Research efforts to reduce pesticide contamination
Research efforts to reduce pesticide contamination
With the latest analytical methods, potentially toxic substances can be detected even at very low concentrations. However, the aim of research is not merely to document such contamination but also to understand how it occurs in streams and groundwater, and to propose mitigation measures. In agricultural areas, large volumes of water from fields, roads and paths enter streams via manholes or other artificial drainage systems.

Bilingualism as a natural therapy for autistic children
Bilingualism as a natural therapy for autistic children
An international team led by UNIGE demonstrates that the characteristics of bilingualism allow autistic children to compensate for certain fundamental deficits. Affecting more than one in a hundred children, autism spectrum disorder is one of the most common neurodevelopmental disorders. It has a particular impact on social interaction, including difficulties in understanding other people's perspectives, beliefs, desires and emotions, known as 'theory of mind'.

Filter membrane renders viruses harmless
Researchers at ETH Zurich are developing a new filter membrane that is highly efficient at filtering and inactivating a wide variety of air-borne and water-borne viruses. Made from ecologically sound materials, the membrane has an appropriately good environmental footprint. Viruses can spread not only via droplets or aerosols like the new coronavirus, but in water, too.

Plastic waste in the sea mainly drifts near the coast
A study conducted at the Oeschger Centre for Climate Change Research at the University of Bern provides new insights into the pollution of the world's oceans with plastic waste. The modelling shows that most of the plastic does not end up in the open ocean, but beaches or drifts in the water near the coast.

Cutting-edge modelling methods from USI help unlock the secrets of porous material
Cutting-edge modelling methods from USI help unlock the secrets of porous material
Most materials have a seemingly smooth surface, but under high magnification, they reveal to be full of tiny holes or pores. Zeolites, in particular, have pores in different sizes that allow them to be used in a range of different applications like catalysis, the branch of chemistry that studies how to accelerate chemical reactions, a fundamental pillar for the chemical industry. However, many fundamental questions remain about what actually happens inside the pores of a zeolite and, more precisely, how water influences the overall behaviour of the system.

Replicating patients’ tumours to test different treatments
UNIGE Researchers have developed in vitro tumour models that incorporate components of the tumour and elements of the patient's immune system to test the effectiveness of treatments. Every tumour is different, every patient is different. So how do we know which treatment will work best for the patient and eradicate the cancer?

Luring bacteria into a trap
Luring bacteria into a trap
Researchers at ETH Zurich and the University of Basel have developed a vaccine that protects animals from Salmonella . These bacteria often escape the effects of vaccination by genetically modifying their protective coat. The researchers have succeeded in manipulating this process to lure the bacteria into an evolutionary trap.

Mass scale manipulation of Twitter Trends discovered
New EPFL research has found that almost half of local Twitter trending topics in Turkey are fake, a scale of manipulation previously unheard of. It also proves for the first time that many trends are created solely by bots due to a vulnerability in Twitter's Trends algorithm. Social media has become ubiquitous in our modern, daily lives.

Researchers identify how to prevent cancer metastases
Metastases can develop in the body even years after apparently successful cancer treatment. They originate from cancer cells that migrated from the original tumor to other organs, and which can lie there inactive for a considerable time. Researchers have now discovered how these "sleeping cells" are kept dormant and how they wake up and form fatal metastases.

Microbial biodiversity has a new dimension
Microbial biodiversity has a new dimension
Microbes self-organise to grow into fascinating and complex patterns. The diversity of these patterns depends on a previously unknown factor, as researchers at Eawag have discovered. This might re-define how we view the concept of microbial biodiversity. The microbes in our gut help us digest food, and help us to defend against pathogens.
