Elephant-friendly alternative to ivory can be 3D-printed to restore art
Although there has been a ban on international ivory trading since 1989, tens of thousands of elephants are still poached for their tusks every year, a trend that’s slowly pushing some endangered species to the brink of extinction. A team of scientists has recently developed a high-quality ivory Read More...

Pair of brothers set record for longest highline walked in Yosemite
Yosemite National Park has long been a site for the daring and determined and now, a pair of brothers from San Francisco claim to have successfully walked the longest Highline ever within the park. Moises and Daniel Monterrubio recruited a group of friends to help them string up a 2,800 ft line Read More...
Scientists use a 3D printer to create a living material made from algae
Being some of the most productive organisms on Earth, it’s no wonder that algae are the subject of intense study in the scientific community. We have previously written many stories about these miracle organisms and their incredible qualities, such as sequestering greenhouse gases and Read More...
Bee-friendly wildflower meadows are blooming across Germany’s biggest cities
Germany is home to about 580 wild bee species, most of which have their habitat in urban areas. More than half of these species are endangered or on the brink of extinction. The increased use of insecticides, exposure to noxious exhaust fumes, and above all a loss of diverse habitats, are the main Read More...
Mangroves roots inspire scientists to develop efficient water purifier
While solar stills have been around for some time already, there’s plenty of room for efficiency improvements. In a bid to do exactly that, scientists from Virginia Tech have developed a mangrove-inspired “synthetic tree” that mimics the natural process of transporting water from the roots to Read More...
Beyond seawalls: How oysters can more sustainably protect our coastlines
We’ve written at length about using natural materials to restore degraded coastlines. The strong natural composition of oysters makes them a popular choice for these projects and in Southern California, one scientist is combining native oysters with the power of seagrass to promote coastline Read More...
Drones help protect biodiversity on Galápagos Islands by ridding them of rats
The biodiversity of Seymour Norte and Mosquera, two Galápagos Islands, has been threatened for generations by a commonly abhorred pest: rats. Two rat species (the black rat and the Norweigan rat) have disrupted the ecosystems on the islands of Seymour Norte and Mosquera since they arrived on Read More...
Ghana takes on ambitious reforestation effort to plant at least 5 million trees
Just over a week ago, people in Ghana decided to take on the impressive initiative of planting at least five million trees under the “Green Ghana” program. The launch of the project follows the expansion of mining and agriculture that, according to environmentalists, has led to an Read More...
