This result is sometimes called ASC-US, which means atypical squamous cells of undetermined significance. The cells didnвt look quite like normal cells, but they couldnвt really be classified as abnormal. Normal cervical cells are present in about of women with inconclusive results. In some cases, a poor sample can lead to inconclusive results. That might happen if you recently had

The area referred to as the Bermuda Triangle, or DevilБs Triangle, covers about 500,000 square miles of ocean off the southeastern tip of. When sailed through the area on his first voyage to the New World, he reported that a great flame of fire (probably a meteor) crashed into the sea one night and that a strange light appeared in the distance a few weeks later. He also wrote about erratic compass readings, perhaps because at that time a sliver of the Bermuda Triangle was one of the few places on Earth where true north and magnetic north lined up. Did You Know? After gaining widespread fame as the first person to sail solo around the globe, Joshua Slocum disappeared on a 1909 voyage from MarthaБs Vineyard to South America. Though itБs unclear exactly what happened, many sources later

why do we need to drink a lot of water

What do you, the trees, and a hamster have in common? Give up? You all need water. All living things must have water to survive, whether they get it from a water fountain, a rain cloud, or a little bottle attached to the side of a hamster cage. Without water, your body would stop working properly. Water makes up more than half of your body weight, and a person can't survive for more than a few days without it. Why? Your body has lots of important jobs and it needs water to do many of them. For instance, your, which contains a lot of water, carries oxygen to all the cells of your body. Without oxygen, those tiny cells would die and your body would stop working. Water is also in lymph (say: limf), a fluid that is part of your, which helps you fight off illness. You need water to digest your

why do sweet things hurt my teeth

For many people, shopping for a large meal is a weekly tradition, the centerpiece of a holiday gathering or even a reward after a strenuous workout.

This sensation can indicate several factors, one of which often leaves people wondering: Are my teeth sensitive to sugar? Have a look at what tooth sensitivity is and some of its symptoms: is a simple term for root or dentin hypersensitivity. Periodontal disease and receding gums are two of the main culprits responsible for sensitive teeth: When the dentin on the root of a tooth becomes exposed, it has lost its protective enamel coating. Unprotected dentin allows food, plaque and acids to access and

 why do the hawaiian islands form a chain of volcanoes

why do the hawaiian islands form a chain of volcanoes

Scientists don t know all the details, but the process begins millions of years ago deep below the Pacific Ocean where the current islands are anchored to one of the rocky slabs that make up Earth s outer crust. This slab creeps over a hot spot, or a fixed plume of heat below Earth s surface that reaches a searing 2,500 F (1,400 C). Like a blowtorch, the heat transforms deep rocks into oozy magma. The magma rises upward until it erupts onto the seafloor. When the sizzling lava (which is what magma is called when it erupts) hits the cooler water, it hardens into an underwater volcano. Over time and the volcano packs on enough hardened lava to pop above the surface, forming an island. ...

 why do we have to pay taxes to the government

why do we have to pay taxes to the government

Why do citizens have to pay taxes? Taxes are collected from citizens by the government to accomplish a series of objectives, namely: To correct externalities: taxes are collected on goods or services where the social cost is not reflected in the private cost. For example, tobacco is heavily taxed due to the health problems it causes and because the cost associated with health care is usually borne by the government. Should this be the case, production is not a social benefit. To provide public services: taxes are collected for expenditures that would be less efficient should they be provided privately (defense and other partially public expenditures such as health and education). ...

 why do stars twinkle at night wikipedia

why do stars twinkle at night wikipedia

The twinkling of stars in our night sky is down to the EarthБs atmosphere. As light from the stars travels towards Earth it can easily move in a straight line, but once it starts travelling through the EarthБs atmosphere it gets bounced around in different directions by the particles in the air. For astronomers this twinkling can be a huge problem, especially when theyБre trying to accurately image a particular star. The more the star twinkles, the blurrier the image will be. If telescopes are launched into space then all images can be taken without EarthБs atmosphere in the way, but this is expensive. It is possible to use a system called Бadaptive opticsБ, when tiny motors alter the surface of the telescopeБs mirror to correct for this blur caused by the air. Answered by Megan Whewell,

 why does pepto bismol turn my tongue black

why does pepto bismol turn my tongue black

Answer 1: Has his happened to you? Someone you know? Kind of creepy, huh? It turns out that the active ingredient in Pepto-Bismol (bismuth subsalicylate) contains a chemical called bismuth. When a small amount of bismuth combines with trace amounts of sulfur, a black-colored substance (bismuth sulfide) is formed. Your saliva (and also your intestinal tract) can contain trace amounts of sulfur depending on what you have been eating and your individual metabolism, so this is why the black color can form on your tongue (and also in your bowels) - a chemical reaction has occurred! This discoloration is harmless, and it is always temporary. ...

 why do the spongy lungs appear collapsed

why do the spongy lungs appear collapsed

  The lungs are surrounded by a double layered membrane called the pleural membrane. The outermost layer (the parietal layer) is held close to the inner layer (the visceral layer) by a vacuum in the pleural cavity filled with a liquid to decrease friction as the two layers move during respiration. When one of the membranes are punctured (such as by a broken rib) air enters the pleural cavity (called a pneumothorax) and the tension between the two membranes is lost. ...
