Scientists at Scripps Institution of Oceanography at the University of California San Diego have discovered why some hybrids between populations of the same species don't develop as well as others. Th...
Differences in genetic and environmental variation in adult BMI by sex, age, time period, and region: an individual-based pooled analysis of 40 twin cohorts
BMI adults genetics twins international comparisons
2018/11/15
Background: Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m2)], but factors modifying these variance components are poorly understood.

Individual Vesicle Fusion Events Mediated by Lipid-anchored DNA
Cholesterol DNA Lipid Bilayers Phosphatidylcholines Phosphatidylethanolamines Membrane Fusion Unilamellar Liposomes
2016/5/25
Membrane fusion consists of a complex rearrangement of lipids and proteins that results in the merger of two lipid bilayers. We have developed a model system that employs synthetic DNA-lipid conjugate...
