The sound of the elephants

ElephantThe elephants’ sound is much like singing, not purring, when they rumble at friends and foes. This sound is heard for many kilometers away. Though humans can’t hear it, their infrasonic elements are very much alike to a cat’s purring. Scientists measured the sound of a dead elephant and they figured out that it might be bigger, similar to someone singing or speaking.

Cats are purring when their muscles contract very quickly. There were speculations that some of the elephant’s muscles, when contracted, give birth to a a very low infrasound. One scientist from the University of Vienna, Christian Herbst, said that an elephant could make these kind of rumbles, just exhaling air. His conclusion is that the purring premise is not quite true. He tries to study the lowest song of the elephants on the 3rd of August for the interest of science. Continue Reading

Spider studies

Adanson jumping spider

Jumping spiders falls under the category of invertebrates. For many years scientist was really amazed as how spiders manage a sophisticated nervous system with their hunting behavior. A detailed research was done on Adanson
jumping spiders who fall in the category of eight eyed spiders. Four eyes are present of the face of the spider and have the sharpest vision. The jumping spiders have four distinct layers of light sensitive at the back of the eyes but the uses of these four light sensitive tissues had not been found so far. It is found that if any object falls on the base layer that object cannot be seen on the next layer up and the object becomes blurrier. Continue Reading

Why Dolphins Wear Sponges?

It may be one of the strangest things you’ve ever seen: a dolphin swimming through the waters of the ocean with a sponge fitted over its beak. What in the world? The intelligent marine dwellers have found a way to protect their faces as they scour the rocks and broken coral for food stuffs. Rather than tearing the skin on the beaks and faces, they have devised this ingenious tool to be able to safely forage.

Researchers had thought, at first, that it would simply make more sense for the dolphins to feed from the mid-waters rather than along the bottom of the sea. In fact, the fish and crustaceans that inhabit the bottom of the ocean are more nutritious for the Shark Bay dolphins. The dolphins must have known this all along; developing a method of hunting safely instead of turning to other food sources that provide a less sound diet.

After studying the behavior of these dolphins, researchers found that hunting with sponges is an activity primarily carried out by the female of the species. It is thought that this is because of the pressures faced by a mother who has to rear her young for almost 5 years at a time. As the young swim and forage with their mother, they learn the interesting sponging technique which they, then, pass onto their young.

Sponge fishing works as such: a Shark Bay dolphin will fit a sponge onto its beak and scrape it along the bottom of the ocean. A fish will scare up from the bottom, the dolphin drops its sponge, heads to the surface for a breath of air and then dives down for its meal. The emerging fish will swim for several meters before it attempts to rebury itself, giving the dolphin the time it needs to drop, breathe and dive. A study conducted by Eric Patterson, a graduate student at Georgetown University, showed that by sponging, a dolphin can scare up a prey fish about every 9 minutes, making hunting in this manner extremely rewarding.

Many teens use the computer purchased specifically for schoolwork to play computer games or chat with friends. Monitoring software can not only record activities on the computer, but smartphone software such as Mobile Spy can silently record the teen's GPS information, text messages and phone call information.

Monitoring software sits silently on a computer or mobile device and monitors all of the activities carried out on the device, encouraging the teen to consistently use the device for communication. Activity is usually uploaded to an online account so that the parent can monitor activity from anywhere without having to get close to the phone. This is crucial since parents will usually not have physical access to the phone without arousing suspicion.

Many monitoring programs also come with keystroke loggers, which log keys recorded on the computer, a contextual blocker, and features that allow parents to block certain websites. All of these features allow parents to have a peace of mind when allowing their teens to use the Internet.
