Sunlight, not bacteria, key to CO2 in Arctic

Last Updated: Friday, August 22, 2014, 18:58

Sunlight and not bacteria is the key to triggering the production of carbon dioxide (CO2) from material released by Arctic soils, says a significant study.

Fuel cell technology gets a boost

Last Updated: Friday, August 22, 2014, 18:52

In an impetus for fuel cell technology to build "smart" cars, scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis.

`Sponge` plastic to soak up CO2, reduce pollution

Last Updated: Monday, August 11, 2014, 13:13

You have blamed plastics all along for increased pollution but researchers have now made a material - inspired by the plastics used in food containers - that soaks up carbon dioxide (CO2).

Sunderbans mangrove trees losing capacity to absorb CO2: Study

Last Updated: Monday, August 04, 2014, 10:13

The vast mangrove forest in the Sunderbans is fast losing its capacity to absorb carbon dioxide, one of the main greenhouse gases, from the atmosphere due to rise in the salinity of water, rampant deforestation and pollution, a study has found.

Mars 2020 rover will carry tools to make oxygen

Last Updated: Friday, August 01, 2014, 04:43

The suite of space-age tools loaded on NASA`s next robotic vehicle, bound for the Red Planet in 2020, will include a device for making oxygen out of carbon dioxide.

Artist develops first ever man-made leaf that could provide oxygen during space travel

Last Updated: Wednesday, July 30, 2014, 17:23

In a path-breaking innovation, Royal College of Art graduate Julian Melchiorri developed the first man-made, biologically functional leaf that takes in carbon dioxide, water, and light and releases oxygen.

Carbon dioxide can be future fuel source

Last Updated: Wednesday, July 30, 2014, 16:36

In a significant breakthrough, scientists have synthesised a catalyst that improves the system for converting waste carbon dioxide into syngas -- a precursor of gasoline and other energy-rich products.

`Natural cooling fluctuation` masked greenhouse effect during last decade: Study

Last Updated: Tuesday, July 22, 2014, 17:38

A new study has revealed that a natural cooling fluctuation between 1998 and 2013 largely masked the warming effects of a continued increase in man-made emissions of carbon dioxide and other greenhouse gases.

Plants` size, age impact productivity more than climate

Last Updated: Monday, July 21, 2014, 12:36

A new study has revealed that the size and age of plants has more impact on their productivity instead of climate that has a relatively minor direct effect on net primary productivity.

Ants can trap carbon for us

Last Updated: Thursday, July 17, 2014, 14:31

The tiny ants may be derided by all, but they play a very important role in making the earth habitable by assisting in the gradual reduction of atmospheric carbon dioxide.

How plants respond to elevated CO2 levels

Last Updated: Monday, July 07, 2014, 15:23

Researchers have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere.
