Crop rotation boosts soil microbes, benefits plant growth
In the first study of its kind, new research shows that crop rotations, in isolation from other management factors, can increase the functions performed by soil microbial communities that benefit plant growth.

Evidence that Earth's first mass extinction was caused by critters not catastrophe
The Earth's first mass extinction event 540 million years ago was caused not by a meteorite impact or volcanic super-eruption but by the rise of early animals that dramatically changed the prehistoric environment.

How does your microbiome grow?
The reproduction rates of the bacteria in one's gut may be a good indicator of health or disease, scientists say. In their examination of human microbiome data, the research group found that particular changes in bacterial growth rates are uniquely associated with type II diabetes; others are tied to inflammatory bowel disease, for example.

Biodiversity belowground is just as important as aboveground
Although most of the world's biodiversity is below ground, surprisingly little is known about how it affects ecosystems or how it will be affected by climate change. A new study demonstrates that soil bacteria and the richness of animal species belowground play a key role in regulating a whole suite of ecosystem functions on Earth. The authors call for far more attention to this overlooked world of worms, bugs and bacteria in the soil.

Parasitized bees are self-medicating in the wild
Bumblebees infected with a common intestinal parasite are drawn to flowers whose nectar and pollen have a medicinal effect, a study shows. The findings suggest that plant chemistry could help combat the decline of bee species.

Yeast study yields insights into cell-division cycle
Studies using yeast genetics have provided new, fundamental insights into the cell-division cycle, researchers report. The findings show that an organelle known as the vacuole, which performs a variety of cellular housekeeping functions, plays an essential role in the initiation of the cell-division cycle.

Oxygen oasis in Antarctic lake reflects Earth in distant past
At the bottom of a frigid Antarctic lake, a thin layer of green slime is generating a little oasis of oxygen, a team of researchers has found. It's the first modern replica discovered of conditions on Earth two and a half billion years ago, before oxygen became common in the atmosphere.
