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....

Over a 100 million years ago, an 18-foot (5.48 meter) long, 2,500-pound (1,133 kg) pineapple-shaped dinosaur met an untimely death when it was swept away by a river in what is now Alberta, Canada. Fortunately for us, its body ended up situated back-first on the muddy floor of an old seaway. This helped preserve the ancient behemoth’s front half in such extraordinary 3-D detail that the armored dinosaur almost looks alive....

Innovations like 3-D printing have enabled scientists to make significant progress in manufacturing various bioengineered organs and tissues. However, the one organ that has been hard to replicate is the human heart. That’s because current technology is unable to replicate the network of tiny blood vessels that transport oxygen inside a tissue as dense as the human heart muscle....

Hurricane 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!...

Utrecht, 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....

On Monday, August 21, millions of Americans across the country donned their protective eyeglasses to watch the highly anticipated total solar eclipse. Though the eclipses, which occur about every 18 months, are not rare, this one was historic. It was not only the first total solar eclipse visible from the mainland U.S. in more than 38 years, but also the first to be seen coast to coast in almost a century....

Parents 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....

Governments, corporations, and even individuals concerned about losing valuable data or photos in the event of a cataclysmic disaster can now rest easy thanks to the recently opened Arctic World Archive. Located 300-meters (984-feet) below the ground inside an abandoned coal mine in Svalbard, a Norwegian archipelago between mainland Norway and the North Pole, the “Doomsday Vault” is equipped to keep information safe in the event of a natural or man-made catastrophe....

While Japan is known to have higher than average rates of stomach cancer, the residents of the town of Kaneyama in Yamagata Prefecture appear to be particularly susceptible to the gastric ailment. After a recent report revealed that the municipality had one of the highest stomach cancer fatality rates out of the nation’s 344 “secondary medical districts”, the town officials decided to get its 6,000 residents tested....
