BERLIN, Germany (PNN) - August 30, 2016 - Scientists have found evidence to support what many dog owners have long believed: man’s best friend really does understand some of what we’re saying.

Researchers in Hungary scanned the brains of dogs as they were listening to their trainer speaking to determine which parts of the brain they were using.

They found that dogs processed words with the left hemisphere and used the right hemisphere to process pitch - just like people.

Astronomers have discovered evidence of a small, rocky planet orbiting our nearest star – and it may even be a bit like Earth. Nobody knows whether the planet, called Proxima b, could ever sustain life. The little planet orbits our sun’s nearest neighbouring star, Proxima Centauri, making it the closest exoplanet ever found.

SANTA BARBARA, Kalifornia (PNN) - August 26, 2016 - While a real-life Jurassic Park may not be opening any time soon, bringing back more recently extinct species, like the woolly mammoth or the dodo, is a distinct possibility. But while scientists in the movie "were so preoccupied with whether or not they could, they didn't stop to think if they should," real-world scientists are now considering the latter. With various “de-extinction” projects in the works right now, researchers at University of Kalifornia, Santa Barbara have published a paper analyzing the ecological benefits, risks and responsibilities of reintroducing once-extinct species into modern ecosystems.

CHICAGO, Illinois (PNN) - July 29, 2016 – Re-creating a plant's ability to use sunlight to turn carbon dioxide into fuel, something known as artificial photosynthesis, is one of the holy grails of green energy research. Researchers have now edged closer toward this dream technology, developing what they describe as a game-changing solar cell that produces hydrocarbon fuels in the lab, with potential applications ranging from large-scale uses on Earth to providing power on Mars.
