Already lasers can obliterate skin blemishes, topically applied drugs can smooth facial lines and injected agents can remove deep wrinkles. Future products will be faster, better and longer lasting. "New substances will be developed by entrepreneurs," says Brian Mayou, an aesthetic plastic surgeon, "that will be more successful than liquid silicone that we use today to eradicate wrinkles." The next major breakthrough, says Mel Braham, plastic surgeon and chief executive of the Harley Medical Group, will be laser treatment that needs no recovery period. Nicholas Lowe, clinical professor of dermatology at the University of Los Angeles, adds: "There will be more efficient anti-oxidants to help reduce sun damage and aging. There will also be substances that increase the production of new collagen and elastic tissue to maintain the elasticity of youthful skin." Lee Shreider, a research cosmetic chemist, says that we may be able to look better without any kind of operation as semi-permanent make-up gets better. "Crooked noses will be improved by effectively sealing on shaded colors that either enhance or subdue areas of the face. We will be able to straighten eyebrows and lips making the face more metrical—which remains one of the keys to beauty, and even close blocked pores with permanent, custom-designed foundation." The development of the safe Sun tan is a potential gold mine. Being researched at the University of Arizona, but a long way from reality, is the injectable tan. Professor Lowe is optimistic: "There will almost certainly be a safe way of developing a sunless tan that protects against sun damage. In animal research, we’ve applied creams to guinea pigs that can actually ’turn on’ some of the genes that produce pigmentation without any sunlight exposure.\ What is the main topic of the passage

It took no time at all for the native Americans who first greeted Christopher Columbus to be all but erased from the face of the earth. For about a thousand years the peaceful people known as the Taino had thrived in modern-day Cuba and many other islands. But less than 30 years after Columbus’ arrival, the Taino would be destroyed by Spanish weaponry, forced labor and European diseases. Unlike their distant cousins, the Inca, Aztecs and Maya, the Taino left no pyramids or temples—no obvious signs that they had ever existed. But it is a mistake to assume—as many scholars have until quite recently—that the absence of abundant artifacts meant the Taino were necessarily more primitive than the grander civilizations of Central and South America. They simply used less durable materials: the Taino relied on wood for building and most craftwork, and much of what they made has disintegrated over the centuries. However, thanks largely to two remarkable digs undertaken recently, archaeologists will be able to enrich their knowledge of the Taino. There nearly intact remains of a Taino dwelling buried in the dirt. This site may have been one of the Taino’s major centers. Meanwhile, deep in the forests of the Dominican Republic, a U. S.-Dominican team has also made an important discovery: a 240-ft. deep Taino cenote, or ceremonial well, where hundreds of objects thrown in as offerings have been preserved in the oxygen-poor water. It will take a much longer time to understand the Taino fully, but they have been rescued from the ignoble status of footnotes in the chapter of history that began with the arrival of Columbus. It is assumed the Taino had a comparatively low civilization mostly because ______.
