Cancer Detection Through Nails

Detecting the disease through toenails can be an alternative to determine whether there is cancer seeds are nesting in your body.

Recognizing the potential of cancer simply by observing the texture of your toenails is the latest breakthrough in anticipation of the disease before it develops into more severe, quoted from the pages of The Sun.

The research team University of San Diego, California, believe it after doing research on a group of smokers and non-smokers or passive. They measured levels of nicotine through the nail samples.

As a result, cigarette addicts were three times more likely to develop lung cancer than people who smoke only occasionally in his life or even a passive smoker.

The study reveals a person who has the seed of cancer, then the nails will not grow normally, which grows about one centimeter per year. This growth is much slower than normal nail growth. This gives guidance to those affected by long-term exposure to cigarette smoke at greater risk of getting cancer.

So, beware if you find any anomalies and abnormalities in your nails. Consult with your doctor, could be best way when you feel something is wrong with the texture of your nails.

Easy 9 Health Tips to Improve Health

1. Move More

Make it a daily challenge to find ways to move your body. Climb stairs if given a choice between that and escalators or elevators. Walk your dog; chase your kids; toss balls with friends, move the lawn. Anything that moves your limbs is not only a fitness tool, it’s a stress buster. Think ‘move’ in small increments of time. It doesn’t have to be an hour in the gym or a 45-minute aerobic dance class or tai chi or kickboxing. But that’s great when you’re up to it. Meanwhile, move more.

2. Cut Fat

Avoid the obvious such as fried foods, burgers and other fatty meats (i.e. pork, bacon, ham, salami, ribs and sausage). Dairy products such as cheese, cottage cheese, milk and cream should be eaten in low fat versions. Nuts and sandwich meats, mayonnaise, margarine, butter and sauces should be eaten in limited amounts. Most are available in lower fat versions such as substitute butter, fat free cheeses and mayonnaise.

3. Quit Smoking
The jury is definitely in on this verdict. Ever since 1960 when the Surgeon General announced that smoking was harmful to your health, people have been reducing their use of tobacco products that kill. Just recently, we’ve seen a surge in smoking in adolescents and teens. Could it be the Movies influence? It seems the stars in every movie of late smoke cigarettes. Beware. Warn your children of the false romance or ‘tough guy’ stance of Movie smokers.

4. Reduce Stress

Easier said than done, stress busters come in many forms. Some techniques recommended by experts are to think positive thoughts. Spend 30 minutes a day doing something you like. (i.e.,Soak in a hot tub; walk on the beach or in a park; read a good book; visit a friend; play with your dog; listen to soothing music; watch a funny movie. Get a massage, a facial or a haircut. Meditate. Count to ten before losing your temper or getting aggravated. Avoid difficult people when possible.

5. Protect Yourself from Pollution
If you can’t live in a smog-free environment, at least avoid smoke-filled rooms, high traffic areas, breathing in highway fumes and exercising near busy thoroughfares. Exercise outside when the smog rating is low. Exercise indoors in air conditioning when air quality is good. Plant lots of shrubbery in your yard. It’s a good pollution and dirt from the street deterrent.

6. Wear Your Seat Belt
Statistics show that seat belts add to longevity and help alleviate potential injuries in car crashes.

7. Floss Your Teeth
Recent studies make a direct connection between longevity and teeth flossing. Nobody knows exactly why. Perhaps it’s because people who floss tend to be more health conscious than people who don’t?

8. Avoid Excessive Drinking
While recent studies show a glass of wine or one drink a day (two for men) can help protect against heart disease, more than that can cause other health problems such as liver and kidney disease and cancer.

9. Keep a Positive Mental Outlook
There’s a definitive connection between living well and healthfully and having a cheerful outlook on life.

Hybrid cars

Hybrid car is like its name suggests a car that uses more than one power sources to move the vehicle (usually two-combination of an internal combustion engine and one or more electric motors).

Hybrid cars have very expensive parts but they also have long lasting warranties that usually provide replacement of the most expensive parts if they get broken before the warranty is over.

Hybrid cars are recommended from environmental point of view because they emit significantly less emissions compared to conventional gasoline cars.

Hybrid cars have significantly higher fuel efficiency compared to conventional cars.

Currently the three most popular hybrid vehicles are Honda Civic, Honda Insight and Toyota Prius.

Toyota Prius belongs to power split hybrid category meaning that there are always two electric motors and one internal combustion engine. When on open road car uses internal combustion engine though when engine requires bigger power the electric motors are used to maximize the available power for a short time, giving the effect of having a larger engine than that actually installed, for instance when overtaking.

Honda Civic on the other hand belongs to mild parallel hybrid train configurations meaning that it uses a very compact electric motor to give extra output during the acceleration when bigger power is required.

Hybrid cars have very long history in Japan where they have been sold since 1997.

Hybrid cars still have relatively high production costs, mostly because of expensive materials used in their production, this is the reason why they cost in average $3500 more than their non-hybrid versions.

Hybrid cars are not totally environmentally acceptable because of the car batteries they use (nickel metal hydride), though it has to be said that general negative environmental effects of hybrid cars are very low.

Hybrid cars usually accelerate at slower speed compared to conventional cars.

Hybrid cars have significant battery storage capacity to store and reuse recaptured energy, which is especially handy in stop-and-go traffic (rush hours).

Hybrid cars usually recapture significant amounts of energy during braking that are in conventional cars wasted as heat.

Hybrid cars usually have better aerodynamics compared to traditional cars.

Toyota Prius is the best selling hybrid car, in fact Toyota Prius was the 11th bestselling vehicle in United States in 2008.

U.S. hybrid market is constantly growing as hybrid cars are becoming more and more popular, not only because they ensure better mileage but also because they have positive effect on climate change by emitting less emissions.

In New York alone there are currently more than 20,000 hybrid cars on the road though U.S. state that traditionally sells the most hybrid cars is California.

In average hybrid cars produce 80% less harmful pollutants and greenhouse gas emissions compared to conventional gasoline cars.

Hybrid cars generally produce between 60-90 horsepower. This may seem to some like a very big problem in strength but hybrid cars are constructed with ultra lightweight materials like carbon fiber or aluminum, meaning they are more aerodynamic which compensates for this loss in horsepower, and ensures high efficiency.

Many U.S. states are offering both cash and privilege incentives for consumers who purchase hybrid cars, mostly in order to decrease the total level of CO2 emissions that harm environment.

Interesting science facts about intelligence

It is very difficult to define intelligence since intelligence encompasses different capacities of our mind, such as to plan, to give reason, to solve different problems, etc.

Intelligence includes not only wisdom and quick thinking, but also creativity, personality, character, and of course our total knowledge.

The word intelligence comes from the Latin verb "intellegere", which means "to understand".

Some say that intelligence can be measured while majority agrees that IQ tests can tell us the level of our intelligence.

IQ tests that have lately become so popular to measure our intelligence were originally used to identify mentally "defective" children that needed special school programs.

There are lot of controversies about traditional IQ tests, and many agree that they cannot be the guide to how person is going to cope with everyday's life.

Some studies suggested how IQ is the product of interaction between multiple genes.

Genetic factor is very important and has a significant impact on IQ results.

Some genetic experiment on animals have showed that genetic engineering could be used to enhance the intelligence of animals, for instance genetically engineering mices have demonstrated superior ability in learning and memory skills in various behavioral tasks compared to "normal mices".

Intelligence involves processing new information and then making associations with other information that individual encounters throughout life.

Intelligence is strongly influenced by the quality of the brain's axons, or wiring that sends signals throughout the brain. The faster the signaling, the faster the brain processes information, resulting in better intelligence.

Artificial intelligence is term mostly used to describe intelligence of computers and other machines.

Human beings solve most of their problems using quick, intuitive judgments rather than the conscious, step-by-step deduction that would five more comprehensive results.

Artificial intelligence is becoming better and better but is still not good enough to totally replicate human intelligence.

Interesting science facts - Space & astronomy

 

Term "spacetime" was first used by Albert Einstein in his paper on a "Special theory of relativity", in which he proposed that space and time should be combined into a single construct known as "spacetime".

Word astronomy comes from two Greek words "astron" meaning star and "nomos" meaning law, and would basically mean law of the stars.

The defining feature of every black hole is the so called "event horizon". Event horizon is a surface in spacetime that marks a point of no return, and once an object crosses this surface, it cannot return to the other side.

In theory, there is no smallest size for a black hole.Almost 90% of all the incoming cosmic ray particles are protons.

Dark matter is matter that is undetectable by its emitted radiation, and its presence can be inferred from gravitational effects on visible matter. The dark matter component has much more mass than the "visible" component of the universe.

Each galaxy consists of stars and stellar remnants, an interstellar medium of gas and dust, and dark matter. Dark matter account for around 90% of the mass of most galaxies.

There are probably more than 100 billion galaxies in the observable universe. Galaxies come in three main types: ellipticals, spirals, and irregulars.

Nebula is an interstellar cloud of dust, hydrogen gas and plasma. Some nebulae are formed as the result of supernova explosions.

Extrasolar planets, or sometimes called exoplanets are planets beyond our solar system, orbiting a star other than our Sun.

Big bang theory is the most common theory of Universe origin. According to this theory universe has expanded some 12-14 billions years ago from a primordial hot and dense initial condition at some finite time in the past, and continues to expand to this day.

Asteroids are space bodies primarily found in the inner Solar System — that are smaller than planets but larger than meteoroids, with the exclusion of comets.

Comets are small Solar System Bodies that orbit the Sun and once close enough to the Sun, exhibit a visible coma (atmosphere) or a tail — as a result of solar radiation upon the comet's nucleus.

Some facts about tsunamis

Here are some quick and interesting facts about tsunamis and their devastating power.

The origin of tsunami doesn't necessarily have to be an earthquake. Tsunami can also be a result of volcanic eruption, landslides, meteor hit, etc.

Tsunamis are most frequent in Japan, up to now there have been close to 200 recorded tsunamis in Japan.

The recent earthquake with the magnitude of 8,9 that caused the tsunami in Japan wasn't the strongest tsunami-causing earthquake. In 2004, a 9.3 magnitude earthquake in northern Sumatra, Indonesia caused a extremely powerful tsunami with waves as high as 10.5 m moving at a speed of up to 8 m per second.

In some cases the large earthquake is not needed to create large tsunami. The scientists have calculated that even a moderate earthquake on a strike-slip fault can lead to huge tsunami.

The most simple definition of a tsunami would be a serious of powerful water waves caused by the displacement of a large volume of water.

Cities that lie near an area where two tectonic plates slide past each other (the so called strike-slip fault) have very high risk to be faced with destructive tsunamis. Los Angeles and Kingston are among these cities with very high tsunami risk.

The oldest recorder tsunami was the one that in the 365 A.D. devastated the ancient city of Alexandria.

The scientists have developed several different tsunami warning systems. The most important thing about tsunami warning system is that it needs to be flawlessly effective by allowing the perfect coordination of action for emergency officials. Today's computer models can predict tsunami arrival within minutes of the arrival time.

The destructive nature of tsunamis calls for building more resistant structures in areas with high tsunami risk in years to come.

The deep ocean tsunami has a wavelength of around 120 miles. More than three quarters of tsunamis (around 80%) occur in the Pacific Ocean.

It is still not possible (with the current technologies) to prevent tsunami from occurring. The best thing we can do is to try to reduce the damage by as much as possible (by for instance slowing tsunami, if possible of course).
