Improving contact-tracing apps in the COVID-19 era
An international collaboration with EPFL has developed a method to improve the performance of COVID-19 contact-tracing apps by taking into account a user's recent contacts, risk levels and shared information about tests and symptoms. Contact-tracing apps like SwissCovid have enormous potential to mitigate the spread of the COVID-19 pandemic.

Light-matter interactions propel quantum technologies forward
Light-matter interactions propel quantum technologies forward
Physicists at EPFL have found a way to get photons to interact with pairs of atoms for the first time. The breakthrough is important for the field of cavity quantum electrodynamics (QED), a cutting-edge field leading the way to quantum technologies. Image: A collection of atom pairs inside an optical cavity formed by a pair of mirrors facing each other.

Viruses leave traces for long after infection
Viruses leave traces for long after infection
Viruses do not always kill the cells they infect. Researchers at the University of Basel have discovered in experiments with mice that cells have the power to self-heal and eliminate viruses. However, these cells undergo long-term changes. The findings may provide a hint as to why cured hepatitis C patients are more susceptible to liver cancer for years after.

Understanding how elephants use their trunk
Understanding how elephants use their trunk
A multidisciplinary team of scientists from the UNIGE identified how elephants evolved strategies that reduce the biomechanical complexity of their trunk. The elephant proboscis (trunk) exhibits an extraordinary kinematic versatility as it can manipulate a single blade of grass but also carry loads up to 270 kilograms.

Faulty regulation of an architect gene can lead to rare bone disease
Faulty regulation of an architect gene can lead to rare bone disease
Researchers found that, if expressed too early during embryonic development, one of the genes that orchestrate the formation of limbs can lead to a rare disorder of bone growth. Mesomelic dysplasias are a group of rare genetic conditions characterized by extreme shortening of the long bones in the arms and legs.

Changes in colour indicate deformations
Changes in colour indicate deformations
Researchers have developed a new type of laminate that changes colour as soon as the material is deformed. This way, the materials researchers can kill two birds with one stone: a lightweight composite material that inspects itself. Lightweight construction has found its way into many areas, especially automotive manufacturing, shipbuilding and aircraft construction.

LiftPose3D: Turning 2D images into 3D models
LiftPose3D: Turning 2D images into 3D models
Scientists have developed a deep learning-based method called LiftPose3D, which can reconstruct 3D animal poses using only 2D poses from one camera. This method will have impact in neuroscience and bioinspired robotics. "When people perform experiments in neuroscience they have to make precise measurements of behavior," says Professor Pavan Ramdya at EPFL's School of Life Sciences, who led the study.

Researchers from IRSOL and IAC solve twenty-year-old paradox in solar physics
Researchers from IRSOL and IAC solve twenty-year-old paradox in solar physics
In 1998, the journal Nature published a seminal letter concluding that a mysterious signal, which had been recently discovered analysing the polarization of sunlight, implies that the solar chromosphere (a very important layer of the solar atmosphere) is practically unmagnetised, in sharp contradiction with common wisdom.

Creation of a detailed 'catalogue' of degradation products in cells
Creation of a detailed ’catalogue’ of degradation products in cells
Cells have their own quality control to prevent the production and accumulation of harmful proteins. This quality control is essential for correct embryonic development in all mammals and plays an important role in tumors and genetic diseases such as cystic fibrosis. A group of researchers from the University of Bern and the University of Basel have now made visible and cataloged for the first time, "blueprints" that give rise to defective proteins and are normally recognized and rapidly degraded in cells.

What If Our History Was Written In Our Grammar?
What If Our History Was Written In Our Grammar?
Humans have been always on the move, creating a complex history of languages and cultural traditions dispersed over the globe. An international team under UZH's lead has now traced families of related languages over more than 10,000 years by combining data from genetics, linguistics and musicology using novel digital methods.

Band-aid for internal wounds
Band-aid for internal wounds
Closing wounds in the digestive tract is a challenge. researchers have now developed a polymer patch for the intestine that can be used to stably bond and seal internal injuries. A burst appendix or a life-threatening intestinal volvulus are emergencies that need to be treated by surgeons immediately.

Cholesterol disrupts lipid metabolism in the cell
Cholesterol disrupts lipid metabolism in the cell
The cell's cholesterol level is decisive for fat regulation and therefore for the lipid metabolism of the entire organism. This has now been demonstrated by a research team at the University of Basel. The team discovered that a specific receptor controls the cholesterol level in the cell and thus the organismal fat metabolism.

Scientific reasoning requires the irrationality of intuition
SUMMER SERIE: HOW SCIENCE WORKS Science is based on coherent reasoning, while intuition follows a more disjointed path. But scientific research couldn't succeed if scientists didn't listen to their gut feelings every once in a while. Science by definition relies on logic, reasoning and rigor. But we've all heard about Archimedes' famous Eureka! moment when, while taking a bath, he suddenly understood what came to be known as Archimedes' principle.

Recreating biology in computer language
Recreating biology in computer language
Toxic substances in the environment can harm the nervous system of fish embryos. Now, researchers at Eawag have developed a computer model that helps to better understand how the damage occurs. Every day, a large number of synthetic chemicals enter streams, lakes and sometimes even drinking water via various pathways.

Lung cancer: Hope for increasing immunotherapy efficacy
A "paradox and setback" forced scientists to dig deeper when seeking a means to boost the power of immunotherapy in lung cancer. Understanding the problem - and finding the solution - has led to a promising potential therapy for some patients. Lung cancer is the leading cause of cancer-related death.

New database could accelerate drug repurposing for various diseases
New database could accelerate drug repurposing for various diseases
NICEdrug.ch, a new database developed by a group of researchers from EPFL, may help scientists assess potential drugs more quickly, including how they are metabolized by the body and their potential side effects. Researchers from EPFL have created a new open-access database of information on drug candidates and how they are metabolized by the body, which could help speed up the repurposing of old drugs as new treatments.

Swimming robot gives fresh insight into locomotion and neuroscience
Thanks to their swimming robot modeled after a lamprey, scientists may have discovered why some vertebrates are able to retain their locomotor capabilities after a spinal cord lesion. The finding could also help improve the performance of swimming robots used for search and rescue missions and for environmental monitoring.

Water management: Deciding despite uncertainties
Water management: Deciding despite uncertainties
How can research support decisions in water management practice, even if much is still uncertain? When managing rivers, for example, the forecasts of what consequences various measures will have are often fraught with uncertainties. It is also not always clear which status is to be achieved in the end with river revitalisation projects, because different stakeholders sometimes pursue different goals, such as recreation, nature conservation, flood protection, fishing or energy generation - and therefore assess possible outcomes in contradictory ways.

Genetic enigma solved: Inheritance of coat color patterns in dogs
Genetic enigma solved: Inheritance of coat color patterns in dogs
An international team of researchers including scientists from the Institute of Genetics of the University of Bern has unraveled the enigma of inheritance of coat color patterns in dogs. The researchers discovered that a genetic variant responsible for a very light coat in dogs and wolves originated more than two million years ago in a now extinct relative of the modern wolf.
