EPFL researchers have developed a high-precision technology that enables them to carve nanometric patterns into two-dimensional materials. With their pioneering nanotechnology, EPFL researchers have achieved the impossible. They can now use heat to break the links between atoms with a miniature scalpel.
Researchers at EPFL's Advanced Quantum Architecture Laboratory and the University of Wisconsin-Madison have developed a technique for building crystal-clear images of moving subjects. The team will present its paper at the prestigious SIGGRAPH 2020 conference in August. In 2019, Edoardo Charbon, a professor at EPFL's School of Engineering (STI), was attending a workshop in Canada.
When we make decisions, we don't always have all options available to choose from at the same time. Instead they often come one after another, so we have to decide on something without knowing if a better option might have come along later. A study at the University of Zurich has shown that our standards drop more and more in the course of decision-making.
In order to reduce the number of animal experiments in research, alternative methods are being sought. This is a particular challenge if the safety of substances that have hardly been studied is to be ensured, for instance, the completely new class of nanomaterials. To accomplish just that, Empa researchers are now combining test tube experiments with mathematical modelling.
The Arctic Ocean will take up more CO2 over the 21st century than predicted by most climate models. This additional CO2 causes a distinctly stronger ocean acidification. These results were published in a study by climate scientists from the University of Bern and École normale supérieure in Paris. Ocean acidification threatens the life of calcifying organisms - such as mussels and "sea butterflies" - and can have serious consequences for the entire food chain.
When analyzing data from the XENON1T detector for dark matter, a signal excess was observed. The UZH researchers do not yet know for sure where this unexpected signal comes from. They say the origins could be relatively banal, but they could also indicate the existence of new particles or hitherto unknown properties of neutrinos.
By deciphering the neural dialogue between the brain's reward and memory networks, neuroscientists from the University of Geneva demonstrate that optimal memory performance requires an intermediate regime of reward delivery. A new finding highly relevant for a variety of learning situations. How does our memory work and how can we optimize its mechanisms on a daily basis? This question is at the heart of many neuroscience research projects.
The live images from the Aquascope reveal an amazing underwater world. Lake Greifen is home to a smorgasbord of wonderful creatures - star-shaped, cylindrical, horned or extravagantly coiffed. But as well as stimulating the imagination, the phytoand zooplankton floating in water serves as an indicator of the ecological status of surface waters.
Scientists at EPFL have developed robust and easy-to-implement multicolor super-resolution imaging. The approach is based on the simultaneous acquisition of two spectral channels followed by spectral cross-cumulant analysis and unmixing. They exploit fluorophore blinking and spectral crosstalk for the generation of additional color channels with super-resolved images.
A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor is that it moves exactly at the boundary between classical motion and quantum tunneling - and has revealed puzzling phenomena to researchers in the quantum realm.
Computers normally store and process data in separate modules. But now researchers at ETH Zurich and the Paul Scherrer Institute have developed a method that allows logical operations to be performed directly within a memory element. Anyone who has ever accidentally pulled out the plug of a desktop computer will recall the painful moment when they realised that any unsaved information was lost forever.
Physicists at EPFL have successfully melted a very thin crystal of magnetic quasi-particles controllably, as turning ice into water. Novel phases of matter have been discovered and a new model system for fundamental physics studies has been established. The introduction of topology, a branch of mathematics focusing on the properties of "knots", into physics has inspired revolutionary concepts such as topological phases of matter and topological phase transitions, which results in the Nobel Prize in Physics in 2016.
Several technical advances have been achieved recently in the pursuit of powerful quantum computers. Now, Computer scientists from ETH Zurich have made an important breakthrough in the field of programming languages: their quantum language is the first of its kind that is as elegant, simple and safe as classical computer languages.
While conducting experiments on a layered metal, EPFL researchers witnessed something very surprising. The unexpected electron behavior they discovered could open up possibilities in the field of quantum computing. In the world of materials science, sometimes main discoveries can be found in unexpected places.
Solving a Parkinson's disease puzzle through protein design
EPFL researchers, in collaboration with UTSW and UCSD scientists, have developed a computational protein design approach, and used it to obtain the first ever high-resolution structure of an activated dopamine receptor in its natural cell membrane environment. The breakthrough will open up a new dimension in drug discovery for Parkinson's disease and perhaps other disorders.

Our sleep during lockdown: longer and more regular, but worse
A survey conducted by the University of Basel and the Psychiatric Hospital of the University of Basel has investigated how sleep has changed during the Covid-19 lockdown. The 435 individuals surveyed - most of whom were women - reported sleeping longer but with a deterioration in sleep quality. The results of the study were published in the scientific journal Current Biology.

Rain enables crops to grow, but it also causes the run-off of pesticides to rivers and streams. Concentrations of these substances in surface waters can be monitored by means of regular sampling. However, with the traditional approach - grab sampling and determination of mean values - it is rarely, if ever, possible to measure the peak concentrations associated with heavy rainfall.
Researchers at ETH have shown that tiny objects can be made from silicon that are much more deformable and stronger than previously thought. In this way, sensors in smartphones could be made smaller and more robust. Since the invention of the MOSFET transistor sixty year ago, the chemical element silicon on which it is based has become an integral part of modern life.
Scientists of Empa and EPFL have developed a fully transparent surgical mask that will soon be produced on an industrial scale.
Living close to human settlements disturbs the social networks of giraffes. They have weaker bonds with other giraffes and fewer interactions with other members of the species, an international study led by the University of Zurich on the social structure of over 500 female giraffes in Tanzania has shown.
