Innovations through hair-thin optical fibres

Study shows what miniaturised optical filters make possible

22-Jan-2021

Scientists at the University of Bonn have built hair-thin optical fibre filters in a very simple way. They are not only extremely compact and stable, but also colour-tunable. This means they can be used in quantum technology and as sensors for temperature or for detecting atmospheric gases. The ...

Customized programming of human stem cells

The results open new possibilities in research

02-Dec-2020

Induced pluripotent stem cells (iPS) have the potential to convert into a wide variety of cell types and tissues. However, the "recipes" for this conversion are often complicated and difficult to implement. Researchers at the Center for Regenerative Therapies Dresden (CRTD) at TU Dresden, Harvard ...

New method allows precise gene control by light

Study enhances research toolbox with a new tool with great potential

02-Oct-2020

A novel optical switch makes it possible to precisely control the lifespan of genetic "copies". These are used by the cell as building instructions for the production of proteins. The method was developed by researchers from the universities of Bonn and Bayreuth. It may significantly advance the ...

How cells recognize uninvited guests

16-Apr-2020

Until now, the immune sensor TLR8 has remained in the shadows of science. A research team led by the University of Bonn has now discovered how this sensor plays an important role in defending human cells against intruders. The enzymes RNaseT2 and RNase2 cut ribonucleic acids (RNAs) of bacteria ...

New method identifies aggressive breast cancer

05-Nov-2019

Aggressive forms of breast cancer often manipulate the immune response in their favor. This manipulation is revealed in humans by the same immunological "signature" as in mice. This is shown by a study carried out by scientists from the University of Bonn together with Dutch colleagues. Their ...

Shipment tracking for "fat parcels" in the body

Researchers show that highly sensitive method can "track" lipid metabolism

16-Oct-2019

Without fat, nothing works in the body: These substances serve as energy suppliers and important building blocks - including for the envelopes of living cells. Numerous diseases are related to disorders in the fat metabolism, such as obesity or cancer. Researchers from the LIMES Institute at the ...

How Artificial Intelligence Detects Rare Diseases

11-Jun-2019

Every year, around half a million children worldwide are born with a rare hereditary disease. Obtaining a definitive diagnosis can be difficult and time consuming. In a study of 679 patients with 105 different rare diseases, scientists from the University of Bonn and the Charité - ...

In-depth insights into glass corrosion

Researchers observe the reaction of silicate glass with aqueous solutions in real time

04-Mar-2019

Silicate glass has many applications, including the use as a nuclear waste form to immobilize radioactive elements from spent fuel. However, it has one disadvantage - it corrodes when it comes into contact with aqueous solutions. Scientists at the University of Bonn were able to observe in detail ...

New mouse model makes stem cells light up green

Random find opens up new perspectives

06-Feb-2018

Multipotent stromal cells have long been a hot topic in medical research. Scientists at the University of Bonn have now found a way to specifically mark these stem cells. This makes it possible to analyze their distribution pattern and their function in living organisms. In order to examine a ...

Sorting machine for atoms

13-Feb-2017

Physicists at the University of Bonn have cleared a further hurdle on the path to creating quantum computers: in a recent study, they present a method with which they can very quickly and precisely sort large numbers of atoms. Imagine you are standing in a grocery store buying apple juice. ...
