The mega-berg that last year threatened one of the world's largest marine nature reserves is no more. Measuring an incredible 2,187 square miles when it broke off Antarctica in 2017, iceberg A-68a has now disintegrated into fragments too small to track.

Just like a tree trunk, the tusk of the narwhal acquires a new growth ring every year. Analyses of those rings have now revealed some interesting facts about the animals' diet, and about changes in their environment.

In the event of a global catastrophe, how would we protect the wide variety of plants and animals on Earth? A team of researchers has now proposed a “Noah’s Ark” on the Moon that stores millions of samples of seeds, spores, sperm and eggs.

A little over two years after Israel-based start-up Aleph Farms unveiled the world’s first lab-grown steak, the company has now revealed a much more complex, thick-cut rib-eye steak cultivated using a novel 3D bioprinting technology.

Unfortunately concrete production is a major source of carbon dioxide in the atmosphere. Now engineers at Purdue University have developed a new cement recipe that can absorb CO2 twice as fast as usual, hopefully turning it into a useful carbon sink.

As part of its goal to reach net zero carbon dioxide emissions by 2050, Rolls-Royce has begun testing 100-percent Sustainable Aviation Fuel (SAF) in a small commercial business jet, which could lead to lifecycle emissions reductions of over 75 percent.

An environmental disaster may have been averted as images from ESA's Copernicus fleet of satellites show the giant iceberg A-68a turning away from South Georgia Island and starting to break up into smaller bergs.

A team has developed a process that turns waste plastic into an adhesive that's more valuable. The goal was to find ways to "upcycle" plastics by putting them to new uses while preserving the properties that made them attractive in the first place.

The giant iceberg A-68A that is threatening the island of South Georgia in the South Atlantic has split into three pieces and is thinning by one inch per day. If the bergs run aground they could cause considerable environmental damage.

The giant iceberg A-68a is likely to ground itself in the shallows of South Georgia island, so a scientific expedition is getting ready to visit the site to determine the impact of the event on the local ecology using underwater glider robots.

After an almost complete absence for 50 years, blue whales are returning to the waters surrounding South Georgia island in the south Atlantic. A study has collected 58 sightings of the giant cetaceans as well as acoustic soundings of their presence.

Lightning is a major trigger for wildfires, like the record-breaking blazes that devastated Australia and California this year. But what if we could redirect lightning to strike safely? Graphene particles trapped in a tractor beam could do just that.
