‘Water bear’ brought back to life 30 years after freezing in Antarctica

Japanese scientists at the National Institute of Polar Research have successfully brought a frozen animal back to life.

Scientists at Japan's National Institute of Polar Research successfully revived a 'Tardigrade' which they collected from Antarctica.

The Tardigrade had been frozen for 30 years.

Tardigrades, more widely known as 'water bears' are tiny creatures, usually around 0.5mm in length.

A tardigrade can go years without food or water and can endure extreme radiation and temperatures.

The creatures feed on plant cells and algae.

The longest revival of a tardigrade was previously nine years, this breakthrough is the first-ever successful revival after 30 years.

A 'water bear' is short and stumpy with eight legs – usually with four to eight claws or suction disks.

NASA recently did an experiment where they sent 5,000 tardigrades into space.

They were able to survive the extreme pressure and vacuum of space due to their ability to survive high-stress environments.

In another scientific breakthrough NASA has found that organic salt might exist on Mars – which would mean some form of life could have resided there too.

Researches announced their salt findings at the end of May, they say it could either be a result of geological processes or remnants of ancient microbial life.

NASA has found organics like this before, but findings of organic salts could be what we need to understand about the red planet's habitability.

The researchers have published the exciting findings in the Journal of Geophysical Research: Planets at the end of March.

James Lewis, lead author of the new paper, said: "If we determine that there are organic salts concentrated anywhere on Mars, we’ll want to investigate those regions further, and ideally drill deeper below the surface where organic matter could be better preserved.

"We’re trying to unravel billions of years of organic chemistry, and in that organic record there could be the ultimate prize: evidence that life once existed on the red planet."

If the red planet was ever home to life, chemical fingerprints would be left behind in the form of organic compounds like these ones.

Experts are currently trying to piece together the miniscule fragments of organics that they find, but ultraviolet radiation from the sun on Mars' is breaking drown the compounds – making the search for organics extremely challenging.

Although its difficult, it can and has been done before.

Back in 2018, NASA's Curiosity rover discovered organic compounds on Mars which all contained carbon, an essential for life as we know it on Earth.
