Can Animals Detect Disasters Before They Strike? Nature's Early Warning Signs
Cows, sheep, and dogs in northern Italy were found to behave restlessly before earthquakes in a scientific study, especially those near the epicentre.
Toads may also sense quakes early. In 2009, common toads abandoned their breeding site days before a 6.3 magnitude quake in Italy, returning only after the seismic activity stopped.
Cats have shown odd behaviour like hiding or meowing excessively before quakes. Experts suggest they may detect subtle P-waves before the more destructive S-waves arrive.
Birds flew inland before the 2004 Indian Ocean tsunami. Their ability to sense low-frequency infrasonic waves could explain their early reaction.
Snakes have a long-documented history of fleeing before quakes. Ancient records from 373 BCE Greece and modern events in China show snakes escaping hibernation before tremors — possibly reacting to ground vibrations or magnetic changes.
Elephants are believed to detect infrasound — low-frequency vibrations — from miles away. During the 2004 tsunami, elephants in Thailand reportedly moved to higher ground before the waves arrived.

SpaceX delivers 4 astronauts to ISS just 15 hrs after launch
Washington: SpaceX delivered a fresh crew to the International Space Station on Saturday, making the trip in a quick 15 hours. The four US, Russian and Japanese astronauts pulled up in their SpaceX capsule after launching from NASA's Kennedy Space Centre. They will spend at least six months at the orbiting lab, swapping places with colleagues up there since March. SpaceX will bring those four back as early as Wednesday. Moving in are NASA's Zena Cardman and Mike Fincke, Japan's Kimiya Yui and Russia's Oleg Platonov — each of whom had been originally assigned to other missions. 'Hello, space station!' Fincke radioed as soon as the capsule docked high above the South Pacific. Cardman and another astronaut were pulled from a SpaceX flight last year to make room for NASA's two stuck astronauts, Boeing Starliner test pilots Butch Wilmore and Suni Williams, whose space station stay went from one week to more than nine months. Fincke and Yui had been training for the next Starliner mission. But with Starliner grounded by thruster and other problems until 2026, the two switched to SpaceX. Platonov was bumped from the Soyuz launch lineup a couple of years ago because of an undisclosed illness. Their arrival temporarily puts the space station population at 11. The astronauts greeting them had cold drinks and hot food waiting for them. While their taxi flight was speedy by US standards, the Russians hold the record for the fastest trip to the space station — a lightning-fast three hours.

Preserving the past: Ancient manuscripts in a race against time
1 2 3 4 5 6 Patna: Preservation of ancient manuscripts is an act of cultural reverence. Each brittle scroll and weathered folio is a portal to the past, where inked symbols became vessels of science, scripture and philosophy. But these treasures of knowledge, once passed hand to hand by sages and scribes, now face a race against time and nature. " Manuscripts are vulnerable to many threats – humidity, temperature shifts, exposure to light, chemical reactions – all of which accelerate their decay. And the act of handling them, no matter how gentle, only adds to their fragility," said a senior academic engaged in manuscript conservation. As the physical forms grow delicate, the mission to preserve what they hold becomes all the more urgent. Conservationists employ a mix of traditional and modern techniques – fumigation to repel infestations, controlled environments to manage temperature and humidity and increasingly, digitisation to ensure universal access. "Digital preservation allows these rare texts to reach anyone, anywhere," said a conservator involved in digitisation efforts. "Once online, a manuscript from 10th-century Mithila or ancient Nalanda becomes a resource for the world," he added. Yet, beyond methods lies the medium itself – the materials once used to create these manuscripts tell their own story of civilisational ingenuity. Jayadeo Mishra, former head of ancient Indian history and archaeology at Patna University, pointed to the world's earliest plant-based writing surface: papyrus, used in Egypt as far back as the third millennium BCE. "In India, palm leaves and tree bark were the principal writing supports before the introduction of paper in the 11th century," he said. These writing supports were as diverse as the ideas they carried: Tal-patra: Palm-leaf manuscripts strung like necklaces – bundles of 50 to 100 leaves, evenly cut and pressed between carved wooden covers. Some rare scrolls even span a metre in length, midribs intact, rolled like ancient carpets of thought. Bhoja-patra: Thin, crisp folios made from the bark of the Himalayan birch. They were sheathed between wooden boards or wrapped in cloth, holding centuries of poetry, law and devotion. Hansi-pata: Crafted from the bast fibre of the Agaru tree, these were slender, stackable folios rarely bound, often stored with reverence between wooden slats Handmade paper: Often folded into books or kept loose, these manuscripts mark the transition to more accessible formats, yet still retain a rustic elegance. Manufactured paper: As industrial methods took hold, folios on factory-made paper entered the scene. Some were bound; others remained loose, but each was a sign of evolving archival practices. One of the most evocative media, however, remains birch bark, the velvety, flexible skin of Himalayan birches. In ancient India, it was the parchment of choice for high knowledge. Mishra said, "Birch bark was used for Buddhist scriptures, classical Sanskrit texts, medical treatises and even scientific documents. These were living repositories of human understanding." Among the most famous birch bark texts is the Bower Manuscript, dating back to the 4th–6th century CE. It contains Ayurvedic medical knowledge, offering insights into early Indian treatments and formulations. Birch also hosted sections of the Mahabharata, Patanjali's grammar, and Buddhist canons such as the Dhammapada and Mahayana sutras. Even early astronomical charts and mathematical calculations found home on its soft, fibrous surface. Ashok Kumar Jha, physics teacher at Patna University and assistant director of the university's central library, said manuscript preservation was a delicate balance of traditional wisdom and modern science. "We often use natural deterrents like neem leaves, peacock feathers or even snake skin placed between the pages to prevent insect damage," he said. To guard against wind and humidity, manuscripts are stored in airtight wooden boxes, where bundles of herbs such as acorus and karpoora are tied in small pieces of cloth and tucked inside to maintain a controlled environment.
