Every time it rains, fish living downstream of storm drains are exposed to pollutants, including the tire-derived compound 6PPD-quinone, in the runoff. Recently, this substance has been linked to massive die-offs of coho salmon across the U.S. West Coast. Now, researchers report that exposure to 6PPD-quinone at environmentally relevant levels...

Abrupt shifts in the evolution of animals -- short periods of time when an organism rapidly changes size or form -- have long been a challenge for theorists including Darwin. Now a newly published research paper supports the idea that even these abrupt changes are underpinned by a gradual directional...

Tapping into groundwater can help communities in Africa diversify their water supply and strengthen their drought defenses, according to a new study.

A study has confirmed what is believed to be the first published account of the delta variant of SARS-CoV-2 in a house cat. The viral sequence was a close match to strains circulating in the Philadelphia area at the same time, underscoring the virus's ability to jump from one species...

Scientists used an emerging genetic tool that analyzes DNA in water samples to detect whales and dolphins in New York waters.

Genes jumping from microbes to green algae hundreds of millions of years ago might have driven the evolution of land plants, researchers report. Their analysis reveals that hundreds of genes from bacteria, fungi, and viruses have been integrated into plants, giving them desirable traits for a terrestrial life.

Using a unique hydrogel, scientists have created a solar-driven system that successfully grows spinach by using water drawn from the air while producing electricity. The proof-of-concept design offers a sustainable, low-cost strategy to improve food and water security for people living in dry-climate regions.

Researchers have developed a new technique by studying the age of ancient grains of sand from beaches, rivers and rocks from around the world to reveal previously hidden details of the Earth's distant geological past.

A team of researchers is developing tools to predict the features of life as we don't know it.

A new, highly sensitive system for detecting the production of hydrogen gas may play an important role in the quest to develop hydrogen as an environmentally friendly and economical alternative to fossil fuels.
