LiftPose3D: Turning 2D images into 3D models
LiftPose3D: Turning 2D images into 3D models
Scientists have developed a deep learning-based method called LiftPose3D, which can reconstruct 3D animal poses using only 2D poses from one camera. This method will have impact in neuroscience and bioinspired robotics. "When people perform experiments in neuroscience they have to make precise measurements of behavior," says Professor Pavan Ramdya at EPFL's School of Life Sciences, who led the study.

Do we live in online bubbles?
Do we live in online bubbles?
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.

Running quantum software on a classical computer
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.

From imaging neurons to measuring their true activity
From imaging neurons to measuring their true activity
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.

Early endeavours on the path to reliable quantum machine learning
Early endeavours on the path to reliable quantum machine learning
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.

Mass scale manipulation of Twitter Trends discovered
Mass scale manipulation of Twitter Trends discovered
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.

Quantum computing: cold chips can control qubits
Quantum computing: cold chips can control qubits
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'.

Light meets superconducting circuits
Light meets superconducting circuits
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.

Precise touch screens thanks to AI
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.

Contact-tracing apps prove that they save lives
Contact-tracing apps prove that they save lives
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.

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.

New tech builds ultralow-loss integrated photonic circuits
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.

Uncovering the secrets of some of the world's first color photographs
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.

Designing better antibody drugs with artificial intelligence
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.

Topological data analysis can help predict stock-market crashes
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.
