### One step closer to halting the spread of Zika, Dengue, Chikungunya

A mathematical model can serve as a guide to make monthly predictions on when people are at greatest risk for contracting mosquito-borne viruses, such as dengue, Zika and chikungunya, due to climate conditions, scientists report. more...

### Decision-making rules least susceptible to manipulation, according to science

Computer modelling has been used to demonstrate the varying manipulability of decision-making procedures and to identify those least susceptible to manipulation. more...

### Making telescopes that curve and twist

A new tool for computational design allows users to turn any 3-D shape into a collapsible telescoping structure. New mathematical methods capture the complex and diverse properties of such structures, which are valuable for a variety of applications in 3-D fabrication and robotics -- particularly where mechanisms must be compact in size and easily deployable. more...

### Into the quantum world with a tennis racket

Quantum technology is seen as an important future-oriented technology: smaller, faster and with higher performance than conventional electronics. However, exploiting quantum effects is difficult because nature's smallest building blocks have properties quite distinct from those we know from our everyday world. An international team of researchers has now succeeded in extracting a fault tolerant manipulation of quanta from an effect of classical mechanics. more...

### Using mathematical methods to study complex biological networks

Complex biological processes, such as the metabolism, often involve thousands of different compounds coupled by chemical reactions. These process chains are described by researchers as chemical reaction networks. Researchers have developed new mathematical methods to study the energetic properties of these networks. more...

### Algorithm generates optimal origami folding patterns for any shape

A new algorithm generates practical paper-folding patterns to produce any 3-D structure. more...

### Mathematical method for fair definition of electoral districts

For democratic elections to be fair, voting districts must have similar sizes. When populations shift, districts need to be redistributed -- a complex and, in many countries, controversial task when political parties attempt to influence redistricting. Mathematicians have now developed a method that allows the efficient calculation of optimally sized voting districts. more...
