Baby Right Whales Bring Hope, Tylenol Upcycled from Plastic, Community-Led Wildfire Prevention in Africa and more.

North Atlantic Right whales were once so thoroughly hunted they nearly went extinct. When hunting these mammals was outlawed, they slowly started to bounce back, but today Right whales are dealing with newer deadly threats, such as fishing gear entanglement and warming in the Gulf of Maine. So, it’s a relief to advocates to have a successful calving season like this year with 23 new calves, the most since 2009. Also, scientists in the UK were able to use genetically modified bacteria to turn plastic bottles into the common pain reliever acetaminophen, also known as paracetamol and Tylenol. The lead researcher speaks with us about the potential applications of this biotech breakthrough. And Nigerian conservation ecologist Iroro Tanshi rediscovered the short-tailed roundleaf bat in 2016, after decades when it was believed extinct in the region. The species is still critically endangered, with habitat loss from wildfires as one of its top threats. So Iroro joined with local groups to start a community-led program to develop safer field burning practices and wildfire fighting strategies, and she is the recipient of the 2026 Goldman Environmental Prize for Africa. --- You can help support our free public radio show and podcast, for free, by leaving a review on Apple Podcasts.

PFAS and Our Genes, Artemis II Science and Awe, and Clearing the Air and Climate Solutions Hope

A 2025 study found that exposure to certain PFAS chemicals, which are pervasive and persistent in the environment and human bodies, can lead to changes in gene expression that are linked to cancers, autoimmune and other immune disorders, and neurological disorders. Also, the four astronauts of the Artemis II mission in April 2026 made new scientific observations that are helping to expand our knowledge of the Moon, as well as the Earth itself. Artemis II Lunar Science Lead Kelsey Young joins us to talk about the scientific goals and accomplishments of the mission and the unforgettable moments the crew shared with people back on Earth. And climate solutions like renewable energy tech that requires intensive mining can run into skepticism from people across the political spectrum. But according to data scientist Hannah Ritchie, many of the concerns are based on partial- and misinformation, and the outlook for addressing the climate emergency isn’t as grim as some people may think. Ritchie is the author of Clearing the Air: A Hopeful Guide to Solving Climate Change in 50 Questions and Answers. --- You can help support our free public radio show and podcast, for free, by leaving a review on Apple Podcasts.

A Cemetery Buzzing with Bees, Bluetooth Butterfly Tracking, How Flowers Made Our World, and more.

While honeybees get most of the buzz, most bees don’t produce honey, and most don’t even live in colonies. Instead, they’re solitary bees who build individual nests. A study details an astonishing finding of several million solitary bees in a cemetery in Ithaca, New York. And monarch butterflies can travel thousands of miles each year between Mexico and North America in an epic relay race of multiple generations. Thanks to new technology, our phones and other Bluetooth devices can now tell us what paths these brave little insects take on this journey. Also, lush peonies, delicate hydrangeas, and vibrant roses burst into bloom in early summer, filling gardens and parks with color and fragrance. But flowers are more than their beauty. They’re some of the oldest beings on Earth, and they played a large role in shaping the natural world as we know it. Author and biologist David George Haskell joins us to discuss his 2026 book, How Flowers Made Our World: The Story of Nature’s Revolutionaries. — Find photos, transcripts, links to more information about these stories, and much more at the Living on Earth website, loe dot org!

Saving the Klamath, Salmon, and Yurok Culture; Trump Attempts to Shrink Bears Ears -- Again; Hints of Life on Mars; and more.

The culture of the Yurok tribe in Northern California is deeply intertwined with the Klamath river’s salmon. So, when toxic conditions caused by the dams on the river resulted in a massive fish kill, the Yurok people sprang into action and secured the historic removal of four dams, a story captured in The Water Remembers: My Indigenous Family’s Fight to Save a River and a Way of Life. Also, on July 13, 2026, President Trump issued a proclamation reducing the Bears Ears and Grand Staircase-Escalante national monuments in southern Utah by about 90 percent, to remove almost 3 million acres from monument status. We discuss the significance of these places to several local tribes who co-manage them, and why in their view the President lacks the authority to slash monuments. And on Mars, our planet’s rocky twin, NASA’s Perseverance Rover is seeking signs of past life, and now scientists say they may have uncovered some of the most compelling evidence yet, in the form of complex carbon molecules in Martian mudstones.

Climate Change Speeding Up, Smog and Sunshine – CA’s Cleaner Air, and more.

Current climate change has been well underway for decades, but the rate of that change is now going up so fast that people are noticing things like tornados and extreme heat waves are occurring in places where they have rarely been seen before. How greenhouse gases from burning fossil fuels, the loss of reflective ice and snow, and other changes are causing the Earth to retain extra heat energy from the Sun. Also, decades ago, the Los Angeles basin was often cloaked in a thick blanket of choking smog, but today the skies are comparatively clear. This striking improvement was no accident and is a testament to how scientists, government, and engaged citizens can work together to solve difficult environmental problems. UCLA Environmental Law Professor Ann Carlson reflects on that success as described in her 2026 book, Smog and Sunshine: The Surprising Story of How Los Angeles Cleaned Up Its Air. And one of the national parks you might visit this summer, or any time of year is Great Sand Dunes National Park and Preserve in Colorado, with the tallest dunes in North America. That’s where Living on Earth Explorer in Residence Mark Seth Lender watched the landscape and a local herd of elk as weather came in. Learn more about your ad choices. Visit megaphone.fm/adchoices
