Pass the Nuts

Cashew shells can be used to mop up heavy metals. Nature India reports that researchers have developed an absorbent material from chemically modified cashew nut shells, an agricultural waste product, which is able to remove harmful heavy metals such as copper, cadmium, nickel, and zinc from aqueous solutions. This kind of sustainable solution for cleaning up industrial […]

Ugly, Indeed

Gee, how many of the millions disabled by leprosy do you think will attend England’s “Leper Festival”?
