New Delhi, June 14 (India Science Wire): Intestinal health is known to be influenced by environmental, biological and genetic factors. A new study suggests that ethnicity – a cultural factor – may also have a role to play in keeping our stomachs healthy.

Gut microbes, especially bacteria, are essential to maintain good digestive health. Therefore, a study of bacteria and metabolites could yield important clues to any person’s health. Scientists at the Institute of Advanced Study in Science and Technology, Guwahati, have attempted to do this among members of tribal communities. They have found that the type of gut bacteria found among people vary with their ethnicity.

The study included 39 men and women belonging to five tribes – Tea-tribe (which has a Proto-Australoid origin), Bodo, Karbi, Tai-Phake and Tai-Aiton tribes of Mongoloid origin. All study participants were of rural background, practiced farming and were non vegetarian. Rice is their staple food along with cereals, vegetables and tubers. The study builds on earlier work done at the institute, which had shown a similarity in gut microbe profiles of the Tea-tribe and Tai-Phake and between Tai-Aiton, Bodo and Karbi tribes.

Individuals of same ethnic group had more similar profiles of gut bacteria and their metabolites. This has important implications for health. For instance, the metabolite profile of the Tea-tribe contained aniline, benzoate and acetaldehyde which may cause colorectal cancer. “This finding is significant as people from the community can be made aware of the risk they face and suitable preventive measures can be initiated such as regular follow-ups for any signs of the disease,” explained Dr. Mojibur R Khan, who led the study. Additionally, useful Lactobacillus and Roseburia bacteria or butyric acid supplements can be given to people to prevent colorectal cancer.

Regular analysis of metabolites could be cheaper way to keep track of persons who are at risk of acquiring a disease. On the other hand, more expensive tests to detect presence of cancer cells can be done only when there is a clear indication of disease.

The study offers hope to ethnic groups in India and around the world by encouraging researchers to identify population-specific disease markers through gut and metabolite profiling useful for prevention, early detection and intervention of disease. Subsequently, cheap diagnostic tests can be developed using the profiling data.

The team of researchers included Madhusmita Dehingia, Supriyo Sen, Bhuwan Bhaskar, Tulsi K. Joishy, Manab Deka, Narayan C. Talukdar. The study results have appeared in scientific journal Metabolomics. (India Science Wire)[/vc_column_text][/vc_column][/vc_row]

Indian-origin astronaut Anil Menon begins first mission to International Space Station

Indian-origin NASA astronaut Anil Menon has launched aboard Soyuz MS-29 on his first mission to the International Space Station, where he is expected to spend around eight months conducting research.

Indian-origin NASA astronaut Anil Menon has embarked on his first journey into space after successfully launching aboard Russia’s Soyuz MS-29 spacecraft to the International Space Station (ISS).

The mission lifted off from the historic Baikonur Cosmodrome in Kazakhstan at 8:17 PM on Tuesday. Menon was accompanied by Russian cosmonauts Pyotr Dubrov and Anna Kikina as the three-member crew began their expedition to the orbiting laboratory.

Crew to spend about eight months aboard ISS

The Soyuz MS-29 spacecraft is expected to dock with the International Space Station a little over three hours after launch. Once aboard the ISS, the crew will carry out a range of scientific research and technology demonstration projects during their mission.

The expedition is scheduled to last approximately eight months, with the crew expected to return to Earth in 2027 after completing their planned activities in orbit.

Menon’s maiden spaceflight marks a significant milestone in his astronaut career as he joins the International Space Station crew for long-duration research and operational work.

Indian astronaut Group Captain Shubhanshu Shukla, the first Indian to visit the International Space Station (ISS), will meet Prime Minister Narendra Modi this evening at his official residence in New Delhi.

PM Modi to host meeting with astronaut

According to officials, the meeting at 7 Lok Kalyan Marg is expected to take place between 5 pm and 5:30 pm. Shukla, who arrived in India on Sunday, will also be part of the National Space Day celebrations scheduled for August 23.

Warm welcome in India

The astronaut was greeted at the airport by his family, Science and Technology Minister Jitendra Singh, Delhi Chief Minister Rekha Gupta, and hundreds of citizens waving the national flag. Shukla had been in the United States for a year, preparing for the Axiom-4 mission, which launched from Florida on June 25 and docked at the ISS the next day. He served as the mission’s pilot.

Emotional note from Shukla

Before his return, Shukla shared an emotional post on Instagram, expressing mixed feelings of leaving his space colleagues while being eager to meet his loved ones and people of India. He also quoted a song from the film Swades, which he had chosen as his anthem on the launch day.

Parliament session on India’s space journey

In honour of Shukla’s mission, the Lok Sabha is holding a special session today to discuss “India’s first astronaut aboard the ISS – critical role of space programme for Viksit Bharat by 2047.” Union minister Kiren Rijiju said the discussion would highlight the importance of India’s space achievements and future goals.

Shubhanshu Shukla pens emotional note as he returns to India after space mission

Indian astronaut Shubhanshu Shukla penned an emotional Instagram post as he returned to India after his 18-day ISS mission, marking a milestone in India’s space journey.

Indian astronaut Group Captain Shubhanshu Shukla has shared an emotional Instagram post as he heads back home after completing his 18-day mission aboard the International Space Station (ISS).

Astronaut reflects on mixed emotions

In his heartfelt message, written from the aircraft, Shukla expressed the whirlwind of emotions he felt while leaving behind his fellow astronauts, who had been his family during the mission. “As I sit on the plane to come back to India, I have a mix of emotions running through my heart. I feel sad leaving a fantastic group of people behind who were my friends and family for the past year during this mission. I am also excited about meeting all my friends, family and everyone in the country for the first time post mission. I guess this is what life is — everything all at once,” he wrote.

Acknowledges support and inspiration

The astronaut thanked everyone for the love and support he received throughout his journey. He also recalled the words of his commander Peggy Whitson, saying, “Goodbyes are hard, but we need to keep moving in life. As my commander Peggy Whitson fondly says, ‘The only constant in spaceflight is change’. I believe that applies to life as well.”

Shukla ended his note with a line from the song Yun Hi Chala Chal from the film Swades, reflecting his spirit of resilience.

Link to India’s space ambitions

Shukla’s return comes at a crucial time as India advances its space programme. Prime Minister Narendra Modi had earlier mentioned that the astronaut would soon return and that he was tasked with documenting his training and ISS stay. This record will serve as a valuable reference for Gaganyaan, India’s first human spaceflight mission.

Over the past year, Shukla trained extensively at NASA, Axiom, and SpaceX facilities. His flight to the ISS as part of the Axiom 4 mission marked a milestone in India’s preparations for future human space exploration.

The Gaganyaan project aims to send Indian astronauts into orbit aboard an indigenous rocket. The government has also outlined plans for a Bharatiya Antariksh Station by 2035 and a crewed mission to the moon by 2040.
