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)


A warmer planetary haven around cool stars, as ice warms rather than cools
In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star's light with ice and snow on the planet's surface. View News Article (2013-07-19)


Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen. View News Article (2006-08-24)


From toxicity to life: arsenic proves to be a building block
Arsenic -- an element that triggers death for most Earthly life forms -- is actually allowing for bacterium to thrive and reproduce.  View News Article (2010-12-03)


Model gives clearer idea of how oxygen came to dominate Earth's atmosphere
A number of hypotheses have been used to explain how free oxygen first accumulated in Earth's atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. View News Article (2005-08-09)


Dust-enshrouded star looks similar to our sun
Astronomers report tremendous quantities of warm dusty debris surrounding a star with luminosity and mass similar to the sun's, but located 300 light-years from Earth. View News Article (2005-07-21)
