Builders of hydroelectric dams are required to perform seismic hazard studies before their designs are approved.
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.
The study was based on observations that the more successful crops in areas typically affected by drought are usually protected by a thicker layer of leaf wax than other plants.
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.
Decades of research has shown that apes, in spite of their proverbial aping abilities, are rather poor imitators, especially when compared to human children. Current theories hold that apes are worse imitators because they lack this social and communicative side of imitation. A new study from Lund University, published in the journal Primates, has instead targeted the interactive side of imitation directly, and finds that the divide between humans and chimpanzees is less clear cut.
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.
