What is a virgin birth? Graphic shows how female stingray got pregnant
Certain animals are capable of reproducing through parthenogenesis, or 'virgin birth', without mating with a male.
Facultative parthenogenesis is a process where the offspring receives its full set of genes from the mother, with fertilization occurring by a cell taken from the mother herself. [ more ]
Why Do I Keep Getting COVID-19 But Those Around Me Don't?
Environmental factors such as social distancing and vaccination played a bigger role in COVID-19 infection at the start of the pandemic, while genetics became more important over time.
Genetics now account for 30% to 70% of a person's chance of getting COVID-19. [ more ]
The twins who show why some people are more likely to gain weight
Researchers from Finland have found a new approach to understanding why some people are more susceptible to weight gain than others.
The study followed the BMI trajectory of twins with significant weight differences, and found that environmental factors may play a role in weight gain.
This research opens doors to discovering the factors that protect or predispose people to weight gain and maintaining a healthy weight. [ more ]

Is Bisexuality Genetic? It's More Complex Than Some Studies Imply
A recent study suggests a genetic link between bisexuality in men and risk-taking behavior.
The study found that certain gene variants associated with bisexuality were also associated with a higher number of sexual partners and a propensity for risk-taking. [ more ]
Syphilislike Diseases Have Plagued Humans for 14,000 Years
Oldest evidence of syphilis-causing microorganisms found in remains of people on the eastern coast of South America 2,000 years ago.
Discovery challenges the theory that Columbus's crew brought syphilis to Europe and pushes back the origins of syphilis by thousands of years. [ more ]
Ancient DNA Reveals Origins of Multiple Sclerosis in Europe
Migrants who arrived in Europe in three waves starting 45,000 years ago brought with them genetic traits found in modern Europeans, including a heightened risk for multiple sclerosis.
The regional variation in certain traits found in modern Europeans was caused by differences in migrants' dispersal patterns, contradicting the idea that genetic differences arose mainly as people adapted to specific locations in Europe. [ more ]
Origin of Multiple Sclerosis And These Common Diseases Lies in Ancient DNA
The Yamnaya migration 5,000 years ago introduced genes conferring risk for multiple sclerosis (MS) into Europe.
