New photos gleaned by the Mars Express spacecraft in orbit about the red planet have failed to shed any light on the origins of an "enigmatic" elongated crater named Orcus Patera.

A team of 86 global scientists sequence the genetic code of the Golden Delicious apple for the first time.

The dinosaurs were wiped out by at least two meteorite impacts rather than a single strike, say scientists.

A scheme to generate renewable energy by simply pulling electric charge out of humid air sparks debate amongst scientists.

Astronomers have discovered a planetary system containing at least five planets that orbit a star called HD 10180, which is much like our own Sun.

The hunt for aliens should allow for the fact that ETs may be thinking machines rather than like us, a leading researcher says.

A maternal ancestor to all living humans called mitochondrial Eve likely lived about 200,000 years ago, at roughly the same time anatomically modern humans are believed to have emerged, a new review study confirms.

Science editor Alan Boyle's Weblog: "Packing for Mars" tells you everything you always wanted to know about sex, poop and vomit on the final frontier. But that's not the point of the story. The point is how to get humans ready for Mars.

Scientists from the University of Calgary's Faculty of Medicine have been involved in the development of technology that monitors brain-cell activity at a resolution never achieved before.

The Decadal Survey produced by the National Research Council has listed what it believes the big priorities should be in the coming 10 years for American astronomical and astrophysical research.

The Pentagon's got a new game plan to detect deadly chemical threats: tiny, iridescent sensors that are designed to mimic one of nature's most colorful creatures.

Scientists are working on a way to make fuel from thin air, which twists our noodles even more than last week's revelation that it's possible to power a car using human excrement.

Although some of the less stable people out there are predicting an Armageddon ending in 2010, scientists have said that's not going to happen. Instead, our great great great great great grandchildren can look forward to stars that heat up and radiate the earth or a meteorite hitting instead.

The Sun's surface erupted early Sunday morning, shooting a wall of ionized atoms directly at Earth, scientists say. It is expected to create a geomagnetic storm and a spectacular light show -- and it could pose a threat to satellites in orbit, as well.

Fifty years after physicists invented the laser, ushering in everything from supermarket scanners to music CDs, scientists have conceived its opposite — the “antilaser.”

Multiple alarms woke the space station's crew late Saturday after one of two coolant loops shut down, forcing the astronauts to power down critical systems. Two spacewalks are being planned to fix the problem.

Researchers have identified rocks that they say could contain the fossilised remains of life on early Mars. The team made their discovery in the ancient rocks of Nili Fossae.

A UN panel has added Florida's Everglades National Park and Madagascar's tropical rainforest to a list of world heritage sites at risk.

A large asteroid in space that has a remote chance of slamming into the Earth would be most likely hit in 2182, if it crashed into our planet at all, a new study suggests.

Chinese engineers are considering a new super-powerful engine for the next generation of space rockets, say officials.
