Mechanism discovered how the coronavirus hijacks the cell

A starting point for vaccine and drug development

15-Sep-2020

Researchers at ETH Zurich and the University of Bern have discovered a mechanism by which the corona virus manipulates human cells to ensure its own replication. This knowledge will help to develop drugs and vaccines against the corona virus. Like a pirate hijacking a ship, a virus takes control ...

Electron movements in liquid measured in super-slow motion

“Electron movements are the key events in chemical reactions”

24-Aug-2020

Electrons are able to move within molecules, for example when they are excited from outside or in the course of a chemical reaction. For the first time, scientists have now succeeded in studying the first few dozen attoseconds of this electron movement in a liquid. To understand how chemical ...

A new biosensor for the COVID-19 virus

Detection in the environment

23-Apr-2020

A team of researchers from Empa, ETH Zurich and Zurich University Hospital has succeeded in developing a novel sensor for detecting the new coronavirus. In future it could be used to measure the concentration of the virus in the environment - for example in places where there are many people or ...

New COVID-19 test quickly and accurately detects viral RNA

17-Apr-2020

Millions of people have been tested for the novel coronavirus, most using a kit that relies on the polymerase chain reaction (PCR). This sensitive method amplifies SARS-CoV-2 RNA from patient swabs so that tiny amounts of the virus can be detected. However, as the pandemic surges, this laboratory ...

X-ray vision through the water window

14-Apr-2020

ETH physicists have developed the first high-​repetition-rate laser source that produces coherent soft x-​rays spanning the entire ‘water window’. That technological breakthrough should enable a broad range of studies in the biological, chemical and material sciences as well as in physics. The ...

Fast, sensitive blood tests for use at home

03-Mar-2020

They should be fast, portable and easy to use: blood tests that can be done at home. Having already come up with a prototype, ETH Pioneer Fellow Alexander Tanno is working with doctoral student Yves Blickenstorfer to bring the idea to market. The prototype that Alexander Tanno is holding between ...

Observing changes in the chirality of molecules in real time

19-Nov-2019

Chiral molecules - compounds that are mirror images of each other - play an important role in biological processes and in chemical synthesis. Chemists at ETH Zurich have now succeeded for the first time in using ultrafast laser pulses to observe changes in chirality during a chemical reaction in ...

Monitoring the corrosion of bioresorbable magnesium

Better prediction of degradation rate of magnesium implants

28-Oct-2019

ETH researchers have recently been able to monitor the corrosion of bioresorbable magnesium alloys at the nanoscale over a time scale of a few seconds to many hours. This is an important step towards accurately predicting how fast implants are resorbed by the body to enable the development of ...

Mini-spectrometer: Smaller than a coin

09-Oct-2019

ETH researchers have developed a compact infrared spectrometer. It’s small enough to fit on a computer chip but can still open up interesting possibilities – in space and in everyday life. Nowadays, a mobile phone can do almost anything: take photos or video, send messages, determine its present ...

Healthy organelles, healthy cells

02-Oct-2019

It has recently become clear just how important membraneless organelles are for cells. Now biochemists at ETH Zurich have discovered a novel mechanism that regulates the formation of these organelles. This has laid the foundation for more targeted research into diseases such as Alzheimer’s or ...
