A new discovery of microbial activity in 3.5 billion-year-old volcanic rock and one of earths earliest signs of geological existence sheds new light on the antiquity of life, says University of Alberta researchers who are part of a team that made the groundbreaking finding.
"People have been looking for signs of early bacteria for the last 50 years," said Dr. Karlis Muehlenbachs, from the U of As Faculty of Science and an author on the paper just published in the journal Science. "A variety have claimed theyve seen it and subsequently been challenged as being flawed. We are suggesting that we have clear evidence of life prospering in an environment where no one else has bothered to look."
The research team, also made up of Drs. Harald Furnes from the University of Bergen in Norway, Neil Banerjee from the U of A, Hubert Staudigel from the University of California and Maarten de Wit from the University of Cape Town, studied samples of pillow lava taken from the Mesoarchean Barberton Greenstone Belt in South Africa. They found mineralized tubes that were formed in the pillow lava, suggesting microbes colonized basaltic glass of the early oceanic crust, much in the same way as they do modern volcanic glass.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
