Predatory dinos were truly big-mouths.  Science News for Students

Many dinosaurs are known for their fearsome teeth. Allosaurus had sharp, bladelike choppers. Many were 5 to 10 centimeters (2 to 4 inches) long. Tyrannosaurus rex had bigger ones — the size of bananas. Big teeth are a plus for a predator. But unless a creature can open its mouth very wide, long teeth might actually be a good recipe for starvation. Many big-toothed species survived for millions of years, though. And that is because their jaws could open plenty wide, the better to latch on to big prey, a new study finds. Read more…

Canadians back bold climate-change action, poll finds. Globe and Mail

Prime Minister Justin Trudeau heads to global climate talks in Paris with a new pledge of billions for the cause and a call for a strong international agreement, promising to follow up with a domestic plan with the provinces – and a new poll suggests that is probably in line with what Canadians want.

At the Commonwealth summit in Malta on Thursday, Mr. Trudeau grabbed a little attention by announcing that Canada will put $2.65-billion over five years into climate-change funds for developing countries – a doubling of previous funding. He announced it behind closed doors to fellow leaders with some flourish, according to aides: “I’m here today not just to say Canada’s back but to show it,” they quoted him as sayingRead more…
