Winners of the 2022 Regeneron Science Talent Search are announced

　　Transcript¹

　　Two high school winners in the Society for Science and Regeneron's annual STEM competition talk about their winning projects.

　　LEILA FADEL, HOST:

　　Some of the brightest and best high school seniors in the U.S. are celebrating. The newest winners of the nation's oldest science and math competition have been selected.

　　A MARTINEZ, HOST:

　　Each year, the biotech company Regeneron and the Society for Science call for students to develop innovative² ideas. This year's two top winners, picked from more than 1,800 applicants³, are Christine Ye from Washington and Victor Cai from Pennsylvania. Ye won first place for a project that looks at black holes and neutron⁴ stars.

　　CHRISTINE YE: Black holes are these objects with gravity that's so strong that not even light can escape. And a neutron star is the collapsed⁵ core of a dead star that's also extremely dense⁶. And so when these objects collide together, you get very, very strong explosions.

　　MARTINEZ: Strong enough to create gravitational waves.

　　CHRISTINE: They are these really cool ripples⁷ in the fabric⁸ of space itself.

　　FADEL: Ye says studying gravitational waves can teach us more about those colliding space objects.

　　CHRISTINE: ...Things like how big the black hole is or how fast the neutron star is spinning.

　　VICTOR CAI: I built a narrowband short-ranged distance-sensing radar⁹.

　　FADEL: And that's runner-up Victor Cai, whose project uses a different kind of wave right here on Earth. It's a kind of radar that calculates distance by transmitting two signals at different frequencies.

　　VICTOR: I started looking into short-range distance sensing that I could test in my home. And I realized that for radars¹⁰ with limited bandwidth, it's actually extremely difficult to (laughter) sense distance in the short range.

　　MARTINEZ: Cai found he was limited by the narrow slice of Wi-Fi bandwidth we all use where it's legal for citizens to transmit waves.

　　VICTOR: And so my project was able to get around the bandwidth restrictions¹¹ and achieve the same resolution as a traditional radar, but using five magnitudes less bandwidth.

　　MARTINEZ: This means Cai's radar works without interfering¹² with other wireless¹³ or Bluetooth devices in a building.

　　VICTOR: There's many applications, such as medical sensors¹⁴, where you don't want the sensors to be interfering with each other, additionally with autonomous¹⁵ vehicles.

　　FADEL: And yes, he does mean self-driving cars. Cai says his project could help prevent collisions.

　　Victor Cai and Christine Ye, congratulations.
