Alarming long-term effects of insecticides weaken ant colonies
Alarming long-term effects of insecticides weaken ant colonies
This week, scientists of the Institute of Bee Health of the University of Bern have published an article in the peer-reviewed journal Communications Biology, which shows how even low doses of neonicotinoid insecticides, as they may realistically occur in contaminated soils, adversely affect the development of black garden ants (Lasius niger).

Making geothermal energy safer through simulation
Making geothermal energy safer through simulation
Researchers from the Swiss Seismological Service SED and ETH Zurich are working with the Swiss National Supercomputing Centre CSCS to develop a way of utilising geothermal energy safely with the help of supercomputers. According to Switzerland's Energy Strategy 2050, the plan is for deep geothermal energy to contribute to the expansion of renewable energies in the country.

From age 8 we spontaneously link vocal to facial emotion
From age 8 we spontaneously link vocal to facial emotion
Scientists have tracked the eye movements of children to show how they make the link - spontaneously and without instructions - between vocal emotion (happiness or anger) followed by a natural or virtual face. Do children have to wait until age 8 to recognise - spontaneously and without instructions - the same emotion of happiness or anger depending on whether it is expressed by a voice or on a face? A team of scientists from the University of Geneva and the Swiss Centre for Affective Sciences (CISA) has provided an initial response to this question.

Climate change is altering terrestrial water availability
Climate change is altering terrestrial water availability
The amount and location of available terrestrial water is changing worldwide. An international research team led by ETH Zurich has now proved for the first time that human-induced climate change is responsible for the changes observed in available terrestrial water. Water is the lifeblood of ecosystems and one of the most important natural resources for human beings.

Ethnolinguistic diversity slows down urban growth
Ethnolinguistic diversity slows down urban growth
Where various ethnic groups live together, cities grow at a slower rate. That is the conclusion reached by a researcher from the University of Basel and his colleagues based on worldwide data that shows how the diversity of language groups in 1975 has influenced urban growth 40 years later. The scientists have reported their findings in the journal Proceedings of the National Academy of Sciences.

A new theory for Semiconductors made of nanocrystals
A new theory for Semiconductors made of nanocrystals
Researchers have provided the first theoretical explanation for how electrical current is conducted in semiconductors made of nanocrystals. In the future, this could lead to the development of new sensors, lasers or LEDs for TV screens. A few years ago, we were introduced to TV screens featuring QLED technology that produces brilliant colours.

EPFL lab develops method for designing lower-power circuits
EPFL lab develops method for designing lower-power circuits
An EPFL lab, has come up with a new type of logic diagram and related optimization methods, that can be used to design computer chips with a nearly 20% gain in energy efficiency, speed or size. The lab has just entered into a license agreement with Synopsys, a global leader in electronic design automation and chip fabrication software.

Warning on affluence
Lorenz Keysser believes that in order to overcome ecological crises, we must recognise affluence as a main driver and fundamentally reconsider our economy and lifestyle. A new mobile phone here, a new dress there, heading on holiday by SUV or further afield by plane, and - for those who can afford it - a big house.

Dolphins Learn in Similar Ways to Great Apes
Dolphins Learn in Similar Ways to Great Apes
Dolphins learn new foraging techniques not just from their mothers, but also from their peers, a study by the University of Zurich has found. More than 1,000 bottlenose dolphins in Shark Bay, Western Australia were observed over 10 years and found to have cultural behavior that is similar to great apes.

Towards a Swiss Food Strategy for 2050
Towards a Swiss Food Strategy for 2050
NRP 69 recommends that the government develop a Swiss Food Strategy for 2050. This strategy should enable the entire population to eat healthy food sourced from a sustainable production and distribution system. Is it possible to follow a healthy diet that includes more vegetables, fruit and nuts while still reducing the environmental impact that consumption has both in Switzerland and abroad? Funded by the Swiss National Science Foundation (SNSF), the National Research Programme "Healthy Eating and Sustainable Food Production" (NRP 69) believes it is.

X-ray vision and eavesdropping ensure quality
X-ray vision and eavesdropping ensure quality
With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams.

Wavy surfaces for better light control
Wavy surfaces for better light control
Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometre precision. In the future this method could be used, for instance, to make optical components for data transmission on the internet even more efficient and compact. The importance of light-based technologies for our society was demonstrated once more in recent weeks.

Swiss federal government officially launches the SwissCovid app
Swiss federal government officially launches the SwissCovid app
SwissCovid - a tracing app developed in part by EPFL - is being made available today to the general public, one month after the pilot tests began. The app will be a useful tool in stemming the spread of the disease as the number of cases in Switzerland is back on the rise. The World Health Organization was clear in its warning: the COVID-19 pandemic is not over, and in some places it's just as strong as ever.

Genetic Malfunction of Brain Astrocytes Triggers Migraine
Genetic Malfunction of Brain Astrocytes Triggers Migraine
Neuroscientists of the University of Zurich shed a new light on the mechanisms responsible for familial migraine: They show that a genetic dysfunction in specific brain cells of the cingulate cortex area strongly influences head pain occurrence. Migraine is one of the most disabling disorders, affecting one in seven people and causing a tremendous social and economic burden.

Unravelling complex relationships between humans and nature
Unravelling complex relationships between humans and nature
Environmental problems are generally complex, and the ecological processes and actors involved are often closely interlinked. Social-ecological networks make it possible to untangle such complex relationships. In these networks, social and ecological components and the interactions between them are represented as nodes and links.

Blocking sugar metabolism slows lung tumour growth
Treatments that block two sugar-transporting proteins could help slow the growth of lung tumours, new research from EPFL suggests. Blocking a pair of sugar-transporting proteins may be a useful treatment approach for lung cancer, suggests a new study in mice and human cells published today in eLife .

Deep Drone Acrobatics
A navigation algorithm developed at the University of Zurich enables drones to learn challenging acrobatic maneuvers. Autonomous quadcopters can be trained using simulations to increase their speed, agility and efficiency, which benefits conventional search and rescue operations. Since the dawn of flight, pilots have used acrobatic maneuvers to test the limits of their airplanes.

Growing polymers with different lengths
ETH researchers have developed a new method for producing polymers with different lengths. This paves the way for new classes of polymer materials to be used in previously inconceivable applications. It is hard to imagine everyday life without materials made of synthetic polymers. Clothes, car parts, computers or packaging - they all consist of polymer materials.
