  What Are Antibodies? Antibodies (also called immunoglobulins) are specialized proteins that travel thorough the blood stream and are found in bodily fluids. They are utilized by the immune system to identify and defend against foreign intruders to the body. These foreign intruders, or antigens, include any substance or organism that evokes an immune response. Bacteria, viruses, pollen, and incompatible blood cell types are examples of antigens that cause immune responses. Antibodies recognize specific antigens by identifying certain areas on the surface of the antigen known as antigenic determinants. Once the specific antigenic determinant is recognized, the antibody will bind to the determinant. The antigen is tagged as an intruder and labeled for destruction by other immune cells. Antibodies protect against substances prior to cell infection. Antibody Production Antibodies are produced by a type of wh...

  Life in zero gravity is much different than life on Earth.  We   get to enjoy both the taste and the smell of drinking hot coffee from a mug. Astronauts on the International Space Station don’t have this luxury and must drink their coffee using a straw that draws the liquid out of a closed container. This diminished coffee experience may change for the astronauts thanks to a new 3D-printedcup designed to help NASA study the behavior of fluids in micro-gravity. The idea for studying coffee and other liquids consumed in space surfaced after Italian European Space Agency astronaut Samantha Cristoforetti received an espresso machine. The opportunity to study capillary flow, liquid containment, and low-gravity fluid dynamics was too great to pass up. A team of researchers was assembled by NASA, and they went to work designing six different transparent polymer cups for use on the space station.  Five of the cups hold 150ml, while the sixth, a sma...

  Having a high cholesterol level increases your risk of cardiovascular disease, including heart disease and heart attacks. Making lifestyle changes such as increasing physical activity and losing weight can help lower   your  cholesterol.  Besides you might be able to boost the cholesterol-lowering ability of your diet even more. Research studies indicate certain foods contain natural compounds that can reduce cholesterol, usually by lowering the LDL (the ‘bad’ cholesterol) levels in your blood stream. Oats Eating a diet rich in whole grains is associated with having healthier cholesterol levels. Oats contain a soluble fiber called beta-glucagon. If you currently have high cholesterol levels, oats can lower cholesterol by as much as 20 percent. Oats and oatmeal are also an excellent source of minerals and protein. Walnuts. Walnuts are rich in both monounsaturated and omega-3 fatty acids. Eating these nuts may be able to r...

  Nuts are a delicious part of an anti-aging diet, helping you ward off chronic diseases like cardiovascular disease, diabetes, and certain cancers—and thanks to a review of two large-scale, long-term studies published in the New England Journal of Medicine in 2013, there's strong evidence that nuts of all kinds can help you live longer, too. In that research, eating just an ounce of nuts daily was linked to a 20 percent lower risk of death over a 30-year period. Nuts and General Health   Nuts have been a regular component of the human diet for thousands of years. A growing body of evidence that nuts are healthy prompted the U.S. Food and Drug Administration (FDA) in 2003 to issue a qualified health claim saying that current scientific data suggest that eating 1.5 oz (42g) of nuts each day may reduce the risk of heart disease. More recent research has shown that eating nuts is linked to a lower risk of colon cancer, gallbladder disease, and ...

    Pinterest is an American image sharing and social media service designed to enable saving and discovery of information on the World Wide Web using images and, on a smaller scale, GIFs and videos, in the form of pinboards.   Pinterest is a highly visual virtual pin board site that lets you "pin" or collect images from the Web. You create boards to help you categorize your images and add descriptions to remind you why you bookmarked them in the first place.   How Pinterest works is it lets its users post or “pin” original visuals, and as well as bookmark or “pin” them from across the Internet. These pins make up a theme-based virtual photo album or gallery known as a “board”. When a user saves a visual (image or video) to their Pinterest account, it becomes a Pin.   Pinterest is free to use for both individual people and businesses. A business account, which includes special promotion and analytics functions, is free as we...
