After decades of frozen diplomacy and political hostility, the United States and Cuba cautiously turned a page. Under US President Barack Obama, diplomatic ties were restored and the US Embassy in Havana reopened. On the Cuban side, the country was led by Raul Castro, who had taken over from his brother Fidel Castro. American diplomats, […]
Milky Way galaxy (Source: NASA) For decades, the search for extraterrestrial life has revolved around a simple rule: follow the water. If a distant planet has liquid water, and perhaps oxygen, it is flagged as potentially habitable. But new research led by scientists at ETH Zurich suggests that this long-standing strategy may be incomplete. A […]
For years, scientists studying earthquake risk in northwestern Turkey have known where the North Anatolian fault runs but not exactly how it behaves beneath the Marmara Sea. That uncertainty has mattered. The offshore section lies close to Istanbul and has not ruptured in a major earthquake for more than two centuries. A new study now […]
Do you think the white frozen sheets over Antarctica may hold a secret? This White, frozen, and solid Antarctica, although it looks quiet but beneath those endless plains of ice something enormous is going on. Scientists have revealed an entire hidden volcanic landscape buried under the continent. A China-led international research team has created the […]
How the Green River managed to cut straight through the already existing Uinta Mountains; scientists are surprised to know (Image Source – Wikipedia) The long-standing question of how the Green River cut through the Uinta Mountains has taken a step closer to resolution. New geological analysis suggests the answer lies not in the river alone, […]
Source: NASA Astrobiology Beginning two billion years of Earth’s history, the amount of oxygen was not sufficient, but rich in carbon dioxide and methane. The early forms have been able to generate metabolic energy from sunlight using the ‘purple’ pigment, predating the evolution of chlorophyll and photosynthesis. The pigment called retinal, if evolved, could absorb […]
Studies have reaffirmed a centuries-old theory, argued by many historians over time: there was, in fact, a Viking presence in America in the year 1021 AD. Scientific researchers, analysing historical reports from tree fossils at an archaeological site in Canada’s Newfoundland, have revealed that the Vikings arrived in the New World in a specific year: […]
Scientists in Antarctica have inaugurated the world’s first global repository of mountain ice cores, aiming to preserve vital records of Earth’s atmospheric history as glaciers rapidly melt due to global warming.The frozen sanctuary was opened on Wednesday at the Concordia research station on the Antarctic Plateau by the Ice Memory Foundation, a consortium of European […]
New Delhi: Scientists at the Institute of Nano Science and Technology (INST), Mohali, under the Department of Science and Technology (DST), have made a significant discovery. They have identified the semiconductor properties of a well-known self-assembling bacterial shell protein. This breakthrough could lead to the development of electronic devices that are safe, body-friendly, and environmentally […]
For a long time, the end of the Ice Age felt like a slow fading rather than a sharp break. Mammoths vanished. Old ways of living disappeared. The climate lurched colder again, without much warning. Archaeologists and geologists have argued over the cause for decades. Some blamed hunting. Others pointed to natural climate shifts. But […]
