### Malware infecting hard disk firmware remained hidden for 15 years – but who's responsible?

It sometimes seems that whenever security researchers discover some new exploit or malware that allows the monitoring of remote computers, the finger is quickly pointed at the US intelligence agencies.

### Adding uncertainty to improve mathematical models

Mathematicians from Brown University have introduced a new element of uncertainty into an equation used to describe the behavior of fluid flows. While being as certain as possible is generally the stock and trade of mathematics, ...

### On the origins of the Schrodinger equation

(Phys.org) —One of the cornerstones of quantum physics is the Schrödinger equation, which describes what a system of quantum objects such as atoms and subatomic particles will do in the future based on its current state. ...

### Taming the Boltzmann equation

Physicists at Ludwig Maximilian University of Munich, Germany, have developed a new algorithm that is capable of solving the Boltzmann equation for systems of self-propelled particles. The new method also reveals previously ...

### Study examines impact of domestic violence intervention

It is estimated that nearly 25 percent of women will experience severe violence at the hands of an intimate partner. The first step to seek help: call the police.

### A mathematical theory proposed by Alan Turing in 1952 can explain the formation of fingers

Alan Turing, the British mathematician (1912-1954), is famous for a number of breakthroughs, which altered the course of the 20th century. In 1936 he published a paper, which laid the foundation of computer science, providing ...

### Optimized application of high intensity focused ultrasound

The field of nonlinear acoustics is currently receiving a lot of attention, thanks to applications focused on the improvement of ultrasonic cleaning, ultrasonic welding, sonochemistry, or thermotherapy. Lithotripsy – the ...

### Insightful mathematics for an optimal run: Mathematical equations can help improve athletic performance

Sure, we can become better runners by hydrating well, eating right, cross training, and practice. But getting to an optimal running strategy with equations? That's exactly what a pair of mathematicians from France propose ...

### Strange physics turns off laser

Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter.
