The race for the Kochen-Specker Theorem
The race for the Kochen-Specker Theorem
A world record in solving satisfiability problems was achieved at the Vienna University of Technology - it is quite abstract, but the technology behind it is extremely important for hardware and software industries . Suppose Alice, Bob, and Carla answer a question. Each of the three answers is either correct or incorrect.

Ninth Dedekind number discovered: Scientists from Paderborn and Leuven solve long-known problem in mathematics
Ninth Dedekind number discovered: Scientists from Paderborn and Leuven solve long-known problem in mathematics
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.

'Butterfly chaos effect' discovered in swarms and herds of animals
’Butterfly chaos effect’ discovered in swarms and herds of animals
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.

Turning a circle into a square is possible with this kirigami-inspired formula
Turning a circle into a square is possible with this kirigami-inspired formula
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.

'For very small problem sizes a classical computer is faster'
’For very small problem sizes a classical computer is faster’
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.

Probabilistic AI that knows how well it’s working
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.

Revealing how an embryo's cells sync up
Revealing how an embryo’s cells sync up
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.

How to untangle a worm ball: Mathematicians solve a knotty mystery
How to untangle a worm ball: Mathematicians solve a knotty mystery
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.

’Learning from one another means we arrive at findings faster’
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.

A trick of the hat
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.

Turbulent affairs: Scientists enhance the simulation of strong flow phenomena
Turbulent affairs: Scientists enhance the simulation of strong flow phenomena
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.

Want satisfaction? Do the maths
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.

New RVC research explains human foot and leg proportions
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.

Tossing coins to understand spheres
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.

New mathematical model shows how the body regulates potassium
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.

When should data scientists try a new technique?
When should data scientists try a new technique?
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.
