The ease of creating fake virtual identities plays an important role in shaping the way information - and misinformation - circulates online. Could 'pseudonym' parties, that would verify proof of personhood not proof of identity, resolve this tension' Social media platforms have completely changed the way information flows online.

Power converters play an essential role in electric vehicles and solar panels, for example, but tend to lose a lot of power in the form of heat in the electricity conversion process. Thanks to a new type of transistor developed at EPFL, these converters can perform at substantially improved efficiencies, especially in high-power applications.

EPFL Pavilions re-opens its exhibition Nature of Robotics which offers perspective on robotics in a human and organic environment. At the entrance of Nature of Robotics a couple of robotic snails slither around the floor, leaving behind slimy trails. Two visitors, young boys, enter the exhibit and squat next to the slimy creatures, trying to follow both of them at once.

Motivated by the goal of reducing the polarization of opinions online, new EPFL/UNIL research indicates that this may be far more difficult than expected, even when using liked or respected celebrities as spokespeople. Celebrities, thanks to their level of fame, are often considered to be influential and many have used their status to campaign for issues they believe to be important - consider Beyoncé's feminist activism or Leonardo DiCaprio's outspokenness on Climate Change.

EPFL will soon be home to a European hub for high-performance computing focused on fusion power - a potential source of clean, risk-free energy. As part of this effort, EPFL's Swiss Plasma Center will lead a campus-wide, cross-disciplinary research team. EUROfusion - or the European Consortium for the Development of Fusion Energy, which consists of organizations from 28 European countries - has just selected EPFL as the site for its Advanced Computing Hub.

Scientists have developed a new dye for solar cells that enables high power-conversion efficiency while being simple and cheap to make. The dye also works exceptionally well under low-light conditions, which is key for selfand low-powered devices. In 1991, scientists Brian O'Regan and Michael Grätzel at EPFL published a seminal paper describing a new type of solar cell: the dye-sensitized solar cell (DSSC), also known as "Grätzel cell".

Lung tumors are home to immune cells that affect their growth and resistance to treatment. Looking at neutrophils, scientists led by EPFL have discovered that the key might lie in the cells' ability to metabolize glucose, opening an entirely new target for improving radiotherapy. Cancers are not only made of tumor cells.

Combining structural biology, molecular simulations, mutagenesis, and in vivo assays, EPFL scientists have made the first extensive study of the mode of action of the enzyme acyl thioesterase, which regulates deacylation, one of the most critical functions of the cell. S'acylation is the process of chemically linking a lipid to protein via a thioester bond.

Scientists at EPFL and the University of Geneva have combined two powerful, cutting-edge techniques to uncover the physics behind an exotic phase transition that turns a metal into an insulator. The materials they looked at are rare-earth nickelates, which are of great interest for innovating new approaches in electronics.

A team of EPFL engineers has developed technology that could partially restore vision in blind people. Being able to make blind people see again sounds like the stuff of miracles or even science fiction. And it has always been one of the biggest challenges for scientists. Diego Ghezzi, who holds the Medtronic Chair in Neuroengineering (LNE) at EPFL's School of Engineering, has made this issue a research focus.

One thousand newly-minted microrobots created in EPFL labs will soon be deployed at two large-scale telescopes in Chile and the United States. These high-precision instruments, capable of positioning optical fibers to within a micron, will vastly increase the quantity of astrophysics data that can be gathered - and expand our understanding of the Universe.

Chemical engineers at EPFL have developed a graphene filter for carbon capture that surpasses the efficiency of commercial capture technologies, and can reduce the cost carbon capture down to $30 per ton of carbon dioxide. One of the main culprits of global warming is the vast amount of carbon dioxide pumped out into the atmosphere mostly from burning fossil fuels and the production of steel and cement.

Hyaluronic acid, also known as hyaluronan, is a polysaccharide that helps establish the viscosity of bodily fluids. According to a new study by EPFL scientists, it also influences the behavior of far more water molecules than previously thought. Their findings - just published in Science Advances - open new avenues of research on the role water plays in the human body.

New EPFL research on whether handwriting skills transfer when a child writes in two different alphabetic scripts may pave the way for cross-lingual digital tools for the detection of handwriting difficulties. Despite the increasing digitization of education and the use of use of tablets and laptops in schools, handwriting has maintained its central position in learning as the basis of many core educational activities such as taking notes, composing stories and self-expression.

Scientists led by EPFL have developed a breakthrough in vivo model for invasive lobular carcinoma, a serious yet understudied type of breast cancer. The work will open up previously inaccessible study of the tumor's biology and help discover new therapies. Invasive lobular carcinoma (ILC) is a type of breast cancer that begins in the milk-producing glands (lobules) of the breast.

By using 3D aerosol jet-printing to put perovskites on graphene, scientists at EPFL have made X-ray detectors with record sensitivity that can greatly improve the efficiency and reduce the cost and health hazard of medical imaging devices. Since Wilhelm Röntgen discovered them in 1895, X-rays have become a staple of medical imaging.

Using the IBM Q computer, physicists at EPFL have verified for the first time the tight relationship between quantum entanglement and wave-particle duality, showing that the former controls the latter in a quantum system. "It is possible to do experiments in fundamental physics on the remotely accessible IBM Q quantum computer ," says Marc-André Dupertuis, a physicist at EPFL's School of Basic Sciences.

The core of a fusion reactor is incredibly hot. Hydrogen that inevitably escapes from it must be cooled on its way to the wall, as otherwise, the reactor wall would be damaged. Researchers from the Dutch institute DIFFER and EPFL's Swiss Plasma Center have developed a strict measurement and control method for the cooling of very hot particles escaping from fusion plasmas.

Scientists have developed a method for boosting the sensitivity of rapid-detection tests like those used for the new coronavirus. The results of their feasibility study have just been published in Nano Letters. Pregnancy tests and rapid-detection tests for the new coronavirus work in the same way. They contain a surface - usually made of metal - on which chemical nanosensors detect specific compounds in a sample of urine, saliva or blood that indicate the presence of a given protein or part of a virus.
