The human scream signals more than fear of imminent danger or entanglement in social conflicts. Screaming can also express joy or excitement. For the first time, researchers at the University of Zurich have demonstrated that non-alarming screams are even perceived and processed by the brain more efficiently than their alarming counterparts.

Researchers from the Oeschger Centre for Climate Change Research at the University of Bern reconstructed for the first mean ocean temperatures over the last 700,000 years using ice core data. The new knowledge serves to improve our understanding of the climate system. Bern's ice core researchers were already able to demonstrate in 2008 how the concentration of CO2 in the atmosphere has changed over the past 800,000 years.

Parkinson's disease: wearable sensors to track symptoms
Scientists have developed algorithms that, combined with wearable sensors, could help clinicians to monitor the progression of Parkinson's disease and assess the effects of medications commonly used by people with this neurodegenerative disorder. Parkinson's disease affects neurons in an area of the brain that controls movement, causing tremors, difficulty walking and other motor problems.

Tree hydraulics and water relations: why trees die as a result of drought
When trees die during a period of drought, they die of thirst. Researchers from the University of Basel have demonstrated in a field study that a rapid collapse in the hydraulic system is responsible for tree death. And they found out that the trees possibly die more rapidly than previously thought.

Joyful Screams Perceived More Strongly than Screams of Fear or Anger
The human scream signals more than fear of imminent danger or entanglement in social conflicts. Screaming can also express joy or excitement. For the first time, researchers at the University of Zurich have demonstrated that non-alarming screams are even perceived and processed by the brain more efficiently than their alarming counterparts.

The protection of genome integrity of germ cells is essential for animal fertility. Researchers from the Grosshans group characterized a defense mechanism against selfish genetic elements in the C. elegans germline. They identified a protein processing mechanism that controls the activity of small RNAs to achieve specific silencing of transposons while sparing endogenous genes.
Cognitive motor training helps in the fight against Alzheimer's and dementia, as demonstrated for the first time in a study by an international team of researchers with ETH Zurich involvement. The training platform used was developed by an ETH Zurich spin-off. A dementia diagnosis turns the world upside down, not only for the person affected but also for their relatives, as brain function gradually declines.
A new study published in Science Translational Medicine by EPFL professor Johan Auwerx and scientists from EPFL start-up Amazentis highlights the effectiveness of mitophagy-stimulating molecule Urolithin A in mice to cure a disease similar to Duchenne Muscular Dystrophy. And points to a possible treatment for affected people.
Veal calf fattening: it can work with less antibiotics
By adopting a few simple measures, farmers can drastically reduce the use of antibiotics and improve the well-being of their animals without economic disadvantages. This was confirmed in a field trial- the first of its kind in Switzerland - carried out by researchers of the University of Bern based on the specially developed "outdoor veal calf" method.

The human brain as we know it today is relatively young. It evolved about 1.7 million years ago when the culture of stone tools in Africa became increasingly complex. A short time later, the new Homo populations spread to Southeast Asia, researchers from the University of Zurich have now shown using computed tomography analyses of fossilized skulls.
The US research laboratory "Fermilab" has published the eagerly awaited results of the experimental measurement of the so-called anomalous magnetic dipole moment of the muon. As members of the "Muon g-2 Theory Initiative", researchers from the University of Bern have calculated the same physical quantity theoretically in parallel, based on the Standard Model.
Conspiracy theories appear to be increasing in popularity as the Covid-19 pandemic continues. But to what extent do people really agree with them, and what is the association with cognitive biases? A research team from the University of Basel studied these questions in German-speaking Switzerland and Germany.
Scientists have developed AI-powered nanosensors that let researchers track various kinds of biological molecules without disturbing them. The tiny world of biomolecules is rich in fascinating interactions between a plethora of different agents such as intricate nanomachines (proteins), shape-shifting vessels (lipid complexes), chains of vital information (DNA) and energy fuel (carbohydrates).
Researchers at ETH Zurich have developed fluorescent polymers whose colour can be easily tuned. Depending on their length, the polymers emit a different colour. Potential applications include biomedicine, security printing and solar energy. Around the world, a huge amount of research and development work is currently being done on carbon-containing, or organic, molecules that emit coloured light after appropriate excitation.
Researchers from the University of Geneva have discovered a very small protein in Drosophila that plays a key role in how females select the semen that will fertilize its eggs when it mates with several males. Even a well-characterized genome, such as that of the Drosophila the so-called fruit fly, still holds surprises.
Scientists, together with local startup L2F, have developed a robust model that can predict when a systemic shift is about to occur, based on methods from a branch of mathematics called topological data analysis. Topological data analysis (TDA) involves extracting information from clouds of data points and using the information to classify data, recognize patterns or predict trends, for example.
Strongyloidiasis, a parasitic worm infection caused by soil-transmitted helminths, remains a neglected public health problem with limited treatment options. Swiss TPH researchers conducted the first dose-finding study with moxidectin against strongyloidiasis. The drug could become a treatment alternative to the only treatment available so far and help fill the empty anthelminthic drug pipeline.
The ease of creating fake virtual identities plays an important role in shaping the way information - and misinformation - circulates online. Could 'pseudonym' parties, that would verify proof of personhood not proof of identity, resolve this tension' Social media platforms have completely changed the way information flows online.
The results could help clinicians understand addiction and enable people to better manage substance withdrawal Geneva & Lausanne, Switzerland - Cocaine is a highly addictive substance that, in the long term, can have adverse effects on health and wellbeing. There are around 18 million cocaine users globally, according to a UN report.
