After almost two years of traveling through space, on September 22, 2017 NASA’s OSIRIS-REx (Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer) made its closest flyby of Earth. Moving at speeds of about 19,000 mph, the spacecraft passed within 11,000 miles of the planet’s surface just south of Chile, before zooming over Antarctica. The carefully orchestrated encounter was designed to take advantage of the Earth’s gravity to help launch OSIRIS-REx towards a tiny asteroid named Bennu. Referred to as the slingshot effect, or gravity assist, the ingenious method helps propel spacecrafts to great distances without expending precious fuel.

With the New Year just weeks away, you are probably looking forward to watching the dazzling fireworks shows that will usher in 2018 worldwide. Unfortunately, the over ten million visually impaired and blind Americans, and scores more around the globe, have never been able to experience this joyful celebration. That may change soon thanks to Feeling Fireworks, a tactile fireworks experience invented by the masterminds at the Disney Research Lab in Switzerland.
The United Arab Emirates (UAE), a federation of seven monarchies on the Arabian Peninsula, is mostly a desert. However, this has not deterred the leaders from setting and achieving lofty goals that include massive building projects, most bordering on the impossible. Dubai, the UAE’s largest and most populous city, is home to the world’s tallest building, the world’s biggest mall, as well as the world’s second largest choreographed fountain system. On September 26, UAE officials announced yet another ambitious project – a space simulation city, the world’s largest of course!
Facial recognition is a complex task which requires as many as 200 neurons in the brain’s temporal lobe, called “face patches,” to fire up simultaneously within milliseconds. Hence the skill has always been believed to be the realm of “intelligent” animals such as humans, monkeys, apes, dogs, and horses. Now, British scientists have found that the unassuming cud-chewing sheep also possess this skill.
Since 2015, members of the Incredible Science Machine have been mesmerizing fans with their complex chain reactions using tens of thousands of dominoes and props. This year was no exception. On March 23, the team set into motion their latest spell-binding creation that culminated in the toppling of a massive centerpiece comprising 76,017 dominoes.
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.
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.
