Innovations in Supersonic Travel and Cosmic Discoveries

Most Powerful Neutrino Ever Is Detected In the Mediterranean

Neutrinos are sometimes called “ghost particles,” because they are nearly weightless, rarely interact with any other matter, and have very little electric charge.

Now, scientists have discovered a neutrino with a recording-breaking level of energy, which could bring us closer to understanding physics underpinning the creation of the universe.

Host Ira Flatow is joined by Sophie Bushwick, senior news editor at New Scientist, to talk more about the latest in neutrino research and other top science news of the week, including supersonic spaceflight without a sonic boom; an asteroid headed for Earth; and why loggerhead turtles are dancing.

Transcripts for each segment will be available after the show airs on sciencefriday.com.
