IIT-I creates environmentally sustainable concrete with industrial waste
The institute said this innovative concrete can decrease carbon dioxide emissions by 80%, while reducing construction expenses by 20%. Additionally, it eliminates the requirement for water curing, which is particularly beneficial given current water scarcity concerns. The rapid strength development characteristic makes it ideal for time-sensitive construction applications, including military bunkers, bridges, emergency relief structures, precast railway sleepers, and highway pavement repairs.
The research team, led by Dr Abhishek Rajput, associate professor from the civil engineering department at IIT-I, utilised geopolymer technology to produce high-strength concrete with superior performance and durability compared to conventional concrete.
"This development is a step toward transforming the way we build our future infrastructure as stronger, faster, and greener. The goal is to find a practical solution that benefits both the environment and the construction industry," said Rajput.

The institute noted that ordinary Portland Cement Concrete (PCC) is responsible for approximately 8% of global carbon dioxide emissions, generating nearly 2.5 billion tonnes of carbon dioxide annually through cement manufacturing processes, including limestone burning and fuel consumption.
IIT-I director Prof Suhas Joshi said, "This is an excellent example of how IIT Indore is contributing to national priorities through sustainable technology. Such developments align with India's vision for green infrastructure and carbon neutrality."

TN to host one of five carbon capture testbeds for cement industry
CHENNAI: Tamil Nadu has been selected as one of the five locations in India to host a pioneering Carbon Capture and Utilisation (CCU) testbed aimed at reducing carbon dioxide (CO2) emissions in the cement sector, which contributes nearly 7-8% of the country's industrial carbon emissions. The testbed will be established at Ultratech Cement's Reddipalayam plant in Ariyalur district, with technical support from the Indian Institute of Technology Madras (IIT-M) and the Birla Institute of Technology and Science (BITS), Pilani, Goa campus. The initiative is part of a national programme spearheaded by the Department of Science and Technology to validate and demonstrate CCU technologies. These technologies aim to capture CO2 emissions and convert them into value-added products such as synthetic fuels, urea, soda ash, concrete aggregates, and food-grade CO2. At the Reddipalayam site, the testbed will trial an oxygen-enriched combustion-based kiln burning system. The captured CO2 – up to 2 tonnes per day – will be mineralised using concrete blocks, waste concrete fines, and concrete plant sludge. Besides Tamil Nadu, CCU testbeds are also being set up in Chittorgarh (Rajasthan), Sundergarh and Rajgangpur (Odisha), and Kurnool (Andhra Pradesh), each testing different technological solutions. Union Minister for Science and Technology and Earth Sciences Jitendra Singh said the DST is currently processing financial sanctions for the projects.

Watch the Earth split in real time: First-ever video reveals 2.5-meter fault slip in seconds caused by an earthquake
In March 2025, central Myanmar was struck by a powerful 7.7 magnitude earthquake—the strongest to hit the region in over a century and one of the deadliest in its modern history. What sets this seismic event apart is the capture of the fault's sudden rupture in real time by a nearby CCTV camera, marking the first-ever video evidence of such rapid ground movement during an earthquake. The footage vividly shows the Earth's surface splitting and slipping sideways by an impressive 2.5 meters in just 1.3 seconds. This rare visual record provides scientists with an unprecedented opportunity to study the detailed mechanics of earthquake fault slips, advancing our understanding of seismic behaviour and potentially transforming how future earthquakes are analysed and predicted. Myanmar earthquake and rare real-time footage of 2.5 metre fault On March 28, 2025, the Sagaing Fault near Mandalay, Myanmar's second-largest city, ruptured in a strike-slip earthquake where two blocks of earth slid past each other horizontally. This earthquake was both powerful and deadly, shaking the region unlike any event in recent memory. What makes this event groundbreaking is the CCTV footage that captured the fault slipping in real time, a phenomenon never before recorded on video. Unlike previous studies relying on distant seismic sensors, this footage offers a direct visual record of the fault movement. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Great news for Filipinos!

The slip lasted only 1.3 seconds, confirming a pulse-like rupture — a short, intense burst of movement traveling along the fault, similar to a ripple across a rug. The study also showed the fault slip path was subtly curved, challenging earlier ideas of purely linear fault ruptures and aligning with geological observations worldwide. New frontiers in earthquake science and future research This first-of-its-kind video observation offers powerful new tools for seismologists to understand fault behavior and earthquake mechanics . Capturing such detailed fault movement in real time will improve earthquake models and help better predict the ground shaking in future events, which is crucial for disaster preparedness. The research team plans to further explore the factors controlling fault slip shape and speed through physics-based simulations, hoping to unlock deeper insights into earthquake dynamics globally.

Int'l genetic study predicts childhood obesity risk using Indian data
Cleared: dk Hyderabad: In a major study, an international team of over 600 scientists from 500 institutions developed a genetic test — polygenic risk score (PRS) — which can predict adult obesity as early as age five. The study analysed data from over five million (50 lakh) individuals worldwide, with significant representation from India. Scientists from city-based Centre for Cellular and Molecular Biology (CCMB) played a key role in characterising the genomes of Indian individuals, including those monitored for diabetes over the long term. The south Asian data shaped PRS, making the findings especially relevant to the Indian context, where obesity-related disorders like diabetes and cardiovascular disease are on the rise. The tool, shown to be twice as effective as previous models, offers the potential for early lifestyle interventions in genetically high-risk children.

Scientists worldwide worked with the largest and most diverse genetic dataset ever assembled, which included genetic data from the GIANT consortium and the consumer DNA testing company 23andMe. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 15 most beautiful women in the world Undo In a statement, CCMB said: "The PRS discovery could help identify children and adolescents already at higher genetic risk of developing obesity, who could benefit from targeted preventative strategies such as lifestyle interventions at a younger age. Additionally, this score is twice as effective as the previous best test at predicting a person's risk of developing obesity." "What makes the score so powerful is its ability to predict, around the age of five, whether a child is likely to develop obesity in adulthood — well before other risk factors start to shape their weight later in childhood. Intervening at this point can have a huge impact," University of Copenhagen's NNF Center for Basic Metabolic Research (CBMR) assistant professor Roelof Smit, who is the lead author of the research published in the journal 'Nature Medicine', said. Indian Representation in the Study The pattern of obesity in India differs notably from that in Europe, with Indians tending to have more central (abdominal) obesity. Earlier studies by Dr Giriraj Ratan Chandak at CCMB showed that the genetic basis of non-communicable diseases varies significantly between Indians and Europeans. In the latest study, researchers at CCMB, led by Dr Chandak, characterised the genomes of the Indian population, including individuals with diabetes as well as those with normal blood glucose levels. These individuals were followed for nearly 20 years, providing a unique opportunity to investigate the genetic basis of obesity in Indians. Several obesity-associated genetic changes were identified and used to develop PRS for Indians, effectively creating a "virtual individual" to model obesity risk. The Indian data served as a representative subset for the South Asian population in the global study, making the findings more applicable to India and neighbouring countries. The researchers also examined the link between a person's genetic risk of obesity and the effectiveness of lifestyle-based weight-loss interventions, such as diet and exercise. They found that individuals with a higher genetic risk of obesity responded better to interventions — but also tended to regain weight more quickly once those interventions ended. The study further highlights the role of population ancestry in predicting obesity risk. Despite using a globally representative dataset, PRS performed more accurately in individuals of European ancestry than in those of other ancestries, including South Asians. Many gene variants associated with obesity in Europeans do not have the same effect in Indians, reflecting the unique pattern of obesity observed in the Indian population. "The observations made in this study are consistent with our earlier findings," Dr Chandak noted.
