Organoids are miniature lab-grown tissue structures that can mimic real organs. But guiding stem cells to grow an organoid of defined shape and size is difficult. Now, EPFL bioengineers have developed new methods for successfully guiding the stem cells to grow into intestinal tissues with real-life 3D structure and function.

A team of researchers led by ETH Professor Rafael Polanía has shown for the first time that decisions feel right to us if we have compared the options as attentively as possible – and if we are conscious of having done so. This requires a capacity for introspection.

Chemical engineers at EPFL have developed a new approach to artificial photosynthesis, a method for harvesting solar energy that produces hydrogen as a clean fuel from water.

All living organisms that respire have to get rid of electrons. In oxygen-free environments, microorganisms deploy special molecules which act as extracellular electron shuttles to transfer the electrons from cells to minerals. A group of researchers has now discovered what determines the electron transfer efficiency of these “taxi” cars: the energy differences of the transported electrons.

Stroke survivors have improved recovery of hand and arm function with the help a new rehabilitation protocol thanks to finely tuned electrostimulation of target muscles in the arm.

A study under co-leadership of the ETH Zurich has shown that computer algorithms can determine antimicrobial resistance of bacteria faster than previous methods. This could help treat serious infections more efficiently in the future.

Most trees live in symbiosis with fungi. ETH Zurich researchers show just how important this partnership is for tree growth through the first-ever comprehensive data analysis compiled for European forests on a massive scale.

EPFL scientists have studied the unique features of the decorative vaulting known as muqarnas in Spain’s Alhambra palace and fortress complex. Muqarnas are commonly found in Islamic architecture, yet they are poorly understood by the architectural community and the little data that exist on them have been simplified over time. The EPFL study firmly anchors the Alhambra’s wonders in our world heritage.

At EPFL, a team of scientists created and observed a new physical phenomenon on an optical chip using modified lights.

Engineers at EPFL have developed a method for reading several qubits – the smallest unit of quantum data – at the same time. Their discovery paves the way to a new generation of even more powerful quantum computers.

Without stronger climate action, the five biggest emitters will double the number of countries regularly experiencing extreme hot years by 2030.

A PhD student at EPFL studied the use of automated control systems for blinds and electric lighting to regulate the amount of daylight in an office, and found that such systems can cut a building’s energy demand and stimulate occupants’ circadian rhythms, improving their health and well-being.

An electric car that runs on PV power sounds appealing. But is it really possible to enjoy flexibility with a vehicle charged through a home photovoltaic system? An ETH research team has reached some surprising conclusions.

PSI scientists have shed light on an important component of the eye: a protein in the rod cells of the retina which helps us see in dim light. Acting as an ion channel in the cell membrane, the protein is responsible for relaying the optical signal from the eye to the brain. If a genetic disorder disrupts the molecular function in a person, they will go blind. Scientists have deciphered the protein’s three-dimensional structure, preparing the way for innovative medical treatments. The study is published in the scientific journal Nature Structural & Molecular Biology.

How much does a country's vehicle fleet consume on average? How does it change from year to year? With the increasing number of electric vehicles and more and more "crossover" models that can hardly be assigned to one vehicle segment, analysis is becoming increasingly difficult. Empa researchers analyze databases using deep learning methods - and can make precise statements: In which region of the country do the fattest cars drive? What can car buyers do to reduce CO₂ consumption?
