Usain Bolt was ramping into warp speed when suddenly, stunningly, the sprint turned into a somersault. Fifteen steps into the final homestretch of his final race, something gave in his left hamstring. The World鈥檚 Fastest Man skittered to a stop 鈥� hopping, skipping, jumping, then finally dropping to the ground and tumbling forward before coming to a rest 鈥�. He was certainly every bit as stunned as any of the 60,000-plus who packed the stadium Saturday, or the millions watching one of the world鈥檚 most entertaining showmen make his final curtain call in the 4×100-meter relay at world championships.

In a statement, Goodall鈥檚 family said they were extremely grateful to all those who were involved in the rescue. 鈥業t was with a heavy heart Susie left DHL Starlight to fend for herself, before she fills with water and rests on the Pacific Ocean floor.

More than 160 million years ago, the forests of ancient China were home to a bizarre predator: a聽tiny dinosaur that glided from tree to tree with leathery, bat-like wings. The newfound fossil, unveiled today in the journal聽Nature, is just the second feathered dinosaur found with signs of large membranes on its wings ….鈥淭he most exciting thing, for me, is that it shows that some dinosaurs evolved very different structures to become volant,鈥� or capable of some form of flight, says lead study author聽Min Wang, a paleontologist at China’s聽Institute of Vertebrate Paleontology and Paleoanthropology.

Bats get a bad rap. From horror films to tabloid pages to Halloween, media and cultural depictions of our planet鈥檚 only volant, or flying, mammals have long generated and reinforced unfounded fear …. Such hostile attitudes make it harder to conserve bats and thereby safeguard the many critical benefits they provide us. What鈥檚 more, persecuting bats because of the diseases they harbor could easily backfire.

It can be hard to tell the difference, in the midst of a crisis, between normal levels of angst and those that indicate we might be edging into serious psychological problems. Key signs of declining mental health include changes in appetite or sleep patterns that last more than a week …. Having more trouble concentrating than usual or being unable to enjoy things you used to enjoy may also indicate that your mental health is declining and that you need to try new coping strategies.

My motherly intuition senses that my baby is an old soul, recalling many past lives and really feeling them. According to her doctor, she鈥檚 teething and has gas. This may be true on a basic level, but I am certain that she鈥檚 also a highly advanced nascent human with acute existential angst. I鈥檝e lived long enough to know flatulence from the unbearable dread of existence.
