Like a glowing Etch-a-Sketch, LumoPad lets you draw with light

Add as a preferred source on Google

LumoPad is one of the more interesting products to appear on Kickstarter. It’s a lightweight portable drawing board that lets users draw using focused beams of light so that their sketches glow in the dark.

While there are a handful of existing drawing boards for use in the dark, LumoPad stands out because of how it works. The device relies on phosphorescence, which involves a material absorbing light and then re-emitting it over a prolonged period. That means that instead of traditional drawing tools like pencils or brushes, you can “draw” on LumoPad using LEDs, lasers, or even regular flashlights. The drawings don’t need to be erased, either — since they just fade on their own after a few minutes.

“I originally discovered the phosphorescent drawing effect when I was in grade school,” creator Nestor Tkachenko told Digital Trends. “Like many kids, I used to be interested in ‘glow in the dark’ things and lasers. Once at night I was pointing a UV laser at random things in my room, and then suddenly saw the laser leave a bright green streak of light on something. I got closer and realized that the laser had drawn on a bag of phosphorus glow powder. I glued a bunch of the powder onto a piece of cardboard and showed my friends this awesome effect when they came over.

“Almost a decade later, I was throwing out some of my old stuff after stumbled across this piece of cardboard, and decided to play around with it. I quickly decided to make a ‘cleaner’ version and try to make the board I’d had so much fun with available to everyone, [so I set out to] accomplish this by putting it on Kickstarter.”

The cheapest campaign pledge asks for just $20, which will net you a standard LumoPad with a UV LED keychain for drawing. If you’re feeling a bit more flush, however, a pledge of $100 or more buys you a huge 20-inch by 30-inch LumoMegaPad, a regular LumoPad, 3 LEDs, and a UV laser to draw from a distance.

After that, it’s time to start sketching.

LG says its AI found a new hair-loss ingredient after searching 420,000 candidates in a day
LG wants AI to do more than chat—it just used one to find a hair-loss ingredient
LG EXAONE Discovery Hair Loss Ingredient Featured

Most AI demos still involve asking a chatbot to summarize an email, generate a picture, or even get medical advice on occasion. LG has a new assignment for the tech, and it's about finding a better cure for hair loss. LG AI Research says its EXAONE Discovery system screened more than 420,000 candidate compounds in a single day and helped identify an ingredient called Rhamsydil in collaboration with LG Household & Health Care.

Developed with LG Household & Health Care, the material is being investigated for hair-loss care and is already being prepared for commercialization. LG says Rhamsydil could help with female-pattern hair loss by creating a scalp environment more conducive to hair growth, with plans to use the ingredient in products from its Dr.Groot scalp-care brand.

Scammers are teaching AI to sound like you, and research says our brains are falling for it
Has your accent just become a security vulnerability? AI scammers are getting too good at sounding local
Scammers are turning trusted news brands into investment traps

The next scam call you receive may not sound like a robot, a call center, or even someone pretending to be your relative. AI voice generators have become capable of reproducing regional accents and dialects that sound convincing enough that researchers are warning they could become a potent social-engineering tool.

For example, a scammer could use an accent familiar to a targeted community to make a suspicious call sound considerably more trustworthy.

Scientists found a way to turn plastic bottles into cookies you can actually eat

Plastic bottles and cookies rarely show up in the same sentence, but a team of researchers just gave us a reason to talk about both together. According to Science Daily, scientists at Southern Illinois University Carbondale have engineered yeast that can turn waste from plastic bottles and old crop leftovers into real food ingredients and create cookies.

The work began as part of a NASA program exploring how astronauts might produce their own food during deep space missions, since resupply runs from Earth aren't exactly realistic that far out. The researchers' big insight was simple: plastic bottles are packed with carbon, and so, as it turns out, is food. That single connection became the foundation for everything that followed.
