Targeting gene expression in mitochondria

Novel strategy to investigate gene expression in mitochondria

25-Nov-2021

Mitochondria are considered the power plants of cells because they generate energy from our food with the help of oxygen. The machinery required for this is called the respiratory chain. Its central building blocks are formed by mitochondria themselves through the expression of genes of their own ...

“Tug of war” between cells – When crucial connections are missing

Research team investigates the importance of “tight junctions” for cell movement

15-Nov-2021

The ability of cells to move together in harmony is crucial for numerous biological processes in our body, for example wound healing, or the healthy development of an organism. This movement is made possible by the connections between individual cells. These connections, in turn, are established ...

‘Feeling’ the living cell’s life cycle using optical tweezers

Researchers use laser to reveal that the inside of living cells softens and fluidifies when dividing

26-Oct-2021

Living cells are the basic building blocks of all organisms. We, as humans, are essentially a collection of trillions of living cells: and all these cells emerge from a single fertilized egg. This means that “mitosis” (or cell division) is one of the most fundamental and important processes of ...

Eco-friendly plastic from cellulose and water

Researchers create new kind of environmentally friendly bioplastic with hydroplastic polymers

26-Jul-2021

Plastics offer many benefits to society and are widely used in our daily life: they are lightweight, cheap and adaptable. However, the production, processing and disposal of plastics are simply not sustainable, and pose a major global threat to the environment and human health. Eco-friendly ...

Fundamental regulation mechanism of proteins discovered

The chemical nature of the switch was completely unknown

11-May-2021

Proteins perform a vast array of functions in the cell of every living organism with critical roles in almost every biological process. Not only do they run our metabolism, manage cellular signaling and are in charge of energy production, as antibodies they are also the frontline workers of our ...

Crystal structures in super slow motion

Researchers first to succeed in filming a phase transition with extremely high spatial and temporal resolution

26-Jan-2021

Laser beams can be used to change the properties of materials in an extremely precise way. This principle is already widely used in technologies such as rewritable DVDs. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they ...

How the cell protects itself

Researchers discover the mechanism that prevents damage caused by shortened proteins

14-Jun-2019

The cell contains transcripts of the genetic material, which migrate from the cell nucleus to another part of the cell. This movement protects the genetic transcripts from the recruitment of “spliceosomes”. If this protection does not happen, the entire cell is in danger: meaning that cancer and ...

Stickier than expected: Hydrogen binds to graphene in 10 femtoseconds

07-May-2019

Graphene is celebrated as an extraordinary material. It consists of pure carbon, only a single atomic layer thick. Nevertheless, it is extremely stable, strong, and even conductive. For electronics, however, graphene still has crucial disadvantages. It cannot be used as a semiconductor, since it ...

Researchers combine light and X-ray microscopy for comprehensive insights

11-Sep-2018

Researchers at the University of Goettingen have used a novel microscopy method. In doing so they were able to show both the illuminated and the "dark side" of the cell. The team led by Prof. Dr. Tim Salditt and Prof. Dr. Sarah Köster from the Institute of X-Ray Physics "attached" small ...

German-French team of researchers discovers anti-aging in metallic glasses

05-Apr-2018

Metallic glasses and humans inhabit the same universe: they age. In time, their physical properties change towards a distinct direction. Researchers from the University of Göttingen and the European Synchrotron ESRF in Grenoble have now discovered a surprising effect in ultrastable metallic ...
