Fingerprint spectroscopy within a millisecond

Quality control in real time for the use in the pharmaceutical, chemical and food industry

25-Jun-2019

To guarantee high quality pharmaceuticals, manufacturers need not only to control the purity and concentration of their own products, but also those of their suppliers. Researchers at the Fraunhofer Institute for Applied Solid State Physics IAF have developed a measuring system capable of ...

Real-time analysis of MOF adsorption behavior

24-Jun-2019

Researchers have developed a technology to analyze the adsorption behavior of molecules in each individual pore of a metal organic framework (MOF). This system has large specific surface areas, allowing for the real-time observation of the adsorption process of an MOF, a new material effective ...

Cancer control: Structure of important transport protein solved

Discovery of promising binding site

21-Jun-2019

For the first time, Bernese researchers have been able to solve the structure of a transport protein and thus to describe the functional mechanism that plays a significant role in the survival of cancer cells. This is an important step towards developing effective inhibitors and fight tumor ...

New Quantum Dot Microscope Shows Electric Potentials of Individual Atoms

17-Jun-2019

A team of researchers from Jülich in cooperation with the University of Magdeburg has developed a new method to measure the electric potentials of a sample at atomic accuracy. Using conventional methods, it was virtually impossible until now to quantitatively record the electric potentials that ...

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 ...

How to separate nanoparticles by “shape”

New strategy to separate molecules

13-Jun-2019

In our daily lives, the purpose and function of an item is defined by either its material, e.g. a rain jacket is fabricated of water-proof material, or its shape, e.g. a wheel is round to enable a rolling motion. What is the impact of the two factors on the nanoscale? The impact of material, ...

Learning from Nature’s Bounty: New Libraries for Drug discovery

12-Jun-2019

Natural products, or their close derivatives, make some of our most potent medicines, among which macrocycles with their large carbon-rich ring systems are one class. The size and complexity of macrocycles has made it difficult to emulate and build on Nature’s success in the laboratory. By ...

Fiber-optic probe can see molecular bonds

Pointing the new nanoscopy tool like a Harry Potter wand reveals a high-resolution image of molecules

12-Jun-2019

In "Avengers: Endgame," Tony Stark warned Scott Lang that sending him into the quantum realm and bringing him back would be a "billion-to-one cosmic fluke." In reality, shrinking a light beam to a nanometer-sized point to spy on quantum-scale light-matter interactions and retrieving 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 - ...

Dynamics of key viral attack strategy visible for first time

Visualizing and quantifying frameshifting mechanisms in living cells

11-Jun-2019

Many infectious viruses, from HIV to West Nile, rely on a fundamental biological process called frameshifting to maximize their attack. Long identified as a key mechanism that viruses use to proliferate inside their hosts, the real-time dynamics of frameshifting had never been directly observed, ...
