0:00.0 | Understanding the human body is a team effort. That's where the Yachtel group comes in. |
0:05.8 | Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years. |
0:11.0 | Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program. |
0:19.6 | To learn more about Yachtolt, visit yawcp.co.j.jot.com.j, that's y-A-K-U-L-T-C-O-J-P. |
0:28.4 | When it comes to a guide for your gut, count on Yacolt. |
0:33.7 | This is Scientific American's 60-second science. I'm Christopher in Talata. Got a minute? |
0:38.9 | Computer chips have two important parts. The logic on the chip, which computes and executes |
0:44.4 | programs, and then there's the part that sends and receives. Gets data to crunch, sends |
0:49.2 | back the answer. And while that first part, chip logic, has gotten much faster over the years, the transmission part has lagged behind, because data gets sent via electrical signals passing through copper. |
1:00.9 | So researchers designed a chip that exchanges data with light instead. |
1:05.3 | By going into optics, we're able to relieve this fundamental bottleneck of copper, and in doing so, we're able to |
1:14.1 | increase the bandwidth density on the chip, so how fast the chip can take data in and out |
1:19.7 | by an order of magnitude. Chen Sun, a computer hardware researcher at UC Berkeley, and the startup |
1:25.3 | IR Labs. A metal pin on the memory chip in your computer might transmit at 1.6 gigabits per second. |
1:32.3 | Sun's optical connection ups that rate to 2.5 gigabits per second. |
1:36.3 | Not a huge difference on the face of it, but the killer app here is that multiple wavelengths of light, up to 11, |
1:43.3 | can be used simultaneously to send data through a single fiber, |
1:47.5 | which means this technology has potential speeds of 27.5 gigabits per second, |
1:52.8 | more than an order of magnitude faster than today's standard. |
1:55.5 | So that's the extra dimension that we have to scale bandwidth that we don't have with normal electrical |
2:04.0 | signals. |
2:05.5 | The findings appear in the journal in nature. |
