What does hair loss have to teach us about cancer metastasis?  

Researchers have identified a signaling pathway regulating cell migration and metastasis. Unexpected hair loss in a preclinical model helped them to identify the pathway. When cells within the skin that maintain hair follicles migrate too often, hair follicle maintenance is disrupted. Researchers speculated that this pathway might also play a role in cancer cell migration. Indeed, they showed that disrupting this pathway in preclinical models increased metastasis.

Heavy-petroleum fuels raising vanadium emissions  

Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke study finds. These emissions now exceed those from all natural sources combined. Growing evidence suggests exposure to vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma or COPD.
