Antibody-peptide inhibitor conjugates: a new path for cancer therapy
Cancer treatments often struggle with balancing efficacy and side effects. A new study by scientists offers a promising solution using antibody-peptide inhibitor conjugates to target specific cell types and block the activity of cancer-promoting enzymes called cathepsins. Tumor cells often hijack normal physiological processes to support their growth, exploiting proteins that are in charge of essential cell functions.

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
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
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
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.

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.
