Today's episode covers groundbreaking discoveries that are reshaping our understanding of Earth and beyond. UC Riverside scientists reveal a hidden climate feedback mechanism that could explain past ice ages while presenting a warming paradox. We explore evidence suggesting the universe's expansion may be slowing down, challenging decades of dark energy theory. Plus, Antarctic glacier Hektoria loses half its mass in just two months in the fastest retreat ever documented, and researchers create a revolutionary gel that regenerates tooth enamel without fluoride. We also dive into CRISPR breakthroughs reversing memory loss in aging and Northwestern's nanomedicine innovation making chemotherapy 20,000 times more powerful.
