After quite a bit of skin cancer, there's high interest in preventing it at the Rockhouse. It won't do me much good after a life of reckless self-indulgence but the new protection against UV radiation comes from natural products and they work much better than existing sunblock products. The thought for this one is about the chill'uns. (Science Daily: Boosting the solar protection factor with rationally designed, nature-inspired sunscreens)
Straight to the punchline:
The authors found that the synthesized compounds are characterized by excellent filter capacities in the relevant UV range. In addition they are photostable, much more than, for example, oxybenzene which is a widely used sunscreen in commercial formulations. They do not react chemically and dissipate radiation as heat (but not to such an extent that the skin temperature would rise as well). And, most importantly, when tested in real formulations, the sun protection factor (SPF) rose by a factor of more than two. Thus they could be promising targets for more stable, more efficient sunscreen lotions. Good news for your next summer vacation.

Maybe you're bored, hombre, but Mother probably isn't and the solution is as organic as she may like.
The natural sunscreen molecules are called microsporine-like amino acids (MAAs) and are widespread in the microbial world, most prominently in marine algae and cyanobacteria. MAAs are small molecules derived from amino acids, thermally stable, and they absorb light in the ultraviolet region, protecting the microbial DNA from radiation damage. Thus they are natural sunscreens, which inspired Sampedro and his colleagues to create new class of organic sunscreen compounds.

Ed: that's so sexist in saying 'she may like!'
Since the only creatures on the planet which are, in effect, mothered by males are seahorses, I'll take that grave risk of offending them.
Do you wanna see my scars?
Ed: NO!
That's ok but it's your loss. I explain them as bullet holes when I go to the beach. I got them when I saved the busload of nuns and orphans from the terrorists, see.
