New metamaterial offers reprogrammable properties
New metamaterial offers reprogrammable properties
Scientists have developed a metamaterial whose mechanical properties can be reprogrammed on demand and whose internal structure can be modified by applying a magnetic field.  Over the past 20 years, scientists have been developing metamaterials, or materials that don't occur naturally and whose mechanical properties result from their designed structure rather than their chemical composition.

Machine learning helps retrace evolution of classical music
Machine learning helps retrace evolution of classical music
Researchers in EPFL's Digital and Cognitive Musicology Lab in the College of Humanities used an unsupervised machine learning model to 'listen to' and categorize more than 13,000 pieces of Western classical music, revealing how modes - such as major and minor - have changed throughout history. Many people may not be able to define what a minor mode is in music, but most would almost certainly recognize a piece played in a minor key.

On the way to lifelike robots
On the way to lifelike robots
In order for robots to be able to achieve more than simple automated machines in the future, they must not only have their own "brain". Empa researchers postulate that artificial intelligence must be expanded to include the capabilities of a Physical Artificial Intelligence, PAI. This will redefine the field of robotics and the relationship between man and machine.

450 logic errors found in popular databases
Database systems are under pressure to become more and more powerful. But reliability seems to be suffering as a result. Now, ETH computer scientists have developed a tool to automatically detect logic errors in database systems using three different methods. They found and reported over 450 unique, previously unknown bugs.

Soot particles influence global warming more than assumed
A team of researchers from ETH Zurich has used simulations on the CSCS supercomputer "Piz Daint" to investigate how ageing mechanisms of soot particles in the atmosphere affect cloud formation. The results show that the influence of ozone and sulfuric acid on soot ageing alters cloud formation and, ultimately, the climate.

Our actual attention is now measurable
Our actual attention is now measurable
We want to make sure our phones no longer disturb us at the wrong moment. To achieve this, we first have to better understand where our attention lies when using smartphones. Computer scientists at ETH have now developed a system that records eye contact with the display in everyday situations for the first time.

EPFL's Predikon: predicting voting results with machine learning
On September 27 Switzerland votes for the first time since the COVID-19 pandemic began, including on a contentious initiative to end the free movement of workers with the European Union. Predikon will be predicting the final outcome within minutes of the release of the first partial municipal results from the Swiss Federal Statistical Office.

Thousands of seismometers on a single cable
Thousands of seismometers on a single cable
Fibre-optic cables are emerging as a valuable tool for geoscientists and glaciologists. They offer a relatively inexpensive way of measuring even the tiniest glacial earthquakes - plus they can also be used to obtain more accurate images of the geological subsurface in earthquake-prone megacities. Today's fibre-optic cables move data at tremendous speeds, enabling us to stream films and TV shows in HD or even 8K resolution.

Artificial intelligence explains hydrogen's behavior on giant planets
Artificial intelligence explains hydrogen's behavior on giant planets
Using computer simulations powered by machine-learning algorithms EPFL scientists have made an important breakthrough in understanding how hydrogen behaves on Saturn and Jupiter. The giant planets in our solar system are made mainly of hydrogen, mostly in a liquid state. Near the planets- surface, hydrogen exists in an insulating, molecular form - H2 - but closer to the center, it takes on a metallic form where individual atoms can move around freely.
