Early life exposure to weed pollen could increase childhood asthma risk      (via sciencedaily.com)     Original source 

A study has found children who are exposed to tree and weed pollen in urban environments are at increased risk of respiratory health problems, including asthma. While green areas in urban settings decrease exposure to air pollution, allow kids to be active, and offer positive contact to a diverse microbiota -- which in turn may help the positive development of a child's immune system -- they can also lead to the development of childhood asthma. Thankfully, trees can help mitigate this effect to some degree, thanks to their canopy.

Tropical forests adjust strategies to thrive even when soils are nutrient poor      (via sciencedaily.com)     Original source 

Tropical forests store a third of the world's carbon in their wood and soils. However, their future as a carbon sink has been uncertain. Scientists have long wondered whether nutrient-poor tropical soils would limit the ability of mature and recovering forests to thrive. A study offers a hopeful response, suggesting that forests have flexible strategies that help them overcome the challenge of scarce nutrients.

Improving statistical methods to protect wildlife populations      (via sciencedaily.com)     Original source 

In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.

Meet the new insect killing Utah's fir trees      (via sciencedaily.com)     Original source 

The balsam woolly adelgid, a tiny nonnative flightless insect, is spreading across the American West killing subalpine fir in northern Utah's recreation-heavy mountain ranges and canyons. Rsearchers document a close association between the pest's spread and warming temperatures.

Simulating diffusion using 'kinosons' and machine learning      (via sciencedaily.com)     Original source 

Researchers have recast diffusion in multicomponent alloys as a sum of individual contributions, called 'kinosons.' Using machine learning to compute the statistical distribution of the individual contributions, they were able to model the alloy and calculate its diffusivity orders of magnitude more efficiently than computing whole trajectories.

Artificial intelligence tool detects male-female-related differences in brain structure      (via sciencedaily.com)     Original source 

Artificial intelligence (AI) computer programs that process MRI results show differences in how the brains of men and women are organized at a cellular level, a new study shows. These variations were spotted in white matter, tissue primarily located in the human brain's innermost layer, which fosters communication between regions.

New work extends the thermodynamic theory of computation      (via sciencedaily.com)     Original source 

Physicists and computer scientists have recently expanded the modern theory of the thermodynamics of computation. By combining approaches from statistical physics and computer science, the researchers introduce mathematical equations that reveal the minimum and maximum predicted energy cost of computational processes that depend on randomness, which is a powerful tool in modern computers.

Saturated soils could impact survival of young trees planted to address climate change      (via sciencedaily.com)     Original source 

New research has looked into the potential effects of increased rainfall in regions being earmarked for expansion of temperate rainforests. Amid global calls for more trees to be planted as part of efforts to combat climate change, this study highlights the importance of factoring in soil conditions when looking at where and how to create the temperate rainforests of the future.

AI deciphers new gene regulatory code in plants and makes accurate predictions for newly sequenced genomes      (via sciencedaily.com)     Original source 

Elucidating the relationship between the sequences of non-coding regulatory elements and their target genes is key to understanding gene regulation and its variation between plant species and ecotypes. Now, an international research team developed deep learning models that link gene sequence data with mRNA copy number for several plant species and predicted the regulatory effect of gene sequence variation.

Hurricanes jeopardize carbon-storing New England forests      (via sciencedaily.com)     Original source 

Many American companies are relying on carbon offsets to reduce their carbon footprint, especially those who have pledged to achieve 'net-zero emissions.' Sequestering carbon in forests is an example of a nature-based solution that is being used to address climate change, but a new study suggests that hurricanes could pose a risk. The results show that a single hurricane may wipe out 5% to 10% of total above-ground forest carbon, through tree damage, in New England.

Diversity and productivity go branch-in-branch      (via sciencedaily.com)     Original source 

Researchers found that forests with higher trait diversity not only adapt better to climate change but may also thrive. The study unveiled how tree functional trait diversity plays a pivotal role in mitigating climate warming. In the face of environmental stress, these diverse trees have been shown to maintain higher productivity levels, in contrast to monoculture forests.
