If you want to know which animals are present in a given location, a good way of finding out is to look for their cast-off DNA. A new drone is designed to help scientists do so, by autonomously sticking itself to tree branches.

Breeding plants can give them new beneficial traits, but trees have a frustratingly long reproductive cycle. Now, scientists at the University of Georgia have used CRISPR gene-editing to make poplar trees flower within months rather than a decade.

Trees can provide scientists with a way to look back into the past. Now, researchers have used tree-ring data to determine that a massive drought could have spurred incursions by Hunnic hordes into the eastern Roman Empire in the 430-450s CE.

The way animals disperse seeds throughout landscapes is known to be an important element in promoting growth of forested areas, and a new study over an extended timeframe has shed valuable new light on this process.

Tree rings can preserve a snapshot of the Earth throughout the tree's life. Now Australian scientists analyzing these records have found evidence of huge radiation storms that periodically bathe the planet – and their origin remains a mystery.

Fascinating new research from atmospheric scientists at Penn State University has found during thunderstorms, electrical discharges on tree leaves can generate significant volumes of chemicals that may affect the air quality in surrounding forests.

It has long been known that plants can help mitigate air pollution in urban environments. New research reinforces such findings, showing that "tredges" planted around schoolyards can help protect children from traffic-derived airborne particles.

Looking at big, mature trees, you may not think that their trunks sway much in the wind. They do to a certain extent, however … enough so that electronic measurement of the swaying motion can be used to monitor their growth cycles.

Wood is becoming an increasingly popular building material, but the timber is harvested mainly just from the long, straight trunks of trees. Aiming to reduce waste, an MIT team has developed a method of also using a tree's load-bearing junctions.
