Control for wheelchair robots to mitigate risk of collision in crowds
Control for wheelchair robots to mitigate risk of collision in crowds
Robotic wheelchairs may soon be able to move through crowds smoothly and safely. As part of CrowdBot, an project, researchers are exploring the technical, ethical and safety issues related to this kind of technology. The aim of the project is to eventually help the disabled get around more easily. Shoppers at Lausanne's weekly outdoor market may have come across one of EPFL's inventions in the past few weeks - a newfangled device that's part wheelchair, part robot.

'Hot' spin quantum bits in silicon transistors
’Hot’ spin quantum bits in silicon transistors
Quantum bits (qubits) are the smallest units of information in a quantum computer. Currently, one of the biggest challenges in developing this kind of powerful computer is scalability. A research group at the University of Basel, working with the IBM Research Laboratory in Rüschlikon, has made a breakthrough in this area.

Limiting energy in neurons exacerbates epilepsy
Limiting energy in neurons exacerbates epilepsy
A team led by UNIGE and EPFL has made a counterintuitive discovery in mice: epileptic seizures are more violent when the energy-producing pathway in their neurons is blocked. Epilepsy, one of the most common neurological disorders, is characterized by the spontaneous repetition of seizures caused by the hyperactivity of a group of neurons in the brain.

Popular Male Dolphins Produce More Offspring
Popular Male Dolphins Produce More Offspring
The reproductive success of male dolphins is not determined by strength or age, but via social bonds with other males. The better integrated males are in their social network, the more offspring they produce, a new study by an international team of researchers led by the University of Zurich has shown using long-term behavioral and genetic data.

New world record for qubit storage
New world record for qubit storage
A team from the University of Geneva has succeeded in storing a quantum bit for 20 milliseconds. A duration that had never before been achieved by a solid-state quantum memory. Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure ecommunications networks.

Innovative arthritis treatment combines heat with exercise
Innovative arthritis treatment combines heat with exercise
EPFL engineers have discovered that increasing the temperature of cartilage in the knee during physical exertion could prevent the cartilage from degenerating. "There is currently no treatment for knee arthritis; we can offer only palliative care to reduce the symptoms,- says Prof. Dominique Pioletti, head of the Laboratory of Biomechanical Orthopedics within EPFL's School of Engineering.

'Groundwater, the invisible treasure'
’Groundwater, the invisible treasure’
Groundwater serves as drinking water for around half of the world's population and provides water for over 40 percent of the world's agriculture. So, there is no question that groundwater research plays an important role at Eawag. The aquatic research institute deals with groundwater quality, the regeneration of groundwater, geochemical processes in the subsurface and the treatment of groundwater to produce drinking water , both nationally and internationally.

A gene could prevent Parkinson's disease
A gene could prevent Parkinson’s disease
A team from the University of Geneva has identified a gene whose overexpression prevents the development of Parkinson's disease in the fruit fly and the mouse. Biologists have created mutants of the Fer2 homolog in mouse dopamine neurons. (c) Adobe Stock Parkinson's disease is a neurodegenerative disorder characterized by the destruction of a specific population of neurons: the dopaminergic neurons.

Making cities more livable
Making cities more livable
To meet the challenges in cities related to climate change and increasing urbanization, new approaches to transforming urban space are needed. One possibility are so-called Superblocks, large-scale city blocks with little or even no motorized through traffic inside them. An Empa study has analyzed the potential of different cities to be redesigned according to this principle.

The colored skeletons of Çatalhöyük
The colored skeletons of Çatalhöyük
An international team with participation of the University of Bern provides new insights about how the inhabitants of the "oldest city in the world" in Éatalhöyük (Turkey) buried their dead. Their bones were partially painted, excavated several times and reburied. The findings provide insight into the burial rituals of a fascinating society that lived 9000 years ago.

Novel X-ray lens facilitates glimpse into the nanoworld
Novel X-ray lens facilitates glimpse into the nanoworld
PSI scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens will make it much easier to study nanostructures using X-rays, according to a paper just published by the researchers in the scientific.

Scientists create new lead-free piezoelectric materials
Scientists create new lead-free piezoelectric materials
Researchers have discovered that gadolinium-doped cerium oxide, a compound they created in the lab, could be a promising alternative to certain piezoelectric materials: it has the same proprieties yet may be 100 times more effective. It's also lead-free, unlike the best piezoelectric materials, which means that it could be employed in bio-compatible medical applications.

Deep learning: a framework for image analysis in life sciences
Deep learning models are becoming increasingly common in bioimage analysis. Yet a lack of standardization and the use of these algorithms by non-experts are potential sources of bias. Scientists from EPFL and the European Bioinformatics Institute (EMBL-EBI) offer practical tips and guidance in a paper recently published in the journal IEEE.

Gentler tumor treatment
Gentler tumor treatment
Radiation therapy is one of the cornerstones of cancer therapy. However, some types of tumor respond little or hardly at all to radiation. If it were possible to make tumor cells more sensitive, treatment would be more effective and gentler. Empa and researchers have now succeeded in using metal oxide nanoparticles as "radiosensitizers" - and in producing them on an industrial scale.

Connecting stress, weight, and social anxiety in early adolescence
Scientists at EPFL have found a biological connection explaining why there is an increased predisposition to develop obesity and being less sociable in individuals that have experienced stress during early puberty. Between the end of childhood and the beginning of adolescence, there is a critical window of time referred to as -peripuberty-.

Origins of metastasis
Origins of metastasis
Researchers at the University of Geneva show that the experience of impending cell death within a primary  tumour can lead to the development of «pro-metastatic» cells. Metastatic cells form in a primary tumour and then break away from it, migrate to other organs, attach to them and form new tumours.
