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.

A major proof of concept for brain simulation
08.10.15 - An international team led by EPFL scientists have completed a first draft computer reconstruction of a piece of the neocortex. The electrical behavior of the virtual brain tissue was simulated on supercomputers and found to match the behavior observed in a number of experiments on the brain.

Mysterious structures observed
Mysterious structures observed
A research team has observed structures racing out from the centre of a young star's debris disk at high speeds. It is still unclear what causes the phenomenon. "We were speechless when we saw the image for the first time in the control room at the observatory in Chile," remembers Christian Thalmann of the Institute for Astronomy at ETH Zurich, who is also a member of the National Centre of Competence in Research PlanetS and a Marie Curie fellow.

Trade in invasive plants is blossoming
Trade in invasive plants is blossoming
Every day, hundreds of different plant species - many of them listed as invasive - are traded online worldwide on auction platforms. This exacerbates the problem of uncontrollable biological invasions. Goldenrod, Himalayan balsam, Chinese windmill palm: three plants, one problem. All are native to continents other than Europe, but were introduced to Switzerland as garden or ornamental plants.

Real-time analysis of metabolic products
Real-time analysis of metabolic products
Biologists at ETH Zurich have developed a method that, for the first time, makes it possible to measure concentration changes of several hundred metabolic products simultaneously and almost in real time. The technique could inspire basic biological research and the search for new pharmaceutical agents.

Biomimetic dental prosthesis
Biomimetic dental prosthesis
ETH material researchers are developing a procedure that allows them to mimic the complex fine structure of biological composite materials, such as teeth or seashells. They can thus create synthetic materials that are as hard and tough as their natural counterparts. Cross section of the artificial tooth under an electron microscope: Ceramic platelets in the enamel are orientated vertically.

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.

Adapting electricity demand to production. Not the other way around
04.09.15 - Instead of aligning energy production with consumption, wouldn't it be possible to make consumption adapt to the intermittency of renewable energies? François Vuille, director of development at the Energy Center, shares his thoughts.

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.

Precise comparison of light nuclei and antinuclei
Precise comparison of light nuclei and antinuclei
The ALICE experiment at the Large Hadron Collider (LHC) at CERN has made a precise measurement of the difference between ratios of the mass and electric charge of light nuclei and antinuclei. The result, published today , confirms a fundamental symmetry of nature to an unprecedented precision for light nuclei.

The BASE experiment at CERN compares protons and antiprotons with high precision
The Baryon Antibaryon Symmetry Experiment (BASE ) at CERN 2 's Antiproton Decelerator (AD), reports the most precise comparison of the charge-to-mass ratio of the proton to that of its antimatter equivalent, the antiproton. The charge-to-mass ratio - an important property of particles - can be measured by observing the oscillation of a particle in a magnetic field.

New details of the transmission of stimuli in living organisms unveiled
Researchers unveil new details about how cells in a living being process stimuli. The study focuses on so-called G-proteins, which help transmit external stimuli that reach a cell into its interior. Using a technique developed at the Paul Scherrer Institute PSI, the study authors discovered which parts of the G-proteins are vital for their functioning.

CERNís LHCb experiment reports observation of exotic pentaquark particles
LHCb experiment at CERN's Large Hadron Collider has reported the discovery of a class of particles known as pentaquarks. "The pentaquark is not just any new particle," said LHCb spokesperson Guy Wilkinson. " It represents a way to aggregate quarks, namely the fundamental constituents of ordinary protons and neutrons, in a pattern that has never been observed before in over fifty years of experimental searches .

LHC experiments are back in business at a new record energy
Today, CERN 's Large Hadron Collider (LHC) started delivering physics data for the first time in 27 months. After an almost two year shutdown and several months re-commissioning, the LHC is now providing collisions to all of its experiments at the unprecedented energy of 13 TeV, almost double the collision energy of its first run.
