questions@ideasanddiscoveries.com www.facebook.com/ideasanddiscoveries NEW PRESTIGE FOR OLD GLORY The last issue about the unsolved murders of history was great. I never knew there could be so many events hidden in history! Just a note: The picture of the flag on page 49 should be drooping, because there’s no atmosphere on the moon, and therefore no wind, resulting in a drooping flag. Rick Zhou, Bellevue, WA We’re glad the July issue’s feature story was enjoyable. The cases presented in the article are a sampling of history’s famous cold cases, and often the more one digs into a story, the more inconsistencies come to light. The information is out there but it is not generally publicized, and the standard version of events becomes accepted even though there is evidence of another story beneath the well-known one. With regard to…

a photo and its story

WHO’S THE TOP ROBOT? Combat between robots manned by humans is no longer the stuff of science fiction. An abandoned steel mill in Japan served as the battlefield when California-based MegaBots sent its 6-ton monster Iron Glory into a fight to the death against Kuratas, made by Japan’s Suidobashi. Iron Glory’s paintball cannon didn’t stand much chance against the 600-pound metal fist of Kuratas, which stands 13 feet tall and is slightly heavier than its opponent. Although Iron Glory’s cannon is able to shoot 3-pound paintballs at 100 miles per hour, the first shot shattered inside its firing chamber. So Kuratas seized the advantage, charging across the warehouse to strike Iron Glory and topple it on its back. The first round was over in 24 seconds. But MegaBots did not give…

the aerial genius of hummingbirds

Higher and higher, the Anna’s hummingbird rises into the air until it is no more than a tiny dot against the sky. Then suddenly—as if it had reached the peak of an invisible mountain—it comes streaming down from the sky in a death-defying nosedive. The tiny creature plummets at 50 miles per hour before emitting a loud chirp and halting spectacularly in midair. However the chirping sound does not originate in its throat. Instead it is produced by the tail feathers of this male as he spreads them at the bottom of his dive, using them like the reed of a clarinet to make his mating sound. And the little fellow is quite persistent: He repeats the breathtaking sequence of climb and nosedive several more times in the hope of…

smarter in 60 seconds hummingbirds

Did hummingbirds originate in Europe? While the range of hummingbirds today is restricted to North and South America, the oldest known hummingbird fossils—some 30 million years old—are found in Germany. Having been discovered by private collectors, the species was named Eurotrochilus inexpectatus to reflect the surprise that the find provoked. There is speculation that hummingbirds originated in Eurasia and used the former land bridge between Siberia and Alaska to get to the New World. Do hummingbirds eat meat? Hummingbirds get the quick energy they need to sustain their extremely high metabolic rate from nectar. But it doesn’t contain all the vitamins, minerals, proteins, fats, and amino acids that they require. To obtain these they consume small insects, such as beetles, gnats, ants, mosquitoes, aphids, and wasps. However their favorite food is spiders, which…

the deadliest beaches in the history of the world

In his lifetime, Admiral Horatio Nelson achieved almost godlike status as a military commander. Commemorated today for his victory at Trafalgar in 1805, he first became established as a British national hero when he defeated the Napoleonic fleet in the Battle of the Nile at Aboukir Bay in Egypt in 1798. Perhaps Central America would be home to a still-flourishing advanced civilization if Hernán Cortés had not chosen to land on a Mexican beach 500 years ago (page 18). This magazine might not exist if the Persians managed to conquer Greece in 490 BC (page 27). And it’s better not to speculate about the world we would be living in had the Allies not made their landing in Normandy in June 1944 and instead lost the war to Germany (page…

the beach where the third reich died

The beach of Colleville-sur-Mer is broad, flat, and lovely, but that’s not why people go there today. Most visitors are commemorating the horrific scenes that played out on the beaches of Normandy on the morning of June 6, 1944, when a fleet of almost 7,000 Allied vessels took position offshore. On that day—recognized in history as D-Day—156,000 Allied troops and paratroopers came ashore at Colleville-sur-Mer and four other D-Day beaches, 73,000 of them from the U.S. and 83,000 from the UK and Canada. Some of their worst fears were realized on those beaches, but they struck a powerful blow for the liberation of Europe from Hitler’s Germany. They only knew the beach at Colleville by its code name, “Omaha Beach,” and many of their names were to be written in…
