Predicting risk of aneurysm rupture      (via sciencedaily.com) 

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.

Study shows how math, science identity in students affects college, career outcomes      (via sciencedaily.com) 

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.

Mixing things up: Optimizing fluid mixing with machine learning      (via sciencedaily.com) 

Fluid mixing is an important part of several industrial processes and chemical reactions. However, the process often relies on trial-and-error-based experiments instead of mathematical optimization. While turbulent mixing is effective, it cannot always be sustained and can damage the materials involved. To address this issue, researchers have now proposed an optimization approach to fluid mixing for laminar flows using machine learning, which can be extended to turbulent mixing as well.
