Summary

This episode examines the significant scientific events of 2025, including governmental impacts on research, climate and energy advancements, and the challenges of space debris.

What Happened

The year 2025 has been marked by significant disruptions in the scientific community, largely due to policy changes under the Trump administration. Maggie Koerth highlights the chaos within the CDC, particularly around the measles outbreak in Texas, which resulted in 16 deaths and over 4,500 illnesses due to a freeze on communications.

In energy and climate news, Sophie Bushwick reports that renewable energy sources surpassed coal for the first time globally, thanks in large part to China's infrastructure investments. However, the year was also noted as the second hottest on record despite being a La Niña year, exacerbating ocean acidification and highlighting the complex nature of climate change.

The demand for energy has increased, driven by the rise of AI, with Virginia becoming a hub for data centers. Ella Nilsson's reporting at CNN pointed out the ripple effect on energy bills in neighboring Maryland.

On a hopeful note, new clinical trials suggest GLP-1 drugs, initially for diabetes, show promise in reducing the risk of conditions like dementia and fatty liver disease, independent of weight loss.

Geoengineering has gained traction as a potential method to manage solar radiation and combat climate change. However, the conversation is fraught with controversy and concerns over the risks and benefits.

The proliferation of satellites has led to increased space debris, posing risks to astronauts and equipment. Legal restrictions complicate efforts to clean up this space junk, as only countries can manage their own debris.

Lastly, the episode debunks a claim by a company that they resurrected the extinct dire wolf. In reality, they only modified genes in gray wolves, sparking discussions about the implications of genetic manipulation and sensationalism in science.
