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]

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.

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.

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.
