Nanodevices can produce energy from evaporating tap or seawater
Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential. Evaporation is a natural process so ubiquitous that most of us take it for granted.

Deciphering a dance of electrons and water molecules
Deciphering a dance of electrons and water molecules
A research project at EPFL succeeded in decoding the complex dance of electrons in water, a major step in understanding a critical process of many chemical phenomena, and that might be the first step to improving energy conversion technologies. Water, the cradle of life on Earth, is not just a passive backdrop but actively participates in the chemical ballet of life.

The baritone of Red Giants refines cosmic distance measurements
The baritone of Red Giants refines cosmic distance measurements
A fresh look at red giant stars offers key insights into cosmic distance measurements and a way to measure the Universe's expansion with the highest accuracy. In a constantly expanding universe, measuring cosmic distances is like trying to find a reliable ruler in a vast, ever-stretching fabric. One tool that astrophysicists use is the Hubble constant, (H0), which measures how fast the Universe is expanding and sets the age and observable size of the Universe.

A new ion trap for larger quantum computers
A new ion trap for larger quantum computers
Researchers at ETH have managed to trap ions using static electric and magnetic fields and to perform quantum operations on them. In the future such traps could be used to realize quantum computers with far more quantum bits than have been possible up to now. The energy states of electrons in an atom follow the laws of quantum mechanics: they are not continuously distributed but restricted to certain well-defined values - this is also called quantisation.

A new theoretical development clarifies water's electronic structure
A new theoretical development clarifies water's electronic structure
Scientists at EPFL have decoded the electronic structure of water, opening up new perspectives for technological and environmental applications. There is no doubt that water is significant. Without it, life would never have begun, let alone continue today - not to mention its role in the environment itself, with oceans covering over 70% of Earth.

DIY structured-illumination microscope
DIY structured-illumination microscope
Scientists at EPFL have published a guide to building an add-on that turns a standard optical microscope into an instrument capable of producing super resolution, 3D images of cells, organoids, and embryos. For hundreds of years, the optical microscope was the only tool available to scientists wanting to study the movement of cells, bacteria and yeast.

Cause of clogged hypodermic needles discovered
Cause of clogged hypodermic needles discovered
Researchers at the Paul Scherrer Institute PSI and the ANAXAM technology transfer center have used neutron and synchrotron imaging to determine the conditions under which pre-filled syringes become blocked. In very rare cases, the needles of prefilled syringes may become blocked. This can have potentially detrimental consequences for patients if their medication does not enter the body or the dosage is too low.

Nanotweezers accelerate phage therapy
Scientists at EPFL have developed a game-changing technique that uses light to manipulate and identify individual bacteriophages without the need for chemical labels or bioreceptors, potentially accelerating and revolutionizing phage-based therapies that can treat antibiotic-resistant bacterial infections.

It's the spin that makes the difference
It’s the spin that makes the difference
Biomolecules such as amino acids and sugars occur in two mirror-image forms - in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers at Empa and Forschungszentrum Jülich in Germany have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.

A ’quantum leap’ at room temperature
Scientists have achieved a milestone by controlling quantum phenomena at room temperature. Image: Conceptual art of the operating device, consisting of a nanopillar-loaded drum sandwiched by two periodically segmented mirrors, allowing the laser light to strongly interact with the drum quantum mechanically at room temperature.

Visualising multiple sclerosis with a new MRI procedure
Visualising multiple sclerosis with a new MRI procedure
The loss of myelin sheaths in the brain is a hallmark of multiple sclerosis. Researchers at ETH Zurich have now developed an MRI method that maps the condition of this nerve insulation layer more accurately than before. Multiple sclerosis (MS) is a neurological disease that usually leads to permanent disabilities.

How to make bright quantum dots even brighter
How to make bright quantum dots even brighter
Researchers at Empa and ETH have developed methods for making perovskite quantum dots faster and more efficient emitters, thereby significantly improving their brightness. This is relevant for applications in displays as well as in quantum technologies. Quantum dots are a kind of artificial atom: just a few nanometres in size and made of semiconductor materials, they can emit light of a specific colour or even single photons, which is important for quantum technologies.

Turning glass into a 'transparent' light-energy harvester
Turning glass into a ’transparent' light-energy harvester
Physicists propose a novel way to create photoconductive circuits, where the circuit is directly patterned onto a glass surface with femtosecond laser light. The new technology may one day be useful for harvesting energy, while remaining transparent to light and using a single material. What happens when you expose tellurite glass to femtosecond laser light?

A new state in a quantum material
A new state in a quantum material
Scientists at EPFL break new ground in quantum physics, revealing a mysterious and unique behavior in a quantum magnetic material and hinting at future tech breakthroughs. In the mysterious world of quantum materials, things don't always behave as we expect. These materials have unique properties governed by the rules of quantum mechanics, which often means that they can perform tasks in ways traditional materials cannot - like conducting electricity without loss - or having magnetic properties that may prove useful in advanced technologies.

Moon rocks with unique dust found
A research team from the University of Münster has discovered for the first time meter-sized rocks on the surface of the moon that are covered in dust and presumably have unique properties - magnetic anomalies, for example. The findings help to understand the processes that form and change the lunar crust.

Mass-producible miniature quantum memory
Researchers at the University of Basel have built a quantum memory element based on atoms in a tiny glass cell. In the future, such quantum memories could be mass-produced on a wafer. It is hard to imagine our lives without networks such as the internet or mobile phone networks. In the future, similar networks are planned for quantum technologies that will enable the tap-proof transmission of messages using quantum cryptography and make it possible to connect quantum computers to each other.

Bridging light and electrons
Researchers at EPFL and Max Plank have merged nonlinear optics with electron microscopy, unlocking new capabilities in material studies and the control of electron beams. When light goes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of an entire field of study called "nonlinear optics", which is now integral to technological and scientific advances from laser development and optical frequency metrology, to gravitational wave astronomy and quantum information science.

Laser additive manufacturing: listening for defects as they happen
Researchers from EPFL have resolved a long-standing debate surrounding laser additive manufacturing processes with a pioneering approach to defect detection. The progression of laser additive manufacturing - which involves 3D printing of metallic objects using powders and lasers - has often been hindered by unexpected defects.
