Arctic bacteria help in the search to find life on moon Europa
In a fjord in Canada scientists have found a landscape similar to one of Jupiter's icy moons: Europa. View News Article (2012-05-31)

Nickel isotope may be methane producing microbe biomarker
Nickel, an important trace nutrient for the single cell organisms that produce methane, may be a useful isotopic marker to pinpoint the past origins of these methanogenic microbes, according to Penn State and University of Bristol, UK, researchers. View News Article (2009-06-23)

The minerals on Mars influence the measuring of its temperature
A team of researchers from the CSIC-INTA Astrobiology Centre in Madrid has confirmed that the type of mineralogical composition on the surface of Mars influences the measuring of its temperature. View News Article (2009-07-14)

New Technique Could Be Used to Search Space Dust for Life's Ingredients
While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life. Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules that are critical for life. View News Article (2014-02-04)

Bacteria manipulate salt to build shelters to hibernate
For the first time, Spanish researchers have detected an unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water and is left to dry, bacteria manipulate the sodium chloride crystallisation to create biomineralogical biosaline 3D morphologically complex formations, where they hibernate.  View News Article (2014-07-25)

New research identifies diverse sources of methane in shallow Arctic lakes
New research into the changing ecology of thousands of shallow lakes on the North Slope of Alaska suggests that in scenarios of increasing global temperatures, methane-generating microbes, found in thawing lake sediments, may ramp up production of the potent greenhouse gas - which has a global warming potential 25 times greater than carbon dioxide. View News Article (2015-03-30)

Conceptualizing cancer cells as ancient 'toolkit'
Despite decades of research and billions of dollars, cancer remains a major killer, with an uncanny ability to evade both the body's defenses and medical intervention. Now an Arizona State University scientist believes he has an explanation. View News Article (2011-02-08)

Does life exist on other planets?
Recent research argues that an atmosphere rich in oxygen is the most likely source of energy for complex life to exist anywhere in the Universe, thereby limiting the number of places life may exist. View News Article (2005-06-20)

Cracking how life arose on earth may help clarify where else it might exist
Does life exist elsewhere or is our planet unique, making us truly alone in the universe? View News Article (2013-07-31)

Vitamin B3 Might Have Been Made in Space, Delivered to Earth by Meteorites
Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers.  View News Article (2014-04-18)
