CAUGHT IN THE MIRROR of her parents' truck, 12th grader Amy "Dandilion" Olsen waits at a light in downtown Austin, Texas.
THE CONCERT WAS UNLIKE ANY Austin Brown (center) had attended—a dance party called Dayglow where blasts of fluorescent paint rained down on crowds in downtown Austin. CRACKING JOKES IS PART of the daily repartee between Deborah Kipp and her daughter, Anastassia.
Decisions, DecisionsCars and parties, first cigarettes and first dates, school demands and free time—teens encounter risks both large and small every day, and their choices can be puzzling at times.
ON THE RANCH OUTSIDE AUSTIN where he and his father planned a hunt, Spencer O'Loughlin watches fellow hunters clean and pose with a buck. In another instance of one animal riding on another, photos from California-based photographer Phoo Chan show a crow nestled on a flying eagle's back. When close enough to land, the crow was probably mid-attack, explains Kevin McGowan, a biologist who specializes in crow behavior at the Cornell lab of Ornithology. Birds are very territorial, particularly during the summer when their hatchlings are vulnerable. Chan's photos capture the entire sequence of events, suggesting the event actually happened, says Mallory Benedict, an assistant photo editor at National Geographic.

These little brown bats hybernating in a cave in West Virginia show signs of white-nose syndrome. A deadly disease called white-nose syndrome has killed some seven million of them since 2006, and it continues to spread today. The disease is named for the white fungus, or mold, that infects the skin on the nose, ears, and wings of hibernating bats.
He figured if the bacteria could prevent molds growing on bananas, it might be able to stop a mold growing on a bat. Scientists will continue testing the bacteria to make sure it wona€™t harm the bats or the cave ecosystem in which they hibernate. Tyrannosaurus rex arose during the Cretaceous period about 85 million years ago and thrived as a top land predator until the dinosaurs went extinct 20 million years later. Awaiting renovations, dinosaur models of differing scales crowd a warehouse at Dinamation headquarters in Irvine, California.
This rendering of Cretaceous life shows the diverse range of dinosaurs that lived between 145 and 65 million years ago, including maiasaurs (front left); tarbosaurs (top right), and pterosaurs (top center).

The chalk cliffs on Germany's Rugen Island rise 330 feet (100 meters) or more over the Baltic Sea.
This scanning electron microscope image reveals the intricate patterning of ancient coccolithophores, microscopic plankton abundant in shallow seas during the Cretaceous period. Pterosaurs, like these depicted gliding near an ancient sea, first arose during the Triassic period about 215 million years ago. This Sapeornis chaoyangensis fossil, housed in a Beijing museum, offers clues about the feeding habits of the Earth's early birds. Like their cousins the dinosaurs, pterosaurs stand out as one of evolution's great success stories. National Geographic explores how we can feed the growing population without overwhelming the planet in our food series.

As the global population soars toward nine billion by 2045, this corner of Africa shows what's at stake in the decades ahead. Think of it as an equation, says psychologist Laurence Steinberg, where consequences aren't given the weight they should be.
Taylor Dicristofalo (at right) said she probably wouldn't have had her tongue pierced if her best friend hadn't dragged her along on an "exciting and scary adventure" in downtown Austin. Teens may choose to hang out with peers, but structured interactions with parents and other adults are also crucial. Crows (and many birds) seem to have a Napoleon complexa€”the mere presence of a larger bird incites heckling and mobbing.

These experts have developed a treatment using bacteria thata€™s known to slow the ripening of fruits and vegetables. Bats with white-nose syndrome were captured from Missouri and Kentucky, sedated, and exposed to the bacteria.
So never mind calling Batmana€”thanks to some real-life superheroes, bats have a fighting chance.
This skeleton, on display in Chicago's Field Museum, is a cast of perhaps the world's most famous fossil: "Sue," a 67-million-year-old T.
The sequence, which used digital scans of an actual fossil skeleton, was part of a 2001 million-dollar project by the Smithsonian National Museum of Natural History to accurately remount its nearly 100-year-old Triceratops specimen. Some of these specimens would have seen their heyday during the Cretaceous period, including the familiar Tyrannosaurus and Triceratops, the Parasaurolophus (front right), and the flying pterosaur (top left). In the foreground are depicted the first flowering plants and one of the earliest mammal relatives, both of which developed during this period and went on to survive the dinosaur extinction at the end of the Cretaceous.
These ancient structures are made nearly entirely of the skeletons of calcite-covered plankton called coccolithophores, deposited by the trillions during the Cretaceous period.
Madagascar is awash in fossils from the Cretaceous period, when the island broke off from Africa and later split in two.

As these organisms died, their skeletons, called cocospheres, fell by the trillions to the seafloor, forming layer upon layer of calcium carbonate. They endured for 150 million years, colonizing every continent and evolving into more than 120 species. The presence of gastroliths—stones ingested by animals to grind food in the gut—indicates that this species was a plant-eater.
They first appeared during the Triassic period, 215 million years ago, and thrived for 150 million years before going extinct at the end of the Cretaceous period. At least one Friday a month, boys gathered after school in the backyard of Bryan Campbell (at far left) to wrestle and box. O'Loughlin returned empty-handed after four days of waiting quietly with a bow and arrow in a tiny camouflage tent. McGowan says territorial birds dona€™t normally get too close, but this particular crow probably found itself in the eagle's draft and settled in for the ride.

Other species act as pollinators and seed dispersers, helping forests that have been cleared or damaged to regrow.
It does this by stemming the release of gases from fruits and vegetables that tell them to start ripening. Others, like the stegosaurids (front center), were already extinct when the Cretaceous began. Millions of years of pressure and heat turned these layers into the chalk we use today in our everyday lives and helped preserved countless fossils from the Cretaceous. Other significant features include exceptionally long forelimbs, suggesting that Sapeornis, the largest known bird from the early Cretaceous, might have been able to soar. Uncontested in the air, pterosaurs colonized all continents and evolved a vast array of shapes and sizes.
The other moved northeast, eventually colliding with Asia and forming the Indian subcontinent. This specimen, found in Italy, is Eudimorphodon ranzii, with a wingspan of about three feet (one meter) and 114 tiny teeth packed into its jaws. Viewed through the eyes of evolution, their most exasperating traits may be the key to success as adults. The boys often used phones to film their contests, posting the videos to a private Facebook group so more friends could admire their prowess. Thereafter, check back for the full replay video and transcript text which be added as soon as available. The rush of a headlock, a bond between friends—their fights delivered both excitement and social rewards.
