The ozone layer is on track to recover within four decades, with the global phase-out of ozone-depleting chemicals already benefitting efforts to mitigate climate change.
In theory, the genetic diversity of populations should decrease as they expand across space. But this is not true for bacteria. Researchers at Eawag are now showing that fungi play an important role in this context. They make it easier for bacteria to spread and thus also promote genetic exchange between different bacteria.
Researchers have long suspected a link between bed occupancy and mortality in hospitals. Now, a study by the University of Basel has provided the missing data, revealing that smaller hospitals reach their capacity limit much earlier.
A robotic microsurgeon reveals how embryos grow
Combining biology and robotics, scientists at EPFL have built a robotic microsurgery platform that can perform high-precision, micrometer-resolution dissections to advance our understanding of how the vertebrate body forms during embryonic development. Understanding the biology behind an embryo's development is crucial not only from a basic science perspective, but also from a medical one.

The world could lose over 40 percent of its total glacier mass and 80 percent of all individual glaciers this century. Depending on how successful efforts to curb the climate crisis are, it could be "only" a quarter. This is reported today in the journal Science by an international research team with participation from the Swiss Federal Institute for Forest, Snow and Landscape Research WSL.
Scientists at EPFL and Heriot-Watt University have developed a machine learning approach to accurately predict potentially harmful amine emissions from carbon-capturing plants. Global warming is partly due to the vast amount of carbon dioxide that we release, mostly from power generation and industrial processes, such as making steel and cement.
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.
Trees absorb tiny metal particles from the air and soil and deposit them in their tissues. This has been shown by an experiment conducted by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL. These findings open up possibilities for detecting environmental pollution or even remedying it in the future.
A team from the University of Geneva deciphers how negative emotions durably modify brain activity in the older adults . Negative emotions, anxiety and depression are thought to promote the onset of neurodegenerative diseases and dementia. But what is their impact on the brain and can their deleterious effects be limited? Neuroscientists at the University of Geneva observed the activation of the brains of young and older adults when confronted with the psychological suffering of others.
EPFL chemical engineers have invented a solar-powered artificial leaf, built on a novel electrode which is transparent and porous, capable of harvesting water from the air for conversion into hydrogen fuel. The semiconductor-based technology is scalable and easy to prepare. A device that can harvest water from the air and provide hydrogen fuel-entirely powered by solar energy-has been a dream for researchers for decades.
Our body is made of billions of cells that have the same overall genome but play specialized roles to create different tissues and organs. Working in a freshwater invertebrate, FMI researchers found that a protein called Zic4 drives the formation and maintenance of the tentacles that surround the animal's mouth.
Evolution, health, and animal and human behavior were among the topics of the most popular 10 media releases from the University of Zurich in 2022. The communiqué with the greatest reach was about a damaged liver successfully treated outside of the human body and then used in a donor organ transplant.
Researchers have developed a modular system for the simple and inexpensive production of security inks. It is based on polymers and could also be used in solar power plants and screens in the future. Novel fluorescent dyes developed by researchers are relatively simple and inexpensive to produce. The dyes are polymers with a modular structure.
Does life exist elsewhere in the universe? There's a good chance it does - though it might look very different to life on Earth. Scientists may soon be able to offer a definitive answer. Twenty-seven years ago, at the University of Geneva, Michel Mayor and Didier Queloz - now a professor at ETH - discovered the first extrasolar planet orbiting a Sun-like star.
