Protect cells from excesses of the immune system
Protect cells from excesses of the immune system
Researchers at EPFL reveal how Drosophila's Turandot proteins protect against immune self-harm. The study is the first to identify some proteins that protect against antimicrobial peptides offering insights into cellular resilience mechanisms with potential therapeutic applications. In the constant battle between organisms and pathogens, our immune system plays the role of a vigilant guardian.

Artificial nanofluidic synapses can store computational memory
Artificial nanofluidic synapses can store computational memory
In a step toward nanofluidic-based neuromorphic - or brain-inspired - computing, EPFL engineers have succeeded in executing a logic operation by connecting two chips that use ions, rather than electrons, to process data. Memory, or the ability to store information in a readily accessible way, is an essential operation in computers and human brains.

Locating single neurons that monitor and regulate the heart and lungs
Locating single neurons that monitor and regulate the heart and lungs
EPFL neuroscientists have located single neurons in a deep structure of the brain that regulates the heart and the lungs, a first detection in humans. The results shed light on how the brain-body system self-regulates both vital bio-rhythms. The body self-regulates in a process known as homeostasis, and the brain is responsible for this as it is constantly monitoring all'of the body's vital signals.

Sustainable plastics from agricultural waste
Sustainable plastics from agricultural waste
Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials. In our rapidly industrialized world, the quest for sustainable materials has never been more urgent. Plastics, ubiquitous in daily life, pose significant environmental challenges, primarily due to their fossil fuel origins and problematic disposal.

The baritone of Red Giants refines cosmic distance measurements
The baritone of Red Giants refines cosmic distance measurements
A fresh look at red giant stars offers key insights into cosmic distance measurements and a way to measure the Universe's expansion with the highest accuracy. In a constantly expanding universe, measuring cosmic distances is like trying to find a reliable ruler in a vast, ever-stretching fabric. One tool that astrophysicists use is the Hubble constant, (H0), which measures how fast the Universe is expanding and sets the age and observable size of the Universe.

Does Artificial Intelligence work in English?
Does Artificial Intelligence work in English?
Researchers have shown that large language models primarily trained on English text seem to use English internally, even when they are prompted in another language. As AI increasingly runs our lives, this may have important consequences regarding linguistic and cultural bias. Large language models (LLMs) including Open AI's ChatGPT and Google's Gemini have taken the world by storm, surprising with their ability to understand and respond to users with seemingly natural speech.

Robotic interface masters a soft touch
Researchers have developed a haptic device capable of reproducing the softness of various materials, from a marshmallow to a beating heart, overcoming a deceptively complex challenge that has previously eluded roboticists. The perception of softness can be taken for granted, but it plays a crucial role in many actions and interactions - from judging the ripeness of an avocado to conducting a medical exam, or holding the hand of a loved one.

The surprising effect of presence hallucinations on social perception
The surprising effect of presence hallucinations on social perception
EPFL neuroscientists have devised a way to alter our social perception and monitor specific types of hallucinations, both in healthy individuals and patients with Parkinson's disease. The test, which is also available online, provides the medical community with a tool to monitor hallucination susceptibility.

Facilitate lake delta renaturation projects
Facilitate lake delta renaturation projects
Engineers from EPFL and partner organizations have developed a method for classifying lacustrine deltas based on morphological parameters, in order to determine which of the deltas severely altered by human activity are best suited for restoration to their natural state. The Reuss delta on the edge of Lake Lucerne is once again a nature-lover's paradise, complete with gravel islands and stretches of shallow water where plants, animals and bathers coexist in harmony.

A new theoretical development clarifies water's electronic structure
A new theoretical development clarifies water's electronic structure
Scientists at EPFL have decoded the electronic structure of water, opening up new perspectives for technological and environmental applications. There is no doubt that water is significant. Without it, life would never have begun, let alone continue today - not to mention its role in the environment itself, with oceans covering over 70% of Earth.

DIY structured-illumination microscope
DIY structured-illumination microscope
Scientists at EPFL have published a guide to building an add-on that turns a standard optical microscope into an instrument capable of producing super resolution, 3D images of cells, organoids, and embryos. For hundreds of years, the optical microscope was the only tool available to scientists wanting to study the movement of cells, bacteria and yeast.

Glacier shrinkage is causing a 'green transition'
Glacier shrinkage is causing a ’green transition’
Glacier-fed streams are undergoing a process of profound change, according to scientists in a paper appearing in Nature Geoscience. This conclusion is based on the expeditions to the world's major mountain ranges by members of the Vanishing Glaciers project. Microbial life will flourish in mountain streams because of ongoing glacier shrinkage.

The 'switch' that keeps the immune system from attacking the body
The ’switch’ that keeps the immune system from attacking the body
Scientists at EPFL uncover the mechanism by which cells mark the protein cGAS for degradation, which is critical in preventing the immune system from mistakenly attacking the body's own tissues. A microscopic battle rages in our bodies, as our cells constantly fend off invaders through our immune system, a complex system of cells and proteins designed to protect us from harmful pathogens.
