questions@ideasanddiscoveries.com www.facebook.com/ideasanddiscoveries KEEPING ART IN GOOD SHAPE I want to share my appreciation of an article in the science section of your magazine, “How Do You Earthquake-proof an Icon of Art History?” in the May issue. I have always been fascinated by the great works of the Renaissance period—Leonardo, Michelangelo, and many others. When I read this article, I felt a sense of admiration for all those professionals who have the task of preserving the cultural wonders of our planet. I wish all of them many successes, and I know that thanks to their painstaking restoration work and perseverance in obtaining funds to carry out this hard work, our future generations will continue to admire these works. I don’t know at this time if even the restorers will be able to continue…

…this my first flying lesson, and my instructor has passed out!

Max Sylvester is now almost an hour into his flight and flying at about 6,200 feet. The student pilot’s heart is no longer pounding and he can feel the tension in his muscles relax as he looks down on the gleaming Indian Ocean off the coast of Perth in Western Australia. The single engine of the Cessna 152 is throbbing peacefully. Fascinated by the incredible view, the 29-year-old pilot is finally beginning to enjoy his flying lesson when he feels a dull blow to his shoulder. As he turns, he sees it’s the head of his instructor, Robert Mollard, who has just passed out cold with no warning. Suddenly Sylvester’s heart is pounding far more than before as the adrenaline floods his system. He shakes Mollard’s body but gets no…

the secret life of bats

As the last rays of sunlight illuminate the majestic sandstone formations throughout Brazil’s Catimbau National Park, the treetops have already been shrouded in the darkness of night. “They’re coming.” You can hear the word being passed on from house to house. The area’s inhabitants gather up their belongings and seek safety in their homes. The creatures they are fleeing from approach soundlessly to human ears, calling out to one another at frequencies above the range of our hearing. Deprived of their usual fare, they are on the hunt for human blood. Unlike the other two known species of vampire bat, Diphylla ecaudata had not been known to take any interest in human victims until fairly recently. The hairy-legged vampire bats were believed to feed exclusively on wild and domestic birds.…

the dark power of dreams

It was dark, and I was running in the rain across a deserted town square. The pavement was slippery, and I started feeling dizzy. Then I heard a loud cawing that was ear-splitting and terrifying. A big black bird was diving down at me out of a dark sky. I screamed and tried to duck, but the crow already had its claws in my hair. I fell to the ground and cried out in pain as the bird pecked wildly at my face, opening a wound in my head. I could feel hot blood running down my face—then I realized I was dead. It was at this moment I sat up in bed, trembling and gasping for breath.” This grim scene was the nightmare of a 27-year-old man. It is just…

a dictionary of dream symbols

A Dreaming about a gaping abyss This suggests an obstacle is generating anxiety and that you need to overcome it, which may be exemplified in the dream by how you deal with the chasm: flying over it, jumping across it, climbing down into it and back out again. Standing at the edge of an abyss and feeling baffled, paralyzed, or dizzy suggests fear, helplessness, and despair. Falling into an abyss symbolizes your hidden fear of failure or capitulation. If a path leads to the edge of an abyss and ends, this is a warning to the dreamer to stop and reconsider a decision. Dreaming about aggression Beating or shooting someone in a dream is an expression of repressed anger. If the dreamer is attacked or killed, however, it suggests that someone in the dreamer’s…

the science of stings

HOW DOES A STINGER GET UNDER YOUR SKIN? A bee’s stinger is about 1.5 millimeters long. It’s a modified version of the ovipositor (egg depositor) of other insects, therefore it isn’t present in males. The stinger consists of three hollow parts: the stylet and two barbed lancets. To sting, the bee inserts its stylet as perpendicular to the target surface as possible. It then uses the force of its legs and abdomen as well as the motion of the backward-facing raked barbs to achieve maximum penetration. During insertion the barbs on the lancets catch the skin at multiple points, creating a gap between the tips that exposes the central canal of the stinger, through which the venom will flow. HOW DOES THE VENOM GET INTO YOUR BODY? The bee’s venom is pumped into…
