ROME, Aug 10 (Reuters) – The U.N.’s food agency stepped up the pressure on the United States on Friday to change its biofuel policies because of the danger of a world food crisis, 南京夜网桑拿龙凤419
Ever wondered what it would look like to see a seven-ton Tyrannosaurus rex chomp down on his dinner (and hold the prey animal’s bloody head aloft for its young ones to see)? How about a 60-foot mega-shark, Carcharodon megalodon, pursuing its prey through the ocean?
Alas, there were no photographers around to record the gruesome events. Fortunately for us, there are some highly skilled paleoartists who can provide a realistic look at dinosaur predation–and fossils suggest the interactions between dinosaur predator and dinosaur prey could be pretty ferocious.
“With one possible exception, there can be no more dynamic interaction between two organisms than that of predator and prey,” Steve White, editor of Dinosaur Art: The World’s Greatest Paleoart, told The Huffington Post in an email. “And when you’re dealing with creatures as magnificent as T-rex or a sabre-toothed cat, it’s little wonder that paleoartists–those who specialise in illustrating these ancient creatures–often choose such dynamic subject matter.”

A study suggesting climate change deniers also tend to hold general beliefs in conspiracy theories has sparked accusations of a conspiracy on climate change-denial blogs.
The research, which will be published in an upcoming issue of the journal Psychological Science, surveyed more than 1,000 readers of science blogs regarding their beliefs regarding global warming. The results revealed that people who tend to believe in a wide array of conspiracy theories are more likely to reject the scientific consensus that the Earth is heating up.
University of Western Australia psychologist Stephan Lewandowsky based the findings on responses from an 南京夜网论坛

Imagine if the reefs of the world, once coated by colorful corals, suddenly became bare. What would it mean for humanity?
I reached out to Dr. Stuart Sandin of the Center for Marine Biodiversity and Conservation at UC San Diego’s Scripps Institution of Oceanography to learn more about coral reefs. These complex ecosystems are threatened by human activities like overfishing, pollution, and climate change.
In an interesting twist, we can learn a lot about the paleoclimate by studying corals. Ironically, the very organisms that can teach us about climate science are being threatened by climate change.
