Pollinators and Plants, Nature’s Perfect Pair

In Pollinators and Plants, Nature’s Perfect Pair, narrator Sir David Attenborough explores the fascinating teamwork — and clever defenses — between plants and pollinators! Monarch butterflies rely on milkweed plants for laying eggs and gathering nectar, but the plant defends itself with a sap that challenges the caterpillars. Meanwhile, the Heliconia plant carefully rations nectar to keep the hummingbird returning, as only this bird’s uniquely shaped beak can pollinate it! This video is excerpted from BBC's Life, a show that explores the remarkable strategies animals and plants use to ensure their survival.

Checking Water Pollution? There's an App for That

When it comes to gathering water data, the “employee of the month” may look a little on the “green and cubical” side. Alongside Yorkshire rivers, there are multiple green boxes working hard to gather data on river quality that should, in a couple years, be available for river users and potential swimmers to access through an app that tracks pollution. 

Though there are currently apps that show pollution data, that information is old and outdated. This upcoming app is special, because it will use live data from an on-site sensor to provide real-time pollution levels in the water. It’s not meant to tell people “safe” or “not safe” or “swim” or “don’t swim,” but it can give people what they need to make an informed decision... mostly. 

The green boxes have a big shortcoming: they’re unable to detect some really nasty bacteria like E.coli, which can only be measured in a lab. But don’t worry, old-school scientists are on the case, manually taking samples to send away for analysis. These findings will be used to build a data set that will be combined with green box data, and AI learning will infer when E.coli (and other bugs) are present in the river. 

So, today, we celebrate a beautiful marriage —  one of traditional testing, new technology, and AI. It may not be the pairing you’re rooting for on Love Island, but it shows great promise for water safety!

Therapy Dogs in Uganda Are Changing Lives

Don’t you hate it when you’re late for work, but you just can’t find your bone and lunch bag of kibble? That may be the case for a group of dogs in Gulu, Northern Uganda, who work as therapy dogs, helping people with tough upbringings navigate their trauma and adjust to a happy life. To support a population that grew up in a war (and the unsafe conditions that came with it), a charity has paired them with dogs.

What’s better? The dogs benefit, too! We’re not talking about an end-of-the-week paycheck or big office parties, but something better: overdue love and affection. All the dogs are former street dogs, so they weren’t properly cared for, and these have helped more than 120 people and dogs find healing bonds with each other.
