Over the past 30 years, Australia’s Great Barrier Reef has experienced a 50 percent loss in coral. Though part of the decline is being attributed to the warmer ocean temperatures caused by climate change, about half of the damage is due to the proliferation of the crown-of-thorns starfish (COTS). The deadly predators can devour as much as 53 square feet (five square meters) of live coral annually.

Burying time capsules for future civilizations is not a new concept. However, the one hidden underground near the Polish Polar Station in Hornsund, Spitsbergen, in the Norwegian Svalbard archipelago, is a little unique. Instead of detailed documents to showcase our progress and knowledge, the capsule contains objects, which the creators believe will be easier for future historians to interpret.
After providing the world with spectacular close-up images of Pluto and its icy moons in the summer of 2015, NASA’s New Horizons is zipping off into uncharted territory a billion miles away. On January 1, 2019, the spacecraft will fly past the most remote world ever explored by mankind. Dubbed (486958) 2014 MU69, the small frozen object that lies in the Kuiper Belt may help scientists reveal the origins of our solar system. To mark this historic event, the US Space Agency is asking the public to help find a nickname that is easier to remember than the elaborated moniker assigned by researchers.
While a wild cat chasing down prey sounds perfectly reasonable, one who sprints to fetch sticks might seem a little bizarre. However, that is precisely what Serabie, a rescued adult lioness at the Emoya Big Cat Sanctuary in South Africa’s Limpopo province, loves to do.
Before astronauts embark on a mission to Mars, it is imperative for scientists to know everything they can about the impact of long-term space travel on the human body. Previous studies have shown that extended exposure to microgravity causes muscles and bones to weaken, deteriorates vision, and, in some cases, even alters the astronaut’s DNA. Now, there is evidence that spending a long time in space could also permanently change the brain’s structure.
On September 28, 2017, LEGO fans of all ages finally got the chance to visit the massive 82,000 square-feet, 100-feet high, LEGO house aka “Home of The Brick.” Located in the iconic toy’s hometown of Billund, Denmark, the impressive structure, that has been in the works since 2014, is the brainchild of Danish architect Bjarke Ingels. Its exterior, resembling 21 gigantic LEGO blocks, is covered in colorful tiles giving the illusion that the entire building is made of the popular bricks. A 2X4 keystone brick placed on top welcomes visitors flying into Billund Airport with light beams from its eight knobs.
Flat Holm, a small limestone island in Britain’s Bristol Channel, has no permanent residents and minimal infrastructure. The area’s low energy needs have therefore been fulfilled using old-fashioned solar panels and a diesel generator. The picturesque landmass is now, however, becoming increasingly popular with tourists wishing to explore the rustic landscape and view the island’s seabird colonies.
