Bigger synapse, stronger signals
Bigger synapse, stronger signals
Nerve cells communicate with one another via synapses. Neuroscientists at the University of Zurich and ETH Zurich have now found that these connections seem to be much more powerful than previously thought. The neocortex is the part of the brain that humans use to process sensory impressions, store memories, give instructions to the muscles, and plan for the future.

How our planets were formed
How our planets were formed
Terrestrial planets versus gas and ice giants: A new theory explaining why the inner solar system is so different to the outer regions runs counter to the prevailing wisdom. The theory was proposed by an international research group with ETH Zurich's participation. Mercury, Venus, Earth and Mars in the inner solar system are relatively small, dry planets, unlike Jupiter, Saturn, Uranus and Neptune in the outer regions, planets that contain much greater quantities of volatile elements.

How recruiters discriminate on employment websites
How recruiters discriminate on employment websites
Researcher on conducted a large-scale study of discrimination on an online recruitment platform. The findings showed that, depending on the occupation, both men and women suffer from discrimination, and that discrimination against foreigners depends, among other things, on the time of day. Discrimination in hiring is a major societal problem.

How clicks on a job platform can reveal bias
How clicks on a job platform can reveal bias
Scientists at ETH Zurich have leveraged big data from recruitment platforms and machine learning to study hiring discrimination. They show that discrimination against immigrants depends, among other things, on the time of day; and that both men and women face discrimination. Education, professional skills and experience are the essential criteria for filling a position - or at least that is the expectation.

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.

Snap-freezing reveals a truer structure of brain connections
Snap-freezing reveals a truer structure of brain connections
Scientists at EPFL have used a snap-freezing method to reveal the true structure of the connections that join neurons together in the adult brain. Most synaptic connections in the adult brain are situated on dendritic spines; small, micrometer-long, protrusions extending from the neurons' surface. The spines' exact size and shape determine how well signals are passed from one neuron to another.

Changing resilience of oceans to climate change
Changing resilience of oceans to climate change
Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. An international team of scientists led by ETH Zurich used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago - and found limited expansion of seafloor anoxia (absence of oxygen).

Protecting the genome from transposon activation
Protecting the genome from transposon activation
Transposons are foreign DNA elements capable of random insertion into the genome, an event that can be very dangerous for a cell. Their activity must be silenced to maintain genomic integrity, which is primarily achieved by H3K9me3-mediated repression. Researchers from the Gasser group identified two parallel pathways that are essential for H3K9me3- mediated transcriptional repression and thus for protecting the genome from toxic transposon activation.

How aerosols are formed
How aerosols are formed
ETH Zurich researchers conducted an experiment to investigate the initial steps in the formation of aerosols. Their findings are now aiding efforts to better understand and model that process - for example, the formation of clouds in the atmosphere. Aerosols are suspensions of fine solid particles or liquid droplets in a gas.

How the circadian clock regulates liver genes in time and space
How the circadian clock regulates liver genes in time and space
Scientists have carried out the first comprehensive study of how genes in the liver perform their metabolic functions in both space and time of day. Monitoring almost 5000 genes at the level of the individual cell across a 24-hour period, the researchers have modelled how the circadian clock and liver functions crosstalk throughout the day in sync with the feeding-fasting cycle.

How to Keep Drones Flying When a Motor Fails
How to Keep Drones Flying When a Motor Fails
Robotics researchers at the University of Zurich show how onboard cameras can be used to keep damaged quadcopters in the air and flying stably - even without GPS. As anxious passengers are often reassured, commercial aircrafts can easily continue to fly even if one of the engines stops working. But for drones with four propellers - also known as quadcopters - the failure of one motor is a bigger problem.

Electrically switchable qubit can tune between storage and fast calculation modes
To perform calculations, quantum computers need qubits to act as elementary building blocks that process and store information. Now, physicists have produced a new type of qubit that can be switched from a stable idle mode to a fast calculation mode. The concept would also allow a large number of qubits to be combined into a powerful quantum computer, as researchers from the University of Basel and TU Eindhoven have reported in the journal -Nature Nanotechnology-.
