Are Sharks Just Preditors?

Gun Violence Is A Public Health Issue

As illustrated by the school shooting in Uvalde, Texas this week, gun violence is a pervasive issue in the United States. The entire Science Friday team extends our condolences to everyone affected by this tragedy.

One reason gun violence is so difficult to understand is that for a long time, there was a federal freeze on funding gun-violence research. That was due to the “Dickey Amendment” which was instated in 1996. This rule barred the Centers for Disease Control and Prevention from using funds to fund research into gun violence, with the reasoning that research into this area would “advocate or promote gun control.”

The 2020 federal omnibus spending bill reinstated funding for this research for the first time in more than 20 years, opening up research into gun violence. This comes during a time where healthcare professionals, including pediatricians and epidemiologists, have elevated their voices to say that gun violence is a public health issue. Firearm-related injury is now the leading cause of death of children and adolescents in the United States.

Joining guest host John Dankosky to discuss gun violence as a public health issue is Roxanne Khamsi, science writer based in Montreal, Quebec.

 

Don’t Panic About Monkeypox Yet, Says Expert

This week, the Centers for Disease Control and Prevention announced it was investigating five cases of purported monkeypox that had been found in the United States. This is a disease that’s endemic to parts of central and west Africa, and is rarely seen outside of those regions. The small number of cases here in the U.S is unusual.

Monkeypox can spread from person to person through skin-to-skin contact or respiratory droplets. Its most striking symptom is an active rash and lesions in the mouth, though can also present as flu-like and include fever, headache, and soreness.

As we’re still grappling with our COVID world, many people are concerned about this new illness. Dr. Anne Rimoin, professor of epidemiology at UCLA’s School of Public Health in Los Angeles, California, joins guest host John Dankosky to explain what’s going on with this wave.

 

Baby Formula 101: Feeding During A Shortage

If you’re the parent of a newborn, you’ve likely experienced how difficult it’s gotten to find your little ones’ favorite baby formula. In February, Abbott Nutrition, a major manufacturer of baby food and formula, shut down a factory in Michigan. This came after the FDA began investigating serious—and even fatal—bacterial infections in infants who were fed formula from the plant.

This one factory produces around a quarter of the United States’ baby formula, so closing it has left store shelves empty and parents scrambling to feed their babies. In a desperate state, many parents have resorted to switching their babies’ formula, seeking out donated breast milk, and even making formula at home.

Guest host John Dankosky speaks with Dr. Bridget Young, an assistant professor of pediatrics at the University of Rochester and founder of Baby Formula Expert, about the makeup of baby formula, why it’s so important, and how parents can safely feed babies during the ongoing shortage.

Breast Milk Banks Are Struggling To Meet Demand

The nationwide shortage of baby formula is also impacting Hoosier families. More than 40 percent of retailers across the country reported being out of formula stock during the first week of May, according to Datasembly, a firm that collects data from grocery stores and other retailers. The Milk Bank is an Indianapolis-based nonprofit that provides donated breast milk to babies in the neonatal intensive care unit and babies with medical needs who benefit from human milk. Advancement Director Jenna Streit said the organization is seeing an increase in requests from families desperate to feed their babies.

Diving Into The Deep World Of Sharks

Sharks are some of the longest-enduring residents of our planet—there were shark relatives in the oceans before Earth had trees, and before the planet Saturn got its rings. But now, many species of shark are threatened, mainly as a result of unsustainable fishing practices.

Dr. David Shiffman, marine researcher and social media shark advocate, writes in his new book Why Sharks Matter: A Deep Dive with the World’s Most Misunderstood Predator about people’s fascination with sharks. He shares some amazing shark facts—did you know that Greenland sharks can live for 400 years, and some have been found with the remains of polar bears in their stomachs?

Shiffman joins John Dankosky to share his shark lore, and to talk about the role of sharks in the ocean ecosystem, safety around sharks, threats to their survival, and what individuals can do to help protect these powerful, yet misunderstood, creatures.

 

Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
