On top of intensifying algal blooms and depleting oxygen, a new study reveals Earth's bodies of freshwater are also evaporating at a greater rate than we realized.
Australian scientists have created the world's first-ever quantum computer circuit – one that contains all the essential components found on a classical computer chip but at the quantum scale.
A year-round variety has a real cost on the planet, with a new study finding that 'food miles' account for 19 % of all food emissions – three times more than previously thought.
