Squid-inspired stick-on camo to let future soldiers evade infrared

The solder of the future may be able to sneak into enemy-held locations and evade opposing forces by wearing disposable stick-on camo – based on squid biology – that renders them undetectable to night vision-enabling infrared cameras and sensors.

Although not yet ready for use, the technology has been presented by its inventors from the University of California at Irvine, who believe it has considerable potential for use in the field.

“Soldiers wear uniforms with the familiar green and brown camouflage patterns to blend into foliage during the day, but under low light and at night, they’re still vulnerable to infrared detection,” said lead researcher Dr Alon Gorodetsky.

“We’ve developed stickers for use as a thin, flexible layer of camo with the potential to take on a pattern that will better match the soldiers’ infrared reflectance to their background and hide them from active infrared visualization.”

With an appearance and texture similar to sticky tape, but coated with a reflective protein, the camo is designed to stick to the fabric camp uniforms of soldiers.

Known as “invisibility stickers”, they would be worn only when needed, and are designed to quickly be added or removed as required: the team envision soldiers carrying a roll of the camo with their kit, ready to be used at a moment’s notice.

Although not the most sophisticated solution to camouflage, the stickers are designed to be very cheap to produce, making them an appealing way for cash-strapped militaries to provide ground troops with infrared-proof camouflage.

“We’re going after something that’s inexpensive and completely disposable,” added Gorodetsky. “You take out this protein-coated tape, you use it quickly to make an appropriate camouflage pattern on the fly, then you take it off and throw it away.”

The protein coating the infrared-resistant surface is known as reflectin, and is also found in the camouflage-inducing cells of squid, called iridocytes.

The researchers saw squid biology as key to producing the infrared-resistance capabilities, and were able to identify the reflectin and reproduce it using bacteria.

However, finding a workable way to trigger the light-reflecting properties of reflectin on the camo has been more challenging.

The researchers first tried exposing the film to acetic acid vapors, which works in that it makes the film invisible to infrared cameras but would be a nightmare in the field.

“What we were doing was the equivalent of bathing the film in acetic acid vapors – essentially exposing it to concentrated vinegar,” said Gorodetsky. “That is not practical for real-life use.”

Now the researchers are working on a solution that stretches the material to make it infrared-proof, and also allows multiple stickers to respond in unison.

However, the team believe that the stickers could also be used to trap or release body heat in clothes if re-tuned to a different infrared wavelength, meaning this squid-inspired technology could form the climate-adapting clothing of tomorrow.

Robot takes first steps towards building artificial lifeforms

A robot equipped with sophisticated AI has successfully simulated the creation of artificial lifeforms, in a key first step towards the eventual goal of creating true artificial life.

The robot, which was developed by scientists at the University of Glasgow, was able to model the creation of artificial lifeforms using unstable oil-in-water droplets. These droplets effectively played the role of living cells, demonstrating the potential of future research to develop living cells based on building blocks that cannot be found in nature.

Significantly, the robot also successfully predicted their properties before they were created, even though this could not be achieved using conventional physical models.

The robot, which was designed by Glasgow University’s Regius Chair of Chemistry, Professor Lee Cronin, is driven by machine learning and the principles of evolution.

It has been developed to autonomously create oil-in-water droplets with a host of different chemical makeups and then use image recognition to assess their behaviour.

Using this information, the robot was able to engineer droplets to have different properties­. Those which were found to be desirable could then be recreated at any time, using a specific digital code.

“This work is exciting as it shows that we are able to use machine learning and a novel robotic platform to understand the system in ways that cannot be done using conventional laboratory methods, including the discovery of ‘swarm’ like group behaviour of the droplets, akin to flocking birds,” said Cronin.

“Achieving lifelike behaviours such as this are important in our mission to make new lifeforms, and these droplets may be considered ‘protocells’ – simplified models of living cells.”

The research, which is published today in the journal PNAS, is one of several research projects being undertaken by Cronin and his team within the field of artificial lifeforms.

While the overarching goal is moving towards the creation of lifeforms using new and unprecedented building blocks, the research may also have more immediate potential applications.

The team believes that their work could also have applications in several practical areas, including the development of new methods for drug delivery or even innovative materials with functional properties.

Las Vegas strip club employs robot strippers

A Las Vegas strip club has flown in robot strippers from London to 'perform' at the club during CES. Sapphire Las Vegas strip club managing partner Peter Feinstein said that he employed the robots because the demographics of CES have changed and the traditional female strippers aren’t enough to lure a crowd to the club anymore.

Scientists discover ice cliffs on Mars

Using images provided by the Mars Reconnaissance Orbiter, scientists have described how steep cliffs, up to 100 meters tall, made of what appears to be nearly pure ice indicate that large deposits of ice may also be located in nearby underground deposits. The discovery has been described as “very exciting” for potential human bases.
