2025/10/22

Green sea turtle conservation shows us what’s possible when people, policy, and passion align. Once nearly wiped out by overharvesting and habitat loss, the green sea turtle has made an inspiring recovery after decades of global protection.

2025/10/20

Coral reefs suffering from climate change are no longer a warning for the future, they are happening now. A landmark scientific report reveals that warm-water reefs have already passed a tipping threshold due to global heating, leading to widespread die-offs and threatening the biodiversity and coastal protection they provide. For the millions of people who depend on reefs for food and livelihoods, this is not just an ocean issue but a global crisis. Global heating is pushing other critical systems

2025/10/15

Vaquita stands as one of the rarest marine mammals on Earth, with fewer than 20 left in the wild. In this episode, we explore what the near-extinction of the vaquita teaches us about the future of sharks and why their survival is critical to the health of the ocean. Sharks play an essential role in keeping marine ecosystems balanced, yet they face many of the same threats that doomed the vaquita: bycatch, overfishing, and weak enforcement. This episode dives into the parallels, the urgency of acting

Mentors: climate change is hopeless—at least, that’s the message many young scientists are hearing from the people they were told to admire. But what if giving up isn’t the only option? In this episode, I respond to a heartfelt email from a marine science student who refuses to stay silent, even when senior scientists tell her that solutions to climate change are naive, misguided, or politically inconvenient.

2025/09/26

Fighting overfishing with AI is transforming how we protect the ocean. A new study revealed that nearly half of all coastal marine protected areas (MPAs) showed fishing vessel presence, with many ships operating “dark” without AIS tracking. This means that even in places meant to be safe havens for biodiversity, industrial fishing has been creeping in unnoticed. Satellites and artificial intelligence are changing that reality. By detecting untracked vessels and guiding patrols, this technology is

2025/09/16

Great white shark DNA is one of the most puzzling mysteries in marine biology. Recent research has revealed that despite being one species, great whites have split into three distinct genetic groups across the globe. What’s even stranger: their nuclear DNA and mitochondrial DNA tell conflicting stories, leaving scientists scratching their heads. Shark philopatry—the tendency of females to return to their birthplace to give birth—adds another layer to this mystery. While philopatry has been well
