Mathematicians explain how some fireflies flash in sync      (via sciencedaily.com) 

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.

A faster experiment to find and study topological materials      (via sciencedaily.com) 

Researchers have found an efficient way to identify 'topological' materials, whose surfaces can have different electrical or functional properties than their interiors. The approach should make it easier uncover materials that could be the basis of next-generation computer chips or quantum devices.

El Niño increases seedling mortality even in drought-tolerant forests      (via sciencedaily.com)     Original source 

Scientists conducted a 7-year study on seedling recruitment and mortality in a national park in Chiang Mai, in northern Thailand. During the study period, an extremely strong El Niño event occurred, leading to a stronger and longer drought than normal. Seasonally dry tropical forests (SDTFs), which experience an annual dry season, are considered drought-tolerant. Nevertheless, the study found that seedling mortality increased in SDTFs when severe and prolonged drought occurred.

Rewards only promote cooperation if the other person also learns about them      (via sciencedaily.com) 

Researchers show that reputation plays a key role in determining which rewarding policies people adopt. Using game theory, they explain why individuals learn to use rewards to specifically promote good behavior.

Unveiling the dimensionality of complex networks through hyperbolic geometry      (via sciencedaily.com)     Original source 

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.

Mathematical modeling suggests U.S. counties are still unprepared for COVID spikes      (via sciencedaily.com)     Original source 

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.

Music class in sync with higher math scores -- but only at higher-income schools      (via sciencedaily.com) 

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.

Life cycle of tree roots      (via sciencedaily.com)     Original source 

Scientists have developed a method for the direct observation of fine roots, which control the uptake of nutrients and water by trees. This provides a valuable addition to the existing knowledge of carbon and nutrient cycling in the forest floor, leading to further understanding of the carbon cycle from the view point of initial carbon input into the soil and aiding forest management and soil conservation.

UV-to-red light converting films accelerate plant growth      (via sciencedaily.com)     Original source 

Plastic sheets coated with an Eu3+ film that converts UV light to red light were able to accelerate growth of vegetal plants and trees.

By leaving garden waste alone, we could store 600,000 tons of CO2 per year      (via sciencedaily.com)     Original source 

Danes shuttle nearly a million tons of garden waste from their gardens every year. But we would be doing the climate a great service if we just left it alone, according to the new calculations. At the same time, leaves and other garden waste are a boon for backyard biodiversity and soil.

Forest recovery after Montana's 2017 fire season      (via sciencedaily.com)     Original source 

Researchers found thousands of seedlings growing after recent fires in Montana, especially at sites with cooler, damper conditions -- often found in the shade of the dead trees and upper canopy, as well as on the north side of mountains with higher elevations and more undergrowth. Researchers found fewer seedlings at sites with less shade and drier, hotter conditions.
