If your garage door opener is giving you trouble, you may have hidden problems that demand more attention than just replacing some batteries.

The discovery of the visible light-emitting diode (LED) 50 years ago by Holonyak and Bevacqua and the associated demonstration of the viability of the III-V semiconductor alloy created a foundational ...

When it comes to upgrading your bathroom, lighting plays a crucial role—not just for functionality but also for style. You might be wondering whether to buy a mirror cabinet that already has built-in ...

Testing a new headlight before you install it can save time, money, and frustration. Whether you’re checking a replacement bulb, troubleshooting a headlight that seems to have gone out, or just want ...

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

A new approach called monolithic synchronous integration enables the direct fabrication of lead-based optoelectronic devices on silicon circuits, ...

40Hz light and sound stimulation improved memory, neural connectivity, and neurogenesis in mice modeling Down syndrome.

Twelve-year-old Akil Ashraf took it a step further, experimenting with two LEDs in a single circuit. “I want to make a castle and light it up, just like in the game,” he shared. SCRF’s 2025 edition, ...

We use battery packs, LED lights, hobby motors, and buzzers to explore electricity in a fun, hands-on way. We were inspired by this TED talk by AnnMarie Thomas to develop this activity. Check out the ...

The field of photonic integrated circuits focuses on the miniaturization of photonic elements and their integration in photonic chips – circuits that carry out a range of calculations using ...

The larvae of an annelid worm use nitric oxide signalling to activate the neural pathways needed to swim away from the harmful ultraviolet light of the sun.
