Titagarh (West Bengal), May 9, 2017: India is preparing a law for safeguarding its interest in Antarctica, an official of the Ministry of Earth Sciences (MoES) said here on Tuesday.

“India doesn’t have laws for Antarctica. We are preparing it and it is in circulation in the , law ministry,” MoES secretary Madhavan Nair Rajeevan told the media.

“The law entails regulating our activities. When we go there if we do a mistake, what will happen, what to do. It is about safeguarding our own interests,” he said.

Rajeevan said India is also poised to expand its research activities in the coldest continent.

Maitri, which is India’s second research station in Antarctica as part of the Indian Antarctic Programme, will be replaced by a new one in the next few years.

“The Maitri station will be replaced by a new station in the next three-to-four years. Scientific activities will be expanded. We are also planning to buy a ship which can go to Antarctica,” Rajeevan added. (IANS)

Using a special type of radar, researchers have discovered the invisible footprints hiding since the end of the last ice age — and what lies beneath them.

The fossilised footprints reveal a wealth of information about how humans and animals moved and interacted with each other 12,000 years ago, according to the study published in the journal Scientific Reports.

“We never thought to look under footprints, but it turns out that the sediment itself has a memory that records the effects of the animal’s weight and momentum in a beautiful way,” said study lead author Thomas Urban from Cornell University in the US.

“It gives us a way to understand the biomechanics of extinct fauna that we never had before,” Urban said.

The researchers examined the footprints of humans, mammoths and giant sloths in the White Sands National Monument in New Mexico.

Using ground-penetrating radar (GPR), they were able to resolve 96 per cent of the human tracks in the area under investigation, as well as all of the larger vertebrate tracks.

“But there are bigger implications than just this case study,” Urban said.

“The technique could possibly be applied to many other fossilised footprint sites around the world, potentially including those of dinosaurs. We have already successfully tested the method more broadly at multiple locations within White Sands,” Urban added.

“While these ‘ghost’ footprints can become invisible for a short time after rain and when conditions are just right, now, using geophysics methods, they can be recorded, traced and investigated in 3D to reveal Pleistocene animal and human interactions, history and mechanics in genuinely exciting new ways,” said study co-author Sturt Manning.

GPR is a nondestructive method that allows researchers to access hidden information without the need for excavation.

The sensor – a kind of antenna – is dragged over the surface, sending a radio wave into the ground. The signal that bounces back gives a picture of what’s under the surface. (IANS)
