Do you know that Artificial skin has been developed?


Do you know that Artificial Human skin has been developed?

Human skin is a marvel of engineering.It is tough yet stretchy and piable and acts as an impermeable barrier against water loss,infection and Suns ultraviolet(UV) rays.With this range of properties,it is difficult material to make a clone or duplicate it!
             John .f. Burke,a surgeon at Massachusetts general hospital in united states,was looking for a reliable skin replacement for the treatment of burn victims.Skin is usually grafted from other parts of the patient's body,but in case where the burns cover 50% or more of the body,often there is not enough healthy skin to cover the damaged area.
            In 1970s Burke teamed up with Loannis V. Yannas,a chemistry professor at Massachusetts institute of technology(MIT) who was studying a stretchy protein called collagen that naturally occurs in an animals Tendon.Burke and Yannas combined collagen fibres from cowhides with long sugar molecules from shark cartilage to create a grid-like polymer membrane.They dried this membrane and stuck this onto a layer of viscious plastic.
           The two layers about as thick as a paper towel,offer a barrier against infection and dehydration while acting as a scaffold on which new skin can grow back,the artificial membrane breaks down naturally and can be peeled away.The newly skin formed doesn't have any mark or scar and looks like Normal skin,but lacks only sweat gland and hair follicles.
            In 1981,Burke and Yannis proved that their artificial skin worked on patients with 50 to 90 percent burns,vastly recovering their chances of recovery.
            Though it is not yet introduced in India,So we just need to wait for this boon.

That's all guys

DVD (DIGITAL VIDEO DISC)

The first proposals for a high-density CD were put forward in 1993, leading to the creation of two competing formats. Electronic powerhouses Sony and Philips led their collected investors forward with the MMCD format. going head to head with indusrry giants Toshiba, Masushita, and Time Warner's effort. the SD. Then, in 1995, a combined effort-known as the DVD-was off,cially announced and consequently developed by a consorrium of ten companies.

Who invented the Internet?

Advanced Research Project Agency develops the Internet. In 1963, Advanced Research Project Agency(ARPA) unit,set up by us defense department,began to build a computer network.The reason behind this was the fear of nuclear threat by Soviet Union,it aimed to link computers at different locations,so the researchers could share data electronically without having fixed route between them which made their system less vulnerable to attack--even nuclear ones.  The mechanism        Schematic diagram by Larry roberts Data was converted into telephone signals using a modem( Mo dulator- Dem odulator), Developed by AT&T in the late 1950s.In 1960s,key advances were made,including "packet switching" -- a system of packaging,labelling and routing data that enables it to be delivered across the network between machines.Paul baran proposed this system,which broke each message down into tiny chunks.This would be fired into the network,which would then route("swit...
