What is Hydroseeding? Hydroseeding is a method that can be used for planting grass for purposes of erosion control, or to grow new lawns entirely; it has been around since the 1950s. It is also an efficient, inexpensive alternative to laying sod in an area where grass or a lawn is desired. Hydroseeding can also be referred to as hydraulic mulch seeding, hydromulching, or hydroseeding. How does it work? The machine that actually does all the work for you is called a hydroseeder.
Shark Skin-Like Surface Fights MRSA. Surfaces covered in a micropattern mimicking the ridges of shark skin could reduce the spread of drug-resistant Staphylococcus aureus and other superbugs in hospitals. With the rise of microbes that have evolved resistance to even the most powerful antibiotics, researchers are getting creative.
Like rays, shark skeletons are made of cartilage. The shape of a shark is specially designed to help it navigate long distances and maneuver around its prey with ease. Its several pairs of fins help it navigate through the water, kind of like our legs get us humans around, and our arms help us keep our balance.
