Every year, the southwest monsoon event changes India’s river systems. The changes include turning one of India’s rivers red. The effect is associated with increased rainfall. The changing colours of India’s rivers are closely linked with the monsoon. The monsoon is associated with changes in India’s climate. The changes in India’s rivers are linked with…
The cave is low and dark, and it is dug into limestone on a little island in the Baltic Sea where the wind blows salt from all directions. For thousands of years, humans used this spot to be safe while they hunted seals and fished in the ocean. The trash they left behind was normal….
A world in warming, under most circumstances, tipping toward deep cooling does seem counterintuitive; yet, Earth’s geological record is replete with such episodes when rising greenhouse gases were followed by abrupt climatic reversals. Today, scientists increasingly look to the oceans for an explanation, where the quiet work of microscopic organisms regulates the exchange of carbon…
Most of the time, people never question the colour of water. It feels invisible in a glass, like air you can drink. Then a holiday comes around, someone stands by the sea, and suddenly the water looks blue or green or something in between. It’s the same substance, yet it behaves differently depending on how…
The Red Sea is a narrow stretch of water that runs southeast from Suez in Egypt for about 1,200 miles (1,930 km) all the way to the Bab el-Mandeb Strait, which links it to the Gulf of Aden and then the Arabian Sea. It separates the coasts of Egypt, Sudan, and Eritrea on the west…
While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more subtle manner. Instead of moving people or objects through history, researchers are investigating whether it is possible to reverse physical processes themselves. Recent advances in wave physics hint that, under the right conditions, time can…
The spirit of Christmas is here, gifts and wishes are pouring in, and the joy of the holidays has taken over. Amid the choirs and carols of the holiday, Nasa shared its celestial greetings, celebrating the day.The cosmic tree from the nebula group NGC 2264, formed with a cluster of stars emitting blue and white…
As NASA plans for long-term human missions beyond Earth, one question keeps resurfacing: how do you sustain life in places where resupply from Earth is slow, expensive, and limited? Machines and technology will play a significant role, but scientists are increasingly turning to biology for answers. In recent research, insects have emerged as unlikely but…
Mosquitoes target people who release more carbon dioxide, body heat and skin chemicals that signal an easy blood meal/ Representative Image If you have ever stood outside with friends and watched mosquitoes ignore everyone else while repeatedly landing on you, the experience can feel personal. Scientists say it is not. According to decades of entomology…
It does not look like a breakthrough at first. Just the faint outline of a foot, pressed into what was once soft ground and later hardened by time. No bones nearby. No tools neatly arranged. And yet this single footprint, found in southern Chile, may be one of the most important human traces ever uncovered…
While the term new moon is well established in astronomy, the phrase black moon is far more informal, yet it has gained steady popularity among skywatchers and space enthusiasts. A black moon does not describe a visible event in the night sky. Instead, it refers to a rare timing quirk in the lunar calendar. Much…
Earth’s relationship with space is much more complex than it used to be. Space around our planet was thought to be influenced almost solely by natural forces like the Sun and the Earth’s magnetic field for many years. But the latest studies indicate that humans have had a hand in the matter too, although it…
Artificial intelligence has already taken over large parts of modern hiring. Algorithms scan CVs, software ranks candidates, and automated systems now replace junior recruiters and even some of the engineers who once built them. CV screening, shortlisting and candidate ranking are now routinely automated. What has largely remained untouched, until now, is the interview: a…
India’s scientific milestones of 2025 We Indians take immense pride in a relationship with science that is deeply emotional. It is visible when millions watch a rocket rise from Sriharikota, when collective celebration follows a successful mission, or when our eyes well up as disappointment settles after years of painstaking work do not go as…
Scientists were stunned as dolphins used suction feeding, flaring lips and throats to vacuum prey whole/ AI illustration For most people, dolphins sit in a safe mental category: intelligent, playful, sociable animals better known for aquarium tricks and beachside encounters than for anything genuinely threatening. They do not carry the menace of sharks or the…
NASA confirmed that a bus-sized asteroid passed Earth on 22 December 2025 in a routine flyby that had been tracked well in advance and posed no risk to the planet. The object had been monitored by astronomers for some time, and its movement was carefully calculated long before it approached Earth. According to NASA, the…
A piece of space debris is the focus of the closest attention of astronomers worldwide as scientists evaluate a rare, but very dramatic, option. A collision of asteroid 2024 YR4, approximately 60 metres long, with the Moon in December 2032 could result in an impact visible from Earth due to the enormous force. Researchers, however,…
US President Donald Trump has revealed a far-reaching new executive order outlining America’s priorities in space for the remainder of the decade. The directive lays out ambitious targets ranging from returning humans to the Moon to expanding missile defence systems in orbit and accelerating the growth of a commercial space economy. Ultimately, the plan is…
Historically, many scientists and society have been fascinated by the prospect of making contact with extraterrestrial civilisations. People around the world have wished for the day we discover an advanced race living on another planet and eventually reach out to us. Many accepted assumptions about when we will discover and how we would receive transmissions…
These shrimp, in huge colonies, snap their claws, creating a racket that can touch 210 decibels. Scientists say this can be louder than ship engines. AI image When asked which is the loudest animal in the ocean, most people would guess it’s a whale — maybe a sperm whale which clicks at an ear-rattling 230…
