Creatures of influence
In the children's game "Jenga", removing the wrong block from a tower of wooden blocks can cause the entire tower to collapse. In the same way, removing certain species from an ecosystem can cause a collapse in ecological function. A common scientific question has been to identify these critical species in different ecosystems and an international research team has developed mathematical tools that can estimate which species are most influential in a food web.

Pigeon wingman rules
Pigeon wingman rules
Travelling in flocks may make individual birds feel secure but it raises the question of who decides which route the group should take. Mathematical models developed by scientists suggest that a simple set of rules can help flocks, swarms, and herds reach a collective decision about where to go. But investigating how this really works, especially with animal groups in flight, is extremely challenging.

Pinpointing when the First Dynasty of Kings ruled Egypt
For the first time, a team of scientists and archaeologists has been able to set a robust timeline for the first eight dynastic rulers of Egypt. Until now there have been no verifiable chronological records for this period or the process leading up to the formation of the Egyptian state. The chronology of Early Egypt between 4500 and 2800 BC has been reset by building mathematical models that combine new radiocarbon dates with established archaeological evidence.

Why animals compare the present with the past
Humans, like other animals, compare things. We care not only how well off we are, but whether we are better or worse off than others around us, or than we were last year. New research by scientists at the University of Bristol shows that such comparisons can give individuals an evolutionary advantage.

Model of Sun’s magnetic field
Researchers at the Universities of Leeds and Chicago have uncovered an important mechanism behind the generation of astrophysical magnetic fields such as that of the Sun. Scientists have known since the 18th Century that the Sun regularly oscillates between periods of high and low solar activity in an 11-year cycle, but have been unable to fully explain how this cycle is generated.

Too much choice leads to riskier decisions, new study finds
The more choices people have, the riskier the decisions they make, according to a new study which sheds light on how we behave when faced with large amounts of information. Researchers at the University of Warwick and the University of Lugano set up a gambling game in which they analysed how decision-making is affected when people are faced with a large number of potential gambles.

Mathematical model 'describes' how online conflicts are resolved
Mathematical model 'describes' how online conflicts are resolved
Researchers have produced a mathematical model to describe how conflicting opinions are resolved over articles that appear on Wikipedia, the collaboratively-edited encyclopaedia. The study maps the evolution of opinion over time, showing that even widely diverging opinions eventually converge. The researchers say this pattern in collective human behaviour is reminiscent of the interaction of particles in physics, such as when wind-blown grains of sand eventually create sand dunes.
