Silk

As useful a material as leather is, it isn’t too environmentally friendly. Now, engineers at Tufts University have created a new leather-like material out of silk, which can be 3D printed into shape and easily recycled into new products as needed.

Along with its use in clothing, silk also shows promise for use in products ranging from surgical sutures to seed coverings. Scientists have recently devised a method of making the material stronger, by altering the diet of silkworms.

Nanofibers have found use in numerous applications, ranging from lightweight car parts to high-strength materials. Now, thanks to a new understanding of a certain group of spiders, they may soon be easier to work with.

It’s no secret that spider silk is one of nature’s most incredible materials. Now scientists have discovered a weird new ability. A team led by MIT has found that when exposed to a certain level of humidity, spider silk suddenly shrinks and twists, which could make it useful in artificial muscles.

Strong as steel and tougher than Kevlar, spider silk is one of nature’s most impressive materials. Researchers from Washington University in St. Louis have now engineered bacteria to produce biosynthetic spider silk that they say performs as well as the real stuff.

Spider silk has long held the title of strongest natural biomaterial. Now, researchers at the KTH Royal Institute of Technology have developed a new biomaterial out of wood nanofibers that steals the strength record.

Spider silk is among the strongest known materials. While some researchers are pursuing synthetic spider silk, scientists at MIT have taken another approach … they've devised a method of using silkworm silk to produce fibers that are almost as stiff as spider silk.

​Natural spider silk is already amazingly strong stuff, plus scientists have developed synthetic versions of the material. Now, however, researchers have split the difference – they've created silk that comes from spiders, but that has added man-made ingredients which give it extra strength.

​Silk may be strong, elastic and biodegradable, but unfortunately it's also expensive. With that in mind, scientists recently set out to produce lower-cost artificial silk. They've already succeeded in producing small quantities, using whey protein.

Lightweight and extremely strong, spider silk is ideal for use in many applications. Unfortunately, large numbers of spiders are hard to handle and produce very little silk individually. Now researchers have created a prototype process to spin silk thread grown by bacteria on a large scale.

Scientists say they've devised a way to create "programmable" silk-based forms that have a variety of optical, chemical or biological functions. Imagine pins or other mechanical components that change color when they near a breaking point, or solids that can deliver drugs, among other possible uses.

Like other automakers around the world, Lexus is gearing up for the 2016 Paris Motor Show. Along with a world-premiere crossover concept, Lexus will reveal a very different kind of concept: a web-like driver's seat crafted from synthetic spider silk.
