New imaging method makes tiny robots visible in the body

Important breakthrough in efficiently merging microrobotics and imaging

16-May-2022

Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-​sized microrobots individually and at high resolution in a living organism. How can a blood clot ...

Bacteria with recording function capture gut health status

“This new method lets us obtain information directly from the gut, without having to disturb intestinal functions”

16-May-2022

Researchers from ETH Zurich, University Hospital of Bern and the University of Bern have equipped gut bacteria with data logger functionality as a way of monitoring which genes are active in the bacteria. These microorganisms could one day offer a noninvasive means of diagnosing disease or ...

A new dimension in transplantation

Technique to transplant mitochondria from one living cell to another

29-Mar-2022

In a technological breakthrough, researchers at ETH Zurich have announced the development of a new technique that can transplant mitochondria – the tiny powerhouses of the cell – from one living cell to another with unparalleled efficiency. Just as the human body can be divided into different ...

Like bacteria firing spearguns

A surprising anchoring in the cell

08-Mar-2022

Biologists from ETH Zurich have discovered speargun-​like molecular injection systems in two types of bacteria and have described their structure for the first time. The special nanomachines are used by the microbes for the interaction between cells and could one day be useful as tools in ...

New drug candidates identified in bacteria

Bacteria show great promise as a source of active ingredients

17-Feb-2022

Using computer-​based genome analysis, researchers at ETH Zurich have now discovered a new class of natural products that might one day serve as antibiotics. Animals, plants, fungi and bacteria – each and every organism carries a whole armoury of chemical compounds that enable it to interact with ...

Agents between good and evil

Theory of narrow host range of phages challenged: consequences for phage therapy?

21-Jan-2022

Viruses that infect bacteria could one day replace antibiotics because they precisely attack only specific pathogens. Researchers at ETH Zurich are now showing that this is not always the case. This new finding is important because bacterial viruses can transfer antibiotic resistance ...

AI offers a faster way to predict antibiotic resistance

Huge new data set combines mass spectrometry data with information on antibiotic resistance

14-Jan-2022

A study under co-leadership of the ETH Zurich has shown that computer algorithms can determine antimicrobial resistance of bacteria faster than previous methods. This could help treat serious infections more efficiently in the future. Antibiotic-resistant bacteria are on the rise all over the ...

Wastewater provides new insight into Covid-19 dynamics

An interdisciplinary team shows that the R number of coronavirus can be estimated quickly and cost-effectively from wastewater

17-Dec-2021

Since the start of the coronavirus (Sars-Cov-2) pandemic, many public health measures have been decided based on its dynamic of spread, more precisely, on the reproductive number of the virus, known as the R number. This value indicates how many people on average are infected by a person carrying ...

Rapid PCR tests at the touch of a button

ETH start-​up diaxxo hope to fundamentally change the way in which PCR testing is deployed in medicine

14-Dec-2021

ETH researchers Michele Gregorini and Philippe Bechtold have developed a PCR testing device that can easily be used outside the lab – and that takes less than 30 minutes to deliver results. Now the two young entrepreneurs are focusing their efforts on getting the device approved for medical ...

Harnessing the organisation of the cell surface

07-Dec-2021

Scientists at ETH Zurich have developed a new method to determine how proteins are organised on the surface of cells. Insights gained with the technology could lead to the development of novel drugs to fight cancer. Biological cells have multiple functions, and they need to communicate with each ...
