Incorporating guanidinium into perovskite solar cells stabilizes their efficiency at 19% for 1000 hours under full-sunlight testing conditions. With the power-conversion efficiency of silicon solar cells plateauing around 25%, perovskites are now ideally placed to become the market's next generation of photovoltaics.

The years of careful planning and construction have paid off: At the newest large-scale research facility of the Paul Scherrer Institute PSI - the free-electron X-ray laser SwissFEL - the first experiment has been carried out successfully. With that, two goals have been achieved: First, a new scientific result is already expected.

Using a bioinformatics and experimental approach, scientists at EPFL have found that rendering mitochondria resistant to damage can halt diseases caused by amyloid toxicity, such as Alzheimer's disease. Alzheimer's disease is the most common form of dementia and neurodegeneration worldwide. A major hallmark of the disease is the accumulation of toxic plaques in the brain, formed by the abnormal aggregation of a protein called beta-amyloid inside neurons.

The Internet would be nothing without hyperlinks. They are what makes the Net a network. They define the paths that give users access to content. And they also help to determine which results search engines show over others. Hyperlinks are set neither evenly nor randomly. What does all this mean for political discourse? And which actors are given disproportionately high visibility? A study examines this question.

EPFL researchers have successfully measured some of the quantum properties of electrons in two-dimensional semiconductors. This work in the field of spintronics could one day lead to chips that are not only smaller but that also generate less heat. A group of spintronics researchers at EPFL is using new materials to reveal more of the many capabilities of electrons.

During cold-start, a car engine emits far more particulate matter and other pollutants than during warm conditions. This is because a cold catalytic converter is much less efficient at low exhaust gas temperatures. So what's the answer? Preheat the cat with microwaves. Empa scientists have developed the first microwave converter heating for passenger car applications.

Molecular electronics is a growing research area where scientists study electrical properties of the molecules with a chemically programmed function. Molecules can function as diodes, switches and transistors, all with a typical length of few nanometers. An international group of scientists from University of Bern, Leiden University, Delft University of Technology, and Chuo University has developed the first switchable molecular diode.

EPFL researchers have shown how human operators can maintain control over a system comprising several agents that are guided by artificial intelligence. In artificial intelligence (AI), machines carry out specific actions, observe the outcome, adapt their behavior accordingly, observe the new outcome, adapt their behavior once again, and so on, learning from this iterative process.

ETH researchers have developed a biocompatible ink for 3D printing using living bacteria. This makes it possible to produce biological materials capable of breaking down toxic substances or producing high-purity cellulose for biomedical applications. There will soon be nothing that cannot be produced with 3D printing.

Researchers from EPFL have developed a novel series of systems genetics tools to identify new links between genes and phenotypes. The work, a hallmark of EPFL's endeavors into the advancement of open science, brings biology to the cloud and sets the stage for the development of precision medicine. The study is published in Cell Systems.

A new study by the Institute of Plant Sciences of the University of Bern and the Max Planck Institute for Chemical Ecology shows how the Western corn rootworm puts the maize plants' defense strategies out of action. The results explain why biological control of the crop pest has not been efficient. The Western corn rootworm continues to be on the rise in Europe.

New findings will help to identify the genetic causes of brain disorders: researchers at the Universities of Basel, Bonn and Cologne have presented a systematic catalog of specific variable locations in the genome that influence gene activity in the human hippocampus, as they report Communications. Individual differences in gene regulation contribute to the development of numerous multifactorial disorders.

Bringing social media to unconnected areas
The number of connected devices may be on the rise, but large swaths of the global population still live in areas without telecom infrastructure or a reliable internet connection.

In order to gain insight into how lakes breathe, EPFL scientists have studied oxygen depletion in the depths of Lake Geneva - the first time such research has been carried out. By collecting key data, they were able to enhance their understanding of the lake's ecosystem and how it is likely to evolve over time.

Alzheimer's Tau protein forms toxic complexes with cell membranes
Alzheimer's disease is caused by tangles in the brain made up of malfunctioning aggregated Tau proteins. Scientists at EPFL have discovered a new toxic form of Tau that forms as a result of its interaction with cell membranes. The research is published and provides novel insights into possible mechanisms by which this protein moves in the brain and kills neurons.
