Protons are subatomic particles with a positive electric charge. Proton translocation plays a significant role in natural phenomena and manmade technologies. But it remains challenging to control proton conduction and fabrication ...
Spider silk is a self-assembling biopolymer with hydrogen bonds underlying its chemical structure, yet despite weak chemical bonding it outperforms most materials relative to mechanical performance. The biopolymer is produced ...
Researchers have succeeded in creating a device that spins artificial spider silk that closely matches what spiders naturally produce. The artificial silk gland was able to re-create the complex molecular structure of silk ...

This week, we reported on spider silk synthesis without spiders, and how policymakers are pursuing a wish-based approach to a global economy under climate change—what the kids call "manifesting" a green-growth future. Plus, ...
Scientists in China have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests.

Researchers from Southwest University in China have constructed the entire chromosomal-scale genome assembly and complete spidroin gene set of the golden orb-weaving spider, Trichonephila clavata, known for its especially ...
The p53 protein protects our cells from cancer and is an interesting target for cancer treatments. The problem is, however, that it breaks down rapidly in the cell. Researchers at Karolinska Institutet in Sweden have now ...

A team of researchers affiliated with several institutions in the U.S. and Slovenia has found a previously unknown protein in the strongest known spider web material. In their paper published in the journal Communications ...
Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found.
