Manipulating RNA can allow plants to yield dramatically more crops, as well as increasing drought tolerance, announced a group of scientists from the University of Chicago, Peking University and Guizhou University.
Drought can have a lasting impact on the community of microbes that live in and around roots of rice plants, a team led by UC Davis researchers has found. Root-associated microbes help plants take up nutrients from the soil, so the finding could help in understanding how rice responds to dry spe ...
Palaeontologist Tim Ewin is standing in a quarry, recalling the calamity that's written in the rocks under his mud-caked boots. "They tried to protect themselves, adopting the stress position of pulling their arms in," he continues. "But it was all in vain; you can see where their arms got snagg ...
Whether summer or winter, midnight sun or polar night—the sand on the ocean floor is always inhabited by the same bacteria. Although the microbial communities differ between different ocean regions, they do not change between the seasons. Presumably, there is simply no room for change. Researche ...
Blue whales, the largest animals ever to live, are surprisingly elusive. They're bigger than the biggest dinosaur ever was, capable of growing over 30 meters long and can weigh over 100 tons—almost as long as a 737 plane and as heavy as 40 elephants. They also have one of the loudest voices, and ...
A finger-sized fossil from 308 million years ago unearthed in the United States gives tantalizing clues to the habits of tiny dinosaur-like creatures that may be the forerunners of reptiles, researchers revealed Wednesday.
Results from a study published in Ibis show that how close Golden Eagles will fly to wind turbines depends on habitat suitability inside and outside of a wind farm. Also, the largest impact of wind farms was a loss of Golden Eagle habitat, which could be mitigated by including the study's findin ...
The Xerces blue butterfly was last seen flapping its iridescent periwinkle wings in San Francisco in the early 1940s. It's generally accepted to be extinct, the first American insect species destroyed by urban development, but there are lingering questions about whether it was really a species t ...
The finding comes out of an effort to map where vegetation is emitting and soaking up carbon dioxide from the atmosphere.Earth's trees and plants pull vast amounts of carbon dioxide out of the atmosphere during photosynthesis, incorporating some of that carbon into structures like wood.
The remains of microscopic plankton blooms in near-shore ocean environments slowly sink to the seafloor, setting off processes that forever alter an important record of Earth's history, according to research from geoscientists, including David Fike at Washington University in St. Louis.
As the world warms, sweeping changes in marine nutrients seem like an expected consequence of increased ocean temperatures. However, the reality is more complicated. New research suggests that processes below the ocean surface may be controlling what is happening above.
An adhesive tape patented by Staffordshire University researchers to recover trace evidence from crimes scenes is being adopted to analyze microplastics more efficiently. Man-made polymer particles or 'microplastics' are proven to be present in land, air and water environments. However, despite ...
It's hard to save what you can't identify. That's been a problem for the endangered salt marsh harvest mouse, which is found only in the salty, brackish waters of the San Francisco Bay area. The mouse competes for space with about eight million humans, and more than three-quarters of its habitat ...
