We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.

All SONOFF WiFi and Zigbee home automation devices can now work with the Matter protocol. This can be done in two ways: ...

Researchers have developed a way to 3D print custom micrometer-sized structures directly into the interior of living cells.

Graphene could transform everything from electric cars to smartphones, but only if we can guarantee its quality. The ...

At Utrecht University, a new fluorescent sensor lets researchers watch cellular crises unfold in real time, even inside living animals. Trump’s golf course takeover sparks outrage Lake Erie sloshed ...

A new fluorescent sensor is giving scientists an unprecedented view of how cells respond to DNA damage, capturing the repair process as it unfolds in real time. The tool, developed at Utrecht ...

A special sensor can accommodate various device sizes while recording accurate notes regarding substance levels such as blood, insulin, and IV fluids. A non-contact level sensor does not come into ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

What just happened? Researchers at University College London have developed a new type of solar cell capable of efficiently generating power from indoor light, a breakthrough that could reduce ...

Such sensors could one day carry out MRI at the scale of individual cells or aid researchers in drug development. Fragile quantum states might seem incompatible with the messy world of biology. But ...
