Protective factor against psychological trauma
The endogenous regulation of a specific gene is associated with a reduced risk of developing post-traumatic stress disorder following a terrifying experience. In particular, traumatic memories of the experience are less severe. Researchers from the University of Basel have reported these findings in the scientific journal PNAS.

Bringing computational music analysis beyond the traditional canon
Bringing computational music analysis beyond the traditional canon
Scientists in EPFL's Digital and Cognitive Musicology Lab (DCML), led by Martin Rohrmeier, have used data science and statistical techniques to characterize the musical style of choro, a primarily instrumental genre from Brazil, for the very first time. The study , which was recently published in the Journal of New Music Research , identifies key stylistic traits from some 300 pieces of choro music, providing an unprecedented empirical analysis of the harmony and form of the genre, which emerged in 19 th century Brazil and is still popular today.

Even small-scale solutions are affordable
Even small-scale solutions are affordable
How should Europe organise its renewable energy supply network - on a continental, national or regional level? It's a controversial issue. A Swiss-German research team has analysed the costs and technical feasibility of supply networks of various sizes. The European Union aims to achieve climate neutrality by 2050, and is relying largely on renewable electricity to reach this goal.

How a protein stops cells from attacking their own DNA
How a protein stops cells from attacking their own DNA
Scientists at EPFL have demonstrated the mechanism that allows cells to fight off viral DNA without triggering an immune response against their own genetic material. Viruses multiply by injecting their DNA into a host cell. Once it enters the intracellular fluid, this foreign material triggers a defense mechanism known as the cGAS-STING pathway.

Restoration helps forests recover faster
Restoration helps forests recover faster
Actively restored forests recover above ground biomass faster than areas left to regenerate naturally after being logged, according to a long-term study on Borneo lowland rainforest led by the University of Dundee, Aberdeen and ETH Zurich.  The rainforests of Southeast Asia are among the fastest declining tropical ecosystems worldwide.

Uranium reveals its true nature
Uranium reveals its true nature
Scientists have made a significant discovery in how nanoscale minerals form naturally, including the way in which they transition from a soluble to a solid state. Their findings could be used to inform radioactive waste management. Most people are familiar with uranium as a fuel for nuclear power plants.

Syphilis May Have Spread through Europe before Columbus
Syphilis May Have Spread through Europe before Columbus
Columbus brought syphilis to Europe - or did he? A recent study conducted at the University of Zurich now indicates that Europeans could already have been infected with this sexually transmitted disease before the 15th century. In addition, researchers have discovered a hitherto unknown pathogen causing a related disease.

The (neuro)science of getting and staying motivated
Neuroscientists at EPFL and the University of Edinburgh have discovered that the degree of motivation and the stamina to keep it up depends on the ratio between the neurotransmitters glutamine and glutamate in the nucleus accumbens of the brain. There is no question that motivation is one of the hardest and yet important factors in life.

Trustful Collaboration Critical for Outcome of Therapy
Trustful Collaboration Critical for Outcome of Therapy
A trusting therapeutic relationship and outcome-oriented collaboration between therapist and patient are critical for the successful treatment of mental illness. And it pays to start early in therapy, a series of meta-studies by a task force of the American Psychological Association (APA) led by UZH psychology professor Christoph Flückiger shows.

COVID-19, and the pressure to emulate
A surprising finding emerges from observing how different countries, confronted with different conditions and different epidemiological circumstances, have acted against the spread of COVID-19: the same restrictive policies, instead of spreading gradually across the various countries, have been adopted more or less at the same time.

New device delivers single cells in just one click
EPFL spin-off SEED Biosciences has developed a pipetting robot that can dispense individual cells one by one. Their innovation allows for enhanced reliability and traceability, and can save life-science researchers time and money. The engineers at SEED Biosciences, an EPFL spin-off, have come up with a unique pipetting robot that can isolate single cells with the push of a button - without damaging the cells.

Using air to amplify light
In a promising breakthrough for the future of communications, EPFL researchers have developed a technology that can amplify light in the latest hollow-core optical fibers. "The idea had been going around my head for about 15 years, but I never had the time or the resources to do anything about it." But now Luc Thévenaz, the head of the Fiber Optics Group in EPFL's School of Engineering, has finally made it happen: his lab has developed a technology to amplify light inside the latest hollow-core optical fibers.

A wound dressing that kills bacteria
A wound dressing that kills bacteria
In order to combat bacterial wound infections, Empa researchers have developed cellulose membranes equipped with antimicrobial peptides. Initial results show: The skin-friendly membranes made of plant-based materials kill bacteria very efficiently. If germs invade a wound, they can trigger a long-lasting infection that may fail to heal or even spread throughout the body, leading to life-threatening blood poisoning (sepsis).

New microscopes to unravel the mysteries of brain organization
Researchers around the world share their stunning images and insights: The open source mesoSPIM Initiative The secret of capturing exquisite brain images with a new generation of custom-built microscopes is revealed today . The new microscopes, known as mesoSPIMs, can image the minute detail of brain tissue down to individual neurons that are five times thinner than a human hair, and can uncover the 3D anatomy of entire small organs, faster than ever before.

Fireflies shed light on the function of mitochondria
The mitochondria provide energy for our cells, yet their role in many diseases is still poorly understood. Thanks to a bioluminescent molecule, scientists at EPFL can observe them at work in living mammals Tiny factories float inside our cells and provide them with almost all the energy they need: the mitochondria.

Deep learning and metamaterials make the invisible visible
By combining purpose-built materials and neural networks, researchers at EPFL have shown that sound can be used in high-resolution imagery. Imaging allows us to depict an object through far-field analysis of the lightand sound-waves that it transmits or radiates. The shorter the wave, the higher the image's resolution.

"Simulation microscope" examines transistors of the future
Since the discovery of graphene, two-dimensional materials have been the focus of materials research. Among other things, they could be used to build tiny, high-performance transistors. Researchers at ETH Zurich and EPF Lausanne have now simulated and evaluated one hundred possible materials for this purpose and discovered 13 promising candidates.

A highly light-absorbent and tunable material
A highly light-absorbent and tunable material
By layering different two-dimensional materials, physicists at the University of Basel have created a novel structure with the ability to absorb almost all light of a selected wavelength. The achievement relies on a double layer of molybdenum disulfide. The new structure's particular properties make it a candidate for applications in optical components or as a source of individual photons, which play a key role in quantum research.
