Bacteria not only develop resistance to antibiotics, they also can pick it up from their rivals. In a recent publication in "Cell Reports", Researchers from the Biozentrum of the University of Basel have demonstrated that some bacteria inject a toxic cocktail into their competitors causing cell lysis and death.

Researchers from the University of Bern, Inselspital, Bern University Hospital and the Swiss Center for Electronics and Microtechnology develop a high-precision, sensor-based surgical robot for spinal operations together with industry partners. Their project is being funded with two million Swiss francs, sponsored by the "BRIDGE" programme of the Swiss National Science Foundation and the Commission for Technology and Innovation.

The Swiss Tropical and Public Health Institute, together with European and African collaborators, carried out a mass dog vaccination in Chad and determined its effect on human rabies exposure. The study employed a bio-mathematical method for estimating the transmission dynamics of rabies. The researchers conclude that with political will and the necessary funding, elimination of rabies is possible in Africa.

OCUVIS, a visualization software developed by a soon-to-be-launched EPFL spin-off, lets architects simulate 3D building models to assess the performance of natural light indoors. After specifying the ambient conditions, architects can view the visual and non-visual characteristics of the resulting natural light in their designs.

EPFL researchers have created nanoparticles that attract viruses and, using the pressure resulting from the binding process, destroy them. This revolutionary approach could lead to the development of broad-spectrum antiviral drugs. HIV, dengue, papillomavirus, herpes and Ebola - these are just some of the many viruses that kill millions of people every year, mostly children in developing countries.

EPFL scientists have discovered that neutrophils, a type of immune cell, can actually help lung tumors grow. The work is published in Cell Reports, and has enormous implications for cancer immunotherapy. Neutrophils inside lung adenocarcinoma tumors. On the left, neutrophils inside a mouse tumor are stained brown; on the right, neutrophils inside a human tumor are stained red (credit: E. Meylan/EPFL).

Autophagy refers to a fundamental recycling process of cells that occurs in yeast, fungi, plants, as well as animals and humans. This process allows cells to degrade their own components and thus activate energy resources to be able to adapt to nutritional needs. In addition, autophagy plays a central role in steering an organism's immune response.

Investigational therapy crizanlizumab (SEG101, formerly SelG1) approximately doubled the time to first on-treatment sickle cell pain crisis, according to new subgroup analysis of Phase II SUSTAIN data Results were consistent across patient subgroups despite differences in disease severity, genotype or background therapy New findings for crizanlizumab, a potential disease-modifying, preventive treatment option for patients with sickle cell diseas

Lipid, also known as fat, is an optimal energy source and an important cell component. Much is required for the rapid and uncontrolled growth of cancer cells. Researchers from the Biozentrum of the University of Basel and from the University of Geneva have now discovered that the protein mTOR stimulates the production of lipids in liver tumors to satisfy the increased nutrient turnover and energy needs of cancer cells among other functions.

Using a bioinformatics and experimental approach, scientists at EPFL have found that rendering mitochondria resistant to damage can halt diseases caused by amyloid toxicity, such as Alzheimer's disease. Alzheimer's disease is the most common form of dementia and neurodegeneration worldwide. A major hallmark of the disease is the accumulation of toxic plaques in the brain, formed by the abnormal aggregation of a protein called beta-amyloid inside neurons.

EPFL researchers have shown how human operators can maintain control over a system comprising several agents that are guided by artificial intelligence. In artificial intelligence (AI), machines carry out specific actions, observe the outcome, adapt their behavior accordingly, observe the new outcome, adapt their behavior once again, and so on, learning from this iterative process.

ETH researchers have developed a biocompatible ink for 3D printing using living bacteria. This makes it possible to produce biological materials capable of breaking down toxic substances or producing high-purity cellulose for biomedical applications. There will soon be nothing that cannot be produced with 3D printing.

Researchers from EPFL have developed a novel series of systems genetics tools to identify new links between genes and phenotypes. The work, a hallmark of EPFL's endeavors into the advancement of open science, brings biology to the cloud and sets the stage for the development of precision medicine. The study is published in Cell Systems.

New findings will help to identify the genetic causes of brain disorders: researchers at the Universities of Basel, Bonn and Cologne have presented a systematic catalog of specific variable locations in the genome that influence gene activity in the human hippocampus, as they report Communications. Individual differences in gene regulation contribute to the development of numerous multifactorial disorders.

The number of connected devices may be on the rise, but large swaths of the global population still live in areas without telecom infrastructure or a reliable internet connection.

Alzheimer's disease is caused by tangles in the brain made up of malfunctioning aggregated Tau proteins. Scientists at EPFL have discovered a new toxic form of Tau that forms as a result of its interaction with cell membranes. The research is published and provides novel insights into possible mechanisms by which this protein moves in the brain and kills neurons.

Most people in Switzerland die in hospitals and nursing homes. Their specific needs are often not adequately met.

Mycoplasma bacteria are one of the most common causes of bacterial pneumonia in children. It is still unclear how the disease develops.
