Costs rise faster than water, according to sea level rise study'The complexity of climate change, adaptation, and flood damage can be disentangled by surprisingly simple mathematical functions,' said the lead author of a new study from the Potsdam Institute of Climate Impact Research.
Dusty dinosaur bone sheds new light on perplexing giant predatorsA PhD student who stumbled across a forgotten dinosaur bone in a museum drawer has gleaned insight not only into the enigmatic Abelisaur, but also into a paleontological conundrum: Stromer's Riddle.
Why do people trust robot rescuers more than humans?As machines become more autonomous, scientists are trying to figure out how humans interact with them, and why, in some cases, they trust machines blindly, in spite of common sense.
Owl wars: Biologists kill one bird to save anotherWith the cooperation of the US Fish and Wildlife Service, two biologists have been systematically shooting barred owls in their forest homes in the Pacific Northwest, hoping the casualty-heavy experiment will reveal a path to saving the Northern Spotted Owl.
First LookUnderstanding others: A smarter way to search for aliens?The best way to discover extraterrestrial life might be to consider that they could already be looking for us, scientists say.

After two technical delays, will SpaceX be able to launch Falcon 9 Sunday?A new rocket fuel feature appears to be causing technical problems. But even if the glitch is fixed for Sunday's launch, the big question still remains: Will the Falcon 9 be able to land back on Earth in one piece?
How an MIT team created a warning system for rogue wavesNew research improves the ability to forecast rogue waves, also known as killer waves, which can rise without warning to tower over ships and rigs, with potentially catastrophic results.
3.5 billion years ago, the Earth's climate maybe wasn't so different from todayA new study that looks at glacial deposits and hydrothermal fields at the bottom of the ocean disputes the conventional belief that Earth, in its earliest years, had scorching temperatures.
First LookWhat prehistoric wisdom teeth tell us about human evolutionPaleontologists have long wondered why human wisdom teeth are so much smaller than those found in fossils of homonin species. A team of evolutionary biologists say they have solved the mystery.
First LookDid global warming 'pause'? Depends how you define 'pause'The theory that global warming paused in the 2000s was largely put to rest last year when NOAA recalculated some of its data. However, a commentary published this month has called that recalculation into question.
First LookDid all animal life on Earth begin with a sea sponge?Genetic analysis of 640-million-year-old rocks suggests that the sea sponge may have been the first animal to develop on Earth.
