Washington, Dec 18 : A new research has determined that ocean acidification could result in broader disruptions of biological processes in the oceans.

The research was conducted by Donald Potts, a professor of ecology and evolutionary biology at the University of California, Santa Cruz, US.

Ocean acidification is one of the side effects of the rising concentration of carbon dioxide (CO2) in Earth''s atmosphere due to the burning of fossil fuels.

New Delhi, Dec 17 : Tejas, India's indigenous Light Combat Aircraft (LCA), has achieved a major milestone when its prototype landed at Leh air base in the high-altitude Ladakh region of Jammu and Kashmir.

"Tejas (LCA) programme reached a major milestone when the prototype vehicle PV-3 landed at Leh on December 13 this year at 1326 hours," Defence Research and Development Organisation (DRDO) officials said on Tuesday.

Washington, Dec 17 : Scientists from Imperial College London and the University of Edinburgh have found that tiny crystals found inside bacteria provide a magnetic compass to help them navigate through sediment to find the best food.

They believe that the research may provide vital clues explain biomagnetism - a phenomenon in which some birds, insects and marine life navigate using the magnetic field that encompasses the Earth.

The researchers focused their study on magnetotactic bacteria, which contain chains of magnetic crystals, called magnetosomes. They exist all over the globe, living in lake and pond sediments and in ocean coastal regions.

London, Dec 17 : Scientists have developed a bioelectronic sensor, the size of a postage stamp, which uses cell mitochondria to sniff out bombs and other explosives.

Common explosives detectors are not only expensive, but bulky and complex as well and thus become difficult for use in the field.

However, now the new sensor invented by Shelley Minteer and her colleagues at St Louis University in Missouri might reform the way detection of explosives is conducted.
