Scientists Offer New Way To Look At The Origins Of Life
2012-12-13 15:45:08

[Watch Video: Paul Davies on the Origins of Life] Brett Smith for redOrbit.com - Your Universe Online People have been trying to understand the origins of life on Earth through scientific means since the concept of science began and a pair of Arizona State University researchers suggests in a new report that we´ve been approaching the question incorrectly, almost from the beginning. In a paper titled, "The algorithmic origins of life,” Paul Davies and Sara Walker...

What Sparked The Origin Of Life
2012-11-27 06:45:21

April Flowers for redOrbit.com - Your Universe Online Scientists have questioned how life began on a molecular level for a very long time. And now, an international team of researchers has presented evidence that sheds light on a possible mechanism by which life may have gotten a foothold in the chemical soup that existed early in the Earth's history. Several competing theories have been previously proposed for how life got its start even before the first genes or living cells emerged....

Icy Particles Of Space May Have Been The Ingredients For Life On Earth

Lawrence LeBlond for redOrbit.com - Your Universe Online In an effort to better understand how life started on Earth, researchers at NASA´s Jet Propulsion Laboratory in Pasadena, California are cooking up icy concoctions of organisms (carbon-bearing molecules) then zapping them with lasers. The JPL crew´s experiments also provide the first direct look at the organic chemistry that takes place in the chilly regions of our solar system, and even chillier reaches between stars....

Is The Possibly Of New Life Forms Really So Alien?
2012-05-09 07:44:18

The idea of discovering a new form of life has not only excited astronomers and astrobiologists for decades, but also the wider public. The notion that we are the only example of a successful life form in the galaxy has, for many, seemed like an unlikely statistic, as we discover more and more habitable planetary bodies and hear yet more evidence of life's ability to survive in extreme conditions. A new essay, published May 8 in the online, open-access journal PLoS Biology, examines what...

Researchers Create Synthetic DNA/RNA That Can Evolve
2012-04-20 07:04:05

Researchers have created artificial genetic material known as Xenonucleic acids, or XNAs, that can store information and evolve over generations in a comparable way to DNA. The research, reported Friday in the journal Science, has implications for the fields of molecular medicine and biotechnology, and sheds new light on how molecules first replicated and assembled into life billions of years ago. Living systems owe their existence to the information-carrying molecules DNA and...

Complex organic compounds, including many important to life on Earth, were readily produced under conditions that likely prevailed in the primordial solar system. Scientists at the University of Chicago and NASA Ames Research Center came to this conclusion after linking computer simulations to laboratory experiments. Fred Ciesla, assistant professor in geophysical sciences at UChicago, simulated the dynamics of the solar nebula, the cloud of gas and dust from which the sun and the planets...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
