Fuel Energizer






Definition:
Today's hydrocarbon fuels leave a natural deposit of carbon residue that clogs carburetor, fuel injector, leading to reduced efficiency and wasted fuel. Pinging, stalling, loss of horsepower and greatly decreased mileage on cars are very noticeable. The same is true of home heating units where improper combustion wasted fuel (gas) and cost, money in poor efficiency and repairs due to build-up.
Most fuels for internal combustion engine are liquid, fuels do not combust until they are vaporized and mixed with air. Most emission motor vehicle consists of unburned hydrocarbons, carbon monoxide and oxides of nitrogen. Unburned hydrocarbon and oxides of nitrogen react in the atmosphere and create smog. Smog is prime cause of eye and throat irritation, noxious smell, plat damage and decreased visibility. Oxides of nitrogen are also toxic.
Generally fuels for internal combustion engine is compound of molecules. Each molecule consists of a number of atoms made up of number of nucleus and electrons, which orbit their nucleus. Magnetic movements already exist in their molecules and they therefore already have positive and negative electrical charges. However these molecules have not been realigned, the fuel is not actively inter locked with oxygen during combustion, the fuel molecule or hydrocarbon chains must be ionized and realigned. The ionization and realignment is achieved through the application of magnetic field created by 'Fuel Energizer'

WHAT FUEL ENERGIZER DOES?

" More mileage (up to 28% increase) per liter due to 100% burning fuel.
" No fuel wastage.
" Increased pick-up.
" Reduced engine noise.
" Reduced smoke.
" Faster A/C cooling.
" Smooth running, long term maintenance free engine.
" 30% extra life for expensive catalytic converter.

HOW TO INSTALL?
Magnetizer Fuel Energizer (eg:- Neodymium super conductor - NSCM) is installed on cars, trucks immediately before carburetor or injector on fuel line. On home cooking gas system it is installed just before burner.

THE MAGNETIZER & HYDROCARBON FUEL
The simplest of hydrocarbons, methane, (CH4) is the major (90%) constituent of natural gas (fuel) and an important source of hydrogen. Its molecule is composed of one carbon atom and four hydrogen atoms, and is electrically neutral. From the energy point of view, the greatest amount of releasable energy lies in the hydrogen atom. Why? In octane (C8H18) the carbon content of the molecule is 84.2%. When combusted, the carbon portion of the molecule will generate 12,244 BTU (per pound of carbon). On the other hand, the hydrogen, which comprises only 15.8% of the molecular weight, will generate an amazing 9,801 BTU of heat per pound of hydrogen





Cylinder Deactivation



Definition
With alternatives to petrol engine being announced ever so often, we could be forgiven for thinking that the old favorite, the petrol engine, is on its last legs. But nothing could be further from the truth and the possibilities for developing the petrol engine are endless.
One of the most crucial jobs on the agenda is to find ways of reducing fuel consumptions, cutting emissions of the green house gas, co2, and also the toxic emissions which threaten air quality. One such fast emerging technology is cylinder deactivation.
CYLINDER DEACTIVATION
2.1 CONSIDERING DAIMLER CHRYSLER
By considering Daimler Chrysler's new 300cc car's powered by a revival of one of the greatest muscle car engine of all time, the V8 Hemi. This third generation grand master of funk has a capacity of 5.7litres snorts out 340 bhp with 54kgm torque and like all Hemis since the early 1950's has a pushrod valve train rather than a over head cam setup. But even though this Hemi can match its forebears on power 'its thirst for fuel has been cut by 10 to 20%. It is done by Chrysler's new multi displacement system (mds).
When using a lot of power, such as during acceleration, the hemi fires on all eight cylinders as usual. But around town or when cruising -even at motor way speeds or under gentle acceleration-the engine switches to frugal four cylinder mode.

Multi displacement system (mds) is activated at part throttle between 1000 rpm and 3000 rpm, when a hydraulically actuated catch in the special valve lifters trips to prevent the valves from opening. Hot gases are trapped in four of the eight cylinders, compressing and expanding like giant air springs as the engine turns over and keeping the cylinder warm. But as long as the valves remain closed, only four cylinders consume fuel instead of eight.
Engine efficiency is also improved because the four dormant cylinders are no longer working hard at sucking air into the engine, something that consumes a substantial amount of power. Although the average fuel saving is 10% ,under certain conditions it is a huge 20%.The transition from eight cylinders to four cylinders happens in just 40 mille seconds under the control of sophisticated engine management software which controls not just the multidisplacement system but also a drive-by-wire throttle.
CONSIDERING HONDA
IN Japan the 3.0 liter I-VTEC (intelligent VTEC) V6 of the Honda inspire can also deactivate tree of its first cylinders refinement being guaranteed by active hydraulic engine mounts to cancel out any vibration and active noise control with in the cabin to neutralize any unwanted booming. Honda's CIVIC IMA hybrid also make use of V TEC to deactivate three cylinders on the over run-again to reduce the pumping losses and cut fuel consumption

CONSIDERING GENERAL MOTORS
The actual idea of cylinder deactivation is not new. General Motors tried it in 1981 with the V-8-6-4 engine but through lack of sophisticated electronics drivability was awful. Now GM is returning to the idea again and is to soon launch Displacement on Demand (DOD} on itsVortecV 8's improving consumption by between 6 and 8%.

Top Powerful Car Engines

Top Ten Most Powerful Cars - They’ve Got The Power

Ferrari


This is a no-brainer. The 612 bhp Ferrari 599 GTB model is a super car that can speed to a formidable 205 miles per hour, revving up from zero to 62 mph in about 3.7 seconds. That’s right. Combining superior engineering, aerodynamics and electronics into this good looker, Ferrari has done it again with their style, producing a car with beauty and brains.

Lamborghini


The Lamborghini Murcielago LP640 comes in next. This car brings solid force at 640 bhp and can do 211 mph. Going from zero to 62 mph in 3.4 seconds, it is the typical Lamborghini functional design. Lamborghini’s engineers and designers have tweaked the engine, the electronics, gearbox, suspensions, brakes and exhaust system to produce this power packed car. The beauty of this aggressive car comes from its new front and rear bumpers. The diffuser on the rear bumper houses the exhaust system terminal. The left side has a huge opening to cool the oil radiator. On the right side, the area behind the air intake is shut off. Aerodynamic is one way to describe this powerful car.

Pagani Zonda


Stunning looking, the Pagani Zonda F CS, where the F honors the famous five-time Formula 1 Champ Fangio, is a 650 bhp car that can move at 214 mph, achieving 62 mph in 3.6 seconds. Practically handcrafted by Pagani, the Zonda F has a carbon-fiber body, chassis and interiors. Its interiors are beautifully finished in minute detail featuring vents on naked carbon-fibre stalks, a jeweled instrument panel and specially crafted embroidered leather instrument panel with aircraft style switches. Probably the most expensive open car in the world, the Zonda F is coveted by all car enthusiasts.

Mercedes Benz

The Mercedes-Benz McLaren SLR just bowls you over with its unique style and performance. This car uses carbon fiber for its chassis and packs in 650 bhp. The suspension configuration is tailor made and the car has a sporty interior. The 722 editions from Mercedes Benz acknowledge the victory of Brit racing legend Stirling Moss and Denis Jenkinson who used a Mercedes Benz 300 SLR, starting at 7.22 am in 1055. This car gives you a feeling of being on the racetrack with its ability to handle a maximum speed of 337 km/hour, light alloy wheels of 19 inch, a more rigid damper configuration and a lower body. The brake discs are larger, allowing for better braking.

GMG Apollo


One way to describe this beauty is very fast, exotic and powerful, with its 650 bhp reaching 62 mph in 3 seconds flat. This German power car has gull wing doors. This two-seater car gets its power from a 4.2 liter Audi V8 engine. The two-seater Apollo is powered by a 4.2-liter Audi V8 engine. It is capable of 650 bhp, which drives this car to race at 360 km per hour.

Saleen


Back in 2002, Saleen’s S7 was the only car in the US that could be legally driven with more than its 500 bhp and 500 lb-ft torque. This car has got rave reviews as the fastest American car in the world. Rather more popular for tuning Mustangs, Saleen has proved itself to be a super car manufacturer. Their S7 Twin Turbo features a whopping 750 bhp that lets you whiz to 60 mph in 2.8 seconds. This car features a structural sleek and aerodynamic carbon fiber body. The suspension is also of new design. Chassis tuning has a reworked shock valving front and rear. The main thing is the two turbochargers and a 7-liter V8.

Koenigsegg


Koenigsegg CCX or Competition Coupe X commemorates the tenth anniversary of the first ever CC model made in 1996. This 806 bhp car is an improvement over the CC model, with a new front bumper design and better brake cooling, fog lamps and US side position lights. The front lamps have also been redesigned. New air vents behind the front wheels to vent air from the cockpits. The CCX is now the roomiest car thanks to increased interior space. Koenigsegg engines are known to be unique and this car has a new engine management system.

Bugatti


The Bugatti Veyron boasts 987 bhp power and races to 62 mph in 2.5 seconds. Often considered the most powerful car ever, it has a low podium placing and went through various redesigns. This car can do 253 mph. There is another 1250 bhp version on the cards, expected to do 274 mph. That’s power.

Fuel Cells



Fuel Cell Basics
Through this website we are seeking historical materials relating to fuel cells. We have constructed the site to gather information from people already familiar with the technology–people such as inventors, researchers, manufacturers, electricians, and marketers. This Basics section presents a general overview of fuel cells for casual visitors.
What is a fuel cell?How do fuel cells       work?
Why can’t I go out and buy a fuel cell?
Different types of fuel cells.


What is a fuel cell?
A fuel cell is a device that generates electricity by a chemical reaction. Every fuel cell has two electrodes, one positive and one negative, called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes.
Every fuel cell also has an electrolyte, which carries electrically charged particles from one electrode to the other, and a catalyst, which speeds the reactions at the electrodes.
Hydrogen is the basic fuel, but fuel cells also require oxygen. One great appeal of fuel cells is that they generate electricity with very little pollution—much of the hydrogen and oxygen used in generating electricity ultimately combine to form a harmless byproduct, namely water.
One detail of terminology: a single fuel cell generates a tiny amount of direct current (DC) electricity. In practice, many fuel cells are usually assembled into a stack. Cell or stack, the principles are the same.

How do fuel cells work?
The purpose of a fuel cell is to produce an electrical current that can be directed outside the cell to do work, such as powering an electric motor or illuminating a light bulb or a city. Because of the way electricity behaves, this current returns to the fuel cell, completing an electrical circuit. The chemical reactions that produce this current are the key to how a fuel cell works.
There are several kinds of fuel cells, and each operates a bit differently. But in general terms, hydrogen atoms enter a fuel cell at the anode where a chemical reaction strips them of their electrons. The hydrogen atoms are now “ionized,” and carry a positive electrical charge. The negatively charged electrons provide the current through wires to do work. If alternating current (AC) is needed, the DC output of the fuel cell must be routed through a conversion device called an inverter.

Oxygen enters the fuel cell at the cathode and, in some cell types (like the one illustrated above), it there combines with electrons returning from the electrical circuit and hydrogen ions that have traveled through the electrolyte from the anode. In other cell types the oxygen picks up electrons and then travels through the electrolyte to the anode, where it combines with hydrogen ions.
The electrolyte plays a key role. It must permit only the appropriate ions to pass between the anode and cathode. If free electrons or other substances could travel through the electrolyte, they would disrupt the chemical reaction.
Whether they combine at anode or cathode, together hydrogen and oxygen form water, which drains from the cell. As long as a fuel cell is supplied with hydrogen and oxygen, it will generate electricity.
Even better, since fuel cells create electricity chemically, rather than by combustion, they are not subject to the thermodynamic laws that limit a conventional power plant (see “Carnot Limit” in the glossary). Therefore, fuel cells are more efficient in extracting energy from a fuel. Waste heat from some cells can also be harnessed, boosting system efficiency still further.

So why can’t I go out and buy a fuel cell?
The basic workings of a fuel cell may not be difficult to illustrate. But building inexpensive, efficient, reliable fuel cells is a far more complicated business.
Scientists and inventors have designed many different types and sizes of fuel cells in the search for greater efficiency, and the technical details of each kind vary. Many of the choices facing fuel cell developers are constrained by the choice of electrolyte. The design of electrodes, for example, and the materials used to make them depend on the electrolyte. Today, the main electrolyte types are alkali, molten carbonate, phosphoric acid, proton exchange membrane (PEM) and solid oxide. The first three are liquid electrolytes; the last two are solids.
The type of fuel also depends on the electrolyte. Some cells need pure hydrogen, and therefore demand extra equipment such as a “reformer” to purify the fuel. Other cells can tolerate some impurities, but might need higher temperatures to run efficiently. Liquid electrolytes circulate in some cells, which requires pumps. The type of electrolyte also dictates a cell’s operating temperature–“molten” carbonate cells run hot, just as the name implies.
Each type of fuel cell has advantages and drawbacks compared to the others, and none is yet cheap and efficient enough to widely replace traditional ways of generating power, such coal-fired, hydroelectric, or even nuclear power plants.
The following list describes the five main types of fuel cells. More detailed information can be found in those specific areas of this site.


Different types of fuel cells :
drawing of an Alkali fuel cell
Drawing of an alkali cell.
Alkali fuel cells operate on compressed hydrogen and oxygen. They generally use a solution of potassium hydroxide (chemically, KOH) in water as their electrolyte. Efficiency is about 70 percent, and operating temperature is 150 to 200 degrees C, (about 300 to 400 degrees F). Cell output ranges from 300 watts (W) to 5 kilowatts (kW). Alkali cells were used in Apollo spacecraft to provide both electricity and drinking water. They require pure hydrogen fuel, however, and their platinum electrode catalysts are expensive. And like any container filled with liquid, they can leak.
drawing of molten carbonate fuel cell
Drawing of a molten carbonate cell
Molten Carbonate fuel cells (MCFC) use high-temperature compounds of salt (like sodium or magnesium) carbonates (chemically, CO3) as the electrolyte. Efficiency ranges from 60 to 80 percent, and operating temperature is about 650 degrees C (1,200 degrees F). Units with output up to 2 megawatts (MW) have been constructed, and designs exist for units up to 100 MW. The high temperature limits damage from carbon monoxide "poisoning" of the cell and waste heat can be recycled to make additional electricity. Their nickel electrode-catalysts are inexpensive compared to the platinum used in other cells. But the high temperature also limits the materials and safe uses of MCFCs—they would probably be too hot for home use. Also, carbonate ions from the electrolyte are used up in the reactions, making it necessary to inject carbon dioxide to compensate.
Phosphoric Acid fuel cells (PAFC) use phosphoric acid as the electrolyte. Efficiency ranges from 40 to 80 percent, and operating temperature is between 150 to 200 degrees C (about 300 to 400 degrees F). Existing phosphoric acid cells have outputs up to 200 kW, and 11 MW units have been tested. PAFCs tolerate a carbon monoxide concentration of about 1.5 percent, which broadens the choice of fuels they can use. If gasoline is used, the sulfur must be removed. Platinum electrode-catalysts are needed, and internal parts must be able to withstand the corrosive acid.

Proton Exchange Membrane (PEM) fuel cells work with a polymer electrolyte in the form of a thin, permeable sheet. Efficiency is about 40 to 50 percent, and operating temperature is about 80 degrees C (about 175 degrees F). Cell outputs generally range from 50 to 250 kW. The solid, flexible electrolyte will not leak or crack, and these cells operate at a low enough temperature to make them suitable for homes and cars. But their fuels must be purified, and a platinum catalyst is used on both sides of the membrane, raising costs.
drawing of solid oxide fuel cell
Drawing of a solid oxide cell
Solid Oxide fuel cells (SOFC) use a hard, ceramic compound of metal (like calcium or zirconium) oxides (chemically, O2) as electrolyte. Efficiency is about 60 percent, and operating temperatures are about 1,000 degrees C (about 1,800 degrees F). Cells output is up to 100 kW. At such high temperatures a reformer is not required to extract hydrogen from the fuel, and waste heat can be recycled to make additional electricity. However, the high temperature limits applications of SOFC units and they tend to be rather large. While solid electrolytes cannot leak, they can crack.
More detailed information about each fuel cell type, including histories and current applications, can be found on their specific parts of this site. We have also provided a glossary of technical terms–a link is provided at the top of each technology page.

History Of Cars


Camille Jenatzy (1865 - 1913)

He Had 9 Lives, But A Practical Joke Proved Fatal
CAMILLE JENATZY, BORN IN 1865, was a Belgian civil engineer turned motor manufacturer who made his competition debut in 1898 at the controls of one of his own electric vehicles, in the Chanteloup hill-climb organised by La Prance Automobile.
Although heavy rain had affected the road surface, Jenatzy made the fastest time of the day, covering the 1800-metre course at an average speed of 17 mph. Three weeks after this, on 18th December, La Prance Automobile held a second speed trial, this time over a standing-start, two-kilometre course on a deserted stretch of level road at Acheres, to the west of Paris.
Jenatzy could not take part, and the event was won by the Count Gaston de Chasseloup-Laubat driving an electric  car built by Jeantaud, Jenatzy's manufacturing rival. The following day, Jenatzy wrote to Chasseloup-Laubat challenging him to a duel of speed, to be held within the month.
So, on the 17th January 1899, the two men met at Acheres. Jenatzy recorded a speed of 41.4 mph, but Chasseloup-Laubat clocked 43.7 mph, despite having the motor of his car burn out 200 yards from the finish. Ten days later, there was a return match. This time, Jenatzy reached 50mph over the flying kilometre, but Chasseloup-Laubat's motor burned out before he had even started. So his run was postponed until 4 March, when the Jeantaud achieved 57.6 mph.
The Jamais Contente
This was a phenomenal speed for the period, all the more remarkable for the fact that Chasseloup-Laubat's car was a standard touring vehicle fitted with a special body. Not in the least discouraged, Jenatzy set about building a new car with the express purpose of regaining the speed record. This was the famous Jamais Contente, a wonderful metal torpedo on wheels which was the first real purpose built racing car ever.
Its bullet-shaped body was made by Rheims & Auscher and was of partinium, a primitive aluminium alloy. To eliminate friction losses in the transmission, the electric motor was mounted directly on the driving axle. As a result, the car was fitted with the smallest wheels and tyres yet seen.
The First Vehicle To Exceed 100 Kph
The low, streamlined effect was somewhat nullified by" the fact that Jenatzy had to sit on top of the body, with only his nether regions inside the cockpit; nevertheless, after one false start, the car achieved his ambition of being the first vehicle to exceed 100 kph, his actual figure being 105 kph (65.8 mph). Not everyone was impressed, though. W. Worby Beaumont wrote in his massive Motor Vehicles and Motors: 'This is without doubt a higher speed than any other human being has ever travelled on roads, but it was only for about three-quarters of a mile that it was maintained. This vehicle was of no use in any way as a guide for any other class of vehicle'.
Because of the extremely limited range of the battery electric vehicle, especially if it was to have any sort of speed, Jenatzy soon turned his attention to petrol-electrics; he was also seen driving a Mors in three of the principal races of 1899 - the Tour de France, the Paris-St Malo and the Paris-Ostend - attracting public notice by his sporting effort in driving through the night in the Tour de France to make up for time lost.
In the 1900 Gordon Bennett, Jenatzy drove a Bolide petrol-electric of his own design, but lost his way and gave up in despair; the later Jenatzy petrol-electrics were equally unsuccessful, and his patent magnetic clutch, used by Pipe and Rochet-Schneider, enjoyed only a limited vogue. Jenatzy dropped out of motor sport during 1901, and his return in 1902 was hardly auspicious. During the Circuit des Ardennes, he had a terrible smash at the beginning of the second lap, the car going into one ditch and all four wheels into the other.
Le Diable Rouge
With his usual good fortune, he escaped with a few bruises. Because of his red hair and beard, and his flamboyant driving style, Jenatzy earned the nickname 'Le Diable Rouge' (The Red Devil), although there was nothing diabolic-apart from a liking for practical jokes-about his personality. In 1903, he transferred his allegiance to Mercedes, driving one of the. new 90 hp racers in the Paris-Madrid. Early in the race, he overtook 16 competitors, despite the unfavourable road conditions, and at Chatellerault, the big grey Mercedes was lying seventh. By Angoulerne, Jenatzy was third, and was being tipped as a possible winner but, at the top of the Petignac hill, he pulled up, with a mysterious fault in his engine. He eventually discovered, of all unlikely things, that the misfire was caused by a fly in the carburetter.

Interesting Facts


Individual dolphins identify themselves to new dolphins they meet


Dolphins are able to carry on multiple conversations simultaniously.
Dolphins apparently have a system of identifying themselves to each other similar to the way you and I use names.
Scientists have actually known since the 1960s that this system existed. Basically, each dolphin creates their own “signature” whistle when they’re very young. In studies of captive dolphins.

Nano particles in food, vitamins could harm human health

Billions of engineered nanoparticles in foods and pharmaceuticals are ingested by humans daily, and new Cornell research warns they may be more harmful to health than previously thought.
A research collaboration led by Michael Shuler, the Samuel B. Eckert Professor of Chemical Engineering and the James.

World’s tiniest lizards discovered in Madagascar


This little chameleon is one of four miniature lizards identified in Madagascar, adding to our growing list of amazingly teeny animals. The one on the match in this picture is a juvenile, but even the adults max out at 30 millimeters. They’re the smallest lizards in the world, and some of the smallest vertebrates found to date.
lizard
The Lilliputian lizard is near the lower limits of size in vertebrate animals. Learning about how these creatures live can put some constraints on animal morphology — if your species has eyes, a backbone and a brain, there’s likely a limit to how little you can get. A different group of field biologists just announced the world’s smallest frog, and they claim it is the smallest vertebrate in the world, knocking a tiny Indonesian fish off the pedestal of puniness.
The chameleons are related to other Madagascan lizards, but DNA analysis showed they have enough genetic differences to count as distinct species, according to the researchers who found them, led by Frank Glaw of the Zoological State Collection of Munich. The animals live in leafy undergrowth in Madagascan forests.

Nano Bots

Can Humanity Unlock Eternal Life Through Nanotechnology?

Nanobot
Nano Bot
This is actually quite a common question among the science and technology community in academia. And for now, the answer remains to be seen. We are just starting to see exponential progression with new innovations and breakthroughs in science and technology. The past 100 years of “Innovation” are not even worth mentioning when you compare past innovations to recent progression and breakthroughs.
Within the past decade, scientists and researchers from all over the world have been developing mind-blowing creative inventions, conducting research that will better humanity, and so much more. The time has finally come, where we have started to see some real traction of progress towards a future without death.
The possibilities for an anti-aging and anti-disease cure is overwhelming, and very much expected among the science and technology community. With recent breakthroughs in nano-technology, we have seen a glimpse of the future. This has not been a surprise to most scientists, but rather, expected.
 If you are not familiar with nanobots, let me fill you in on what they are and how they will change the world. Nanobots are micro-robots that have a wide array of purposes, especially helpful when used in the field of medicine. These little robots are being researched, developed, and used for all sorts of different medical purposes.
A good example of a nanobot’s use in medicine: UCLA has been working on a diamond nanobot which is injected into your bloodstream and searches for cancer cells and tumors. If a nanobot is able to find anything, it can absorb and completely remove the cancer cells and/or tumors. That is just a small example of what they are being used for today. Ideally, we want nanobots to become one with our body, forever protecting our flawed biological body from age and disease.


It remains the truth that humanity does 
not have a cure for aging or death, but 
with every step we take, every year that passes, we find ourselves with much better tools and knowledge than ever before. That, my friends, is the game-changer.










Applications :
1. Nanobots
Doctors will use “smart bomb” nanobots — atom-sized particles so small they’re invisible to many microscopes — to destroy deadly cancer tumors.
Already research has shown that gold-plated nanospheres — tiny ballshaped particles — can seek out and get inside cancer cells. They then can be made to “cook” and kill the cancer when they’re zapped with infra-red light to heat them up.
This all happens without any destruction to the surrounding healthy cells.
“This technique is very promising and exciting,” says Dr. Jin Zhang, professor of chemistry and biochemistry at the University of California in Santa Cruz, who came up with the treatment. “It’s basically like putting a cancer cell in hot water and boiling it to death.
“The more heat the metal nanospheres generate, the better.”
In the coming years, it is expected that more advanced nanobots will be sent on medical missions inside the body, where they’ll be able to replace inherited genes that cause genetic diseases. Down the road, they potentially could erase the damage and mutations that lead to human aging — keeping our bodies young and healthy.
Hiemstra, a consultant to major companies and government agencies on future trends, says the time is right: “This is one of the most exciting areas of medical research right now.”
2. Cure for the Common Cold and HIV
It could be the greatest medical discovery since penicillin — a do-it-all drug that can cure every virus from the common cold to HIV.
Researchers at MIT created the drug, called DRACO, which tracks down infected cells and makes them self-destruct.
They say its hit list also includes flu, polio, stomach bugs, deadly dengue fever, measles, cold sores, and rabies. “It’s certainly possible that there’s some virus that we aren’t able to treat, but we haven’t found it yet,” says lead researcher Todd Rider.  “We hope that this will revolutionize the treatment of viral infections.”
In lab tests DRACO has killed 15 viruses and saved the lives of test mice given a dose of flu that should have killed them. Incredibly, it works so quickly that if taken early enough, it should stop any symptoms from appearing. Human testing is expected to begin soon.

3. No More Transplant Waiting Lists

Scientists will grow new organs to replace diseased and damaged ones, thanks to incredible advances in regenerative medicine, an offshoot of bioengineering.
Bladders have been grown in a laboratory and successfully implanted into patients.
Soon, using tissue from the patient’s own existing organ and synthetic materials, doctors will be able to regenerate cells for skin, bone, cartilage, muscle, marrow, and other body parts.
It won’t just mean dramatic improvements in medical care for millions — it’ll save millions in medical costs. And it will mean an end to the long wait for donor organs.
4. Gene Therapy to Cure Cancer
Exciting breakthroughs in boosting the body’s immune system through gene therapy mean scientists will be able to tweak the body’s own defense mechanism to fight off a range of deadly cancers. A team from the University of Pennsylvania has shown they can genetically engineer a patient’s T cells — a type of white blood cell — to successfully attack cancer cells in advanced cases of a common type of leukemia.
Astonishingly, the therapy was so powerful, tumors were destroyed within three weeks, says Dr. Carl June, who’s leading the research. Now they hope they’ll be able to use the same treatment for many other cancers, including breast and colon. It’s been hailed as a huge advance.
5. Alzheimer’s
Scientists are confident that in the next decade they’ll develop treatments that will be able to stop Alzheimer’s disease in its tracks before it causes irreversible brain damage.
They have come up with molecules that can attack and destroy harmful proteins that build up in sufferers’ brains. These proteins can kill nerves that cause the symptoms of dementia such as memory loss and confusion.
Professor David Allsop, of Lancaster University in England — who’s heading the research — is also working on a method of diagnosing Alzheimer’s before symptoms appear. He’s dedicating his work to his grandfather, who suffered from the disease.
6. Stroke
For the first time, stroke victims will regain movement of paralyzed limbs, thanks to a simple nasal spray.
Biologists at the University of California, Irvine, have come up with a groundbreaking treatment using a natural protein called TGF alpha, which plays a role in tissue formation.
Studies found it can restore 99 percent of movement in rats if applied to the brains after a debilitating stroke. Human trials are now in the offing.
“TGF alpha has been shown to repair damage long after a stroke,” James Fallon, psychiatry and human behavior professor and senior co-author of the studies says. “We believe this same therapy will be effective in Parkinson’s and a number of other brain injuries and diseases. The potential for using this therapy in humans is very exciting.”
7. Blood Test to Predict Your Medical Future
“Ten years from now a simple blood test will be able to predict the future health of every major organ,” says Hiemstra.
Patients will then be able to take steps to prevent the onset of health problems. It will be commonplace to have a bad combination of genes repaired to avoid disease.
“This will result in much greater longevity,” adds Hiemstra. “We’ll have a lot more healthy 100-year-olds.”
