Making it easier to differentiate mirror-image molecules
Making it easier to differentiate mirror-image molecules
Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human body. Researchers from Paul Scherrer Institute PSI, EPF Lausanne (EPFL), and the University of Geneva describe the new method in the scientific journal Nature Photonics .

The Higgs boson, ten years after its discovery
Geneva, 4 July 2022. Ten years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the Higgs boson predicted by the Standard Model of particle physics. The discovery was a landmark in the history of science and captured the world's attention.

Quantum network nodes with warm atoms
Quantum network nodes with warm atoms
Communication networks need nodes at which information is processed or rerouted. Physicists at the University of Basel have now developed a network node for quantum communication networks that can store single photons in a vapor cell and pass them on later. In quantum communication networks, information is transmitted by single particles of light (photons).

Boosting light power revolutionizes communications and autopilot
Boosting light power revolutionizes communications and autopilot
Scientists have built a compact waveguide amplifier by successfully incorporating rare-earth ions into integrated photonic circuits. The device produces record output power compared to commercial fiber amplifiers, a first in the development of integrated photonics over the last decades. Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical signal power in optical fibers, often used in long-distance communication fiber optic cables and fiber-based lasers.

Twin photons from unequal sources
Twin photons from unequal sources
Identical light particles (photons) are important for many technologies that are based on quantum physics. A team of researchers from Basel and Bochum has now produced identical photons with different quantum dots - an important step towards applications such as tap-proof communications and the quantum internet.

The Sun is spinning round again
The Sun is spinning round again
An international team led by astronomers from the UNIGE has succeeded in developing a model to solve part of the 'solar problem'. All was amiss with the Sun! In the early 2000s, a new set of data brought down the chemical abundances at the surface of the Sun, contradicting the values predicted by the standard models used by astrophysicists.

A new calculation for predicting fusion energy
A new calculation for predicting fusion energy
Physicists at EPFL, within a large European collaboration, have revised one of the fundamental laws that has been foundational to plasma and fusion research for over three decades, even governing the design of megaprojects like ITER. The update shows that we can actually safely use more hydrogen fuel in fusion reactors, and therefore obtain more energy than previously thought.

Black holes as noise traps
Black holes as noise traps
Anyone who lives in an old building with wooden floors knows the problem: Even if the neighbors from above glide across the floor with graceful elegance, it sounds as if you were living under a bowling alley. Impact sound is a challenge even for the most modern wooden buildings. Scientists at Empa are now tinkering with a solution.

Quantum one-way street in topological insulator nanowires
Quantum one-way street in topological insulator nanowires
Very thin wires made of a topological insulator could enable highly stable qubits, the building blocks of future quantum computers. Scientists see a new result in topological insulator devices as an important step towards realizing the technology's potential. An international group of scientists have demonstrated that wires more than 100 times thinner than a human hair can act like a quantum one-way street for electrons when made of a peculiar material known as a topological insulator.

Single photon emitter takes a step closer to quantum tech
Single photon emitter takes a step closer to quantum tech
To get closer to quantum technology we need to develop non-classical light sources that can emit a single photon at a time and do so on demand.

Glowing glass droplets on the ISS
Glowing glass droplets on the ISS
Together with researchers from Ulm and Neuchâtel, Empa will soon be studying material samples on the ISS. The material in question are super-hard and corrosion-resistant alloys of palladium, nickel, copper and phosphorus - also known as "metallic glasses". A high-tech company from La Chaux-de-Fonds, which produces materials for the watch industry, is also involved.

Imaging chemical kinetics at liquid-liquid interfaces
Imaging chemical kinetics at liquid-liquid interfaces
Scientists led by EPFL have developed a new method to measure chemical kinetics by imaging progress of a reaction at a liquid-liquid interface embedded in a laminar-flow liquid microjet. This method is ideal for studies of dynamics on the sub-millisecond timescale, which is very difficult to do with current applications.

Revolutionary images of the birth of crystals
Revolutionary images of the birth of crystals
A team from the UNIGE has succeeded in visualizing crystal nucleation - the stage that precedes crystallization - that was invisible until now. At the interface between chemistry and physics, the process of crystallization is omnipresent in nature and industry. It is the basis for the formation of snowflakes but also of certain active ingredients used in pharmacology.

From cell fat to cell fate
From cell fat to cell fate
A cell's production of fat molecules can be a key factor in determining what that cell will become, show scientists at EPFL. How does a cell -decide- what type of cell to become? The question of -cell fate- has been explored for decades now, especially in the context of stem cell biology, but there are still gaps in our understanding.

Golden wedding for molecules
Golden wedding for molecules
Chemical syntheses in liquids and gases take place in three-dimensional space. Random collisions between molecules have to result in something new in an extremely short time. But there is another way: on a gold surface under ultrahigh vacuum conditions, molecules lying still next to each other can be made to combine - even those that would never want to react with each other in a liquid.

Solar nanowire-nanotube filter offers easy access to clean water
Solar nanowire-nanotube filter offers easy access to clean water
Scientists at EPFL have developed a highly efficient water purification filter that uses only solar power. The prototype can supply clean drinking water even at remote places to small populations and can be easily scaled-up. Even today, clean water is a privilege for many people across the world. According to the World Health Organization (WHO), at least 1.8 billion people consume water contaminated with feces, and by 2040, a large portion of the world will endure water stress because of insufficient resources of drinking water.

A look into the magnetic future
Researchers at PSI have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes. This view into processes that take place within so-called artificial spin ice could play an important role in the development of novel high-performance computers.
