Genes develop on their own, on their own timeline. That means that someone could be a child prodigy if everything comes together early on, but genius might not emerge until later in life -- and it can even wane. This is where genetics and environment collide. While we might be able to...

This study combines lipidomic and transcriptomic analyses to show that macrophage-derived foam cells are associated with suppression, rather than activation, of inflammatory genes and that most of the changes in gene expression and lipid metabolism are triggered by the accumulation of desmosterol, an ...
A major question is why are there only two types of gametes (sperm- and egg cells), two types of sex steroids, (androgens and estrogens in vertebrates, and two types of ecdysteroids in insects), while the reproduction-related behaviour of the gamete producers displays a much greater ...
In an attempt to identify genes that are involved in Drosophila embryonic cardiac development, we have cloned and characterized a gene whose function is required late in embryogenesis to control heart rate and muscular activity. This gene has been named held out wings (how) because hypomorphic muta...
DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic origins of which have been investigated for many...
"Scientists have hypothesized for 100 years that inversions are important for the evolution of some of the complex behaviors that we see in nature," Maney says. "But inversions are challenging to understand because, when they turn into supergenes, all of the genes are inherited together. We al...
Less well known is a reclusive young woman from Massachusetts named Emily Dickinson. She and Walt Whitman are considered the greatest American poets of the 19th Century. Jane Austen’s genius was for understanding human ...
Once aware of the broader picture regarding the role of brain flexibility, we should primarily speak of neuroplasticity as a balance between what we have named “upward” and “downward” neuroplasticity. Just common binary words to describe each path in which neuroplasticity could move along a dir...
