A nanoscale device that can see through walls
A nanoscale device that can see through walls
Researchers at EPFL have developed a nanodevice that operates more than 10 times faster than today's fastest transistors, and about 100 times faster than the transistors you have on your computers. This new device enables the generation of high-power terahertz waves. These waves, which are notoriously difficult to produce, are useful in a rich variety of applications ranging from imaging and sensing to high-speed wireless communications.

Chemistry: Access to forbidden rings
Chemistry: Access to forbidden rings
Researchers from the University of Geneva have developed a new method for creating chains of molecular rings with unparalleled sophistication. Cyclic molecules are everywhere, and everything around us stems from the way they are assembled: not just taste, colour and smell but also (for example) pharmaceutical drugs.

Solved: the mystery of the expansion of the universe
Solved: the mystery of the expansion of the universe
A researcher from the University of Geneva has solved a scientific controversy about the speed of the expansion of the universe by suggesting that it is not totally homogeneous on a large scale. The earth, solar system, entire Milky Way and the few thousand galaxies closest to us move in a vast "bubble" that is 250 million light years in diameter, where the average density of matter is half as large as for the rest of the universe.

Introducing the light-operated hard drives of tomorrow
Introducing the light-operated hard drives of tomorrow
What do you get when you place a thin film of perovkite material used in solar cells on top of a magnetic substrate? More efficient hard drive technology. EPFL physicist László Forró and his team pave the way for the future of data storage. "The key was to get the technology to work at room temperature," explains László Forró, EPFL physicist.

Solving problems of analytic continuation through machine learning
Solving problems of analytic continuation through machine learning
An EPFL student has shown how deep learning can be used to analytically connect digital simulations and experimental results more quickly and reliably than conventional methods. This work, which the student carried out for his semester project, was recently published in Physical Review Letters. It's not unusual for scientists to compare experimental results with the predictions made by theoretical models.

Tracking down the mystery of matter
Tracking down the mystery of matter
Researchers at the Paul Scherrer Institute PSI have measured a property of the neutron more precisely than ever before. In the process they found out that the elementary particle has a significantly smaller electric dipole moment than was previously assumed. With that, it has also become less likely that this dipole moment can help to explain the origin of all matter in the universe.

Tying up molecules as easily as you tie up your laces
Tying up molecules as easily as you tie up your laces
UNIGE researchers have succeeded in tying molecules together, thereby modifying their intrinsic mechanical properties. Knots are all around us: in computer cables, headphones and wires. But, although they can be a nuisance, they're also very useful when it comes to tying up your laces or when you go sailing.

Glass slides that stand to revolutionize fluorescence microscopy
Glass slides that stand to revolutionize fluorescence microscopy
EPFL scientists have developed a new type of microscope slide that can boost the amount of light in fluorescence microscopy by a factor of up to 25. These new slides can both amplify and direct light, making them ideal for applications ranging from early-stage diagnosis to the rapid archiving of pathology samples.

Short film of a magnetic nano-vortex
Short film of a magnetic nano-vortex
For the first time, researchers at the Paul Scherrer Institute PSI have recorded a "3D film" of magnetic processes on the nanometer scale. This reveals a variety of dynamics inside the material, including the motion of swirling boundaries between different magnetic domains. The insights were gained with a method newly developed at the Swiss Light Source SLS.

Time-resolved measurement in a memory device
Time-resolved measurement in a memory device
Researchers at ETH have measured the timing of single writing events in a novel magnetic memory device with a resolution of less than 100 picoseconds. Their results are relevant for the next generation of main memories based on magnetism. At the Department for Materials of the ETH in Zurich, Pietro Gambardella and his collaborators investigate tomorrow's memory devices.

Creating custom light using 2D materials
Researchers from the University of Geneva and the University of Manchester have discovered structures based on two-dimensional materials that emit tailor-made light in any colour you could wish for. Finding new semi-conductor materials that emit light is essential for developing a wide range of electronic devices.

A fast light detector made of two-dimensional materials
A fast light detector made of two-dimensional materials
Two research groups at ETH Zurich have joined forces to develop a novel light detector. It consists of two-dimensional layers of different materials that are coupled to a silicon optical waveguide. In the future, this approach can also be used to make LEDs and optical modulators. Fast and highly efficient modulators as well as detectors for light are the core components of data transmission through fibre optic cables.

New quasiparticle unveiled in room temperature semiconductors
New quasiparticle unveiled in room temperature semiconductors
Physicists from Switzerland and Germany have unveiled fingerprints of the long-sought particle known as Mahan exciton in the room temperature optical response of the popular methylammonium lead halide perovskites. The optical properties of semiconductors are governed by the so-called 'excitons', which are bound pairs of negative electrons and positive holes.

Bacteria under the microscope: a new growth model for tuberculosis
Bacteria under the microscope: a new growth model for tuberculosis
New research has shed light on how mycobacteria grow. This discovery could explain why some members of this family of single-celled organisms, which includes the bacillus that causes tuberculosis, can develop resistance to antibiotics For centuries, scientists have peered down the lens of a microscope and watched as bacteria - some circular, others rod-shaped - multiply before their eyes.

A novel formulation to explain heat propagation
A novel formulation to explain heat propagation
Researchers at EPFL and MARVEL have developed a novel formulation that describes how heat spreads within crystalline materials. This can explain why and under which conditions heat propagation becomes fluid-like rather than diffusive. Their equations will make it easier to design next-generation electronic devices at the nanoscale, in which these phenomena can become prevalent.

What if half of Switzerland's rooftops produced electricity?
Researchers at EPFL are assessing Switzerland's solar power potential. Their results show that photovoltaic panels could be installed on more than half of the country's 9.6 million rooftops. The resulting power would meet more than 40% of Swiss electricity demand. The widespread installation of photovoltaic panels on building rooftops could play an important role in Switzerland's transition to a low-carbon energy system.

Could resetting our internal clocks help control diabetes?
Could resetting our internal clocks help control diabetes?
Researchers from the University of Geneva and HUG were able to demonstrate the link between disturbances of the circadian clocks in pancreatic cells and type 2 diabetes, then to correct these disturbances. The circadian clock system (from Latin "circa diem", about a day) allows the organisms to anticipate periodical changes of geophysical time, and to adjust to these changes.

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.
