Growing human organs

...Science fiction has come to live... read more...
Scientist are growing human tissue and organ inside of animals for study and the possibility of creating donor parts that can be harvested from the animals. Nevada a farm contains a "flock of about 50 smelly sheep, many of them possessing partially human livers, hearts, brains and other organs."
Doctors have transplanted lab-grown tear ducts and an artery into patients. He has made an artificial nose he expects to transplant later this year in a man who lost his nose to skin cancer. Scientists would grow the structures needed for artery bypass procedures instead of taking a vein from another part the body. Researchers have been able to grow and implant three kinds of parts: flat tissues like skin, tubular structures like blood vessels, and hollow organs like stomachs and bladders. A lab-made ear scaffold would be far easier than the multiple procedures often necessary to carve an ear from their ribs. There are explosion of possibilities in regenerative medicine without requiring the controversial practice of extracting stem cells from embryos.
The next frontier includes solid organs, such as hearts, livers and kidneys. These structures are particularly complicated to build because they contain many different kinds of cell types and they require lots of blood vessels to carry fluids in and out.
Drugs have been developed to prevent the body from rejecting transplanted organs. One hope is to make donor organs obsolete, or at least far less necessary, eliminating long waiting lists for transplants. By using a patient's own cells, the new wave of regenerative medicine also circumvents ethical arguments and reduces the chance that recipients will reject their new parts.

Air

...It is here but you cannot see it... guess what?...Air
Air is the Earth's atmosphere. Air around us is a mixture of many gases and dust particles. It is the clear gas in which living things live and breathe. It has an indefinite shape and volume. It has no color or smell. It has mass and weight. It is a matter as it has mass and weight. Air creates atmosphere pressure. There is no air in the vacuum and cosmos. Air is a mixture of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. There is an average of about 1% water vapor. Animals need the oxygen in the air to live. In the human body, the lungs give oxygen to the blood, and give back carbon dioxide to the air. Plants need the carbon dioxide in the air to live. They give off oxygen that humans can breathe again. Wind is moving air. Air can be polluted by some gases (such as ozone and carbon monoxide), smoke, and ash. This pollution is one of the reasons for global warming, by causing the "greenhouse effect".
Other uses of air are as follows:
Aircraft use propellers to move air over a wing, which allows them to fly.
To fill air in balloons, tyres, cushions, inflatable toys
to dry washed clothes
To suck in dust in vacuum cleaner
to blow air
In wind mill
To cool hot objects
To burn fuel
to form bubbles
in piston

Car

...As a child I liked to play with toy cars...
A car is a wheeled, self-powered motor vehicle used for transportation. Cars are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. Cars are equipped with controls used for driving, parking, passenger comfort and safety and controlling a variety of lights. Cars are propelled by an internal combustion engine, fueled by deflagration of gasoline (petrol) or diesel. Fully autonomous vehicles, also known as driverless cars, already exist in prototype.

Pen Drive

...Guess what I have in my key chain? ... well a pen drive...
A USB flash drive, also known as pen drive is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable, and physically much smaller than an optical disc. Most weigh less than 30 grams. Drives of up to 512 gigabytes (GB) are available. Storage capacities as large as 2 TB are planned. Some allow up to 100,000 write/erase cycles. USB flash drives are often used for storage, data back-up and transfer of computer files. They are smaller, faster, have thousands of times more capacity. They are durable and reliable because they have no moving parts. They are immune to electromagnetic interference, and are unharmed by surface scratch. USB flash drives use the USB mass storage standard, supported natively by modern operating systems such as Windows, Linux, OS X and other Unix-like systems, as well as many BIOS boot ROMs. USB drives with USB 2.0 support can store more data and transfer faster than much larger optical disc drives like CD-RW or DVD-RW drives and can be read by many other systems such as the Xbox 360, PlayStation 3, DVD players and in a number of handheld devices such as smartphones and tablet computers, though the electronically similar SD card is better suited for those devices.
A flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic , metal, or rubberized case which can be carried in a pocket or on a key chain, for example. The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected. USB flash drives draw power from the computer via the USB connection. Some devices combine the functionality of a digital audio player with USB flash storage; they require a battery only when used to play music.
The uses of pendrive are as follows:
Personal data transport, Secure srorage of data, application and software files, Computer forensics and law enforcement, Updating motherboard firmware, Booting operating systems, Operating system installation, Backup, Audio players, Security Systems.
...The futuristic is that the trend would be pencil drive, refill drive and then dot drive...

Reduce harmful mobile radiation

1. When on a call, use a wired headset or speakerphone mode. Use a Bluetooth headset, which emits a smaller amount of radiation, only when talking. When not using the headset, keep it off your body.
2. Place the mobile phone away from your body when on a call.
3. Do not carry mobile phones in pockets of pants or in shirts. Use a belt holster designed to shield the body from radiation.
4. Avoid using a mobile phone in a moving car, train, bus, or in rural areas at some distance from a cell tower. Distance from a cell tower will increase the cellphone's radiation output.
5. Turn the mobile phone off when you don't need to use it.
6. Use a corded landline phone instead of a wireless phone, which also emits radiation.
7. Avoid using mobile phone inside of buildings, particularly those with steel structures, which increases the device's radiation output because signals are not as strong.
8. Do not allow children, whose bodies are more vulnerable to absorbing radiation, to sleep with a cellphone beneath their pillow or keep it at the bedside.
9. Do not allow children under 18 to use a mobile phone except in emergencies.
10. When making a call, do not hold the phone to your ear until after the person on the other line answers. The device emits more radiation before a call goes through.

Silver

Think of silver and what comes to your minds? Yes silver ornaments and silver ware and silver coins. But this is not all.
The other uses of silver are as follows:
Silver is used in the manufacture of crystalline solar photovoltaic panels. A mirror-like panel having a layer of silver that, when mounted on a building, acts like an air conditioner. Silver is used in water purifiers. The use of silver in photography, in the form of silver nitrate and silver halides Thermal or infrared telescopes use silver coated mirrors. Silver and silver alloys are used in the construction of high-quality musical wind instruments of many types.Flutes, in particular, are commonly constructed of silver alloy or silver plated. Silver stains are used in biology to increase the contrast and visibility of cells and organelles in microscopy. The medical uses of silver include its incorporation into wound dressings, and its use as an antibiotic coating in medical devices. filling for tooth in detistry. silver contacts in microelectronics. silver foil for sweet meats. silver coating.

Magnet

A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.
The uses of magnet are as follows:
Magnetic recording discs. Credit, debit, and automatic teller machine cards: All of these cards have a magnetic strip on one side. TV and computer screens containing a cathode ray tube employ an electromagnet to guide electrons to the screen. Speakers and microphones: Most speakers employ a permanent magnet and a current- carrying coil to convert electric energy (the signal) into mechanical energy (movement that creates the sound). A microphone has a magnet too. Electric guitars use magnetic pickups to transduce the vibration of guitar strings into electric current that can then be amplified. Electric motors and generators also have magnets. Hospitals use magnetic resonance imaging to spot problems in a patient's organs without invasive surgery. Chemists use nuclear magnetic resonance to characterize synthesized compounds. A compass (or mariner's compass) is a magnetized pointer free to align itself with a magnetic field, most commonly Earth's magnetic field. Vinyl magnetic art is not for the refrigerator anymore. Magnets have many uses in toys. M-tic uses magnetic rods connected to metal spheres for construction. Note the geodesic pyramidToys, magnets are often employed in children's toys, such as the Magnet Space Wheel and Levitron, to amusing effect.magnet in toy lift magnet in toy well Magnets can be used to make jewelry. Necklaces and bracelets can have a magnetic clasp, or may be constructed entirely from a linked series of magnets and ferrous beads. Magnets can pick up magnetic items (iron nails, staples, tacks, paper clips) Some screwdrivers are magnetized for this purpose. Magnets can be used in scrap and salvage operations to separate magnetic metals (iron, cobalt, and nickel) from non-magnetic metals. Magnetic levitation transport, or maglev, is a form of transportation that suspends, guides and propels vehicles (especially trains) through electromagnetic force. magnet to seal on the purse, magnet in pencil box cover, bits of magnetized papaer bits dance suspended in water in lamp shade, medicinal magnetic toe ring, magmet for magnetic massage, magnetic latch for the door, magnetic crane, magnetic films in giant magnetoresistance chip, magnetic gears to prevent slipping
