A swarm of 3D printing drones for construction and repair
A swarm of 3D printing drones for construction and repair
An international research team led by drone expert Mirko Kovac of Empa and Imperial College London has taken bees as a model to develop a swarm of cooperative, 3D-printing drones. Under human control, these flying robots work as a team to print 3D materials for building or repairing structures while flying, as the scientists report in the cover story of the latest issue of Nature.

Genetics and diet influence bile acid homeostasis
Genetics and diet influence bile acid homeostasis
Scientists have used a systems genetics approach to unravel novel genetic and environmental modulators of bile acid homeostasis. Their findings provide new insights into the regulatory mechanisms of bile acid homeostasis and may have implications for the treatment of metabolic diseases. Image: Circos plot summarizing the bile acid species quantified in different biological compartments, their changes, correlation and associations with quantitative trait loci in two different diets.

Cilia in 3D: Miniature train station discovered
Cilia in 3D: Miniature train station discovered
Cilia are small hair-like organelles that extend from cells and perform many functions, including motility and signaling. Researchers have now revealed that cilia have a specialized transport hub at their base, where trains and cargos are assembled for transport throughout the cilia. Since defects in this cilia transport system can lead to e.g. cystic kidneys or blindness, the results published in Science also provide new insights into molecular basis for a variety of diseases.

Diabetes: when circadian lipid rhythms go wrong
Diabetes: when circadian lipid rhythms go wrong
A team from Geneva, Switzerland, shows that the disruption of lipid temporal profiles in type 2 diabetes stiffens the membrane of pancreatic endocrine cells, which could alter their function. Like all living beings, human physiological processes are influenced by circadian rhythms. The disruption of our internal clocks due to an increasingly unbalanced lifestyle is directly linked to the explosion in cases of type 2 diabetes.

Awakening 'dormant' cells to fight cancer
Awakening ’dormant’ cells to fight cancer
A team from the UNIGE and the HUG has succeeded in identifying a drug-targetable mechanism whose blockage reduces the capacity of melanoma cells to adapt and resist to treatment. The advent of small-molecule targeted therapies, a decade ago, revolutionized the treatment of metastatic melanoma, provided that the tumors carry the mutations to respond to these treatments.

Nanotubes illuminate the way to living photovoltaics
Nanotubes illuminate the way to living photovoltaics
Scientists at EPFL have gotten bacteria to spontaneously take up fluorescent carbon nanotubes for the first time. The breakthrough unlocks new biotechnology applications for prokaryotes, such as near-infrared bacteria tracking and "living photovoltaics" - devices that generate energy using light-harvesting bacteria.

Science Publication: SARS-CoV-2 Genomic Surveillance in Africa
A new study in Science shows how the rapid expansion of genomic surveillance in Africa allowed the continent to describe the introduction and spread of SARS-CoV-2 variants in African countries. Swiss TPH contributed to these efforts as part of the SARS-CoV-2 surveillance programme in Equatorial Guinea.

Immunotherapy Reduces Lung and Liver Fibrosis in Mice
Immunotherapy Reduces Lung and Liver Fibrosis in Mice
Chronic diseases often lead to fibrosis, a condition in which organ tissue suffers from excessive scarring. Researchers at the University of Zurich have now developed an immunotherapy that specifically targets the cause - activated fibroblasts - while leaving normal connective tissue cells unharmed.

Why densification often fails due to acceptance
Why densification often fails due to acceptance
Today, densification is a principle of urban development. Nevertheless, it repeatedly encounters local resistance. ETH spatial scientists: inside have now systematically investigated in six world cities and in the canton of Zurich how the acceptance of densification can be explained among the population.

A window into the fruit fly's nervous system
A window into the fruit fly's nervous system
Scientists at EPFL have developed an implantation technique that allows unprecedented optical access to the "spinal cord" of the fruit fly, Drosophila melanogaster. This work can potentially lead to breakthroughs in the fields of neuroscience, artificial intelligence, and bio-inspired robotics. Understanding biological motor control requires the ability to record neural activity while animals are behaving," says Professor Pavan Ramdya at EPFL's School of Life Sciences.

When innuendo is no longer heard
Ironic remarks or indirect requests are part of our everyday dialogue. But certain brain lesions can alter the grasp of the hidden meaning of these expressions. During her PhD, speech therapist Natacha Cordonier studied these disorders, from diagnosis to treatment. Exclaiming 'What a great weather! during a picnic, when the weather is rainy.

Intelligent microscopes for detecting rare biological events
EPFL biophysicists have developed control software that optimizes how fluorescence microscopes collect data on living samples. Their control loop, used to image mitochondrial and bacterial sites of division in detail, is released as an open source plug-in and could inspire a new generation of intelligent microscopes.

A warm intrusion in the Arctic causes extreme pollution levels
During the MOSAiC research expedition, conducted in the Arctic pack ice between 2019 and 2020, scientists observed an atmospheric perturbation triggered by the intrusion of a highly polluted warm air-mass. A first study providing further insight into the phenomenon and its potential implications has just been published.

A thousand days of CHEOPS
A thousand days of CHEOPS
The Swiss space telescope CHEOPS will celebrate its 1000th day in orbit around the Earth on Tuesday 13 September. Its excellent condition will allow it to remain active for several more years. After 1000 days in orbit around the Earth, the CHEOPS space telescope shows almost no signs of wear. Under these conditions, it could continue to reveal the fascinating details of many exoplanets for many years to come.

Longer, Hotter and More Frequent Heat Waves in Swiss Cities
Longer, Hotter and More Frequent Heat Waves in Swiss Cities
Hot days followed by sweltering nights without any temperature relief in between might become a new norm towards the end of the 21st century. Researchers from the University of Zurich have analyzed the frequency, intensity and length of such extreme events for five Swiss cities. Lugano and Geneva would be most affected.

With these trends, Europe’s agriculture must reckon
Climate change, environmental and animal welfare policies, ageing farmers: Europe's agriculture is facing enormous challenges, which vary diametrically depending on the region. Where will farming soon become unprofitable? Where are laws forcing them to change their practices? A study co-led by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL has now investigated this for all of Europe.

Two new rocky worlds around an ultra-cool star
An international research team, with the participation of the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS, discovered two "super-Earth" exoplanets. One is located at just the right distance from its star to potentially hold liquid water on its surface. Most of the planets that have been discovered around other stars - also known as exoplanets - are bad candidates for life as we know it.

Stressed mitochondria help cells survive respiratory infections
Stressed mitochondria help cells survive respiratory infections
Mildly stressing mitochondria with an antibiotic can increase tolerance against respiratory infections, shows a study by scientists at EPFL. Many respiratory infections, such as influenza or COVID-19 add significant stress to cells and organs, which can lead to acute respiratory distress syndrome (ARDS), which itself can eventually cause death in aged or sensitive individuals.
