Summary

Conserving More Than Just the Planet’s ‘Beloved Beasts’ Historically, “conservation” simply meant not overhunting a game animal, preserving sufficient populations to continue to hunt the following year. Over time, however, conservationists have learned to broaden their focus from individual animals to entire ecosystems, protecting not just species, but the food webs and habitat they need to thrive. But the evolution of conservationist thought hasn’t been straightforward. In her new book Beloved Beasts: Fighting for Life in an Age of Extinction, science journalist Michelle Nijhuis profiles some key figures in the history of the conservation movement–from well-known names such as John Muir, Aldo Leopold, and Rachel Carson, to lesser known figures such as 1930s-era bird lover Rosalie Edge. Nijhuis explains how some of these conservationists did the wrong thing for the right reasons, while others managed to do the right thing despite misguided or short-sighted thinking. SciFri’s Charles Bergquist talks with Nijhuis about how conservationist thought has progressed, and her hopes for the future of the movement.     The Plight Of The North Atlantic Right Whale Every year, Earth Day is a reminder that we share this planet with many other species, large and small. And every year, humans have to reckon with the impact we have on those species—like the recent case of the disappearing North Atlantic Right Whale. Experts estimate there are fewer than 400 right whales living off the coast of the North Atlantic. Less than 90 are reproductive age females. Their declining population and poor birth rate can be largely explained by one thing: humans. Boat strikes and entanglements in lobster fishing gear accounted for nearly two thirds of right whale deaths in the last decade—and new research suggests those deaths are being undercounted. A new documentary called “Entangled,” by Boston Globe reporter and filmmaker David Abel, gives us a glimpse of what these encounters are doing to right whales, introducing a slew of researchers, conservationists, lobstermen, lawmakers and politicians who are tangled up in the effort to save the species from extinction. Charles “Stormy” Mayo, a Senior Scientist at the Center for Coastal Studies, and Melanie White, a project manager for the North Atlantic Right Whale Conservation at the Clearwater Marine Aquarium Research Institute—both featured in the film—join Ira to discuss the tragic story of the right whales, and the simple, high-tech solution that is getting little attention and even less research funding. Plus, Massachusetts implemented a nearly state-wide ban on lobster fishing in all state waters from February through early May, giving right whales an opportunity to feed unencumbered in Cape Cod Bay as they migrate. The ban also gives local scientists an opportunity to monitor the pods, tracking which whales have returned, and how they’re fairing. WCAI environment reporter Eve Zuckoff shares thoughts on her recent journey out into the bay with right whale scientists.     It’s Okay To Be Confused About J&J’s Vaccine This week, the FDA and CDC both recommended a temporary pause in distribution of Johnson & Johnson’s one-shot COVID-19 vaccine, after the emergence of a very rare, very unusual blood clotting side effect. The clots, which block blood leaving the brain, have been found in only six of the nearly seven million people who have already received the vaccine in the U.S. One has died, and another is in critical condition. Vox staff writer Umair Irfan has been reporting on the Johnson & Johnson pause, and joins Ira to explain the challenging balance between side effect risks—the rarest of which cannot be detected in clinical trials and therefore naturally emerge when vaccination moves to the general population—and the benefits of protecting people from COVID-19. Plus, what recommendations the FDA may end up making. He also talks about why a small number of people are still getting COVID-19 after being fully vaccinated, the grim outlook for wildfire in the West this summer, and more science stories from the week.

Johnson and Johnson COVID-19 vaccine.

After the data showed rare instances of an unusual blood clotting condition.

How rare are we talking? Well, six people out of seven million who have received the vaccine,

all of the women, between the ages of 18 and 48.

Dr. Anthony Fauci has said he expects the pause to last from days to weeks,

while the FDA decides on recommendations for how to move forward.

For a similar clotting issue linked to the AstraZeneca vaccine, meanwhile,

the U.K. has advised that people under 30 opt for a

back, Umair. Thanks, Ira. Let's get right into this. You've been reporting on this

J&J pause. Do we know why the vaccine might have caused these clots? Well, it's just speculation at this

1:21.6

point, but it may be that the spike protein that is generated by these vaccines, the vaccine administers the

1:29.8

instructions to your human body for making the protein, and then the body uses that protein as a

1:34.8

target for its immune response. And so the idea may be that this is actually triggering an

1:39.8

autoimmune reaction that is triggering blood clots. But critically with this condition, it's not just that they're causing clots, but also

1:46.5

that they're causing another related condition called thrombocetopinia, which is a low level

of blood platelets.

And that's why regulators are really worried, because these two conditions together
