A new antenna using single atoms could usher in the age of atomic radio
The team tested their device by recording themselves singing “Mary Had a Little Lamb”
Still pretty large right now… but so are most new technologies initially.

Youtuber and 8th grade science teacher Tom McFadden composed this fun parody of “Choices” by E-40 to promote the amazing power of scientific curiosity. Kudos to Tom and the 76 scientists, engineers, educators, and YouTubers who agreed to participate in this project!
Science is AMAZING, but unfortunately, it is currently being defunded all around the world. Fortunately, you can make a difference. Start by watching this video, and then use democracy to help the world progress to a better tomorrow.
The magnet induced a current in the copper pipe, which in turn produced a magnetic field. The direction of this current then opposed the change in the magnet’s field, resulting in the magnet being repelled and thus falling more slowly. Neat.

Scientists reveal the hidden structure and size of our galaxy
Our galaxy is not what we thought it was. According the paper Rings and Radial Waves in the Disk of the Milky Way—published in the Astrophysical Journal—we should call it the Corrugated Cardboard Galaxy, as shown in the diagram above. Even more surprising: It’s 50-percent larger than previously thought.
"According to Heidi Jo Newberg—professor at the Rensselaer Polytechnic Institute and lead author for this paper—"in essence, what we found is that the disk of the Milky Way isn't just a disk of stars in a flat plane—it's corrugated. As it radiates outward from the sun, we see at least four ripples in the disk of the Milky Way. While we can only look at part of the galaxy with this data, we assume that this pattern is going to be found throughout the disk.""
