Condensed down, all the gas that makes up the ozone layer would be no thicker than two pennies. With such a fine film protecting us from the sun's lethal ultraviolet rays, any loss to this shield could have grave consequences to human health. Some evidence suggests that living under cosmic bombardment is a non-too-distant reality as climate change thins the ozone and allows more and more UV rays to get through. And that means one thing – more skin cancer. This growing risk makes understanding skin cancer more important than ever, but happily, progress is being made. For instance, new research identifies a gene that could hamper skin cancer. When this genetic code is inserted into cancer cells, they don't develop the fibrous scaffold (stained in green) they need to grow and move about. Stemming the tide of climate change is becoming ever more vital; ...meanwhile at least biomedical scientists are doing their part.
