New bacterial species discovered aboard Tiangong Space Station by Chinese scinetists
Chinese researchers have found a new, previously unknown bacteria species on the Tiangong Space Station, a Chinese modular space station in low Earth orbit. These findings are recorded in the International Journal of Systematic and Evolutionary Microbiology. The discovery has been formally named as Niallia tiangongensis. These findings were made from the microbial samples collected from multiple surfaces across the space station during the Shenzhou 15 mission, which landed on Earth in June 2023.
Characterized as aerobic, spore-forming and rod-shaped, these bacteria are genetically close to Niallia circulans, a terrestrial strain, this space-borne bacterium shows several different mutations. These differences, say the scientists, contain potential for further developing the knowledge of microbial life outside Earth.
One notable trait of Niallia tiangongensis is its ability to hydrolyse gelatin, a biochemical process that could prove advantageous in nutrient-scarce settings. The bacterium further demonstrates specialized structural and functional divergence within two proteins crucial to biofilm development, defense against oxidative stress, and repair from radiation damage. These characteristics indicate special adaptations that can allow the organism to survive in space, where one is exposed to continuous bombardment by toxic radiation, microgravity, and scarce resources with which to fight survival.
Although it is the first such discovery on Tiangong, it is not unusual. Bacterial experiments on the International Space Station already have yielded new bacterial isolates, some of which will come in handy for future efforts to grow food on Mars. Even within the spotless walls of NASA clean rooms, places intended to be nearly microbe-free, researchers recently discovered 26 new species of bacteria.

T20 WC star Samson named ICC Men's Player of the Month for March

Dubai (PTI): India opener Sanju Samson was on Tuesday named ICC Men's Player of the Month for March, capping a stellar run that saw him play a defining role in the team's triumphant T20 World Cup campaign.
Samson did not get to play in the early part of the tournament but was the standout performer in the big games towards the end and helped India retain the title.
His latest honour also extends a unique streak, with players from different countries winning the award over the past five months including South Africa's Simon Harmer, Australia's Mitchell Starc, New Zealand's Daryl Mitchell and Pakistan's Sahibzada Farhan.
"Winning the ICC Player of the Month award is an incredible feeling, especially as it comes during what has been the most unforgettable phase of my cricketing journey. Playing a part in India's triumph at the Men's T20 World Cup was truly a dream realised, and it took some time for the magnitude of that moment to fully sink in," Samson said.
"This is an exciting era for Indian cricket, with immense talent across the board. I feel grateful for the opportunities I've received, and for the trust and support from my team-mates and coaching staff that have allowed me to perform at my best."
Not a regular part of the playing XI in the initial stages of the tournament, Samson was eventually called up for India's must-win Super 8 fixtures. After starting off with 24 against Zimbabwe, he picked form and didn't look back.
The opener missed out on a century against the West Indies by just three runs, but his attacking 97 not out set up India's spot in the semifinal.
A blistering 89 against England at the Wankhede helped India to 253 for 7, and the target proved elusive for the English who missed out by seven runs on March 5.
An equally amazing 89 was churned out during India's successful title defence in Ahmedabad, securing a 96-run win.
In the three crucial T20Is he was a part of in March, Samson notched up 275 runs at an astonishing average of 137.50 and a stunning strike rate of 199.27.
This is the first time that Samson has secured an ICC Men's Player of the Month honour.
New Zealand captain Melie Kerr won the women's honour for the third time, after an outstanding series against Zimbabwe and South Africa.
Taking over the white-ball teams from Sophie Devine, Kerr's captaincy seemed to have brought out the best in her with both the ball and the bat. In the Zimbabwe ODI series, she managed to snap 16 wickets in just three matches, including her career-best figures of 7/34.
Additionally, she also contributed with the bat, being the third highest run-scorer in the ODIs, scoring 140 runs across three games with an average of 46.67 in the counting month.
