Scientists have long known that the world’s first flower bloomed between 250 million and 140 million years ago, during the Cretaceous period when dinosaurs dominated the earth. The single mutation was so successful that flowering plants, or Angiosperms, now make up almost 90% of all plant species, far outnumbering seed plants like conifers, that appeared on earth much earlier, between 350 million and 310 million years ago.
اقرأ المقالFans of fidget spinners, 2017’s must-have toy, spend copious amounts of time spinning the three-pronged device with a flick of their finger. That’s because the addictive toys can rotate on their own, for only a few minutes at the most. However, if a Japanese company has its way, users will be able to relax and watch the gadget whirl for over 12 minutes with just one flick.
اقرأ المقالMost toys are fads that last a few years, or even months, before they get replaced by the next craze. However, the Slinky – the pre-compressed coil of wire, or plastic, which can “walk” on its own – has been entertaining children and nostalgic adults for over 70 years! It is therefore not surprising to hear that every August 30, fans across the U.S. celebrate this iconic toy with a National Slinky Day!
اقرأ المقالEarlier this month, millions of Americans were treated to a rare spectacle: a total solar eclipse that was visible from coast-to-coast. While Florence, a massive asteroid that will zip past our planet on September 1, will not overshadow the stunning event, it will make history of its own. According to Paul Chodas at the Center for Near Earth Object (NEO) Studies, the space rock is the largest to pass this close to our planet since the first near-Earth asteroid was discovered over a century ago.
اقرأ المقالHurricane Harvey, which began as a tropical depression in the Gulf of Mexico on Wednesday, August 23, rapidly escalated to a Category 4 storm as it made its way towards Southern Texas. As expected the powerful hurricane, which packed 130mph winds, made landfall near the city of Rockport on August 25 at about 10:00 pm local time, causing widespread destruction. Three hours later, it made a second landfall on the northeastern shore of Copano Bay, this time as a Category 3 storm with 125 mph winds!
اقرأ المقالUtrecht, the fourth largest city in the Netherlands, is a cyclist’s dream. Unlike other urban areas that confine riders to tiny lanes, cyclists here get priority with dedicated “bicycle streets,” where cars are considered “guests,” as well as special bike tunnels and bridges. The city is also in the process of constructing the world’s biggest indoor parking lot for bikes at its central train station. However, the over 60 percent residents who use the two-wheelers as their primary mode of transportation are still frustrated because, like cyclists all over the world, they have to make constant stops at traffic lights.
اقرأ المقالYou might not think of plants as particularly chatty but in reality, they communicate surprisingly well with each other, especially when faced with danger. According to a recent study in the journal Frontiers in Plant Science injured plants send out emergency signals to alert neighbors to start building up their defenses.
اقرأ المقالParents often use the expression “in the blink of an eye” to express their astonishment at how fast their children reach adulthood. However, for those with newborns, the phrase is literal given that an average baby grows between 6 to 7 sizes within the first two years! While exciting, the constant wardrobe replenishment is expensive and also results in a lot of wasted clothing. To tackle the issue, Ryan Yasin has created an origami-inspired line of clothing that expands (or contracts) automatically, resulting in a perfect fit each time.
اقرأ المقالA massive patch or “blob” of warm water experienced along the usually cool U.S. Pacific coast from 2013 to 2016 wreaked havoc on the marine ecosystem. Fishermen in Alaska reported seeing warm water sharks, while California beachgoers encountered tropical poisonous water snakes. Though the return of cooler temperatures in 2017 rid the area of most unwanted visitors, bioluminescent pyrosomes ((Pyrosoma atlanticum) have decided to stay and are now washing up along the coast in unprecedented numbers.
اقرأ المقالWhen Michael Phelps announced his retirement at the 2016 Rio Olympics he really had no intention of swimming competitively again. However, that changed when the decorated athlete was approached by the Discovery Channel to help kick off shark week with a race against one of the world’s fastest and most efficient predators — a great white!
اقرأ المقالWith its majestic mountains, spectacular landscapes, and pristine beaches, Ireland’s Achill Island has always been a popular European tourist destination. However, since April, the rugged 57-square mile island of just 2,600 residents has gained worldwide fame thanks to the ‘miraculous’ return of a beach that was washed away over three decades ago.
اقرأ المقالSometime between July 10 and 12, a massive iceberg the size of the US state of Delaware broke free from Antarctica’s Larsen C Ice Shelf. The crack that led to the separation was visible in the first images of the ice shelf captured by NASA satellites in 1963. However, the rift remained dormant for decades, before suddenly spreading northwards and widening by 18 miles between 2011 and 2015 and then an additional 13 miles in 2016. As of last month, the iceberg, named A-68 by the US National Ice Center, was hanging by a thread and experts knew it was just a matter of time before it broke free.
اقرأ المقالPods of crafty orcas in Alaska’s Bering Sea have figured out an easy way to get fed. Instead of seeking out the fish themselves, the clever whales chase down fishing boats and steal the entire day’s catch, as much as 20,000 to 30,000 pounds of halibut and black cod, in a single swoop.
اقرأ المقالSommeliers are usually defined as wine experts that recommend meal pairings at restaurants. Not Martin Riese. He is America’s first and only sommelier who helps patrons select the best water to go with their choice of food. The 41-year-old discovered his unique skill of being able to distinguish the subtle differences in the taste of waters from different regions at a young age while touring Europe with his family.
اقرأ المقالHenderson Island in the south Pacific Ocean has always been known for its remarkable biological diversity and untouched ecology. Now, the remote UNESCO World Heritage site that lies 3,100 miles (5,000 km) from the closest human settlement, can also lay claim to being one of the most polluted places on Earth.
اقرأ المقالThough most of you probably are well into your summer break, the astronomical season does not begin until June 20. Called summer solstice, it is the day when the North Pole is most inclined towards the sun, allowing residents of the Northern Hemisphere, to enjoy the longest day (and shortest night) of the year. Of course, the opposite is true for the Southern Hemisphere where residents will celebrate winter solstice and experience the shortest day (and longest night) of the year.
اقرأ المقالEvery ocean lover knows the perils of getting caught in a rip current. Experienced swimmers know it is relatively easy to escape the narrow channel of fast moving water by floating and allowing it to drag you further into the ocean or by swimming alongside the shore. However, novice beachgoers often panic, and try to swim to land, placing themselves at risk of drowning due to fatigue. According to the US National Ocean Service, the currents kill about 100 Americans each year and account for 80% of all lifeguard rescues. These scary statistics may soon be a thing of the past, thanks to Clever GIRL (Global Intelligent Rip Locator), a smart buoy that alerts swimmers of the presence of deadly rip currents.
اقرأ المقالSome fortunate visitors to the Chicago Botanic Garden recently witnessed the rare opening of not one, but two, titan arums. Better known as corpse flowers due to their pungent odor that resembles decaying flesh, the massive plants bloom once every ten years, and that too, for only a few hours. However, that may be a good thing given that when the petals unfurl, the stench emanated is so foul that it has earned the titan arum the title of the “world's smelliest flower.”
اقرأ المقالEvery winter, hundreds of humpback whales migrate long distances from their high latitude feeding grounds in the Arctic and Antarctic to warmer tropical regions to breed and give birth. The newborn calves, which consume over 52 gallons of milk on a daily basis, have only a few months to pack on the body fat needed to survive the long trek back to cooler waters in summer. How the babies signal hunger and avoid predators during these formative months has always been a mystery to scientists.
اقرأ المقالThe city-state of Dubai that is home to the world’s tallest building, manmade islands shaped like palm trees, drone taxis, and jetpack wielding firefighters, is fast cementing its reputation as the city of the future. On May 22, Dubai officials added to their list of futuristic accomplishments with the introduction of the world’s first operational robot police officer.
اقرأ المقالHousing ranks high among the numerous challenges that still need to be overcome before humans can colonize Mars. The brave pioneers that make the six-month voyage to the Red Planet will need a place to reside as soon as they land. While the optimal solution would be to have the structures ready before they get there, it has thus far been a challenge given that most automated construction robots have never made it out of the laboratory. Now, there may be a glimmer of hope thanks to Massachusetts Institute of Technology’s (MIT) newly unveiled Digital Construction Platform (DCP).
اقرأ المقالGiven that Americans consume over 100 million donuts each year, they don’t really need an excuse to devour the gooey fried treat. However, if you are among the minority that does, you are in luck, because Friday, June 2, is National Donut Day. Celebrated annually on the first Friday of the month, the holiday’s origin can be traced back to Salvation Army workers who volunteered to help injured US troops during World War I (WWI).
اقرأ المقالJapan’s newly unveiled Train Suite Shiki-shima that travels at a leisurely pace of 110 kph (68 mph) is a bit of an anomaly in a country known for magnetic levitation bullet trains that can traverse at speeds of up to 603 kph (375 mph). However, the purpose of the luxury sleeper train, which accommodates just 34 guests, is not to get passengers to their destination rapidly but to allow them to the enjoy the country’s beautiful landscapes while being thoroughly spoiled.
اقرأ المقالWith technology permeating almost every aspect of our lives, the demand for computer programmers can only increase.
