Scientists have found a radiation-resistant bacteria can survive at least three years exposed in orbit, suggesting simple life forms could manage the long journey between between Earth and Mars unprotected.

The Japanese scientists behind the research said Wednesday the finding lends credence to so-called "panspermia theory", which posits that microbes can travel from one planet to another, seeding life on arrival.

To test the theory, the researchers deposited a bacteria called Deinococcus radiodurans outside the International Space Station at an altitude of 400 kilometres (250 miles) from the Earth.

Despite enduring the harsh environment of outer space and exposure to strong UV and large temperature changes, the bacteria was still alive in parts after three years.

"I knew it would survive after carrying out various experiments in the lab, but when it came back alive, I was relieved," Akihiko Yamagishi, study author and emeritus professor at Tokyo University of Pharmacy and Life Sciences, told AFP.

The results show that the bacteria could weather a journey between Mars and Earth, and opens up intriguing possibilities, he said.

"Everyone thinks the origin of life started on Earth, but the new findings indicate that other planets could also be where life began."

Yamagishi and his team hope to carry out similar experiments outside the Van Allen radiation belt, which would expose the bacteria to even more radiation.

Scientists believe that more than three billion years ago Mars was much warmer than today and was covered in rivers and lakes, conditions which could have led to simple microbial life.

The discovery, published Wednesday in the journal Frontiers in Microbiology, comes with Mars back in the headlines as three missions head for the Red Planet.

They include the Hope probe from the United Arab Emirates, the Tianwen-1 from China and Mars 2020 from the United States, all of which are taking advantage of a period when the Earth and Mars are nearer to each other than usual.

Bacteria can survive cosmic trip: International Space Station study

India's Defence Research and Development Organisation (DRDO) has devised an ultraviolet sanitisation system to sanitise all electronic gadgets, currency and papers. The UV cabinet will be automated, contactless.

The Defence Ministry has developed this system as the country fights coronavirus outbreak and the system will be called Defence Research Ultraviolet Sanitiser (DRUVS).&nbsp;

DRUVS will provide a 360-degree exposure of the UV rays to the objects kept inside the cabinet. The automatic device will go into sleep mode after the sanitisation is done, this means the operator does not need to wait till it gets over.&nbsp;

The items DRUVS can sanitise: Mobile phones, iPads, laptops, currency notes, cheque leafs, challans, passbooks, paper, envelopes, etc.

India's COVID-19 tally continued to rise with the total number of confirmed cases touching 67,152 on Monday, data on the Union Ministry of Health and Family Welfare website showed.&nbsp;

Of the total cases in the country, 44,029 are active cases while 20,917 individuals have been cured and discharged from the hospitals. The death toll has mounted to 2,206 while one person has migrated to another country, according to the data released by the Health Ministry.

India added 4,213 new Covid-19 cases over 24 hours, according to the Union Ministry’s 8:00 am update on May 11.
