Scientists have discovered what they believe is one of the biggest impact craters in the world near the Falklands Islands. They say the crater appears to date to between 270 and 250 million years ago, which, if confirmed, would link it to the world’s biggest mass extinction event, where 96 percent of life on Earth was wiped out.
If beans are, as is sometimes said, a musical fruit, avocados are produce’s Forrest Gump. Far from being just a simple superfood with a deceptively tough shell, avocados have popped up, persistently, throughout some of the notable political and cultural controversies of the last century, from the War on Fat to the War on Brunch to the looming Tariff War on Mexico. They even endured, in typical hardy fashion, the Great Pea Catastrophe of 2015, which began when the New York Times encouraged its readers to try adding peas to their guacamole. Guac fans the world over didn't just question the Times' taste. They exploded.
Barbara D. Livingston is one of America's most respected horseracing photographers, having photographed the sport she loves for more than 35 years. Livingston was just ten when, in 1971, she first aimed a camera toward the Thoroughbred world. Two years later, she photographed greatness as Secretariat whisked past in a Saratoga workout. By the next year, when she watched Ruffian dominate the 1974 Spinaway, she had decided upon her goal: to record racing history. Ruffian's Spinaway remains the most exciting race Livingston has ever seen. In a sport of raw speed where champions are determined by milliseconds, it's Barbara Livingston's job to freeze time.
The face of a modern human is almost uniquely flat and extraordinarily expressive. But our remarkable faces may not be as "modern" as we think. (A reconstruction of a Neanderthal face is illustrated above). These reconstructed faces look impassive, but a range of emotions are painted onto visitors' faces at the Natural History Museum in London.
