How Fire Coral has an Edge Over Other Species in the Caribbean Reef

Posted on by Riley Bell

Coral reefs are the most productive marine ecosystem known, providing essential habitats and shelters for fish and other organisms. Additionally, they help protect coastlines, support economies, provide important food sources for local fisheries, and so much more. Coral reefs are ecologically essential—but are continuing to vanish. Fire coral (Millepora) brings new hope to this marine crisis due to their unusual ability to grow in two forms and survive under various habitat stresses.

What Is Fire Coral?

Fire coral has been around for millions of years and is most commonly found in sunny, shallow reefs. They tend to grow in tropical and subtropical waters with many thriving in different areas of the Caribbean Sea, one of the planet’s most biologically diverse ecosystems. Fire coral resembles typical stony corals but has a wicked sting that can cause burning skin reactions, reflecting their relationship as a close relative to jellyfish.

Explore the World From a New Lens with Nature Photography

Posted on by Riley Bell

Each year, on June 15, we celebrate Nature Photography Day. This globally recognized day was designated by the North American Nature Photography Association (NANPA) to embrace the value of nature and encourage the enjoyment of nature photography.

Photography helps us explore the natural world and advance conservation efforts to protect plants, nature, and wildlife both locally and globally. One of the great things about Nature Photography Day is that you can participate wherever you are, with whatever equipment you have—nature is all around us!

Cell-Free Artificial Photosynthesis with Frog Foam

Posted on by Michele Arduengo

We owe a lot to frogs and toads. They help us welcome in spring and summer with their peeps, croaks and snores in the evenings. They serve as bioindicator species that alert us to damaged or toxic environments. And, now, they may even help us kick the fossil fuel habit through an artificial photosynthesis matrix.

Biofuels, based on harvesting and converting plant biomass to fuel have been touted as an alternative to nonrenewable fossil fuels. The argument for them goes something like this:  Nature has a means for converting sunlight energy to chemical energy (photosynthesis). Why not just let Nature do the work for us, and harness that power?
