A hurricane created a rare scientific opportunity: Scientists turned seven empty Bahamian islands into a living laboratory to watch lizard evolution unfold from the beginningA hurricane cleared Bahamian islands, offering scientists a rare chance to observe evolution beginning anew. Researchers introduced fourtee...
From farm ponds to AI chatbots: India's blueprint for revitalising dryland agriculture
Scientists found hidden gut bacterial populations linked to ageing, colorectal cancer and type 2 diabetes, and they can spread across continents within decadesRecent studies have uncovered unique genetic variations among common gut bacteria, revealing distinct populations that associate with aging...
Why are some people more curious, organised or compassionate than others? Huge genetic study uncovers over 1200 variants linked to personality while highlighting the power of environmentA large international genetics study has identified thousands of genetic variants linked to personality differences. These genetic influenc...
On a 12-day Russian biosatellite flight, seven silkworm varieties spun silk, built cocoons, mated and laid eggs; some developmental stages occurred 2-3 days faster than ground controlsChinese silkworms have successfully navigated their life cycle during an impressive twelve-day mission in space. Notably, their eggs hatche...
Tibetans adapted to live at high altitudes where oxygen is scarce; study suggests ancient interbreeding with an extinct human population may have given their ancestors a genetic advantage to survive in one of planet’s harshest environmentsTibetan highlander populations have distinct genetic variants in proximity to the EPAS1 gene, facilitating their adaptation to high altitud...
In 1995, Hurricane Luis damaged Maiden Island Reef in the Caribbean, already hit by development. Years later, Reef Balls supported 5,000 new coral colonies representing 30 speciesReef Balls are designed artificial reef modules mimicking natural structures. These concrete units provide habitat and shelter for marine s...
Are you born with your personality? Scientists have uncovered genetic clues to the traits that may shape who you becomeNew research reveals genetic variants influence personality traits like extraversion and conscientiousness. These genetic associations are ...
Quote of the day by Charles Darwin: 'A man’s friendships are one of the best measures of his...' - What this powerful insight reveals about character, trust and the kind of people we choose to surround ourselves with, and why our closest relationships may say more about us than we realizeCharles Darwin profoundly changed humanity's understanding of life on Earth. His voyage on the HMS Beagle provided crucial observations for...
Gujarat launches first state-level sports genomics programmeGujarat has launched a pioneering sports genomics programme for athletes. This initiative aims to understand genetic and physiological char...
In 2009, researchers acquired a laboratory colony of Aedes aegypti in Delhi and kept it without insecticide pressure. 17 years later, 10 micrograms killed 97.91% of females, yet survivors rapidly activated detoxification enzymesA Delhi study reveals mosquitoes surviving common insecticide treatments. This survival gap suggests a potential early warning of developin...
A dried lakebed in Africa's Chad sends 27.7 million tonnes of dust across 5,000 km of Atlantic Ocean each year, carrying phosphorus that helps sustain the Amazon rainforestThe Amazon rainforest has a surprising lifeline. Each year, about 27.7 million tonnes of Sahara dust travel nearly 5,000 kilometres from Ch...
Alaska Native genomes show selection signals potentially linked to life in the Arctic; researchers identified variants in pathways associated with high-latitude conditionsAlaskan Native genomes show adaptation signals potentially linked to cold environments. Researchers compared these signals with populations...
In the 1930s, just 9 to 20 foreign ant queens apparently stowed away on a ship; their descendants now infest more than 367 million U.S. acresA few fire ant queens arriving in Mobile, Alabama, in the 1930s established a widespread infestation. These invasive insects now infest ove...
In 2014, scientists compared EPAS1 DNA from 40 Tibetans and 40 Han Chinese and linked a high-altitude adaptation to Denisovan-like ancestry. 12 years later, the finding traced the genetic gift to an interbreeding event about 48,700 years agoIn 2014, scientists found a remarkable clue in Tibetan DNA. They compared the EPAS1 gene in 40 Tibetans and 40 Han Chinese and uncovered a ...
North America saved its bison from extinction. Now scientists face a new threatBison numbers have recovered after near extinction, but genetic diversity is now a concern. Fragmented herds lack natural gene exchange, po...
