Researchers have managed to produce slow electrons in a solution. In the future, such electrons could help make certain chemical reactions more efficient.

In the case of blood poisoning, the bacteria in the blood must be identified as fast as possible so that a life-saving therapy can be started. Empa researchers have now developed "sepsis sensors" with magnetic nanoparticles that detect bacterial pathogens within a short period of time and identify suitable candidates for antibiotic therapies.

ETH Zurich researchers have found that droughts and land water variability have had an increasing effect on the carbon cycle in the tropics over the last sixty years. Most climate models fail to capture this observation. This could mean that terrestrial ecosystems could absorb less CO₂ than expected in their role as carbon sinks in the future.

Proteins are biological molecules that perform almost all biochemical tasks in all forms of life. In doing so, the tiny structures perform ultra-fast movements. In order to investigate these dynamic processes more precisely than before, researchers have developed a new algorithm that can be used to evaluate measurements at X-ray free-electron lasers such as the SwissFEL more efficiently. They have now presented it in the journal Structural Dynamics.

People who meditate every day are less likely to avoid negative information. This is a finding in a new study by a research team including researchers from ETH Zurich.

In theory, quantum computers vastly outperform classical computers in terms of computing speed. For them to do so in practice, it is necessary to design more and novel high-speed algorithms, says ETH supercomputing specialist Torsten Hoefler.  

Neuroscientists and neurosurgeons from EPFL/CHUV/UNIL and CEA/CHUGA/UGA report in the journal Nature that they have re-established the communication between the brain and spinal cord with a wireless digital bridge, allowing a paralyzed person to walk again naturally

Security of energy supply in a fossil-free Switzerland is feasible and affordable according to a new white paper from an expert group at the Energy Science Center. It will require increased production of renewables and efficient energy trading with neighbouring countries.

In urban water management, the system used for treating wastewater has always been straightforward: wastewater is conveyed through the sewage system to centralised treatment plants, where it is treated. An interdisciplinary research project at Eawag led by Professors Bernhard Truffer and Max Maurer is now challenging this principle, advocating instead a hybrid system with decentralised treatment plants – for use worldwide, but also with potential for Switzerland.

They maintain and repair buildings, observe natural phenomena and transport goods: Drones and robots could play a major role in our lives in the future. With the DroneHub, a kind of aviary is to be created in the NEST research and innovation building on the Empa campus in Dübendorf, where Empa researchers will explore and further develop the interaction of drones, infrastructure and natural habitats together with industrial and academic partners.

Empa researchers have developed novel materials made of carbon that exploit quantum effects to exhibit previously unattainable electronic and magnetic properties. The Werner Siemens Foundation is providing the CarboQuant project with a grant of CHF 15 million. Graphene, nanotechnology and quantum science are now widely used at Empa.

An unexpected discovery about temperature feedback has led to new bionic technology that allows amputees to sense the temperature of objects ­– both hot and cold – directly in the phantom hand. The technology opens up new avenues for non-invasive prosthetics.

If European countries collaborate, they can avoid severe energy scarcity due to a gas shortage. This is the finding of a new study by ETH Zurich researchers.

Yesterday, Swiss President Alain Berset toured the Carbfix plant in Iceland and visited the facilities where the pilot project "DemoUpCARMA" is implemented. The project aims at injecting and storing CO₂ in the Icelandic underground. Marco Mazzotti, project coordinator and ETH Zurich professor, explains why Swiss CO₂ is being shipped all the way to Iceland.

Container-based sanitation has the potential to generate carbon credits through avoided greenhouse gas emissions. Eawag, the Swiss Federal Institute of Aquatic Science and Technology, worked on developing a draft methodology to quantify these emission savings.
