    When geobiologist Hope Jahren sat down to describe the results of her research, she found that she couldn’t relate her findings without discussing the people who made them possible, herself especially. That revelation led to her new book “Lab Girl,” both an investigation into the complex and thrilling lives of plants and a deeply personal memoir. Jahren joins Jeffrey Brown to explain more.

    Wednesday marks the 36th anniversary of the deadliest volcanic event in U.S. history: the eruption of Mount St. Helens, which killed every living thing in a 230 mile radius. But the slopes around the volcano are now beginning to repopulate with plant and animal life, giving biologists a unique opportunity to watch an ecosystem develop in real time. Science correspondent Miles O’Brien reports.

    Biologist and Pulitzer winner E.O. Wilson has spent his life studying animals and fighting for their conservation. As species go extinct at 1,000 times the normal rate thanks to human interference, Wilson’s new book “Half Earth” holds a bold plan to preserve the world’s biodiversity: set aside half of the entire planet for natural habitats. Jeffrey Brown talks to Wilson for more. Continue reading

    With an estimated 80 million feral cats in communities across the United States, there is growing a controversy on how to deal with them. Euthanizing cats has been the traditional approach, but many animal rights activists believe that approach is cruel and inhumane. Adithya Sambamurthy of Reveal for the Center for Investigative Reporting has the story. Continue reading

    When you watch an insect fly in slow motion, you get a whole new perspective on the complexity of movement and engineering. A new collaborative research project, funded by the U.S. Air Force, is devoted to studying how insects and animals fly so that humans can build smarter, more efficient aircraft. Hari Sreenivasan reports. Continue reading

    The deadly Ebola virus normally spreads among animals but occasionally spills over to humans, to dire effect. To understand how such diseases make that jump, scientists must find the animal host. But the hunt for live samples of Ebola in animals has never turned up a smoking gun. Science correspondent Miles O’Brien follows epidemiologists in Sierra Leone on their hunt for deadly diseases.

    Parliament’s House of Commons just approved further testing on “three-person babies”, a technique that would use the genetic material from three people to create a healthy baby. It’s a misleading term, scientists say, and it doesn’t explain why for some couples this may be their only chance of having a healthy child of their own. Continue reading

    No, it’s not the mythical Loch Ness monster, but 170 million years ago Dearcmhara shawcrossi prowled the warm coastal waters of Scotland in pursuit of fish and other reptiles. Scientists announced the discovery of the previously unknown prehistoric marine reptile in the Scottish Journal of Geology today. An artist’s depiction shows a dolphin-like creature measuring about 14 feet from snout to tail that lived during the Jurassic Period. It’s a moderate-sized ichthyosaur, the dominant marine reptiles that lived in the time of dinosaurs. They were around for 150 million years, until they disappeared about 95 million years ago. This discovery fills in some of the information of the Early-to-Middle Jurassic timeline that has proven hard to crack for paleontologists.
