Repairing synapses to combat multiple sclerosis
Repairing synapses to combat multiple sclerosis
A team from UNIGE, the University of Munich and the Technical Institute of Munich has discovered that the destruction of synapses in the brain's grey matter reduces the activity of neurons in the cerebral cortex and is a major factor in the progression of multiple sclerosis. Multiple sclerosis (MS) is a chronic inflammatory disease that affects the central nervous system, in which nerve cells are attacked by the patient's own immune system.

CHEOPS finds unique planetary system
CHEOPS finds unique planetary system
The CHEOPS space telescope detects six planets orbiting the star TOI-178. Five of the planets are in a harmonic rhythm despite very different compositions. This result challenges our understanding of the formation and evolution of planetary systems. Musical notes that sound pleasant together can form a harmony.

Climate change in antiquity: mass emigration due to water scarcity
Climate change in antiquity: mass emigration due to water scarcity
The absence of monsoon rains at the source of the Nile was the cause of migrations and the demise of entire settlements in the late Roman province of Egypt. This demographic development has been compared with environmental data for the first time by professor of ancient history, Sabine Huebner of the University of Basel - leading to a discovery of climate change and its consequences.

Solar System formation in two steps
Solar System formation in two steps
Why are the planets of the inner Solar System dry and rocky, but the outer ones are not? An international team of researchers with participation of the University of Zurich discovered that a two-step formation process of the planets can explain the chronology and split in volatiles like water and isotope content of the inner and outer Solar System.

MRI helps unravel the mysteries of sleep
MRI helps unravel the mysteries of sleep
Scientists at EPFL and the Universities of Geneva, Cape Town and Bochum have joined forces to investigate brain activity during sleep with the help of MRI scans. It turns out our brains are much more active than we thought. Our state of consciousness changes significantly during stages of deep sleep, just as it does in a coma or under general anesthesia.

TRAPPIST-1's 7 Rocky Planets May Be Made of Similar Stuff
TRAPPIST-1’s 7 Rocky Planets May Be Made of Similar Stuff
The TRAPPIST-1 star is home to the largest batch of roughly Earth-size planets ever found outside our solar system. An international study involving researchers from the Universities of Bern, Geneva and Zurich now shows that the exoplanets have remarkably similar densities, which provides clues about their composition.

Size of Connections between Nerve Cells Determines Signaling Strength
Size of Connections between Nerve Cells Determines Signaling Strength
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 larger the synapse, the stronger the signal it transmits. These findings will enable a better understanding of how the brain functions and how neurological disorders arise.

Study Identifies European Cities with Highest Mortality Due to Air Pollution
Study Identifies European Cities with Highest Mortality Due to Air Pollution
A health impact study has for the first time estimated the mortality burden attributable to air pollution in more than 1,000 European cities. The study, published in The Lancet Planetary Health, includes a ranking of the European cities with the highest rates of mortality attributable to each of the two air pollutants studied: fine particulate matter (PM2.5) and nitrogen dioxide (NO2).

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.

The stores of the future
The stores of the future
Lidl Switzerland aims to operate its stores even more sustainably and efficiently in the future. Together with Empa, the company now puts this plan into practice. First, the energy consumption and the interaction of various operational systems in existing stores will be analyzed. Then, the Empa researchers will develop an optimized concept for the stores of the future based on the findings of their analysis.

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.

Detailed tumour profiling
As part of a clinical study involving patients from the University Hospitals in Zurich and Basel, researchers are conducting a thorough and highly precise investigation into the molecular and functional properties of tumours. Their goal is to help physicians to better determine which treatment will best match every patient's cancer and thus be most effective.

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.

Modelling the energy transition
Modelling the energy transition
An interdisciplinary research team from ETH Zurich is developing the Nexus-e modelling platform in a project supported by the Swiss Federal Office of Energy. The platform facilitates the analysis of how technological, economic and regulatory developments affect the energy system of the future. Switzerland's energy system will undergo a fundamental transformation in the coming years.

NAD+ can restore age-related muscle deterioration
Scientists at EPFL have discovered that Alzheimer's-like protein aggregates underly the muscle deterioration seen in aging. But the aggregates can be reversed by boosting the levels of nicotinamide adenine dinucleotide (NAD + ), which turns on the defense systems of mitochondria in cells and restores muscle function.

How Fellow Students Improve Your Own Grades
Better grades thanks to your fellow students? A study conducted by the University of Zurich's Faculty of Business, Economics and Informatics has revealed that not only the grade point average, gender and nationality peers can influence your own academic achievement, but so can their personalities. Intensive contact and interaction with persistent fellow students improve your own performance, and this effect even endures in subsequent semesters.

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
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.

Solar activity reconstructed over a millennium
Solar activity reconstructed over a millennium
An international team of researchers led by ETH Zurich has reconstructed solar activity back to the year 969 using measurements of radioactive carbon in tree rings. Those results help scientists to better understand the dynamics of the sun and allow more precise dating of organic materials using the C14 method.
