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]

Prime Minister Narendra Modi on Friday congratulated the Indian Space Research Organisation (ISRO) after the successful launch of the GSLV-F17 rocket carrying the EOS-05 Earth observation satellite, describing the achievement as a proud moment for the nation.

The GSLV-F17 lifted off at 2:55 a.m. IST from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The EOS-05 satellite was subsequently placed into its designated sub-geosynchronous transfer orbit.

PM Modi praises ISRO’s growing capabilities

In a post on X, PM Modi said the successful mission reflected the excellence, innovation and expanding capabilities of India’s space sector.

Yet another outstanding achievement by ISRO and a proud moment for our nation.

He also highlighted the growing partnership between ISRO and Indian industry, saying it was strengthening India’s space programme and expanding capabilities across the wider space ecosystem.

The prime minister described the successful launch of GSLV-F17 carrying EOS-05 as another outstanding achievement by ISRO and a matter of national pride.

EOS-05 strengthens earth observation capabilities

According to the report, EOS-05 is India’s first-ever imaging satellite from geosynchronous orbit. The satellite is designed to provide continuous observation of the country from an altitude of nearly 36,000 km above Earth.

The mission is expected to strengthen India’s earth observation capabilities and support advanced imaging and observation applications.

ISRO Chairman Dr V Narayanan expressed satisfaction with the mission, saying the satellite was precisely injected into its intended orbit.

Mission Director Thomas Kurian described the launch as a significant milestone for the GSLV programme. He said it was the 19th flight of the GSLV and noted that EOS-05 is the heaviest satellite the launch vehicle has placed into a geosynchronous transfer orbit or sub-GTO orbit.

GSLV-F17 launch vehicle details

The GSLV-F17 stands 51.7 metres tall and has an approximate liftoff mass of 420.5 tonnes.

Science and Technology Minister Jitendra Singh also congratulated the ISRO team following the successful mission. He described EOS-05 as a state-of-the-art Earth observation satellite capable of advanced imaging across visible, infrared, multispectral and hyperspectral bands.

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.
