Wild horses are often viewed as alien, invasive creatures who don’t belong—but might they instead be seen as modern-day analogues of now-vanished species?
A new study shows that trees that grow faster when they are young ultimately don’t live as long as slower-growing trees. That suggests future forests will turn over too fast to lock up carbon for an appreciable length of time.
A global map reveals the huge extent of manure spread across our planet - and the untapped potential of its nutrients for our crops.
A new plastic can be broken down into its basic chemical building blocks and recycled again and again without loss in quality. Such a circular plastic could mean less new material needs to be made, and less would end up in landfills.
Efforts to restore keystone species have focused on predators and large herbivores, but another class of keystone species holds great potential for promoting life: burrowing rodents that are common but persecuted.
Climate change could increase fertility rates in tropical countries, in turn magnifying the impacts of climate change on those countries and widening the gap between wealthy and poorer nations.
Never mind the smell test: researchers have developed a new way to detect when milk has gone off, which potentially could save thousands of gallons from being glugged down the drain.
A bold vision imagines air conditioners that capture carbon dioxide and water from the air and turn it into synthetic fuels, aiding the fight against climate change and putting people in charge of their energy production.
Few conservation issues are more polarizing than the impact of free-ranging domestic cats on wild animals—but between the extremes is a common ground on which solutions can be built.
Even after being buried in the soil or immersed in seawater for three years, plastic bags marketed as biodegradable can still carry a full load of groceries without breaking.
