Examining mRNA transcription difficulties
The corona pandemic has ensured that the term "mRNA" is now also known to a large public beyond laboratories and lecture halls. However, the molecule is much more than an important component of a successful vaccine against the SARS-CoV-2 virus. "mRNA.....»»
Missing link explains mRNA delivery in brain cells
Brain cells manufacture proteins in every corner, including their long branches. Neurons missing this ability cause severe neurological disorders like disability and epilepsy. The groups of Marino Zerial, Max Planck Institute (MPI) of Molecular Cell.....»»
Examining the developmental regulatory mechanism of limb loss in squamates
The development of limbs is significant for the origin and evolution of tetrapods, providing multiple functions and capabilities. Although limb loss has occurred in many clades to adapt to new environments, it is particularly common in Squamata, whic.....»»

Examining networks in the dog brain provides further insights into mammalian evolution
A study on canine brain networks reveals that during mammalian brain evolution, the role of the cingulate cortex, a bilateral structure located deep in the cerebral cortex, was partly taken over by the lateral frontal lobes, which control problem-sol.....»»
Examining the portrayal of climate change in history textbooks
California and Texas textbooks have their differences when it comes to teaching teenagers about American history and the way that subjects like race, gender, and immigration weave through it. But a new Stanford University study has found the two stat.....»»
Large-scale long terminal repeat insertions found to produce a significant set of novel transcripts in cotton
TEs (transposable elements), especially LTRs, are known to play an important role in determining the basic genome structure and influencing the expression of functional genes. Insertion of TE or LTR fragments may also create novel transcription start.....»»
How the epigenetic landscape modulates pioneer transcription factor binding
Like thread tightly wrapped around a spool, DNA is wrapped around histones and packaged into structures called nucleosomes. Scientists at St. Jude Children's Research Hospital are exploring how a type of transcription factor called a pioneer transcri.....»»
