Pinpoint creation of chirality by organic catalysts

Researchers at Nagoya University have reported in Nature Communications on the development of an organic catalyst (organocatalyst) that triggers a highly stereoselective 1,6-addition of azlactones (nucleophile) to a δ-aryl ...

What happens in the cell nucleus after fertilization

A team of scientists at the Helmholtz Zentrum München shows changes in the immediate environment of DNA after the ovum and sperm fuse to form the zygote. The results suggest why all conceivable somatic cells can develop ...

DNA methylation affects superiority of hybrid plants

Hybrid vigor refers to when a crossbreed plant or animal shows superior traits compared to its parents. A research group has discovered that a gene involved in maintaining DNA methylation is closely connected to hybrid vigor ...

Epigenetic repression suppresses genomic instability

Susan Gasser and her group at the FMI have found the pathway through which eukaryotic organisms protect their genomes from rearrangements and deletions that arise from repetitive DNA. Human genomes, like those of simple animals ...

Tags on RNA silence X chromosome in females

The addition of a chemical tag on an RNA molecule is the critical switch that inactivates one X chromosome in every cell, ensuring healthy development in all female mammals, according to new research by Weill Cornell Medicine ...

New hydrogel bandage for burns less painful to remove

(Phys.org)—A combined team of researchers from Boston University and Beth Israel Deaconess Medical Center, also in Boston, has published a paper in the journal Angewandte Chemie describing a new type of hydrogel they have ...
