Mystery radio signals coming from a sun-like star baffle scientists.
LONDON, England (PNN) - August 29, 2016 - A spike in radio signals coming from the direction of a sun-like star has excited astronomers.
The signals seem to be originating from a star known as HD 164595 in the constellation Hercules, around 95 light years away.
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.
SYDNEY, Australia (PNN) - August 2, 2016 - It's a question that has baffled humans long before The Matrix; do we exist and what if we are living in a simulation?
While we have yet to have a definitive answer, one expert has waded through this philosophical quagmire to explain arguments about whether we are just a brain in a vat.
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.
A Swedish entrepreneur inventor has deceloped a gasoline-powered flying carpet that actually works! Amazing!
Composite metal foams are tough stuff. Tough enough to turn an armor-piercing bullet into dust on impact. Given that these foams are also lighter than metal plate, the material has obvious implications for creating new types of body and vehicle armor - and that’s just the beginning of its potential uses. Afsaneh Rabiei, a professor of mechanical and aerospace engineering at North Carolina State, has spent years developing composite metal foams and investigating their unusual properties.
NEW YORK (PNN) - July 26, 2016 - We already interact with artificial intelligence in our daily lives. Furby and Clippy were early forms; driverless cars and Facebook's chatbots pick up the mantle today. But if AI is to continue its evolution, it will have to get more convincingly human. Right now, its capacity for emotional depth is seriously lacking.
STOCKHOLM, Sweden (PNN) - July 25, 2016 - Eight petrol-powered heavy-duty propellers, one tube lattice frame, a simple seat, and a hobby-grade R/C controller wired in. What could possibly go wrong? This Swedish engineer displays a pair of colossal cojones as he puts his homemade flying carpet multirotor to the test.
RALEIGH, North Carolina (PNN) - April 10, 2016 - Composite metal foams are little-known materials that are beginning to show some big promise. Last year we saw researchers adapt these lightweight materials to stop various forms of radiation in their tracks, and now the same team has ramped things up to offer protection from something with a bit more force: an armor-piercing bullet, which was turned to dust on impact.
Some are potentially habitable.
HOUSTON, Texas (PNN) - July 19, 2016 - NASA announced today that its Kepler spacecraft has discovered a "crop of more than 100 planets" orbiting the M dwarf star K2-72, 181 light years away from Earth.
