New approach in the synthesis of complex natural substances
New approach in the synthesis of complex natural substances
They are found as fragrances in cosmetics or as flavorings in food, and form the basis of new medications: Terpenes are natural substances that occur in plants, insects and sea sponges. They are difficult to produce synthetically. However, chemists at the University of Basel are now introducing a new method of synthesis.

Blood diagnostics modelled on leeches
Blood diagnostics modelled on leeches
Researchers at ETH Zurich have developed a safe and inexpensive device for reliable blood measurements. It works using a suction cup and could also be employed to diagnose the tropical disease malaria - even by non-medical personnel. Many people are afraid of needles, and having a doctor take a blood sample from their arm makes them uncomfortable.

A new anticoagulant with no risk of bleeding
A new anticoagulant with no risk of bleeding
A team from the University of Geneva, in collaboration with the University of Sydney, has developed a new type of anticoagulant whose action can be rapidly stopped. Anticoagulant treatments are crucial for managing many conditions, such as heart disease, stroke and venous thrombosis. Current options, however, carry an inherent risk of serious bleeding due to trauma or unforeseen events.

How the plant world shapes the climate cycle
How the plant world shapes the climate cycle
In order to understand the Earth's resilience, researchers at ETH Zurich are modelling climate changes from times long past. And they show: Plants are not simply victims of circumstances, but have helped to shape climate conditions on Earth. Over the course of hundreds of millions of years, Earth has lived through a series of climatic shifts, shaping the planet as we know it today.

Trotting robots reveal emergence of animal gait transitions
Trotting robots reveal emergence of animal gait transitions
A four-legged robot trained with machine learning by researchers has learned to avoid falls by spontaneously switching between walking, trotting, and pronking - a milestone for roboticists as well as biologists interested in animal locomotion. With the help of a form of machine learning called deep reinforcement learning (DRL), the EPFL robot notably learned to transition from trotting to pronking - a leaping, arch-backed gait used by animals like springbok and gazelles - to navigate a challenging terrain with gaps ranging from 14-30cm.

With a gambling ban against addiction and over-indebtedness
With a gambling ban against addiction and over-indebtedness
Since 2000, Switzerland has had a statutory gambling ban. This can be applied for voluntarily by those affected or ordered by casinos and lotteries in order to prevent over-indebtedness. A study by the Lucerne University of Applied Sciences and Arts has investigated whether this gambling ban is an effective measure to protect players and how it affects the gambling behavior and quality of life of those affected.

Genome editing: huge potential in Africa
Genome editing: huge potential in Africa
Before the advent of CRISPR-Cas9 in 2012, precise genome modification was a complex process requiring heavy investment. Simple and fast, this revolutionary technology enables scientists to cut the DNA of plants, animals and humans at precise points, opening up previously unimaginable opportunities, such as the creation of disease-resistant plants or the treatment of diseases of genetic origin .

Curiosity promotes biodiversity
Curiosity promotes biodiversity
Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers from the Universities of Bern and Basel in the journal Science. This trait influences the cichlids' ability to adapt to new habitats. Exploratory behavior is one of the fundamental personality traits of animals - and these traits influence their probability of survival, among other things.

Scientists capture X-rays from upward positive lightning
Scientists capture X-rays from upward positive lightning
Researchers have for the first time recorded X-rays being produced at the beginning of upward positive lightning flashes; an observation that gives important insight into the origins of this rare - and particularly dangerous - form of lightning. Globally, lightning is responsible for over 4,000 fatalities and billions of dollars in damage every year; Switzerland itself weathers up to 150,000 strikes annually.

When the digestive system influences a child's sleep
When the digestive system influences a child’s sleep
Sleep cycles and neurological development in children are closely linked to interactions between the brain and the gut. Two researchers from the University of Fribourg, in collaboration with colleagues from ETH Zurich and Lucerne Children's Hospital, have just been awarded a 2.4 million SNSF grant to better understand these mechanisms, which are fundamental to the health of toddlers .

Mini-colons revolutionize colorectal cancer research
In a breakthrough for cancer research, scientists at EPFL have created lab-grown mini-colons that can accurately mimic the development of colorectal tumors, offering a powerful new tool for studying and testing treatments for the disease. As our battle against cancer rages on, the quest for more sophisticated and realistic models to study tumor development has never been more critical.

How to clean up New Delhi’s smoggy air
An international study led by atmospheric researchers at PSI shows for the first time what portions of particulates in the air over northern India are especially harmful to health. According to the World Health Organisation, as many as 1.3 million deaths per year on the subcontinent can be attributed to polluted air.

AI designs new drugs based on protein structures
A new computer process developed by chemists at ETH Zurich makes it possible to generate active pharmaceutical ingredients quickly and easily based on a protein's three-dimensional surface. The new process could revolutionise drug research. "It's a real breakthrough for drug discovery," says Gisbert Schneider, Professor at ETH Zurich's Department of Chemistry and Applied Biosciences.

Eruption of mega-magnetic star lights up nearby galaxy
Thanks to ESA satellites, an international team including researchers has detected a giant eruption coming from a magnetar, an extremely magnetic neutron star. While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays - high-energy photons - coming from the nearby galaxy M82.

Bacteria for climate-neutral chemicals of the future
Bacteria for climate-neutral chemicals of the future
Researchers at ETH Zurich have engineered bacteria in the laboratory to efficiently use methanol. The metabolism of these bacteria can now be tapped into to produce valuable products currently made by the chemical industry from fossil fuels. To produce various chemicals such as plastics, dyes or artificial flavours, the chemical industry currently relies heavily on fossil resources such as crude oil.

Climate change in the early Middle Ages triggered by volcanic eruptions in Iceland
Climate change in the early Middle Ages triggered by volcanic eruptions in Iceland
Icebergs on the Bosporus and a frozen Black Sea: an international study by the University of Bern with the participation of the Austrian Academy of Sciences shows how volcanic eruptions on Iceland influenced the European climate in the early Middle Ages and led to severe winter cooling anomalies. It was one of the coldest winters the region has ever experienced: In 763, large parts of the Black Sea froze over and icebergs were sighted on the Boporus.

Spatial-temporal detection of apoptotic cell death in live-cell imaging
Spatial-temporal detection of apoptotic cell death in live-cell imaging
Apoptotic cell death is a crucial mechanism that contributes to tissue homeostasis and prevents the onset of several diseases. However, this phenomenon is challenging to identify within microscopy movies that can encompass thousands of cells. Led by Santiago Gonzalez, the recent study carried at the Institute for Research in Biomedicine (IRB) in Bellinzona, affiliated with USI, introduces ADeS, an innovative approach based on artificial intelligence for the automatic detection of apoptotic cells in microscopy movies.

Understanding muscle regeneration with zebrafish
Understanding muscle regeneration with zebrafish
In humans, muscles can only regenerate from small injuries, such as those resulting from sporting activities. After an accident or combat injury, large wounds often cause deep damage to muscles, which fail to regenerate and scar. Some animals, on the other hand, replace injured body parts perfectly.
