Researchers at Universiteit van Amsterdam use fluorescence microscopy and specialized molecules to study the transition from static to dynamic friction. They find that a slip wave propagates from the edge towards the center of the contact area just before sliding occurs.
Research at large events like concerts and festivals shows that individuals exhibit 'bursty' movement patterns, stopping and resting before moving to new locations. This intermittent behavior increases the risk of spreading infectious diseases like COVID-19.
A team of researchers has discovered that gamma-ray radiation from the Sagittarius Dwarf galaxy can be explained by millisecond pulsars, ruling out dark matter annihilation as a possible explanation. The study reveals that these stellar objects are efficient accelerators of high-energy electrons and positrons.
A new study reveals sponges have a unique mechanism to clear their water channels: a sneeze-like process. Sponges release a type of mucus that is consumed by other animals, providing a food source inaccessible to most sea creatures.
Physicists from the University of Amsterdam successfully created a continuous Bose-Einstein Condensate, enabling an eternal atom laser that can produce coherent matter waves. This breakthrough solves the problem of fragile BECs and paves the way for technical applications.
A team of physicists discovered that clouds of ultralight particles around rotating black holes leave a characteristic imprint on gravitational waves. This finding suggests the existence of new particles with very low mass, predicted by several theories beyond the Standard Model of particle physics.
Researchers have found that Sowerby's beaked whales are faster, more agile hunters than expected, with shorter dives and higher frequency clicks. This unique strategy may help them avoid competition among other beaked whale species.
Scientists create S-shaped chocolate metamaterials with adjustable cracking properties and distinct sounds, allowing for a customizable eating experience. The research opens the door to designing foods that are enjoyable to eat and materials that optimize human interaction.
Physicists create cold molecular ions using a new method and detect ultracold molecules with high sensitivity. The technique uses a single trapped ion to sense tiny amounts of molecules, opening up new possibilities for precision spectroscopy and understanding ultracold collisions.
A large-scale experiment found that scientists' claims are perceived as more credible than those of spiritual gurus worldwide, with universal effect across cultures. The Einstein effect highlights the importance of scientific sources in determining information reliability.
Researchers have designed an experimental protocol to detect the dynamics of kinks and skinks, which are energy lumps and their supersymmetric partners. The study focuses on a one-dimensional lattice, but the findings may inspire more elaborate simulators in higher dimensions.
Researchers from the University of Amsterdam have found that ice can heal itself by forming a new layer of ice to cover scratches and cuts. This discovery could potentially extend breaks between skating races, but careful control of moisture in the air is still necessary.
A recent study found that older people experienced more positive and less negative emotions than younger people during the Covid-19 pandemic. This advantage was consistent across cultures and countries, with older adults better able to avoid situations that triggered negative emotions. The researchers suggest that this resilience is du...
Physicists investigate the act of measuring a quantum particle, revealing that non-linear models can reconcile quantum behavior with classical measurement outcomes. The study sheds light on the elusive crossover between quantum physics and the everyday world.
The UvA scientists have developed a fully operational standalone solar-powered mini-reactor that can synthesise drugs and other chemicals in economically relevant volumes. The system is capable of stand-alone operation in remote locations, making it suitable for applications such as Mars bases.
Researchers from UvA's Centre for Urban Mental Health propose a new conceptual framework to understand the dynamic interplay between urban factors and mental health. The framework identifies key factors influencing urban environments and their impact on mental well-being, including air pollution, noise, and social cohesion.
New research from UvA's Law Centre for Health and Life found EU policies influencing access to medicines in developing countries without always intending it. This has significant implications for the EU's own health systems, security, and stability.
