Volcanic rock discovery could reveal secrets of Earth's history Geologists in Scotland have discovered a completely new type of volcanic rock, which they believe will help to pinpoint the precise time in Earth's history at which life emerged from the oceans and began to colonise...

A scientist believes techniques used to find oil and gas in the North Sea could help establish whether life could survive on Mars. Professor John Parnell, from Aberdeen University, has been studying the Haughton meteor crater using methods for detecting oil and gas underground. He was part of...

The chances of finding life somewhere else in the Universe depends on how many planets are capable of supporting life. According to new calculations by astronomers at Open University, as many as half of all star systems cou...

NASA's Spitzer Space Telescope has found the ingredients for life all the way back to a time when the universe was a mere youngster. Using Spitzer, scientists have detected organic molecules in galaxies when our universe was one-fourth of its current age of about 14 billion years. These large mol...

Some hardy Earth microbes could survive long enough on Mars to complicate the search for alien life, according to a new study co-authored by University of Florida researchers. Though scientists looking for life on Mars worry about contamination from stowaway spores clinging to spacecraft, th...

Half-a-billion years ago, as an explosion of life was starting to produce diverse new forms, the Antrim Plateau Volcanics of northern Australia began spewing massive amounts of lava. Before it was over, lava floods had buried almost a fifth of Australia's area today. The newly identified K...

Cave extremeophiles (microbes that live in very difficult environments) have been the object of Hazel Bartons research for a long time. Barton, a professor of microbiology at Northern Kentucky University has visited more than 1000 caves in the United States, Britain, Greenland, Mexico, Belize...

Tough Enough for Mars, but Deinococcus is from Earth Results of a recent study titled Deinococcus geothermalis: The Pool of Extreme Radiation Resistance Genes Shrinks, will be published in the Sept. 26 edition of PLoS ONE. Bacteria of the genus Deinococcus are extremely resistant to ionising ra...

Life on Venus could be blown to Earth by powerful winds, scientists claim. Previous research has considered the possibility of micro organisms existing in Venus's atmosphere despite extreme temperatures on its surface. But two scientists at the Cardiff Centre for Astrobiology say microbes fro...

A classic experiment proving amino acids are created when inorganic molecules are exposed to electricity isn't the whole story, it turns out. The 1953 Miller-Urey Synthesis had two sibling studies, neither of which was published. Vials containing the products from those experiments were recen...

Small stretches of seemingly useless DNA harbour a big secret, say researchers at the Stanford University School of Medicine. There's one problem: We don't know what it is. Although individual laboratory animals appear to live happily when these genetic ciphers are deleted, these snippets have...

Astrobiologists have often pondered "life as we do not know it" in the context of extraterrestrial life, says Paul Davies, an internationally acclaimed theoretical physicist and cosmologist at Arizona State University. "But," he asks, "has there been a blind spot t...

Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things w...

Inventories of living and dead organisms could serve as a relatively fast, simple and inexpensive preliminary means of assessing human impact on ecosystems. The University of Chicagos Susan Kidwell explains how measuring the degree of live-dead mismatch could be used as an ecological tool in th...

A prehistoric giraffe discovered in eastern Macedonia earlier this summer is the first to be found in Europe, according to palaeontologists. The ancient animal was among several sets of fossil remains dating five to ten million years ago. Located outside the village of Stamer, near Delcovo, the f...

Half of Earth's life may lie below While astronomers scour the skies for signs of life in outer space, biologists are exploring an enormous living world buried below the surface of the Earth. Scientists estimate that nearly half the living material on our planet is hidden in or beneath the ocean or in...
