How to turn a tentacle into a foot
How to turn a tentacle into a foot
By identifying a key regulator of cell identity, a team from the University of Geneva and the FMI has succeeded in modifying the structure and function of tentacle cells in hydra. Humans, animals, plants: all multicellular organisms are made up of specialized cells called differentiated cells. Thus, the cells that make up the epidermis do not have the same identity - nor the same function - as those that line the digestive system, for example.

The forgotten half of the brain to recover memory
The forgotten half of the brain to recover memory
A research team at the University of Lausanne has succeeded in preserving the memory of Alzheimer's mice by boosting the metabolic functions of glial cells rather than neurons, a striking shift in treatment strategies. The results can be found in the journal "Glia". Alzheimer's disease progressively affects the memory until the loss of autonomy of individuals.

Polarity proteins shape efficient 'breathing' pores in grasses
Polarity proteins shape efficient ’breathing’ pores in grasses
A research group at the University of Bern is studying how plants "breathe". They have gained new insights into how grasses develop efficient "breathing pores" on their leaves. If important landmark components in this development process are missing, the gas exchange between plant and atmosphere is impaired.

The clever glue keeping the cell's moving parts connected
The clever glue keeping the cell’s moving parts connected
Researchers from Paul Scherrer Institute PSI and ETH Zurich have discovered how proteins in the cell can form tiny liquid droplets that act as a smart molecular glue. Clinging to the ends of filaments called microtubules, the glue they discovered ensures the nucleus is correctly positioned for cell division.

From molecules to organisms
From molecules to organisms
How did life on Earth first emerge? And how was it able to prosper and evolve? researchers are involved in the quest to find answers to these fundamental questions. Since time immemorial, humanity has pondered the question of how life on Earth first began. Ancient cultures declared the creation of the world and the origin of life to be the work of gods and other divine beings.

Early green, early brown - climate change leads to earlier senescence in alpine plants
Early green, early brown - climate change leads to earlier senescence in alpine plants
Global warming is leading to longer growing seasons worldwide, with many plants growing earlier in spring and continuing longer in autumn thanks to warmer temperatures-so the general opinion. Now, however, plant ecologists at the University of Basel have been able to show that this is not the case for the most common type of alpine grassland in the European Alps, where an earlier start leads to earlier aging and leaves the grassland brown for months.

New Virus Discovered in Swiss Ticks
New Virus Discovered in Swiss Ticks
The Alongshan virus was discovered in China only five years ago. Now researchers at the University of Zurich have found the novel virus for the first time in Swiss ticks. It appears to be at least as widespread as the tickborne encephalitis virus and causes similar symptoms. The UZH team is working on a diagnostic test to assess the epidemiological situation.

Fighting cancer is more efficient at dawn
Fighting cancer is more efficient at dawn
Scientists from the UNIGE and LMU show that the anti-tumour activity of the immune system - and the effectiveness of cancer immunotherapies - depends on the time of day. The ability of tumours to take hold and grow depends, among other things, on the effectiveness of the immune system in fighting them.

Locomotion modeling evolves with brain-inspired neural networks
Locomotion modeling evolves with brain-inspired neural networks
A team of scientists at EPFL have built a new neural network system that can help understand how animals adapt their movement to changes in their own body and to create more powerful artificial intelligence systems. Deep learning has been fueled by artificial neural networks, which stack simple computational elements on top of each other, to create powerful learning systems.

How chemical modifications on DNA keep genes off
How chemical modifications on DNA keep genes off
Several diseases, including certain types of cancer and some neurodevelopmental conditions, have aberrant patterns of DNA methylation, a chemical modification that regulates gene expression in ways that keep genes in the 'off' position. FMI researchers found that DNA methylation keeps genes silent mostly by inhibiting the binding of DNA by transcription factors — proteins that control how genes are expressed.

Genes and Languages
Genes and Languages
Does the history of our languages match the history of our genes? A team of scientists at the University of Zurich and the Max-Planck-Institute have revealed a large number of matches - but also widespread mismatches in around 20 percent of cases, including in Malta, Hungary and Namibia. More than 7,000 languages are spoken in the world.

Covid-19: the Spike protein is no longer the only target
Covid-19: the Spike protein is no longer the only target
A research team reveals a hidden cavity on a key SARS-CoV-2 protein to which drugs could bind. With the continuous emergence of new variants and the risk of new strains of the virus, the development of innovative therapies against SARS-CoV-2 remains a major public health challenge. Currently, the proteins that are on the surface of the virus and/or are involved in its replication are the preferred therapeutic targets, like the Spike protein targeted by vaccines.

Scientists unlock nature's secret to super-selective binding
Scientists unlock nature's secret to super-selective binding
Researchers have discovered that it is not just molecular density, but also pattern and structural rigidity, that control super-selective binding interactions between nanomaterials and protein surfaces. The breakthrough could help optimize existing approaches to virus prevention and cancer detection.

The protein behind immunotherapy resistance
The protein behind immunotherapy resistance
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.

A chip to replace animal testing
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.

How Covid-19 Causes Neurological Damage
How Covid-19 Causes Neurological Damage
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.

Control of cell population sizes: When is enough enough?
Control of cell population sizes: When is enough enough?
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.

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, nutrition can help
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.
