Phosphorus and nitrogen contribute to water pollution and cause harmful algal blooms. New research shows how mats of floating flower beds can take advantage of these nutrients while cleaning the water.
Phosphorus is the most elusive element crucial for life as we know it – and we now have the first evidence there’s some available in the oceans of Enceladus.

Nutrient pollution fouls lakes and bays with algae, killing fish and threatening public health. Progress curbing it has been slow, mainly because of farm pollution.
Farmers are contending with huge spikes in fertilizer prices. The Biden administration is paying US companies to boost synthetic fertilizer production, but there are other, more sustainable options.
Studying these deposits gives scientists information about how past environments change. That, in turn, gives us informed estimates on how climates and environments will change in the near future.
Harmful algae blooms are an increasing problem in Florida. Once nutrients are in the water to fuel them, little can be done to stop the growth, and the results can be devastating for marine life.
The spread of tawny crazy ants may be driven, in part, by their need for calcium. The calcium-rich limestone bedrock of the lower U.S. Midwest may provide ideal conditions for populations to explode.

If rolled out worldwide, our method could replace a quarter of all the synthetic nitrogen fertiliser used in agriculture.
Global phosphate production is set to peak in 2030, around the same time the world’s population will reach nine billion. As a finite resource, a phosphate shortage will effect global food production.
The elements that make up each column of the periodic table share a set of common traits. Here, a chemist describes group 15 and the crucial role phosphorus, in particular, plays in cancer.
The ‘used water’ that flows from our showers, dishwashers and toilets isn’t a waste to engineers – it contains valuable materials. The challenge is recovering them and turning them into products.
Originally found in a bucket of urine by an alchemist searching for the elixir of life, the race is on to find a way to rescue Element 15 from permanent exile in our rivers and streams.
