The world’s most widely used weed killer may also be indirectly killing bees.

Building on a century of hydroscience research, the University of Iowa enters a new era of activity aimed at solving Earth’s biggest environmental issues.

Artificial light at night also makes guppies more courageous during the day, according to a behavioural study led by researchers from IGB and the Max Planck Institute for Human Development. Exposing fish to artificial light at night, not only made fish more active during the night, but also made them emerge quicker from hiding places during the day, which could increase their exposure to predators. Nocturnal lighting, however, did not affect their swimming speed or social behaviour during the day.

In September 2015, the German automaker Volkswagen was found to have illegally cheated federal emissions tests in the United States, by intentionally programming emissions control devices to turn on only during laboratory testing.

Killing germs around the house may have a surprisingly negative impact on young children’s waistlines.

With sea ice in the Arctic melting at an alarming rate, opportunities for trans-Arctic shipping are opening up, and by mid-century ships will be able to sail right over the North Pole – something not previously possible for humankind.

University of British Columbia researchers studying the marine food web of the Northeast Pacific Ocean have found that the exposure and accumulation of chemical pollutants, such as polychlorinated biphenyls (PCBs) and organic mercury, will be exacerbated under climate change.

Oysters likely suffered toxic effects from the oil dispersant Corexit® 9500 when it was used to clean up the 2010 Deepwater Horizon oil spill, said Morris Animal Foundation-funded researchers at the University of Connecticut.

Committed to addressing the country’s severe air pollution, China is attempting a shift from coal to natural gas and is considering a variety of sources, including domestic and imported gas options as well as creating its own synthetic gas from coal.  

Nothing against the countryside, which is lovely, but cities are where things happen. They are magnets for trade, and they're where cultures meet. They're also where more than half the world’s population lives, a number that will only continue to grow.
