Using the most precise seafloor maps ever created of Antarctica's Ross Sea, Rice University researchers have discovered a long-dead river system that once flowed beneath Antarctica's ice and influenced how ice streams melted after Earth's last ice age. The research appears online this week in Nature Geoscience.
In The Plant Cell, UMass Amherst molecular biologist Elizabeth Vierling reports that heat-stressed plants not only need to produce new proteins to survive the stress, they need to make them right away. 'We found that a delay of even six hours of new protein translation will inhibit optimal growth and reproduction. The plants might not outright die, but they are severely impaired without the rapid synthesis of these new proteins.'
NOAA's GOES-East satellite has been watching the remnants for former Tropical Storm Harvey as it tracks west across the Caribbean Sea. Early on Aug. 21 the remnants were just off the coast of eastern Honduras.
Former Tropical Depression 13E has strengthened into a Major Hurricane on the Saffir-Simpson Hurricane Wind Scale. NASA's Terra satellite passed over Kenneth and captured an image that showed a well-developed storm with a visible eye.
Researchers at the University of York working on a 700-year-old abandoned agricultural site in Tanzania have shown that soil erosion benefited farming practices for some 500 years.
More targeted efforts are needed from both the public and private insurance sectors in order to encourage people to take action to reduce their risk of flood damage, according to a new study of three European countries.
By 2100 some Southern Hemisphere whale species will not have reached half their pre-whaling numbers, while other species are expected to recover by 2050.
Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change.
Human interference in the deep sea could already be outpacing our basic understanding of how it functions. As a result, without increased research and an immediate review of deep ocean conservation measures, the creatures that live there face an uncertain future, Oxford University scientists have warned.
Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that marked the end of the age of dinosaurs.
