The Correct Way To Drink Water



Our bodies are made up of mostly water. Just look at the facts: The brain contains 74% water, blood contains 83% water, lean muscle has 75% and bone has 22% water.. Experts agree that water is one of the most powerful forms of treatment. So how come most people don't drink enough water?

10 Health Benefits of Water:

1. Water prevents kidney stones. The most common cause of kidney stones is not drinking enough water. Since water dissolves the substances that form stones in the urine, drinking 12 glasses daily helps treat kidney stones.

2. Water treats urinary tract infection. The more water you drink, the more you will urinate. "Drinking lots of water will help flush out harmful bacteria from your bladder," says Medical City kidney specialist Dr. Roberto Tanchanco.

3. Water helps patients with diarrhea by preventing dehydration. As a first-aid for diarrhea, you can make your own oral rehydration solution at home. Mix a glass of water with 2 teaspoons sugar and ¼ teaspoon salt, and drink as much as you can tolerate. This is similar to the dextrose solution in the hospital.

4. Water helps reduce fever. For symptoms of flu, water can help lower your body temperature when you urinate the "heat" out of your body. If you're sick, drink more water for you to recover faster.

5. Water helps treat cough and colds, sore throat, and respiratory infections. Water helps loosen sticky phlegm. A respected lung specialist told me that some mucolytics out there are just as beneficial as drinking lots of water.

6. Water reduces heartburn. Taking 2-3 gulps of water every 20 minutes or so can help flush the stomach acid away. Bananas and water are effective alternatives to taking antacids. Try it.

7. Water prevents constipation and its complications. Too little water can harden the stools and lead to hemorrhoids and diverticulosis, a disease of the large bowel. Drink water and eat lots of vegetables to soften your stools.

8. Water keeps you alert and energetic. If you're dehydrated, your blood is literally thicker. This makes it harder for the blood to circulate. As a result, the brain can become less active and you can feel confused and fatigued. Some studies also show that water may help cure migraine headaches.

9. Water helps reduce weight. By drinking a glass or two of water before a meal, you will lessen the amount of food you can take in order to feel full. Water has zero calories and will not make you fat.

10. Water keeps your skin soft and radiant. Just as a dehydrated person will have deep-set eyes and wrinkled skin, so will a fully hydrated person exhibit a normal and beautiful skin tone.


The Correct Way To Drink Water:

1. Drink water when you wake up. Your body loses water while you sleep, so drink a glass before you go to sleep, and another glass when you wake up. You are naturally thirsty or dehydrated in the morning. Drinking water in the morning helps flush out the toxins that have accumulated all night.

2. Drink 8 to 12 glasses a day. According to the Mayo Clinic, a 120-pound individual needs 8 cups of water a day, while a 190-pound person would require 12 cups daily. Dr. Robert Tanchanco says that we should monitor our urine color and keep it on the light side. However, drink only a maximum of 16 glasses a day, and not more.

3. Drink little by little throughout the day. It is preferable to sip water throughout the day rather than to drink two glasses all at once. This will lessen the stress on the heart (especially if you have heart disease) and give your body more time to absorb it.

4. Don't wait until you're thirsty to drink water. By the time you feel thirsty, you're probably already 2 glasses below your normal water needs. Elderly people are also less sensitive to the body's need for water.

5. Drink water, not soft drinks, alcohol or coffee. Some experts believe that tea, sodas and coffee can be potentially dehydrating. Moreover, the high phosphorus and sugar content in cola drinks can lead to conditions like osteoporosis and diabetes. One study shows that adults who drank six cups of coffee daily experienced mild dehydration. Drinking alcohol is much worse because it actually dehydrates you by making you urinate a lot.

6. Train children to drink water. Set a good example to your kids and drink water together. Make sure that children drink enough water when they're active. Pack a large bottled water in their lunch box.

7. Drink more when it's hot. People living in hot climates like the Philippines need to drink more water. They are more prone to develop kidney stones compared to those living in cooler regions. 8. Drink more as you exercise. When you exercise, you need to drink more water to compensate for fluid loss. Go for an extra 500 ml of water for a 30-minute to 1-hour exercise. Eating a banana also helps keep your potassium up.

9. Drink more when you're sick. Even though you don't feel like it, you really need to drink more water to help your body recover from various infections. If you're dehydrated, you'll feel much worse.

10. Drink more if you're pregnant. Women who are expecting or breast-feeding need additional fluids to stay hydrated. The Institute of Medicine recommends that pregnant women drink 10 cups of fluids daily and women who breast-feed take in about 13 cups of fluids a day.

Aliens may exist but contact would hurt: Hawking


LONDON (AFP) – Aliens may exist but mankind should avoid contact with them as the consequences could be devastating, British scientist Stephen Hawking has warned.
"If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," said the astrophysicist in a new television series, according to British media reports.
The programmes depict an imagined universe featuring alien life forms in huge spaceships on the hunt for resources after draining their own planet dry.
"Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach," warned Hawking.
The doomsday scenario is suggested in the series "Into the Universe with Stephen Hawking" on the Discovery Channel, which began airing in the United States on Sunday.
On the probability of alien life existing, he says: "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.
"The real challenge is to work out what aliens might actually be like."
Glowing squid-like creatures, herds of herbivores that can hang onto a cliff face and bright yellow predators that kill their prey with stinging tails are among the creatures that stalk the scientist's fantastical cosmos.
Mankind has already made a number of attempts to contact extraterrestrial civilisations.
In 2008, American space agency NASA beamed the Beatles song "Across the Universe" into deep space to send a message of peace to any alien that happens to be in the region of Polaris -- also known as the North Star -- in 2439.
But the history of humanity's efforts to contact aliens stretches back some years.
The US probes Pioneer 10 and 11 were launched in 1972 and 1973 bearing plaques of a naked man and woman and symbols seeking to convey the positions of the Earth and the Sun.
Voyager 1 and 2, launched in 1977, each carry a gold-plated copper phonogram disk with recordings of sounds and images on Earth.

Your Mind Will Control TVs and Phones !


When I was a kid, my dad used me as his remote control. I, or one of my brothers, would at his request, turn the dial on the television -- click, click, click -- to the desired station.
Soon we could all be changing channels with our minds. Researchers in Europe and Japan are developing thought-controlled consumer electronics that will allow us to play games, push buttons and send text messages just by thinking about it.
Last month at the annual CeBit conference in Hanover, Germany, researchers from the Berlin Institute of Technology demonstrated a pinball machine game controlled by Electroencephalography, or EEG, technology.
And yesterday, the Nikkei daily announced a collaboration between Japanese corporations and universities including Toyota, Honda, Hitachi, the National Institute of Information and Communications Technology, Osaka University and the Advanced Telecommunications Research Institute International to develop similar technology that in addition to thought-controlled games and phones, would develop car navigation systems that search for restaurants when the driver thinks of eating and central air units that cool down or heat up when the person thinks they feel to warm or cold.

Alaska dog honored for leading troopers to fire


ANCHORAGE, Alaska – Buddy the German shepherd was hailed Friday as a hero for guiding Alaska State Troopers through winding back roads to a fire at his owners' workshop.
"Buddy is an untrained dog who for some reason recognized the severity of the situation and acted valiantly in getting help for his family," Col. Audie Holloway, head of the troopers, said Friday at a ceremony for the 5-year-old dog, who stood quietly before an adoring crowd.
Buddy, whose good deed was caught on a patrol car's dashcam video, received a stainless steel dog bowl engraved with words of appreciation from troopers for his "diligence and assistance."
Buddy also received a big rawhide bone, and his human family got a framed letter documenting his efforts.
"He's my hero," owner Ben Heinrichs said, his voice breaking. "If it wasn't for him, we would have lost our house."
The dashcam video shows Buddy meeting the trooper's vehicle, then dashing to their property about 55 miles north of Anchorage on April 4.
Heinrichs said he was working on parts for his truck when a spark hit some gasoline and ignited, lighting his clothes blaze. The 23-year-old man ran outside to stomp out the flames by rolling in the snow, closing the door to keep the blaze from spreading.
Heinrichs then realized Buddy was still inside the burning building and let the dog out. Heinrichs suffered minor burns on his face and second-degree burns on his left hand, which was still heavily bandaged Friday.
Buddy was not injured.
"I just took off running," Heinrichs said. "I said we need to get help, and he just took off."
Buddy ran into the nearby woods and onto Caswell Loop Road, where the dog encountered the trooper, Terrence Shanigan, whose global positioning device had failed while responding to a call about the fire. He was working with dispatchers to find the property in an area with about 75 miles of back roads.
Shanigan was about to make a wrong turn when he saw a shadow up the road. His vehicle lights caught Buddy at an intersection, and the dog eyed the trooper and began running down a side road.
"He wasn't running from me, but was leading me," he said. "I just felt like I was being led ... it's just one of those things that we're thinking on the same page for that brief moment."
The video shows Buddy occasionally looking back at the patrol car as he raced ahead, galloping around three turns before arriving in front of the blaze, which was very close to the Heinrichs' home.
From there, the trooper guided firefighters to the scene.
The workshop was destroyed and a shed was heavily damaged, but only some window trim on the house was scorched.
The Heinrich family said they knew Buddy was smart ever since they got him six weeks after he was born to a canine-officer mother and that he was brave, twice chasing bears away while Ben Heinrichs was fishing.
But saving their home beat them all.
"Downright amazing, I would say," said Tom Heinrichs, Ben's father. "Maybe there was some divine intervention.

The Dangerous Side Of Sugar


As if you needed another good reason to kick your soda habit, a new study from the Journal of the American Medical Association reveals that a diet heavy in added sugar is linked to elevated triglyceride levels and may increase your risk for a heart attack.
Added sugars such as cane sugar, beet sugar, high-fructose corn syrup, glucose, fructose, evaporated cane juice, fruit juice concentrate, and honey are used to sweeten packaged foods like sodas and fruit drinks, cereal, candy, cookies, and baked goods. In the study published this week, researchers at Emory University found that individuals who consume large amounts of added sugar have lower HDL ("good") cholesterol levels and higher triglyceride levels than individuals who eat less of the sweet stuff. Among women only, high added sugar intake was also linked to increased LDL ("bad") cholesterol levels. All of these red-flag numbers-low HDL, high triglycerides, high LDL-are independent risk factors for heart disease, which means that guzzling sugary coffee drinks and chomping down cookies may be putting your ticker in harm's way.
Research has already shown that regular consumption of foods high in added sugars is associated with weight gain, type 2 diabetes, and cavities, but this is the first study of its kind to link sugar intake to cholesterol levels in humans. And that's bad news for Americans, who now consume about 16% of their daily total calories as added sugar. Soda is the number one source of added sugar, contributing about a third of all added sugar in the American diet.
Unfortunately, guidelines for added sugar intake are all over the map and hardly user-friendly. Last year, the American Heart Association released new recommendations advising that women consume fewer than 100 calories from added sugar daily and men consume fewer than 150 calories. While I'm glad the organization called attention to our population's growing sugar problem, these guidelines are very difficult to put into practice, especially since "added sugars" aren't specifically listed on nutrition labels. (The Nutrition Facts Panel lists "Sugars" under "Total Carbohydrate", but this refers to total sugar in the product. Total sugar is a combination of added sugars and naturally-occurring sugars found primarily in fruit and dairy products. While added sugars don't provide anything but empty calories, the natural sugars in fruit and dairy products come packaged with healthful nutrients like fiber, vitamins, and minerals and don't need to be strictly limited.)
Plus, in order to see if you're staying below the American Heart Association calorie cutoffs, you need to know that every gram of added sugar contributes 4 calories, and then do a little arithmetic. Complete hassle!
If you don't feel like tabulating your exact added sugar intake each day, follow my 4 guidelines and you'll automatically cut back on the added sugar in your diet.
Eliminate soda and sugary drinks (including sports drinks, sweetened waters, juice drinks, and caloric cocktails). Choose plain water or naturally flavored seltzer instead.
Use sugar (and other sweeteners like honey, maple syrup, agave, and molasses) sparingly. Add no more than 1 to 2 teaspoons in coffee, tea, or oatmeal.
Choose packaged foods with minimal added sugar. For example, cereals should have no more than 8 grams of sugar per serving.
Be selective with sweet splurges. Either allow yourself a daily sweet treat around 150 calories, or indulge in a more decadent dessert no more than once or twice a week. My favorite sweet treats are foods that balance sugar with something healthy, such as a scoop of ice cream or pudding-both high in calcium; 1 oz dark chocolate-has tons of antioxidants; or a dollop of whipped cream with berries-loaded with fiber and vitamin C.

AP-CNBC Poll: Most in US against legalizing pot


LOS ANGELES – Most Americans still oppose legalizing marijuana but larger majorities believe pot has medical benefits and the government should allow its use for that purpose, according to an Associated Press-CNBC poll released Tuesday.
Respondents were skeptical that crime would spike if marijuana is decriminalized or that it would lead more people to harder drugs like heroin or cocaine. There also was a nearly even split on whether government spends too much or the right amount enforcing marijuana laws. Almost no one thinks too little is spent.
Marijuana use — medically and recreationally — is getting more attention in the political arena. California voters will decide in November whether to legalize the drug, and South Dakota will vote this fall on whether to allow medical uses. California and 13 other states already permit such use.
The balloting comes against the backdrop of the Obama administration saying it won't target marijuana dispensaries if they comply with state laws, a departure from the policy of the Bush administration, which sought to more stringently enforce the federal ban on marijuana use for any purpose.
In the poll, only 33 percent favor legalization while 55 percent oppose it. People under 30 were the only age group favoring legalization (54 percent) and opposition increased with age, topping out at 73 percent of those 65 and older. Opposition also was prevalent among women, Republicans and those in rural and suburban areas.
Some opponents worried legalization would lead to reefer madness.
"I think it would be chaos if it was legalized," said Shirley Williams, a 75-year-old retired English teacher from Quincy, Ill. "People would get in trouble and use marijuana as an excuse."
Those like Jeff Boggs, 25, of Visalia, Calif., who support legalization said the dangers associated with the drug have been overstated.
"People are scared about things they don't know about," said Boggs, who is married and works for an auto damage appraisal company.
Americans are more accepting of medical marijuana. Sixty percent support the idea and 74 percent believe the drug has a real medical benefit for some people. Two-thirds of Democrats favor medical marijuana as do a slim majority of Republicans, 53 percent.
Peoples' views on legalizing marijuana or on allowing its use for medicinal purposes were largely uniform across different regions of the country, despite the fact that legal medical marijuana use is concentrated in the West.
Bill Hankins, 77, of Mason, Mich., opposes legalizing marijuana but strongly favors using the drug medicinally. Michigan is among the states that allow medical pot.
"It has been shown through tests to alleviate pain in certain medical conditions," said Hankins, who said he experimented with pot when he was younger. If Hankins fell gravely ill and "my doctor said I should have it to control the pain, I would use it," he said.
California was the first state to approve medical marijuana, in 1996, and has been the hub of the so-called "Green Rush" to legalize marijuana. But a patchwork of local laws in the state has created confusion about the law and lax oversight led to an explosion of medical marijuana dispensaries in some places.
In Los Angeles, the number of dispensaries exploded from four to upward of 1,000 in the past five years. Police believe some were nothing but fronts for drug dealers to sell marijuana to people who have no medical need, and the city recently adopted an ordinance to reduce that number to 70 in coming months.
Among those surveyed, 45 percent said the cost of enforcing existing laws is too high and 48 percent said it's about right. Democrats, men and young people were most apt to say the cost is exorbitant.
With state and local governments desperate for cash, some legalization proponents are pushing marijuana as a potential revenue stream. But only 14 percent of those surveyed who oppose legalization would change their mind if states were to tax the drug.
John Lovell, a spokesman with the California Narcotics Officers' Association, said he wasn't surprised by the poll results because people already are aware of widespread abuse of legal prescription drugs and alcohol.
"Given that reality, we don't need to add another mind-altering substance that compromises people's five senses," Lovell said.
Allen St. Pierre, executive director of the National Organization for the Reform of Marijuana Laws, said that, since the organization was formed in 1970, there's been a slow but steady erosion of opposition to marijuana.
"Every single metric is pushing toward a zeitgeist in marijuana reform," he said.
Ann Broadus, 58, of Petros, Tenn., strongly opposes legalization and medicinal use, but even she sees the day when the laws will change.
"Probably somewhere down the road it will be legalized, but I hope not," she said. "I think if it becomes legal, these druggies would be worse off."
The AP-CNBC Poll was conducted April 7-12, 2010, by GfK Roper Public Affairs and Media. It involved interviews with 1,001 adults nationwide on landline and cellular telephones. It had a margin of sampling error of plus or minus 4.3 percentage points.

10 Deadly Sins of Negative Thinking


The way to overcome negative thoughts and destructive emotions is to develop opposing, positive emotions that are stronger and more powerful.” – Dalai Lama
Life could be so much better for many people, if they would just spot their negative thinking habits and replace them with positive ones.
Negative thinking, in all its many-splendored forms, has a way of creeping into conversations and our thinking without our noticing them. The key to success, is learning to spot these thoughts and squash them like little bugs. Then replace them with positive ones. You’ll notice a huge difference in everything you do.
Let’s take a look at 10 common ways that negative thinking emerges — get good at spotting these patterns, and practice replacing them with positive thinking patterns. It makes all the difference in the world for you.
10 Deadly Sins of Negative Thinking
1. I will be happy once I have _____ (or once I earn X).
Problem: If you think you can’t be happy until you reach a certain point, or until you reach a certain income, or have a certain type of house or car or computer setup, you’ll never be happy. That elusive goal is always just out of reach. Once we reach those goals, we are not satisfied — we want more.
Solution: Learn to be happy with what you have, where you are, and who you are, right at this moment. Happiness doesn’t have to be some state that we want to get to eventually — it can be found right now. Learn to count your blessings, and see the positive in your situation. This might sound simplistic, but it works.
2. I wish I were as ____ as (a celebrity, friend, co-worker).
Problem: We’ll never be as pretty, as talented, as rich, as sculpted, as cool, as everyone else. There will always be someone better, if you look hard enough. Therefore, if we compare ourselves to others like this, we will always pale, and will always fail, and will always feel bad about ourselves. This is no way to be happy.
Solution: Stop comparing yourself to others, and look instead at yourself — what are your strengths, your accomplishments, your successes, however small? What do you love about yourself? Learn to love who you are, right now, not who you want to become. There is good in each of us, love in each of us, and a wonderful human spirit in every one of us.
3. Seeing others becoming successful makes me jealous and resentful.
Problem: First, this assumes that only a small number of people can be successful. In truth, many, many people can be successful — in different ways.
Solution: Learn to admire the success of others, and learn from it, and be happy for them, by empathizing with them and understanding what it must be like to be them. And then turn away from them, and look at yourself — you can be successful too, in whatever you choose to do. And even more, you already are successful. Look not at those above you in the social ladder, but those below you — there are always millions of people worse off than you, people who couldn’t even read this article or afford a computer. In that light, you are a huge success.
4. I am a miserable failure — I can’t seem to do anything right.
Problem: Everyone is a failure, if you look at it in certain ways. Everyone has failed, many times, at different things. I have certainly failed so many times I cannot count them — and I continue to fail, daily. However, looking at your failures as failures only makes you feel bad about yourself. By thinking in this way, we will have a negative self-image and never move on from here.
Solution: See your successes and ignore your failures. Look back on your life, in the last month, or year, or 5 years. And try to remember your successes. If you have trouble with this, start documenting them — keep a success journal, either in a notebook or online. Document your success each day, or each week. When you look back at what you’ve accomplished, over a year, you will be amazed. It’s an incredibly positive feeling.
5. I’m going to beat so-and-so no matter what — I’m better than him. And there’s no way I’ll help him succeed — he might beat me.
Problem: Competitiveness assumes that there is a small amount of gold to be had, and I need to get it before he does. It makes us into greedy, back-stabbing, hurtful people. We try to claw our way over people to get to success, because of our competitive feelings. For example, if a blogger wants to have more subscribers than another blogger, he may never link to or mention that other blogger. However, who is to say that my subscribers can’t also be yours? People can read and subscribe to more than one blog.
Solution: Learn to see success as something that can be shared, and learn that if we help each other out, we can each have a better chance to be successful. Two people working towards a common goal are better than two people trying to beat each other up to get to that goal. There is more than enough success to go around. Learn to think in terms of abundance rather than scarcity.
6. Dammit! Why do these bad things always happen to me?
Problem: Bad things happen to everybody. If we dwell on them, they will frustrate us and bring us down.
Solution: See bad things as a part of the ebb and flow of life. Suffering is a part of the human condition — but it passes. All pain goes away, eventually. Meanwhile, don’t let it hold you back. Don’t dwell on bad things, but look forward towards something good in your future. And learn to take the bad things in stride, and learn from them. Bad things are actually opportunities to grow and learn and get stronger, in disguise.
7. You can’t do anything right! Why can’t you be like ____ ?
Problem: This can be said to your child or your subordinate or your sibling. The problem? Comparing two people, first of all, is always a fallacy. People are different, with different ways of doing things, different strengths and weaknesses, different human characteristics. If we were all the same, we’d be robots. Second, saying negative things like this to another person never helps the situation. It might make you feel better, and more powerful, but in truth, it hurts your relationship, it will actually make you feel negative, and it will certainly make the other person feel negative and more likely to continue negative behavior. Everyone loses.
Solution: Take the mistakes or bad behavior of others as an opportunity to teach. Show them how to do something. Second, praise them for their positive behavior, and encourage their success. Last, and most important, love them for who they are, and celebrate their differences.
8. Your work sucks. It’s super lame. You are a moron and I hope you never reproduce.
Problem: I’ve actually gotten this comment before. It feels wonderful. However, let’s look at it not from the perspective of the person receiving this kind of comment but from the perspective of the person giving it. How does saying something negative like this help you? I guess it might feel good to vent if you feel like your time has been wasted. But really, how much of your time has been wasted? A few minutes? And whose fault is that? The bloggers or yours? In truth, making negative comments just keeps you in a negative mindset. It’s also not a good way to make friends.
Solution: Learn to offer constructive solutions, first of all. Instead of telling someone their blog sucks, or that a post is lame, offer some specific suggestions for improvement. Help them get better. If you are going to take the time to make a comment, make it worth your time. Second, learn to interact with people in a more positive way — it makes others feel good and it makes you feel better about yourself. And you can make some great friends this way. That’s a good thing.
9. Insulting People Back
Problem: If someone insults you or angers you in some way, insulting them back and continuing your anger only transfers their problem to you. This person was probably having a bad day (or a bad year) and took it out on you for some reason. If you reciprocate, you are now having a bad day too. His problem has become yours. Not only that, but the cycle of insults can get worse and worse until it results in violence or other negative consequences — for both of you.
Solution: Let the insults or negative comments of others slide off you like Teflon. Don’t let their problem become yours. In fact, try to understand their problem more — why would someone say something like that? What problems are they going through? Having a little empathy for someone not only makes you understand that their comment is not about you, but it can make you feel and act in a positive manner towards them — and make you feel better about yourself in the process.
10. I don’t think I can do this — I don’t have enough discipline. Maybe some other time.
Problem: If you don’t think you can do something, you probably won’t. Especially for the big stuff. Discipline has nothing to do with it — motivation and focus has everything to do with it. And if you put stuff off for “some other time”, you’ll never get it done. Negative thinking like this inhibits us from accomplishing anything.
Solution: Turn your thinking around: you can do this! You don’t need discipline. Find ways to make yourself a success at your goal. If you fail, learn from your mistakes, and try again. Instead of putting a goal off for later, start now. And focus on one goal at a time, putting all of your energy into it, and getting as much help from others as you can. You can really move mountains if you start with positive thinking.
Karmic Mantra

NASA's New Asteroid Mission Could Save the Planet


President Barack Obama set a lofty next goal this week for Americans in space: Visiting an asteroid by 2025. But reaching a space rock in a mere 15 years is a daunting mission, and one that might also carry the ultimate safety of the planet on its shoulders.
"It is probably the hardest thing we can do because the asteroid is not coming on a schedule," NASA chief Charles Bolden told reporters late Thursday after Obama announced his space vision.
And when a specific asteroid is eventually selected, the window to launch a spaceship toward it will be much less forgiving than the windows for NASA space shuttles bound for the International Space Station, Bolden said.
"The space station gives us five minutes," he explained. "I'm not sure what an asteroid gives us, but then it doesn't come again for a lifetime."
And there's another compelling reason for touching an asteroid: Saving the planet.
In a panel discussion that followed President Obama's Thursday space vision speech, astrophysicist John Grunsfeld -- a former NASA astronaut who flew on five shuttle missions -- suggested sending humans to purposely move an asteroid, to nudge the space rock to change its trajectory. Such a feat, he said, would show that humanity could deflect a space rock if one threatened to crash into the planet.
"By going to a near-Earth object, an asteroid, and perhaps even modifying its trajectory slightly, we would demonstrate a hallmark in human history," said Grunsfeld, who flew on three shuttle missions to fix the Hubble Space Telescope. "The first time humans showed that we can make better decisions than the dinosaurs made 65 million years ago."
Take the moon, Grunsfeld said. Tycho crater, a huge impact crater on the moon visible from Earth, was created when an asteroid crashed into it 95 million years ago, he said.
"The dinosaurs saw that," Grunsfeld told reporters. "Thirty million years later they're snuffed out when the same thing happens to the Earth." [Asteroids Up Close.]
If humanity doesn't develop a capability to meet space rocks head-on, and win, than it is almost a certainty that an asteroid will eventually threaten life on Earth, he added.
TV's Bill Nye the Science Guy, vice president of the Planetary Society, said the president's asteroid plan carries risk, since it sends astronauts so far from home. But it is a risk worth taking.
"You're saving all of humankind," Nye said. "That's worthy, isn't it?"
What's out there
Scientists estimate there are about 100,000 asteroids and comets near Earth, but only about 20,000 are expected to pose any risk of impact. NASA has found about 7,000 of those objects, 1,000 of them flying in orbits that could potentially threaten the Earth in the future, NASA scientists have said.
Astronomer Donald Yeomans, head of NASA's Near-Earth Object program office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., said there are about a dozen near-Earth asteroids that could be within reach of manned spacecraft, but most of those are relatively small. To make a crewed mission worth it, the target space rock would likely have to be at least 300 feet (100 meters) wide.
For comparison, the space rock that exploded in a magnificent fireball over Wisconsin this week was just 3 feet (1 meter) wide, Yeomans said.
"If you could study a few of them up-close, you get a better idea on how best to deflect them," Yeomans told SPACE.com."
And more asteroids are being found all the time. NASA's WISE infrared space telescope is discovering dozens of asteroids every day that were previously unknown. New surveys and spacecraft will add to that space rock bounty over the next 15 years to offer more candidates for a crewed asteroid mission, Yeomans said.
New firsts in space
The bold new mission for NASA unveiled by President Obama Thursday was ultimately aimed at sending humans to Mars in the mid-2030s. The asteroid mission is just the first step.
"By 2025, we expect new spacecraft designed for long journeys to allow us to begin the first-ever crewed missions beyond the moon into deep space," Obama said. "We'll start by sending astronauts to an asteroid for the first time in history."
Astronauts have been to the moon and it's time to do something new, Obama said. He pledged to revive the Orion spacecraft, initially canceled along with the rest of NASA's Constellation program building new rockets and spacecraft. Now it will be used as a space station escape ship and, later, play a role in deep space missions, Obama said.
A mission to an asteroid would likely take months. Astronauts would rendezvous with a space rock, not land on it because of its weak gravity, but NASA would not send humans to an asteroid to just look at it, Grunsfeld said.
"If you go up to this, you're going to want to crawl around on it and find out what makes it tick," Grunsfeld said. Tethers or pitons would be required to keep asteroid explorers from floating away, he added.
Astronauts on an asteroid mission would be flying outside the Earth's protective magnetosphere, which shields the planet from harsh space and solar radiation. Even the Apollo astronauts who landed and walked on the moon didn't face such a risk.
"It's every bit as exciting in a different way, we're going to deep space. You turn around and take a picture of the Earth, and it's going to be a dot. You're not even going to see the atmosphere," Nye said. "Going to an asteroid, man, it's tough and risky and dangerous, how cool is that?"
Space radiation and long-term isolation would be among the biggest challenges for deep space missions, said MIT professor Edward Crawley, who participated in the panel discussion with Grunsfeld and served on the White House committee that reviewed NASA's human spaceflight program.
Crawley recommended a tiered approach to training missions, with a series of ever-longer expeditions preparing astronauts to the long treks to asteroids and, eventually, Mars.
Understanding asteroids
In general, asteroids are no strangers to the people of Earth. Astronomers have long-watched the space rocks from the ground while spacecraft have visited -- some even landed on -- asteroids in deep space.
Today, Japan's Hayabusa spacecraft is returning back from a huge asteroid called Itokawa, where it attempted to collect samples to send back to Earth. Hayabusa is due to return in June. Meanwhile, NASA's ion-powered Dawn spacecraft is headed out to the asteroid belt to rendezvous with Vesta and Ceres, the two biggest space rocks in the solar system.
But robots are only as good as their programming, and ultimately still rely on human operators.
"Robots have never discovered things," Grunsfeld said. "People have discovered things, using robots."
There are secrets locked away on asteroids that may hold the key to understanding the formation of the solar system. Asteroids are thought to be the leftover remnants of the solar system's buildings blocks. The organic molecules and compounds on them may offer clues on how life began on Earth, and if it's possible elsewhere in the universe, Nye and Grunsfeld said.
For Yeomans, who has studied asteroids for 40 years, hearing President Obama's commitment to send humans to visit them was uplifting, to say the least.
"It was pretty exciting to hear him say that," Yeomans told SPACE.com. "Of course, Congress still has to pass the budget, so all these things are up in the air a bit."

Study: Changing Internet Passwords A Waste Of Time


Expert: If Your Identity Is Stolen, The Information Will Be Used Immediately; Make Personal Code Unique.
Reporting : Dave Carlin /NEW YORK (CBS) ―
Resetting your Internet passwords frequently is a security measure designed to keep you safe in cyberspace. However, a new study by a Microsoft researcher has found that constant changing is a giant waste of time and money and makes us no safer from identity thieves. The study concluded someone hacking into your computer and stealing your password is similar to a crook getting your house key. The crook will likely use it right away and not wait until after you've changed the locks. "As soon as they've got it, they're using it and then they're gone," said Lance Ulanoff, editor of PC Magazine. Ulanoff advises people to get stronger passwords in the first place. He said do not use your mother's maiden name or the names of your kids or pets. "Just mash a sentence together and you'll find that you'll really remember it," Ulanoff said. He used the example: "I fly through the air 23 times." Ulanoff also recommended password managers, downloaded for free, which create passwords for you. "You never have to remember a password again except for one and that's the master password," he said, adding new iris and finger scan technology will eventually replace traditional passwords. CBS 2 HD asked documentary film producer Ashley Nicole about her Internet passwords. She has 10 of them and changes them regularly. She confessed because of this she has a hard time remembering them. Even if it is useless to constantly reset them, Nicole planned to keep doing it anyway. "If it makes me feel more comfortable changing my password that's what I'm gonna do," she said. She added that now she will also take the extra time to make sure all her new passwords are tough nuts to crack. The Microsoft researcher came up with a calculation that one minute of each user's time each day equals about $16 billion a year.

German tablet PC sets out to rival Apple's iPad


BERLIN – The German maker of a new tablet PC is setting out to rival Apple's iPad with the promise of even more technology such as a bigger screen, a webcam and USB ports.
It is not, however, an "iPad killer" as it has been dubbed by some blogs but an alternative to its bigger rival, Neofonie GmbH's founder and managing director Helmut Hoffer von Ankershoffen told reporters on Monday in Berlin.
Ankershoffen stressed the system's openness: Two USB ports allow users to connect all kinds of devices with the WePad, from external keyboards to data sticks.
People who want to put music on their WePad do not have to have any particular software, Ankershoffen said — a blow at Apple's devices that require particular Apple software like iTunes.
The WePad's basic version, which comes with Wi-Fi and 16-gigabyte storage, is set to cost euro449 ($600), the larger 32-gigabyte version with a fast 3G modem is euro569.
Ankershoffen claimed that given its technological superiority and greater openness, "that's a bargain compared with the iPad."
The iPad — which hit stores in the U.S. less than a month ago — is on sale there starting at $499 for the smallest version, coming with Wi-Fi and a 16 GB storage.
The WePad, with its 11.6-inch screen, is powered by an Intel chip and relies on a Linux software basis which is compatible with Google's Android and all Flash applications, Ankershoffen said.
When it hits stores starting late July, it will also boast a complete open source office package, he said.
Reporters could not test the device at the press conference.
Berlin-based Neofonie — a small company of some 180 employees — claims it already has some 20,000 people interested in signing up for a pre-order, even though orders won't be formally accepted before April 27.
Ankershoffen declined to give a sales estimate. "Not thousands, not tens of thousands but many more will be sold before the end of the year," he said.
The WePad is to be assembled by a manufacturer in Asia — which Ankershoffen refused to name — that can ramp up production capacity according to demand, he said
Neofonie casts the WePad as helping the media industry find a way to market paid content and hopes to appeal to publishers, some of whom are disgruntled with Apple's pricing policy and restrictions.
The device would allow publishers to sell their content on its platform without monopolizing the customer relationship, as Apple's iTunes or Amazon's Kindle do, the company said.
Gruner + Jahr, one of Europe's largest magazine publishers, already has a partnership with Neofonie, offering the company's flagship magazine, Stern, on the platform.
"It will be the first magazine, but others will certainly follow," Stern's deputy chief Tobias Seikel said at the press conference.
Germany's biggest publisher, Berlin-based Axel Springer AG, is in talks with Neofonie, but no cooperation is planned yet, spokesman Christian Garrels said.
"We want to offer our company's brands on several platforms with a high range," Garrels told The Associated Press.
The company's flagship daily, Bild, previously had trouble with its iPhone application because Apple censors sexually explicit content, such as the paper's daily nude photo.
Apple's iPad will go on sale in Germany at the end of April, according to the company's Web site. This would give the iPad roughly a three month lead on its German competitor.
Neofonie seems determined to face its big California rival: The company distributed tasty red apples boasting the WePad's logo at the press conference.
However, both companies have to prove that the touch screen device will not only amaze the tech-savvy early users, but will also appeal to mainstream consumers at a time when people have already a lot of Internet-connected gadgets — smart phones, laptops, e-book readers, set-top boxes and home broadband connections.

EMAIL TRACKING - Useful Infromation


1) Any time you see an E-Mail that says forward this on to '10' (or however many) of your friends, sign this petition, or you'll get bad luck, good luck, you'll see something funny on your screen after you send it, or whatever, it almost always has an E-Mail tracker program attached that tracks the cookies and E-Mails of those folks you forward to.
The host sender is getting a copy each time it gets forwarded and then is able to get lists of 'active' E-Mail addresses to use in SPAM E-Mails, or sell to other spammers. Even when you get emails that demand you send the email on if you're not ashamed of God/Jesus .....that's E-mail tracking and they're playing on our conscience.
These people don't care how they get your email addresses - just as long as they get them. Also, emails that talk about a missing child or a child with an incurable disease - "how would you feel if that was your child"....E- mail Tracking!!! Ignore them and don't participate!
2) Almost all E-Mails that ask you to add your name and forward on to others are similar to that mass letter years ago that asked people to send business cards to the little kid in Florida who wanted to break the Guinness Book of Records for the most cards.
All it was, and all any of this type of E-Mail is, is a way to get names and 'cookie' tracking information for telemarketers and spammers - - to validate active E-Mail accounts for their own profitable purposes. You can do your friends and family members a GREAT favor by sending this information to them; you will be providing a service to your friends, and will be rewarded by not getting thousands of spam E-Mails in the future!
If you have been sending out (FORWARDING) the above kinds of E-Mail, now you know why you get so much SPAM!
Do yourself a favor and STOP adding your name(s) to those types of listings regardless how inviting they might sound!...or make you feel guilty if you don't!...it' s all about getting email addresses - nothing more!
You may think you are supporting a GREAT cause, but you are NOT!
Instead, you will be getting tons of junk mail later and very possibly a virus attached! Plus, you are helping the spammers get rich! Let's not make it easy for them!
Also: E-Mail petitions are NOT acceptable to White House, Congress or any other organization - i.e. social security, etc.
To be acceptable, petitions must have a signed signature and full address of the person signing the petition, so this is a waste of time and you're just helping the Email trackers.
