Dragon Silk
Dragon silk is a material created by Kraig Biocraft Laboratories of Ann Arbor, Michigan from genetically modified silkworms to create body armor. Dragon silk combines the elasticity and strength of spider silk. It has the tensile strength as high as 1.79 gigapascals (as much as 37%) and the elasticity above 38% exceeding the maximum reported features of the spider silk. It is reported that dragon silk is more flexible than the Monster silk and stronger than the "Big Red, recombinant spider silk designed for increased strength. Properties Mechanical properties Dragon silk has properties higher than that of any other fiber ever noticed. Tensile Strength In comparison, Dragon silk's tensile strength is higher than that of steel(450-2000 MPa's). In a report it is said that the strength of Dragon silk is as high as 1.79 GPa's which is 37% higher than the widely reported spider silk. Its tensile strength is higher than the "Big Red silk," which had been reported as the strongest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kraig Biocraft Laboratories
Kraig Biocraft Laboratories, Inc. is an American biotechnology company headquartered in Ann Arbor, Michigan. It develops and manufactures recombinant spider silks and other high-performance polymers using spider silk gene sequences. Their most notable fiber is dragon silk which has been demonstrated to be tougher than many fibers used in bullet proof vests. History Kim Kraig Thompson, a retired lawyer, invented the protein expression platform in 2002, which would become the basis for Kraig Lab's work with spider silk. He founded Kraig Biocraft Laboratories in April 2006 to develop and commercialize spider silks and other high-performance polymers gene and sequences using platform technology in combination with genetic engineering concepts. The original scientific work to reduce Thompson's invention to practice was performed in the biological laboratories of the University of Notre Dame. The University of Notre Dame was chosen in large part because the co-inventor of the Pig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ann Arbor, Michigan
Ann Arbor is a city in the U.S. state of Michigan and the county seat of Washtenaw County, Michigan, Washtenaw County. The 2020 United States census, 2020 census recorded its population to be 123,851. It is the principal city of the Ann Arbor List of metropolitan statistical areas, Metropolitan Statistical Area, which encompasses all of Washtenaw County. Ann Arbor is also included in the Metro Detroit, Greater Detroit Combined statistical area, Combined Statistical Area and the Great Lakes megalopolis, the most populated and largest Megaregions of the United States, megalopolis in North America. Ann Arbor is home to the University of Michigan. The university significantly shapes Ann Arbor's economy as it employs about 30,000 workers, including about 12,000 in the University of Michigan Health System, medical center. The city's economy is also centered on high technology, with several companies drawn to the area by the university's research and development infrastructure. Ann A ...

Spider Silk
Spider silk is a protein fibre spun by spiders. Spiders use their silk to make Spider web, webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to Ballooning (spider), float through the air, or to glide away from predators. Most spiders vary the thickness and stickiness of their silk for different uses. In some cases, spiders may even use silk as a source of food. While methods have been developed to collect silk from a spider by force, it is difficult to gather silk from many spiders compared to silk-spinning organisms such as Sericulture, silkworms. All spiders produce silk, and even in non-web building spiders, silk is intimately tied to courtship and mating. Silk produced by females provides a transmission channel for male vibratory courtship signals, while webs and draglines provide a substrate for female sex pheromones. O ...

Spiders
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Silk
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ( bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Engineering In The United States
The United States is the largest grower of commercial crops that have been genetically engineered in the world, but not without domestic and international opposition. Monsanto, based in Creve Coeur, Missouri in the United States, is the leading producer of genetically engineered seed; it sells 90% of the world's GE seeds. Legislation See Farmer Assurance Provision. (This bill is commonly referred to as the “Monsanto Protection Act” by its critics.) Lawsuits ''Foundation on Economic Trends v. Heckler'' In 1983, environmental groups and protestors delayed the field tests of the genetically modified ice-minus strain of ''P. syringae'' with legal challenge''Foundation on Economic Trends v. Heckler'', 756 F.2d 143 (D.C. Cir. 1985) ''Alliance for Bio-Integrity v. Shalala'' In this case, the plaintiff argued both for mandatory labeling on the basis of consumer demand, and that GMO foods should undergo the same testing requirements as food additives because they are "material ...
