Geologically vibrant continents produce higher biodiversity
Using a new mechanistic model of evolution on Earth, researchers at ETH Zurich can now better explain why the rainforests of Africa are home to fewer species than the tropical forests of South America and Southeast Asia. The key to high species diversity lies in how dynamically the continents have evolved over time.

The defensive arsenal of plant roots
The defensive arsenal of plant roots
A team from the University of Geneva has discovered the mechanisms that regulate the formation of the protective layer of plant roots. Plants adapt to their nutritional needs by modifying the permeability of their roots through the production or degradation of a cork-like layer called suberin. By studying the regulation of this protective layer in Arabidopsis thaliana , an international team, led by scientists from the University of Geneva , Switzerland, has discovered four molecular factors responsible for the genetic activation of suberin.

Detecting dementia in the blood
Detecting dementia in the blood
Empa researcher Peter Nirmalraj wants to image proteins with unprecedented precision - and thus gain insights into the molecular pathogenesis of Alzheimer's. This should pave the way for an earlier diagnosis of the dementia disorder via a simple blood test. Together with neurologists from the Kantonsspital St.Gallen, a successful pilot study has now been completed.

Cells, cylinders and a vision of the future
Cells, cylinders and a vision of the future
The "gene scissors" CRISPR/Cas9 can be used to precisely modify genes in order to study their function in an organism. A researcher at Eawag has now succeeded for the first time in establishing the gene scissors for a fish cell line of rainbow trout. This means that, as of now, genetically modified cell lines can be produced.

How tactile vibrations create illusions
How tactile vibrations create illusions
Researchers from the University of Geneva and UNIFR decipher how the amplitude and frequency of tactile vibrations can bias how the brain interprets them. Among the traditional five human senses, touch is perhaps the least studied. Yet, it is solicited everywhere, all the time, and even more so in recent years with the widespread daily use of electronic devices that emit vibrations.

A Glimpse into the ocean's biological carbon pump
A Glimpse into the ocean’s biological carbon pump
Oceans absorb carbon dioxide from the atmosphere through microscopic algae that carry out photosynthesis and then sink to the deep sea when they die. This sinking enhances the degradation processes, as researchers have now discovered. Oceans play a key role in the global carbon dioxide balance. This is because billions of tiny algae live there, absorbing carbon dioxide through photosynthesis and incorporating it into their biomass.

Very old Universe reveals new galaxies
Very old Universe reveals new galaxies
Scientists serendipitously discover two heavily dust-enshrouded galaxies that formed when the Universe was only 5% of its present age. While investigating the data of young, distant galaxies observed with the Atacama Large Millimeter/submillimeter Array, Yoshinobu Fudamoto from Waseda University and the National Astronomical Observatory of Japan noticed unexpected emissions coming from seemingly empty regions in space that, a global research team confirmed, came actually from two hitherto undiscovered galaxies heavily obscured by cosmic dust.

Simplifying quantum systems
Simplifying quantum systems
If only it were less prone to error, quantum physics might already be giving us instant solutions to seemingly unsolvable problems. researchers are therefore working to develop systems that are more robust. In crude terms, our digitally driven information society is based on a simple binary opposition: 0 or 1.

The whole is the truth
Quantum physics opens our eyes to the holistic nature of reality. Nothing can be observed in isolation - and everything is governed by chance. We generally assume that the objects around us exist independently of us and of other objects. We can observe a glass as a well-defined object and investigate its chemical or physical properties in the lab.

Fibres make chaotic turbulence more predictable
Fibres make chaotic turbulence more predictable
The chaotic behaviour of vortices is one of the things that makes weather forecasting so difficult. Researchers at ETH Zurich have now developed a novel experimental method that enables more accurate analyses of the movement of turbulence in fluids. Turbulence is one of the most important and at the same time one of the least understood phenomena in nature.

Improving leukemia therapy with targeted treatment approaches
In chronic leukemias, blocking the overactive kinase JAK2 by a targeted therapy approach is only mitigating the patients' symptoms, but cannot truly change the course of the disease. A study by the University of Basel has shown that it may be possible to improve the therapeutic effects by additionally inhibiting a specific signaling pathway.

New immunotherapy method turns activated specifically in tumor
New immunotherapy method turns activated specifically in tumor
Scientists have developed a chemical method for targeting the effects of cancer-fighting immunotherapy drugs only to the tumor tissue, making the drugs less toxic to the rest of the human body. Immunotherapy drugs are promising new weapons in the fight against cancer, but they are so strong that they can be toxic to the rest of the human body.

Acoustic illusions
Acoustic illusions
Researchers have devised an ingenious method of using acoustics to conceal and simulate objects. When listening to music, we don't just hear the notes produced by the instruments, we are also immersed in its echoes from our surroundings. Sound waves bounce back off the walls and objects around us, forming a characteristic sound effect - a specific acoustic field.

How serotonin curbs cocaine addiction
How serotonin curbs cocaine addiction
By identifying the role of serotonin during cocaine use, scientists explain why only one in five persons becomes addicted to this drug. Contrary to common thinking, cocaine triggers an addiction only in 20% of the consumers. But what happens in their brains when they lose control of their consumption? Thanks to a recent experimental method, neuroscientists at the University of Geneva , Switzerland, have revealed a brain mechanism specific to cocaine, which has the particularity of triggering a massive increase in serotonin in addition to the increase in dopamine common to all drugs.

Reusing shower water
Reusing shower water
An Eawag study has shown that it makes good sense to recover domestic energy, for example from warm shower water. The study refutes concerns that this form of heat utilisation could have a negative impact on waste water treatment plants. In fact, utilising the energy closer to its source reduces energy losses in the waste-water system.

Risky or not? What is driving the polarization surrounding 5G?
Risky or not? What is driving the polarization surrounding 5G?
When questions about the risks and benefits of new technology split society, objective discussion becomes difficult. A University of Basel researcher investigated this kind of polarization using the example of perception of the risk posed by 5G. The research suggests how divergent risk perceptions may arise and how excessive polarization can potentially be countered in the future.
