Not only are they in our bodies, they plague the ocean and its biodiversity and are even floating through the air. Checking microplastics The state of California Read More...
What tiny water samples teach us about huge creatures
Environmental DNA (eDNA) has been a recent gold mine in research. We recently reported on how eDNA was captured from the air in a world first and how scientists were able to use this technique to distinguish zoo animals from it. This incredible tool can help ecologists study animal behavior and Read More...
Europe’s first biorefinery uses algae to make jet biofuel
The global aviation industry is responsible for more than 2 percent of human-produced carbon dioxide emissions. To put a dent in that statistic, scientists have been actively searching for cost-effective and eco-friendly aviation fuels derived from natural resources. In recent years, microalgae Read More...
Offshore wind farms might reverse climate change effects and help sea life
As the demand for renewable energy gets higher and higher, offshore wind turbines will inevitably move further and further away from the shore. Fortunately, floating turbine technology will help facilitate this shift—but now, for the first time ever, areas of the UK continental shelf that are Read More...
This system takes CO2 from the air by taking it from the sea
The world over, researchers and scientists are looking for effective and economical ways to pull CO2 out of the air to mitigate the effects of climate change. There are many promising solutions out there, but the amount of CO2 that needs to be withdrawn is substantial and the process of pulling it Read More...
This is the UN plan to tackle plastic pollution

Automated and eco-friendly! “Green” water taxi launches in Amsterdam
In 2020, The Optimist Daily wrote about a fully automated water cab in development by the Massachusetts Institute of Technology and the Amsterdam Institute for Advanced Metropolitan Solutions. In October 2021, prototype models of the Roboat were launched and are now navigating Amsterdam’s Read More...
