Bacteria with multicolor vision

“MIT researchers have engineered bacteria with “multicolor vision” — E. coli that recognize red, green, or blue (RGB) light and, in response to each color, express different genes that perform different biological functions. To showcase the technology, the researchers produced several colored images on culture plates — one of which spells out “MIT” — by using RGB lights to control the pigment produced …

DIY WIFI RC Car With ESP8266 and Arduino IDE

DIY WIFI RC Car With ESP8266 and Arduino IDE

“This project is an example of remotely controlled car via WIFI. The circuit is based on ESP8266, and the software is written in the Arduino IDE. As an engine driver, I used the L298N. The vehicle’s speed is controlled by PWM in the range of 0 to 1023. Digital control offers more possibilities than the usual controller. I also …

Google Plans to Demonstrate the Supremacy of Quantum Computing

“By the end of 2017, Google hopes to make a 49-qubit chip that will prove quantum computers can beat classical machines. Quantum computers have long held the promise of performing certain calculations that are impossible—or at least, entirely impractical—for even the most powerful conventional computers to perform. Now, researchers at a Google laboratory in Goleta, Calif., may finally …
