Think the prices at your neighborhood coffee shop are a little steep? Then you might want to avoid visiting the South American country of Venezuela, where the cost of a cup of coffee has risen more than tenfold, from a “reasonable” 190,000 bolivars in April 2018, to over 2 million bolivars in August 2018. What’s worse is that if the July 26, 2018 report from the International Monetary Fund forecasting a 1,000,000 percent annual inflation rate is correct, the caffeine fix could set the country’s residents back an astounding 5 million bolivars per cup by September! Welcome to Venezuela’s hyperinflated economy!...

Just a few decades ago, humans were the only species believed to be smart enough to grasp the concept of zero — the idea that nothing can be counted as something. While a select group of animals, including dolphins, primates, and a few birds, have since been added to the list, experts have always maintained that only “intelligent” species are capable of processing the difficult concept. Now, researchers from Melbourne’s RMIT University and France’s Université de Toulouse assert that honeybees, which like all insects are considered to be at the low end of the cognitive spectrum, also understand the abstract mathematical notion of nothing....

Vietnam’s Bà Nà Hills, which attracts over 2.7 million visitors annually, is home to many popular tourist attractions. These include the world’s longest non-stop single track cable car, a replica French medieval village complete with a faux castle, and the perfectly manicured Thien Thai gardens. However, none are as exquisite as the newly-built Cau Vang (Golden Bridge in Vietnamese) pedestrian bridge, which opened to the public in June 2018....

NASA’s ambitious mission to “touch” the Sun got underway at 3:31 a.m. EST on August 12 with the launch of the Parker Solar Probe from Cape Canaveral, Florida. Within six weeks, the spacecraft, which is currently traveling at 39,500 miles per hour, will conduct the first of seven flybys of Venus and use the planet’s gravitational pull to catapult itself closer to the Sun. The process, known as gravity assist, is instrumental in the probe’s mission to reach our fiery star....

While whales are known to grieve the loss of their loved ones, the recent story of an orca mom clinging to her dead calf for over two weeks demonstrates unprecedented evidence of the strength of the species’ familial bonds. The heart-wrenching saga began on July 24, 2018, after a female calf born to J35, aka Tahlequah — a member of the endangered Southern Residents Killer Whales (SRKW) pod — died 30 minutes after birth. Instead of letting the carcass sink into the ocean, the grieving mother began carrying the lifeless body by balancing it on her forehead or nudging it along the water surface with her nose....

Iron Man fans rejoice! The flight suit that transforms Tony Stark into a superhero is now a reality! Called Daedalus Mark 1, after the mythical Greek craftsman most famous for the feather wings he, and his son Icarus, used to escape from the kingdom of Crete, it is the brainchild of British inventor Richard Browning....

The most noticeable difference between the modern human face and that of the hunter-gatherers, who lived on Earth over 200,000 years ago, is the forehead. While we now have flat, smooth foreheads with visible eyebrows, our ancestors sported a pronounced brow ridge. Experts have always believed that the thick rim, and the evolution to the beautiful tufts of facial hair, served a physiological function. Now, a team of scientists from UK’s University of York and Portugal’s Universidade do Algarve suggest the distinct facial features help with our social relationships....

Researchers have always maintained that Triassic dinosaurs were small, chicken-sized critters, and that it was not until the Jurassic period — about 180-million years ago — that massive herbivorous sauropods, like the Diplodocus and Brachiosaurus, emerged. However, the discovery of a new dinosaur species in Argentina suggests that the animals achieved gigantism during the late Triassic period, about 30 million years earlier than previously believed....

Large predators are increasingly appearing in unexpected places — alligators in saltwater marshes, killer whales in rivers, and mountain lions far away from the closest mountain. Experts hypothesize that as successful conservation efforts increase the local populations of these predators, they are moving beyond their usual habitats in search of food. However, Brian Silliman, professor of marine conservation biology at Duke University has a different theory. He believes the animals are recolonizing habitats they lived and hunted in for centuries — before human activity pushed them to the brink of extinction, and long before researchers began studying them....
