Histology in 3D

New staining method enables Nano-CT imaging of tissue samples

26-Feb-2018

To date, examining patient tissue samples has meant cutting them into thin slices for histological analysis. This might now be set to change – thanks to a new staining method devised by an interdisciplinary team from the Technical University of Munich (TUM). This allows specialists to investigate ...

New insights into how your brain keeps its balance

23-Jan-2018

As with all things in life, healthy brain function depends on a balance of forces. We think of our brains as active - moving a leg and saying a word are all "active" events. But it is just as important for our brains to be able to stop these actions -to stop our leg, and to stop our speech. But ...

DNA study casts light on century-old mystery of how cells divide

22-Jan-2018

Scientists have solved a longstanding puzzle of how cells are able to tightly package DNA to enable healthy cell division. Their findings shed light on how single cells can compact DNA 10,000-fold to partition it between two identical cells - a process that is essential for growth, repair and ...

New sensor measures calcium concentrations deep inside tissue

01-Dec-2017

Key processes in the body are controlled by the concentration of calcium in and around cells. A team from the Technical University of Munich (TUM) and the Helmholtz Zentrum München have developed the first sensor molecule that is able to visualize calcium in living animals with the help of a ...

Clever use of mirrors boosts performance of light-sheet microscope

21-Nov-2017

Using a simple "mirror trick" and not-so-simple computational analysis, scientists affiliated with the Marine Biological Laboratory (MBL) have considerably improved the speed, efficiency, and resolution of a light-sheet microscope, with broad applications for enhanced imaging of live cells and ...

Extraordinarily strong nonlinear optical graphene-like material could renovate nonlinear photonics

The discovery could enable high resolution imagining at low-power

26-Oct-2017

Nonlinear optics is a key enabling technology of our modern society, such as in imaging and high-speed data communication. But the traditional devices suffer from relatively small nonlinear optical coefficients of conventional optical materials. An interdisciplinary team of scientists from Aalto ...

Cool microscope technology revolutionises biochemistry

04-Oct-2017

We may soon have detailed images of life’s complex machineries in atomic resolution. The Nobel Prize in Chemistry 2017 is awarded to Jacques Dubochet, Joachim Frank and Richard Henderson for the development of cryo-electron microscopy, which both simplifies and improves the imaging of ...

Quick and reliable 3-D imaging of curvilinear nanostructures

08-Sep-2017

Physical and biological sciences increasingly require the ability to observe nano-sized objects. This can be accomplished with transmission electron microscopy (TEM), which is generally limited to 2D images. Using TEM to reconstruct 3D images instead usually requires tilting the sample through an ...
