Keeladi finds, backed by radiocarbon dating, unveil thriving 6th-century BCE settlement in Tamil Nadu
The archaeological site of Keeladi in Madurai has opened a new chapter in understanding Tamil Nadu's past.
Radiocarbon dating
by the US laboratory Beta Analytics has confirmed that the settlement dates back to the 6th-century BCE — making it contemporary with the urbanisation of the Gangetic plains — and remained a thriving center until the 2nd-century CE.
Of the 29 radiocarbon samples analysed by the
Tamil Nadu state department of archaeology
since the 2017-18 excavation season, the earliest dates back to 580 BCE and the most recent to 200 CE. Large brick structures from the Sangam Age unearthed at the site reflect the growth of an industrial and urban community, matching descriptions in
Sangam literature
.
'Most samples above the brick structures date to after the 3rd-century BCE, while those below go as far back as the 6th-century BCE,' said K Rajan, an archaeologist and advisor to the state's department of archaeology. 'This places Keeladi alongside the Gangetic plains in what is called India's second urbanisation.'

Researchers are also close to reconstructing the face of a person who lived in the settlement, using 3D technology and anthropometric measurements from a human skull unearthed at the nearby Kondagai burial site. 'Based on the skull, we will reconstruct the age, dietary pattern, determine the gender, and actual face of the person,' said Rajan.
The state's department is currently working with more than 20 research institutions from India and abroad — including Liverpool University in the UK, University of Pisa in Italy, Field Museum in Chicago, French Institute of Pondicherry, IIT Gandhinagar, and Deccan College — to piece together life in Keeladi in 580 BCE. Scientists from Madurai Kamaraj University are also investigating human and animal DNA to uncover migration patterns of the ancient population.
Live Events
A range of artefacts — glass, ivory, pearl and terracotta beads; seals; dice; and unidentified copper coins — highlights a sophisticated society with a rich material culture. Gold and ivory finds suggest the people were wealthy, while the discovery of Tamil-Brahmi inscribed potsherds dates the script back to the 6th-century BCE. 'It shows Keeladi was an urban settlement with a literate society and a community of artisans,' said R Sivanandam, joint director of the state archaeology department. 'It was an industrial hub along an ancient trade route linking the east port of Alagankulam to Muziris on the west.'
Indologist R Balakrishnan explained: 'Keeladi has proved that Sangam literature was a lived experience of ancient Tamils and not imaginative stories.' Furthermore, dice made of terracotta and ivory — a form of entertainment — were also recovered. 'Kalithogai, the sixth of the eight anthologies of Sangam literature, makes a mention of such dice games.'
Other sites — Kodumanal, Porunthal, Sivagalai, Adichanallur and Korkai — have also produced dates from this period. 'Korkai has produced a date as early as 785 BCE, suggesting Sangam-age urbanisation was widespread.' Rajan added.
Despite 10 excavation seasons, only 4% of the total 110 acres at the site has been excavated. The state plans to continue its investigations and has set up a museum to showcase the finds — with a first-of-its-kind on-site museum in the works. 'Tamil Nadu has endured archaeological apathy for far too long until Keeladi sparked a wave of interest in the state's past,' said Balakrishnan. 'Keeladi is the first site that transformed the understanding of archaeology in Tamil Nadu.'

New study suggests fungi are more complex than experts thought
Visakhapatnam: Dr Belle Damodara Shenoy, principal scientist at the CSIR-National Institute of Oceanography Regional Centre, Visakhapatnam, has a new publication on rethinking the 'new' in fungal species. The study stressed the importance of equitable global access to molecular technologies and infrastructural resources, particularly in biodiverse, yet under-resourced regions such as India. This will help foster broad engagement in fungal systematics and ensuring more comprehensive biodiversity assessment and conservation efforts. According to Dr Shenoy, an illustrative example is the colletotrichum gloeosporioides species complex. Once regarded as a single, widely distributed pathogen, it has now been split into multiple genetically distinct species. The study shows how molecular tools revealed species such as C. asianum, C. fructicola and C. siamense, which were previously grouped under one name because of their similar appearance. "As we confront biodiversity loss and climate uncertainty, understanding fungi—the hidden engineers of ecosystems—has never been more critical," Dr Shenoy noted, calling for equitable access to subsequent technologies, regional bioinformatics hubs and collaborative research models that include scientists from the global south. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Play Chess on Your PC, Free Play Classic Chess Install Now Undo Published in Mycological Spectrum, the official journal of the Association of Fungal Biologists (AFB), Dr Shenoy's article examines what constitutes a species in an era defined by genetic sequencing and asks whether the term 'new species' carries the same weight today as it once did. "The discovery of fungal species has outpaced our tools for accurately defining them. Historically, fungi were classified on observable traits—spore structure, growth patterns, pigmentation. But these morphological methods are no longer sufficient. Advances in molecular biology, particularly DNA bar coding using the internal transcribed spacer region, have upended traditional taxonomy. Researchers now use techniques such as genealogical concordance phylogenetic species recognition and coalescent-based models to uncover hidden, cryptic diversity," said the NIO principal scientist. "The pendulum may be swinging too far in the other direction. With a surge in DNA-based identifications, there is growing concern over taxonomic inflation—where minor genetic differences are mistaken for species-level divergences. A species is what a fungal taxonomist says it is; subjectivity remains inherent in the process," he added. Coalescent-based methods offer a statistical remedy by modelling gene flow and population divergence, but they demand computational power and bioinformatics expertise that are often unavailable in biodiversity-rich yet resource-poor regions. What is the way forward? Dr Shenoy advocates an integrative, eco-evolutionary approach—fusing molecular data with ecological context and classical morphology. This holistic method promises more robust, meaningful species classifications and deepens understanding of fungal biodiversity, with implications for agriculture, medicine and conservation. "The challenge, however, is accessibility. Countries like India—home to immense fungal diversity—often lack the infrastructure and training needed to participate fully in this genomic era of taxonomy. There must be equitable access to sequencing technologies, regional bioinformatics hubs and collaborative research models that include scientists from the global south," Dr Shenoy added.

'Neuralink babies'? Scale AI's Alexandr Wang says he is waiting for Elon Musk's brain chips before having kids
In a statement that straddles science fiction and near-future reality, Scale AI founder Alexandr Wang has revealed he's putting off parenthood—for now. But not because of career demands or personal timing. His reason? He's waiting for Elon Musk 's Neuralink to become mainstream. Yes, Wang wants his future children to be among the first humans enhanced by brain-computer interfaces from birth. During a recent appearance on The Shawn Ryan Show , the 28-year-old tech prodigy shared a vision that feels pulled from the pages of a futuristic novel. 'When we get Neuralink and we get these other technologies, kids who are born with them are gonna learn how to use them in like crazy, crazy ways,' Wang said, explaining that the first seven years of life—when neuroplasticity is at its peak—present the most fertile ground for integrating superintelligence into the human experience. Neuralink, Meet Nature Neuralink, founded by Elon Musk, is currently trialing a brain-chip implant the size of a coin. Though still in early clinical stages, the device has already shown stunning potential: one patient with ALS reportedly edited a video using only his mind. But Neuralink isn't alone. Synchron, backed by heavyweights like Jeff Bezos and Bill Gates, is collaborating with Apple to help patients with disabilities use iPhones through brain signals. Motif Neurotech, another contender, is developing a neurostimulator that treats severe depression and functions like a pacemaker for the brain. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Buy Brass Idols - Handmade Brass Statues for Home & Gifting Luxeartisanship Buy Now Undo Wang, who is also taking on a new role at Meta to lead its superintelligence initiatives, seems to believe these brain-machine hybrids are not just medical miracles—they are the future of human learning, cognition, and possibly even evolution. Born to Compute? His vision hinges on a well-documented trait: the astonishing neuroplasticity of young brains. A 2009 study published in Brain Dev. found that children's brains, particularly in the early years, are primed for adaptation. This plasticity not only helps kids learn languages or recover from injury but, in Wang's vision, could also help them learn how to "think" alongside or even through artificial intelligence. It's a radical idea—one that flips the conventional approach to parenting. Instead of shielding children from screen time or tech overload, Wang imagines a future where babies are born wired for the digital age, quite literally. Ethics, Science, and the Silicon Valley Dream As startling as Wang's perspective may seem, it's emblematic of a growing mindset in tech circles: that human limitations are solvable problems. But while Wang may be planning for AI-enhanced progeny, ethical concerns continue to hover over Neuralink and its competitors—from long-term brain health to consent, privacy, and the ever-blurring boundary between human and machine. Still, in a world racing toward a post-human horizon, Alexandr Wang's statement isn't just provocative—it might be prophetic. The question isn't whether Neuralink babies will happen. It's who dares to go first. And Wang, it seems, is ready to raise the world's first AI-native child—as soon as the software is ready.
