Imagine spilling red wine or chocolate syrup on your shirt, only to watch it glide off as if nothing ever happened in the first place. Hogwash? No, it's called NeverWet.

Awhile back, I wrote about NeverWet, a superhydrophobic coating that can be applied to nearly any surface and repels liquids startlingly well. To bring NeverWet to the masses, developer Ross Nanotechnology licensed the product to Rust-Oleum, which recently started selling the spray for $19.97 at Home Depot.… Read more

Australia is known for its overly large bugs, like the up-to-20-inch Titan stick insect. But the country also has tiny insects, like the itsy-bitsy wheat wheevil. Researchers with Australia's national science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), are trying out a method of super-sizing insects through 3D printing.

Small, sometimes nearly microscopic, insects from the Australian National Insect Collection are run through a 3D-scanning system and then printed out at magnified sizes in titanium. Why would you want to do this other than to leave one on someone's seat as a prank? The bigger versions give scientists a better look at the insect's anatomy in order to learn more about their surface characteristics or determine gender. Plus, it's just plain cool.… Read more

Foiling facial recognition systems that identify people based on photographs may be as simple as wearing a special set of glasses equipped with near-infrared LEDs powered by a battery pack. The LEDs are arranged around the nose and eyes. The human eye can't pick up the near-infrared, but a camera sees it as bright light, enough to obscure the face and confuse facial recognition software.

Researchers with the National Institute of Informatics and Kogakuin University in Japan developed the special privacy visor to counteract photographs and facial recognition software that could invade privacy. Details on the glasses were released late last year, but a prototype got a public showing at a recent open house.… Read more

Are you up for a challenge? How about a Grand Challenge? NASA on Tuesday issued a Grand Challenge aimed at locating all asteroid threats to Earth and figuring out what to do about them.

It seems the asteroid threat has really picked up steam lately. We've had some close fly-bys. Some scientists have suggested nuking asteroids if they get too near. NASA has an initiative to lasso an asteroid for closer study. It's been asteroid fever around the planet lately.… Read more

Here on planet Earth we're used to flames -- whether from a candle or campfire -- reaching upward to the sky with slender limbs hungry for oxygen and driven by rising hot air. But in space, sans our planet's strong gravitational pull, flames are more likely to take the shape of eerie fireballs.

Within the flame of a regular candle wick, there's quite a bit going on. As the video below released this week by NASA explains, molecules from the wick are being cracked apart and vaporized by the flame, then combined with oxygen to produce light, heat, carbon dioxide, and water, as well as soot.

In recent years we've become quite familiar with how flames can extend and expand quickly in their greedy quest for more fuel and oxygen; witness countless western wildfires of the past decade. But researchers aboard the International Space Station have observed that flames in microgravity behave much differently, staying in a small spherical shape and letting oxygen molecules come to them.… Read more

Unfortunately, the Large Hadron Collider is too big to bring home and put on display in your living room. Scientist Sascha Mehlhase created a 4,500-piece Lego model of the collider back in 2011 at a cost of about $2,700. That was also too big for most people.

Now, he has created a smaller model of the ATLAS experiment, a particle physics experiment at the Large Hadron Collider, and put it up as a candidate for an official Lego kit.

The project is on Cuusoo, a site for Lego enthusiasts to share their models and attempt to gather 10,000 votes in order for Lego to consider making their creations as kits. Mehlhase's ATLAS currently has 5,756 supporters, so it has definitely caught the eyes of Lego builders.… Read more

Let's say you're a cat touring Paris, and you swing by the Place Vendome. What does it look like? Well, a lot like what humans see, it turns out, only much greener. That's because cats are dichromats and don't see the color red.

I viewed the Place Vendome from a feline perspective while scrolling around All Eyes on Paris, an interactive 3D digital simulation that shows the City of Light through the eyes of common critters.

Now on display at the Futur en Seine international digital festival in Paris, the project aims to teach about animal vision by letting you see a bit of the world as a cat, dog, bee, hawk, or rat would. And let me just say that rats don't have Paris anywhere near as gorgeous as they do when Pixar takes them there. … Read more

At first glance, it might not look as tricky as piloting a quadcopter just by thinking at it, but a project by artist Lisa Park has surprising depth. Eunoia -- Greek for "beautiful thinking" -- is all about the hidden power of the mind.

The performance itself consists of Park meditating, surrounded by flat 60-centimetre-diameter dishes of water mounted on speakers. As she meditates, she channels her thoughts into making the water ripple and leap, remaining completely still in the center.

On her head, she wears a Neurosky EEG headset -- the same device used in the Necomimi emotion-displaying cat ears. … Read more

Ever wanted to be a waterbender, or maybe Iceman (not to be confused with Mr. Cool Ice)? A trick to freeze water instantaneously won't actually make it so, but you'll feel pretty cool.

YouTube user Grant Thompson of Random Weekend Projects has posted a video that shows how it's done. You need some bottles of purified water, a clock, and a freezer. When you put the bottles of purified water in the freezer, the absence of impurities such as dust or microorganisms in the liquid means ice crystals have nothing to form around, so the water can reach temperatures below freezing without solidifying. … Read more
