Life Found Deep Under Antarctic Ice for First Time?
The newfound life-forms have little connection to life on the earth’s surface and many apparently survive by “eating rocks,” team member Brent Christner said in an interview from the U.S. McMurdo Station, after spending several weeks working at a remote field site at Lake Whillans.
That may explain how life on other celestial objects—such as on the moons of Jupiter and Saturn—survive in the absence of available carbon.
“The conditions faced by organisms in Lake Whillans are quite parallel to what we think it would be like on those icy moons,” Christner said.
“What we found tells us a lot about extreme life on Earth,” and how similar life beyond Earth might survive.
Dogs Understand Human Perspective: Study : animals : NatureWorldNews
A recent study reveals that dogs are much likely to steal food in the dark when humans cannot notice them, indicating they understand a human's perspective.
What Are Dogs Saying When They Bark? | Scientific American
However, more recent research indicates that there might be more to barking than we first thought. Dogs have fairly plastic vocal cords, or a “modifiable vocal tract.” Dogs might be able to subtly alter their voices to produce a wide variety of different sounds that could have different meanings. Dogs might even be altering their voices in ways that are clear to other dogs but not to humans. When scientists have taken spectrograms, or pictures, of dog barks, it turns out that not all barks are the same—even from the same dog. Depending on the context, a dog’s barks can vary in timing, pitch, and amplitude. Perhaps they have different meanings.
