Portable device helps doctors diagnose sepsis faster
Portable device helps doctors diagnose sepsis faster
EPFL researchers have developed a highly sensitive and portable optical biosensor that stands to accelerate the diagnosis of fatal conditions like sepsis. It could be used by ambulances and hospitals to improve the triage process and save lives. Sepsis claims one life every four seconds. It is the primary cause of death in hospitals, and one of the ten leading causes of death worldwide.

Platelets instead of spheres make screens more economical
Platelets instead of spheres make screens more economical
ETH scientists have further developed QLED technology for screens. They have produced light sources that for the first time emit high-intensity light in only one direction. This reduces scattering losses, which makes the technology extremely energy efficient. QLED screens have been on the market for a few years now.

Interstellar journey of life's building block phosphorus unveiled
Interstellar journey of life’s building block phosphorus unveiled
Phosphorus, present in our DNA and cell membranes, is an essential element for life. But how it became available on the early Earth when life appeared here about 4 billion years ago is something of a mystery. For the first time, astronomers - among them researchers from the University of Bern - have now been able to show that molecules with phosphorus are formed in star-forming regions and probably came to Earth with comets.

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.

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.

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.
