Urine is the result of a fascinating and complex system, of which the kidneys are the star, that evolved to keep our internal ...

Laboratories use a variety of tests to analyze urine samples. These include pH measurement, specific gravity checks, and chemical composition analysis. High-end synthetic urine mimics all these ...

Urine is rich in nitrogen, which is important for plant growth, and now scientists have found an efficient way of utilising this to make human wastewater into fertiliser ...

That device takes in urea, which is present in urine, and uses it to generate a useful electrical charge. [Josh] has, of course, named this device the P Cell. An early proof of concept uses urine ...

Urine contains water, urea and salts. Urea is produced in the liver when excess amino acids are broken down. Urea is the main waste product removed in the urine, as it is not reabsorbed in the kidney.

a derivative of urea, bypassing the need for complex purification steps and transforming waste into a valuable product. Their process, showing the possibility of percarbamide extraction from human and ...

A more efficient way to extract fertiliser from human urine could help make better use of wastewater in cities and farms, without exacerbating global warming. Human urine is rich in compounds ...

The molecules which are not selectively reabsorbed (the urea, excess water and ions) continue along the nephron tubule to the collecting ducts as urine. This eventually passes down to the bladder.
