What Is Real And Fake? There are two ways to grow a diamond. You can dig one up from the Earth—a product of billions of years of pressure and heat placed on carbon. Or you can make one in a lab—by applying lots of that same heat and pressure to tiny starter crystals—and get it made much faster.  Put these two objects under a microscope and they look exactly the same. But is the lab-grown diamond real or fake? The answer lies somewhere in between. The same goes for many other things, like artificial flavors or our favorite nature documentaries that put a sensational spin on an otherwise unvarnished look at wildlife.  Writer and historian Lydia Pyne would call them “genuine fakes” and she explores some of them in her latest book Genuine Fakes: How Phony Things Teach Us About Real Stuff. She joins Ira to talk about the vast gray area between real and fake when it comes to science.  How Are COVID-19 Numbers Counted? This week, the death toll attributed to the new coronavirus outbreak passed 2,000 people. And while that number is solid, many of the other numbers involved with this disease, including the total number infected and the degree of transmissibility of the virus, change from day to day. Those shifting numbers are in part due to changes in how countries, such as China, are diagnosing patients and defining who is “infected.”   It can be difficult to know what information deserves attention, especially when information on possible transmission routes and timelines for vaccine development shift constantly. Helen Branswell, senior reporter on infection diseases at STAT, joins Ira for an update on COVID-19 and a conversation about evaluating medical information in the midst of a developing story. An Ancient Burial In A Famous Cave Recently, modern archaeologists returned to Shanidar Cave, located in what is now Kurdistan, and found more Neanderthal remains, including a partial “articulated” skeleton that appears to have been deliberately positioned in a trench near the earlier discoveries.  Emma Pomeroy, a lecturer in the department of archeology at Cambridge University, was the osteologist on the recent archeological team. She says the new find could provide insights into how Neanderthals viewed their dead, their sense of self, and more.
