Completed school in 9 years, MSc at 12, PhD at 21, worked at IIT Bombay as professor at 22, fired from job due to…; he is now... Some people are born geniuses. They complete their studies at a young age and achieve their goals and passions. Tathagat Avatar Tulsi, who was once hailed as a child prodigy in physics, now finds himself at an uncertain stage in life, presently unemployed. Right from childhood, his brilliant mind stood out from the rest. Born on September 9, 1987, in Bihar, Tulsi had already completed school studies when most children were barely starting out. While his initial success was newsworthy, his experience has now followed a surprising and unforeseen path. In this article, we will discuss the motivational story of an Indian genius, who completed school at 9, PhD at 21, became an IIT professor at 22, then got fired due to….; his name is.. Hailing from Bihar, Tathagat Avatar Tulsi was born on September 9, 1987. He exhibited extraordinary talent from a young age. Surprisingly, Tulsi finished his schooling at 9, a mere age when most of the students are barely starting out their academic journey. Soon after pursuing his school education at the age of 9, Tathagat Avatar Tulsi achieved another milestone. He completed his BSc at 11, and an MSc at 12 from Patna Science College. Not only this, Tathagat Avatar Tulsi further studied for a PhD at the Indian Institute of Science (IISc) in Bangalore and finished it when he was just 21 years old. Though he achieved everything so early in life, nowadays he is also struggling with unemployment. Avatar earned his PhD and authored his thesis on the subject, 'Generalizations of the Quantum Search Algorithm.' He co-authored a research paper with Lov Grover titled 'A New Algorithm for Fixed-point Quantum Search,' although it remained unpublished. A wave of good news returned to his life in 2010, when Tulsi was appointed as a contractual professor at the Indian Institute of Technology(IIT) Bombay. Life took an arduous turn in 2011 when his health started to deteriorate. He had a high fever, and it was diagnosed as an allergy. His sickness was the start of his tribulations. In 2013, on health grounds, Tathagat went on a four-year-long leave in Patna. Unfortunately, after his long leave, IIT Bombay laid off his services in 2019, bringing an effective end to his academic life at the institute. Going by the media reports, he is said to have earned the title of youngest PhD holder in India. Tathagat, who was once among the most gifted Asian kids, earning nicknames such as 'Superteen' by Science, 'Physics Prodigy' by The TIMES, and 'Master Mind' by The WEEK, now finds himself unemployed and seeking to recreate his life. In 2019, Tulsi's tenure at IIT came to an official end when he was released from his duties. Now, Tathagat Avatar Tulsi is moving into a new stage of life. No longer in school, he has shifted his attention to the study of law. His keen mind is looking for new possibilities, and many who were once inspired by him are observing, waiting to see what the future has in store for this once-great scholar.

Catfish species found in Ganga point to India's freshwater fish diversity
In the early 2010s, taxonomist Balaji Vijayakrishnan was stationed in Rudrapur, Uttarakhand, where he worked for a private company. Every weekend, he would pack a net, and some bags and leave on an impromptu fishing trip to remote locations along the Ganga river. Over three years, Vijayakrishnan amassed more than 300 specimens, amounting to roughly 30-40 species of loaches, catfishes and barbs. When he shifted base to Mumbai, the entire collection of specimens was sent to his parents' residence in Chennai. But in a cruel twist of fate, the Chennai floods of 2015 wiped out a majority of Vijayakrishnan's collection. Stored in containers of formaldehyde and ethanol, the specimens were arranged in the basement parking of the house. Floods in 2016 further reduced the collection to zero specimens. 'I don't know if I can ever get back that collection,' Vijayakrishnan said. Over the last decade, through annual visits, sometimes two-three trips a year, the independent researcher has been able to retrieve (in a sense) about 10% of the original collection. Most species were catfishes of the genus Glyptothorax and loaches of the genus Schistura. In March this year, the self-taught taxonomist, along with another researcher Gaurav Anil Shinde, published a research paper in the journal Zootaxa, describing two new species and revalidating a species of the Glyptothorax genus from the Ganga river basin. The two newly described species are Glyptothorax bhurainu and Glyptothorax himalaicus. The revalidated species is Glyptothorax dakpathari, named after its locality, which is the Dakpathar Barrage on the Yamuna river. The duo has three to four more papers in various stages of preparation for the genus Glyptothorax from the Ganga river basin. There will be three more new species, and a couple more revalidations, according to Vijayakrishnan. Hillstream catfish Catfishes are a group of ray-finned fishes found on all continents except Antarctica. Although they are believed to have lived in Antarctica millions of years ago when its weather was warmer. Majority of catfishes are bottom-dwelling and bottom-feeders, consuming organic debris, aufwuchs (animal and plant matter attached to submerged surfaces), smaller fish, insect larvae, and crustaceans. Many catfish species also indulge in scavenging, which helps keep water bodies clean and prevents excessive organic waste build-up, which could otherwise lead to oxygen depletion. These factors help regulate and maintain a balanced ecosystem. 'They (catfish) are characterised by the presence of barbels, which resemble a cat's whiskers, and hence their name,' said Heok Hee Ng, a biodiversity researcher at the Lee Kong Chian Natural History Museum of the National University of Singapore, not associated with the study. Scales are absent for these fishes, although some of them have bony plates covering their body. According to Ng, a prolific fish taxonomist and a specialist in the systematics of Asian catfishes, there are more than 3,000 species of catfishes known worldwide, with some estimates exceeding 4,000. Catfishes are a primarily freshwater group (although two of the 39 families inhabit marine waters). 'Catfishes are a major component of the freshwater fish biota in most systems, usually comprising about one-fifth of the total freshwater fish diversity,' he said. 'In India, there are more than 300 catfish species, although this number is likely a conservative estimate, given how little we understand catfish diversity in India,' Ng added. Glyptothorax belongs to a family of catfishes known as the Sisoridae. Sisorids are primarily hillstream catfishes, with many species inhabiting torrential hill streams. There are about 90-100 species globally, with a distribution that mirrors the Sisoridae, according to Ng. 'They are found in rivers throughout the entire southern arc of the Asian continent; from the Caspian drainages of Türkiye to eastern and southern continental Asia and the Greater Sunda Islands,' he said. 'In India, they are particularly diverse in the northeast, where 40-45 species are known. In the Ganga, so far, including the ones we have described, about 16 species are known,' Vijayakrishnan said. Sisorid catfishes display numerous adaptations to live in strong currents, one of which is the presence of the thoracic adhesive apparatus, or TAA, in the genus Glyptothorax. 'The TAA is an oval field of skin folds on the chest that help the catfish adhere to the substrate and prevent them from being washed away by the strong currents,' Ng said. The shape of the TAA is an important tool for differentiating between Glyptothorax species. Another key way is through the presence or absence of plicae, small notches on the underside of the fins that help them cling to rocks. In their paper, Vijayakrishnan and Shinde, revalidated Glyptothorax dakpathari, first described in 1976 and later synonymised with Glyptothorax gracilis, a species known from Nepal but also found in India. The plicae are absent in G gracilis, while they are present in G dakpathari. 'Unfortunately, the original description of the G dakpathari also says they are absent. A close examination of the type specimens of G dakpahtari reveals that it has plicae and is not a synonym of G gracilis,' Vijayakrishnan said. Fish diversity G himalaicus and G bhurainu specimens were collected from shallow, fast-flowing streams from the upper reaches of the Ganga basin in the Haridwar district of Uttarakhand. According to Vijayakrishnan, the Ganga river holds 'more treasures than most people understand.' 'So far, the number of fish species in the Ganga is known to be anywhere between 100 and 200. But it is severely underreported, in my opinion,' he said. The Brahmaputra river, in comparison, sees constant research activity, with 'at least a dozen new fish species described on an annual basis'. 'The Ganga is at least as biodiverse as the Brahmaputra or other rivers in northeast India,' Vijayakrishnan said. 'In addition to new species, there's a lot of obscure or lost species like G dakpathari. But no one has bothered to revalidate them when the material is very much evident,' he added. 'The discovery of new Glyptothorax species in the Ganga River drainage, India's most well-known river system, highlights how poorly we understand India's freshwater fish diversity,' said Ng. '[It] also shows that despite continued habitat degradation, discovering new species is still possible if one looks hard enough.' According to Ng, understanding catfish diversity will give greater impetus to conserve freshwater habitats. 'Given that freshwater systems globally, particularly in India, are under severe anthropogenic threat and that it would not be possible to conserve all freshwater habitats, better understanding catfish diversity will allow us to make better-informed decisions on the priority areas for conservation,' he said. Independent research As an independent researcher, Vijayakrishnan is met with numerous stumbling blocks in his efforts to spotlight the freshwater fish diversity in the country. A major deterrent is a lack of institutional backing. Even though there is published research under his name, without an official letterhead or email address, it is hard to access museums. 'I can't write a letter and say I want to examine these specimens. It doesn't sell, unfortunately,' Vijayakrishnan said. 'I don't think it is a flaw in the Indian system, I think it is a flaw with the system in general, globally.' Funding is the other hurdle. Currently, Vijayakrishnan fully finances his research, but he believes it is what will eventually slow them down. 'I'd love to go to Uttarakhand every month, but no chance that'll ever happen. I have to space it out, plan it carefully, and make sure I don't overspend,' he said. After completing the papers currently in progress, he wants to shift his focus from the Garhwal Himalayas (Western Uttarakhand) to the Kumaon Himalayas, which is closer to Nepal. New species are being discovered in Nepal, even in the Glyptothorax genus, according to Vijayakrishnan. 'We hope coordinated surveys in under-explored rivers such as the Ganga can be a major boost for [freshwater fish research],' he said.

Mammoths vs. Elephants: A detailed comparison on the basis of characteristics, habitat and more
Source: Wikipedia Mammoths and elephants are two of the most fascinating and iconic members of the elephant family and they even share many similarities yet exhibit distinct differences. While elephants roam the Earth today, mammoths lived thousands of years ago during the Ice Age and are now extinct. Comparing these prehistoric giants with their modern relatives helps us understand how they adapted to different environments, their physical traits, behavior and their place in natural history. This comparison sheds light on the characteristics, habitat,survival and challenges faced by these remarkable creatures. How mammoths and elephants are different Aspect Mammoths Elephants Physical Characteristics Thick, shaggy fur; long, spiraled tusks; stocky body with fat hump; smaller ears; built for cold Sparse hair; straighter tusks; larger ears (especially African elephants); adapted to warm climates Species & Classification Genus Mammuthus; extinct; famous species: woolly mammoth (Mammuthus primigenius) Genus Elephas (Asian elephants) and Loxodonta (African elephants); three living species; endangered Habitat & Distribution Lived in Ice Age tundras & grasslands of North America, Europe, northern Asia; cold, icy climates Found in sub-Saharan Africa (savannas, forests, deserts) and South/Southeast Asia (tropical forests) Diet & Behavior Herbivores; grazed cold-tolerant plants; lived in matriarchal herds; used trunks for feeding & social interaction Herbivores; varied diet including fruits and bark; matriarchal herds; behaviors include dust bathing and mud wallowing Extinction & Conservation Extinct ~4,000 years ago due to climate change and hunting; cold adaptations lost value Still alive; threatened by habitat loss, poaching, human conflict; conservation efforts ongoing Evolutionary Relationship Shared common ancestor with elephants; diverged millions of years ago; closely related genetically Closest living relatives to mammoths; evolutionary adaptations to warm climates Cultural & Historical Significance Featured in Ice Age art; used for tools and food by early humans Symbolize strength, wisdom, royalty; important in religion, folklore, warfare, and labor historically Adaptations Thick fur, fat layer, curved tusks for snow digging, smaller ears to reduce heat loss Large ears for heat dissipation, sparse hair, versatile trunks, strong legs and tusks adapted to warm environments Mammoths vs elephants: Key differences Physical characteristics Mammoths and elephants share similar body structures but have notable differences. Mammoths were generally covered in thick, shaggy fur to survive Ice Age cold, while elephants have sparse hair suited for warmer climates. Mammoths had long, curved tusks that spiraled more dramatically than elephants' straighter tusks. Their bodies were stockier with a hump of fat on their backs for insulation. In contrast, elephants have larger ears, especially African elephants, which help regulate body temperature. Both species have trunks and large, sturdy legs but mammoths were built to endure freezing conditions, whereas elephants are adapted to tropical and savanna environments. Species and classification Mammoths and elephants both belong to the family Elephantidae, making them close relatives. Mammoths fall under the genus Mammuthus, with the most famous species being the woolly mammoth, which lived during the Ice Age. In contrast, modern elephants belong to the genus Elephas which are Asian elephants and Loxodonta which are African elephants. There are three main living species: the African bush elephant, the African forest elephant,and the Asian elephant. While mammoths are extinct, elephants continue to survive but many species face threats and are considered vulnerable or endangered. Habitat and distribution Mammoths primarily lived in cold and icy environments during the Ice Age, such as the vast tundras and grasslands of North America, Europe and northern Asia. Their thick fur and fat helped them survive harsh, freezing climates. In contrast, modern elephants inhabit warmer regions. African elephants are found across sub-Saharan Africa in savannas, forests, and deserts while Asian elephants live in tropical forests and grasslands across South and Southeast Asia. Unlike mammoths, which are extinct, elephants still roam diverse habitats but face challenges due to habitat loss and human activity. Diet and behavior Both mammoths and elephants were herbivores, primarily feeding on grasses, leaves, shrubs, and bark. Mammoths grazed on tough and cold-tolerant plants and were found in Ice Age tundras while elephants consume a wide variety of vegetation depending on their habitat, including fruits and tree bark. Socially, both animals lived in herds led by a matriarch, showing strong family bonds and complex communication. They used their trunks for feeding, drinking and social interaction. While mammoths adapted to harsh and cold environments, elephants display behaviors suited to warmer climates, such as dust bathing and mud wallowing to regulate body temperature. Extinction and conservation Mammoths went extinct around 4,000 years ago, primarily due to climate change at the end of the Ice Age and hunting by early humans. Their cold-adapted traits became less useful as temperatures rose, leading to habitat loss. In contrast, elephants are still alive today but face serious threats from habitat destruction, poaching for ivory and human-wildlife conflict. Conservation efforts focus on protecting elephant habitats, enforcing anti-poaching laws and supporting breeding programs to prevent their decline. While mammoths are gone, the survival of elephants depends heavily on global conservation actions to ensure these majestic creatures do not face the same fate. Evolutionary relationship Mammoths and elephants share a common ancestor and belong to the same family that is Elephantidae. Their evolutionary paths diverged millions of years ago, with mammoths adapting to cold Ice Age environments while elephants evolved to thrive in warmer climates. Despite differences in appearance and habitat, their genetic makeup remains closely related. Modern elephants are considered the closest living relatives of mammoths. Advances in DNA analysis have even allowed scientists to study mammoth genes, offering insights into how these species evolved and adapted to their environments over time. Cultural and historical significance Mammoths have fascinated humans for thousands of years, appearing in prehistoric cave paintings and ancient tools made from their bones and tusks. They played a key role in Ice Age cultures as a source of food, materials, and inspiration. Elephants have held cultural importance across many civilizations- symbolizing strength, wisdom and royalty in cultures from Africa to Asia. They feature prominently in religious ceremonies, folklore and art. Historically, elephants were also used in warfare and labor. Both animals continue to influence human culture, reminding us of the deep connections between wildlife and human history. Adaptations Mammoths were well adapted to cold Ice Age environments with thick, shaggy fur and a dense layer of fat to keep warm. Their long and curved tusks helped them dig through snow to reach vegetation. They also had smaller ears compared to elephants, reducing heat loss. Elephants, on the other hand, are adapted to warmer climates. They have large ears that help dissipate heat and sparse hair to keep cool. Their trunks are highly versatile for feeding, drinking, and social interaction. Both species developed strong legs and tusks suited to their environments, showing how evolution shaped them for survival in different conditions.
