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 ...

Two proteins safeguard skin stem cells

Our skin renews, heals wounds, and regenerates the hair that covers it thanks to a small group of stem cells. These cells continually produce new ones, which appear on the skin surface after a few days. A study led by ICREA ...

Plants remember stress to help protect themselves

A new generation of plants better adapted to mitigate the effects of environmental change could be created following a fundamental step towards understanding how plants are able to retain a memory of stress exposure.

Getting the most out of natural gas

ETH scientists have discovered a new catalyst that allows the easy conversion of natural gas constituents into precursors for the production of fuels or complex chemicals, such as polymers or pharmaceuticals. The new catalyst ...

DNA molecules directly interact with each other based on sequence

Proteins play a large role in DNA regulation, but a new study finds that DNA molecules directly interact with one another in a way that's dependent on the sequence of the DNA and epigenetic factors. This could have implications ...
