The National Park Service is studying rapidly growing colonies of microorganisms that are blackening the dome of the Thomas Jefferson Memorial and other landmarks like the Lincoln Memorial and tombstones at the Congressional Cemetery. A multidisciplinary team of molecular biologists, conservators, and architects is analyzing the growth of the biofilm to hopefully identify a method to stop it that won't further damage the stone that the microbes have claimed as their home. One option is to battle the tiny beasts with lasers. From the National Park Service:
National Park Service officials recently began testing ten different chemical biocides in small patches affected by biofilm at the base of the Jefferson Memorial and will monitor how effective each one is in the coming days and weeks. They will also experiment with more non-traditional treatment options, including ozonated water and irradiation with lasers.

It’s not technically a fungus, or an animal, or a planet. It is, quite simply, an incomprehensibly bizarre yellow […]
Anton Hecht writes, "Slime Tango is a new game, the cello is optional. It is an inversion of tug of war, as here the players work together, while going apart. So is also an inversion of dance where people are close. The slime is stretched while following the dance steps, till it touches the floor, […]

We all know those gifts we get “for the kids,” the ones that parents are secretly more excited to open. Drones are a perfect example, but there’s a model out there that really doubles down on that appeal. Introducing the Space Fighter Building Block Drones, a series of space fighter drones that are a blast […]
The hardest part of web design can be nailing down the look. These days, even non-designers can easily spot a stale stock photo or lazily-made icon. What’s the solution? No matter what kind of artist you are, it’s always a good idea to widen your palette. And with more than a million vector images to […]
