There are plenty of examples showing how traditional materials can be detrimental to works of art for instance wall paintings treated with acrylic

#Vest And Scarf Made From Spider Silk This silk scarf and vest have a nice drape
because they're made of super-strong transgenic spider silk. Functional and good-looking! Our favorite.
The clothes were woven from silk produced by silkworms with a spider gene engineered into them.
The resulting hybrid material is made up of less than 1 percent spider proteins yet it's 53 percent tougher than regular silk according to the research team five scientists from Japan's National Institute of Agrobiological
Scientists have known long spider-silk proteins are exceptionally strong. Dragline silk the stuff spiders use to make the spokes of their webs
and to dangle creepily from ceilings is five times stronger than an equal-sized thread of steel would be.
Researchers have thought about using spider silk for everything from surgical thread to bulletproof vests. There's no reason to make a cute scarf from spider silk of course
but the Japanese team members wanted to demonstrate they could harvest their product and feed it into the same machines silk factories use.
Why not get the silk directly from spiders instead of it putting it through a silkworm first?
Spiders don't make a lot of silk at once and they're cannibalistic so it's hard to maintain a spider farm.
Silkworms on the other hand have been domesticated over thousands of years. They produce voluminous silk cocoons and they're easy to raise indoors.
A silkworm that makes spider proteins could be a gentle little biological silk factory spinning out a super-strong product.
In recent years a number of labs have created genetically engineered silkworms that spin part-spider silk.
However this is the first time we've seen anybody produce and harvest enough of the material to weave it into something wearable.
and they performed strength tests on the raw silk. Eventually they made enough engineered silkworms that they were ready to kill the worms in their cocoons harvest the silk dye the silk threads
and knit the threads into cloth just like silk factories do. The researchers are now planning to try to raise their genetically engineered silkworms at commercial farms the Japan Times reports.

They formed silk scaffolds of different thicknesses (ranging from 2 to 5 micrometers) and stiffness combined with growth factors,
the researchers attached the silk scaffolds to a plastic framework to guide the growth of cells.
Next, endothelial primary cells (EPCS) were grown on one side of the silk scaffold and megakaryocytes were seeded on the other side.

#USDA Scientists, International Colleagues Sequence Upland cotton Genome U s. Department of agriculture (USDA) scientists and their partners have sequenced the genome of the world most widely cultivated and genetically complex species of cotton,
a milestone that will make it easier to address increasing threats to cotton by tapping into its natural defenses.
Sequencing the genome of Upland cotton (Gossypium hirsutum) will help breeders develop varieties of cotton that are equipped better to combat the pests,
Cotton growers have experienced a plateau in yields since the early 1990s and most commercial varieties lack genetic diversity, making cotton vulnerable to natural threats.
The findings will help researchers and breeders in the years ahead develop cotton varieties with improved fiber qualities, higher yields and more tolerance to heat, drought and diseases anticipated due to climate change.
Cotton is grown on 12 million acres in 17 states and is a $6 billion crop in the United states. here is untapped a vast
reservoir of genes in wild cotton plants that could offer us stronger and more effective defenses to the numerous challenges faced by cotton growers.
Sequencing of a genetic standard in cotton gives us the roadmap to identify and tap into that reservoir of genetic variability,
