Researchers outsmarted EasyRide function on Swiss travel app
Researchers outsmarted EasyRide function on Swiss travel app
Experiments by ETH Zurich computer security researchers showed that smartphones can be manipulated to allow the owner to ride Swiss trains for free. The researchers also highlighted ways of curbing such misuse. It makes travelling by train, bus and tram super easy: instead of buying a conventional ticket, people using the EasyRide function in the SBB app can start their journey with a single swipe on their smartphone.

Portable method lets scientists identify plant DNA out in the field
Portable method lets scientists identify plant DNA out in the field
In EPFL's GenoRobotics project, a cross-disciplinary team of students is developing a novel method for identifying plant DNA - one that's faster, cheaper and less energy-intensive than the conventional one. The team hopes their new protocol, designed for use out in the field, will make it easier to categorize plants and ultimately help protect biodiversity.

Discovery of a planet around an ultra-cool star
Artist's concept of the exoplanet SPECULOOS-3 b orbiting its ultra-cool red dwarf star. The planet is as big as Earth, while its star is slightly larger than Jupiter, but much more massive. Credit: NASA/JPL-Caltech An international team of astronomers - including members of the NCCR PlanetS , the University of Geneva and the University of Bern (UNIBE) - has discovered, for only the second time, an Earth-sized exoplanet (SPECULOOS-3 b) around an ultra-cool Red Dwarf star.

Mosaic grassland landscapes are the most beneficial
Mosaic grassland landscapes are the most beneficial
Like forests, grassland provides numerous ecological, economic and social benefits. Researchers in the Swiss canton of Solothurn have investigated ways to maintain and improve these benefits. Grass, clover and herbs are the foundation of Swiss agriculture: two-thirds of Switzerland's agricultural land is grassland, much of which is barely suitable for arable farming.

New gel breaks down alcohol in the body
New gel breaks down alcohol in the body
Researchers at ETH Zurich have developed a protein-based gel that breaks down alcohol in the gastrointestinal tract without harming the body. In the future, people who take the gel could reduce the harmful and intoxicating effects of alcohol. Most alcohol enters the bloodstream via the mucous membrane layer of the stomach and the intestines.

Reaction of trees to heat unravelled
Reaction of trees to heat unravelled
At temperatures above 30°C, water loss through transpiration increases in trees, while CO2 uptake decreases - even when there is enough CO2 in the atmosphere. Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL were able to show this in a study conducted using a new high-tech facility.

Electron vortices in graphene detected
Electron vortices in graphene detected
Researchers at ETH Zurich have, for the first time, made visible how electrons form vortices in a material at room temperature. Their experiment used a quantum sensing microscope with an extremely high resolution. When an ordinary electrical conductor - such as a metal wire - is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery.

Solving physics puzzles with coloured dots
Solving physics puzzles with coloured dots
By analysing images made of coloured dots created by quantum simulators, researchers have studied a special kind of magnetism. In the future this method could also be used to solve other physics puzzles, for instance in superconductivity. Up close it looks like lots of coloured dots, but from a distance one sees a complex picture rich in detail: Using the technique of pointillism, in 1886 George Seurat created the masterpiece ,,A Sunday afternoon on the island of La Grande Jatte".

Limited Adaptability Makes Freshwater Bacteria Vulnerable to Climate Change
Limited Adaptability Makes Freshwater Bacteria Vulnerable to Climate Change
Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from Lake Zurich and other European lakes, researchers at the University of Zurich uncovered specific evolutionary strategies that shape these bacteria's lifestyles.

Hints of a possible atmosphere around a rocky exoplanet
Hints of a possible atmosphere around a rocky exoplanet
Researchers using NASA/ESA/CSA James Webb Space Telescope may have detected an atmosphere surrounding 55 Cancri e, a rocky exoplanet 41 light-years from Earth. This is the best evidence to date for a rocky planet atmosphere outside our solar system. Brice-Olivier Demory, Professor of Astrophysics at the University of Bern and member of the the National Centre of Competence in Research (NCCR) PlanetS, was part of the international research team that just published the results in Nature.

How rising treelines can affect Alpine lakes
How rising treelines can affect Alpine lakes
An EPFL scientist along with colleagues from universities across Europe have completed the first-ever quantitative study of the changes that soil organic matter from forests can cause in high-altitude and high-latitude lakes once it's dissolved in the water Treelines are rising around the world as a result of global warming.

Experiment opens door for millions of qubits on one chip
Researchers from the University of Basel and the NCCR SPIN have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.

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.

154 million deaths averted: Contribution of vaccination over the past 50 years
In 1974, the World Health Organization launched its Expanded Programme on Immunization. Now, 50 years later, a study shows that an estimated 154 million deaths have been averted thanks to immunization. The study, led by Swiss TPH in collaboration with the WHO and numerous research organizations, is published in The Lancet.

Leprosy in the Middle Ages: New Insights on Transmission Pathways through Squirrels
Researchers at the University of Basel and the University of Zurich have been able to prove that British squirrels carried leprosy bacteria as early as the Middle Ages. Further results revealed a link between the pathogens found in the medieval rodents and those in the local human population during that period.

Blood diagnostics modelled on leeches
Researchers at ETH Zurich have developed a safe and inexpensive device for reliable blood measurements. It works using a suction cup and could also be employed to diagnose the tropical disease malaria - even by non-medical personnel. Many people are afraid of needles, and having a doctor take a blood sample from their arm makes them uncomfortable.

A new anticoagulant with no risk of bleeding
A team from the University of Geneva, in collaboration with the University of Sydney, has developed a new type of anticoagulant whose action can be rapidly stopped. Anticoagulant treatments are crucial for managing many conditions, such as heart disease, stroke and venous thrombosis. Current options, however, carry an inherent risk of serious bleeding due to trauma or unforeseen events.

How the plant world shapes the climate cycle
How the plant world shapes the climate cycle
In order to understand the Earth's resilience, researchers at ETH Zurich are modelling climate changes from times long past. And they show: Plants are not simply victims of circumstances, but have helped to shape climate conditions on Earth. Over the course of hundreds of millions of years, Earth has lived through a series of climatic shifts, shaping the planet as we know it today.
