It's the spin that makes the difference
It’s the spin that makes the difference
Biomolecules such as amino acids and sugars occur in two mirror-image forms - in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers at Empa and Forschungszentrum Jülich in Germany have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.

A sustainable fuel and chemical from the robotic lab
Artificial intelligence and automated laboratory infrastructure are massively accelerating the development of new chemical catalysts. With these tools, researchers at ETH Zurich are developing catalysts for efficiently and cost-effectively synthesising the energy source methanol from CO2. Catalysts are chemistry's hard-working little helpers.

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.

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.

Advancing forest monitoring
Advancing forest monitoring
Forests are under pressure and rapidly changing. In order to be able to react to these changes, forest monitoring is of crucial importance. The Swiss Federal Institute for Forest, Snow and Landscape Research WSL launched an initiative (SwissAIM) to improve forest monitoring. A new study sheds light on why the initiative is needed.

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.

A ’quantum leap’ at room temperature
Scientists have achieved a milestone by controlling quantum phenomena at room temperature. Image: Conceptual art of the operating device, consisting of a nanopillar-loaded drum sandwiched by two periodically segmented mirrors, allowing the laser light to strongly interact with the drum quantum mechanically at room temperature.

Vehicle tires as a source of microplastics
Vehicle tires as a source of microplastics
Tire wear of motor vehicles is responsible for a large proportion of microplastics in the environment. Researchers from Empa and the company wst21 have summarized the results of various studies in a recently published basic report in response to postulate Po 19.3559 and presented approaches for reduction.

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.

When the global climate has the hiccups
When the global climate has the hiccups
Climate changes usually happens over long periods of time, but during the last glacial period, extreme fluctuations in temperature occurred within just a few years. Researchers at the University of Basel have now been able to prove the phenomenon also occurred during the penultimate glacial period. In recent geological history, the so-called Quaternary period, there have been repeated ice ages and warm periods.

Water-worlds, the key to an exoplanet enigma
Water-worlds, the key to an exoplanet enigma
Exoplanets with a radius twice that of the Earth are rare. A team from MPIA, UNIGE and UNIBE has come up with new explanations. Why are so few exoplanets about twice the size of Earth detected? On the basis of computer simulations, a team from the Max Planck Institute for Astronomy (MPIA) and the Universities of Geneva (UNIGE) and Bern (UNIBE) has confirmed that the migration of sub-Neptunes planets - water-worlds - could explain this absence.

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 .

Innovative coating prevents limescale formation
Innovative coating prevents limescale formation
Wherever hot water flows, limescale is never far away. In households, this is a nuisance; in thermal power stations, it's an expensive problem. Now researchers at ETH Zurich have found an answer. Hot water tanks, washing machines, kettles: limescale forms in every domestic appliance that comes into contact with (hot) water - especially in areas where the water is hard, meaning high in calcium.

When nanoplastics are not what they seem
When nanoplastics are not what they seem
Textiles made of synthetic fibers release microand nanoplastics during washing. researchers have now been able to show: Some of the supposed nanoplastics do not actually consist of plastic particles, but of water-insoluble oligomers. The effects they have on humans and the environment are not yet well-understood.

Erosion promotes species diversity
Erosion promotes species diversity
Madagascar is home to over 11,000 plant species, 80 percent of which are found nowhere else on Earth. A recent study by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL and ETH Zurich has put forward a new hypothesis for the underlying cause of Madagascar's rich plant biodiversity, which has been regarded as an unsolved mystery of natural history.

Why olivine and diamonds are best friends
Why olivine and diamonds are best friends
Hardly any gemstone is more difficult to find than diamonds. Geologists from ETH Zurich and the University of Melbourne have now established a link between their occurrence and the mineral olivine. This could make the search for diamonds easier in the future. In brief The abundance of magnesium and iron in the mineral olivine provides information on whether or not diamonds could be present in a kimberlite rock sample.

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.

GPT-3 transforms chemical research
GPT-3 transforms chemical research
Scientists at EPFL demonstrate how GPT-3 can transform chemical analysis, making it faster and more user-friendly. Artificial intelligence is growing into a pivotal tool in chemical research, offering novel methods to tackle complex challenges that traditional approaches struggle with. One subtype of artificial intelligence that has seen increasing use in chemistry is machine learning, which uses algorithms and statistical models to make decisions based on data and perform tasks that it has not been explicitly programmed for.

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.
