Surgeons Perform First Successful Penis Transplant In The United States

A 64-year-old man who lost his penis to cancer is America’s first recipient of a penis transplant. The experimental procedure is poised to help thousands of men who have lost their genitals to disease, accident or combat.

Thomas Manning, a bank courier from Massachusetts, is the first man in the United States to receive a genitourinary reconstructive (penile) transplant.

Report: Four Out Of Five City Dwellers Breathe Unsafe Air

The leading cause of death worldwide isn’t an infectious disease or cancer. It’s air pollution. And despite our best efforts to control it, smog is still increasing at an alarming rate worldwide, posing a health risk to over 80 per cent of all city dwellers.

That’s the sobering conclusion of an update released today by the World Health Organisation, whose global air pollution database tracks annual mean concentrations of fine particulate matter — tiny particles of sulfates, nitrates and carbon that bury themselves deep in human lungs. The WHO was able to compare information on particles smaller than 10 or 2.5 microns (PM10 and PM2.5) across 795 cities in 67 countries between 2008 and 2013.
