### 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.

### 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.

### 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.

### 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.

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

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

### 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.

### Mathematical biology tackles destructive plant virus

Plant diseases pose a serious threat to global food security, especially in developing countries, where millions of people depend on consuming what they harvest. In sub-Saharan Africa, one plant disease in particular -- maize lethal necrosis -- is ravaging one of the region's preferred crops for food, feed and income. But understanding its biology in order to manage the disease is difficult because the disease arises from two viruses interacting -- which is where mathematics comes into play.

### Cow herd behavior is fodder for complex systems analysis

With closer inspection, researchers have recognized that what appears to be a randomly dispersed herd peacefully eating grass is in fact a complex system of individuals in a group facing differing tensions. A team of mathematicians and a biologist has now built a mathematical model that incorporates a cost function to behavior in such a herd to understand the dynamics of such systems.

### Mathematicians deliver formal proof of Kepler Conjecture

A mathematical problem more than 300 years old gets a formal proof with the help of computer formal verification.

### Shortcut to satellite-based quantum encryption network

Researchers demonstrate ground-based measurements of quantum states sent by a laser aboard a satellite 38,000 kilometers above Earth.

### Using light to reach higher precision in cell mechanic research

Scientists use optogenetics and mathematical modelling to identify a central molecule in cell mechanics

### Researchers refine yardstick for measuring schools

A new study has developed a novel way of evaluating and improving VAMs. By taking data from Boston schools with admissions lotteries, the scholars have used the random assignment of students to schools to see how similar groups of students fare in different classroom settings.

### How the brain recognizes what the eye sees

New work outlining the brain's visual process could improve self-driving cars and point to therapies for sensory impairment, suggest investigators.

### History of ancient geometry diagrams

A Classics student is trying to reconstruct the history of geometrical and mathematical diagrams by examining copies and translations of Elements, the ancient work of Greek mathematician Euclid.

### Innovative approaches to improve personalized radiation therapy for head and neck cancer patients

Researchers are able to use the radiosensitivity index within a mathematical framework to select the optimum radiotherapy dose for each patient based on their individual tumor biology, outlines a new report.

### Mysterious new phase of matter: Breaking glass in infinite dimensions

With the help of some mathematical wizardry borrowed from particle physics -- plus around 30 pages of algebraic calculations, all done by hand -- scientists have laid to rest a 30-year-old mystery about the nature of glass. New insights open up the possibility that some types of glass may exist in a new state of matter at low temperatures.

### Urban emissions could be cut by seventy per cent

A researcher has developed a mathematical model that determines the optimal conditions for sustainable urban distribution. The model can reduce logistical pressure in cities and make goods transport more sustainable. In some cases, it may be possible to reduce emissions in cities by seventy per cent.

### Mathematical modeling can identify ways to limit aggressive tumor cell growth

Mathematical models can be used to predict how different tumor cell populations interact with each other and respond to a changing environment, research suggests.

### A fresh math perspective opens new possibilities for computational chemistry

A new mathematical “shortcut” is speeding up molecular absorption calculations by a factor of five, so simulations that used to take 10 to 15 hours to compute can now be done in approximately 2.5 hours.

### Don't count on your chickens counting

To understand numbers, you need culture, says a cognitive scientist. He argues against the current conventional wisdom that numerical cognition is biologically endowed.
