Elephants are among the most intelligent animals in the world. Previous studies have found that elephants are able to recognize individual faces and that they have a unique and sophisticated set of social norms which even includes mourning. Recently scientists have discovered that elephants have their own form of rudimentary language which seems primarily designed to warn other members of their herd about potential threats.

 

Researchers from a collaborative team comprising scientists from Oxford University, Save the Elephants and Disney’s Animal Kingdom have been studying the noises elephants make when exposed to certain threats. The researchers found that if elephants are exposed to the sound of a human voice, specifically speaking in the language of the Samburu tribe of northern Kenya, that elephants become vigilant and emit a distinctive noise that sounds like a low rumble. Other elephants, not exposed to the human voice, reacted to the elephant alarm by running away and making the exact same rumbling noise.

Machine learning advances go above and beyond what has presently been achieved in medicine, the findings showed. Machine learning is overtaking humans in predicting death and heart attack, suggesting a continued maturation of the technology and a potential for increased efficiency among caregivers in the healthcare system, finds a study presented at the International Conference on Nuclear Cardiology and Cardiac.

A team of British scientists and engineers have created a full scale model for a car they intend to drive more than 1,000 mph. 

The model, named the Bloodhound SuperSonic Car (SSC), was built by a team of aerodynamic experts, who took three years to build it. Recently shown off to the world at the Farnborough International Air Show, the 42-foot-long Bloodhound resembles a bright blue missile with wheels.

To the naked eye, our Galaxy appears as the Milky Way: an irregular, unevenly luminous band of dim light. Invisible from urban habitats and barely visible from many suburban locations, the Milky Way is actually bright enough, when located at the zenith of a dark sky site on a moonless night, to cast shadows on the ground. It will be useful to summarize briefly how our understanding has progressed from this naked eye view to the Galaxy model of modern astronomy.

The search for life on Mars shouldn’t focus exclusively on the distant past, some researchers say.

 

Four billion years ago, the Martian surface was apparently quite habitable, featuring rivers, lakes and even a deep ocean. Indeed, some astrobiologists view ancient Mars as an even better cradle for life than Earth was, and they suspect that life on our planet may have come here long ago aboard Mars rocks blasted into space by a powerful impact.
