New mathematical model shows how the body regulates potassium
Mathematical model conceptualizes the relationship between kidneys and muscles Having levels of potassium that are too high or too low can be fatal. A new mathematical model sheds light on the often mysterious ways the body regulates this important electrolyte. Potassium, a common mineral abundant in food like bananas and leafy greens, is essential to normal cellular function.

When should data scientists try a new technique?
A new measure can help scientists decide which estimation method to use when modeling a particular data problem. Close If a scientist wanted to forecast ocean currents to understand how pollution travels after an oil spill, she could use a common approach that looks at currents traveling between 10 and 200 kilometers.

Researchers derive an equation to describe how stones skim across water
A new mathematical model that predicts how a tossed stone will skim across the surface of water has potential applications in aircraft design, finds a study involving UCL researchers. The mathematical model, published in Proceedings of the Royal Society A , factors together the possible shapes and weights of a stone, the different speeds and directions of a throw and the momentum and pressure of the water as the stone impacts.

A mathematical model shows a global trend towards mutualism between species
A team led by researchers from Universidad Carlos III de Madrid (UC3M) and Universidad Politécnica de Madrid (UPM) has developed a new mathematical model to study changes in ecological interactions between microbe populations. One of the conclusions they have found is that there is a trend towards mutualism, that is, towards a relationship in which species benefit each other.

The theory of micro-hairs
Tiny hairs on cell walls, so-called -cilia-, can move in unison to pump fluid. Now there finally is a physical theory describing these hairs' movements. They are only very simple structures, but without them we could not survive: Countless tiny hairs (cilia) are found on the outer wall of some cells, for example in our lungs or in our brain.

A better way to tell which species are vulnerable
New analysis takes account of natural fluctuations and predictability to assess which parts of an ecosystem are most threatened by climate change and other disruptions. Wildfires, floods, pollution, and overfishing are among the many disruptions that can change the balance of ecosystems, sometimes endangering the future of entire species.

Mathematical link between sociopolitical event and advanced cyberattacks
An interdisciplinary team of researchers from the Universidad Carlos III de Madrid (UC3M) has created a mathematical model which makes it possible to explain, according to different sociopolitical variables, certain advanced cyberattacks that are usually carried out by States. This is a first step towards the ambitious goal of predicting the occurrence of these cyberattacks.

A new method enables the determination of the dimensionality of complex networks through hyperbolic geometry
Reducing redundant information to find simplifying patterns in data sets and complex networks is a scientific challenge in many knowledge fields. Moreover, detecting the dimensionality of the data is still a hard-to-solve problem. An article published in the journal Nature Communications presents a method to infer the dimensionality of complex networks through the application of hyperbolic geometrics, which capture the complexity of relational structures of the real world in many diverse domains.

Computational shortcut for neural networks
Neural networks are learning algorithms that approximate the solution to a task by training with available data. However, it is usually unclear how exactly they accomplish this. Two young Basel physicists have now derived mathematical expressions that allow one to calculate the optimal solution without training a network.

Better understanding of cellular metabolism with the help of AI
Metabolism is essential to all living organisms, and modeling the chemical reactions that sustain life is no easy task. Now, scientists have released REKINDLE, paving the way for more efficient and accurate modeling of metabolic processes thanks to deep-learning. The way an organism metabolizes nutrients is a complex process.

A key role for quantum entanglement
A method known as quantum key distribution has long held the promise of communication security not possible in conventional cryptography. For the first time, an international team of scientists, including researchers from EPFL, has demonstrated experimentally an approach to quantum key distribution based on high-quality quantum entanglement - offering much broader security guarantees than previous schemes.

Knots in the resonator: elegant math in humble physics
At the heart of every resonator - be it a cello, a gravitational wave detector, or the antenna in your cell phone - there is a beautiful bit of mathematics that has been heretofore unacknowledged. Yale physicists Jack Harris and Nicholas Read know this because they started finding knots in their data.

As they search for beauty
At its heart, is mathematics an aesthetic discipline? Or what does it mean if someone finds a proof -beautiful- And what does mathematical beauty say about physical connections? To this day, mathematics includes beautiful facts that are also familiar to us in everyday life. The golden ratio, for example, has been revered since an­tiquity as representing the most aesthetically pleasing proportions.
