Indian scientists reveal how Earth's most ancient organisms endure extreme conditions
Scientists hope to uncover strategies that could inform innovations in medicine, environmental conservation, and the search for life beyond Earth
Indian researchers under the Department of Science and Technology (DST) have unveiled key insights into how some of Earth's most ancient organisms, archaea, survive extreme environments.
Their findings highlight the sophisticated toxin-antitoxin (TA) systems that enable these microorganisms to adapt to harsh conditions. This is reported by IANS, a partner of TV BRICS.
Archaea, derived from the Greek word for "ancient things," represent one of the oldest forms of life on the planet. These microorganisms, often thriving in extreme habitats like volcanic springs, acidic hot pools, and hypersaline environments, offer clues about life's resilience in hostile conditions.
The research focused on the heat-loving archaeon Sulfolobus acidocaldarius. This organism, found in geothermal areas such as the volcanic pools, survives temperatures soaring to 90°C.
The study delved into the VapBC4 TA system of S. acidocaldarius, uncovering its crucial role in surviving heat stress. The VapC4 toxin was found to halt protein production during stressful conditions, conserving energy and preventing the formation of damaged proteins.
These findings not only deepen understanding of archaea but also hold potential applications in biotechnology and astrobiology. By studying how life endures extreme conditions, scientists hope to uncover strategies that could inform innovations in medicine, environmental conservation, and the search for life beyond Earth.

Ashok MondalNID Director"Signing this Memorandum of Understanding between the National Institute of Design (NID) and TV BRICS marks a pivotal milestone in advancing design diplomacy across the BRICS media space. This moment is especially significant as India hosts the 18th BRICS Summit, following India’s assumption of the BRICS chairship under the visionary leadership of Prime Minister Shri Narendra Modi. The partnership directly embodies his call to elevate Indian design standards through 'Design in India, Design for the World'. Through the global reach and broadcast capabilities of TV BRICS, we are excited to showcase the extraordinary visual storytelling, films, and design research of NID’s Film and Video Communication students to an international audience, while also welcoming and screening film works from BRICS network countries at NID Ahmedabad. This reciprocal exchange strengthens our shared commitment to educational, cultural, and artistic collaboration, fostering sustainable connections among global creative communities. NID Ahmedabad looks forward to leveraging this partnership to deepen cross-cultural dialogue, build international expert networks, and unlock transformative opportunities for filmmakers, researchers, and faculty across member nations" -

So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification" -
