Endangered species, languages linked at high biodiversity regions Posted: 07 May 2012 12:41 PM PDT Biodiversity hot spots -- the world's biologically richest and most threatened locations on Earth -- and high biodiversity wilderness areas -- biologically rich but less threatened -- are some of the most linguistically diverse regions on our planet, according to a team of conservationists.

Sunscreen ingredient may increase skin cancer risk Posted: 07 May 2012 10:19 AM PDT As vacationers prepare to spend time outdoors this summer, many of them will pack plenty of sunscreen in hopes it will protect their bodies from overexposure, and possibly from skin cancer. But researchers are discovering that sunscreen may not be so safe after all.

Dry rivers, vibrant with culture and life Posted: 07 May 2012 07:23 AM PDT Dry rivers are more than mere desiccated shells of their robustly flowing incarnations, say Australian ecologists. They have qualities and inhabitants distinct from their adjacent riversides wet-phase communities. They are places of isolation and re-connection, and oases for humans and wildlife.

Gaseous emissions from dinosaurs may have warmed prehistoric Earth Posted: 07 May 2012 07:23 AM PDT Sauropod dinosaurs could in principle have produced enough of the greenhouse gas methane to warm the climate many millions of years ago, at a time when the Earth was warm and wet. That's according to calculations reported in the May 8 issue of Current Biology, a Cell Press publication.
