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...

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...

Understanding Blood Types: Rare Groups Beyond ABO and Rh Factor Explained
Blood types, classified by antigens on red blood cells, extend beyond the ABO and Rh systems. According to experts, over 47 recognised blood group systems exist, with more discoveries emerging. Rare types, such as the Bombay phenotype, require precise matches during transfusions, particularly for patients with certain genetic conditions. Maintainin...

Pompeii DNA Study Reveals Surprising Ancestry and Uncovers New Insights on Family and Gender Assumptions
Recent DNA findings from Pompeii reveal complex ancestry and social diversity, challenging earlier assumptions about family structures and cultural roles in the ancient city. Analysing skeletal remains has shown that some groups presumed to be family members were not biologically related, while traditional gender roles were also re-evaluated. This ...

Understanding Twins: Types, Facts, and the Unique Bonds They Share
Twins are a captivating subject of study, with two main types: identical and fraternal. Identical twins result from a single fertilised egg splitting, sharing identical DNA. Fraternal twins develop from separate eggs fertilised simultaneously. Their emotional connection often surpasses typical sibling relationships, leading to intriguing dynamics. ...

Panda-Coloured Amphipod Confirmed as New Species, Discovered Along Japan’s Coastline
A newly discovered amphipod species, Melita panda, has been confirmed as a unique species in Japan’s coastal waters. This crustacean, named for its black-and-white coloring resembling that of a panda, was originally found in the 1990s but has only now been recognized as a distinct species. Researchers at Hiroshima University conducted thorough ge...

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...

How Rainwater Helped Stabilise Early Cells, Enabling Life's Complexity on Earth
Recent research led by Aman Agrawal, in collaboration with experts from the University of Chicago and University of Houston, uncovers the potential role rainwater played in stabilising protocells on early Earth. Their findings show how this helped prevent RNA leakage and uncontrolled mixing, allowing the formation of stable genetic material. This n...

Banana Apocalypse Could Be Averted Thanks to Genetic Breakthrough
A recent breakthrough in genetic research offers new hope for saving the world’s banana supply from fusarium wilt, a devastating disease that threatens the Cavendish variety. This study, detailed in Nature Microbiology, sheds light on how this disease, which previously wiped out the Gros Michel bananas in the 1950s, is now affecting Cavendish ban...

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...
