We know CFL bulbs are world-changingly efficient, producing the same level of light as their incandescent parents while using a quarter of the energy. But they're still a relatively new device, and few long-term studies have been carried out on them. One of the most recent, a new report from a team at Stony Brook, suggests CFLs might cause damage to skin by releasing UV rays.
Scientists at the not-suspiciously-named-at-all Northeast Normal University in China have come up with a new textile that's remarkably resistant to the horrors of both water and sunlight. In fact, it offers more than double the amount of UV protection required to attain "ultimate" UV protection status.

Finally, some good news on the climate. Good, but hesitantly good, mind you. British scientists working in a remote area of the tropical Atlantic have discovered that ozone levels there were 50 percent lower than expected. The reason for the discrepancy is due to a process in which UV rays from the sun are the catalyst for a series of chemical reactions which end with the breakdown of ozone and methane.
