In China, a South-South Exchange Helps Countries Yearning for Clean and Efficient Heating Learn from Each Other

Places with cold climates need access to a reliable and efficient heat supply for the health of their population. But in developing countries, the majority of rural and peri-urban households do not have access to centralized heating or gas networks. Instead, they use traditional heating stoves that use solid fuels like coal, wood, and dung for heating. These stoves are often inefficient (with thermal efficiency as low as 25%-40% compared to 70% or above for efficient stoves) and emit large amounts of pollutants (e.g., CO and PM2.5), causing indoor and outdoor air pollution with negative health and environmental impacts.

While most people link air pollution only to burning fossil fuels, other activities such as agriculture and biomass burning also contribute to it. The complexity of air pollution can be explained by analyzing the composition of the PM2.5, one the most important air pollution indicators. 
 

As HIV/AIDS cases increase in the Philippines, so does activism

It was Christmas dinner two years ago, in 2010, among my gay friends. I just came back from an expat assignment in the US, and was greatly enjoying the uniquely Filipino way of celebrating the cheery season. Towards the end of that dinner, one of my close friends came up to me saying he wanted to speak with me in private.

The two of us went outside the restaurant, and in a dark corner of the parking lot he told me he wanted me to be among the first to know. Early that month, he had himself tested for HIV, and found out he was positive. I was so shocked that no words came out of my mouth, I remember just giving him the tightest hug I could, my mind blank, my heart racing, not knowing what to say or do next. He was my first close friend who came out to me as HIV-positive.
