THE POO FILES
Faeces, excrement, poop or poo - what ever you call it, it's not something most of us like to discuss. For scientists it is a vital source of data and clues! So…

Aim Children frequently ingest coins (generally with minimal reported side effects); however, the ingestion of other items has been subject to less academic study. Parental concern regarding ingestion applies across a range of materials. In this study, we aimed to determine typical transit times for another commonly swallowed object: a Lego figurine head. Methods Six paediatric health‐care professionals were recruited to swallow a Lego head. Previous gastrointestinal surgery, inability to ingest
Cool news: Penguins are as Kiwi as pavlova and jandals. For years scientists thought penguins originated in Antarctica but new research suggests they first evolved in the cold coastal regions of Aotearoa and Australia about 22 million years ago. Kid reporter Houston Ramea, 9, talks to one of the scientists behind the discovery about what it means, and why big penguin poo stains seen from space can be good news for our newly minted locals.
Urban areas around the world are feeling the weight of growing populations. While cities can become hotspots for economic opportunity, they also churn out massive amounts of waste. Untreated waste that returns to the earth can be unsafe – and a waste of precious nutrients. But now there are ways to not only treat that waste, but to turn it into something new. Resource recovery and reuse (RRR) is transforming waste management. And the start of this show? Fecal sludge.
Scion has created a new sewer-less toilet with a high-tech back end that can treat human waste in a new, safe, sustainable and affordable way. The toilet and its built-in waste treatment tech is Scion’s answer as a successful participant in the Reinvent the Toilet Challenge initiated by the Bill & Melinda Gates Foundation. The challenge was created to develop solutions for developing countries where sanitation-related problems are a leading cause of child mortality.
"Our data suggest the possibility of extended duration of viral shedding in faeces, for nearly 5 weeks after the patients' respiratory samples tested negative for SARS-CoV-2 RNA. Although knowledge about the viability of SARS-CoV-2 is limited, 1 the virus could remain viable in the environment for days, which could lead to faecal–oral transmission, as seen with severe acute respiratory virus CoV and Middle East respiratory syndrome CoV.2 Therefore, routine stool sample testing with real-time...
Phosphorus is an essential element for life. Forms of it are found in DNA, RNA and all living cell membranes. It is the sixth most abundant element in any living organism. Phosphorus can also be highly poisonous and combustible (white phosphorus is used in many destructive weapons, such as napalm). It was also the first element discovered since ancient times. The person who made this discovery was Hennig Brand in 1669, who did so while he was playing around with large amounts of human urine.
When a baby Beaded Lacewing Lomamyia latipennis gets hungry, it stuns a termite with a "vapor-phase toxicant" released from its anus. That's a fancy way of saying it farts on it. In fact, their farts are powerful enough to immobilize six termites with one blow. This is how you wield a Death Fart, if you are a small predatory neuropteran...
Latin continues to provide exact and elegant expressions that have become standard in the international scientific community. Think of in vitro and in vivo. Here, we propose in fimo to indicate samples derived from human and animal excrement and examined scientifically. The importance of material extracted from excrement for study has recently become clear. We have proposed the in fimo terminology in a submitted manuscript and have been using it in international presentations...
From dino droppings to gut microbes to square poop, you can learn a lot by studying poos. Study something in a test tube, and scientists say that the research was performed in vitro. That’s Latin meaning “in glass.” Study it in a living body, and it’s in vivo (“in a living thing”). But what if your research has you poking around in poop? Scientists haven’t had a word for that — until recently. Introducing in fimo. This new scientific term describes experiments done on feces.
Can snails fart? Thank you. – Avalon, age 9, Scotts Head, NSW. Lots of animals fart because of what they eat, but it was not easy for me to find a clear answer on whether snails really do. More research is needed to know exactly how the digestive system of a snail really works. You might have heard about methane. It is a gas found in a lot of animal farts. I did find one study that said that scientists kept some snails in a glass container ...
