Why are genes less similar better for studying diseases?
Photo: Baboon, Clker-Free-Vector-Images, Pixabay Baboons show greater resilience to diseases despite their diverse genome, whereas humans, with a singular set of chromosomes, exhibit increased susceptibility – according to a new study published in ,,Cell Genomics”. Genetic variations differ in humans as a whole body or within the body in certain tissues. Genetic variation, simplifying, is the number of chromosomal…

What influences cognition? The exchange in purine bases and amino acids in the brain.
Photo: Adenine structure, one of the purine bases, specifically connects to thymine via hydrogen bonding in DNA and uracyl in RNA, as discovered by James Watson and Francis Crick in the 50s. Credit:kropekk_pl Of the about 20,000 metabolites discovered so far in human blood serum, over 1,300 and 140 lipids have been observed to profile the brain’s uptake and…

When and why might the genetic code change? Groundbreaking research addresses these questions.

Credit: Georgia Institute of Technology The specific chromosomal configurations and changes in their numbers may persist or disappear depending on population size and environmental conditions. Can we live outside…

Why does mitochondrial disruption cost so much?
Photo: Mitochondrium, SkieTheAce, Pixabay Does evolution know the paths of the past and future? That’s possible according to new research published in ,,Cell”. How? By tracking the transport of signals and nutrients inside a cell. The mitochondrion is a cell organelle with a separate from the cell nucleus genetic material inherited only from a female…

Why do women put on weight during pregnancy? Mouse example
Photo: Sunflower, Joshrowe, Pixabay Why do women gain more weight during pregnancy than the size of the fetus? Because of small intestine growth apart from the growing off-spring. Although pregnancy is a natural stage for females and generally does not require specific treatment if both the mother and child are healthy, the bodies of many…
