Taking a novel perspective, researchers have studied political polarization in online news consumption rather than content production, looking at whether the backlink structure of online news networks alone, or users' explicit reading choices contribute to the partisan divide. In the past decade it seems political polarization has been on the rise, as measured by voting behavior and general affect towards opposing partisans and their parties.

Two physicists, from EPFL and Columbia University, have introduced an approach for simulating the quantum approximate optimization algorithm using a traditional computer. Instead of running the algorithm on advanced quantum processors, the new approach uses a classical machine-learning algorithm that closely mimics the behavior of near-term quantum computers.

Neuroscientists often use calcium imaging to analyze neuronal activity in the intact brain. But this method provides only an indirect and slow measure of action potential firing, creating the need to reliably reconstruct action potentials from calcium signals. Peter Rupprecht, a former PhD candidate in the Friedrich group, developed a novel algorithm based on machine learning that is very effective, easy to use, and highly robust.

EPFL and the Paul Scherrer Institute (PSI) join forces to establish a new PSI research division: Scientific Computing, Theory, and Data. In collaboration with EPFL, the Paul Scherrer Institute (PSI) is officially expanding its own focus areas and establishing a new research division: Scientific Computing, Theory, and Data.

The future quantum computers should be capable of super-fast and reliable computation. Today, this is still a major challenge. Now, computer scientists led by ETH Zurich conduct an early exploration for reliable quantum machine learning. Anyone who collects mushrooms knows that it is better to keep the poisonous and the non-poisonous ones apart.

New EPFL research has found that almost half of local Twitter trending topics in Turkey are fake, a scale of manipulation previously unheard of. It also proves for the first time that many trends are created solely by bots due to a vulnerability in Twitter's Trends algorithm. Social media has become ubiquitous in our modern, daily lives.

A cryogenic controller chip opens the door to solving the 'wiring bottleneck' and subsequently to realize a fully integrated, scalable quantum computer. A research from QuTech in the Netherlands, from Intel Corp and from EPFL. A specially designed chip to control qubits can operate at extremely low temperatures, and opens the door to solving the 'wiring bottleneck'.

Researchers have developed a light-based approach to read out superconducting circuits, overcoming the scaling-up limitations of quantum computing systems. In the last few years, several technology companies including Google, Microsoft, and IBM, have massively invested in quantum computing systems based on microwave superconducting circuit platforms in an effort to scale them up from small research-oriented systems to commercialized computing platforms.

Fewer typing errors when touching a smartphone keyboard: ETH Computer scientists have developed a new AI solution that enables touchscreens to sense with eight times higher resolution than current devices. Thanks to AI, their solution can infer much more precisely where fingers touch the screen. We are probably all familiar with this: if you want to quickly type a message on your smartphone, you sometimes hit the wrong letters on the small keyboard - or on other input buttons in an app.

A study published today in Nature shows that the NHS COVID-19 app for digital contact tracing, based on the DP3T protocol, averted between 300,000 and 600,000 COVID-19 cases in England and Wales. The researchers used data from the NHS to show and quantify the epidemiological impact of such privacy-preserving apps, which are now available around the globe to help control the pandemic.

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.

Scientists have developed ultralow-loss silicon nitride integrated circuits that are central for many photonic devices, such as chip-scale frequency combs, narrow-linewidth lasers, coherent LiDAR, and neuromorphic computing. Encoding information into light, and transmitting it through optical fibers lies at the core of optical communications.

Researchers have shed new light on one of the earliest color photography techniques, G. Lippmann's Nobel Prize-winning multispectral imaging method. It is often said that before air travel our skies were bluer yet how, in the 21 st century, could we ever know what light and colors were like one hundred years ago? Recently, a group of researchers from EPFL's Audiovisual Communications Laboratory , in the School of Computer and Communication Sciences (IC), had a unique opportunity to try to find out.

Machine learning methods help to optimise the development of antibody drugs. This leads to active substances with improved properties, also with regard to tolerability in the body. Antibodies are not only produced by our immune cells to fight viruses and other pathogens in the body. For a few decades now, medicine has also been using antibodies produced by biotechnology as drugs.

Scientists, together with local startup L2F, have developed a robust model that can predict when a systemic shift is about to occur, based on methods from a branch of mathematics called topological data analysis. Topological data analysis (TDA) involves extracting information from clouds of data points and using the information to classify data, recognize patterns or predict trends, for example.

Even minor disruptions in infrastructure systems can have fatal consequences. Researchers and practitioners counter that risk by taking action on multiple levels. Four examples. Urban systems: increase resilience By trade, Božidar Stojadinovic is an expert in earthquake-proof construction. Now a Professor of Structural Dynamics and Earthquake Engineering, he specialises in urban systems and how to make them more resilient to earthquakes.

EPFL will soon be home to a European hub for high-performance computing focused on fusion power - a potential source of clean, risk-free energy. As part of this effort, EPFL's Swiss Plasma Center will lead a campus-wide, cross-disciplinary research team. EUROfusion - or the European Consortium for the Development of Fusion Energy, which consists of organizations from 28 European countries - has just selected EPFL as the site for its Advanced Computing Hub.

When a person taps with their fingers, each finger generates a different vibration profile propagating to the wrist through bones. ETH Zurich researchers have now leveraged this discovery in the development of a dual-sensor wristband that brings intuitive free-hand interaction to virtual productivity spaces.

Competence centre for data science Statistical methods, data science and artificial intelligence: the FSO and UniNE intensify their cooperation 25. The University of Neuchâtel (UniNE) and the Federal Statistical Office (FSO) are reinforcing their cooperation in the field of data science and statistical methods.

A digital twin of our planet is to simulate the Earth system in future. It is intended to support policy-makers in taking appropriate measures to better prepare for extreme events. A new strategy paper by European scientists and ETH Zurich computer scientists shows how this can be achieved. To become climate neutral by 2050, the European Union launched two ambitious programmes: " Green Deal " and " DigitalStrategy ".
