1.0 INTRODUCTION: Spider silk has long been admired by scientists for its exceptional strength and elasticity, this admiration has led to many years of research to find a similar product that they can mass-produce. Due to spiders’ cannibalistic and territorial nature, alongside their inadequate production of silk, they are ill suited for commercial farming. This report will examine how scientists have genetically modified goats to produce large quantities of spider-like silk for use in industry,
Spider Silk - the Material of the Future Abstract: Spider silk is well known for its strength yet elastic nature, and for this reason scientists and engineers from a wide variety of fields have begun researching its structure and the possibility and methods of synthesizing spider silk for industrial use. However, extraction of silk from spiders is not cost effective, so most research is focused on synthesis of spider silk either chemically or using DNA recombinant technology. Although research
Bulletproof clothing is the most interesting thing I have ever seen in my life. There is not really a problem of bulletproof clothing besides it is very expensive to make it. It is very expensive just because of the materials. The materials are spider-silk, vectran and Kevlar. The history of bulletproof has been worn for thousands of years. Even the medieval Europe worn body armor. By the 1500’s, they changed the development of cannons and guns. Bulletproof in the encyclopedia means the protection
produce spider silk. Spider silk, specifically silk from the Gold Orb spider, is a very durable natural fiber. It is as strong as steel while being lighter and more flexible (1998 GM Gosline alt). This fiber, if it could be efficiently produced, could be used to produce everything from clothing to artificial tendons. However there are many factors that make spiders difficult to raise efficiently. For a start spiders are very territorial and if not given enough space will kill any other spiders in the
think that spiders and arachnids are synonyms with the same meaning and classifications. Through this piece, one will understand various differences and similarities between the two. Spiders are a member of the order, Araneae, class, Arachnids, and the phylum, Anthropods. Within the arachnid class lies much diversity and a few common traits. Spiders are grouped into this class as well as scorpions, ticks, mites, and many more organisms. The order, Araneae, is comprised of spiders. How do spiders
death. Black widow spiders are usually not aggressive. If disturbed, they will retreat to a corner of their web. These spiders are more aggressive if they are protecting an egg sac. The natural habitat of a black widow is outdoors, under rocks, brush or piles of debris. Indoors, these spiders can usually be found behind furniture, in storage boxes, etc. A black widow's eyes are on top and near the front of its head. They have 8 eyes, arranged in 2 rows of 4 each. Some spiders have better vision
through a latency of attack assay to determine their aggressiveness. The spiders were given 30 seconds and a cricket was dropped in and a measurement was taken of how long interaction occurred between the cricket and the spider. When testing food deprivation, the number of days that female spiders went without food varied and was paired in groups of 1, 3, and 5 days for routine feeding. It was predicted that the longer female spiders went without food, the hungrier they would be. When testing staged male
If I were invited into ‘room 101’ I would nominate the following things: chewing gum, spiders and pigeons. All of these things get on my nerves and deserve to go into room 101. The thing I dislike the most about chewing gum is where people leave it, on the bus, under tables and on the floor. It’s disgusting! Have you ever accidentally stepped on a piece of chewing gum just walking down the street? It gets stuck to your foot all day, you try and scrape it off, but it just isn’t budging. You then
destroy Othello. Rather than merely stating his desire to do this, Iago uses imagery based around a spider’s web. By doing so, ideas of creation, self utilization, and entrapment are brought into the plot concerning Othello. Iago likens himself to a spider, who spins a web from his own mind which will trap people, and cause them to serve his own needs. This passage shows the extent to which Iago foresees his own designs. Iago does not take an active role ... ... middle of paper ... ...y, and painful
been a debate on is The Spider Bite legend. This Legend has been told dating all the way back to the 1970’s and has had many variations of the story ever since. There has been extensive research throughout the years as to whether or not this legend is actually possible and although evidence has showed that this legend is most likely just a myth there have been stories in the news that have questioned the validity
Spiders My essay is on spiders. I have chosen a few spiders to report about. I also have some basic info about spiders in general. Spiders comprise a large, widespread group of carnivorous arthropods. They have eight legs, can produce silk, and usually have poison glands associated with fangs. More than 30,000 species of spiders are found on every continent except Antarctica in almost every kind of terrestrial habitat and a few aquatic ones as well. Spiders range in body size from about 0.5 mm
clothes, besides he should be able to discover which men in his kingdom are unfitted for their posts. Therefore he ordered to those two swindlers to make it ready for next month ceremony. Two swindlers asked such a huge amount of pure gold thread, fine silk and expensive cottons. They started their work in a separated room. They did put up two looms and all the time they just pretend to make such a fine stuff. The day and night they were busy with empty looms, but time to time they asked precious materials
Synthetic and natural fibers are the most essential part in clothes manufacturing. They make up the clothing we wear everyday. Fibers are made up of polymers, which are an arrangement of large molecules that are then made up of groups of even smaller molecules that are linked together to form a large chain structure. The smaller molecules are called monomers, and when they join together larger molecules are produced, making macromolecules (Bailey). Synthetic fibers are made up of polymers giving
I sigh as I try on yet another suit, “I’m sure this one will work, won’t it? Mother, please?” I cannot believe how many suits one person could need. All this work just for one ball… really it was just stupid. I had already tried on over 50 different ones and apparently none of them were, ‘Just right’! Honestly I’m starting to wonder if Mother is dragging this out just to embarrass me, I wouldn’t put it past her. However, I had to look perfect, after all this ball would decide a main component of
Engineering from the University of Illinois, Mr. Kilby decided to get his M.S. in the same field from the University of Wisconsin. He then began his career in Milwaukee in 1947, working in the Centralab Division of Globe Union Inc. “developing ceramic-base, silk-screen circuits for consumer electronic products.” 1958 was significant for Jack Kilby due to the fact that he began working in Dallas for Texas Instruments (TI) early that year. During the summer of that same year, using borrowed materials, Mr. Kilby
Borges and Bertolucci There are a number of differences between Bernardo Bertolucci's movie "The Spider Stratagem" and the story on which it is based, Jorge Louis Borges' "The Theme of The Traitor and The Hero;" however, overall Bertolucci does a pretty accurate portrayal of the essence, at least, of Borges' story. Besides changing the "setting" of the plot, there is also much more information relayed in the movie. This is very much due to that the story is simply a suggestive piece, while the
Scary Story I looked up at the black sky. I hadn't intended to be out this late. The sun had set, and the empty road ahead had no streetlights. I knew I was in for a dark journey home. I had decided that by traveling through the forest would be the quickest way home. Minutes passed, yet it seemed like hours and days. The farther I traveled into the forest, the darker it seemed to get. I was very had to even take a breath due to the stifling air. The only sound familiar to me was the quickening
Fallen Angels, by Walter Dean Myers, begins with the introduction of an African American 19-year-old boy who lives in Chicago. Recently he's joined the army and been assigned domestic work as he hoped for due to his bad leg and unreliable strength on it. Then, by accident of paperwork, he was eventually sent to Nam and put directly onto the field. He agreed to wait for his injury profile to catch up with him and that then he could return home. His mother at home is quite worried for him and also
the club or Zeus culture. The author uses a spider web to represent the club culture. “[T]he lines radiating out from the center” represent “divisions of work based on functions or products” (Handy p. 14). The most important lines however “are the encircling [lines], the ones that surround the spider in the middle, for these are the lines of power and influence, losing importance as they go farther from the center. The relationship with the spider matters more in this culture than does any formal
William Godwin's Attack on the Law Laws: We know what they are, and what they are worth! They are spider webs for the rich and mighty, steel chains for the poor and weak, fishing nets in the hands of government. - Proudhon1 On the surface, William Godwin's Caleb Williams (1794) is merely an entertaining murder mystery and detective story. The tale of an unfortunate servant who learns the truth of his master's past and flees for fear of his life, it has thrilled generations of readers
