It’s rare to see cosplay portraits without a Deadpool photobombing in the background.
Just in time for Halloween, our scientists are engineering one of the most intense phobias around.
Strictly speaking, the incredible bounce of water in these gifs above doesn’t have to do with being scared—last we checked, water was still pretty stoic—but the phenomenon is called hydrophobicity, literally a fear of water. Nanoscale cone structures across the material repel water with extreme prejudice, preventing any absorption and sending the little molecules on their merry way.
The slower droplets—captured here with a camera capable of shooting at 30,000 frames per second—bounce along the superhydrophobic (!) surface unimpeded, but the faster ones break apart in that gravity-defying dance. Moving this technology into car and aircraft windshields might ramp up visibility and also help self-clean by carrying along dirt particles.
While not quite as magical as the Impervius Charm, just consider that the scientists actually used a self-assembly fabrication process. You know, because billionths-of-a-meter structures just work better when they can build themselves.

How Ant Pupae Avoid Eviction
by Isabel Torres
For ant larvae and pupae, getting sick is a death sentence. When adult ants spot an infirm individual in their spotlessly clean nest, they simply chuck it out and leave it to die. This extreme “hygienic behavior,” as it’s technically called, is an effective way of containing disease outbreaks in crowded insect colonies.
But some pupae have worked out a way to avoid nest eviction—by growing inside bug-proof cocoons and dodging disease, reports a study published this week in BMC Evolutionary Biology.
Scientists have long wondered why in some ant species the pupae spin silk cocoons around their bodies, whereas in others the pupae are “naked.” In a few odd cases, ants can even swing both ways: In the same species, some pupae build cocoons, but others live happily without one. Or maybe not…

This Shoe is the Top Part of a 2 Part Shoe concept designed by Janina Alleyne & Modelled by INNER | LEAF. Janina Alleyne is a very talented Shoewear Design Student at De Montfort University in the UK. After advertising on Shapeways for a Shoe Modeller, INNER | LEAF were delighted to win the commission to model one of her designs. So impressed with the first model, Janina commissioned INNER | LEAF to do her entire range which included 3 shoes and a Hat.
Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) has created a set of bespoke titanium horseshoes for a Melbourne race horse using additive 3D printing. According to CSIRO, this is a first for horse racing and demonstrates the potential for the technology.
