Researchers found that in mice, long-lived embryonic macrophages in the lungs die upon aging and during infection and are replaced by inflammatory bone marrow-derived macrophages. This causes severe disease progression when infected with viral flu. Lung infections with the influenza virus or a coronavirus more frequently result in severe disease progression in older people.
Researchers from ETH Zurich have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than average - or too wet. Many people are familiar with the hole in the ozone layer over Antarctica, but what is less well known is that occasionally, the protective ozone in the stratosphere over the Arctic is destroyed as well, thinning the ozone layer there.
On 15 September, after a two-year hiatus due to the pandemic, an Eawag Info Day will be held once again, dedicated to new technologies for monitoring surface waters. Physicist Damien Bouffard, Head of the Aquatic Physics Group at Eawag, was involved in its conception and explains in an interview what new opportunities and challenges these technologies bring.
Copper exposure in the environment and the protein alpha-synuclein in the human brain could play an important role in the pathogenesis of Parkinson's disease. A team from Empa and the University of Limerick was able to show how the protein takes on an unusual shape when exposed to large amounts of copper ions.
If timetables and punctuality are an integral part of our society, it has not always been so. This is what Catherine Herr-Laporte, a doctoral student at the Chair in the History of Technology, has shown by studying the development of postal transport in France throughout the 18th century as part of her doctoral thesis on time and mobility.
Gestures Can Improve Understanding in Language Disorders
When words fail, gestures can help to get the message across - especially for people who have a language disorder. An international research team has now shown that listeners attend the gestures of people with aphasia more often and for much longer than previously thought. This has implications for the use of gestures in speech therapy.

Making CRISPR hype more of a reality
The latest CRISPR-based genome editing systems function more like molecular taxis rather than a pair of molecular scissors. This makes them much safer for patients who will soon benefit from gene therapies, as Eric Aird explains. This year we celebrate 10 years of genome editing with CRISPR. The system is often referred to as molecular scissors, and this designation is quite accurate for its first applications.

A team of researchers led by the University of Bern has for the first time identified an unexpected richness of complex organic molecules at a comet. This was achieved thanks to the analysis of data collected during ESA-s Rosetta mission at comet 67P/Churyumov-Gerasimenko, also known as Chury. Delivered to the early Earth by impacting comets, these organics may have helped to kick-start carbon-based life as we know it.
Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human body. Researchers from Paul Scherrer Institute PSI, EPF Lausanne (EPFL), and the University of Geneva describe the new method in the scientific journal Nature Photonics .
By comparing the neutralisation capacity induced by the different variants of SARS-CoV-2, a team from the UNIGE and the HUG reveals the exceptional capacity of Omicron to evade our immunity. The current wave of COVID-19 highlights a particularly high risk of reinfection by the Omicron variant of SARS-CoV-2.
Geneva, 4 July 2022. Ten years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the Higgs boson predicted by the Standard Model of particle physics. The discovery was a landmark in the history of science and captured the world's attention.
The World Health Organization (WHO) recently listed a new sibling diagnosis for post-traumatic stress disorder (PTSD), termed complex post-traumatic stress disorder (CPTSD). An international team with the involvement of the University of Zurich has now summarized the symptoms of the long-awaited new diagnosis and issued guidelines for clinical assessment and treatment.
Biodiversity is beautiful, but it-s also vitally important. researchers are getting to the heart of how species diversity and genetic diversity evolve - and why we must fight to preserve them. Spring is synonymous with bright yellow dandelions, lush green fields and cloudless blue skies, a captivating combination of colours that sends many people into raptures of delight.
Even before carbohydrates reach the bloodstream, the very sight and smell of a meal trigger the release of insulin. For the first time, researchers from the University of Basel and University Hospital Basel have shown that this insulin release depends on a short-term inflammatory response that takes place in these circumstances.
NASA's Double Asteroid Redirection Test (DART) mission is the world's first full-scale planetary defense test against potential asteroid impacts on Earth. Researchers of the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS now show that instead of leaving behind a relatively small crater, the impact of the DART spacecraft on its target could leave the asteroid near unrecognizable.
As early as the Neolithic period, pests posed a threat to agricultural yields, as shown by the remains of mice and insects found in prehistoric wells by a Basel-led archaeological research team. However, there are also indications that people knew how to defend against these pests - for example, by switching to less vulnerable kinds of grain.
Coordinated by the CSEM, the large European quantum project macQsimal, included in the FET Flagship on Quantum Technologies initiative, is nearing its end and reveals very promising results.
Scientists have developed a new, PET-like plastic that is easily made from the non-edible parts of plants. The plastic is tough, heat-resistant, and a good barrier to gases like oxygen, making it a promising candidate for food packaging. Due to its structure, the new plastic can also be chemically recycled and degrade back to harmless sugars in the environment.
Opioid poisoning on the rise
Researchers at ETH have shown that cases of opioid poisoning and the prescription of opioids have increased sharply in Switzerland over the past 20 years. Although the situation is not as serious as in North America, the risk should not be underestimated. Since the early 2000-s the US has been in the grip of an opioid crisis that has been exacerbated by the Covid pandemic - in 2021, more than 100,000 people died of an opioid overdose in the country.

Infants undergoing heart surgery are connected to a heart-lung machine and given nitric oxide as an anti-inflammatory. Researchers from the Universities of Zurich and Queensland have now conducted the world's largest study of its kind, showing that using nitric oxide does not improve children's recovery after surgery.
