Researchers use new technology to communicate with plants electronically. Scientists were able to open a Venus flytrap's leaves using electrical signals. (Photo from NTU)   Thanks to Singapore's Nanyang Technological University's new development, we may start to see a rise in "robo plants." A team of researchers from NTU connected plants to electrodes capable of detecting the weak electrical pulses naturally emitted from the plants. They believe this technology could be harnessed to help f ...
Introduction What does it do? How does the RF Switching internally work? Circuit Walkthrough: RF Switching Switch Selection Controlling the RF Switches Regulated Supply (3.3V) Power On/Off Circuitry Printed Circuit Board Building It Components Basic Test Summary   Introduction This project has been in the back of my mind for ages, and a recent conversation on RF switches with BigG reminded me I really ought to work on it!     ...
POINTER is a new tracking system to help locate firefighters inside smoky buildings. The system is made up of a receiver, base station, and transmitter. (Photo from NASA/JPL)   Firefighters put their lives on the line every day. The fire itself is dangerous, but the smoke can also make it challenging to navigate and soon, the firefighter needs rescuing. To address this issue, NASA’s Jet Propulsion Laboratory and the Department of Homeland Security Science and Technology have teamed u ...
Professor Yaakov Nahmias seen holding the biological chip. (Image Credit: Hebrew University)   I've always had a problem with testing on animals (see my cartoon about it). I know it has been helpful in the past, but I've been hoping to see another way. We are getting closer.   Life-saving drugs are produced every year, but they go through testing in animal models to ensure safe consumption for humans. Now, drug development and testing without animal experimentation have been introdu ...
Elon Musk's monkey, Pager, used a joystick connected to a machine to move the cursor on a color square. Afterward, he was able to control the video game with his brain. (Image Credit: Neuralink) Elon Musk's monkey played a video game using its brain! Neuralink, a company founded by Musk that develops AI-powered microchips to be implanted in human brains, showed a video of a macaque using the technology to play video games, including "Pong." Musk talked about performing trials on monkeys before ...
The NSCU team developed a new mussel-monitoring system to determine if there are toxins in the water. (Image Credit: NSCU)   This seems like an April Fools joke, but it isn't.   Or is it? It's not…. Or is it?   No.   Or is it? J/K, it's not.   Researchers at North Carolina State University developed and demonstrated a new system capable of remotely monitoring freshwater mussels and their behavior. Researchers could use the system to detect toxins in aquatic e ...
