A human model for autism
The CRISPR-Cas gene scissors enable researchers to study the genetic and cellular causes of autism in the lab - directly on human tissue. How does autism develop? Which genes and cells in the human brain contribute to it? A new brain organoid model allows researchers from the Department of Biosystems at ETH Zurich in Basel and colleagues from Vienna to investigate these questions in human cells.

The discovery of a new kind of cell revolutionizes neuroscience
A research team from the University of Lausanne and the Wyss Center has discovered a new type of cell essential to brain function. Hybrid in composition and function between the two hitherto known types of brain cells - neurons and glial cells - these cells of a new order are found in several brain regions from mice to humans.

Analog & digital: best of both worlds in one energy-efficient system
The fusion of 2D semiconductors and ferroelectric materials could lead to joint digital and analog information processing, with significant improvement in energy consumption, electronic device performance, and lead to novel functionalities. We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary code, breaking the information into bits.

Reversing aging in the blood and immune systems
As we age, our bodies face many challenges, including declining immune system function and increased vulnerability to various health problems. A study conducted within the UNIL-CHUV Department of Oncology has recently shed light on these challenges. It unveils a potential solution that could have far-reaching implications for aging individuals.

Deciphering the ’highway code’ of our cells
A team from the University of Geneva has identified a key mechanism in the regulation of microtubules, the internal communication pathways of our cells. Cancers, degenerative diseases: deregulation of our cells' internal communication pathways is at the root of many conditions. Microtubules - microscopic protein filaments - play a crucial role in controlling these exchanges.

First Experimental Release of Parasitic Asian Wasp to Control Spotted-Wing Drosophila
The invasive spotted-wing drosophila (SWD) is a devastating pest in berry, stone fruit and grape crops. A natural antagonist from the fruit fly-s area of origin in East Asia is now due to be released in Switzerland for the first time by Agroscope and CABI. The experimental releases in the Cantons of Jura and Ticino aim to clarify whether this parasitic wasp can become established in Switzerland to regulate the SWD population and reduce production losses.

How fungal infections cause blood poisoning
Blood poisoning caused by a fungal infection is a severe, life-threatening condition. Researchers at the University of Bern have now discovered a mechanism that helps a yeast fungus to spread more easily within the body. The immune system, of all things, plays a major role in this process. These findings could open up new therapeutic avenues for blood poisoning caused by yeast, but also for other invasive fungal infections.

Cells with an ear for music release insulin
"We will rock you": researchers are developing a gene switch that triggers insulin release in designer cells by playing certain rock and pop songs. Diabetes is a condition in which the body produces too little or no insulin. Diabetics thus depend on an external supply of this hormone via injection or pump.

How Salmonella grow together in the gut and exchange antibiotic resistance
The ability to utilize a mere single alternative food source is all it takes for diarrhoea causing Salmonella bacteria to bloom when a gut is already colonized by a closely related strain, according to researchers from ETH Zurich. This coexistence enables the exchange of antibiotic resistance. Bacteria are growing more resistance to common antibiotics, and one key factor contributing to this problem is the exchange of antibiotic resistance genes between closely related bacterial strains.

Building muscle in the lab
A new method allows large quantities of muscle stem cells to be safely obtained in cell culture. This provides a potential for treating patients with muscle diseases - and for those who would like to eat meat, but don't want to kill animals. ETH Zurich Professor Ori Bar-Nur and his team grow muscle cells in the laboratory.

Study undermines evolutionary rule
According to Cope's rule, today's animal species are on average larger than older species of the same genus. A large-scale study led by a researcher at the University of Fribourg has just demonstrated that this is not the case in turtles . Paleontologists have noticed that, in the course of their evolution, certain species tend to get bigger and bigger.

Substances from corn roots influence wheat yields
Corn roots secrete certain substances that affect the quality of the soil. In certain fields, this effect increases the yield of wheat planted after corn in the same soil by more than 4%. This has been demonstrated by researchers at the University of Bern. Although the findings from several field experiments show that such effects are highly variable, they could nevertheless contribute in the long term to making the cultivation of cereals more sustainable without additional fertilizers or pesticides.

How immunity contributes to ageing and neurodegeneration
Researchers at EPFL have found that a specific immune signaling pathway drives ageing-related inflammation and neurodegeneration. The work can help us understand the mechanisms behind ageing-associated impairment and disease. As we age, our bodies undergo various changes that can impact our overall health and make us more susceptible to diseases.

How the microbiome drives the evolution of immune defenses
A new study from researchers at EPFL reveals how bacteria shape the immune system of fruit flies, shedding light on the evolution of host defenses against specific pathogens and beneficial microbes. Animals and humans coexist with a vast array of microorganisms known as the microbiome, forming an intricate relationship that can range from mutually beneficial to pathogenic.

The secrets of folding DNA
A study published on August 2, 2023 in "Cell" by a team from the University of Lausanne reveals that the way DNA folds back on itself directly influences the development and functioning of the nervous system. DNA is like a thread of wool which, during development, twists around itself to form a chromosome, a ball of yarn.

Learning how to control HIV from African genomes
A study on almost 4000 people of African descent has identified a gene that acts as natural defense against HIV by limiting its replication in certain white blood cells. An international effort co-led by EPFL, Canada's National Microbiology Laboratory, and Imperial College London, it paves the way for new treatment strategies.

Organoids revolutionize research on respiratory infections
In a breakthrough for bioengineering, researchers at EPFL have developed organoids that can model the human respiratory tract. The organoids, called AirGels, allow them to uncover the mechanism by which antibiotic-resistant pathogens like Pseudomonas aeruginosa infect the respiratory tract. Biofilms are highly resistant communities of bacteria that pose a major challenge in the treatment of infections.
