UV Damage, Preventing Heart Attacks (Abstract Science June 12 - 16)
Hope for a better lung cancer treatment, producing oxygen with light exposure and can you get a suntan without any UV damage?

Everyone looks better with a suntan, right? Doctors are hopeful that a new compound will give human skin a suntan without the sun. This new compound would also combat skin cancer by keeping people away from harmful ultraviolet (UV) rays. Under the microscope, the tan produced by the compound looks just like a natural tan unlike spray tans and other sunless tanning products, which rely on dyes to stain dead skin cells and which provide no UV protection.

Australian researchers have developed a new method for finding participants for clinical trials that are more likely to respond to a new type of lung cancer therapy now in development. Researchers from Melbourne's Walter and Eliza Hall Institute (WEHI) were optimistic that the new recruitment process will boost the success rate of drugs being trialed as treatments for squamous cell carcinoma of the lung, the second most common type of lung cancer. Using a research tool that mimics the complexity of human tumors, the researchers identified a 'biomarker' that would better categorize the patients who would respond to the treatment. They also showed that combining the 'targeted' FGFR inhibitors with chemotherapy had the potential to improve treatment outcomes.

When a heart attack strikes, blood stops flowing to parts of the heart, starving the tissue of oxygen and killing cardiac cells. A new study with rats suggests an innovative way to provide those cells with an emergency supply of oxygen until surgeons restored blood flow with a coronary bypass: infecting the heart with photosynthesizing bacteria that naturally produce oxygen when exposed to light.
