The natural world contains a yet-to-be-discovered, untapped bounty of [remedial / remedies] to help doctors. The [latest / latter] discovery comes from researchers from Georgetown University and other research institutions in the USA. They [believe / belief] their exploration of how reptiles [exert / excrete] waste could help treat human [ointments / ailments] . The scientists analysed the tiny "pee crystals" that reptiles use in place of [urine / saline] to excrete waste. The crystals are a solid form [at / of] uric acid, which is a potentially harmful [by-product / in-product] created when the body breaks down nitrogen in food. Too much nitrogen in our bodies can lead to health problems like gout and kidney [rocks / stones] . Our bodies flush most of the uric acid waste away when we [push / pass] water.

The study is published [up / in] the Journal of the American Chemical Society. A team of [organic / organist] chemists and herpetologists (scientists who study [reptiles / reptilian] and amphibians) examined [the / an] excreta and waste elimination processes of more than 20 reptile species. They focused their [attentive / attention] on the [excess / access] nitrogen that crystallised into tiny microcrystals. Researcher Dr Jennifer Swift believes the team's findings could help us better understand and [threaten / treat] uric acid-related problems like gout and kidney stones. She said: "This research was really inspired [by / to] a desire to understand the ways reptiles are able to excrete this material safely, [in / at] the hope it might [inspire / insipid] new approaches to disease prevention and treatment."
