To uncover the relationship between variation in genes and phenotypic diversity, geneticists use a set of fully sequenced fruit-fly genomes. But little is known about the variation in the mitochondrial genome, for which mutations are linked to an array of diseases. Now, EPFL scientists have created a high-resolution map of mitochondrial DNA variants in the fruit fly, connecting mitochondrial genes to metabolic traits and diseases.

Graphene, a two-dimensional structure made of carbon, is a material with excellent mechanical, electronic and optical properties. However, it did not seem suitable for magnetic applications. Together with international partners, Empa researchers have now succeeded in synthesizing a unique nanographene predicted in the 1970s, which conclusively demonstrates that carbon in very specific forms has magnetic properties that could permit future spintronic applications.

A research team with members from ETH Zurich has discovered a new method for turning nearly any object into a data storage unit. This makes it possible to save extensive data in, say, shirt buttons, water bottles or even the lenses of glasses, and then retrieve it years later. The technique also allows users to hide information and store it for later generations.

Some of the Earth's building material was stardust from red giants, researchers from ETH Zurich have established. They can also explain why the Earth contains more of this stardust than the asteroids or the planet Mars, which are farther from the sun. Around 4.5 million years ago, an interstellar molecular cloud collapsed.

Researchers at EPFL have discovered that the viscosity of solutions of electrically charged polymers dissolved in water is influenced by a quantum effect. This tiny quantum effect influences the way water molecules interact with one another. Yet, it can lead to drastic changes in large-scale observations.

Becoming a Swiss citizen promotes immigrants' integration into Swiss society. After naturalizing, new citizens' annual earnings increased by an average of CHF 5,000 compared to their unnaturalized peers. This boost benefits the new citizens, the state, and society as a whole. What is the best way to further immigrant integration? This has long been a topic of discussion among specialists.

Researchers at EPFL's Computational Solid Mechanics Laboratory and the Weizmann Institute of Science have modeled the onset of slip between two bodies in frictional contact. Their work, a major step forward in the study of frictional rupture, could give us a better understanding of earthquakes - including how far and fast they travel.

The Defitech Foundation has teamed up with EPFL, CHUV and UNIL to widen access to the groundbreaking neurotechnology developed under the 2018 STIMO study, which allowed paraplegic patients to walk again. Their aim is also to develop new neurosurgical treatments for people suffering from Parkinson's disease or from neurological disorders following a head injury or stroke.

Thanks to a newly developed laser spectrometer, Empa researchers can for the first time show which processes in grassland lead to nitrous oxide emissions. The aim is to reduce emissions of this potent greenhouse gas by gaining a better understanding of the processes taking place in the soil. Nitrous oxide (N2O, also known as laughing gas) is one of the most important greenhouse gases.

When two individuals from different species mate, the offspring is known as a hybrid. As a result of the genomes being mixed, sometimes phenotypes are produced that deal with new environmental conditions better than the two parent species. Very often, hybrids are not able to reproduce, but there are quite a number of exceptions to this, including the cichlids.

Scientists from ETH Zurich and the University of Basel's Biozentrum have shown that chaperone proteins dynamically bind to the Parkinson protein -synuclein. If this interaction is disturbed, it leads to cell damage and the formation of aggregates typical for the disease. Parkinson's disease is characterised by the progressive death of nerve cells in the brain.

EPFL researchers have developed Big Data tools for identifying new gene functions. The work identifies millions of connections between genes and their functions, and can facilitate the development of precision medicine. Genes are the functional units of heredity, and the understanding of gene function is the major focus of biomedical research, serving as the basis of precision medicine.

A material that thickens when you pull on it seems to contradict the laws of physics. However, the so-called auxetic effect, which also occurs in nature, is interesting for a number of applications. A new Empa study recently published in "Nature Communications" shows how this amazing behavior can be improved - and even used to treat injuries and tissue damage.

EPFL scientists have developed a computational method modeling and designing protein allostery that allows the accurate and rational engineering and even re-purposing of cell receptors. The method can be a significant tool for drug development. Called the "second secret of life", allostery is one of the most fundamental processes of biology and has been a central focus among scientists across the life sciences spectrum, from fundamental biology to drug development.

An EPFL Bachelor's student has solved a mystery that has puzzled scientists for 100 years. He discovered why gas bubbles in narrow vertical tubes seem to remain stuck instead of rising upwards. According to his research and observations, an ultra-thin film of liquid forms around the bubble, preventing it from rising freely.

Patient safety in intensive care units could be significantly improved if false alarms could be greatly reduced and critical complications such as epileptic seizures could be predicted. This is where the "ICU Cockpit" project of the National Research Programme "Big Data" (NRP 75) comes in: The large amounts of data from intensive care medicine will be used to develop procedures for early warning systems and therapeutic recommendations.

If one turns a stone over in a river or stream, it swarms with tiny animals: caddisflies, water beetles, freshwater shrimp, and snails. The invertebrates living on the beds of water bodies that can be seen with the naked eye, called macroinvertebrates, are rather unimposing, but for science and the protection of surface waters they are of great importance.

ETH Zurich researchers are reexamining the causes of soil erosion around the world - and have found that countries themselves have a surprisingly strong influence on their soil. This country effect was previously undetected. Soil erosion is a global problem that threatens food security and the functioning of ecosystems.

Physicists from Switzerland, Germany, and France have found that large-amplitude acoustic waves, launched by ultrashort laser pulses, can dynamically manipulate the optical response of semiconductors. One of the main challenges in materials science research is to achieve high tunability of the optical properties of semiconductors at room temperature.
