Making history with 42 digits: Scientists at Paderborn University and KU Leuven have unlocked a decades-old mystery of mathematics with the so-called ninth Dedekind number. Experts worldwide have been searching for the value since 1991. The Paderborn scientists arrived at the exact sequence of numbers with the help of the Noctua supercomputer located there.

Researchers at the Universidad Carlos III de Madrid (UC3M) and the Universidad Complutense de Madrid (UCM) have discovered a phase shift between chaotic states that can appear in herds of animals and, in particular, in swarms of insects. This advance may help to better understand their behaviour or be applied to the study of the movement of cells or tumours.

A study inspired by the Japanese paper-cutting art provides a blueprint for designing shape-shifting materials and devices. Kirigami takes pop-up books to a whole new level. The Japanese paper craft involves cutting patterns in paper to transform a two-dimensional sheet into an intricate, three-dimensional structure when partially folded.

In theory, quantum computers vastly outperform classical computers in terms of computing speed. For them to do so in practice, it is necessary to design more and novel high-speed algorithms, says ETH supercomputing specialist Torsten Hoefler. Quantum computers promise to be capable of solving some computational problems much faster than classical computers.

It's more important than ever for artificial intelligence to estimate how accurately it is explaining data. Despite their enormous size and power, today's artificial intelligence systems routinely fail to distinguish between hallucination and reality. Autonomous driving systems can fail to perceive pedestrians and emergency vehicles right in front of them, with fatal consequences.

Scientists have known that when a mouse embryo is developing, the cells that will become its spine and muscles switch specific genes on and off repeatedly, in a synchronous fashion. However, there are deep mysteries about how these cells synchronize. FMI researchers have now developed a mathematical model that not only better explains how spontaneous synchronization arises in a developing mouse embryo, but may also offer some fundamental clues about how other biological systems sync up.

California blackworms tangle themselves up by the thousands, then separate in a split second. Their trick may inspire the design of self-detangling materials and fibers. As anyone who has ever unwound a string of holiday lights or detangled a lock of snarled hair knows, undoing a knot of fibers takes a lot longer than tangling it up in the first place.

Hendrik Weber and Raimar Wulkenhaar from the -Mathematics Münster- Cluster of Excellence work together on mathematical solutions Excellent research is not possible without interdisciplinary working. But, even within one discipline, collaborations crossing the barriers between research areas can lead to new approaches and findings.

April 13, 2023 The story of how a Waterloo computer science professor helped find the elusive einstein tile By Joe Petrik Cheriton School of Computer Science A nearly 60-year-old mathematical problem has finally been solved. The story began last fall when David Smith, a retired print technician from Yorkshire, England, came upon a shape with a tantalizing property.

It doesn't have to be a hurricane or a tsunami - even a simple running water tap induces a shock wave upon impact with the sink. Now, with the help of CSCS's supercomputer "Piz Daint", mathematician Siddhartha Mishra of ETH Zürich is working to overcome current barriers to simulating and comprehending highly turbulent flows.

For the first time, a mathematical model for reaching sexual climax has been successfully calculated. 'Don't overthink it' finds the research, which could be used to improve treatment of some conditions. The mathematical model focuses on male arousal, with a formula for female climax to follow. University of Sussex mathematicians have developed the first ever mathematical model of how to reach sexual climax, as revealed in a new paper.

Novel research from the Royal Veterinary College (RVC) examining the human walk has been able to predict leg and foot proportions using collisional geometry. The findings suggest why modern humans have a knee halfway down their legs, short heel and toes, a stiff, longer midfoot, and why a comfortable step is two to three feet long.

EPFL mathematicians, in collaboration with Purdue University, have settled a 30-year-old question about spheres and 4-dimensional spaces. The results bring new light to the "Euler Class," one of the most powerful tools to understand complicated spaces. For mathematicians, "Euler Class" is one of the most powerful tools for understanding complicated spaces by cutting them into simpler pieces.

NWO has awarded funding of 760,000 euros for research into the mathematical modelling of thin polymer films. In the PRONTO project, mathematicians at Utrecht University and computational chemists at the University of Amsterdam will work together with non-academic partners to develop a new generation of models for materials science.

A new programme aims to extract useful information from huge, complex datasets. Bath mathematicians will be building models to identify big dataset anomalies. A new UK-wide research programme that aims to extract useful information from huge, complex datasets has been launched. As part of the programme, mathematicians from the University of Bath will be developing tools to identify dataset anomalies that point to serious problems that might otherwise go undetected.

Mathematical model conceptualizes the relationship between kidneys and muscles Having levels of potassium that are too high or too low can be fatal. A new mathematical model sheds light on the often mysterious ways the body regulates this important electrolyte. Potassium, a common mineral abundant in food like bananas and leafy greens, is essential to normal cellular function.

A new measure can help scientists decide which estimation method to use when modeling a particular data problem. Close If a scientist wanted to forecast ocean currents to understand how pollution travels after an oil spill, she could use a common approach that looks at currents traveling between 10 and 200 kilometers.

A new mathematical model that predicts how a tossed stone will skim across the surface of water has potential applications in aircraft design, finds a study involving UCL researchers. The mathematical model, published in Proceedings of the Royal Society A , factors together the possible shapes and weights of a stone, the different speeds and directions of a throw and the momentum and pressure of the water as the stone impacts.

A team led by researchers from Universidad Carlos III de Madrid (UC3M) and Universidad Politécnica de Madrid (UPM) has developed a new mathematical model to study changes in ecological interactions between microbe populations. One of the conclusions they have found is that there is a trend towards mutualism, that is, towards a relationship in which species benefit each other.

A new research project led by Luca Gambardella, professor at the Dalle Molle Institute for Artificial Intelligence IDSIA (USI-SUPSI) and Pro-Rector for Innovation and Corporate Relations, has been approved by the  Swiss National Science Foundation (SNSF) . The study entitled 'Computational methods for integrality gaps analysis' approaches the optimisation of algorithms to deal with complex problems from an innovative and original perspective.
