Study Finds Women Rated More Attractive.

A major international study has found that women’s faces are consistently rated as more attractive than men’s faces, even by other women. Researchers say the finding confirms the existence of a global “gender attractiveness gap.”

Scientists analysed more than 1.5 million facial attractiveness ratings collected from 52 studies across 76 countries. The research included nearly 30,000 participants who rated around 17,000 faces from different cultures and age groups.

According to the study, female faces received higher attractiveness scores across almost every category. Researchers found that women themselves gave the highest ratings to other women, while male faces generally received lower ratings.

The study also discovered that the attractiveness gap becomes smaller with age. By around 80 years old, the difference between how male and female faces are perceived almost completely disappears.

Researchers believe facial structure may partly explain the results. On average, women tend to have rounder facial features, while men often have more rectangular face shapes. Both male and female participants showed a preference for rounder faces.

Charles Darwin previously argued that sexual selection shaped physical appearance differently across species. However, scientists continue debating why humans show such strong preferences for female facial features.

The research team, led by Eugen Wassiliwizky, says the findings appear across cultures and sexual orientations, suggesting the effect may extend beyond social or cultural influences.

Experts caution that the study does not fully explain why female faces are generally rated more attractive. However, researchers believe both biology and long-term evolutionary factors may contribute to the pattern.

Swiss Scientists Develop New Gene Clock.

An international research team with Swiss participation has developed advanced “gene clocks” capable of measuring biological age and predicting lifespan in real time. The breakthrough study could transform future ageing research and health monitoring.

Scientists analysed more than 11,000 tissue samples collected from mice, rats, macaques, and humans. Researchers discovered that molecular ageing patterns inside the transcriptome remain remarkably similar across species and cell types.

The study reveals that ageing activates genes linked to inflammation, cell damage, and programmed cell death. At the same time, genes responsible for tissue repair, wound healing, and regeneration become less active as the body grows older.

Using this data, researchers created highly dynamic transcriptome clocks that can measure biological ageing more accurately. To validate the technology for humans, scientists tested the system using data from over 50,000 participants in the UK Biobank.

Experts say the new gene clocks perform similarly to modern epigenetic ageing clocks already used in scientific research. However, transcriptome clocks offer a major advantage because they respond quickly to changes happening inside cells in real time.

Researchers believe this technology could help scientists evaluate the effectiveness of anti-ageing treatments, diets, and medicines much faster than current methods. The discovery may open new opportunities in personalised healthcare and longevity research.

The study involved ETH Zurich researcher Adrian Molière and was led by Harvard Medical School scientist Vadim Gladyshev.

Hoverfly Named Switzerland’s Species of the Year 2026.

A newly identified insect species, the hoverfly Monoceromyia ndidiae, has been named Switzerland’s “Species of the Year 2026” by the Swiss Systematics Society. The announcement highlights the growing importance of citizen science in modern biological research and species discovery.

The hoverfly belongs to a family of insects known for their striking yellow-orange coloration, which often mimics wasps. This natural camouflage helps protect them from predators, even though hoverflies are completely harmless and cannot sting or bite humans.

The discovery began unexpectedly in the Dominican Republic when nature enthusiasts uploaded insect photographs to the citizen science platform iNaturalist. One particular image caught the attention of an entomologist who noticed unusual physical features that did not match any known species.

After further analysis and collaboration with international experts, researchers confirmed that the insect represented a previously unknown species. The finding was later verified and formally recognized, marking a significant contribution to biodiversity science.

Scientists from the Swiss Systematics Society emphasized that this discovery demonstrates how public participation can play a crucial role in scientific research. By sharing wildlife observations online, non-experts can help identify rare or unknown species that might otherwise go unnoticed.

The case of Monoceromyia ndidiae also highlights how global collaboration between scientists and citizen observers can accelerate discoveries in taxonomy and ecology. Researchers believe that many more undiscovered species may already exist in public photo databases waiting to be identified.

This recognition as Species of the Year 2026 celebrates both the insect itself and the global community that helped bring it to scientific attention.

Swiss-Built Smile Satellite Successfully Launches Into Space

The Smile satellite has successfully launched into space, marking a major achievement for Swiss and international space research.

A Vega-C rocket carried the satellite to an altitude of more than 700 kilometres above Earth before the spacecraft safely separated and deployed its solar panels. Scientists confirmed the mission’s successful start shortly after launch.

Researchers from the University of Applied Sciences and Arts Northwestern Switzerland played a key role in developing important components for the mission. Project leader Säm Krucker described the launch as an exciting milestone and said the satellite will now begin collecting scientific data over the next three years.

The Smile mission is a joint project between European and Chinese space agencies. Its primary goal is to better understand space weather and the interaction between solar winds and Earth’s magnetic field.

Space weather is caused by charged particles released from the Sun during solar storms. When these particles collide with Earth’s magnetic field, they can create auroras while also disrupting satellites, navigation systems, communications, and even power grids.

Swiss researchers developed and tested a cooling system for the satellite’s telescope and also contributed advanced software algorithms designed to improve image quality captured by the onboard wide-angle camera.

Swiss technology also supported the rocket itself. Beyond Gravity manufactured the rocket’s protective nose cone, which shielded the satellite during launch.

The successful mission highlights Switzerland’s growing role in global aerospace innovation and scientific space exploration.

Swiss Study Shows Wars Can Alter Groundwater and Water Systems

A new Swiss academic study has revealed that armed conflicts can significantly alter underground water systems and groundwater dynamics, reshaping how water resources behave in war-affected regions.

Research conducted at the University of Neuchâtel shows that large-scale population displacement and abandoned agricultural activity can directly influence groundwater recharge patterns.

Doctoral researcher Saeed Mhanna observed unexpected changes in an underground water system in a Syrian river basin, using satellite-based InSAR technology to study areas that are otherwise inaccessible due to ongoing conflict.

The findings suggest that when populations are forced to leave farmland during war, the cessation of irrigation allows groundwater levels to partially recover. In some locations, the soil surface even rose by up to 4 cm per year due to changes in underground pressure.

The study highlights how the invisible nature of aquifers makes wartime water assessment extremely difficult, especially when field access is restricted. Satellite data and indirect measurement techniques were therefore combined to analyze changes in water storage and recharge.

Beyond Syria, the research also examined the impact of the Kakhovka dam collapse in Ukraine in 2023. The study found that the destruction of the dam drastically disrupted the regional hydrological system along the Dnieper River.

Researchers estimate that the volume of water lost to the Black Sea after the dam’s collapse was roughly equivalent to the capacity of Lake Geneva, though with a significant margin of uncertainty.

The study demonstrates that modern satellite monitoring can play a crucial role in identifying damaged water infrastructure, tracking groundwater depletion, and detecting unexpected water recovery in conflict zones.

Experts say these insights could help governments and aid organizations prioritize emergency repairs, protect critical water infrastructure such as wells and pipelines, and improve humanitarian response in war-affected regions.

The research highlights the growing importance of space-based environmental monitoring in understanding how human conflicts reshape natural water systems over time.

‘Smile’ Space Weather Satellite Launches With Swiss Technology Onboard

The international Smile space mission is preparing for launch with important technology developed in Switzerland playing a key role in the satellite’s success.

The Smile satellite — short for Solar wind Magnetosphere Ionosphere Link Explorer — is scheduled to launch on May 19 at 05:52 Swiss time. The mission aims to improve scientific understanding of solar storms and space weather that can affect satellites, navigation systems, and even power grids on Earth.

The project is a collaboration between European and Chinese space agencies and includes contributions from Swiss researchers and technology companies.

According to André Csillaghy from the University of Applied Sciences Northwestern Switzerland (FHNW), the launch is both exciting and stressful for the engineering teams involved.

Swiss researchers developed crucial software systems and a key cooling component for the satellite’s advanced X-ray telescope. Without this technology, the telescope would not function properly in the harsh conditions of space.

The Swiss cooling system, known as the “Rocket Science radiator,” was designed and tested at FHNW in Windisch. Its purpose is to keep the telescope detectors at extremely low temperatures of around -110°C, allowing the instruments to operate accurately.

The satellite’s mission is focused on studying interactions between solar winds and Earth’s magnetic field. Charged particles from the sun travel toward Earth at extremely high speeds and interact with the planet’s protective magnetosphere.

Scientists hope Smile will provide valuable new data about space weather, which can disrupt communication systems, satellites, GPS networks, and electricity infrastructure during strong solar storms.

The spacecraft carries four major scientific instruments, including an X-ray camera, ultraviolet camera, ion spectrometer, and magnetometer. One of the mission’s biggest goals is to create the first detailed visualisation of Earth’s magnetic field using advanced X-ray imaging technology.

The Swiss engineering team has spent nearly eight years working on the mission together with partners from the Zurich University of Applied Sciences, KOEGL Space, and Space Acoustics.

Experts say the Smile mission highlights Switzerland’s growing importance in international aerospace research and advanced scientific technology development.
