The pesky knots magically appear to come apart at the most inconvenient times – in the final sprint of a long run or, just before a crucial point in a game. However, while there has been a lot of research conducted on the durability of the various types of knots, nobody has ever investigated the fundamental question – why do laces come undone? Now, thanks to a team of researchers at the University of California, Berkeley, there is finally a scientific explanation to this knotty problem which affects both young and old....

At the beginning of each school year, students rush to their new classrooms to see what exciting surprise is in store for them. Some are greeted with a new class pet, while others encounter a reading nook furnished with comfortable bean bags or couches. This year, Oregon educator Kyle Hubler took the first-day thrill to a whole new level by transforming his classroom into a mini Hogwarts, complete with wands, (fake) owls and costumes!...

Shortly after, at about 8:02 a.m ET, the star spewed out a bigger, and more spectacular, X9.3 flare — the most powerful on record since December 2006....

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....

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....

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.
