Want to keep sharks and beachgoers safe? There’s an app for that

Sharks, as top predators, are a keystone species. This means the balance of whole marine ecosystems relies heavily on sharks' well-being. Protecting and conserving sharks is of the utmost importance, especially since they already face many threats to their survival such as the illegal shark fin Read More...

Dolphins are using coral as a skin treatment

New research suggests that dolphins rub up against coral for more reasons than scratching a hard-to-reach itch. The cetaceans, which are known to rub against the rough surfaces of coral, take naps in coral beds, and enjoy soaking on sponges along the reef may actually be using the coral to treat Read More...

Scientists discover prehistoric dolphin species in landlocked Switzerland

Paleontologists have recently made an extraordinary discovery in landlocked Switzerland: two new species of dolphin dating back to 20 million years ago. Ancient dolphin species  Located in the heart of Europe, Switzerland is entirely landlocked. Millions of years ago, however, the area used to Read More...

Study reveals planktons' unexpected resilience to global warming

With our changing climate, protecting all impacted organisms on Earth is a huge priority. The planet has gone through previous cycles of heating and cooling, and looking at these periods can give us clues about what may happen. An international team of researchers has done just that, by studying Read More...

Scallop-attracting LED “disco” lights lead to more eco-friendly fishing technique

Marine scientists have accidentally stumbled upon an unexpected technique for catching scallops that has the potential to reduce some of the environmental damage caused by conventional fishing practices. Dr. Rob Enever, a specialist in reducing the impacts of fishing on the marine environment, Read More...

How the Belize Barrier Reef is coming back to life

When Hurricane Iris hit Belize in 2001, it ravaged almost all of the country’s coral reefs. The devastation signaled bad news not only for the surrounding marine life but also for the local communities who rely on reefs for food, work, and protection from storms and erosion. Now, thanks to a Read More...

“Blue Corridors”: using science and animal instinct to save fish populations

We’ve all marveled at the intrepid salmon swimming against the current, up waterfalls, and avoiding predators to return to its native spawning grounds, or at least we’ve all seen it on a nature show. This behavior is called philopatry, an animal’s tendency to return to its area of birth, and Read More...

New desalination system uses Teflon-like membrane to make seawater potable

Clean drinking water is already in short supply in many places around the world, but the situation is only expected to get worse with climate change. Figuring out ways to desalinate brackish water or seawater in an efficient and scalable way is key to mitigating the global water crisis. A Read More...

Hawaii-based startup unveils world’s first ocean carbon-removing machine

Cutting greenhouse gas emissions at the source should be the main goal when tackling climate change, but the most recent IPCC report also recommends carbon capture and storage technologies as key parts of the effort to limit global warming to 1.5°C. The startup Heimdal is well aware of the need Read More...
