Microscopy technique enables 3D super-resolution nanometre-scale imaging

Research team combine two techniques to achieve isotropic super-resolution imaging

24-Jun-2022

Over the last two decades, microscopy has seen unprecedented advances in speed and resolution. However, cellular structures are essentially three-dimensional, and conventional super-resolution techniques often lack the necessary resolution in all three directions to capture details at a nanometer ...

Sharp X-ray images despite imperfect lenses

New method for X-ray microscopy

03-Jun-2022

X-rays make it possible to explore inside human bodies or peer inside objects. The technology used to illuminating the detail in microscopically small structures is the same as that used in familiar situations – such as medical imaging at a clinic or luggage control at the airport. X-ray ...

Covid-19 can cause vascular damage to the heart

Team uses innovative X-ray imaging at DESY to provide proof for the first time

24-Dec-2021

Using DESY's X-ray lightsource PETRA III, an interdisciplinary research team led by the University of Göttingen and Hannover Medical School (MHH) has detected significant changes in the heart muscle tissue of people who died from Covid-19. Damage to lung tissue has been the research focus in this ...

‘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 ...

Researchers Find Warning Signs for Dementia in the Blood

Levels of Certain microRNAs Indicate Risk for Cognitive Decline

14-Oct-2021

Researchers at the DZNE and the University Medical Center Göttingen (UMG) have identified molecules in the blood that can indicate impending dementia. Their findings, which are presented in the scientific journal “EMBO Molecular Medicine”, are based on human studies and laboratory experiments. ...

High-resolution microscope built from LEGO and bits of phone

Research shows constructing microscope improves children’s understanding - enlightening, educational and fun

06-Jul-2021

Microscopy is an essential tool in many fields of science and medicine. However, many groups have limited access to this technology due to its cost and fragility. Now, researchers from the Universities of Göttingen and Münster have succeeded in building a high-resolution microscope using nothing ...

Clever biomolecular labelling enables identification of immune cells

New strategy for labelling peptides

09-Jun-2021

Biomolecules regulate the biological functions inside every living cell. If scientists can understand the molecular mechanisms of such functions, then it is possible to detect severe dysfunction which can lead to illness. At a molecular level, this can be achieved with fluorescent markers that ...

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 nitrogen is transferred by a catalyst

The detailed understanding will allow for the design of catalysts tailored for specific reactions

16-Nov-2020

Catalysts with a metal-nitrogen bond can transfer nitrogen to organic molecules. In this process short-lived molecular species are formed, whose properties critically determine the course of the reaction and product formation. The key compound in a catalytic nitrogen-atom transfer reaction has ...
