An ironclad future
An ironclad future
Solar energy plays an important role in the fight against climate change as a substitute for fossil fuels. Dye-sensitized solar cells promise to be a low-cost supplement to the photovoltaic systems we know today. Their key feature is the dye sensitizers attached to their surface. Researchers at the University of Basel continue to improve the performance with sensitizers using iron - a commonly available and environmentally friendly metal.

Basel's valuable virus collection for worldwide research
Basel’s valuable virus collection for worldwide research
Phages are viruses that infect bacteria. They are an important part of many of the Earth's ecosystems and can also play a role in the fight against antibiotic resistant pathogens. A research team from the University of Basel's Biozentrum has now compiled a significant phage collection. It is available to scientists around the world for research purposes, as a biotech tool or to explore which phages are most suitable for therapy.

A histone modification essential for tissue integrity
A histone modification essential for tissue integrity
Chemical modifications of histones, the small proteins around which DNA is wrapped, are known to affect gene expression. In a study conducted in C. elegans , researchers from the Gasser group show that the defining modification of the tightly packed form of DNA called heterochromatin selectively blocks the expression of genes in differentiated tissues.

A digital reconstruction of the brain's power source
A digital reconstruction of the brain's power source
The EPFL Blue Brain Project has created the first digital reconstruction of the Neuro-Glia-Vascular Architecture providing a new framework to study brain function in health and disease. The study, published in Cerebral Cortex, represents a major milestone: researchers can now reconstruct the architecture of non-neuronal entities such as blood vessels and the supporting cells called glia.

Serious security vulnerabilities in computer memories
Serious security vulnerabilities in computer memories
Researchers at ETH Zurich have discovered major vulnerabilities in DRAM memory devices, which are widely used in computers, tablets and smartphones. The vulnerabilities have now been published together with the National Cyber Security Centre, which for the first time has assigned an identification number for it.

How does a wing grow? A journey on the path of proteins
How does a wing grow? A journey on the path of proteins
To form an organ, cells must communicate properly and develop their number, shape and size down to the smallest detail. A research team at the University of Basel investigates wing growth in the fruit fly and now has refuted a long-standing dogma. Contrary to what was previously assumed, the team showed that the dispersal of a signalling molecule called Dpp is not responsible for the entire wing shape and size.

Discovering exoplanets using artificial intelligence
Discovering exoplanets using artificial intelligence
By implementing artificial intelligence techniques similar to those used in autonomous cars, a team from the UNIGE and the UniBE, in partnership with the company Disaitek, has discovered a new method for detecting exoplanets. The majority of exoplanets discovered to date have been discovered using the transit method.

Teaching fungi how to write
Teaching fungi how to write
Spalted wood is a highly sought-after material in the high-end furniture industry. In a newly developed process, scientists have succeeded at controlling the spread of fungi in native wood types to create elaborate marblewood pictures - and even taught the fungi to write some words. Fine black lines spread elegantly across the clock face made from pale, fine-grained timber of ash, beech and maple.

When algorithms get creative
Uncovering the mechanisms of learning via synaptic plasticity is a critical step towards understanding how our brains function and building truly intelligent, adaptive machines. Researchers from the University of Bern propose a new approach in which algorithms mimic biological evolution and learn efficiently through creative evolution.

New imaging method gives live glimpse into how cells work
New imaging method gives live glimpse into how cells work
By combining two microscopy methods, researchers are able to see what is happening inside a cell and on its membrane simultaneously, giving unprecedented insight into the cellular processes that occur during infection, for example. Cells are the fundamental component of living organisms and play host to a number of complex biological phenomena.

Crushed resistance
Crushed resistance
Geophysicists can use a new model to explain the behaviour of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains on its underside are shrunk in size. The Earth's surface consists of a few large plates and numerous smaller ones that are continuously moving either away from or towards each other at an extremely slow pace.

Brain connections have their own tempo
Brain connections have their own tempo
Scientists from the University of Geneva show that during development, the different populations of neurons needed for connections between brain areas share similar genetic programs, but which unfold at different speeds. The cerebral cortex, located at the surface of the brain, handles the cognitive, language, and complex functions that allow us to represent the world or project ourselves into the future.

How electric cars help to reduce electricity imports
How electric cars help to reduce electricity imports
Swiss electricity generation has a very low carbon footprint. However, this is often not the case for imports. Researchers from the National Centre of Competence in Research (NCCR) Automation, led by Empa researcher Loris di Natale, investigated how electric cars could help reduce the need for energy imports from fossil fuels.

Finding inspiration in starfish larva
Finding inspiration in starfish larva
Researchers at ETH Zurich have developed a tiny robot that mimics the movement of a starfish larva. It is driven by sound waves and equipped with tiny hairs that direct the fluid around it, just like its natural model. In the future, such microswimmers could deliver drugs to diseased cells with pinpoint accuracy.

Transport pricing in practice
In the largest worldwide pricing experiment to date, researchers from the University of Basel, ETH Zurich and ZHAW have demonstrated that road users change their behavior when they must pay for the social and environmental effects of their transportation. The study took place in urban agglomerations in Frenchand German-speaking Switzerland.

Taking Pleasure in Exercise Reduces Stress and Improves Life Satisfaction
Taking Pleasure in Exercise Reduces Stress and Improves Life Satisfaction
Young people are less satisfied with their lives when they are stressed. Physical activity can counter this by helping to relieve stress. Researchers from the University of Basel found that intrinsic motivation plays a key role in this regard. One in four boys and one in three girls feels stressed during their schooling, a study conducted by Sucht Schweiz in 2019 found.

A Decline in Air Pollution Levels in Europe Still Fall Short of WHO Guidelines, According to New Study
For the first time, a new study by Swiss TPH used robust spatio-temporal methodology to show the reduction in air pollution across Europe from 2006-2019 and found that while exposure rates have significantly declined across Europe the past 14 years, there are large parts of the continent where the WHO guidelines on air pollution are still not met.

Mini-placentas: promising tools for studying early pregnancy and its complications
Despite its crucial role in healthy pregnancies, the placenta is one of the least understood organs in the human body. In a new study, Margherita Yayoi Turco and her colleagues compared the two main experimental models of the human placenta. The findings suggest that 3D clusters of placental cells called trophoblast organoids are best suited for investigating interactions between the mother and the fetus, hormone secretion or pathogens that infect the fetus in the womb.
