To Help Curb Coral Reef Destruction, Hawaii Wants to Ban Chemical Sunscreens (CS Monitor)

…According to Hawaii's Department of Land and Natural Resources, "researchers have found oxybenzone concentrations in some Hawaiian waters at more than 30 times the level considered safe for corals." ...  there are two kinds of sunblock: Chemical blockers use ingredients like oxybenzone and octinoxate to absorb UV radiation from the sun, preventing it from causing damage. But physical (or mineral) sunscreens, with ingredients like titanium dioxide and zinc oxide, block UVA and UVB rays from ever reaching your skin; and the National Park Service says these have not been found to harm the reefs. Even better: Dermatologists agree that physical blocks are gentler on your skin.

Microbes wake up from 10,000-year nap in cave crystals (CS Monitor)

During exploration of Mexico’s inhospitable Naica caves, a team of scientists managed to extract, and revive, long dormant microbes from inside the giant crystals that populate the caverns. With genetic patterns unlike most other life on earth, the critters may have been dozing for many millennia. / If it holds up, the NASA-backed discovery would raise both hopes for finding life in the extreme environments of other worlds and fears of extraterrestrial contamination by hardy earthborn superbugs.
