A pair of ornamental swans bought for a private pond in Montana in the 1960s eventually became the starting point for a very different kind of wildlife story. By the late 1970s, the flock in Paradise Valley had grown to 120, drawing the attention of Yellowstone National Park officials concerned about possible competition with native…
The method, called Extreme Event Aware, or “η-learning”, does not need previous extreme events to create these scenarios. (Representational AP photo) What would a once-in-a-century storm look like if it was stronger than anything recorded before? Researchers at the Massachusetts Institute of Technology (MIT) have developed a machine-learning method that can generate realistic scenarios for…
Representative Image (AI-generated) For humans to travel deeper into space and remain there for months or even years, they will need much more than powerful rockets. Astronauts must have a continuous supply of oxygen, water and food, while waste and carbon dioxide must be carefully managed. On short missions, these needs can largely be met…
A red fox introduced to California more than a century ago might seem far removed from the fate of a small marsh bird. Yet the two became linked in the coastal wetlands of Southern California, where the light-footed Ridgway’s rail has struggled to survive. The bird spends much of its time concealed among cordgrass and…
A combination of satellite images shows the valleys near the Nepal-China border on August 23, 2026, before the devastating floods and on August 26, 2026, after the disaster. (Photo: Reuters) Satellite images taken before and after the deadly flash flood near Nepal’s border with Tibet reveal a striking change in the landscape: stretches of green…
For years, the dense loops of repetitive DNA clustered near the middle of chromosomes were treated as evolutionary clutter. According to the new study published in Nature, titled ‘Meiotic pairing through barcode-like satellite DNA repeats‘, researchers working with fruit flies have shown that this so-called satellite DNA forms a kind of barcode: a unique combination…

NEW DELHI: Amid reports that three out of four people worldwide could face drought by 2050, the United Nations Convention to Combat Desertification (UNCCD) during its 17th conference (COP17) on Wednesday took…
Scientists have traced hidden pathways through animal evolution by comparing thousands of genomes and following pieces of chromosomes that have survived for hundreds of millions of years. The study examined 5,821 chromosome-scale genomes from 4,454 species across 19 animal phyla, using 29 ancient linkage groups as markers of chromosome history. Every one of the 406…
Deep inside a crystal cooled to nearly -230°C, MIT physicists have caught something rarely seen in quantum materials: two populations of electrons rebuilding themselves into wave-like order after being scattered apart by laser light, and doing so in two completely different ways. Working with erbium tritelluride, a rare-earth material known for hosting a pair of…
Researchers transporting Galvezia leucantha subsp. Leucantha at the restoration site, preparing for its planting A critically endangered shrub that once came close to disappearing from the Galápagos Islands is showing signs of a slow but important recovery after a careful conservation effort lasting nearly three decades. According to findings published in the journal Nature Conservation…
