Silk
-
For the first time, scientists have successfully produced full-length spider silk fibers using genetically modified silkworms. This silk has the potential to provide a scalable, sustainable and better-quality alternative to current synthetic fibers.
-
Current methods for repairing nerve injuries can be hit-and-miss. For the first time, researchers have combined two kinds of silk - from silkworms and spiders - to create a promising, biocompatible method of regenerating injured nerves.
-
Just like pharmaceuticals, banknotes and alcoholic beverages, the crop seeds sold to farmers are frequently counterfeits. MIT scientists have devised a method of spotting the fakes, by tagging genuine seeds with silk dots.
-
Nanofibers have recently been utilized in many applications, ranging from wound dressings to high-strength composite materials. Scientists have now developed a faster and simpler method of producing those fibers, which was inspired by the silkworm.
-
As one of the strongest materials known to science, spider silk regularly finds itself at the center of exciting engineering breakthroughs, but a new study involving a quick chemical bath could see silkworm silk outperform it.
-
Microplastics are a major environmental problem, but a new study could help cut out a decent chunk of them. Silk could be a biodegradable replacement for microbeads and particles that are often added to cosmetics, paints and other products.
-
When treating patients for certain conditions, it's important to monitor their blood oxygen levels. A new sub-dermal photosensitive sensor provides a new means of doing so, plus it could one day be used to measure other blood-borne substances.
-
An experimental new material could help rehabilitate the injured and allow the nonspeaking to "speak," among other potential uses. It's also highly elastic, electrically conductive and self-healing – and it's known as CareGum.
-
Adhesives that hold underwater are elusive, but could be useful for marine repairs or tissue healing. Researchers have now developed a new type of adhesive hydrogel that combines the underwater stickiness of mussels with the strength of spider silk.
-
Spider silk is one of nature’s most impressive materials, exhibiting impressive strength and toughness. Now, researchers at Washington University in St. Louis claim to have created an artificial version that can outperform some natural spider silks.
-
By mimicking the self-assembling microstructures that give spider silk its incredible strength, scientists have produced a plant-based film with the strength of common single-use plastics, offering a "vegan" eco-friendly alternative.
-
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.
