Small, self-controlled planes combine plant pathology and engineering

...r been cultured before. Some of these microbes may thrive only in the atmosphere, and many of them may be new to science.” This and other fascinating results have led Schmale to hypothesize that some airborne microorganisms have “novel biochemical processes for interacting with each other as a community ...

In nature, proteins sweep up nanoparticles

...fide is a metabolic waste product of bacteria that thrive in the oxygen-free mine. Once the sulfide is released into the watery environment, it readily combines with metals, in this case zinc, to form nano-sized biominerals that measure about one-billionth of a meter in diameter. The team examined the bi...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...loyed to ‘engineer?an extremely small eukaryote to thrive in nature—which may well find applications in bioengineering," said Palenik. "It was particularly interesting to see the predicted use of selenium-containing enzymes as one of the tricks to maintain such tiny cells. There are many mechanisms that ca...

Amphibians in losing race with environmental change

...ods with very different climates, and continued to thrive while many other species went extinct. But right now, they just can't keep up." It has been estimated that the rate of plant and animal extinction is greater now than any known in the last 100,000 years, the researchers note in their report. Amphi...

Alien plants attack using 'resource conservation' as weapon, researchers say

...ative species and reducing biodiversity. Invaders thrive best in regions where there is an abundance of materials for growth, such as water, nutrients and light. Biologists have long assumed that alien species pose less of a threat in resource-poor environments because they are less able to compete with in...

UBC researchers reveal dwarf aquatic plants' hidden ancestry

... Native to Australia, New Zealand and India, they thrive in seasonal freshwater pools and swamps, and may blossom underwater at depths of up to one metre, or as the pools dry out. "For more than a century, scientists have been piecing together the details of the rapid rise and early diversification of f...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

...xtreme conditions. Indeed, many species of archaea thrive in environments that would kill other organisms, from Yellowstone hot springs to the hyper-salty Dead Sea to streams polluted by mining waste where the pH level is equivalent to battery acid. Archaea even inhabit the warm, dark environs of our intest...

Fire ants: Their true story told by the scientist who loves them

...cal havoc created by disturbed habitats ?fire ants thrive in them, natives don't. Consequently, the USDA has wasted millions on what Tschinkel calls politically motivated campaigns to eradicate S. invicta with little or no improvement in native survival to show for it. "Fire ants have been the victims of a...

Researchers appeal for new regulations to save coral reefs from live fish trade

...coral-eating crown-of-thorns starfish is likely to thrive in these situations, particularly when the corals are already stressed by a multitude of other impacts including global warming. According to the 2004 Status of the Coral Reefs of the World report, coral reefs are in serious decline due largely to ...

The metabolic protein required to thrive at high-temperature could only be made in one genetic region of the bacteria's DNA, meaning the researchers had only to characterize that small region of the genome for each new strain in order to measure evolutionary progress. The researchers sampl...
