From gigantic planets to tiny images
From gigantic planets to tiny images
From the smallest ever printed colour image and the world's largest plant seeds to the darkest matter in the infinite expanse of the universe - over the past year, ETH research has focussed on all animate and inanimate aspects of the natural world, presenting fascinating results and ingenious inventions.

Faster entanglement of distant quantum dots
Faster entanglement of distant quantum dots
Entanglement between distant quantum objects is an important ingredient for future information technologies. Researchers at the ETH have now developed a method with which such states can be created a thousand times faster than before. In many future information and telecommunication technologies, a remarkable quantum effect called entanglement will likely play an important role.

Spintronics, low-energy electricity take a step closer
Spintronics, low-energy electricity take a step closer
18.12.15 - EPFL scientists have discovered a new topological insulator that could be used in future electronic technologies. Topological insulators are recently discovered materials that differ from the familiar insulators and semiconductors in many ways. While topological insulators are fascinating for fundamental physics, they could one day enable electricity with less energy loss, spintronics, and perhaps even quantum computing.

Diagnostics with birefringence
Diagnostics with birefringence
ETH researchers led by Raffaele Mezzenga have developed a new diagnostic method. It is based on Birefringence, the ability of substances to change the polarisation state of light. With this method, doctors around the world can easily, rapidly and reliably detect malaria, Ebola or HIV to name only a few.

Successful launch of LISA Path-finder
Successful launch of LISA Path-finder
After the successful lift-off of the Vega rocket in French Guiana, the LISA Pathfinder satellite uncoupled from its booster rocket at approximately 7.00 a.m. this morning. The satellite will spend the next 9 months floating in space. There it will enable scientists to test key measurement techniques for the detection of gravitational waves, which Albert Einstein predicted about 100 years ago in his general theory of relativity.

Surprising discovery of a new particle
Surprising discovery of a new particle
Studying peculiar properties of a long known metallic material researchers have chanced upon a new particle. It is related to the so-called Weyl fermions that the mathematician Hermann Weyl predicted almost ninety years ago. Weyl had overlooked the particle, which could have interesting applications in electronics.

Using light-force to study single molecules
Using light-force to study single molecules
23.11.15 - Scientists at EPFL show how a light-induced force can amplify the sensitivity and resolution of a technique used to study single molecules. When it comes to studying single molecules, scientists use a powerful technique called "surface-enhanced Raman scattering" (SERS). An extremely sensitive tool, SERS detects the vibrations within the atoms of the illuminated molecule as a change in light color.

3D-mapping a new drug-delivery tool
3D-mapping a new drug-delivery tool
17.11.15 - Scientists from EPFL and Nestlé have developed a new method that can "see" inside dispersed cubosomes (dispersed cubic liquid crystalline phases) with unprecedented detail. The breakthrough can help to improve their design significantly for better drug or nutrient delivery. Cubosomes are small biological "capsules" that can deliver molecules of nutrients or drugs with high efficiency.

“It’s scarcely possible to grasp intuitively”
In November 1915, Albert Einstein presented four seminal publications that laid the foundation for the general theory of relativity. A symposium at ETH Zurich celebrates its 100th anniversary from 12 to 14 November. ETH News: Hans-Rudolf Ott, you are one of the organisers of the symposium on 100 years of the general theory of relativity.

Increasing vitamin D supplementation
Increasing vitamin D supplementation
Elderly women should take in more vitamin D than previously recommended during the winter months. Osteoporosis is one of the chief reasons why the elderly often suffer broken bones from relatively minor injuries.

Monitoring critical blood levels in real time in the ICU
Monitoring critical blood levels in real time in the ICU
23.10.15 - For patients in intensive care, knowing how much glucose, lactate and other substances are in the blood is a question of life or death. EPFL has developed a miniaturized microfluidic device that will allow medical staff to monitor these levels in real time and react more quickly.

Looking at the earliest galaxies
22.10.15 - An international team of astronomers led by EPFL have discovered over 250 of the universe's earliest galaxies. This sample includes the faintest and smallest of the first-generation dwarf galaxies to be discovered, and offers important clues about the nature of the early universe.

3D Structure of a Protein Complex Important for Immune Response
3D Structure of a Protein Complex Important for Immune Response
Our innate immune system rapidly eliminates invading pathogens. When a pathogen is detected in the body, the "inflammasome" protein complex initiates the defense response of the immune cells. By combining two high-resolution methods, researchers from the University of Basel's Biozentrum have now determined the atomic structure of an important part of the inflammasome.

A resonator for electrons
A resonator for electrons
Resonators are an important tool in physics. The curved mirrors inside the resonators usually focus light waves that act, for instance, on atoms. Physicists at ETH Zurich have now managed to build a resonator for electrons and to direct the standing waves thus created onto an artificial atom. More than two thousand years ago the Greek inventor and philosopher Archimedes already came up with the idea of using a curved mirror to reflect light in such a way as to focus it into a point - legend has it that he used this technique to set fire to the ships of the Roman enemies.

Tiny magnets mimic steam, water and ice
Tiny magnets mimic steam, water and ice
Researchers at the Paul Scherrer Institute (PSI) created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state.

The key to charging a lithium-ion battery rapidly
The key to charging a lithium-ion battery rapidly
Researchers reveal the reasons for these properties in a new study. During the charge and discharge process for this kind of battery, lithium ions need to move between the two electrodes. As it turns out, the rapid charging of these batteries is down to the fact that, at a higher charging voltage, the lithium ions are distributed evenly across the volume of the particles that make up the battery electrode, which contains lithium.

ATLAS and CMS experiments shed light on Higgs properties
ATLAS and CMS experiments shed light on Higgs properties
Three years after the announcement of the discovery of a new particle, the so-called Higgs boson, the ATLAS and CMS Collaborations present for the first time combined measurements of many of its properties, at the third annual Large Hadron Collider Physics Conference (LHCP 2015). By combining their analyses of the data collected in 2011 and 2012, ATLAS and CMS draw the sharpest picture yet of this novel boson.
