Ask A Dentist. Feb. 21, 2020, Part 1
Brushing Up On Tooth Science
Most of us spend our time at the dentist holding our mouths open, saying “ahhh,” and occasionally sticking out our tongues. But if you could ask a dentist anything, what would you want to know?
Ira asks University of Utah researcher Rena D’Souza and UPenn’s Mark Wolff about cavity formation, the oral microbiome, gum disease, and the future of stem cells in teeth restoration. Plus, NYU researcher Rodrigo Lacruz explains new research on how excessive fluoride can disrupt tooth cell functions and why you should still keep drinking that fluoridated tap water.
East Africans Battle A Plague Of Locusts Brought On By Climate ChangeA swarm of locusts the size of a city may sound biblical, but it’s the reality right now in East Africa. The pest is devouring the food supply of tens of millions of people, wreaking havoc on crops and pasturelands. Local residents are doing all they can to keep the swarms at bay, but the locusts may be here to stay for a while, as experts suggest their presence may be due to climate change.
Sarah Zhang, reporter at The Atlantic, tells us about the locust issue along with other science news from the week.
Why Coal Country May Be Going SolarA new bill passing through the West Virginia state legislature would increase the state’s solar capacity by 2,500%. Environment reporter Brittany Patterson at West Virginia Public Broadcasting tells us the State of Science.
