Collaborate Disseminate
There are many ways to create printed circuit boards, but one of the more traditional ways involves using boards coated with photoresist and exposing the desired artwork on the board, …read more Continue reading Lasers Make PCBs the Old Fashioned Way
Antibiotics were one of the most important inventions of the 20th century, but their effectiveness is plummeting as bacteria develop resistance to them. Now, researchers at Washington University in St. Louis have shown that ultrashort pulses of laser l… Continue reading Ultrashort laser pulses shred superbugs without harming human cells
There are now a number of bike-mounted devices that laser-project lines onto the road, showing motorists how much passing space they should provide. tether works in a similar fashion, but it also senses passing vehicles in order to produce cyclist-safe… Continue reading tether adds map-making brains to bike-mounted laser safety tech

The US Naval Research Laboratory (AFL) is developing an Argon Fluoride (ArF) laser that may one day make fusion power a practical commercial technology. The wide-bandwidth ultraviolet laser is designed to have the shortest laser wavelength that can sca… Continue reading Argon fluoride laser could lead to practical fusion reactors
In a world where smartphones have commoditized precision MEMS Sensors, the stage is set to reimagine clusters of these sensors as something totally different. That’s exactly what [chronopoulos] did, taking …read more Continue reading Laser Theremin Turns Your Hand Swooshes into Music
Got a couple of old DVD-RW drives lying around, just collecting dust? Of course you do. If not, you likely know where to find a pair so you can build …read more Continue reading Mini Laser Engraver Could Carve Out a Place on Your Desk
You know how it is, you get in late from work, you’ve been stuck in traffic for what seems like an eternity, and you’re hungry. You reach for the microwave …read more Continue reading Microwave Ovens: Need More Power? User Lasers Instead!
Researchers at Columbia have used multi-wavelength lasers to cook 3D-printed chicken. Apparently, it tastes like chicken. We were not overly surprised that 3D printed chicken protein cooked up to taste …read more Continue reading Columbia Decides 3D Printed Food Tastes Like Chicken
Even though it’s now possible to 3D-print foods into millimeter-precise shapes and forms, cooking those printed foods is still a fairly inexact process. Scientists are trying to change that, by using lasers to cook foods to specific optimized standards… Continue reading Lasers could bring the precision of 3D printing to the cooking of food
