Orphan articles: the 'dark matter' of Wikipedia
Orphan articles: the ’dark matter’ of Wikipedia
Wikipedia is the largest platform for open and freely accessible knowledge online yet, in a new study, researchers have found that around 15% of the content is effectively invisible to readers browsing within Wikipedia. They have developed a new tool to help overcome this. With 60 million articles in more than 300 language versions, Wikipedia's available content grows continuously at a rate of around 200 thousand new articles each month.

Field reality reshapes robotic design
Field reality reshapes robotic design
In 2016, the BBC commissioned two reptilian robots from the BioRob laboratory for a documentary on the African wilderness. The scientists never imagined how testing the devices in the wild would change their approach to robotic design. Auke Ijspeert and his team at the Laboratory of Biorobotics ( BioRob ) in EPFL's Faculty of Engineering had already tested their bio-informed robots in the wild.

Trotting robots reveal emergence of animal gait transitions
Trotting robots reveal emergence of animal gait transitions
A four-legged robot trained with machine learning by researchers has learned to avoid falls by spontaneously switching between walking, trotting, and pronking - a milestone for roboticists as well as biologists interested in animal locomotion. With the help of a form of machine learning called deep reinforcement learning (DRL), the EPFL robot notably learned to transition from trotting to pronking - a leaping, arch-backed gait used by animals like springbok and gazelles - to navigate a challenging terrain with gaps ranging from 14-30cm.

Scientists capture X-rays from upward positive lightning
Scientists capture X-rays from upward positive lightning
Researchers have for the first time recorded X-rays being produced at the beginning of upward positive lightning flashes; an observation that gives important insight into the origins of this rare - and particularly dangerous - form of lightning. Globally, lightning is responsible for over 4,000 fatalities and billions of dollars in damage every year; Switzerland itself weathers up to 150,000 strikes annually.

Energy scientists unravel the mystery of gold's glow
Energy scientists unravel the mystery of gold's glow
Researchers have developed the first comprehensive model of the quantum-mechanical effects behind photoluminescence in thin gold films; a discovery that could drive the development of solar fuels and batteries. Luminescence, or the emission of photons by a substance exposed to light, has been known to occur in semiconductor materials like silicon for hundreds of years.

An ink for 3D-printing flexible devices without mechanical joints
An ink for 3D-printing flexible devices without mechanical joints
Researchers are targeting the next generation of soft actuators and robots with an elastomer-based ink for 3D printing objects with locally changing mechanical properties, eliminating the need for cumbersome mechanical joints. For engineers working on soft robotics or wearable devices, keeping things light is a constant challenge: heavier materials require more energy to move around, and - in the case of wearables or prostheses - cause discomfort.

A new tool for tracing the family trees of cells
A new tool for tracing the family trees of cells
Researchers have developed GEMLI, a pioneering tool that could democratize and vastly improve how we study the journey of cells from their embryonic state through to specialized roles in the body, as well as their changes in cancer and other diseases. In the intricate dance of life, where cells multiply and diversify to form the different parts of organisms, understanding each cell's origin can be crucial.

How the brain senses body position and movement
How the brain senses body position and movement
Researchers at EPFL use neural networks to study proprioception, the sense the brain uses to "know" the body's movement and position. How does your brain know the position and movement of your different body parts? The sense is known as proprioception, and it is something like a "sixth sense", allowing us to move freely without constantly watching our limbs.

3D images reveal link between crack complexity and material toughness
By capturing a rare glimpse into three-dimensional crack formation in brittle solids, researchers have found that complex cracks require more energy to advance than simple ones; a discovery that could improve materials testing and development. The last time you dropped a favorite mug or sat on your glasses, you may have been too preoccupied to take much notice of the intricate pattern of cracks that appeared in the broken object.
