheit) between July 31 and August 29.
