A biochemical random number

Scientists have generated a huge true random number using DNA synthesis: It is the first time that a number of this magnitude has been created by biochemical means.

23-Nov-2020

True random numbers are required in fields as diverse as slot machines and data encryption. These numbers need to be truly random, such that they cannot even be predicted by people with detailed knowledge of the method used to generate them. As a rule, they are generated using physical methods. ...

Anti-ageing therapy against metastases

Genetic factor determines whether ageing prostate cancer cells either die or become more aggressive

20-Nov-2020

Scientists discovered a genetic factor that determines whether ageing prostate cancer cells either die or become more aggressive. This finding provides important information for personalised therapy of patients. Aging tumour cells stop proliferating. This cell ageing process is called senescence. ...

Spread of a novel SARS-CoV-2 variant across Europe in summer 2020

There is currently no evidence of this variant being more dangerous

30-Oct-2020

Researchers from Basel and Spain have identified a novel SARS-CoV-2 variant that has spread widely across Europe in recent months, according to an un-peer-reviewed preprint released this week. While there is no evidence of this variant being more dangerous, its spread may give insights into the ...

Millimetre-precision drug delivery to the brain

Method is set to enable treatment of psychiatric and neurological disorders and tumours with fewer side effects in the future.

08-Oct-2020

Researchers at ETH Zurich have developed a method for concentrating and releasing drugs in the brain with pinpoint accuracy. This could make it possible in the future to deliver psychiatric and cancer drugs and other medications only to those regions of the brain where this is medically ...

How ETH Zurich spin-offs strengthen the Swiss economy

ETH spin-​offs are much more likely to make an exit than other Swiss start-​ups

08-Oct-2020

As well as generating more jobs on average than other Swiss start-​ups, ETH spin-​offsare also acquired more frequently. A decisive factor, according to University of St.Gallen’s comprehensive analysis, comes from the institutional support for entrepreneurship. With around 500 ETH spin-​offs now ...

How local forces deform the lipid membranes

Knowledge feeds into the development of better minimal model systems and artificial cells

05-Oct-2020

ETH Zurich researchers have been able to show why biological cells can take on such an astonishing variety of shapes: it has to do with how the number and strength of local forces acting on the cell membrane from within. This knowledge feeds into the development of better minimal model systems ...

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 ...

Let there be light and the process stops

Easy method for dynamically controlling biotechnological substance production

15-Sep-2020

ETH researchers have discovered that they can use light-​sensitive molecules to switch genetic networks on and off as required. Their finding gives rise to an easy method for dynamically controlling biotechnological substance production. Tetracycline (Tc), an antibiotic, and its derivative ...

"Biohackers" TV series stored on DNA

Synthetic genetic material as a stable storage medium - for over 1000 years

03-Sep-2020

The first episode of the newly released series "Biohackers" was stored in the form of synthetic DNA. This was made possible by the research of Prof. Reinhard Heckel of the Technical University of Munich (TUM) and his colleague Prof. Robert Grass of ETH Zürich. They have developed a method that ...

How bacteria adhere to fiber in the gut

Two binding modes allow bacteria to stick to surfaces under flow

01-Sep-2020

Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. Scientists of the University of Basel and ETH Zurich published their results in the journal ...
