If you have ever seen, or spent time with (or, God forbid, had to live with) a colicky baby, this will make perfect sense to you. It may not make actual sense, but when the baby is crying you don't think very straight.

There once was a place on Earth so overrun with giant, meat-eating predators that even a Tyrannosaurus rex would have been nervous. One predator there was even bigger than T. rex, and scientists now say it's apparently the only aquatic dinosaur ever found.
The swimming monster is called Spinosaurus aegyptiacus. It was 50 feet long â€” longer than a school bus, and 9 feet longer than the biggest T. rex.

Two volcanoes half a world apart are causing havoc today: Several flights have been diverted around an eruption in Papua New Guinea, and authorities in Iceland briefly put aviation on highest alert (again) owing to a temperamental Mount Bardarbunga, which has been rumbling for the past week.
Scientists examining an unusual African fish that can walk and breathe air think they've learned a thing or two about how our distant ancestors made the leap from the oceans to terra firma some 400 million years ago.

Air pollution is clogging the skies of our planet. Now one scientist thinks Earth may be just one of many polluted worlds â€” and that searching for extraterrestrial smog may actually be a good way to search for alien intelligence.
"People refer to 'little green men,' but ETs that are detected by this method should not be labeled as green," says Avi Loeb, an astronomer at Harvard University.
The idea of finding alien polluters may be a bit of a long shot, but Loeb says it's possible.
