Pesticide Exposure Associated with Headaches in Children
Pesticide Exposure Associated with Headaches in Children
Children living in agricultural areas are likely to be exposed to a variety of pesticides during their daily lives, which may impair their neurodevelopment. The most vulnerable populations are families and farmworkers in lowand middle-income countries. In a study published in Environment International by Swiss TPH and partners at the University of Cape Town, researchers found that children in South Africa who engage in pesticide-related farm activities often have more headaches and possibly lower cognitive performance.

Listening or lip-reading? It's down to brainwaves
Listening or lip-reading? It’s down to brainwaves
Researchers supported by the Swiss National Science Foundation have discovered that neural oscillations determine whether the brain chooses eyes or ears to interpret speech. To decipher what a person is telling us, we rely on what we hear as well as on what we see by observing lip movements and facial expressions.

Shortcuts lead to greater pesticide contamination
Shortcuts lead to greater pesticide contamination
In agricultural areas, large volumes of water from fields, roads and paths drain directly into streams via manholes and other forms of artificial drainage. These shortcuts also transport pesticides into surface waters - and, according to a new study, in significantly larger quantities than was previously assumed.

A malformation illustrates the incredible plasticity of the brain
People born without a corpus callosum do not have a bridge between the two cerebral hemispheres. Neuroscientists from the University of Geneva have shown how the brain manages to adapt. One in 4,000 people is born without a corpus callosum, a brain structure consisting of neural fibres that are used to transfer information from one hemisphere to the other.

The influence of wind on underwater landslides in Lake Biel
The influence of wind on underwater landslides in Lake Biel
When the wind on Lake Biel blows from the south-west and it rains heavily, large quantities of sediment are washed out of the River Aare into the lake. Since the south-west wind also influences the circulation in the lake, the wind direction determines to a large extent where the sediment is deposited in the lake, namely along the eastern shore towards Biel - an important finding for identifying areas at risk of landslides.

Paracetamol poisonings up
In 2003, the painkiller paracetamol became available in Switzerland in tablets with a higher dose of the active ingredient. This correlates with an increase in cases of paracetamol poisoning in the country, as a data analysis by ETH researchers shows. Paracetamol is a popular source of pain relief. In Switzerland, it is available over the counter in 500 milligram tablets, but also in double the dose, in 1,000 milligram (1 gram) tablets when prescribed by a physician.
