To prevent infections from spreading, ants avoid infected members within colonies

[vc_row][vc_column][vc_column_text]When we talk about sixth sense, we say animals and insects have stronger sixth sense as compared to human beings, and yes it’s true. Ants, one of the tiniest creatures, have developed the ability to sense intuitively infections and flu before they occur.

A study published in US journal Science on Friday says that ants keep themselves away from other members of the colony when they suffer from communicable diseases.

Scientists performed research on ants in the laboratory to know in detail about their behavioural changes. They intentionally introduced a fungus in ant colonies and found that fungus-contaminated ants and uncontaminated ants both live away from each other. This behavioural change in the ants proves that they care for the members of their colonies and these changes protected the vulnerable members of their colonies.

Nathalie Stroeymeyt, an evolutionary scientist and lead researcher at the University of Lausanne in Switzerland said, “The isolation of sick individuals had been observed earlier in ants and honeybees.”

“But this is the first time we’re seeing behaviour changes in contaminated and healthy ants affecting their colonies’ social networks.”

Ants have high population counts, genetic similarities and frequent physical contact between individuals. The behavioural changes in ants are meant to prevent infections from spreading within colonies of social insects that are extremely vulnerable to infections.

According to Stroeymeyt, it is entirely possible that an ant would be able to detect a festering fungus on one of its colony members, just as easily as it would be able to smell a pathogen on its own body.

“Up to now, there was just not the technical methodology to measure their interactions at the colony level over extended periods of time,” said Nathalie Stroeymeyt.

Swiss researchers developed an automated tracking system in 2013 that let Stroeymeyt and her colleagues get detailed look at how 22 lab-reared ant colonies behave when disease is percolating in their midst. Stroeymeyt said, the team glued tiny 2D barcodes onto the ants’ thoraxes, which gave each insect a unique identifier — “just like a QR code.” A camera positioned above the ants’ snapped two pictures every second, and this technique recorded the position on each barcode and gave the researchers a wealth of data about the ants’ movements.

Few ants received a high dose of the fungus but more ants received a low dose that, the scientists believe, could help bolster their immunity from future infections.

“The ants’ immune system can deal well with this lower pathogen level, which provides a form of immune memory,” Sylvia Cremer, an evolutionary biologist at the Institute of Science and Technology, said in a media release.[/vc_column_text][/vc_column][/vc_row]

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.

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.

Group Captain Shubhanshu Shukla of the Indian Air Force has etched his name in history as the second Indian astronaut to travel to space. Launching aboard the SpaceX Crew Dragon on the Axiom-4 mission, Shukla began his journey from NASA’s Kennedy Space Center in Florida, from the very launchpad that propelled Neil Armstrong’s Apollo 11 moon mission in 1969.

Four decades after Wing Commander Rakesh Sharma became the first Indian to journey into space in 1984, Shukla’s mission marks a monumental milestone for India’s space ambitions. Speaking ahead of the mission, Shukla expressed the emotional weight of the moment, saying, “I carry with me not just instruments and equipment, but the hopes and dreams of a billion hearts.”

A multinational crew on a scientific journey

Group Captain Shukla is joined by Commander Peggy Whitson from the US, Slawosz Uznanski-Wisniewski from Poland, and Tibor Kapu from Hungary. The four-member crew is on a mission to the International Space Station (ISS), where they are scheduled to arrive after a 28-hour journey and dock around 4:30 pm tomorrow.

The fortnight-long mission includes the execution of 60 scientific experiments, with seven of them designed by Indian researchers. Shukla is also expected to engage in an interaction with a VIP from space during the mission, adding a special human touch to this scientific voyage.

A mission delayed, but not denied

The Axiom-4 launch had faced multiple delays due to unfavorable weather and technical complications. June 25 finally saw the successful launch, marking NASA’s sixth official date announcement for the mission.

Before lift-off, Shukla shared a heartfelt message with his family: “Just wait for me, I’m coming.” The Indian pilot had been under quarantine for over a month in preparation, ensuring he was in optimal health for the journey.

As the spacecraft orbits Earth en route to the ISS, India watches with pride and anticipation, inspired once again by the courage of its space pioneers.
