Washington, Dec 2 : The study of a rare mineral, which can be used to track ancient climates, will help scientists estimate what will be the condition of the world over the next century or two, as global warming begins to crank up the heat.

Binghamton University geologist Tim Lowenstein is doing the study.

Lowenstein and his colleague Robert Demicco at Binghamton University have discovered that nahcolite, a rare, yellowish-green or brown carbonate mineral, only forms on earth under environmental conditions marked by very high atmospheric CO2 levels.

That establishes it as both a marker and a benchmark that can be used by scientists as they consider the likely climatic implications of ever-increasing CO2 levels in our atmosphere today.

Washington, Dec 2 : A new study has determined that keeping tropical rain forests intact is a better way to combat climate change than replacing them with biofuel plantations.

It was undertaken by an international research team of botanists, ecologists and engineers from seven nations.

The study revealed that it would take at least 75 years for the carbon emissions saved through the use of biofuels to compensate for the carbon lost through forest conversion.

If the original habitat was carbon-rich peatland, the carbon balance would take more than 600 years.

London, Dec 2 : Archaeologists have uncovered rare sculptures from the late Stone Age at Zaraysk, 150 km south-east of Moscow in Russia.

According to a report by BBC News, the findings have yielded figurines and carvings on mammoth tusks, including a cone-shaped object whose function “remains a puzzle” to the archaeologists.

Such artistic artefacts have been found in the nearby regions of Kostenki and Avdeevo, but this is the first such discovery at Zaraysk.

The new artefacts, discovered by Hizri Amirkhanov and Sergey Lev of the Russian Academy of Sciences, include a mammoth rib inscribed with what appear to be three mammoths, a small bone engraved with a cross-hatch pattern, and two human figurines presumed to be female.

London, Dec 1 : One computer device could be called as being most ‘in touch’ with humans –the mouse, which celebrates it’s 40th birth anniversary today.

The first computer mouse, developed 4 decades ago, was a little wooden box with a single red button on top and a wire hanging from the back, because of which it was likened to a rodent.

And while computers have transformed from big white boxes to cool flat screens and laptops, the mouse has, more or less, stayed the same.

But, its designer, Douglas Engelbart, is not a rich man giving orders in a huge IT firm.

Brussels - The European Union's richest members must make concessions to their poorer peers if the bloc is to agree to a landmark deal on fighting climate change, a Polish minister insisted Thursday.

"We are as far from an agreement as we were in October ... It is really difficult to understand why a number of the most affluent member states ... are not really moving an inch," Polish Minister for Europe Mikolaj Dowgielewicz told journalists in Brussels.

New York, Nov 27 : A new keyboard called ‘Keyboard for Blondes’ has been developed with keys that have ‘Smart Blonde Button’ and ‘Somewhat Useless Key’, written on them.

The keyboard, which comes in a bubblegum-pink colour and is priced at 50 dollars, can even talk back and has funny titles for boring keystrokes like, “I need my space” bar.

The best features, however, are the keys dedicated to 100-times-a-day texts like “OMG,” “LOL” or “ZZZD,” which is girl-speak for boring date.

“It’s pink? That''s great,” the New York Daily News quoted blonde Samantha Dubin, 34, as saying wryly.
