Cataloguing Invisible Life: Microbe Genome Emerges From Lake Sediment

A University of Washington-led team has taken a sample of Lake Washington mud and successfully sequenced a complete genome for an unknown microorganism. Their method provides a way to discover new microscopic life in complex communities. Full story

Cataloguing Invisible Life: Microbe Genome Emerges from Lake Sediment

When entrepreneurial geneticist Craig Venter sailed around the world on his yacht sequencing samples of seawater, it was an ambitious project to use genetics to understand invisible ecological communities.

Cataloguing Invisible Life: Microbe Genome Emerges From Lake Sediment

When entrepreneurial geneticist Craig Venter sailed around the world on his yacht sequencing samples of seawater, it was an ambitious project to use genetics to understand invisible ecological communities. But his scientific legacy was disappointing – a jumble of mystery DNA fragments belonging to thousands of unknown organisms.

Cataloguing invisible life: Microbe genome emerges from lake sediment

The Lake Washington mud samples were mixed with food labeled with a heavy isotope of carbon, allowing researchers to look at DNA only from organisms that ate the labeled food.

Dispelling Myths About Geomagnetic Reversal

UniverseToday has an interesting look at geomagnetic reversal, the process in which the Earth's magnetic poles trade places. The article cites known trends and recent studies to debunk doomsday myths and unsubstantiated claims about the process. One such study is attempting to model the earth's core with a 26-ton ball of molten metal. Another recently found evidence that the Earth has a second, weaker magnetic field. "We do know that this magnetic pole flip-flop has occurred many times in the last few million years; the last occurred 780,000 years ago according to ferromagnetic sediment. A few scaremongering articles have said geomagnetic reversal occurs with 'clockwork regularity' — this is simply not true."
