But what really happened is pretty cool!” »
The once-great science twitter is, depending on who you talk to, either dying or dead. Once a vibrant place for many discussions related to my fields of marine biology, ocean conservation, and public science communication, it’s been described now as an abandoned shopping mall that’s been taken over by neo-Nazi gangs. Lots of people have … Read More “Bluesky is now open. Science Twitter, here’s how to use it!” »
In which I attempt to answer an interesting question I received during a public talk. Much of the focus of my career in shark research, policy, and communications has been influenced by my time doing public science engagement on social media. I’ve attended dozens of scientific conferences and conservation policy meetings, I’ve spent thousands of … Read More ““If that’s so important to shark conservation, why have I never heard of it?”” »
