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 ...

New biomarker to assess stem cells developed

A research team led by scientists from UCL have found a way to assess the viability of 'manufactured' stem cells known as induced pluripotent stem cells (iPSCs). Published today in Nature Communications, the team's discovery ...

How queen bees control the princesses

Queen bees and ants emit a chemical that alters the DNA of their daughters and keeps them as sterile and industrious workers, scientists have found.
