Male humpback whales are well-known for the long sweet melodies they sing during the breeding season. The soulful songs that last anywhere from ten to twenty minutes, are not random noises, but carefully orchestrated themes that keep repeating and developing. Scientists are not sure if the mammals sing to attract partners or to deter rivals but once they get going, they tend to repeat the same tune over and over, for long periods of time.

Just days after Hurricane Harvey struck Texas and parts of Louisiana, leaving behind unprecedented destruction, an even stronger tropical cyclone was reported heading towards Florida. Irma, the most powerful Atlantic Ocean hurricane in recorded history, first brought chaos to the Caribbean, devastating islands like Barbuda and St. Martin on September 6, where it struck with Category 5 winds that at times reached up to 185 mph.
Tony Stark, aka Ironman, constantly seen manipulating 3D holographic images and floating displays projected in mid-air from his phone or tablet. Unfortunately, the rest of us are not as fortunate because the current computer-generated holograms are too bulky to be integrated into our personal devices. However, if a team of researchers from Australia's RMIT University and the Beijing Institute of Technology (BIT) is right, we may all soon be able to mimic Ironman, at least, when it comes to playing with 3D holograms.

Before fame, the world's most celebrated writers had regular-kid problems. A young J. R. R. Tolkien was bitten by a huge tarantula—or as he called it, “a spider as big as a dragon.” Toddler Zora Neale Hurston took her first steps when a wild hog entered her house and started chasing her! Kid Authors tells their stories and more — the diverse and inclusive cast that includes Beverly Cleary, J. K. Rowling, Sherman Alexie, Stan Lee — through kid-friendly texts and full-color cartoon illustrations.
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.
Fans 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.
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.
Earlier 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.
