The multiple skeletal components of the skull originate asynchronously and their developmental schedule varies across amniotes. Here we present the embryonic ossification sequence of 134 species, ...
A study has traced thousands of conserved regulatory elements back 300 million years, revealing deep principles of plant genome evolution—a discovery that could pave the way for more precise ...
PHILADELPHIA—Brain development does not occur uniformly across the brain, but follows a newly identified developmental sequence, according to a new Penn Medicine study. Brain regions that support ...
The sculpting of neuronal connections during brain development depends on a precise balance between inhibition and excitation — an excess of GABA (γ-aminobutyric acid)-mediated inhibition might ...
The brain is known to develop gradually throughout the human lifespan, following a hierarchical pattern. First, it adapts to support basic functions, such as movement and sensory perception, then it ...
More than 2.3 million ancient genetic switches discovered in plants reveal how key growth controls endured 300 million years ...
SCARs were developed by cloning RAPDPCR amplicons into commercially available vectors, sequencing them and designing specific primers for PCR, direct sequencing and phylogenetic analysis. Eighteen to ...
