It happens to all of us: we suddenly and inexplicably feel cheery or blue, even though our mood was quite different just moments before. Often the culprit is a subliminal cue, or, as psychologists call it, priming. But we do not have to be at the mercy of these unconscious cues.

When you think of old age – of people over the age of 65 years – what immediately comes to mind?

NASA's orbiting Kepler telescope has discovered its first planet in the habitable zone of another star. By "habitable," astronomers mean that a planet could harbor temperatures conducive to liquid water--and maybe life. [More]

Chimpanzees meld sounds and colours, associating light objects with high tones and dark objects with deeper tones. [More]

DURBAN, South Africa--My share of the carbon dioxide my flight to Johannesburg emitted over 15 hours amounted to 1,391.3 kilograms, according to the helpful information provided by South African Airlines. Add a dollop of 53.8 kilograms of CO2 for the jet jaunt to Durban and you can see that the aviation industry--and the Durban climate talks --have an emissions problem.

As a biological feat, it was the equivalent of an 80-year-old woman giving birth: Because of a mutation, Coleen Murphy's worms were still fertile and laying eggs right up until the end of their lives. The worms' impressive performance adds weight to the evidence that the biological clock that rules reproduction is separate from the one that grants us the traditional threescore and 10. [More]

In the world of science, it s publish or perish. Researchers who publish a greater number of papers in high-status journals are more likely then their colleagues to win tenure positions, research grants, and prestigious reputations. The competition is fierce enough to compel some scientists to cheat.

Comparison of "habitable zone" of Kepler 22 system and our solar system (NASA/Kepler) Today sees the announcement that one of the “candidate” planets listed from NASA’s Kepler mission back in February is now confirmed, and it’s a key one. At 2.4 times the diameter of the Earth the planet Kepler 22-b also orbits its parent star (which is a slightly less massive G-dwarf star than the Sun and 25% less luminous) in 290 Earth-days, which places it within the nominal “ habitable zone “. This system is about 600 light years from us.
