Reduce, reuse, recycle: The future of phosphorus
When Hennig Brandt discovered the element phosphorus in 1669, it was a mistake. He was really looking for gold. But his mistake was a very important scientific discovery. What Brandt couldn't have realized was the importance of phosphorus to the future of farming.

A group of forager-farmers in Bolivia's tropical forests — known for having remarkable cardiovascular health and low blood pressure — experienced changes in body mass and diet over a nine-year period, with increased use of cooking oil being the most notable dietary change.
Read moreWe need more realistic experiments on the impact of climate change on ecosystems
When it comes to the impact of climate change on ecosystems, we still have large knowledge gaps. Most experiments are unrealistic because they do not correspond to projected climate scenarios for a specific region. Thus, we lack reliable data on what ecosystems might look like in the future, as a team of biodiversity researchers show.

Scientists obtained a total of 733 pathogen isolates from 171 individual wild Bottlenose dolphins in Florida and found that the overall prevalence of resistance to at least one antibiotic for the 733 isolates was 88.2%. Resistance was highest to erythromycin, followed by ampicillin. It is likely that these isolates from dolphins originated from a source where antibiotics are regularly used, potentially entering the marine environment through human activities or discharges from terrestrial sources.
