Archaeologists armed with top-notch technology have scoured one of the richest shipwrecks of antiquity for overlooked treasures, recovering a scattering of artifacts amid indications that significant artworks may await discovery under the seabed.

Lying 50 meters (164 feet) down a steep underwater slope off Antikythera Island, in southern Greece, the Roman commercial vessel's wreck was accidentally located by sponge divers more than a century ago.

One area in the southwestern United States is spewing vast amounts of methane, a potent greenhouse gas, into the atmosphere far faster than expected, U.S. space agency researchers said Thursday.

Satellite data show more than triple the previously estimated amount of methane is coming from the hot spot located near the Four Corners intersection of Arizona, Colorado, New Mexico and Utah.

Days of heavy smog shrouding swathes of northern China pushed pollution to more than 20 times safe levels on Friday, despite government promises to tackle environmental blight.

Visibility dropped dramatically as measures of small pollutant particles known as PM2.5, which can embed themselves deep in the lungs, reached more than 500 micrograms per cubic meter in parts of Hebei, a province bordering Beijing.

Scientists are moving closer to an artificial hand that can feel: Implanted electrodes allowed some amputees to tell by touch how gently to grasp, letting them pluck fruit without crushing it.

The two men told researchers at Case Western Reserve University that wiring some of their remaining nerves to a robotic arm — albeit only during visits to a lab — felt more like grasping objects with their own hand than with a tool.

Two Americans and a German on Wednesday won the 2014 Nobel Prize for Chemistry for laying the foundations of an ultra-powerful microscope capable of studying tissue down to the molecular level.

Fuel that froze on a Russian Soyuz rocket caused two satellites from Europe's troubled Galileo navigation system to be placed into the wrong orbit in August, an investigation concluded Wednesday.

Stargazers in the Americas and Asia were treated to a lunar eclipse Wednesday, a celestial show that bathed the moon in a reddish tint to create a "blood moon".

An American and a German astronaut spent just over six hours on a spacewalk outside the International Space Station (ISS) Tuesday for equipment repairs and maintenance, NASA said.

Many U.S. coastal communities already struggle with flooding at high tides, a problem that will become "chronic" in the coming 15 years due to global warming, scientists said Wednesday.

A new geological fault capable of generating a 7.1-magnitude earthquake has been found in Wellington, confirming the New Zealand capital's status as one of the world's most seismically active cities, scientists revealed Wednesday.
