Urban Forests And Climate Change, HIV Treatment Progress. September 4, 2020, Part 1
New York City’s skyline is dominated by tall skyscrapers—but there’s a surprising amount of forest in the city known as a concrete jungle. Tree canopy actually covers about 20% of the city. In fact, woodlands are one of the few natural resources the city has.
Reporter Clarisa Diaz, in collaboration with John Upton from Climate Central, shares how the city’s green spaces, both large and small, are needed to create an urban forest ecosystem in the face of climate change. Plus, forester David Nowak talks about the science behind planting an urban forest, and how to determine the value of a tree.
Plus, while all eyes are currently on the COVID-19 pandemic, the coronavirus isn’t the only disease circulating the world. Lockdowns have hindered access to medical care, and supply chains for both tests and medications have been disrupted. With countries allocating limited public health resources to battle COVID-19, longstanding public health threats like tuberculosis, malaria, and HIV/AIDS may be at risk of resurging.
However, there is also hopeful news for communities facing HIV/AIDS. Last week, a study published in the journal Nature examined 64 unusual people who seem to be able to naturally keep HIV at bay. Researchers investigated what makes these so-called ‘elite controllers’ able to manage their infections. They now think powerful T cells—a type of white blood cell which helps regulate the immune system—may hold a clue to these cases.
Furthermore, earlier in the summer, a trial of a long-lasting injectable drug to prevent HIV infection was found to be at least as protective as the existing “pre-exposure prophylaxis,” or PrEP drug, which must be taken daily.
Health and science reporters Apoorva Mandavilli of the New York Times and Jon Cohen of Science join Ira to discuss recent HIV/AIDS developments, and to reflect on 40 years of AIDS research.
