Based on research by NASA, Finland-based Naava has developed a remotely-monitored smart wall of plants that constantly purifies indoor air, providing a fresh, clean supply.

Green roofs are a green infrastructure (GI) option that can be applied to virtually any rooftop given weight load capacity. The benefits of green roofs extend far beyond their obvious aesthetic appeal. They can capture 70 per cent of rainfall over a given time, relieving underground stormwater systems and releasing the rain water back into the atmosphere.

Gastrointestinal parasites cost the Australian sheep industry around $400 million each year with huge implications for animal welfare. The most common way of de-worming sheep is by ?drenching? them but most worm populations are now showing resistance to the drugs which are used. This drug resistance is leading scientists working with the CSIRO to look for new treatments derived from the venom of spiders. https://blog.csiro.au/sheep-parasites-spider-venom/
This system, supported by CSIRO, works by giving audio cues to cattle through solar-powered smart collars as they approach the fence and a small electric pulse if they continue on. Over a short period of time, the cows learn to turn away when they hear the audio. If they do go as far as receiving the pulse, it's significantly less than the shock of an electric fence, minimising any stress and ensuring welfare of the animals. Cleverly called eShepherd, it can be used on properties to reduce expensive fencing and keep stock out of areas that are difficult to muster or control. https://blog.csiro.au/turns-can-teach-old-young-cows-new-tricks/
