Big Picture Science for Jan 27, 2025: Skeptic Check: Drone Panic

 

Big Picture Science - Skeptic Check: Drone Panic

When several mysterious objects were spotted flying over New Jersey, their unknown identity led to frightening rumors, and triggered frustration and alarm among some residents of the Garden State. What were these objects, and if they were drones, as some appeared to be, were they friendly or foe? Many of the objects have now been identified. We talk about what happened when calmer heads prevailed and consider what the Great Drone Panic might have in common with other episodes involving objects cruising the skies. Also, why one expert thinks the event gave birth to a new UFO subculture.

Guests:

• Andrew Fraknoi - Professor of Astronomy at the Fromm Institute of the University of San Francisco
• Mick West - Investigator of conspiracy theories and UFO sightings
• Greg Eghigian - Professor of history and bioethics at Penn State and author of “After the Flying Saucers Came: A Global History of the UFO Phenomenon”

Big Picture Science for Jan 20, 2025: The Best Things in Life are Tree(s)

 

Big Picture Science - The Best Things in Life are Tree(s)

While humans were leaving the Stone Age and entering the Bronze, some Bristlecone pine trees grew from seeds to sprouts. They’ve been growing ever since. These 5,000-year-old pines are among the oldest organisms on Earth. Superlatives are also appropriate for the towering redwoods.

Trees are amazing in many ways. They provide us with timber and cool us with shade, they sequester carbon and release oxygen, and are home to countless species. But they are also marvels of evolutionary adaptation. We consider the beauty and diversity of trees, and learn why their future is intertwined with ours.

Guests:

• Kevin Dixon - Naturalist at The East Bay Regional Park District, Oakland, California
• Daniel Lewis - Environmental historian and senior curator for the History of Science and Technology at the Huntington Library, art museum and botanical gardens in Pasadena, California, professor of the natural sciences and the environment at Caltech, and author of “Twelve Trees: The Deep Roots of our Future”

Big Picture Science for Jan 13, 2025: The Ocean’s Genome

 

Big Picture Science - The Ocean’s Genome

REPEAT
After helping to sequence the human genome more than twenty years ago, biochemist Craig Venter seemed to recede from the public eye. But he hadn’t retired. He had gone to sea and taken his revolutionary sequencing tools with him. We chatted with him about his multi-year voyage aboard the research vessel Sorcerer II, its parallels to Darwin’s voyage, and the surprising discoveries his team made about the sheer number and diversity of marine microbes and their roles in ocean ecosystems.

Guests:

• Craig Venter - Genomicist, biochemist, founder of the J. Craig Venter Institute, and co-author of “The Voyage of Sorcerer II: The Expedition that Unlocked the Secrets of the Ocean’s Microbiome.”
• Jeff Hoffman - Lab manager at the J. Craig Venter Institute and expedition scientist on the Sorcerer II expedition.

Big Picture Science for Jan 06, 2025: Night Flight

 

Big Picture Science - Night Flight

REPEAT
Owls are both the most accessible and elusive of birds. Every child can recognize one, but you’ll be lucky to spot an owl in a tree, even if you’re looking straight at it. Besides their camouflage and silent flight, these mostly nocturnal birds, with their amazing vision and hearing, are most at home in the dead of night, a time humans find alien and scary. Ecologist Carl Safina got to know an injured baby screech owl well. Their relationship saved the owl’s life and gave Safina insider’s wisdom about these aerial hunters of the night.

Guests:

• Carl Safina – ecologist at Stony Brook University, head of the non-profit Safina Center, and author of “Alfie & Me: What Owls Know, What Humans Believe”
• Tom Damiami – natural resources interpreter, singer on Long Island, NY and leader of the Shelter Island Owl Prowl
• Gordy Slack – science writer, former senior editor of California Wild, the science and natural history magazine published by the California Academy of Sciences
