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 ...

Ancient Migration Shaped Yemen's Unique Genetic Makeup, Finds New Study
A detailed genetic analysis of Yemen has uncovered the region's complex migration history. By studying 46 Yemeni genomes, the research reveals significant genetic influences from East Africa, the Levant, and Arabia. Maternal DNA shows a marked African presence, with one-third of individuals carrying African-specific mitochondrial haplogroups, parti...

Study Reveals Genetic and Linguistic Roots of Indo-European Populations
A comprehensive study involving 91 researchers provides significant insights into the genetic and linguistic origins of Indo-European populations. It identifies two main migrations during the Bronze Age, with steppe ancestry spreading across Europe. The research also links specific populations like the Spanish, French, and Italian to Bell Beaker an...

Genetic Analysis Reveals Family Sacrifices in 1,500-Year-Old Moche Tomb in Peru
A genetic study of a 1,500-year-old Moche tomb in Peru has revealed a unique sacrificial ritual involving family members. Two teenagers, one a boy sacrificed to his father and a girl to her aunt, were found buried alongside high-status individuals in a tomb at the Huaca Cao Viejo temple. This discovery, reported in PNAS, challenges previous assumpt...

Tiny Worms Living In Chernobyl Can Offer DNA Repair Mechanism For Humans: Study
These worms, called nematodes, have simple genomes and a short lifespan, which enabled researchers to study their multiple generations.

17,000-Year-Old DNA of Ice Age Infant Reveals Dark Skin, Blue Eyes
Analysis of a 17,000-year-old infant’s remains from southern Italy sheds light on Ice Age ancestry and health. The infant, found in a Puglian cave, was likely around a year old at death and had distinctive traits—brown skin, blue eyes, and curly dark hair. His genome links him to Europe’s Villabruna lineage, suggesting their presence in south...

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...

Can your Blood Type Affect Your Stroke Risk? Here's What You Need to Know
Recent research indicates that individuals with type A blood are more likely to suffer a stroke before the age of 60 compared to those with other blood types. A 2022 study involving nearly 17,000 stroke patients and 600,000 controls found a 16% increased risk for those with variations of the A blood group. The findings suggest that the mechanisms b...

Ancient Viral Genomes in Glaciers Reveal Pathogens’ Climate Adaptation Over 41,000 Years
Researchers from The Ohio State University have uncovered how ancient viruses preserved in glacier ice have adapted to Earth's shifting climate over the past 41,000 years. By analysing viral genomes from the Guliya Glacier on the Tibetan Plateau, the study reveals significant variations in viral communities between cold and warm climatic periods. T...

10-Year Long Study Reveals New "Tree Of Life" For All Birds Living Today
The largest-ever study of bird genomes has produced a remarkably clear picture of the bird family tree. Published in the journal Nature today, our study shows that most of the modern groups of birds first appeared within 5 million years after the ext

New Study Reveals How Much Neanderthal DNA Still Exists In Modern Humans
Recent scientific findings have revealed that Neanderthal genes compose 1 to 4 per cent of the genome of modern-day humans whose ancestors moved out of Africa.

IIT Delhi Study Reveals Mechanisms Driving SARS-CoV-2 Evolution In Humans
According to the seven-member research team, CpG (a cytosine followed by a guanine) numbers in virus genomes have been linked to host-switching, the efficiency of virus replication, immune evasion and the ability of a virus to cause disease.

Genome Study Provides Important Insight on Endangered Vaquita Native to Mexico's Gulf of California
Genetic Assessment has provided new hope to save small tropical porpoise native to Mexico's Gulf of California with its population dwindling to about 10. Computational simulations performed by the researchers to predict extinction risk showed that vaquitas have a high chance of rebounding if fishing gillnets are completely eliminated from their hab...
