Big Picture Science for Sept 21, 2026: How Hot is Too Hot?

A vast cracked desert floor stretches into the distance, colored in deep reddish-brown tones. The ground is broken into irregular plates with dark gaps between them, suggesting extreme dryness. On the horizon, a large, bright sun dominates the sky, surrounded by a glowing halo of light. The sky is filled with dramatic clouds and warm colors, shifting from intense orange near the horizon to darker tones higher up, giving an impression of intense heat and arid conditions.









Big Picture Science: How Hot is Too Hot?

REPEAT
Extreme heat is taking its toll on the natural world. We use words like “heat domes” and “freakish” to describe our everyday existence. These high temperatures aren’t only uncomfortable - they are lethal to humans, animals, and crops. In search of an answer to our episode’s question, we discuss the dilemma of an ever-hotter world with an author who has covered climate change for more than twenty years.

Guest:

  • Jeff Goodell – author of “The Heat Will Kill You First: Life and Death on a Scorched Planet.”

Big Picture Science for Sept 14, 2026: A Coup de Grace in Space

A large space telescope against a purple galaxy background. The main object is a dark, angular telescope structure with a wide circular opening at the center, showing nested rings leading inward, suggesting the primary mirror or optics. The housing has multiple flat, faceted surfaces and panels, giving it a futuristic, mechanical appearance. Around it is a vivid cosmic scene with purple and pink nebula-like clouds, scattered stars, and a few bright white galaxies, emphasizing that this is an astronomical or space-observatory instrument.









Big Picture Science: A Coup de Grace in Space

A new space telescope will soon give us an expanded field of view of some of the strangest phenomena in the cosmos. The launch of NASA’s Nancy Grace Roman Space Telescope will initiate this instrument’s contributions to the understanding of black holes, dark matter, and dark energy. It will also further the search for exoplanets. The project’s principal and deputy investigators join us to describe the telescope’s science goals, and astrophysicist Neil DeGrasse Tyson provides his big picture view of the most exciting recent discoveries in astronomy and cosmology.

Big Picture Science for Sept 07, 2026: Malawi: A Path Forward

A young woman with dark brown skin and short, tightly braided hair holding a newborn baby wrapped in a patterned cloth. She is seated on a surface covered with colorful patterned fabrics and blankets. She wears a simple dark short-sleeved top and is leaning slightly forward, looking down at the baby with a gentle, soft expression. The baby has medium-brown skin and is swaddled up to the neck in a bright, multicolored fabric with geometric patterns, only the small face visible and turned slightly toward the woman. The background is indoors and out of focus, with more fabrics and what appears to be a bag or bundle behind her, giving the impression of a modest, possibly shared space.








 

Big Picture Science: Malawi: A Path Forward

The abrupt defunding of USAID in 2025 caused global shockwaves. The cuts thrust recipient countries who were dependent on foreign aid for medical care into health crises. One area that has been particularly hard hit is Malawi, a country in southeastern Africa where doctors and community organizers are struggling to fill the gaps in essential services left in the wake of the USAID cuts. The loss of local outreach clinics and lack of fuel for ambulances has caused severe delays—and sometimes tragic outcomes—in providing care to mothers and children. A year out from the cuts, we look at how Malawi is rethinking its relationship to foreign aid as it considers how to continue providing vital health services.

In the first of a series supported by the nonprofit Pulitzer Center and in collaboration with Science Magazine, we provide an on-the-ground look at the impact of USAID defunding on health services in key spots across the globe.
