Dinosaurs ruled the earth for many millions of years, but only after a mass extinction took out most of their rivals. Just how that happened remains a mystery — sounds like a case for paleoclimatologist Celina Suarez! This encore episode, Suarez walks us through her scientific detective work, with a little help from her trusty sidekick, Scientist in Residence Regina G. Barber.

This week's science news roundup reunites All Things Considered host Ailsa Chang with Short Wave hosts Emily Kwong and Regina G. Barber to dig into the latest headlines in biomedical research, also known as cool things for the human body. We talk new RSV vaccines, vaccination by sticker and a new device helping a man with paralysis walk again. Have questions about science in the news? Email us at [email protected]

Ice in Antarctica is melting really quickly because of climate change. That's driving sea level rise around the world, and the water is rising especially fast in the seaside city of Galveston, Texas — thousands of miles from Antarctica. Why do Antarctica and Texas have this counterintuitive relationship? And what does it mean for a $34 billion effort to protect the city from hurricanes?Read more and see pictures and video from Antarctica here.

Mora Leeb was 9 months old when surgeons removed half her brain. Now 15, she plays soccer and tells jokes. Scientists say Mora is an extreme example of a process known as brain plasticity, which allows a brain to modify its connections to adapt to new circumstances.Read more of Jon's reporting.Science in your everyday got you puzzled?

If you ask a physicist or cosmologist about the beginnings of the universe, they'll probably point you to some math and tell you about the Big Bang theory. It's a scientific theory about how the entire universe began, and it's been honed over the decades. But recent images from the James Webb Space Telescope have called the precise timeline of the theory a little bit into question. That's because these images reveal galaxies forming way earlier than was previously understood to be possible. To understand whether it's physics itself or just our imaginations that need help, we called up theoretical physicist Chanda Prescod-Weinstein.Got questions about the big and small of our universe?
