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.
Coloration. Sharks are generally a dark color on top, which is called their dorsal side, and a light color on the bottom, which is called their ventral side. Predators looking down might not see the dark top of the countershaded shark, because it blends in with the dark ocean depths.oloration.
