The Ford Foundation's recent $1 million grant to the Los Angeles Times to cover inequality recognizes two important truths about the state of news media, according to this article. One is that newspapers, much diminished though they be, are still the best way to reach a broad audience. And the second is that society needs to find a new way forward to preserve the vital civic function performed by traditional newsrooms, the authors argue.
UVA2 (320-340nm) offers the same photo-biological effects, including tanning ability, as does UVB (280-320nm), while UVA1 (340-400nm) does not.
That said, repeated exposure to UVA1 delivered to the skin in relatively short periods at 2.2 times stronger than the midday sun "constitutes a new experience for humans" as well.
While we have no research on this new experience for humans, SLE patients seem to like it.
