Donated Blood and Nitric Oxide

It is found that, patients who receive blood transfusions, have higher incidents of heart attacks, heart failure, stroke and even death.
This is because, the blood that has been donated to them, from the blood banks, might have lost, some of its life-saving properties, as an important gas nitric oxide, dissipates, as soon as the red blood cells leave the body of the donor.
Nitric oxide plays a key role, in transferring oxygen in the blood, to the tissues. If somehow, the level of nitric oxide is restored, at any point in the blood, the red blood cells will be again able to, open blood vessels and deliver oxygen to the tissues.
Researchers, are finding ways to safely add nitric oxide, back into banked blood, to improve its effectiveness.

Transparent Frog

This is a see-through frog, developed by Japanese researchers, as an alternative for dissections, that have become increasingly controversial in much of the world, particularly in schools.
In these frogs you can clearly observe the organs, blood vessels and eggs under the skin without performing dissections. You can watch organs of the frog over its entire life as you don't have to dissect it.
The researchers produced the creature from rare mutants of the Japanese brown frog or Rena japonica, whose backs are usually ochre or brown.
The research team, crossed two frogs, with recessive genes, through artificial insemination and the offspring looked normal ,due to the presence of more powerful genes. But crossing the offspring, led to a frog whose skin is transparent, from the tadpole stage.
The transparent frogs can also reproduce, with their offspring inheriting their parents traits, but their grandchildren die shortly after birth.

Battery that runs on sugars

Sony has developed a new battery, that uses sugar for producing electricity. Its outer case is made of a vegetable based plastic and it measures about 3.9cm in length. On testing, these batteries produced about 50 milliwatts of power, enough to run your music player.
In these batteries, electricity is produced by pouring sugar solution, into its unit. Inside, a chemical reaction occurs, in which, the enzymes break these sugar molecules to generate electricity.
Such batteries, that are derived from biomass (Biomass is a material derived from recently living organisms. It includes plants, animals and their by-products) are known as bio batteries. So, what Sony has developed, is a bio battery.

Secrets of an ancient astronomical device

A mysterious mechanism found in a 2,000-year-old Greek shipwreck may have been used to calculate the positions of planets, predict when eclipses were to occur, and do other astronomical chores.

The mechanism included sets of gears and moving hands to track astronomical cycles. Known as the Antikythera (pronounced an-tee-KITH-air-uh) mechanism, the device is about the size of a shoebox. When it was found underwater about 100 years ago, the mechanism was in poor shape. Its metal pieces had congealed into one mass, then broken into pieces. People who studied what was left of the mechanism suspected that it had something to do with astronomy. To find out more, researchers used advanced imaging methods, including X-ray computer tomography, to look inside the metal fragments and to check for ancient writing on the device. The computer tomography images of the mechanism, literally opened the device to see how it worked.

The mechanism had at least 30 bronze gears with as many as 225 teeth, likely all cut by hand. This fresh look provided clear evidence that the device could have been used to compute eclipses of the sun and moon. A lunar eclipse occurs when the moon passes into Earth's shadow, and a solar eclipse occurs when the moon passes between the sun and Earth. Scientists suspect that the mechanism was also able to show the motions of the planets. A user could pick a day in the future, and using some sort of crank, work out a planet's position on that date. The new images doubled the number of engravings that the scientists could read. These inscriptions revealed uses for the machine that were previously unknown.

With the added information, the researchers came up with a new model for how the mechanism operated.
The model takes into account 29 of the 30 known gears and adds five more that were probably there but never found.

The new picture adds a previously undiscovered spiral dial to the back of the device near the bottom. A hand moving around the dial could have pointed to eclipses over a period of 18 years. All these findings show that the Antikythera mechanism was perhaps 1,000 years ahead of anything else discovered from its time period.

The power of your subconscious mind

You can do anything that you want , through the power of your own subconscious mind. All you have to do is re-program it. Where you are in life, right now, is the perfect place for you. Your subconscious mind has followed your plans and desires to a tee. Whether you are rich, or poor, extremely successful, or struggling (you have never "failed" as long as you're alive), happy, or dissatisfied and miserable, THAT is where you directed your subconscious mind to take you.

Your subconscious has the power and knowledge of the universe, but it has no imagination, no direction of its own. It is like a magnificent ship capable of taking you anywhere in life's ocean. It even has its own, built-in navigator, but YOU are the MASTER. You have to plot your course, and it will follow your every command.
You may take exception to the first paragraph, particularly if your life is among the more negative of the examples. There lies the point in question.

The universe is in perfect balance, made up of "positive" and "negative" vibrations. If you seek, or even accept, the negative vibrations, that is what your subconscious projects, and what you, in turn, receive. Those who can only feel positive thoughts and project positive vibes, summon in powerful, positive strength to achieve anything.

Mind you, if you have suffered from "poor-meitus" for any length of time, or issued a great deal of negative vibes to yourself or others, this is hard to cure. The moment you try to put yourself on a "positive" course, you will find you have awakened a sleeping beast. Mr. Negative is a grasping, clinging monster who never wants to lose a slave. As you first begin feeling the results and rewards of a positive stance in all walks of your life, don't be surprised, or alarmed, by a series of negative occurrences. Just hang in there and, if you laugh at each weak attempt to discourage you, you will find your positive vibrations will always win out.

Everyone has a subconscious mind with the ability to do wonderful things for them. It is while developing in life, from childhood on, that so many negative messages can stunt its growth. From "don't touch that, you'll burn yourself", "get back or you'll fall", "look out, don't break that", to "you won't amount to much", "you'll never make it in that business", "you want to be a what?" - it's a wonder we ever make it to adulthood.

What your battered being has been most exposed to, or whatever compromises you have made in your development, can convince your subconscious mind that you want to be in a dull, unrewarding job, content to squeak by, at or near minimum wage.

Who do you really want to be? Where do you want to be? How wealthy do you want to be? Your birthright is to have health, wealth and happy relationships. Your subconscious mind can draw an abundance of each from your own treasure trove in the universe, if you just go about it the right way. How do you get the attention of your subconscious mind and make it accomplish these things for you?

Your mind can make miracles happen for you. You want to reach the top, enjoy life to the max? Don't ever say, "I wish I had done that." DO IT! It's easier than you think, through Hypnotherapy.

Facts about chewing gum

Most schools ban chewing gum, but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help boost your test scores. This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath. These enhanced gums are part of the growing number of foods and drinks that contain health-boosting ingredients. If you're already a gum fan, that's probably welcome news.

People have been chewing gum for thousands of years. Ancient Greeks, Mayas, and Native Americans, for example, chewed on the sap, or resin, of certain types of trees.

You know how gum is manufactured. Gum manufacturers start by mixing resin, wax, and a molecule called polyvinyl acetate to make a gum base. By varying the types and amounts of these ingredients, scientists can make thousands of formulations. Giant mixers then combine vats of melted gum base with powders, syrups, and sweeteners. Other machines roll the goo into sticks or press them into pellets. Packaging is the final step.
Americans chew about 1.8 pounds of gum per person each year, according to the U.S. Census Bureau. By showing that gum chewing can be healthy, companies that make and sell gum hope that we'll chew even more.
Many studies show that chewing gum after meals fights cavities by stimulating the production of saliva. Saliva helps wash away bacteria that damage our teeth. An ingredient called xylitol, which is added to some gums, provides an extra dose of cavity-fighting power. This is good for more than just the teeth. Good oral health decreases the risk of heart disease, diabetes, and other serious diseases.

Gum made with sugar can promote cavities. But some gums contain an ingredient that fights tooth decay. Chewing also stimulates production of saliva, which washes away cavity-causing bacteria. Some even say that, chewing gum might also be good for your brain. Some even say that chewing gum boosts the flow of blood to brains by up to 40 percent. Blood carries oxygen, which fuels brain cells.

While there are some who say that chewing gum perform better on memory tests. "It certainly makes sense,that increased blood flow would be related to increased alertness. Additional studies, with longer follow-up, are needed to confirm that chewing gum has benefits. So far, results of studies about memory have been mixed. Not all tests have had similarly encouraging results. What's more, many of the studies that show gum's benefits are funded by gum companies.

Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That's because the lining of our cheeks can absorb certain substances more quickly than our stomachs and intestines can.

Chewing a gumball or stick of gum that contains a medicine might help a person more than taking a tablet or a pill that contains the same medicine. Scientists found that people absorbed nearly three times as much of an allergy medicine when they chewed it in gum as when they swallowed it in tablet form. The researchers found that 40 percent of the medicine entered the bloodstream directly through the cheeks of the gum-chewing patients. That discovery could help other researchers develop medicine-containing gums that fight colds, relieve headaches, battle nervousness, and more. Scientists might even create antimicrobial gums that cure bad breath. Those projects may take years, but gum scientists have already had at least one recent success: They've created a gum that could help us stay awake. Its a caffeine-laced gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes. Chewing Stay Alert is like pouring coffee directly into your bloodstream. The military helped invent the product because it wants to be sure that soldiers stay awake during long, tiring night shifts. Studies show that soldiers who chew Stay Alert can function well for up to 72 hours without sleep. The gum is easy to transport and it's stable in cold and hot climates. Unlike a pill, it doesn't require water to swallow. Those qualities make it easy for soldiers to use. Well don't get excited about this new gum, Stay Alert is available only to the military. The manufacturer may one day offer it for sale to the public. People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product such as Stay Alert.
Some caffeine gums are already available in stores, but they haven't been as rigorously tested or regulated as Stay Alert has. Testing is essential because untested products might be harmful to health, or they simply might not do what they claim to do.

Chew with caution. Too much chewing can damage the jaw joint. And chewing too much of a gum that contains vitamins, caffeine, or a medicine could lead to an overdose. No matter how healthy gum chewing proves to be, it will never be a match for a healthy lifestyle.

Feel less pain

We can make ourself feel less pain. That's true. You know our brain controls our body, and our body affects our brain. Now, scientists have found a way to turn the system upside down. A new study suggests, people can use their minds to change the way their brains affect their bodies. In particular, by watching activity in a brain scan, people can train their brains to process pain differently and reduce the amount of pain that they feel. Researchers worked with 32 healthy volunteers, ages 18 to 37. These volunteers received a heat pulse to their legs. The heat pulses could vary in intensity. On a scale from one to 10 (with 10 being "the worst pain imaginable"), they had to report when the intensity of the pain that they felt was higher than 7. Using a brain-scanning machine called an fMRI scanner, the scientists were able to see that this level of pain sparked a lot of activity in a part of the brain called the rostral anterior cingulate cortex. Don't get afraid by the name. Its just a name given by the scientists to identify that part of the brain. Next, eight of the volunteers went through brain training. Scientists hooked them up to machines that allowed them to see what was going on in their own rostral anterior cingulate cortexes. An image of a flame grew when there was a lot of activity there and shrank when there was less. After 39 minutes of practice, the researchers found, volunteers were able to control the size of the flame and, hence, their pain levels, even with the same intensity of heat on their legs. Mental exercises, such as thinking about something besides the pain, seemed to help. The other 24 volunteers were also told to try to change the activity level in their rostral anterior cingulate cortexes, but they didn't get to see what was happening there. Sometimes, they were able to see brain activity in other parts of their brains or brain activity in other people's brains. Without direct feedback, though, they were unable to change the level of activity in the correct part of the brain or the amount of pain that they felt from the heat. These fMRI brain scans show various levels of activity (colors) in a part of the brain called the rostral anterior cingulate cortex.

In the final stages of their study, the scientists gave this type of brain training to eight people who suffer from chronic pain, which means they have recurring pain much of the time that gets in the way of their lives. By the end of the experiment, all of the patients reported, feeling less pain when activity in the rostral anterior cingulate cortex went down. Chronic-pain patients who practiced doing other types of feedback didn't gain the same benefits. Scientists have been struggling to understand pain for a long time. This new research might help,improve the lives of people who have to live with pain for long time.

Satellite multimedia for mobile phones

A new technology is being developed that would help satellite systems to broadcast digital multimedia content such as video, television programmes, radio, and data to mobile telephones and vehicle-borne receivers.
Such a development of mobile video services through satellites will provide content providers and operators, with alternative or complementary solutions, to terrestrial based networks and will bring the benefit of the universal coverage and broadcasting that satellites can provide.
High-power satellites in geostationary orbit have the ability to broadcast to large coverage areas and reach huge numbers of users. The proposed system will employ a mixture of satellites and Earth-based repeaters. Satellites ensure global coverage and repeaters make it possible to receive the signals inside buildings.
The system will be integrated into modern mobile telephone and vehicle-mounted receiver designs, at very low cost, making it ideal for the mass-market.
ESA’s technology support for this application area is being provided under several elements of its Advanced Research in Telecommunications Systems (ARTES) programme.

World's first Hybrid Train

Japan as always, is ahead than the rest in the field of technological development.A new hybrid train known as Kiha E200 was recently tested by the officials for its performance. This would be the first time that a diesel electric hybrid train would be put into commercial service. It is a two car train, equipped with a diesel engine, two electric motors under each of its cars and lithium ion batteries on the roof.The use of the diesel engine comes into picture, only when needed to climb a hill or if the batteries run low.
The batteries are recharged when the train slows down. After the power is switched off, the motors continue to turn for a while, and that energy - wasted in a non-hybrid train - is used to recharge the batteries.The Kiha E200, seats 46 and can hold 117 passengers, including the standees.You can see the word "hybrid" splashed in silver across its side, it is powered by its four electric motors. Besides the usual buttons and dials, the conductor also has a touch-panel monitor. Arrows show which way energy is flowing, connecting boxes that represent the engine, generator, motor and battery, busily changing direction every few minutes. Whether cars or trains, hybrids delicately balance the two sources of power, relying on a computer to minimise waste.
Data is being gathered by the EAST JAPAN RAILWAYS, on fuel consumption, which is expected to vary with different passenger loads, maintenance needs and whether the power holds up for heating in winter.
Cost still remains a hurdle. This hybrid train increases the fuel efficiency by 20 per cent and reduces emissions by up to 60 per cent.
This is Japan's latest entrant in the battle against global warming.

Know what Nanobattery is.

Before I write anything about Nanobattery, let me give you a brief introduction of what a capacitor is, it is an electrical device that can store energy in the electric field between a pair of closely-spaced conductors (called plates). When voltage is applied to the capacitor, electric charges of equal magnitude, but opposite polarity, build up on each plate. Thus a capacitor stores electric charge.
Now coming to the portable electronic devices such as notebooks, cellphones, PDAs and
many others, the major problem with all these devices are that they become useless
after the rechargeable batteries completely
discharge.Unfortunately, the devices themselves have known
huge developments, while their batteries remain a
source of discontent among users. Even the most
advanced laptop can only last for three hours if
relying only on the most advanced lithium
batteries.
NASA has a solution for everything.They came up with a brilliant idea of exploiting the technique used by biological molecules to self-assemble, to achieve the same result.
NASA used the ability of a protein called Ferritin, which contains iron, to perform the task of carrying either a positive or negative charge.
Ferritin has another remarkable ability, being able
to self-assemble more easily to form a homogeneous
layer. Such a ferritin layer could be covered with
another layer of the opposite charge, thus creating
a new capacitor that could store electric charge
between its layers, just like a battery.
The nanobattery has an overall thickness of only a few nanometers and its capacity could be increased even further by adding more layers of alternately
charged ferritin. According to NASA, the practical
applications of this concept would be robust,
stable and would also be easily and quickly
produced.
Well hats off to NASA.

Invest in Space Technology

Very few people know that the next industry area,
to experience an economic boom, will be the
exploration of space and space tourism.Yaa, there
are many people who are fed up of seeing the world
from inside and now want to see it from outside. Investing in space technology will be highly
profitable, if you are looking for future gains.
Recently, the first ESA Investment Forum took place
at the European Space Research and Technology
Centre in the Netherlands
. More than 100
participants from all over the world showed up and
expressed an interest for investments in the field.
The main aim of the Investment Forum was to
highlight the commercial benefits of satellite and
space technology in applications, on Earth and to
give potential investors an opportunity to meet
with a number of start-up companies using spin-offs
from space technology. Many new companies are
developing space related products and services,
proving that space will be the next big attraction
for people who want to invest in something new, or
simply don't know what to do with all the money.
New projects from a broad spectrum of technologies
look really promising, like sensors, navigation
data, satellite communication and imaging
technology. Many of these technologies have already
been transferred to applications on Earth where
they have generated countless business
opportunities.
So if you have some money and you have not decided
yet how to invest, or if you simply want a more
futuristic alternative, this looks like the right
spot. There are many industrial sectors who will
greatly benefit from applications developed in and
for the outer space, such as the automotive,
medical, offshore, security, energy, sports and
transport industries.
Space tourism is a refreshing alternative and even
if for the moment the pioneers paid around $20
million for a trip to the International Space
Station, future trips will get more affordable, so
in a few decades, travel agencies around the world
could advertise "space tours" and who knows, maybe
even on the Moon.

Know what VoIP is.

VoIP is a new addition to the world of internet. VoIP stands for Voice over Internet Protocol. It all began in early 1995, when few computer experts thought of sending voice signals over the net. In the beginning, the fledgling VoIP was not “duplex”, it means that, simultaneous conversations were not possible as with the telephone. It was much more like a walkie-talkie. Later in 1995 VocalTec Inc. released the first commercial Internet Phone Software and VoIP became duplex, simultaneous conversations were possible like over a telephone.
What happens in VoIP is little intersting, your voice data (your voice signals) is compressed with advanced algorithms into “packets” that are transmitted from your “client” (software or hardware server) via the Internet or Intranet to the recipient where the voice data packets are reassembled and decompressed into the intelligible sound of your voice. Data files of all types are sent much the same way, but aren’t compressed.
There are two primary standards for VoIP, these are Session Initiated Protocol and H.323. Most VoIP systems for business and home users are designed to be interoperable with PSTN (Public Switched Telephone Network), that’s your wired telephone system.
H.323 is an ITU Telecommunication Standardization Sector that defines the protocols to provide audio-visual communication sessions (video phones) on any packet network. It is currently implemented by various Internet real-time applications such as NetMeeting. It is also a part of the H.32x series of protocols, which addresses communications over Integrated Services Digital Network (ISDN), and PSTN. H.323 is commonly used in Voice over IP (VoIP, Internet Telephony, or IP Telephony) and Internet Protocol (IP)-based videoconferencing. It is similar to that of the Session Initiation Protocol (SIP) but with video capabilities.
Very recently Yahoo acquired voice over IP provider Dialpad Communications. Dialpad Communications software offerings are used by Yahoo in their voice communications products as well as instant messaging application. Dialpad is also going to be adding their PSTN feature to Yahoo Messenger (which uses the SIP standard), allowing users to make direct calls to landline or mobile phones from their PCs.

Know what DSL is.

DSL stands for Digital Subscriber Line. It is a service that makes the use of existing copper telephone wires for delivering data services at extremely fast speed rates. It does not hamper the existing telephone line. You can surf the Internet and talk on the phone, simultaneously.
DSL offers speeds that are around 5 to 25 times higher than a typical 56Kb dial-up connection. It is an always-on type of connection. This implies that websites would load quickly, downloads would be faster, buffering of videos would be fast and smooth and the domain of Online games would be illimitable.
Based on the types of service, DSL can be categorized into three divisions which are ASDL, IDSL and SDSL.
ADSL stands for Asymmetric Digital Subscriber Line. It offers download speed of 1.5 Mbps and upload speed of 384 K. In order to acquire a ADSL connection, your location has to be within 3 miles of your local telephone office. Also, a DSL router is needed for this type of connection.
IDSL is a ISDN Digital Subscriber Line service which requires an ISDN router. It provides a connection speed of 144 K. In this type of connection, distance is not a component to be considered.
SDSL means Symmetric Digital Subscriber Line. The speeds available under this type of DSL connection depends on the distance between your location and your local telephone office. The speed of downloads and uploads can go up to 1.1 Mbps.
There are few Advantages of DSL, no installation of new wires is required. DSL uses the present telephone line to connect to the Internet. It provides extremely fast connection. Depending on the offer, you would not even have to pay for the DSL modem installation charges, since it is provided free by some of the companies on selection of the appropriate plan. The download rate is much higher in DSL connections. Many business organizations have gained the benefits of DSL. A DSL connection is very secure.
The disadvantage of DSL is that the quality of your DSL connection depends on the distance between the DSL providers office and your location. Nearer you are, the better quality connection would you get. So, consumers located far from the local DSL office may face some trouble. DSL provide high speeds for downloading stuff but upload speeds are not that good.
The services provided through a cable modem can sometimes slow down or get hanged. It depends on the number of users accessing that particular service. But, in a DSL connection there is no such problem. The speed of DSL is consistent and high. This does not allow any kind of conjunction on the network. It provides more security than the cable modem connections. The popularity of DSL has risen to new heights which has resulted in disconnections and up gradations of the cable modem connections.

Understanding Stock Markets Basics

Learning about the stock market can be a long, painful and complicated task. In order to avoid all the migraines and all the mental disabilities that can be caused by such information overload, there are easy ways to learn all about it.
There are a few basic points that everyone needs to know in order to be able to achieve success. Obviously how things work in a stock market is one of them as well as types of stocks and bonds, which one's could bring more profit and other such boring pieces of information will be very useful to know. Let's start from, the beginning.
The stock market is a place where stocks, bonds, or other securities are bought and sold. When you buy stocks or shares in a company you gain part ownership in that company. In today’s world people buy stocks in order to gain dividends on money that they have invested. Some advantages of buying stocks over bank deposits; money-market funds or bonds are that stocks have a long historical track. Although the disadvantages of buying stocks are that the market fluctuates very often and the stocks are never guaranteed so you may loose all of the money you have invested. Before deciding on what type of stock you are going to purchase, you must determine what type of investor you are. There are two types of investors: technicians and fundamentalists. Technicians are investors that tend to buy and sell stocks very quickly. These investors are not interested in book values, dividends or earning although they study the price patterns of that certain stock. Fundamentalists are investors that look for long-term growth in a company. They consider such factors as earning, dividends and book values and are as interested in the price patterns because they are in for long term growth so they know that the market will fluctuate. When you are buying stocks there are three different types that you may choose from: penny stocks, growth stocks and blue chip stocks. Penny stocks are stocks from a company that has almost no chance of developing into a big company and the stocks are of very little monetary value. These stocks for example would be a chain of local pizza stores that would never make it into the big market of restaurants such as Pizza Hut but would do well in it’s local market. Growth stocks are companies that have a high potential to achieve great success, but they can also be very risky investments because they not are well established. An example of this type of company would one that invents a product that may make a big impact on the market similar to when air bags were invented their stocks probably rose drastically. These stocks would be the intermediate level in the purchasing of stocks. The highest level of stock purchasing is buying blue chip stocks. These stocks are of companies that are very well established and have almost no chance of its’ stocks dropping drastically. Some of these stocks would be of companies such as McDonald’s Corp., General Motors Corp., Coca-Cola Co., etc. Although blue chip stocks are the best stocks to invest in, they can also be very expensive limiting you to only buy a few of that companies shares. Often when the price of a stock plateaus, the company decided to split it’s stock. When this occurs you receive more stock for your money already invested. But when your companies stock splits two for one you get twice the amount of stock but the value of that stock depreciates by 50%. Reverse splitting means that the stock double in value although you only get to keep half the stocks you had before. Any way the stock may split you will not loose your money.
In any companies stock they are two different types of stocks you can buy: Common Stock and Preferred Stock. Common stock in a company shows you that you own a fraction of a company. Since common stock has a high potential for gain they are the last person to receive their dividends after those who own preferred stock. Preferred stock is sold to the public after all the common stock is sold. Companies who are going out of business have to pay out their preferred stock owners first because they have paid a higher premium for that same stock. Preferred stock owners only receive a fixed dividend payment making it the only drawback for people to purchase this type of stock. After you have decided what type of stock to purchase you must find a broker. This person will only take orders to buy and sell stock tickets. Every brokerage firm has two types of brokers. Stockbroker’s help by giving advise to on investing and by doing research on stocks. Discount brokers are the “middle man” of buying and selling stocks and do not research or give advise. After you find a broker, all that you have to do is give him or her a call when wanting to buy or sell your stock. After reading this, you probably have a huge headache. But I can assure you that, you have learned something new about the stock market that you did not know before. This was to inform 'not smart' people about the stock market. Most of the important things were covered in here but again it is all up to you to apply your skills, which many people are lacking.

Vista 'resume' bug plagues laptop users

A Microsoft engineer slammed Vista's ReadyBoost feature, as the source of a maddening bug, only to withdraw his charge the next day.
Whether or not ReadyBoost is to blame for the bug — which brings laptops to a crawl when resuming from sleep or hibernation mode — the problem remains a mystery for many who use Vista.
Microsoft engineer reports 'Vista suckage'
In a July 7 post entitled "Vista ReadyBoost Suckage & Vista resume sluggishness," Microsoft security software engineer Robert Hensing identified an apparent bug in which Vista can take several minutes to resume after a portable computer is put into sleep or hibernation mode.
"The disk just freaking thrashes and the HDD [hard disk drive] light stays on pretty much solid and the whole machine is pretty much unusable for about 5–8 minutes until the disk 'settles down,' " he wrote.
Nearly identical symptoms had been reported previously in blogs such as jkOnTheRun and Kevtris.
During the sluggish resume, Hensing noticed that Vista was writing several hundred megabyes per minute to the Flash drive he used for his ReadyBoost cache. ReadyBoost is a new Vista feature that uses a USB Flash drive as additional memory, as described by Microsoft. Hensing discovered that his notebook computer resumed Vista in just a few seconds if he removed the Flash drive during sleep mode.
Hensing theorizes that ReadyBoost needed to regenerate the AES128 encryption key on the Flash drive at the same time that it was restoring data from the hard disk. He went on to state that the problem was expected to be fixed in SP1, Vista's much-anticipated first service pack. His post was quickly picked up by Long Zheng, another victim of the bug, who covered the emerging story on his IStartedSomething blog.
Initial post disappears as confusion mounts
Within a few days, however, the Hensing post disappeared from the Internet. Long Zheng and other bloggers took note, and a short time after that, the Hensing post reappeared — minus the original negative headline and with the original text formatted with strikeover lines.
The new post reports that the problem seemed to disappear after letting Windows Update install some patches. Hensing recanted his original theory blaming ReadyBoost and promised an update when more information was available. Unfortunately for his readers, Hensing failed to identify a particular patch that solved the problem.
There's no shortage of proposed solutions in the blogosphere, though. For example, James Kendrick reported in his blog that he was able to solve the problem by implementing some Registry tweaks designed to turn off Vista's SuperFetch feature and use of virtual memory. Such changes are counterintuitive at best, since these features are specifically designed to improve Windows' performance. Nevertheless, "My disk thrashing has practically stopped," he reports. "It now only takes five seconds to go into standby and about the same to resume. Overall I'm finding the disk activity to be similar to Windows XP and I am very happy with the outcome."
Windows Secrets columnist Susan Bradley posted on her blog a collection of links to Microsoft hotfixes relating to Vista hibernation problems. These patches are expected to be rolled into Vista SP1, yet none of them precisely describes the symptoms reported here.
To date, Microsoft has not offered a clear, consistent explanation of the problem(s) behind the troubling laptop behavior. When asked about the situation, Microsoft representatives told me that they had no information to share at this time. Until they do, users are left to experiment with one of the word-of-mouth solutions proposed in various blog postings.
Problems such as this may explain why neither businesses nor consumers are in a hurry to upgrade to Vista, according to a report by Associated Press business writer Jessica Mintz. As she notes, "Gripes over what doesn't work with Vista continue, eclipsing positive buzz over the program's improved desktop search, graphics, and security."
