How cells correct errors under time pressure
How cells correct errors under time pressure
How does a cell balance risk and speed when dividing? scientists have developed and experimentally tested the first mathematical theory that describes the cell's best strategy for dividing safely and efficiently. Cells go through a life cycle that includes growing to the right size, being equipped to perform its functions, and finally dividing into two new cells.

Enhancer-promoter interactions - distance matters
Enhancer-promoter interactions - distance matters
When and where a gene is transcribed in a living organism often depends on its physical interactions with distal genomic regulatory regions called enhancers. Researchers in the group of Luca Giorgetti have thrown light on how such interactions control transcription thanks to a novel ingenious experimental approach combined with mathematical modelling.

Build neurons with mathematics
Build neurons with mathematics
Researchers from EPFL have found a way to use only mathematics to automatically draw neurons in 3D, meaning we are getting closer to being able to build digital twins of brains. Santiago Ramón y Cajal, a Spanish physician from the turn of the 19 th century, is considered by most to be the father of modern neuroscience.

Mathematics helps AI in biomedicine
Mathematics helps AI in biomedicine
"Data is the new oil", it has often been said. Indeed, in the digital age data is the fuel that runs the engines of digital media, advanced informatics (AI, machine learning etc.) and, not least, scientific research. Nevertheless, when facing certain highly complex issues, data-driven approaches may not always be the most effective solutions.

A mathematical secret of lizard camouflage
A mathematical secret of lizard camouflage
A multidisciplinary team at the University of Geneva has succeeded in explaining the complex distribution of scales in the ocellated lizard by meansáof a simple equation. The shape-shifting clouds of starling birds, the organization of neural networks or the structure of an anthill: nature is full of complex systems whose behaviors can be modeled using mathematical tools.

Securing data transfers with relativity
Securing data transfers with relativity
A team from the University of Geneva has implemented a new way to secure data transfers based on the physical principle of relativity. The volume of data transferred is constantly increasing, but the absolute security of these exchanges cannot be guaranteed, as shown by cases of hacking frequently reported in the news.

Improving contact-tracing apps in the COVID-19 era
Improving contact-tracing apps in the COVID-19 era
An international collaboration with EPFL has developed a method to improve the performance of COVID-19 contact-tracing apps by taking into account a user's recent contacts, risk levels and shared information about tests and symptoms. Contact-tracing apps like SwissCovid have enormous potential to mitigateáthe spread of the COVID-19 pandemic.

Four cryptographic vulnerabilities in Telegram
Four cryptographic vulnerabilities in Telegram
An international research team of cryptographers completed a detailed security analysis of the popular Telegram messaging platform identifying several weaknesses in its protocol that demonstrate the product falls short of some essential data security guarantees. Working with only open-source code and without "attacking" any of Telegram's running systems, a small team of international researchers completed a detailed analysis of the company's encryption services.

Modeling the friction between pages in a book
Modeling the friction between pages in a book
Engineers at EPFL and ╔cole Polytechnique in France analyzed the friction between pages in a book and the mechanical force needed to bend them. Drawing on their experiments, they developed a new theoretical model for predicting the elasto-frictional behavior of stacked layers. It all started with a shaky washing machine.

USI develops innovative system for better credit card fraud detection
USI develops innovative system for better credit card fraud detection
The use of credit cards and other cashless or digital payment methods has become the norm for consumers all over the globe, and the strong surge of online buying during the pandemic has further boosted this decade-long trend. However, behind the convenience of 'click and pay' there are also risks, such as fraud and related losses, which are mostly borne by the card companies.

Theory and experiments to understand a contact between two filaments
Theory and experiments to understand a contact between two filaments
Mechanical engineers and mathematicians at EPFL have joined forces to gain a better understanding of the geometry and mechanics of two filaments in contact - as in the cases of knots and woven fabrics. Pedro Reis, head of EPFL's Flexible Structures Laboratory, and John Maddocks, head of EPFL's Laboratory for Computation and Visualization in Mathematics and Mechanics, have something in common: a fascination with ropes and knots.

On the trail of Sars-CoV-2 in cable cars
Where do the greatest risks of infection lurk? How can you protect yourself and others even better? Scientists all over the world are working to expand knowledge about Covid-19 - including at Empa. Researchers are now using measurements and simulations to take a close look at cable cars and cabins in ski resorts.

A NEAT reduction of complex neuronal models accelerates brain research
A NEAT reduction of complex neuronal models accelerates brain research
Unlike their simple counterparts in artificial intelligence (AI) applications, neurons in the brain use dendrites - their intricate tree-like branches - to find relevant chunks of information. Now, neuroscientists from the University of Bern have discovered a new computational method to make complex dendrite models much simpler.

Researchers compute turbulence with artificial intelligence
Researchers compute turbulence with artificial intelligence
For the first time, researchers at ETH Zurich have successfully automated the modelling of turbulence. Their project relies on fusing reinforcement learning algorithms with turbulent flow simulations on the CSCS supercomputer "Piz Daint". The modelling and simulation of turbulent flows is crucial for designing cars and heart valves, predicting the weather, and even retracing the birth of a galaxy.

The same visual system for all primates
The world's smallest primate reveals the incredible preservation of our visual system through millions of years of evolution. Primates process visual information in front of their eyes, similar to pixels in a digital camera, using small computing units located in the visual cortex of their brains.

Mathematical program helps perform more efficient radiosurgery
Mathematical program helps perform more efficient radiosurgery
Engineers at EPFL and local startup Intuitive Therapeutics have developed software that can produce optimized surgical plans for Gamma Knife radiosurgery. Doctors at the Lausanne University Hospital (CHUV) began using the software in July. Radiosurgery is a kind of radiotherapy where doctors administer a high dose of radiation to diseased tissue with extreme precision, and in one go rather than over several sessions.

Estimating the second wave
Estimating the second wave
ETH researchers are using a new mathematical model to calculate a possible second wave of the pandemic in Switzerland. Even though such a wave would probably grow more slowly than the first without overloading hospitals, its death toll may turn out to be significantly higher. Should Switzerland see a second wave of the coro rus pandemic, it would proceed more slowly than the first.

Mathematics can save lives at sea
An international research collaboration led by ETH Zurich and MIT has developed a mathematical method that can speed up search and rescue operations at sea. The new algorithm accurately predicts locations to which objects and people floating in water will drift. Hundreds of people die at sea every year due to vessel and airplane accidents.

Reconstructing structure and function of a neuronal circuit
Reconstructing structure and function of a neuronal circuit
Reconstructing structure and function of a neuronal circuit The function of neuronal circuits is thought to be determined largely by specific connections between neurons. But this assumption has been difficult to test because the reconstruction of the synaptic connectivity of a neuronal circuit - its "wiring diagram" - is a major challenge.
