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)

Odd Tilts Could Make More Worlds Habitable
Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according to new modeling by NASA and university scientists affiliated with the NASA Astrobiology Institute. View News Article (2014-04-16)

Bacteria Get New Badge as Planet's Detoxifier
A study published this week in PLOS ONE authored by Dr. Henry Sun and his postdoctoral student Dr. Gaosen Zhang of Nevada based research institute DRI provides new evidence that Earth bacteria can do something that is quite unusual. Despite the fact that these bacteria are made of left-handed (L) amino acids, they are able to grow on right-handed (D) amino acids. View News Article (2014-04-04)

Robotic arm probes chemistry of 3-D objects by mass spectrometry
When life on Earth was first getting started, simple molecules bonded together into the precursors of modern genetic material. View News Article (2014-03-26)

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)

Scientists reveal why life got big in the Earth's early oceans
Why did life forms first begin to get larger and what advantage did this increase in size provide? UCLA biologists working with an international team of scientists examined the earliest communities of large multicellular organisms in the fossil record to help answer this question.  View News Article (2014-01-27)

Astronomers solve temperature mystery of planetary atmospheres
An atmospheric peculiarity the Earth shares with Jupiter, Saturn, Uranus and Neptune is likely common to billions of planets, University of Washington astronomers have found, and knowing that may help in the search for potentially habitable worlds. View News Article (2013-12-11)

Ancient minerals: Which gave rise to life?
Life originated as a result of natural processes that exploited early Earth's raw materials. Scientific models of life's origins almost always look to minerals for such essential tasks as the synthesis of life's molecular building blocks or the supply of metabolic energy. View News Article (2013-11-26)

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)

Rensselaer Researchers Propose New Theory To Explain Seeds of Life in Asteroids
A new look at the early solar system introduces an alternative to a long-taught, but largely discredited, theory that seeks to explain how biomolecules were once able to form inside of asteroids. View News Article (2013-10-02)
