Breakthrough in malaria research
Breakthrough in malaria research
An international scientific consortium led by the cell biologists Volker Heussler from the University of Bern and Oliver Billker from the Umeå University in Sweden has for the first time systematically investigated the genome of the malaria parasite Plasmodium throughout its life cycle in a large-scale experiment.

Unevenly distributed plankton activity
Unevenly distributed plankton activity
An international research consortium with ETH participation demonstrates that marine plankton is more diverse in warm oceans than in polar seas, both in terms of species count and the biological activities of the plankton communities. Climate change could lead to a redistribution of plankton in the world's oceans.

Place of residence and sodas, an explosive cocktail
In a groundbreaking study published today, scientists used precision geospatial analysis techniques to show that obesity and the consumption of sugar-sweetened beverages (SSBs) are more prevalent in some parts of Geneva than others. The study, a collaboration between HUG, EPFL, UNIGE and CHUV, is the first of its kind to establish a link between place of residence, SSB consumption and high body mass index (BMI).

Observing changes in the chirality of molecules in real time
Chiral molecules - compounds that are mirror images of each other - play an important role in biological processes and in chemical synthesis. Chemists at ETH Zurich have now succeeded for the first time in using ultrafast laser pulses to observe changes in chirality during a chemical reaction in real time.

Rubber in the environment
Rubber in the environment
The tread on the tyre is worn out, new tyres are needed. Everyday life for many drivers. But where do these lost centimetres of tyre tread "disappear" to? As micro-rubbers, they mainly end up in soil and water and, to a small extent, in the air. And the amount of these particles in our environment is anything but small, as Empa researchers have now calculated.

Large storage potential in future ice-free glacier basins
Large storage potential in future ice-free glacier basins
Glaciologists at ETH Zurich and WSL assessed the global water storage and hydropower potential that could be freed up in future as glaciers melt in response to climate change. Global warming will cause substantial glacier retreat for the majority of the world's glaciers over the next few decades. This will not only spell the end for some magnificent natural monuments, but also importantly affect the water cycle.

Finest handwork
Finest handwork
In autumn 2017, the archaeological service of the Canton of Berne was amazed when two private individuals delivered a crusted lump of metal. The bronze hand of Prêles, decorated with a ribbon of gold, turned out to be the oldest bronze sculpture of a human body part in Central Europe. But where did the metals of the sensational find come from? Empa researchers were involved in the investigation.

Amoebas to replace laboratory mice
Amoebas to replace laboratory mice
The University of Geneva awards its 3R Prize to research that reduces the number of animals in experimentation through better selection of the compounds to be tested. Minimize the number of anti-infective compounds to be tested in an animal model by first selecting them on infected amoebas to retain only the most effective ones.

Opportunity makes species
Opportunity makes species
"The people who live around the Eqaluit River in the south-west of Greenland do know that there are char living in the river and its lakes", explains the evolutionary and fish biologist Carmela Dönz. "But they prefer to eat sea fish and take very little notice of the fish stocks in fresh water - which is one of the reasons why the fish appear to have little fear of people." Outside the region, the rivers and lakes along the coastline created by the retreating Greenland glaciers after the last ice age remain largely unknown.

A cheaper way to scale up atomic layer deposition
A cheaper way to scale up atomic layer deposition
Chemical engineers at EPFL have developed a new method for atomic layer deposition, a technique commonly used in high-quality microelectronics. The new method can be used in materials with larger surfaces much more cheaply than current approaches, while preserving quality and efficiency. Atomic layer deposition (ALD) involves stacking layers of atoms on top of each other like pancakes.

A fast and precise look into fibre-reinforced composites
A fast and precise look into fibre-reinforced composites
Researchers at the Paul Scherrer Institute PSI have improved a method for small angle X-ray scattering (SAXS) to such an extent that it can now be used in the development or quality control of novel fibre-reinforced composites. This means that in the future, such materials can be investigated not only with X-rays from especially powerful sources such as the Swiss Light Source SLS, but also with those from conventional X-ray tubes.

Nitrous oxide emissions set to rise in the Pacific Ocean
Nitrous oxide emissions set to rise in the Pacific Ocean
The acidification of the Pacific Ocean in northern Japan is increasing the natural production rate of N2O, an ozone-depleting greenhouse gas. That's the finding of a study carried out jointly by scientists at EPFL, Tokyo Institute of Technology and Japan Agency for Marine-Earth Science and Technology and appearing recently.

"Without Bacteria and Fungi, the Earth Would Look Like Mars"
Our soils filter drinking water and produces food. Soils only carry out these services, because they harbour thousands fungal and bacteria species which work together like the wheels in a clock mechanism. These are the conclusions reached by a study published in the renowned by researchers from Agroscope and the University of Zurich.

Aging in good health: the inequalities are widening
Aging in good health: the inequalities are widening
UNIGE researchers have been analysing the rise in healthy life expectancy in Switzerland since 1990 and measuring the differences based on an individual's level of education. Life expectancy in Switzerland has been growing steadily for decades. But have these additional years been spent in good health or, on the contrary, do they only prolong the ills of an aging population?

Magnets for the second dimension
Magnets for the second dimension
ETH scientists have developed cube-shaped magnetic building blocks that can be assembled into two-dimensional shapes and controlled by an external magnetic field. They can be used for soft robotics applications. If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it.

Using AI to predict where and when lightning will strike
Using AI to predict where and when lightning will strike
Researchers at EPFL have developed a novel way of predicting lightning strikes to the nearest 10 to 30 minutes and within a radius of 30 kilometers. The system uses a combination of standard data from weather stations and artificial intelligence. Lightning is one of the most unpredictable phenomena in nature.

"Super-grafts" that could treat diabetes
By successfully strengthening pancreatic islets before transplantation, researchers at UNIGE and HUG are hoping for a significant improvement in the success of cell transplants in patients with severe diabetes. To save patients with a severe form of type 1 diabetes (characterized by the absence of functional insulin-producing cells), pancreatic cell transplantation is sometimes the last resort.

Science Barometer Switzerland: Trust in Science and Research Remains High
The Swiss population's trust in science and research is high to very high. As the Science Barometer Switzerland 2019 study shows, people in Switzerland have a positive attitude towards science and are keen to receive information about research, with climate and energy considered the most important topics.

On the way to intelligent microrobots
On the way to intelligent microrobots
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a micromachine that can perform different actions. First nanomagnets in the components of the microrobots are magnetically programmed and then the various movements are controlled by magnetic fields. Such machines, which are only a few tens of micrometres across, could be used, for example, in the human body to perform small operations.

Synthetic phages with programmable specificity
Synthetic phages with programmable specificity
ETH researchers are using synthetic biology to reprogram bacterial viruses - commonly known as bacteriophages - to expand their natural host range. This technology paves the way for the therapeutic use of standardized, synthetic bacteriophages to treat bacterial infections. Bacteriophages ("phages" for short) are viruses that infect bacteria.
