The reliability of data storage and writing speed in advanced magnetic devices depend on drastic, complex changes in microscopic magnetic domain structures. However, it is extremely challenging to quantify these changes, limiting our understanding of magnetic phenomena. To tackle this, researchers developed, using machine learning and topology, an analysis method that quantifies the complexity of the magnetic domain structures, revealing hidden features of magnetization reversal that are hardly seen by human eyes.

Reducing redundant information to find simplifying patterns in data sets and complex networks is a scientific challenge in many knowledge fields. Moreover, detecting the dimensionality of the data is still a hard-to-solve problem. A new article presents a method to infer the dimensionality of complex networks through the application of hyperbolic geometrics, which capture the complexity of relational structures of the real world in many diverse domains.

America was unprepared for the magnitude of the pandemic, which overwhelmed many counties and filled some hospitals to capacity. A new study suggests there may have been a mathematical method, of sorts, to the madness of those early COVID days.

Music and arts classes are often first on the chopping block when schools face tight budgets and pressure to achieve high scores on standardized tests. But it's precisely those classes that can increase student interest in school and even benefit their math achievement, according to a new study.

Policy makers assume that adding more detail to mathematical models will produce more accurate predictions, but that's not always the case, a new study shows.

Predicting the rupture of aneurysms is crucial for medical prevention and treatment. As aspect ratio and size ratio increase and an aneurysm expands, the stress applied against the aneurysm walls and the time blood spends within it increase. This leads the probability of rupture to rise. Researchers develop a patient-specific mathematical model to examine what aneurysm parameters influence rupture risk prior to surgery. Computed tomography scans are fed into the model, which reconstructs the geometry and blood flow of the aneurysm. It then uses equations to describe the fluid flow, generating information about the blood vessel walls and blood flow patterns.

Two researchers have published a study that asked students if they see themselves as a math or science person, then followed up with them several times in following years. Results showed those who said yes in ninth grade were much likelier to major in STEM subjects and work in related fields after college. The results show the importance of helping students have positive math and science experiences early and could be a way to help address equity gaps in STEM.

Forensic dramas on TV make it seem easy to determine when fingerprints were left at the scene of a crime. In reality, the oils in fingerprints degrade over time, and it's difficult to figure out their age. Now, researchers have discovered molecular markers for changes to these oils over a seven-day time period -- information that could be used to estimate fingerprints' ages more accurately.

Researchers have developed a new mathematical technique to begin to understand how a cell's nucleus is organized. They hope this understanding will expose vulnerabilities that can be targeted to reprogram a cell to stop cancer or other diseases.
