The brown recluse spider exists in significant populations mainly in the central Midwestern states southward to the Gulf of Mexico, especially in Oklahoma, Arkansas and Missouri.
SIZE
Body – 1/4 to 1 inch. The legs span an area roughly the size of a quarter to a half-dollar.
COLOR
Light brown to a dark, reddish or chocolate brown, but most are light to medium brown.
HABITAT
Houses are the common habitat of this kind of spider. Inside homes, the brown recluse spider can be found in any of the following places: dark spots within baths, dormitories, garages, closets and cellars, vent and heating conducts, seldom used clothes or shoes. They can nest in stored clothes, old books, boxes, furniture, toys, carpets, coatings, corners and cracks.
POISON
The spider has a powerful poison and occasionally bites a person, thus causing local injuries and sometimes more common symptoms. The poison causes the necrosis of the soft tissue that starts as a local inflammation with reddening, edemas and pain.

New research being presented at an obesity conference this week found that the cereals that are most frequently and aggressively marketed directly to American children as young as 2 were also the least healthy.
The study, reported in The Cereal Food Advertising to Children and Teens Score Report, was part funded by the Robert Wood Johnson Foundation, and was conducted by researchers from Yale University’s Rudd Center for Food Policy and Obesity. It is being presented at Obesity 2009, the 27th annual scientific meeting of The Obesity Society, in Washington on 27 October.
Researchers find that cereals for children have 85% more sugar, 65% less fiber and 60% more sodium than cereals marketed to adults. In addition, companies are spending more than $156 million a year to market these cereals directly to kids.

Many of colored contact lenses are available with and without vision correction so even people without a need for vision correction can wear them, as well as people who have astigmatism, or need bifocal contact lenses. The center of the lens, the part that lies over your pupil, is clear so you can see.
An enhancement tint is a solid but translucent (see-through) tint. An enhancement tint changes your eye color. As the name implies, it’s meant to enhance the existing color of your eyes. These types of tints are usually best for people who have light colored eyes and want to make their eye color more intense. Color tints are deeper, opaque tints that can change your eye color completely. Usually they are made of patterns of solid colors. If you have dark eyes, you’ll need this type of color contact lens to change your eye color. Color contacts come in a wide variety of colors, including green, amethyst, blue, gray, violet, and hazel.

A new study found that many contact lens wearers in the United States do not follow the recommended replacement schedules for their lenses, making them vulnerable to a variety of eye infections, which cause serious eye problems.
The study examined 1,654 contact lens wearers in groups with different replacement frequency. It found that people wore their contact lenses for a much longer period of time than recommended and didn’t replace contact lens case in time:
- 26 % of those who over-wore their lenses said they wanted “to save money” by wearing their contacts for longer periods
- 51 % said they “forgot which day to replace their contact lenses”
- 18 % of participants reported it was “not important” to clean contact lenses every day
- 16 % of contact lenses wearers replaced their contact lens case only once a year
- 14 % never replaced their lens case

What is a blood test?
Blood tests are a very useful diagnostic tool. Blood is made up of several different kinds of cells and other compounds, including various salts and certain proteins. When blood clots outside the body, the blood cells and some of the proteins become solid. The remaining liquid is called serum, which can be used in chemical tests and in tests to find out how the immune system fights diseases.
What do doctors examine in the blood?
Blood contains two main elements: the fluid that is called plasma and cells. There are three kinds of cells: red blood cells, white blood cells and platelets. To get the information they need from the blood, doctors actually do several tests with the blood sample. These include measurements of the levels of the cells and a blood smear. A blood smear is a film of blood placed on a slide to allow doctors to look at the individual cells under a microscope.

C-reactive protein (CRP) is a protein produced by the liver when there is inflammation somewhere in the body. People with high levels of CRP may be at higher risk for an acute coronary event (heart attack) and death but not stroke, according to a study published in the October 20, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.
According to the scientists, testing for this protein – which is released into the bloodstream when the blood vessels leading to the heart are damaged – adds to the predictive value of screening blood samples for both total and HDL (good) cholesterol levels. Thus C-reactive protein testing may improve doctors’ ability to predict heart disease risk.

cancer cell
Modern cancer treatments like radiation and chemotherapy have proven remarkably effective at treating many cancers, especially in combination, but are plagued with toxic side effects. These treatments kill healthy cells as well as cancerous ones. Nanotechnology offers the means to aim therapies directly and selectively at cancerous cells.
Chemotherapy employs drugs that are known to kill cancer cells effectively. But these drugs kill healthy cells in addition to tumor cells, leading to adverse side effects such as hair-loss, nausea, neuropathy, fatigue, and compromised immune function.

Nanotechnology has reached critical mass. Nowhere is this more evident than in medicine. Rising medical costs, demands for less-invasive procedures and pressures for immediate feedback of medical conditions, all point to nanotechnology as offering a new approach in healthcare.
When a person suffers from eye ailments today, nine times out of ten, he will be prescribed eye drops to treat his illness or relieve his discomfort. However, 95 percent of the medication administered in this manner flows to where it is not needed. Most eye medications are delivered by drops. The drops usually mix with tears and drain into the nasal cavity, where they can flow through the blood stream to other organs and cause serious side effects. In addition, dosage through eye drops is inconsistent and difficult to regulate, as most of the drugs are released in an initial burst of concentration.
To counter these problems, researchers have been studying the use of contact lenses to deliver eye medication.

Nanotechnology is the creation of functional materials, devices and systems. Nanotechnology makes use of minuscule objects – whose width can be 10,000 times narrower than a human hair – known as nanoparticles. A scientific and technical revolution has just begun based upon the ability to systematically organize and manipulate matter at nanoscale.
An atom has a diameter of about 0.1 nm. An atom’s nucleus is much smaller – about 0.00001 nm. Atoms are the building blocks for all matter in our universe. You and everything around you are made of atoms. Nature has perfected the science of manufacturing matter molecularly. For instance, our bodies are assembled in a specific manner from millions of living cells. Cells are nature’s nanomachines. At the atomic scale, elements are at their most basic level. On the nanoscale, we can potentially put these atoms together to make almost anything.
You might be surprised to find out how many products on the market are already benefiting from nanotechnology. Upwards of 600 products on store shelves today contain them, including transparent sunscreen, lipsticks, anti-aging creams etc.
