Stability lost as supernovae explode
A new model of supernovae represented as dynamical systems subject to a loss of stability sheds light on the phenomenon. This approach could be used to predict natural catastrophes before they happen.

ASME selects Maurizio Porfiri as Outstanding Young Investigator
Maurizio Porfiri, an associate professor at NYU-Poly, has been named the ASME Dynamic Systems and Controls Division Outstanding Young Investigator Award winner. His research on biomimetic robotic fish contributes to understanding animal collective behavior.
Stabilizing aircraft during takeoff and landing using math
Researchers developed a nonlinear model to study aircraft landing gear dynamics, identifying conditions for shimmy oscillations. The model provides insights into stability and design features, aiding in optimizing aircraft performance.
Removing complexity layers from the universe's creation
Physicists propose that Einstein's special relativity emerges from a combination of quantum dynamics and gravity. This theory predicts the formation of charge asymmetry between particles and anti-particles at ultra-minute fractions of seconds after the Big Bang, in agreement with recent cosmological observations.
Soft robots, in color
Researchers have created a system inspired by nature that allows soft robots to change their appearance, including camouflage against backgrounds or displaying bold colors. This technology could be used in various applications such as search and rescue operations, medical surgeries, and even signaling robots' position.
Shane Ross garners CAREER Award to advance understanding of fluid flows from blood inside the body to oil spills in bodies of water
Shane Ross' CAREER Award project aims to develop better engineering tools to understand fluid motions, with potential applications in drug delivery, cardiovascular health and pollution dispersion. The researcher plans to integrate research and education through team-based projects.
Demonstrating the importance of dynamical systems theory
Researchers used bifurcation diagrams to analyze bursting electrical activity in pancreatic beta cells, finding distinct behavioral patterns under critical parameter regions. Dynamical systems approaches are gaining importance in biology due to their ability to dissect complex systems and understand cell-signaling mechanisms.
A fitting tribute to William T. Reid by John Burns at the SIAM Annual Meeting
Professor John A. Burns received the W. T. and Idalia Reid Prize for his work in computational methods for control, design, and optimization of infinite dimensional dynamical systems. The prize is funded by an endowment from the late Mrs. Idalia Reid.

New 'green' technologies make die castings stronger
CSIRO's new dynamic gating system and ATM melt delivery system improve die casting quality by reducing porosity and increasing microstructure. These innovative technologies enable stronger castings with lower environmental impact.
SIAM Activity Group on Dynamical Systems J. D. Crawford Prize awarded
Dr. Andrew Stuart was awarded the 2007 SIAM Activity Group on Dynamical Systems J.D. Crawford Prize for his work on stochastic differential equations and their applications in physical models and Kalman-Bucy filters. The prize recognizes his outstanding contributions to the fields of stochastic ordinary and partial differential equations.
Lennart Carleson wins 2006 Abel Prize
Carleson's mathematical work on harmonic analysis and dynamical systems led to settling a conjecture that had remained unsolved for over 150 years. He also made significant contributions to the study of dynamical systems, which have applications in weather, financial markets, and biological systems.
CALIPSO monitors pulse of Soufriere Hills volcano
The CALIPSO project is the first volcano monitoring system of its type installed at an andesitic volcano. By comparing measurements with a computer model, researchers can understand what's happening beneath the surface. The goal is to measure magma reservoir size, magma inflow, and magma characteristics.
