Representative Image (AI-generated) A tiny concentration of a synthetic hormone was enough to trigger a dramatic ecological change in a remote Ontario lake.

The experiment continued for seven years,…

Deep in the Caxiuanã National Forest in northern Brazil, a patch of rainforest the size of a football pitch tells the story of what a drier Amazon might look like. Since 2002, scientists have suspended nearly 6,000 transparent plastic panels above one hectare of pristine forest, diverting roughly half the rainfall away from the soil…

In 2010, scientists with the U.S. Geological Survey (USGS), working with the Montana Department of Environmental Quality, conducted a dye-tracing experiment on a 41.2-mile…

A green mamba specimen from São Tomé Island that dates back to 1885 has been found after decades of being regarded as lost, which gives scientists a rare opportunity to revisit the identity of one of the Gulf of Guinea’s most mysterious snakes.
