Toxoplasmosis is an infection caused by a parasite. The parasite is called Toxo-plasma gondii. It can be found in cat f***s and under-cooked meat, especially venison, lamb and pork.. It can also be transmitted through contaminated water. Toxoplasmosis can be deadly or cause serious birth defects for a fetus if the mother becomes infected.

Most people who have toxoplasmosis never have any symptoms at all. According to the Centers for Disease Control and Prevention (CDC), over 60 million people in the United States are infected with the parasite. The people who are most at risk for serious infections are those with compromised immune systems and infants born to mothers with active infection during their pregnancy.

What makes self-cleaning concrete so amazing is that the cleaning happens without any scrubbing, thanks to the power of the sun. When light and heat strike the surface of the concrete, catalysts such as titanium oxides use the energy to break dirt into basic oxygen, water, carbon dioxide, nitrate and sulfate molecules. Those that take the form of gases float off the surface of the concrete. Liquid and solid pollutants are left behind to be washed away by rain. As the concrete cleans itself, it uses a similar process to purify the polluted air around it.
