New ways to improve the science of ‘trade-offs’

Researchers working on complicated problems in agriculture, ecology and medicine have developed a mathematical model to enable faster solutions. more...

New mathematical solutions to an old problem in astronomy

The Bernese theoretical astrophysicist Kevin Heng has achieved a rare feat: On paper, he has derived novel solutions to an old mathematical problem needed to calculate light reflections from planets and moons. Now, data can be interpreted in a simple way to understand planetary atmospheres, for example. The new formulae will likely be incorporated into future textbooks. more...

A universal equation for the shape of an egg

Researchers have discovered a universal mathematical formula that can describe any bird's egg existing in nature -- a significant step in understanding not only the egg shape itself, but also how and why it evolved, thus making widespread biological and technological applications possible. more...

A new model for group decision-making shows how 'followers' can influence the outcome

From small committees to national elections, group decision-making can be complicated -- and it may not always settle on the best choice. That's partly because some members of the group do research on their own, and others take their cues from the people around them. A new mathematical framework predicts that decision-making groups have a critical threshold of people who get their information from others. Below that threshold, the group chooses the high-quality outcome. Above it, the group can end up choosing the better or worse option. more...

Robot mimics the powerful punch of the mantis shrimp

Mantis shrimp pack the strongest punch of any creature in the animal kingdom. How mantis shrimp produce these deadly, ultra-fast movements has long fascinated biologists. Now, an interdisciplinary team of roboticists, engineers and biologists have modeled the mechanics of the mantis shrimp's punch and built a robot that mimics the movement. The research sheds light on the biology of these pugnacious crustaceans and paves the way for small but mighty robotic devices. more...

Mathematicians build an algorithm to ‘do the twist’

Mathematicians have developed an algorithm to decipher the rotational dynamics of twisting particles in large complex systems from the X-ray scattering patterns observed in X-ray photon correlation spectroscopy experiments. more...

From mathematics to medicine: Applying complex mathematics to analyze fMRI data

Mathematical research is aiding in the analysis of fMRI data. fMRI is the preeminent class of signals collected from the brain in vivo and is irreplaceable in the study of brain dysfunction in many medical fields, including psychiatry, neurology and pediatrics. more...
