Artificial intelligence improves biomedical imaging

01-Oct-2019

ETH researchers use artificial intelligence to improve quality of images recorded by a relatively new biomedical imaging method. This paves the way towards more accurate diagnosis and cost-effective devices. Scientists at ETH Zurich and the University of Zurich have used machine learning methods ...

Resistance can spread even without the use of antibiotics

06-Sep-2019

Antibiotic resistance does not spread only where and when antibiotics are used in large quantities, ETH researchers conclude from laboratory experiments. Reducing antibiotic use alone is therefore not sufficient to curtail resistance, and should be done in conjunction with measures to prevent ...

Smart interaction between proteins

21-Aug-2019

Very little was known till now about DNA repair by homologous recombination, which is fundamental for human health. Now an ETH research group has for the first time isolated and studied all the key proteins involved in this process, laying the foundation for investigating many diseases. Within ...

A catalyst for sustainable methanol

01-Aug-2019

Scientists at ETH Zurich and oil and gas company Total have developed a new catalyst that converts CO2 and hydrogen into methanol. Offering realistic market potential, the technology paves the way for the sustainable production of fuels and chemicals. The global economy still relies on the fossil ...

Listening to the whispers of individual cells

30-Jul-2019

For the cells in our bodies to function as a unit, they must communicate with one another constantly. They secrete signalling molecules – ions, proteins and nucleic acids – that are picked up by adjacent cells, which in turn pass on the signal to other cells. Our muscles, digestive system and ...

How multicellular cyanobacteria transport molecules

16-Jul-2019

Researchers from ETH Zurich and the University of Tübingen have taken a high-resolution look at the structure and function of cell-to-cell connections in filamentous, multicellular cyanobacteria. This enables them to explain how these microorganisms regulate the transport of various substances ...

Making systems robust: Artificial genetic regulatory network introduced into living cell for the first time

Improving biotech and therapies

24-Jun-2019

Both nature and technology rely on integral feedback mechanisms to ensure that systems resist external perturbations. ETH researchers have now used synthetic biology to design a new mechanism of this sort from scratch. For the first time, they have introduced it into a living cell as an ...

When sand behaves like oil

08-May-2019

Sand, coffee grounds and rice behave very differently than water or oil, but under certain conditions they will suddenly exhibit astonishing similarities. Scientists have found a way to better understand the behaviour of granular materials. Sand, rice and coffee are all examples of granular ...

Fleming’s method in miniature

02-May-2019

Scientists in the Department of Biosystems Science and Engineering at ETH Zurich in Basel have developed a method with which they can quickly test a very large number of molecules for antibiotic effect. With it, they have already successfully discovered new antibiotic candidates produced by ...

Bacteria reveal strong individuality when navigating a maze

26-Apr-2019

Researchers from ETH Zurich demonstrate that genetically identical cells exhibit differing responses in their motility towards chemical attractants. Average values hide the full picture when it comes to describing the behaviour of bacteria. Although they are considered the simplest of all life ...
