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.
Sharks' eyes are protected when attacking prey. Also unlike humans, shark eyelids serve to protect the eye when attacking prey. Some sharks have a nictating membrane, or a clear membrane that covers and protects the eye when a shark bites its prey. Sharks like the Great White, lacking a nictating membrane, roll their pupils back in their heads for protection when feeding.
