NASA gets the credit for the ISS, but the actual breakthrough analysis of how these bacteria mutated was a collaborative masterclass led by IIT Madras. The study, published in the journal Microbiome, was co-led by Prof. Karthik Raman (IIT Madras) & Dr. Kasthuri Venkateswaran (a legendary Indian origin scientist at NASA's JPL). They found that the ISS strains developed a stress-response shield. In the high radiation, low gravity environment, the bacteria became Pathogen Prime & started assisting other harmful bacteria to survive, creating a microbial mafia that protects its members from the station’s cleaning protocols.
🚨: Scientists discovered that the bacteria living on the International Space Station have mutated into a species that doesn't exist on Earth.

A grown man tossing his opponent’s King who’s half his age into the crowd. Real classy, Hikaru. The hate Magnus and Hikaru have for India’s Gukesh is just unreal. #Chess
Community note
Prior to the event, the match’s organizers encouraged the winner of the game to throw the king into the crowd as a special gimmick to draw fan interest. Despite being instructed to celebrate, Hikaru supposedly apologized to Gukesh after the conclusion of the event for this. indianexpress.com/article/sports…

How does digestion work & is it affected by microgravity?🤔 In the latest STEMonstration video, ISRO (Indian Space Research Organization) astronaut Shubhanshu Shukla dishes on nutrition & how the body digests food in space. Hungry for more? Visit conta.cc/4lexreY.

Science from space - one of the highlights of this mission was conducting science in microgravity. Simple experiments become complex due to the environment of microgravity. Since everything floats, nothing would break if you leave it but would surely float away and you may end up spending half of your day searching for the item (Not saying it happened @) Here I am working in the LSG (Life Sciences Glovebox) that is used for experiments that need containment due to a higher hazard level. Microgravity causes muscle atrophy due to reduced load on the muscles in the environment of microgravity. Here on Earth our muscles are always under 1g load but in space this vanishes. Astronauts have to exercise regularly to preserve muscle mass. But even the exercise does not help the stabilizer muscles. Researchers from InStem, India developed the experiment to study the effect of natural supplements on stem cells in microgravity with an aim to accelerate muscle repair. In the LSG you prepare everything outside first and once all the equipment is ready you follow sterile technique and insert them in the LSG. Once done, you insert your arms in the gloves and get on a headset talking to a ground co-ordinator throughout the experiment to clarify any queries or concerns. They also get to see what you are doing through a camera. For perspective last image shows the correct orientation and I am on a wall. Really cool to hang on a wall and do science- something only possible in space. #space #shux #shubhanshushukla #scienceinspace #space_station #iss #india
