Genetic Mutations May Directly Influence Epigenetic Clocks and Aging
A study published in Nature Aging suggests a direct link between genetic mutations and epigenetic clocks, reshaping current theories on biological aging. Researchers found that DNA mutations influence methylation patterns, potentially driving the aging process. This challenges the idea that epigenetic changes are merely reflections of aging rather ...

Lake Mendota's Bacteria Are Stuck in an Evolutionary Loop, Finds Study
Research in Lake Mendota reveals seasonal bacterial evolution, with microbes adapting to environmental shifts over 20 years. Despite rapid changes, many species return to prior genetic states, highlighting cyclical evolution patterns. Extreme weather events, like those seen in 2012, led to lasting genetic adaptations, offering insights into how mic...

Fruit Fly Experiment on Tiangong Space Station Explores Effects of Microgravity
Chinese astronauts are studying fruit flies aboard the Tiangong space station to understand how microgravity and sub-magnetic fields affect living organisms. The research focuses on biological rhythms, molecular mechanisms, and movement patterns, with samples set to return to Earth for detailed analysis. The study could provide valuable insights fo...

World’s Largest Living Organism Pando Might Be The Oldest Living Thing, Reveals New Study
Pando, a massive quaking aspen spanning 100 acres in Utah, is estimated to be between 16,000 and 80,000 years old. Research suggests that Pando has witnessed and survived vast environmental changes since humans began migrating out of Africa. The genetically linked stems span an interconnected root system that highlights plant resilience. Challenges...

Scientists Unravel Rose Genetics: How Eastern and Western Species Created Modern Varieties
A recent study uncovers the genetic origins of modern roses, showing how Eastern and Western species combined to create the roses we know today. Led by Professor Zhangjun Fei at the Boyce Thompson Institute, researchers mapped the genome of the modern rose variety ‘Samantha®’ and sequenced 233 other rose varieties. The study sheds light on bre...

Woolly Mammoth Comeback? Science Might Revive Extinct Species by 2028
The ambitious field of de-extinction is inching closer to reality with companies like Colossal Biosciences leading the charge. The company aims to revive extinct species such as the woolly mammoth by 2028. Their method involves transferring mammoth genes, which encode traits like shaggy fur and curved tusks, into the DNA of Asian elephants. Despite...

Last Woolly Mammoths Extinction Mystery: New Genetic Insights Revealed
Four thousand years ago, the last woolly mammoths lived on Wrangel Island, situated off the coast of present-day Siberia. Traditionally, it was believed that their remote location led to inbreeding, which was thought to be the primary cause of their extinction. However, recent research challenges this notion. A study reveals new insights into the m...

Rapid Monkeypox Spread Driven By Mutations? What WHO Says
Studies are under way to see whether genetic changes in the monkeypox virus are driving the rapid spread of the disease, the World Health Organization told AFP on Wednesday.

Genetic Evidence of Typhoid and Plague Causing Pathogens Found in DNA of Ancient Civilisations
Scientists had attributed the fall of several ancient civilizations including the Akkadian Empire, the Old Kingdom of Egypt, to factors like climate change and shifting allegiances. However, a new study proposes that this could be due to some extinct pathogens.

Scientists Discover Unique Group of Polar Bears Relying on Glacial Ice in Southeast Greenland
Scientists have discovered a unique group of polar bears with distinct behaviour in southeast Greenland, that have remained isolated for hundreds of years. These polar bears are genetically different from other polar bears. While polar bears in the Arctic region usually depend on sea ice to hunt seals, the new group of polar bears appears to have ...

Evolution Might be Happening 4 Times Faster Than What Charles Darwin Had Predicted: Study
A new research suggests that the Darwinian evolution could be happening up to four times faster than previously thought. Based on an analysis of genetic variation, the researchers state evolution can happen faster if there are more genetic differences in a species. This is because certain traits die off and stronger ones get established. The study ...

US Confirms Wuhan Virus Sequences Were Removed From Database
Details of the genetic makeup of some of the earliest samples of coronavirus in China were removed from an American database where they were initially stored at the request of Chinese researchers, U.S. officials confirmed.
