Glacier shrinkage is causing a 'green transition'
Glacier shrinkage is causing a ’green transition’
Glacier-fed streams are undergoing a process of profound change, according to scientists in a paper appearing in Nature Geoscience. This conclusion is based on the expeditions to the world's major mountain ranges by members of the Vanishing Glaciers project. Microbial life will flourish in mountain streams because of ongoing glacier shrinkage.

The 'switch' that keeps the immune system from attacking the body
The ’switch’ that keeps the immune system from attacking the body
Scientists at EPFL uncover the mechanism by which cells mark the protein cGAS for degradation, which is critical in preventing the immune system from mistakenly attacking the body's own tissues. A microscopic battle rages in our bodies, as our cells constantly fend off invaders through our immune system, a complex system of cells and proteins designed to protect us from harmful pathogens.

Arterial Connections Improve Treatment Outcomes Following Stroke
Arterial Connections Improve Treatment Outcomes Following Stroke
Blood vessels that cross-connect adjacent arterial trees regulate blood flow to the brain in stroke patients. Researchers at the University of Zurich have now shown that these vessels prevent brain hemorrhage following treatment to remove blood clots. They play a crucial role in the recovery of stroke patients.

Cracking the Code of Neurodegeneration
Cracking the Code of Neurodegeneration
Scientists at the University of Zurich have developed an innovative neural cell culture model, shedding light on the intricate mechanisms underlying neurodegeneration. Their research pinpointed a misbehaving protein as a promising therapeutic target in the treatment of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

Bio-inspired neuroprosthetics: sending signals the brain can understand
Bio-inspired neuroprosthetics: sending signals the brain can understand
Prostheses that connect to the nervous system have been available for several years. Now, researchers at ETH Zurich have found evidence that neuroprosthetics work better when they use signals that are inspired by nature. A few years ago, a team of researchers working under Professor Stanisa Raspopovic at the ETH Zurich Neuroengineering Lab gained worldwide attention when they announced that their prosthetic legs had enabled amputees to feel sensations from this artificial body part for the first time.

What can bulls tell us about men?
What can bulls tell us about men?
Researchers have found genes in the reproductive organs of bulls that influence fertility. The findings can be transferred to humans, as these genes are also present in men. Infertility is a widespread problem: worldwide, one in eight couples fail to fulfil their desire to have children within a year - or even at all.

Protein modifications key influencers in neurodegenerative diseases
Protein modifications key influencers in neurodegenerative diseases
Exploring the post-translational modifications of a key protein in Parkinson's disease, researchers at EPFL and USC uncover potential pathways for future therapies in neurodegenerative diseases in general. Neurodegenerative diseases, such as Alzheimer's and Parkinson's, present a significant health challenge, affecting over 50 million people globally.

First Swiss Field Trial with CRISPR/Cas9-Modified Barley
First Swiss Field Trial with CRISPR/Cas9-Modified Barley
Agroscope has been granted approval by the Federal Office for the Environment for a field trial with spring barley. The focus is on a barley gene that has been disabled by new breeding techniques. The trial, which will be launched in spring 2024 on the Protected Site in Zurich-Reckenholz and will run for three years, aims to determine whether yields can be increased in this manner.

Asexual Propagation of Crop Plants Gets Closer
Asexual Propagation of Crop Plants Gets Closer
When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered without fertilization, as researchers have shown. Their findings open up new avenues for the asexual propagation of crop plants.

Rare retinal diseases: detective work for the eyesight
Rare retinal diseases: detective work for the eyesight
A team at the Institute of Molecular and Clinical Ophthalmology Basel (IOB) and the University of Basel is hunting for the causes of hereditary retinal diseases.

Mechanism for reducing age-related neuroinflammation
As we age, our cells lose the ability to effectively eliminate the waste products they produce. This degeneration has serious consequences as it can cause inflammation and dysfunction throughout the body. A team of scientists at the University of Freiburg has now discovered that a specific drug treatment can alleviate this condition by stimulating a mechanism called mitophagy .

Stress Influences Brain and Psyche Via Immune System
Stress Influences Brain and Psyche Via Immune System
Chronic stress affects the immune system and the brain. researchers now show that a particular enzyme found in cells of the immune system enters the brain under stress. In mice, it causes them to withdraw and avoid social contact. This newly discovered connection between body and mind in stress-related mental illnesses could lead to new treatments for depression.

A machine learning framework that encodes images like a retina
A machine learning framework that encodes images like a retina
Researchers have developed a machine learning approach to compressing image data with greater accuracy than learning-free computation methods, with applications for retinal implants and other sensory prostheses. A major challenge to developing better neural prostheses is sensory encoding: transforming information captured from the environment by sensors into neural signals that can be interpreted by the nervous system.

Spiky insight: How red blood cells deform
Spiky insight: How red blood cells deform
Researchers have observed living red blood cells transforming into spiky "echinocytes" in real time when treated with high concentrations of ibuprofen using holotomographic microscopy and displayed them in 3D renderings. Blood is indeed "a juice of rarest quality." What the poet and natural scientist Goethe already suspected can now actually be visualized using innovative imaging techniques.

Scientists successfully simulate protein complex that initiates fertilisation
Scientists successfully simulate protein complex that initiates fertilisation
Researchers at ETH Zurich recently developed highly realistic simulations of the proteins on sperm and egg cells coupling together before they fuse. These findings enabled the research team to solve several mysteries of fertilisation at once, which could help to accelerate development of more targeted infertility treatments.

Resistant bacteria can remain in the body for years
Resistant bacteria can remain in the body for years
Fighting disease-causing bacteria becomes more difficult when antibiotics stop working. People with pre-existing conditions in particular can carry resistant germs and suffer from repeated infections for years, according to a study by the University and University Hospital of Basel. Pneumonia, urinary tract infections, sepsis: diseases like these can become fatal without antibiotics.

’Genomic time machine’ reveals secrets of our DNA
Researchers reveal a novel method to uncover bits of our genetic blueprint that come from ancient genetic parasites, offering fresh insights into human evolution and health. The human genome, an intricate tapestry of genetic information for life, has proven to be a treasure trove of strange features.

Firing Nerve Fibers in the Brain Are Supplied with Energy on Demand
Firing Nerve Fibers in the Brain Are Supplied with Energy on Demand
To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical signals of active nerve fibers and provide them with energy on demand, as researchers have discovered. If this process, regulated by potassium, is disabled in mice, the nerve fibers are severely damaged as the animals age - resembling the defects of neurodegenerative diseases.

A virus that kills sleeping bacteria
A virus that kills sleeping bacteria
Researchers have found a virus that kills dormant bacteria. This rare discovery could help to combat germs that can't be treated with antibiotics alone. In nature, most bacteria live on the bare minimum. If they experience nutrient deficiency or stress, they shut down their metabolism in a controlled manner and go into a resting state.
