Podcast appearances and mentions of david nowak

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. 

Alan and Ekaterina are joined in studio by former World #5 Anna Chakvetadze to talk tennis, life changes and post-sports career. On the phone, Leitrim man and Producer/Host of @Team33 Raf Diallo shares his disappointment of Ireland's performances, while David Nowak calls from Switzerland to let us know Alan owes him coffee, and a dirty secret of a famous Moscow-based sports journalist!

We enter a better kind of urban jungle on this episode all about the science and economics of trees in cities -- way more interesting than you might think at first. Yep, there's a big economic argument for more trees in our cityscapes. Our guests here apply scientifically backed dollars-and-cents appraisals to the trees that line our streets or green our downtowns. And they discuss tools you can access to tally such values where you live. And, yes, we also discuss the much-harder-to-quantify relationship that humans and trees have shared since the dawn of man -- and what that means for city neighborhoods lacking in greenery. A lot to think about -- and surely a few surprises -- in the episode.

The urban forest often goes unnoticed but it has a big impact on quality of life. Also often overlooked is the use of wood as a source of home heating and power production. The show features David Nowak of the U.S. Forest Service and Dr. Timothy Volk.
