Bacteria use 'sophisticated language' to communicate

Common bacteria found in water and soil talk to each other using language in much the same way as we do, scientists have discovered.

The bugs display a level of "combinatorial" communication previously thought to be unique to humans and certain other primates, which involves using two signals together to transmit a message that is distinct from them both.

Until now this type of communication had only been observed in humans and their closest relatives. However, the study published in the Public Library Of Science ONE found that the Psuedomonas aeruginosa microbe is similarly capable using chemicals instead of words.

Kepler-186f planet 'could support life'

An Earth-like planet confirmed by Nasa in the habitable zone around the Kelper-186 star has 'potential' to host liquid water - one of the pre-requisites for life as we know it to exist.

Scientists scouring the sky have discovered an 'Earth-like' planet in the habitable zone.

The new planet, dubbed Kepler-186f, was discovered using NASA's Kepler telescope, which was launched in March 2009 to search for Earth-sized planets in our corner of the Milky Way Galaxy.

A habitable zone planet orbits its star at a distance where any water on the planet's surface is likely to stay liquid. Since liquid water is critical to life on Earth, many astronomers believe the search for extraterrestrial life should focus on planets where liquid water occurs.

"Some people call these habitable planets, which of course we have no idea if they are," astronomer Stephen Kane said. "We simply know that they are in the habitable zone, and that is the best place to start looking for habitable planets."
