Researchers at ETH have developed a technique to cool several nanoparticles simultaneously to temperatures of just a few thousandths of a degree above absolute zero. This new method can be used to study quantum effects of several nanoparticles and to build highly sensitive sensors. Over the past forty years, physicists have learned to cool increasingly large objects down to temperatures close to the absolute zero: atoms, molecules and, more recently, also nanoparticles consisting of billions of atoms.
Borrowing from methods used to produce optical fibers, researchers from EPFL and Imperial College have created fiber-based soft robots with advanced motion control that integrate other functionalities, such as electric and optical sensing and targeted delivery of fluids. Over the past decades, catheter-based surgery has transformed medicine, giving doctors a minimally invasive way to do anything from placing stents and targeting tumors to extracting tissue samples and delivering contrast agents for medical imaging.
Liver cancer: How liver cells go astray
Liver cancer is one of the most deadly types of cancer. A team of University of Basel researchers has now uncovered how a healthy liver cell turns into a tumor cell. Comprehensive metabolic changes convert mature liver cells into immature progenitor cells. These cells proliferate rapidly and tumors develop.

Researchers from ETH Zurich and the University of Zurich are taking magnetic resonance imaging a step further. With their new method, they can visualise metabolic processes in the body. Their objective is to improve the future diagnosis and treatment of heart disease. Magnetic resonance imaging (MRI) has become an indispensable part of medicine.
Scientists at EPFL, Ludwig Institute of Cancer Research, and CHUV have identified a key protein that helps tumors evade attacks by the immune system, contributing to poor responses to immunotherapy in the clinic. Immunotherapy is a cutting-edge approach to treating cancer by turning the patient's own immune system against their tumor.
How an Emerging Drug Class Dampens Harmful Immune Reactions
Although the complement system forms part of the innate immune system, it can cause damage to the body in some cases. This is because unwanted complement activation contributes to many autoimmune and chronic inflammatory diseases. Now, researchers have described molecular details of a recently approved class of drugs that can inhibit the complement system.

Researchers are developing a medical chip in collaboration with the ETH Zurich and the Cantonal Hospital of St.Gallen that will allow statements to be made about the effect of substances on babies in the womb. The Zurich-based ProCare Foundation is funding the project, which was recently launched.
Over 10,000 people in both the French and Swiss parts of the Lake Geneva region have been surveyed on their transportation habits, as the first element of a broader EPFL study on consumer lifestyles and behavior. The study is being spearheaded by EPFL's School of Architecture, Civil and Environmental Engineering (ENAC), working in association with the Canton of Vaud, the Canton of Geneva and Greater Geneva.
Researchers at Eawag recommend setting up a monitoring system for antibiotic resistance in the synthesis report of the National Research Programme NRP 72 Antimicrobial resistance, similar to the wastewater monitoring for Sars-CoV-2. Antibiotic resistance endangers human and animal health worldwide. In order to be able to introduce effective measures against antibiotic-resistant pathogens, it is important to have detailed knowledge of the current situation and how resistances are spreading in the environment.
Tuberculosis (TB) remains one of the world's biggest infectious disease killers. It is a complicated disease to diagnose and treat, even more so when it affects organs outside of the lung. A clinical trial in Tanzania tested a diagnostic algorithm including point-of-care ultrasound to increase the proportion of correctly managed patients.
Two students from the School of Life Sciences FHNW have developed a new type of 3D printer in close collaboration with the orthopedic company Orthopodo Malgaroli. With this, Orthopodo can now print custom-fit orthopedic foot orthoses for its customers quickly, easily and in a resource-saving manner.
Although the coronavirus known as SARS-CoV-2 does not infect nerve cells, it can cause damage to the nervous system. Researchers from the University of Basel and University Hospital Basel have studied the mechanisms responsible for this effect, known as -neuro-Covid-, and identified starting points for its prevention.
Scientists at EPFL and the Consiglio Nazionale delle Ricerche (CNR), the University Federico II, and CEINGE-Biotecnologie avanzate in Naples, Italy, have developed a new method to screen individual cells quickly and reliably without fluorescence labeling. Their work, published in the journal Nature Photonics, opens new avenues in early tumor diagnosis and drug development.
Researchers at the University of Basel have uncovered a cell-intrinsic mechanism that controls the appropriate number of T cells in the organism and thus ensures that the immune system functions properly. This mechanism has also been found in slime molds, suggesting that this regulation of cell density is evolutionarily conserved.
A team from the University of Geneva and LMU developed a transport nanoparticle to make an anti-inflammatory drug much more effective and less toxic. How can a drug be delivered exactly where it is needed, while limiting the risk of side effects? The use of nanoparticles to encapsulate a drug to protect it and the body until it reaches its point of action is being increasingly studied.
With the use of a precision experiment developed at the University of Bern, an international research team has succeeded in significantly narrowing the scope for the existence of dark matter. The experiment was carried out at the European Research Neutron Source at the Institute Laue-Langevin in France, and makes an important contribution to the search for these particles, of which little remains known.
Scientists identify neurons that restore walking after paralysis
A new study by scientists at the.NeuroRestore research center has identified the type of neuron that is activated and remodeled by spinal cord stimulation, allowing patients to stand up, walk and rebuild their muscles - thus improving their quality of life. This discovery, made in nine patients, marks a fundamental, clinical breakthrough.

Motivation is affected by oxidative stress in the brain, a study by EPFL and Nestlé shows. The findings also suggest motivation can be improved through nutritional interventions. In life, motivation can be the difference between success and failure, goal-setting and aimlessness, well-being and unhappiness.
Together with EPFL and ETH Zurich colleagues, an Empa team is developing next-generation VR gloves that will make virtual worlds tangible. The glove is to be tailored to each user and capable of being produced largely automatically - using a 3D printing process. Research sometimes needs a sacrifice.
In a study, 70 researchers from 19 countries around the world call for measures to better understand and reduce the impact of climate change on insects. Otherwise, they say, the chance of a sustainable future with healthy ecosystems will be drastically reduced. The researchers also outline ways to help insects in a warming world.
