AI helps detecting plastic in oceans
A research team from EPFL and Wageningen University has developed a new artificial intelligence model that recognises floating plastics much more accurately in satellite images than before. This could help to systematically remove plastic litter from the oceans with ships. Our society relies heavily on plastic products and the amount of plastic waste is expected to increase in the future.

Better energy efficiency in data processing
Developed by researchers, the first large-scale in-memory processor using 2D semiconductor materials could substantially cut the ICT sector's energy footprint. As information and communication technologies (ICT) process data, they convert electricity into heat. Already today, the global ICT ecosystem's CO2 footprint rivals that of aviation.

A game changer for building robust distributed systems
Researchers have developed a new distributed algorithm that, for the first time, solves one of the key performance and reliability problems affecting most of the currently-deployed consensus protocols. Consensus is one of the fundamental problems in distributed systems. It allows a group of machines to maintain multiple copies of data and update them consistently, even when a fraction of the machines might fail.

A new EPFL tool shows the decline of political tone in the US
A new EPFL developed tool, Quotebank , has helped researchers provide the first large-scale data-driven evidence of a drastic shift towards a more negative political tone beginning at the start of Donald Trump's primary campaign in June 2015. A vast majority of Americans believe that the tone and nature of political debate in the United States has become more negative in recent years and more than half have the impression that Donald Trump is responsible.

How AI can help uncover the way memory works
A symphony of electrical signals and a dynamic tangle of connections between brain cells help us to make new memories. Using AI-powered models of groups of neurons, FMI researchers are working towards unlocking how the brain orchestrate this dance. Their latest study has achieved a major advance in accurately simulating the changes in the connections between neurons that sense the external environment, opening the door to a greater understanding of how countless brain cells transform sensations into perceptions and thoughts.

Virtual rail noise - close to reality
At Empa, acoustics experts have been investigating for years how noise is generated by passenger and cargo trains - and which technical and structural measures are particularly effective to prevent or at least reduce it. Their findings have now been incorporated into the SILVARSTAR project resulting in a simulation tool for rail noise that can help in practice.

Planting ideas in a computer’s head
Researchers at ETH Zurich have found a new attack on AMD computer chips in which the attacker plants an "idea" in the computer without it noticing. Using that attack, it was possible to leak data from anywhere in the computer's memory. Everyone has, at one time or another, experienced how dreams can influence our moods and actions.

Unveiling the origins of merging black holes in galaxies like our own
Harnessing advanced simulation tools, a team of scientists from UNIGE, Northwestern University and University of Florida shed light on the enigmatic nature of these celestial "beasts". Black holes, some of the most captivating entities in the cosmos, possess an immense gravitational pull so strong that not even light can escape.

Schrödinger's cat makes better qubits
Drawing from Schrödinger's cat thought experiment, scientists at EPFL have built a "critical cat code" qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs. Quantum computing uses the principles of quantum mechanics to encode and elaborate data, meaning that it could one day solve computational problems that are intractable with current computers.

DeepBreath: Using deep learning to identify respiratory disease
A new AI algorithm developed at EPFL and University Hospital Geneva (HUG) will power an intelligent stethoscope - Pneumoscope - with the potential to improve the management of respiratory disease in low-resource and remote settings. As air passes through the labyrinth of small passageways in our lungs, it makes a distinctive whooshing sound.

Safe Aid: Protecting privacy in humanitarian operations
Researchers have worked with the International Committee of the Red Cross (ICRC) to develop a first of its kind, digital system to support humanitarian aid distribution. The design uses tokens to decentralize the storage and processing of recipients information, reducing the risk of harm, and uses advanced cryptography to enable accountability.

’For very small problem sizes a classical computer is faster’
In theory, quantum computers vastly outperform classical computers in terms of computing speed. For them to do so in practice, it is necessary to design more and novel high-speed algorithms, says ETH supercomputing specialist Torsten Hoefler. Quantum computers promise to be capable of solving some computational problems much faster than classical computers.

Researchers successfully apply quantum computing in practice
Compared to classical computers, quantum computers can solve complex problems in parallel and thus faster, but they are also more prone to errors. ZHAW researchers show how a hybrid approach can be used to exploit the strengths of quantum computers in a targeted manner. Quantum computers not only know the state 0 and 1, but can also represent several states between 0 and 1 by means of so-called qubits - analogous to bits of classical computers - and thus calculate many possible results simultaneously.
