The Landscape of Fear
At Mozambique’s Gorongosa National Park, a bold experiment is playing out to rescue a wilderness on the brink — and demonstrate the powerful role that fear plays in healthy ecosystems.
A new film from NOVA and HHMI Tangled Bank Studios documents one of the most ambitious wildlife recovery projects ever: the reintroduction of African wild dogs into Gorongosa. The project could be a victory for conservation but it’s also an opportunity to test a hypothesis about the role of fear in nature.

The Secrets of Frog Vision
Why do frogs have the biggest of eyes of any vertebrate in relation to body size? How does eye size relate to a frog's lifestyle? Scientists are starting to uncover the answers.

A Complex Mutualism Between Lizard and Lily
On the Balearic Islands of Spain, in the Mediterranean Sea, a complex relationship has evolved between a lizard and a lily. The dead horse arum is a lily that mimics rotting flesh visually, chemically, and thermally to attract fly pollinators. Balearic lizards come calling, too — and it seems to benefit both lizard and plant.

New Pediatrics Research
I have two new stories in the latest Pediatrics Nationwide:
Updated Guidance on Oral Food Challenges: Oral food challenges are integral for allergists to diagnose food allergies. In 2009, the Adverse Reactions to Foods Committee within the American Academy of Allergy, Asthma & Immunology published a report providing guidance for safely conducting an oral food challenge. Now, an update to this report has been published that expands on previously established guidance and provides more practical information for clinicians and patients.
Advances in Neonatal GERD: Differentiating gastroesophageal reflux (GER), which is defined as the passage of gastric contents into the esophagus, from GER disease (GERD), when reflux is associated with troubling symptoms, remains a challenge in infants. Now, two new papers from Nationwide Children’s provide new evidence-based insights into diagnosing, classifying and treating GERD in infants.
Cardiomyopathy in Mothers of Boys with Muscular Dystrophy
Duchenne and Becker muscular dystrophy are progressive neuromuscular diseases caused by mutations in the DMD gene, which encodes the protein dystrophin. About two-thirds of patients (nearly all boys) inherit the mutation in an X-linked recessive pattern from their mothers. It was thought that female carriers of this mutation would be protected from expressing the disease due to the normal copy of the DMD gene on their second X chromosome. But a new study from Nationwide Children’s Hospital reports about half of women who carry the genetic defect responsible for muscular dystrophy show evidence of cardiac fibrosis.
