Data-driven resistance training against muscular atrophy
Data-driven resistance training against muscular atrophy
Researchers at ETH Zurich and ZHAW present a simple method to precisely map resistance exercise on machines and record missing comparative figures. This could help to develop optimised training strategies in the future, such as for age-associated muscular atrophy. Muscles play a critical role in life.

Using magnetic worms to engineer nanoscale communication systems
Using magnetic worms to engineer nanoscale communication systems
Researchers at EPFL have shown that electromagnetic waves coupled to precisely engineered structures known as artificial ferromagnetic quasicrystals allow for more efficient information transmission and processing at the nanoscale. Their research also represents the first practical demonstration of Conway worms, a theoretical concept for the description of quasicrystals.

Bird Diversity in the Swiss Alps in Decline
Bird Diversity in the Swiss Alps in Decline
The diversity of bird communities in the Swiss Alps is declining more and more, a joint study of the University of Zurich and the Swiss Ornithological Institute has found. An analysis of data from the past two decades has revealed a loss of functional and compositional diversity in Alpine bird communities.

Brain 'signature' could help to diagnose schizophrenia
Brain ’signature' could help to diagnose schizophrenia
People with schizophrenia and their healthy siblings share patterns of brain activity that are different from those seen in individuals with no family history of the disorder, scientists from EPFL have found. Because the siblings do not show schizophrenia symptoms, this brain 'signature' could serve as a marker for the early diagnosis of the disorder.

Tiny fish under a giant camera
Tiny fish under a giant camera
Metal-based nanoparticles are a promising tool in medicine - as a contrast agent, transporter of active substances, or to thermally kill tumor cells. Up to now, it has been hardly possible to study their distribution inside an organism. Researchers at the University of Basel have used a three-dimensional imaging method to take high-resolution captures inside zebrafish embryos.

Cystic fibrosis: why so many respiratory complications?
Cystic fibrosis: why so many respiratory complications?
By demonstrating the key role of Vav3 protein, UNIGE researchers highlight how the protein Vav3 creates bacterial docking stations to facilitate lung infections in cystic fibrosis. Cystic fibrosis, one of the most common genetic diseases in Switzerland, causes severe respiratory and digestive disorders.

How Venus Flytraps also Snap
How Venus Flytraps also Snap
Venus flytraps are known for the fact that their catching leaves close in a flash when unsuspecting prey touch highly sensitive trigger hairs twice in a row. A team of researchers from ETH Zurich and the University of Zurich has now discovered a new snap mechanism. The Venus flytrap ( Dionaea muscipula ) is perhaps the most well-known carnivorous plant.

Cherned up to the maximum
Cherned up to the maximum
Topological materials are a new class of materials that could enable completely new types of electronic components and superconductors. In topological materials, electrons can behave differently than in conventional materials. The extent of these "exotic" phenomena depends on the so-called Chern number.

Transplantable lab-grown organs move a step closer
Transplantable lab-grown organs move a step closer
A liver organoid developed at EPFL offers new promise in transplantation and the study of liver disease. Biologists and bioengineers at EPFL have designed a new method for growing simplified human mini-livers. Their process is a potentially important breakthrough in the quest for transplantable lab-grown tissues.

Basel study: Why lopinavir and lopinavir and hydroxychloroquine do not work on Covid-19
Basel study: Why lopinavir and lopinavir and hydroxychloroquine do not work on Covid-19
Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. A research group from the University of Basel and the University Hospital has now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the virus.

Counting wheat heads for more ecology
Counting wheat heads for more ecology
To Achim Walter it's clear: the budding artificial intelligence will decisively advance agroecology. But before we can harvest the fruits of AI, computers still have a lot to learn. Over-fertilised fields, compacted soils, greenhouse gases and insect death - the list of problems in agroecology is both old and long.

How Venus Flytraps Snap
How Venus Flytraps Snap
Venus flytraps catch spiders and insects by snapping their trap leaves. This mechanism is activated when unsuspecting prey touch highly sensitive trigger hairs twice within 30 seconds. A study led by researchers at the University of Zurich has now shown that a single slow touch also triggers trap closure - probably to catch slow-moving larvae and snails.

Porous nitrogen-doped graphene ribbons for future electronics
Porous nitrogen-doped graphene ribbons for future electronics
A team of physicists and chemists has produced the first porous graphene ribbons in which specific carbon atoms in the crystal lattice are replaced with nitrogen atoms. These ribbons have semiconducting properties that make them attractive for applications in electronics and quantum computing, as reported by researchers from the Universities of Basel, Bern, Lancaster and Warwick in the Journal of the American Chemical Society.

The IRB discovers the activation mechanism of the "police patrol" cells of our immune system
Nearly 200 billion naïve T cells continuously patrol the human body in a dormant state, prepared to respond to potential threats. An international group of researchers, led by Dr. Roger Geiger of the Institute for Research in Biomedicine (IRB, affiliated to USI), demonstrated how these cells sustain a constant state of preparedness.

1.5 Billion People Will Depend on Water from Mountains
Global water consumption has increased almost fourfold in the past 100 years, and many regions can only meet their water demand thanks to essential contributions from mountain regions.

Evolutionary physiology and adaptation in the moor frog
Evolutionary physiology and adaptation in the moor frog
Organisms exposed to challenging environments face evolutionary pressure to adapt, which could lead to modifications in a variety of traits, such as morphology, physiology and behaviour. Katja Räsänen from the Swiss Federal Institute of Aquatic Science and Technology Eawag holds a deep interest in mechanisms of adaptation in natural populations.

Age-related impairments reversed in animal model
Age-related impairments reversed in animal model
Frailty and immune decline are two main features of old age. Researchers from the University of Bern and the University Hospital Bern now demonstrate in an animal model that these two age-related impairments can be halted and even partially reversed using a novel cell-based therapeutic approach. Elderly people are more prone to infectious diseases as the function of their immune system continuously declines with progression of age.

Structural insights into Fe-S protein biogenesis
Structural insights into Fe-S protein biogenesis
The cytosolic iron sulfur assembly (CIA) pathway is required for the insertion of Fe-S clusters into proteins, including many DNA replication and repair factors. Despite its essential cellular function, this pathway remains enigmatic. A new integrative structural and biochemical study from the Thomä group now provides detailed insights into the mechanisms of Fe-S protein biogenesis.

Outsmarting self-organization
Outsmarting self-organization
Researchers at ETH Zurich have coaxed tiny spheres made of polymer gels into forming complex patterns by themselves through a two-step process. Surfaces with tailor-made optical and mechanical properties could be realized in this way. When retiling the bathroom or the terrace using, for instance, square, rectangular or hexagonal tiles, the result will be a simple and regular pattern - assuming one doesn't make any mistakes.
