Genotoxins discovered for the first time using a novel method

06-Mar-2023

Vegetable oils rich in unsaturated fatty acids are highly recommended for a healthy diet. But these oils are not as healthy as thought: Prof. Dr. Gertrud Morlock, holder of the Chair of Life Sciences at Justus Liebig University Giessen (JLU), together with PhD student Daniel Meyer, has for the ...

Sensor can identify the global content and form of arsenic-containing molecules at very low concentrations

02-Mar-2023

It is a cruel paradox that on a planet with a surface mostly covered by water, hundreds of millions of people don’t have access to clean drinking water. As for the pollution of potable and natural water sources, one of the main culprits is arsenic, an abundant and toxic element in the earth’s ...

Using electron microscopy to create ultrafast movies of nano-processes

27-Feb-2023

A slow-motion movie on sports television channels shows processes in hundredths of a second. By contrast, processes on the nanoscale take place in the so-called femtosecond range: For example, an electron needs only billionths of a second to orbit a hydrogen atom. Physicists around the world are ...

In the future, this could make it easier than ever to determine the safety of many chemical substances

24-Feb-2023

It is known that toxins in tobacco smoke can change our DNA – but where exactly in the genome they do this has been a mystery. A new approach developed by researchers at ETH Zurich now brings light into the darkness. In the future, this could make it easier than ever to determine the safety of ...

"Nanofluidic devices have the potential to become a fantastic experimental tool to elucidate the dynamics of solution reactions"

23-Feb-2023

In a chemical reaction, molecules in different substances meet one another to form new molecules causing changes in the bonds of their atoms. The molecules collide at an extremely close distance—a nanometer or less—in an extremely short amount of time. This makes investigating the details of ...

Researchers have made real-time movies of copper nanoparticles as they evolve to convert carbon dioxide and water into renewable fuels and chemicals

21-Feb-2023

Since the 1970s, scientists have known that copper has a special ability to transform carbon dioxide into valuable chemicals and fuels. But for many years, scientists have struggled to understand how this common metal works as an electrocatalyst, a mechanism that uses energy from electrons to ...

Reaction of high interest to clean-energy innovations is closely analysed in X-ray study

17-Feb-2023

Experiments at DESY’s light sources PETRA III and FLASH have revealed the complex mode of action behind the artificial splitting of water at its most efficient level. Using X-rays, a team led by DESY leading scientist Simone Techert managed to observe the interaction of water with a perovskite, a ...

Live observation of the birth of an electron dissolved in water

17-Feb-2023

A new experiment has made it possible to observe the effects of an electron in solution on the surrounding liquid. So-called hydrated electrons play a major role in many physical, chemical and biological processes. They are not bound to an atom or molecule and are free in the solution. Since they ...
