Machine keeps human livers alive for one week outside of the body
A team of researchers has developed a machine that repairs injured human livers and keeps them alive outside the body for one week. This breakthrough may increase the number of available organs for transplantation saving many lives of patients with severe liver diseases or cancer. Until now, livers could be stored safely outside the body for only a few hours.

Reducing the risk of blood clots in artificial heart valves
Reducing the risk of blood clots in artificial heart valves
People with mechanical heart valves need blood thinners on a daily basis, because they have a higher risk of blood clots and stroke. Researchers at the ARTORG Center of the University of Bern, Switzerland, now identified the root cause of blood turbulence leading to clotting. Design optimization could greatly reduce the risk of clotting and enable these patients to live without life-long medication.

An 18-carat gold nugget made of plastic
ETH researchers have created an incredibly lightweight 18-carat gold, using a matrix of plastic in place of metallic alloy elements. Lovers of gold watches and heavy jewellery will be thrilled. The objects of their desire may someday become much lighter, but without losing any of their glitter. Especially with watches, a small amount of weight can make all the difference.

Unexpected twist in a quantum system
Unexpected twist in a quantum system
Physicists at ETH Zurich have observed a surprising twist in a quantum system caused by the interplay between energy dissipation and coherent quantum dynamics. To explain it, they found a concrete analogy to mechanics. "No scientist thinks in formulae", Albert Einstein allegedly once told his colleague Leopold Infeld.

Water governance: could less sometimes be more?
Water governance: could less sometimes be more?
Researchers from UNIGE and UNIL analysed water governance in six European countries from 1750 onwards. They demonstrated that there has been an inflationary trend in the number of regulations, and that - far from improving the situation - this has led to serious malfunctions in the system. The use of environmental resources has been regulated for centuries with the aim of improving the management and behaviour of private and public actors on an on-going basis.

Improved Functioning of Diverse Landscape Mosaics
Improved Functioning of Diverse Landscape Mosaics
It is well-established that biodiverse ecosystems generally function better than monocultures. Ecologists at the University of Zurich have now shown that the same is true on a larger scale: Having a mix of different land-covers including grassland, forest, urban areas and water bodies improves the functioning and stability of a landscape - irrespective of the plant species diversity, region and climate.

Bandage material helps stop bleeding without adhering to the wound
Bandage material helps stop bleeding without adhering to the wound
Researchers from ETH Zurich and the National University of Singapore have developed a new kind of bandage that helps blood to clot and doesn't stick to the wound. This marks the first time that scientists have combined both properties in one material. "We did not actually plan this, but that is just how science works sometimes: you start researching one thing and end up somewhere else," says ETH Professor Dimos Poulikakos.

Indeterminist physics for an open world
Indeterminist physics for an open world
A physicist suggests that the mathematical language spoken by classical physics should be changed to make room for indeterminism and an open future. Classical physics is characterised by the precision of its equations describing the evolution of the world as determined by the initial conditions of the Big Bang - meaning there is no room for chance.

Reducing human-induced earthquake risk
Reducing human-induced earthquake risk
Researchers at EPFL and the Swiss Federal Office of Energy have devised strategies for reducing the earthquake risk associated with geothermal energy, CO2 storage and other human activities happening deep underground. Although most earthquakes are attributable to natural causes, some are triggered - directly or indirectly - by human activity.

Fingerprint of climate change detected in daily weather
Fingerprint of climate change detected in daily weather
Climate researchers can now detect the fingerprint of global warming in daily weather observations at the global level. They are thus amending a long-established paradigm: weather is not climate ' but climate change can now be detected in daily weather. This research was carried out by ETH Zurich and the Swiss Data Science Center, co-directed by EPFL.

Biodegradable bridges
Globe magazine , News By: Samuel Schlaefli Researchers are looking into new materials to lay the foundations for living structures that respond to their environment. They aim to create self-sustaining infrastructures that can monitor their condition and even repair themselves. When Eleni Chatzi is not busy reading technical papers about vibrating bridges, smart infrastructures and data-driven engineering, she enjoys immersing herself in science fiction novels.

Climate signals detected in global weather
Searched for and found: climate researchers can now detect the fingerprint of global warming in daily weather observations at the global scale. They are thus amending a long-established paradigm: weather is not climate - but climate change can now be detected in daily weather. In October this year, weather researchers in Utah measured the lowest temperature ever recorded in the month of October in the US (excluding Alaska): -37.1°C.

Capturing CO2 from trucks and reducing their emissions by 90%
Capturing CO2 from trucks and reducing their emissions by 90%
Researchers at EPFL have patented a new concept that could cut trucks' CO2 emissions by almost 90%. It involves capturing CO2 within the exhaust system, converting it into a liquid and storing it on the vehicle. The liquid CO2 would then be delivered to a service station and where it will be turned back into fuel using renewable energy.

A new method for boosting the learning of mathematics
UNIGE researchers oversaw a new system of maths learning whose purpose is to promote the use of arithmetic formulas at an early age. After a year, they observed a leap in students' performance. How can mathematics learning in primary school be facilitated? A recent study conducted by the University of Geneva (UNIGE), Switzerland, had shown that our everyday knowledge strongly influences our ability to solve problems, sometimes leading us into making errors.

Identifications of neurons responsible for rapid eye movements (REM) during sleep
Why do we move our eyes fast in the paradoxical sleep - in that sleep phase, in which most dreams take place? The secret is not yet fully aired, but we are on his track: A team of researchers has identified the nerve cells behind this curious phenomenon. REM - Rapid Eye Movement - is not only the name of a successful American rock band, but also and not least a characteristic eye movement in paradoxical sleep, so in the stage with high dream activity.

Bark Beetles Control Pathogenic Fungi
Bark Beetles Control Pathogenic Fungi
Pathogens can drive the evolution of social behaviour in insects. This is shown by researchers from Bern and Würzburg for ambrosia beetles. Ants and honeybees share nests of hundreds or thousands of individuals in a very small space. Hence the risk is high that infectious diseases may spread rapidly.
