For the next six months, a camera system on the exterior of the International Space Station (ISS) will be snapping photos of more than a dozen different material samples, gathering detailed information that will help researchers determine how – and why – the harsh conditions of space affect these materials.
Derived from crude oil, toxic to synthesize, and slow to degrade, polyurethanes are not environmentally friendly. Today, researchers discuss a safer, biodegradable alternative derived from fish waste that would otherwise likely be discarded. They will present their results at ACS Spring 2021.
Grassroots knowledge from indigenous people can help to map and monitor ecological changes and improve scientific studies, according to Rutgers-led research. The study, published in the Journal of Applied Ecology, shows the importance of indigenous and local knowledge for monitoring ecosystem changes and managing ecosystems. The team collected more than 300 indicators developed by indigenous people to monitor ecosystem change, and most revealed negative trends, such as increased invasive species or changes in the health of wild animals. Such local knowledge influences decisions about where and how to hunt, benefits ecosystem management and is important for scientific monitoring at a global scale.
Polystyrene persists in the environment for millennia, according to some international governmental agencies. But now researchers have challenged this common assumption with the finding that sunlight can break down polystyrene over a much shorter time scale, from decades to centuries.
