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)

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)

Evidence of 3.5 billion-year-old bacterial ecosystems found in Australia
Reconstructing the rise of life during the period of Earth's history when it first evolved is challenging. Earth's oldest sedimentary rocks are not only rare, but also almost always altered by hydrothermal and tectonic activity. View News Article (2013-11-13)

Astronomers: 'Tilt-a-worlds' could harbor life
A fluctuating tilt in a planet's orbit does not preclude the possibility of life, according to new research by astronomers at the University of Washington, Utah's Weber State University and NASA. In fact, sometimes it helps. View News Article (2014-04-16)

Silicon May Have Been The Key To Start Of Life On Earth
A scientist at the University of Sheffield has discovered that silicon may have been key to the establishment of life on earth. Until now it has generally been thought that bacteria do not interact with silicon, but Dr Milton Wainwright and his team at the University's Department of Molecular Biology and Biotechnology, has found that this is not the case. In a paper, due to be published in the... View News Article (2003-10-23)

Montana State chemists unravel secrets of unique enzyme
Montana State University chemists have determined the structure of an intermediate form of a unique enzyme that participates in some of the most fundamental reactions in biology. View News Article (2010-04-26)
