We tend to think of such events as occasional, inconvenient blips. But in fact they are becoming increasingly common, and will only get more frequent and severe. This is because our electricity systems are more fragile than is commonly supposed, and are getting frailer. Unless we act, blackouts will become a regular, extremely disruptive part of everyday life.

The vulnerability of such systems is demonstrated by the Italian blackout of 2003. The event began when a falling tree broke a power line in Switzerland; when a second tree took out another Swiss power line, connectors towards Italy tripped and several Italian power plants failed as a result. Virtually the whole country was left without power. It says something when a nation can be brought to a halt by two trees falling outside its borders.

We predict that blackouts will occur with greater frequency and greater severity due to trends in both electricity supply and demand. Supply will become increasingly precarious because of the depletion of fossil fuels, neglected infrastructure and the shift toward less reliable renewable energy. Demand, meanwhile, will grow because of rising populations and affluence.

Feathered dinosaur death site is an "animal Pompeii" | Ars Technica - 0 views

The fossils of the Jehol Biota are from the Early Cretaceous period, about 130 million years ago, and they comprise a wide variety of animals and plants. So far, about 60 species of plants, 1,000 species of invertebrates, and 140 species of vertebrates have been found in the Jehol Biota.

One of the most remarkable discoveries to arise from these fossils came in 2010, when Michael Benton of the University of Bristol found color-banding preserved in dinosaur fossils. These stripes of light and dark are similar to stripes in modern birds, and they provided further evidence that dinosaurs evolved into birds. Benton also found that these fossils had intact mealnosomes—organelles that make pigments. This discovery allowed paleontologists to tell the colors of dinosaurs' feathers for the first time.
'The Walking Dead' Star Norman Reedus Talks About Daryl Dixon's Relationship With Beth Greene - International Business Times - 0 views

"At the end of a dark tunnel, she was the flicker of light when Daryl didn't think there was any light at that time anywhere. She gave him a little hope that there's something good left. But I think if he had any sort of romantic notions toward Beth, he didn't know what it meant. Just to have the little butterfly feeling for a second is something. It might have been like one tiny moth, but it was a flutter, and that was good enough for him," Reedus said.
