Le déficit de traitement de l'épilepsie en Amérique latine est d'environ 60 %, mais le déficit de traitement dans les zones rurales de la région peut atteindre 90 %. En Bolivie, les facteurs contribuant à l'écart de traitement sont similaires aux facteurs dans d'autres régions éloignées à faibles ressources.
Avant la chirurgie, les personnes atteintes d'épilepsie subissent une longue évaluation et des tests approfondis. Mais après une opération chirurgicale, certains professionnels et défenseurs affirment que les gens sont injustement laissés seuls pour gérer le traitement et les soins, sans beaucoup d’aide ou de conseils.
The Korea Institute of Science and Technology (KIST) announced that a team led by Dr. Myung-Jae Lee at the Post-Silicon Semiconductor Institute has developed a "single-photon avalanche diode (SPAD)" that can identify objects at the mm level based on a 40nm back-illuminated CMOS image sensor process.
Jusqu'à la moitié des personnes atteintes d'épilepsie résistante aux médicaments (EFR) peuvent bénéficier d'une intervention chirurgicale. Cependant, dans de nombreuses régions à faibles ressources, la mise en place d'un programme chirurgical nécessite de faire face à de multiples défis, notamment la stigmatisation, le manque de ressources, une formation inadéquate et un financement insuffisant.
Le Plan d’action mondial intersectoriel sur l'épilepsie et les autres troubles neurologiques vise à réduire les écarts diagnostiques et de thérapeutiques de l'épilepsie dans le monde d'ici 2031. Mais dans la pratique, comment améliorer la prise en charge ?

RUDN University biologists and colleagues from Egypt and Saudi Arabia were the first to study the effect of nanoparticles of the natural polymer chitosan on the fish's health in aquaculture. It turned out that chitosan nanogel increases the resistance to a dangerous yeast by 22%. It increases the productivity of fisheries.
Pour les musulmans épileptiques, le jeûne intermittent n'est pas seulement une pratique religieuse très appréciée, mais une méthode possible pour améliorer le contrôle des crises. Les résultats d'une étude récente pourraient guider les professionnels de l'épilepsie dans leurs conseils aux musulmans qui souhaitent participer au Ramadan.
La stigmatisation affecte tous les aspects des soins de l’épilepsie, du diagnostic au traitement en passant par la législation et aux allocations budgétaires. Elle affecte la vie des personnes atteintes d’épilepsie lorsqu’elles n’ont pas un accès égal à l’éducation, à l’emploi et aux mêmes droits sociaux.
Le rôle des soins de santé primaires dans l’identification, le diagnostic et le traitement des personnes atteintes d’épilepsie est de plus en plus important. Cependant, les attitudes sociétales et la stigmatisation entourant l’épilepsie peuvent constituer des obstacles majeurs à l’amélioration des soins.
Malgré les recommandations, le traitement de première intention de l'état de mal épileptique est souvent inapproprié. Des études suggèrent que jusqu'à deux tiers des patients reçoivent des doses subcliniques de benzodiazépines, soit avant d'arriver à l'hôpital, soit pendant un traitement hospitalier d'urgence. Existe-t-il des solutions ?
À l’automne 2021, la section des soins infirmiers de l’ILAE a été créée pour créer un « foyer » pour les infirmières du monde entier qui s’occupent de personnes atteintes d’épilepsie.
The substitution of petrochemical materials with those obtained from renewable raw materials is an important step towards increasing sustainability. In just two years of intensive and open collaboration between Empa and the Datwyler Schweiz AG as part of an Innosuisse project, a process was successfully developed that brought together the worlds of cellulose and rubbers.
An international research team led by drone expert Mirko Kovac of Empa and Imperial College London has taken bees as a model to develop a swarm of cooperative, 3D-printing drones. Under human control, these flying robots work as a team to print 3D materials for building or repairing structures while flying, as the scientists report in the cover story of the latest issue of Nature.
En Ontario, au Canada, un groupe de psychologues et de membres d’un organisme communautaire de soutien à l’épilepsie discutait depuis longtemps de la nécessité d’une éducation sur l’épilepsie pour les enseignants.
A new robot is capable of switching from an underwater drone to an aerial vehicle in less than one second. The robot also features a suction disc inspired by the remora fish, which enables it to hitchhike on wet or dry moving objects to significantly reduce its power consumption. It is designed for biological and environmental monitoring in marine ecosystems such as surveying ocean pollution in the open sea as the scientist of Beihang University, Imperial College London and Empa point out in a new study published in Science Robotics.
A bandage that releases medication as soon as an infection starts in a wound could treat injuries more efficiently. Empa researchers are currently working on polymer fibers that soften as soon as the environment heats up due to an infection, thereby releasing antimicrobial drugs.
Radiation therapy is one of the cornerstones of cancer therapy. However, some types of tumor respond little or hardly at all to radiation. If it were possible to make tumor cells more sensitive, treatment would be more effective and gentler. Empa and ETH Zurich researchers have now succeeded in using metal oxide nanoparticles as "radiosensitizers" – and in producing them on an industrial scale.
Twelve years of intense work are now bearing fruit – researchers at Empa have developed unique carbon materials with quite astonishing, hitherto unattained electronic and magnetic properties, which one day could be used to build quantum computers with novel architectures. A million-dollar grant from the Werner Siemens Foundation for the next ten years now gives this visionary project an unusually long research horizon, greatly increasing the prospects for success.
In a large-scale fundraising campaign, popular YouTubers like Mister Beast and Mark Rober are currently trying to rid the oceans of almost 14,000 tonnes of plastic waste. That's about 0.15 per cent of the amount that ends up in the oceans every year. But it's not just our waters that are full of plastic. A new study shows that the spread of nanoplastic through the air is a more widespread problem than previously thought.
The navigation software group HERE is taking over a software tool developed by Migros and Empa and making it available worldwide. The tool can be used to calculate the CO2 emissions of trucks with different powertrain systems for any route. It can show logistics companies worldwide on which routes hydrogen, electric, biogas or biodiesel trucks can be used and how low their CO2 emissions are compared to diesel-powered trucks.
The Empa spin-off viboo has developed a self-learning algorithm for controlling the indoor climate. This enables predictive cooling or heating of buildings, thus saving around one third of energy. Following successful experiments at NEST, Empa's and Eawag's research and innovation building, the first pilot projects are now being implemented with industrial partners.
Empa and Lidl Switzerland have jointly developed a cellulose protective coating for fruit and vegetables. The novel coating is made from so-called pomace – squeezed fruit and vegetable peels. The innovative project can reduce packaging and prevent food waste.
Short-wave infrared light (SWIR) is useful for many things: It helps sort out damaged fruit and inspecting silicon chips, and it enables night vision devices with sharp images. But SWIR cameras have so far been based on expensive electronics. Researchers at Empa, EPFL, ETH Zurich and the University of Siena have now developed a SWIR screen consisting of just eight thin layers on a glass surface. This could make IR cameras useful everyday objects.

Using an outdoor jacket made from PET bottles and recycled materials, Empa researchers have investigated whether the product actually delivers what the idea promises.
Empa researcher Peter Nirmalraj wants to image proteins with unprecedented precision – and thus gain insights into the molecular pathogenesis of Alzheimer's. This should pave the way for an earlier diagnosis of the dementia disorder via a simple blood test. Together with neurologists from the Kantonsspital St.Gallen, a successful pilot study has now been completed.
A new efficiency record of 21.4% for flexible CIGS solar cell on polymer film has been achieved by scientists at Empa. Solar cells of this type are especially suited for applications on roofs, transport vehicles or mobile devices.
When fluorescent dye molecules nestle perfectly together, something completely new is created: an excited state distributed over many molecules. Such collective excitations can be used in a variety of ways – for organic solar panels, in sensors, for ultrafast data transmission or in microscopy, for example. Empa researchers, together with colleagues from ETH Zurich, EPFL, the Paul Scherrer Institute (PSI) and IBM Research Zurich, have succeeded in making such chemical light amplifiers ten times more efficient than before.
Modern, decentralized energy systems are a highly complex matter. Planning them in an optimal and cost-efficient way is a major challenge for energy planners. Sympheny, an Empa spin-off, offers a software that helps planners to find the most suitable energy concept for a building, neighborhood or even an entire city, and thus to meet their sustainability and energy efficiency goals.
During the winter months, renewable energy is in short supply throughout Europe. An international project is now considering an unconventional solution: Renewable hydrogen and carbon dioxide are pumped into the ground together, where naturally occurring microorganisms convert the two substances into methane, the main component of natural gas.
Bacteria from an Indian landfill could help eliminate contaminated chemicals. The focus is on pesticides such as lindane or brominated flame retardants, which accumulate in nature and in food chains. Researchers at Empa and Eawag used these bacteria to generate enzymes that can break down these dangerous chemicals.
Produced in a sustainable way, synthetic fuels contribute to switching mobility to renewable energy and to achieving the climate goals in road traffic. In the mobility demonstrator "move" Empa researchers are investigating the production of synthetic methane from an energy, technical and economic perspective – a project with global potential.
The number of data-transmitting microdevices, for instance in packaging and transport logistics, will increase sharply in the coming years. All these devices need energy, but the amount of batteries would have a major impact on the environment. Empa researchers have developed a biodegradable mini-capacitor that can solve the problem. It consists of carbon, cellulose, glycerin and table salt. And it works reliably.
An international team led by Empa and ETH Zurich researchers is playing with shape-engineered nanoscale building blocks that are up to 100-times larger than atoms and ions. And although these nano "Lego bricks" interact with each other with forces vastly different and much weaker than those holding atoms and ions together, they form crystals all by themselves, the structures of which resemble the ones of natural minerals. These new mega-crystals or superlattices that are depicted on the cover of the latest issue of "Nature" exhibit unique properties such as superfluorescence – and may well usher in a new era in materials science
High levels of heat and humidity driven by climate change could pose a significant threat to competitors at the Tokyo Olympics in July, a new study backed by leading athletes, the British Association for Sustainability in Sport (BASIS) and scientists from the University of Portsmouth's Extreme Environment Laboratory and the Priestley International Centre for Climate at Leeds University warns.
Scientists at Empa and EPFL have identified a new type of defect as the most common source of disorder in on-surface synthesized graphene nanoribbons, a novel class of carbon-based materials that may prove extremely useful in next-generation electronic devices. The researchers identified the atomic structure of these so-called "bite" defects and investigated their effect on quantum electronic transport. These kinds of defective zigzag-edged nanoribbons may provide suitable platforms for certain applications in spintronics.
Climate-related temperature rises will further increase the cooling demand of buildings. A projection by Empa researchers based on data from the NEST building and future climate scenarios for Switzerland shows that this increase in energy demand for cooling is likely to be substantial and could have a strong impact on our future – electrified – energy system.
Even a sustainable circular economy doesn't run without energy. Solar panels and wind farms, tidal and geothermal power plants: They all divert energy from energy fluxes that had remained untapped since time immemorial. The question is therefore: What part of these energy fluxes can mankind use for its own purposes without damaging the Earth's energy system? Empa researchers have developed an approach to estimate this.
Removing pathogens from drinking water is especially difficult when the germs are too tiny to be caught by conventional filters. Researchers at Empa and Eawag are developing new materials and processes to free water from pathogenic microorganisms such as viruses.

Researchers at the Paul Scherrer Institute PSI and the partner institute Empa have started a joint initiative called SynFuels. The goal is to develop a process for producing kerosene from renewable resources. In this way liquid fuel mixtures of the highest quality, which would allow the most residue-free combustion possible and thus be suitable for aircraft propulsion, should be obtainable using carbon dioxide and hydrogen from renewable resources.
After a mysterious and sharp increase between 2012 and 2017 that could be traced to eastern China global emissions of a potent (and banned) substance notorious for depleting the Earth’s ozone layer – the protective barrier that absorbs the Sun’s harmful UV rays – have fallen rapidly in recent years and are now as low as never before since measurements began in this region in 2008, according to new atmospheric analyses published in "Nature" today.
Where do the greatest risks of infection lurk? How can you protect yourself and others even better? Scientists all over the world are working to expand knowledge about Covid-19 – including at Empa.
