Genomic Analysis Of 10,000 Indians Likely To Kickstart Precision Medicine
The GenomeIndia Project -- India's reference dataset for genetics and genomics -- could help improve how disease is diagnosed, predict one's response to a drug and kick-start precision medicine efforts in India, according to a research article.

Iguanas Travelled 5,000 Miles to Fiji on Rafts 34 Million Years Ago
Iguanas undertook a remarkable 5,000-mile journey from North America to Fiji around 34 million years ago. According to a new genetic study, these reptiles floated on rafts of vegetation, possibly due to extreme weather events. The research, published in PNAS, found that Fiji’s iguanas are closely related to North American species, contradicting e...

Ancient Europeans Retained Dark Skin, Hair and Eyes Until the Iron Age, Claims New Study
A genetic study analysing 348 ancient DNA samples reveals that most prehistoric Europeans had dark skin, hair, and eyes well into the Iron Age. Although genes for lighter pigmentation appeared around 14,000 years ago, they remained rare until about 3,000 years ago. Lighter skin may have been advantageous for vitamin D production, while lighter eyes...

Neanderthal Genetic Bottleneck 110,000 Years Ago May Explain Their Decline
A study suggests that Neanderthals experienced a population bottleneck 110,000 years ago, drastically reducing their genetic diversity. CT scans of their inner ear bones revealed a sharp decline in variation, indicating a drop in population size. This event may have made Neanderthals more vulnerable to environmental and competitive pressures, contr...

Ancient DNA Sheds Light on the Diverse Genetic Origins of the European Huns
A new study has analysed ancient DNA from 370 individuals buried between the fourth and sixth centuries, revealing that the European Huns were genetically diverse. While some showed direct ties to Xiongnu elites from Mongolia, most carried mixed Northeast Asian ancestry. Researchers found no evidence of a single large-scale migration but instead ob...

AI-Powered Evo-2 Model Generates DNA, Advances Genome Research
Evo-2, an AI model developed by the Arc Institute, Stanford University, and NVIDIA, has been trained on 128,000 genomes, enabling it to generate DNA sequences and predict mutations. It analyses both coding and non-coding DNA, helping researchers understand gene functions and diseases. The model has already demonstrated capabilities in designing CRI...

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 ...

Bacteria-Based Cellulose Bandage Speeds Up Plant Healing and Growth
A bacteria-based cellulose bandage has been found to enhance plant healing and regeneration. Studies show that wounds treated with these patches heal faster, with over 80 percent recovery in a week compared to less than 20 percent in untreated plants. The cellulose also speeds up root and leaf development in plant cuttings. Researchers attribute th...

Study Reveals Surprising Factor Behind Gout - It's Not What You Think
A groundbreaking study reveals that genetics play a much larger role in causing gout than lifestyle factors.

How To Reproduce With Two Fathers - And No Biological Mother
At the International Summit on Human Genome Editing, held in March 2023 at the Francis Crick Institute in London, Japanese researcher Katsuhiko Hayashi stunned attendees when he explained how he had successfully reproduced mice from two male parents.

Mysterious Brain Disease Found in Dead Great White Sharks Along Atlantic Coast
A series of unexplained great white shark deaths along the North American Atlantic Coast has sparked scientific investigations. The first case, recorded in August 2023, revealed brain inflammation in a shark found in Prince Edward Island. Further cases showed similar patterns, with experts struggling to determine the cause. Some scientists suggest ...

In Major Breakthrough, Mice Created With Two Fathers And No Mother Reach Adulthood
By using embryonic stem cell engineering, the researchers were able to reprogram the imprinted genes, effectively allowing the mice to develop with genetic material from two fathers.

First Mouse with Two Fathers Thrives into Adulthood, Marking New Scientific Milestone
Scientists have achieved a major milestone by creating a bi-paternal mouse, marking progress in stem cell science and reproductive biology. By modifying imprinting genes, researchers overcame previous barriers to unisexual mammalian reproduction. While only a small percentage of the engineered embryos survived to birth, the research demonstrates th...

Neanderthal Blood Protein Incompatibilities May Have Contributed to Extinction
Research indicates that genetic differences in Neanderthal blood proteins may have played a role in their extinction. Scientists discovered that Neanderthals had a rare RhD blood type, which was incompatible with the blood types of Denisovans and Homo sapiens. This incompatibility could have led to hemolytic disease in mixed-species offspring, resu...

Human Outer Ears May Have Evolved from Ancient Fish Gills, Study Finds
Human outer ears may have evolved from the cartilage in ancient fish gills, according to recent research. Gene-editing experiments demonstrated a genetic link between fish gills and mammalian ears, with findings suggesting this transformation dates back millions of years. Researchers tested genetic enhancers in zebrafish, mice, and lizards, uncover...
