How age and sex influence our body clocks
How age and sex influence our body clocks
Researchers have uncovered the intricacies of gene expression rhythms in humans, shedding new light on how sex and age influence our body clocks. The human body runs on a finely tuned clock synchronized to the 24-hour cycle of Earth's rotation, known as the circadian clock, which controls various physiological processes such as the sleep-wake cycle, hormone production, and metabolism.

Can Netflix keep you from sleeping soundly?
Can Netflix keep you from sleeping soundly?
Watching suspenseful TV series with cliffhangers before going to sleep has only minor effects on sleep. That's what scientists at the University of Freiburg have shown. The study reveals what happens in our brains when we sleep after a binge-watching session . Does binge-watching suspenseful TV series before going to sleep have a real impact on our sleep? This is the question that Professors Björn Rasch and Andreas Fahr from the University of Fribourg asked themselves in a project entitled 'Excessive Media Use in Times of Netflix', funded by the Swiss National Science Foundation (SNSF).

Avoiding burnout of white blood cells
Avoiding burnout of white blood cells
A research group at the University of Basel has identified a gene that drives T lymphocytes to exhaustion. This finding opens up new approaches for more effective immunotherapies. A tough battle requires endurance. This is also true for white blood cells as they tackle cancer - or more specifically for T lymphocytes or T cells, a group of white blood cells involved in the immune system's fight against cancer cells.

Artificial Intelligence Improves Efficiency of Genome Editing
Researchers at the University of Zurich have developed a new tool that uses artificial intelligence to predict the efficacy of various genome editing repair options. Unintentional errors in the correction of DNA mutations of genetic diseases can thus be reduced. Genome editing technologies offer great opportunities for treating genetic diseases.

How microbial communities shape the ocean’s ecology
A research collaboration led by ETH Zurich and MIT will receive a further USD 15 million from the New York-based Simons Foundation to investigate the behaviour of marine bacteria and microalgae. The research will focus on microbial communities that impact the ocean's carbon cycle. Without microorganisms, higher life forms would not exist.

Good and bad sleep
Good and bad sleep
When children's sleep patterns are altered by external factors, this can have consequences. This is the conclusion of a study from the University of Freiburg, which analyzed the sleep of children during the pandemic and their behavior six months later . The confinement of spring 2020 clearly affected the sleep of babies and young children.

Autonomous steering system keeps human drivers engaged
Researchers from EPFL and JTEKT Corporation have developed an automated driving system based on the concept of 'collaborative steering', which aims to increase transportation safety, efficiency, and comfort by encouraging active interaction between autonomous vehicles and their human drivers. Autonomous driving technologies have already been integrated into many mass-produced vehicles, providing human drivers with steering assistance in tasks like centering a vehicle in its lane.

Alien plant species are spreading rapidly in mountainous areas
Until now, mountain regions have been largely spared from biological invasions. But a new monitoring study shows that alien plants are spreading rapidly to higher altitudes along transport routes worldwide. Neophytes use roadsides as gateways of entry Humans, whether deliberately or unintentionally, often introduce alien plants in lowlands, then plants spread from their starting point to higher elevations, particularly along roads, which is why the researchers focused on traffic routes.
