Published Humans can recognize and understand chimpanzee and bonobo gestures, study finds



Humans retain an understanding of gestures made by other great apes, even though we no longer use them ourselves, according to a new study.
Published First computational reconstruction of a virus in its biological entirety


A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a 'live' virus.
Published Parasitic mites' biting rate may drive transmission of Deformed wing virus in honey bees


Varroa destructor is an ectoparasitic mite that can cause European honey bee colonies to collapse by spreading Deformed wing virus as they feed. A study suggests a relatively small number of mites can contribute to a large number of infected bees.
Published Researchers uncover 92 fossil nests belonging to some of India's largest dinosaurs


The discovery of more than 250 fossilized eggs reveals intimate details about the lives of titanosaurs in the Indian subcontinent, according to a new study.
Published Mummified crocodiles provide insights into mummy-making over time


Crocodiles were mummified in a unique way at the Egyptian site of Qubbat al-Hawa during the 5th Century BC, according to a new study.
Published Blowing bubbles among echidna's tricks to beat the heat



Research into how echidnas might respond to a warming climate has found clever techniques used by the animal to cope with heat, including blowing bubbles to wet its nose tip, with the moisture then evaporating and cooling its blood.
Published COVID calculations spur solution to old problem in computer science


A mathematician was keen to forecast the evolution of the COVID epidemic. Instead, he ended up solving a problem which had troubled computer scientists for decades.
Published Modelling the collective movement of bacteria


A new paper presents a mathematical model for the motion of bacteria that includes cell division and death, the basic ingredients of the cell cycle.
Published A peculiar protected structure links Viking knots with quantum vortices



Mathematical analysis identifies a vortex structure that is impervious to decay.
Published Revealing the complex magnetization reversal mechanism with topological data analysis


The reliability of data storage and writing speed in advanced magnetic devices depend on drastic, complex changes in microscopic magnetic domain structures. However, it is extremely challenging to quantify these changes, limiting our understanding of magnetic phenomena. To tackle this, researchers developed, using machine learning and topology, an analysis method that quantifies the complexity of the magnetic domain structures, revealing hidden features of magnetization reversal that are hardly seen by human eyes.
Published Finding simplicity within complexity


With the theory that for every action, even those seemingly complex and random, there is a math problem that describes it, a researcher is publishing a new formula that helps find that equation quickly. Yes, he's speeding up science.
Published Math approach may make drug discovery more effective, efficient


Researchers have devised a computer-based platform for drug discovery that could make the process more effective, more efficient and less costly.
Published Using math to better treat cancer


Researchers have identified a new method for scheduling radiation therapy that could be as much as 22 percent more effective at killing cancer cells than current standard radiation treatment regimens.
Published Moral behavior pays off


Coupling two approaches of game theory can shed light on how moral norms evolve.
Published Mathematicians explain how some fireflies flash in sync


A new study by mathematicians shows that math borrowed from neuroscience can describe how swarms of these unique insects coordinate their light show, capturing key details about how they behave in the wild.
Published Unveiling 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. A new article 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.
Published Mathematical modeling suggests U.S. counties are still unprepared for COVID spikes



America was unprepared for the magnitude of the pandemic, which overwhelmed many counties and filled some hospitals to capacity. A new study suggests there may have been a mathematical method, of sorts, to the madness of those early COVID days.
Published Music class in sync with higher math scores -- but only at higher-income schools


Music and arts classes are often first on the chopping block when schools face tight budgets and pressure to achieve high scores on standardized tests. But it's precisely those classes that can increase student interest in school and even benefit their math achievement, according to a new study.
Published Number-crunching mathematical models may give policy makers major headache


Policy makers assume that adding more detail to mathematical models will produce more accurate predictions, but that's not always the case, a new study shows.
Published Predicting risk of aneurysm rupture


Predicting the rupture of aneurysms is crucial for medical prevention and treatment. As aspect ratio and size ratio increase and an aneurysm expands, the stress applied against the aneurysm walls and the time blood spends within it increase. This leads the probability of rupture to rise. Researchers develop a patient-specific mathematical model to examine what aneurysm parameters influence rupture risk prior to surgery. Computed tomography scans are fed into the model, which reconstructs the geometry and blood flow of the aneurysm. It then uses equations to describe the fluid flow, generating information about the blood vessel walls and blood flow patterns.
