The cancer-fighting properties of green tea and erectile dysfunction meds. Ever wonder why men who drink green tea and have Viagra prescriptions live so long? Of course you didn't, nobody wonders that. But according to a new study led by Kyushu University's Hirofumi Tachibana, it could be true! He gave mice suffering from cancer a cocktail of green tea and PDE5 inhibitors (the kind of drug in Viagra, Cialis, Levitra, and other brands of erectile dysfunction medication), finding that malignant cells stopped growing when subjects took the healthy/arousing mixture. The EGCG catechin found in green tea has long been thought to have cancer fighting properties, but Tachibana's work shows that the PDE5 enzyme could be stifling it. Luckily, we already have a drug that suppresses PDE5, and it just happens to be used for erectile dysfunction. Tachibana warns the public from trying this remedy at home right now, and in the meantime researchers in the U.S. plan to set up human trials this year. [The Japan Times]
Cell phone towers are killing many birds. The verdict's out on cell phones' link with brain cancer, but it's very clear cell phones are having a negative effect on bird populations. Around 7 million birds have been killed each year by flying into cell towers, according to a new paper in Biological Conservation. And many of them are rare species, such as the yellow rail (2,000 die from cell phone tower collisions each year, and there are only about 20,000 total). Researchers suggest that affixing blinking red lights to the towers could lower deaths by 70 percent. [Scientific American]
