A team of scientists from the University of Portsmouth have developed new scientific tests to better understand the effects of pollution on wildlife behaviour.

Earlier this year, a three-year-old video of researchers extracting a long, twisted tube from a reptile’s bleeding nostril went viral. To date, it has accumulated more than 30 million views and set off a moral panic.

Rice University scientists have released the first results of extensive water sampling in Houston after the epic flooding caused by Hurricane Harvey. They found widespread contamination by E. coli, likely the result of overflow from flooded wastewater treatment plants.

Add just enough fertilizer, and crops thrive. Add too much, and you may end up with contaminated surface and groundwater.

In a perspective published in the July 20 issue of Science, Neal Stewart and his University of Tennessee coauthors explore the future of houseplants as aesthetically pleasing and functional sirens of home health.

Scientists have identified 22 key research questions surrounding the risks associated with chemicals in the environment across Europe.

Degradation rates of oil were slower in the dark and cold waters of the depths of the Gulf of Mexico than at surface conditions, according to an international team of geoscientists trying to understand where the oil went during the Deepwater Horizon oil spill.

The air in US national parks contains just as much ozone pollution as the air in many of the country’s largest cities, according to a study published on 18 July in Science Advances.

The spring morning temperature in landlocked northern California warns of an incipient scorcher, but the small herd of piebald dairy cows that live here are too curious to care. Upon the approach of an unfamiliar human, they canter out of their barn into the already punishing sun, nosing each other aside to angle their heads over the fence. Some are black-and-white, others brown; all sport a pair of numbered yellow ear tags. Some are more assertive than others. One manages to stretch her long neck out far enough to lick the entire length of my forearm.

Along the Houston Ship Channel, a 52-mile waterway that spills into the Gulf of Mexico, giant vessels cruise beneath the blazing summer sun. Rusty tankers fill their holds with Texas specialties: refined oil products, petrochemicals, and plastic resins. Container ships arrive carrying corrugated boxes of imported T-shirts, electronics, and metals.
