Until a recent discovery by a University of Montana research lab, it was thought that cicadas had a symbiotic relationship with two important bacteria that live within the cells of its body.
Corals that build reefs have few defenses against rising ocean temperatures and other effects of global climate change.
A team of researchers has captured images of green alga consuming bacteria, offering a glimpse at how early organisms dating back more than 1 billion years may have acquired free-living photosynthetic cells.
Microscopic animals held algae captive and stole their genes for energy production, thereby evolving into a new and more powerful species many millions of years ago reveals a new study published today in the journal Nature.
Two years ago, a 71-year-old Indiana man impaled his hand on a branch after cutting down a dead crab apple tree, causing an infection that led University of Utah scientists to discover a new bacterium and solve a mystery about how bacteria came to live inside insects.
A study published in this week's issue of Science shows how tiny single-celled algae and a high specialized bacteria have formed a partnership that helps keep the ocean fertilized. This symbiotic pair takes nitrogen from the atmosphere and "fixes" it into a form that other organisms can use.
A general rule of Darwinian evolution is that diversity provides for a more robust population that is capable of withstanding a higher degree of stress than a more homogenous population.
Researchers of the Max Planck Institute for Marine Microbiology along with Australian colleagues, have examined corals from the Great Barrier Reef affected by the Black Band Disease and identified the critical parameters that allow this prevalent disease to cause wide mortality of corals around the world.
The major difference between plant and animal cells is the photosynthetic process, which converts light energy into chemical energy.
Atmospheric oxygen really took off on our planet about 2.4 billion years ago during the Great Oxygenation Event.
Aphids or greenfly, plant lice (superfamily Aphidoidea) are small plant-feeding insects (1 to 10 mm). Of the 4,000 species of known aphids (distributed in 10 families), around 250 are serious pests for agriculture and forestry as well as an annoyance for gardeners. Natural predators include ladybirds, hoverfly larvae and lacewings. Aphids have two compound eyes and two ocular tubercles made up of 3 lenses, each of which is located behind and above the compound eyes. They have 2 tarsal...
