Synthetic Blood is here!

Do you know that Synthetic Blood is developed?

What is synthetic blood?

PolyHeme,substitute for blood

Synthetic blood is a product that acts as a substitute for red blood cells,designed for the purpose of transporting oxygen and carbon dioxide around that body.
       The development of artificial blood is desirable for the problems associated with the blood transfusion,particularly the risk of transmitting viral diseases such as HIV and Hepatitis.There are also difficulties with transporting and storing blood,as well as a shortage of blood sober as the synthetic blood is kept in powder form.
       In 1956 Thomas chan,working on an undergraduate research project at McGill University,Montreal,created the first artificial blood cells.Turning his dormitory room into a makeshift laboratory,chan used improvised materials(including perfume atomiser) and cellulose nitrate solution (a material used to cover cuts and wounds) to make a permeable sack that could transport haemoglobin.Haemoglobin can be extracted from old blood done,cow's blood,plants and fungi.It is modified to ensure it is stable before being used in human body.
        Synthetic blood had not yet become an alternative for real blood,but it has been used apart from research.There are ethical questions about its use and weather people will accept artificial blood.Europe has explored haemoglobin-based oxygen carriers (HBOCs),wheareas the United States had focused on perfluorocarbons (PFCs), a Teflon-type group of synthetic liqiuds.But HBOCs and PFCs still lack two ingredients of real blood:White blood cells to fight infection and platelets to help blood clot.Finding a substitute that performs all the bloods functions still eludes scientists.

That's all guys

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...
