A new analysis shows that the Sun is more active now than it has been at anytime in the previous 1,000 years. Scientists based at the Institute for Astronomy in Zurich used ice cores from Greenland to construct a picture of our star's activity in the past. They say that over the last century the number of sunspots rose at the same time that the Earth's climate became steadily warmer. The warming is being amplified by gases from...

An Australian scientist says the continent needs five or six seasons to suit its climate. Tim Entwisle, chief of Sydney's Royal Botanic Gardens, says Australia should "unhook" itself from the "arbitrary" four seasons it inherited from Britain...

Super článok, resp. téma. Stále premýšľam - nebolo by úžasné, keby sa raz zistilo, že nejakí neandertálci prežili až do historických čias a sú to obri a lesní ľudia, ktorých poznáme z rozprávok a povestí? Ale vlastne už 24 tisíc rokov dozadu nie je tak veľa, že. Tomáš J. Fülöpp...

The researchers sequenced haemoglobin genes from the DNA of three Siberian mammoths, tens of thousands of years old, which were preserved in the permafrost. The mammoth DNA sequences were converted into RNA (a molecule similar to DNA which is central to the production of proteins) and inserted into E. coli bacteria. The bacteria faithfully manufactured the mammoth protein. The resulting haemoglobin molecules are no different than '...

Over the last 11,700 years - an epoch that geologists call the Holocene - climate has remained remarkably stable. This allowed humans to plan ahead, inventing agriculture, cities, communication networks and new forms of energy. Some geologists now believe that human activity has so irrevocably altered our planet that we have entered a new geological age.

A study of hailstones has found large numbers of bacteria at their cores. The find lends credence to the "bio-precipitation" idea, which suggests that bacteria are actively involved in stimulating precipitation. The bacteria have protein coatings that cause water to freeze at relatively warm temperatures...

Relatively mild drought conditions may have been enough to cause the collapse of the Classic Maya civilisation, which flourished until about AD950 in what is now southern Mexico and Guatemala.
