Machine keeps human livers alive for one week outside of the body
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.

Well-varnished violins play longer
Well-varnished violins play longer
Don't ever let a violin go without varnish, researchers advise, on the basis of a new study published in the journal "Scientific Reports". The scientists used neutron imaging to investigate what effects different coatings have on the wood of the instrument. Varnishing does in fact reliably protect against humidity, but it also influences the sound characteristics of the wood.

Cosmic magnifying glasses show faster expanding universe
Cosmic magnifying glasses show faster expanding universe
New measurements using gravitational lensing, an innovative method that EPFL researchers have been working on for many years, suggest the universe is expanding faster than previously thought. A team of astronomers using NASA's Hubble Space Telescope have announced that the universe is expanding faster than expected.

A neural network as an anchor point
A neural network as an anchor point
Quantum mechanics is a well-established theory, but at a macroscopic level it leads to intractable contradictions. Now ETH physicists are proposing to resolve the problem with the aid of neural networks. Necessity is the mother of invention.

Visualizing chemical reactions
Visualizing chemical reactions
Researchers at the joint EPFL-Empa lab in Sion have developed a reactor system and an analysis method that has allowed them to observe the real-time production of synthetic natural gas from CO2 and H2 for the first time. Infrared (IR) thermography is used to determine the temperature of humans and objects with high precision and without interfering with the system.

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.

Tiny pharmaceuticals in the environment
Tiny pharmaceuticals in the environment
Nanomedicine is making headways. However, the tiny nanoparticles that are being used as carriers for drugs could find their way into water, soil and air. Empa researchers are investigating potential risks. Fear is a bad counselor. In the comic book series "Asterix", the Gaul chief Vitalstatistix may be afraid that the sky may fall on his head.

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.
