In an upcoming paper for the journal Aquatic Mammals, a pair of scientists detail a series of interactions between an adult bottlenose dolphin with scoliosis and a group of sperm whales in the Azores. The scientists describe their research as the first time sperm whales have been observed interacting in a non-aggressive way with a…
Our first foray into laser-equipped combat aircraft was the Airborne Laser Testbed, a Boeing 747 with a gigantic chemically-pumped megawatt laser turret in its nose. It was pretty awesome from a conceptual standpoint, but it didn’t work very well, and was scrapped last year. This doesn’t mean that the idea of high-powered lasers on aircraft…
Birds and humans use stars to navigate, but can insects map their routes? For dung beetles, a new study says the answer is yes. The African insects appear to find their way via the Milky Way. It’s the first evidence that any insect can orientate themselves with the sky, and the first evidence that any…
Praying, fighting, dancing, chanting — human rituals could illuminate the growth of community and the origins of civilization.
A feathered dinosaur fossil about 12 inches long is older than bird-like dinosaurs from which birds are thought to have evolved, British paleontologists say. The discovery of the new bird-like dinosaur from the Jurassic period, dubbed Eosinopteryx, presents a challenge to widely accepted theories on the origin of flight, they said. The fossilized remains found…
The robot equipment industry has one word for the alarmist articles and television news programs that predict a robot is about to steal your job: Fiddlesticks! Well, that wasn’t actually the word used at the Automate 2013 trade show held recently in Chicago, but the sentiment was the same. During one presentation, Henrik I. Christensen,…
The stuff we’re made of may be the means by which we store information that we want kept around long after we’re gone. Scientists have developed a technique of storing information in DNA, the molecule found in living creatures including humans that contains genetic instructions. The experiment is discussed in a new study in the…
You know that dog biscuit shaped like a bone but made mostly of wheat? The fact that your dog is satisfied with it instead of going for a piece of your thigh may be one of the big reasons why its ancestors evolved from wolves to house pets. A team of Swedish researchers has compared…
Since 1799, the Royal Institution of Great Britain has occupied a grand building in London’s Mayfair, surrounded today by luxury shops and private art galleries. For many years, the building was a central part of British science. Michael Faraday dazzled crowds there in the nineteenth century with pyrotechnic displays of chemistry. In many respects, its…
Researchers have been able to trace a line between some of the earliest modern humans to settle in China and people living in the region today. The evidence comes from DNA extracted from a 40,000-year-old leg bone found in a cave near Beijing. Results show that the person it belonged to was related to the…
