The nearly 400-year-old history of oaks in South Africa may be coming to an end, forever changing the treescape of towns and cities such as Cape Town, George, Paarl, Stellenbosch, and Swellendam. In a research paper published in the South African Journal of Botany, ecologists from the Centre for Inv...

Trees are struggling to sequester heat-trapping carbon dioxide (CO2) in warmer, drier climates, meaning that they may no longer serve as a solution for offsetting humanity’s carbon footprint as the planet continues to warm, according to a new study led by Penn State researchers. “We found that trees...

Recent genomic research suggests that baobabs originated in Madagascar and later dispersed to Africa and Australia. Factors like climate and sea level changes influenced their evolution. Rising sea levels threaten their expansion, necessitating urgent conservation. Some species may be reclassified a...

Climate change impacts tree migrations by disrupting essential symbiotic relationships with mycorrhizal fungi, necessary for nutrient exchange and survival in new habitats. As our planet warms, many species are shifting to different locations as their historical habitats become inhospitable. Trees a...

New research reveals that tree bark microbes absorb significant amounts of methane, increasing the climate benefit of trees by about 10%. This finding underscores the importance of trees in mitigating climate change and supports tree planting and forest conservation as key strategies in global metha...

Hello Hacker News.<p>I’m Martin, a graduate student from Prague, and I’ve been working on Coros, a C++ library for task-based parallelism.<p>After spending some time with OpenMP and oneTBB, I wanted to try building a library using modern features from the C++ standard library. I’ve used coroutines f...

Scientists at NC State University have discovered how modifying lignin in trees using CRISPR can make them better suited for microbial fermentation to produce chemicals sustainably. This breakthrough could replace the need for petroleum-based chemicals, offering a greener alternative that is both ec...

A group of international scientists contends that planting trees at high latitudes will accelerate global warming rather than slow it down. Tree planting is often promoted as a cost-effective strategy to combat global warming, thanks to trees’ capacity to absorb significant amounts of atmospheric ca...

Biologists at UC Davis have uncovered a fascinating genetic mechanism in walnut trees, allowing them to alternate between male and female flowers each season—a trait stable for 40 million years. This discovery not only sheds light on plant reproduction but also parallels mechanisms in human sex dete...

Blue growth rings in woody plant stems indicate years when cells failed to lignify properly due to summers that were too cold for normal growth. When temperatures drop, even tough trees face challenges in growing. Trees require a specific number of warm days during their growing season to develop pr...

A recent study details the genome of the highly prized white oak. The white oak (Quercus alba) is a keystone species in eastern North American forests, valued for its economic, ecological, and cultural significance. Despite its abundance, the species is experiencing a decline in seedling recruitment...

In the chilly winters of British Columbia, sweet cherry trees employ a fascinating survival trick called supercooling, allowing their flower buds to stay unfrozen even in sub-zero temperatures. But this delicate balance can be shattered by a sudden cold snap, as seen in January 2024 when extreme wea...

Trees near volcanoes might be the early warning signs scientists have been looking for — and now, they can be watched from space. A NASA-Smithsonian collaboration has revealed that carbon dioxide released from rising magma makes surrounding vegetation greener, a subtle but trackable signal. Using sa...
