Green Tea Break

Green tea is a type of tea, where the tea leaves have been dried by steaming and baking. Green tea, also known as Chinese tea, originated in China, approximately 5000 years ago, and has gained popularity in the rest of the world, more in the United States of America, as a health beverage. Green tea is made from the leaves of the Camellia Sinesis plant, whose leaves undergo minimal oxidation, instead of being fermented in order to retain its flavor and color. Though there are many varieties of green tea that are available in the market, the most popular and best green tea is the Japanese green tea called Myou-Kou. It is one of the best green tea varieties because of its bolder and thicker flavor, as compared to other lighter green teas. Its leaves are steamed, giving out a grassy aroma, making it the best green tea. Let’s see more about the best green tea and its benefits. Don’t forget to read green tea facts.

Every day Green energy is becoming increasingly more popular day by day as it provides thousands of benefits. It is a wide ranging, sustainable, and reliable energy source that requires little or no maintenance and is beneficial in the long term. The use of green energy is a particularly trustworthy way to save on monthly electric bills. It utilizes sunlight to produce electricity and is renewable. Solar energy is a form of green energy. Moreover solar energy is beneficial for our health as it does not release harmful pollutants into the air nor does it pollute the environment.

The following will show some of the most effective benefits of this renewable energy. This way you will be able to easily understand the importance green energy.

1. Green or solar energy is energy in a sustainable form. Solar photovoltaic cells use sunlight to generate electricity and constantly provide a sustainable energy source for long-term daily usage.

2. Solar energy panels require little maintenance and are energy efficient. After a solar panel is installed, it generally does not require fuel or lubricant to continue working. Solar electric system have no recurring cost and offers maximum.

3. Solar energy does not contribute to global warming as it is a natural form of energy. Because they don’t run on fuels, solar panels do not put out any greenhouse gases, carcinogens, carbon dioxide or other poisonous gases in the environment.

4. One of the most important advantages to green energy is that it does not cause any negative effects to human health. Since, it is environmentally-friendly and promotes a clean environment for every one of us, the risks of respiratory diseases, cardiac dangers and eyesight impairment are also reduced.

5. Solar photovoltaic cells are quite. They produce energy silently without making any noise. This is another big advantage of green energy

6. Solar panel installation can be expensive unless you install the panels yourself. And with new technology, the self installation of solar panels is becoming more and more popular. Plus once they are installed, they will generate an infinite amount of energy. As a result you will definitely save you money over the long run.

7. Reliability is a major benefit of green energy. You will not have to worry about replacing parts of a solar electric system.

8. Solar panels are self-efficient and produce limitless amounts of energy.

Search engine giant Google realizes how important clean/green energy is to the future of this country and the future of the world. The technology is here and there is no reason not to invest in it! Google has put its money where its mouth is and invested 168 million dollars in a mojave dessert energy plant. Google has picked BrightSource Energy to develop and operate the enormous solar power plant. The project is called “Ivanpah.” It is a solar electric generating system that uses solar thermal technology and “an environmentally responsible design,” to deliver reliable, clean and low-cost power. The plant will have a verity of large mirrors reflecting the suns light to a receivers attached to large towers called a power towers. Because the concentration point of the reflected sunlight will be a fairly small area, the power towers become very efficient at producing energy. For more information, please see the video below.

We’ve never been a big fan of Fox here at Green Tea Break, but this joke was not only hilarious, but also in good taste.

The physics blogs are abuzz with rumours that a particle of dark matter has finally been found.

If it is true, it is huge news. Dark matter is thought to make up 90 per cent of the universe’s mass and what evidence there is for it remains highly controversial. That’s why any news of a sighting is seized upon.
The Cryogenic Dark Matter Search experiment is one of several designed to look for the tell-tale signature of dark matter particles passing through. No one is sure what a dark matter particle will look like, though theory gives some pointers.
Most of the experiments have been designed to look for elusive massive particles called WIMPS that barely register as they pass through matter, because the only forces they experience are gravity and the weak nuclear force.
CDMS is located deep underground in the Soudan mine in Minnesota, to protect it from the hail of cosmic rays that would otherwise wash out any dark matter signal.
Earlier this year, the collaboration published a paper in Physical Review Letters (vol 102, p011301) based on two series of experiments between October 2006 and July 2007. They found nothing.
So researchers have been waiting eagerly for the next chapter of the story – maybe with more time, more experience running their detector and a sprinkling of luck, the team would spot a dark matter particle.
The gossip mill went into overdrive after a rumour leaked out that the CDMS collaboration has had a paper accepted by the journal Nature. Word is that the paper will appear in the 18 December issue.

Nature is an unusual place for particle physicists to publish their papers and this has prompted speculation that the news must be big.
A few physicists I know say that talks have hurriedly been scheduled for 18 December at SLAC National Laboratory, the University of California Santa Barbara and Fermilab – all prominent institutions within the CDMS collaboration.
We’ll have to wait and see if the rumours turn out to be true. Even if not, with NASA’s Fermi satellite looking for dark matter in space and the Large Hadron Collider up and running, 2010 could be the year we finally crack the dark matter mystery.

Think black holes are strange? Understandable, considering these powerhouses of the universe (many times heavier than our sun) are collapsed stars with gravity so strong that even light cannot escape their grasp.

But maybe they’re not “strange” enough, some astrophysicists suggest. “Stellar” black holes, ones only a few times heavier than the sun, may actually be something even weirder called a quark star, or “strange” star.

A physics team led by Zoltan Kovacs of the University of Hong Kong sizes up the issue in the current Monthly Notices of the Royal Astronomical Society. Quark stars are only theoretical right now, but “the observational identification of quarks stars would represent a major scientific achievement,” Kovacs says.

If quark stars exist, it could prove a theory that normal matter – the stuff of people, planets and stars – isn’t stable and could help explain the existence of the “dark matter” that fills much of the universe.

First suggested in 1970, a strange star is a collapsed star that doesn’t quite crumple enough to turn into a full-fledged black hole and yet is too heavy to become a so-called neutron star (at least 1.4 times heavier than the sun.) Neutron stars do exist, as astronomer Jocelyn Bell showed with the discovery of a pulsar, a spinning neutron star that streams particles from its poles.

In a quark star, gravity would be so strong that it squeezes the subatomic particles called quarks right out of the protons and neutron building blocks of the original star’s atoms. That would leave behind a solid mass of quark stuff called strange matter, hence the name “strange star.”

Earlier in the decade, astronomers suggested that a neutron star called RX J1856, about 400 light-years away (one light-year is about 5.9 trillion miles) was about one-third too small and might be a quark star. But a 2004 Nuclear Physics B journal report showed the star’s intense magnetic field explained its size, so it really was a neutron star.

So, if size alone won’t reveal a quark star, what will? In the new study, Kovacs and his colleagues, Cheng Kwong-sang and Tiberiu Harko, analyze the disks of dust and gas circling supposed black holes. Whipped to high speeds by the intense gravity of a black hole, these disks are thought to heat to high temperatures and emit powerful radiation. For a quark star, the radiation would be about 10% less than predicted around a black hole, they find. And a quark star would give off a dim light (called bremsstrahlung emission), unlike a black hole, emitted by a thin layer of electrons on its surface.

As the swine flu outbreak strikes the U.S. early and hard, health officials note a worrisome number of child deaths and warn that supplies of vaccine will remain scarce for at least the next couple of weeks.

Delays in producing the vaccine mean 28 million to 30 million doses, at most, will be divided around the country by the end of the month, not the 40 million-plus states had been expecting. The new count from the Centers for Disease Control and Prevention means anxiously awaited flu-shot clinics in some parts of the U.S. may have to be postponed.

It also delays efforts to blunt increasing infections. Overall, what CDC calls the 2009 H1N1 flu is causing widespread disease in 41 states, and about 6 percent of all doctor visits are for flu-like illness — levels not normally seen until much later in the fall.

Federal health officials said Friday 11 more children have died in the past week because of the virus.The Centers for Disease Control and Prevention says about half of the child deaths since September have been among teenagers. And overall for the country, deaths from pneumonia and flu-like illnesses have passed what CDC considers an epidemic level.

“These are very sobering statistics,” says the CDC’s Dr. Anne Schuchat.
This new strain is different from regular winter flu because it strikes the young far more than the old, and child deaths are drawing particular attention. Eighty-six children have died of swine flu in the U.S. since it burst on the scene last spring — 43 of those deaths reported in September and early October alone, said Schuchat.

During the week of September 27-October 3, 2009, influenza activity continued to increase in the United States. Flu activity is now widespread in 37 states. Nationwide, visits to doctors for influenza-like-illness increased over last week and are higher than expected for this time of year. In addition, flu-related hospitalizations and deaths are increasing as well, and are higher than expected.
