A 120-year-old taxidermy bear is helping scientists solve modern wildlife crimes; its preserved hair could change how poaching cases are investigatedA museum bear named Boris is now helping fight wildlife crime. His fur is being studied for microscopic and genetic characteristics. This r...- 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...
- A 31,000-year-old fossil has challenged everything scientists thought about the extinct 'American cheetah' — its DNA and diet tell a surprising storyAncient DNA studies have rewritten the family tree of the "American cheetah," Miracinonyx trumani. Genetic evidence shows this extinct cat ...
- The Pompeii of Madhya Pradesh: Unlocking the secrets of Ujjain's 42 skeletonsForty-two skeletons discovered at Kumhar Tekri in Ujjain remain an archaeological mystery. These ancient remains were found in diverse posi...
- Scientists find California blackworms have an unexpected advantage in tight spaces: The worms escape narrow channels faster than wider ones, a finding that could influence the design of soft robotsCalifornia blackworms have been observed skillfully traversing narrow channels, showing superior navigation compared to wider ones. The con...
- 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...
- Life on Earth has always used four DNA letters, but scientists have created a bigger genetic alphabet and found something unexpectedScientists have demonstrated RNA polymerase can read eight genetic letters. This enzyme accurately transcribes synthetic DNA, which nature ...
- Something strange may be happening high above the surface of Venus: New study finds a surprising clue about whether life could survive in its acidic cloudsNew research suggests peptides can survive Venus's acidic clouds. These molecules maintain stable structures in highly concentrated sulfuri...
- In 1984, NASA left Bacillus spores in space for nearly 6 years; after LDEF returned to Earth, 1–2% of the exposed spores were still aliveDuring an extensive six-year voyage aboard the LDEF satellite, soil bacteria spores demonstrated remarkable resilience, surviving the rigor...
- In 2015, Japan exposed bacteria outside the ISS for 3 years; some clumps survived, while thicker ones were estimated to last longerJapanese researchers launched the resilient bacteria Deinococcus into orbit aboard the International Space Station. Remarkably, these micro...
- In 2007, ESA sent 3,000 tardigrades into low Earth orbit; after 10 days of vacuum and UV-A/UV-B exposure, 68% revived upon rehydrationKnown for their resilience, tardigrades have astonishingly withstood the harsh conditions of outer space. Their unique protein showcases an...
- In 1992, NASA studied C. elegans worms exposed to space radiation on IML-1; the experiment reported higher mutation rates than in ground controlsIn 1992, micro worms unveiled the troubling effects of space radiation on DNA, showcasing considerable genetic harm to these minuscule crea...
- 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 ...
- In 2024, Florida scientists found a hidden trail left behind by invasive snakes — their DNA can linger in water and soil even after they disappearA 2024 study by Florida scientists found that invasive snakes can be detected through traces of DNA left behind in water and soil. The new ...
- Science says ancient soil can reveal about extinct animals that left no bones, the hidden DNA record beneath our feetThe discovery of DNA preserved in ancient sediments is expanding our understanding of what can constitute a fossil record. Bones provide ph...
- 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...
- In 2010, NASA launched a 12-pound, loaf-of-bread-sized satellite with two Bacillus populations; radiation exposure reached about 15 times that of the ISS orbitNASA's O/OREOS mission embarked on an exciting journey to observe how bacteria withstand the rigors of space radiation. The compact satelli...
- Not an animal, but one popular fruit shares 60% of human genes. Genetic expert says it’s not shocking: ‘There’s a lot of things we do the same way…'Who doesn’t like to munch on a banana or two during the summer? Although a guilty pleasure for those with high blood sugar levels, it remai...
- A 2024 Harvard-led study collected 281 German cockroaches from 17 countries across 6 continents and analyzed their DNA; researchers found the pest evolved from an Asian cockroach about 2,100 years ago before hitching rides with humans around the worldAccording to new genetic findings, the German cockroach's roots trace back to Asia nearly 2,000 years ago. It seems that the cockroach adap...
- In 2000, University Of Illinois researchers searched 1,000 trillion DNA molecules for lead-sensitive DNA. 9 years later, their lab reported DNA sensors with sensitivity as low as 11 parts per trillion for toxic metals in drinking waterLead detection may soon look very different from a trip to the laboratory. Researchers at the University of Illinois developed a DNA lead s...
