Across the United States, glyphosate is applied across an enormous area of farmland each year. According to the US Environmental Protection Agency, an average of 298 million acres of cropland receives glyphosate applications annually, giving a sense of how routinely the herbicide enters agricultural landscapes.

In 1922, biologist Olaus J. Murie entered Alaska's vast wilderness to study caribou, beginning a body of field research that would eventually influence how scientists and park managers understood wildlife as part of interconnected ecosystems.

A study published in Brain Stimulation titled 'Hippocampal-network transcranial magnetic stimulation to target reactivated intrusive memories: A proof-of-concept study in PTSD treatment' has tested a new way of treating post-traumatic stress disorder (PTSD) by targeting the brain network involved in traumatic memories. Instead of stimulating a broad area linked to mood or emotion, researchers focused indirectly on the hippocampus, a brain region closely involved in forming and retrieving memories.

A gas stove can look completely harmless when its burners are switched off. There is no flame, no heat and apparently no activity at all.

Lake Erie can look deceptively uniform from the surface. Beneath it, however, temperature, oxygen and nutrients divide the water into shifting layers, creating habitats that can change over surprisingly short distances.

Modern life runs on adhesives, from the soles of shoes to the joints that hold furniture together, yet most of them share one stubborn weakness: they fail when water gets involved. A thin layer of water molecules naturally coats any submerged surface, forming a barrier that keeps conventional glue from bonding properly.

Scientists explain how floods can be prevented in Assam, from healing stripped hills to trapping sediment, restoring wetlands and mending a cross-border warning system. But they warn that no fix survives the continued mining and deforestation of the catchment.

A mosquito does not need to die for its role in malaria transmission to be interrupted. That idea sits at the centre of a 2025 study led by researchers associated with Harvard T.H.

On a warm day, a wall is usually something to escape from rather than something that helps cool a room. At Graz University of Technology in Austria, that assumption is being turned around with a ceramic structure that uses little more than water, porous clay and evaporation.

Every winter, more than 100,000 giant Australian cuttlefish can be found mating along the rocky coastline of Point Lowly, northeast of Whyalla, South Australia. They put on shape-shifting, colourful displays in their attempts to attract a mate.
