New primary method for the measurement of pressure based on electrical measurements carried out on helium gas

04-Dec-2019

Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have implemented a novel pressure measurement method, quasi as a byproduct of the work on the "new" kelvin. In addition to being new, this procedure is a primary method, i.e. it only depends on natural constants. As an independent ...

Magnetic nanoparticles with ionic liquids for water purification

Providing Safe, Clean Water

03-Dec-2019

In many parts of the world, access to clean drinking water is far from certain. Filtration of large volumes of water, however, is slow and impractical. In the journal Angewandte Chemie, scientists have introduced a new water purification method based on magnetic nanoparticles coated with a ...

New catalyst: easy on resources, less expensive, and highly selective

02-Dec-2019

Chemists at the University of Bayreuth have developed a sustainable, inexpensive, and at the same time potent catalytic process: it requires no rare precious metals and enables the targeted production of many fine chemicals, natural products, and medical agents. This opens up a broad spectrum of ...

Key to rubustness of plants discovered

Mechanism of Adipose-Biosynthesis decoded – the basis for the production of sugar molecules for neu fine chemicals or biopharmaceuticals

27-Nov-2019

In every weather situation, plants need to be robust and flexible at the same time. These structural properties come from its cell wall: It’s responsible to keep the plant in shape, to compensate its osmotic pressure and to protect it against pathogens e.g. bacteria, viruses or fungal attacks. ...

Rapid emergence of antibiotic resistance during standard therapy

How the pathogen Pseudomonas aeruginosa becomes resistant to antibiotics

25-Nov-2019

Antibiotic-resistant pathogens pose one of the greatest threats to public health worldwide. In the near future, harmless bacterial infections may no longer be treatable and may again become the most common non-natural cause of death. At the same time, the available repertoire of antibacterial ...

Self-restrained genes enable evolutionary novelty

22-Nov-2019

Changes in the genes that control development can potentially make large contributions to evolution by generating new morphologies in plants and animals. However, because developmental genes frequently influence many different processes, changes to their expression carry a risk of “collateral ...

Cell death or cancer growth: a question of cohesion

21-Nov-2019

Activation of CD95, a receptor found on all cancer cells, triggers programmed cell death – or does the opposite, namely stimulates cancer cell growth. Scientists from the German Cancer Research Center (DKFZ) have now shown that the impact of CD95 activation depends on whether there are isolated ...

High-fat maternal diet can cause brain damage in the unborn child

20-Nov-2019

A study team at MedUni Vienna’s Center for Brain Research has found that high-fat maternal diets can cause life-long changes in the brain of the unborn offspring. When a pregnant woman consumes a diet high in polyunsaturated omega-6 fatty acids, her body produces an excess of endogenous ...
