Amazing facts about Insects
2. Over 900,000 known species of insects exist throughout the world.
3. Each year, insects eat about a third of the world's food crops.
4. In contrast, each year the average person will "eat" several insects while they are sleeping. During the average lifetime, a person consumes about seventy insects and ten spiders during their sleep. According to some sources, beetles have a taste that is similar to apples while wasps taste like pine nuts.
5. The Department of Health and Human Services has set standards regarding how many insect parts are food can contain, called the Food Defect Action Levels. Chocolate can have up to eight insect fragments per hundred grams, while peanut butter can have only sixty fragments. Meanwhile, wheat flour can have 150 fragments per hundred grams and paprika can have 300 fragments.
6. The smallest insect in the world, the Tanzanian parasitic wasp, is smaller than the eye on a housefly. The largest insect is the goliath beetle, which can grow up to four and half inches long.
7. Slavery is not strictly a human condition. Amazon ants will steal larvae of other ants to be their slaves. They depend upon these slaves for their survival because Amazon ants are incapable of doing anything other than fight.
8. An ant is capable of lifting fifty times its own weight and is capable pulling thirty times its own weight.
9. The most dangerous ant in the world is the black bulldog ant. It lives in Australia and has killed several human beings. When provoked, it stings and bites at the same time.
10. There are about a million ants per person. Ants are very social animals and will live in colonies that can contain almost 500,000 ants.
11. A flea can jump about two hundred times the length of their body, which is about thirteen inches. This is the equivalent to a six foot tall human jumping nine hundred feet.
12. A cockroach can live nine days without eating. This is also the same amount of time that the body of a cockroach can live after its head has been cut off before it eventually dies from starvation.
13. Mosquitoes have forty-seven teeth. They do not use these to bite, however. Instead, they have a proboscis, which is a tubular appendage.
14. Mosquitoes are more likely to bite children than adults, blonde-haired people rather than brown-haired people, and people wearing dark clothing. They are also attracted to people who just ate bananas or finished exercising. This is because foods high in potassium and exercising cause your body to release lactic acid, which is attractive to mosquitoes.
15. Citronella does not repel mosquitoes through its smell. Mosquitoes dislike citronella because it irritates its feet.
16. Mosquitoes are responsible causing the most human deaths worldwide than any other animal-almost two million annually. They do this by transmitting diseases such as the West Nile virus, malaria, and Dengue fever. Second to this is the tsetse fly, which kills about 66,000 people annually.
17. Dragonflies are capable of flying sixty miles per hour, making them one of the fastest insects. This is good since they are in a big hurry, as they only live about twenty-four hours.
18. Flies jump backwards during takeoff.
19. A housefly will regurgitate its food and eat it again.
20. Termites outweigh humans by almost ten to one.
21. Termites have been known to eat food twice as fast when heavy metal music is playing.
22. There are more beetles than any other animal. In fact, one out of every four animals is a beetle.
23. The rhinoceros beetle is the strongest animal and is capable of lifting 850 times its own weight.
24. A spider's web is not a home, but rather a trap for its food. They are as individual as snowflakes, with no two ever being the same. Some tropical spiders have built webs over eighteen feet across.
25. More people are afraid of spiders than death. Amazingly, few people are afraid of Champagne corks even though you are more likely to be killed by one than by a spider.
26. The most poisonous spider is the black widow. Its venom is more potent than a rattlesnake's.
27. During its lifetime, a worker bee will only produce about one-twelfth of a teaspoon of honey.
28. Honeybees are more dangerous than snakes. Bees kill more people each year than all the poisonous snakes combined.
29. Butterflies have taste sensors in their feet and taste their food by standing on it. Although all species of butterflies have six legs, some keep their front legs tucked up under their body most of the time.
30. The butterfly was originally called the "flutterby."
31. The praying mantis is capable of turning its head 360 degrees. It is the only insect that can do this. It is also the only animal on Earth with only one ear.
32. Crickets and katydids have ears on their legs.
33. Aphids are born pregnant and can give birth when they are only ten days old.
34. Only male crickets can chirp and will chirp faster in warm weather than cool. In fact, you can determine the temperature by counting the number of chirps in fifteen seconds and adding it to 37.
35. The average bed contains between two million to six million dust mites.

Swine Flu - Facts
H1N1 (referred to as "swine flu" early on) is a new influenza virus causing illness in people. This new virus was first detected in people in the United States in April 2009. Other countries, including Mexico and Canada, have also reported people sick with this new virus. This virus is spreading from person-to-person, probably in much the same way that regular seasonal influenza viruses spread.
This virus is contagious but, at this time, it not known how easily the virus spreads between people. The symptoms of H1N1 swine flu in people are similar to the symptoms of regular human flu and include fever, cough, sore throat, body aches, headache, chills and fatigue. Some people have reported diarrhoea and vomiting associated with H1N1 swine flu. Severe illness (pneumonia and respiratory failure) and even deaths have been reported with H1N1 swine flu infection. Like seasonal flu, H1N1 swine flu may cause a worsening of underlying chronic diseases.
In children, emergency warning signs that need urgent medical attention include:
* Fast breathing or difficulty in breathing
* Bluish or gray skin colour
* Not drinking enough fluids
* Severe or persistent vomiting
* Not waking up or not interacting
* Being so irritable that the child does not want to be held
* Flu-like symptoms improve but then return with fever and worse cough
In adults, emergency warning signs that need urgent medical attention include:
* Difficulty in breathing or shortness of breath
* Pain or pressure in the chest or abdomen
* Sudden dizziness
* Confusion, Severe or persistent vomiting
* Flu-like symptoms improve but then return with fever and worse cough
How do you catch H1N1 (swine) flu?
Spread of H1N1 (swine) flu can occur in two ways:
H1N1 virus appears to be transmitted the same way that seasonal flu spreads. Flu viruses are spread mainly from person to person through coughing or sneezing by people with influenza. Sometimes people may become infected by touching something with flu viruses on it and then touching their mouth or nose.
How can someone with the flu infect someone else?
Infected people can infect others right from day one even before they themselves develop any symptoms up to seven or more days after becoming sick. That means that one can pass on the infection to someone else before he/she even knows that he/she is sick, as well as while one is sick.
What can I do to protect myself from getting sick?
There is no vaccine available right now to protect against H1N1 (swine) flu. There are everyday actions that can help prevent the spread of germs that cause respiratory illnesses like influenza. Take these everyday steps to protect your health:
* Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
* Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective.
* Avoid touching your eyes, nose or mouth. Germs spread this way.
* Try to avoid close contact with sick people.
* If you get sick with influenza, you should stay at home and not go for work or school and limit contact with others to prevent them from getting infecting by you.
* Reduce the time spent in the crowded settings.
* Improve airflow in the living space by opening the windows and proper ventilation.
* Practice good health habits including adequate sleep, eating nutritious food, and keeping physically active.
How long can influenza virus remain viable on objects (such as books and doorknobs)?
Studies have shown that influenza virus can survive on environmental surfaces and can infect a person for up to 2-8 hours after being deposited on the surface.
Germs can be spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth. Droplets from a cough or sneeze of an infected person move through the air. Germs can be spread when a person touches respiratory droplets from another person on a surface like a desk, for example, and then touches his own eyes, mouth or nose before washing hands.
Are there medicines to treat H1N1 (swine) flu?
Yes, use of oseltamivir (brand name Tamiflu ?) or zanamivir (brand name Relenza ?) for the treatment and/or prevention of infection with these H1N1 (swine) influenza viruses. Antiviral drugs are prescription medicines (pills, liquid or an inhaler) that fight against the flu by keeping flu viruses from reproducing in your body. If you get sick, antiviral drugs can make your illness milder and make you feel better faster. They may also prevent serious flu complications. For treatment, antiviral drugs work best if started soon after getting sick (within two days of symptoms).
Follow the advice of your local public health department regarding school closures, avoiding crowds and other measures to reduce flu transmission. These measures will continue to be important after a novel H1N1 vaccine is available because they can prevent the spread of other viruses that cause respiratory infections.
What should I do if I get sick?
If you live in areas where people have been identified with new H1N1 flu and become ill with influenza-like symptoms, including fever, body aches, runny or stuffy nose, sore throat, nausea, or vomiting or diarrhoea, you should stay home and avoid contact with other people, except to seek medical care
. If you have severe illness or you are at high risk for flu complications, contact your health care provider or seek medical care. Your health care provider will determine whether flu testing or treatment is needed.
Antiviral drugs may reduce the symptoms and duration of illness, just as they do for seasonal influenza. They also may contribute to preventing severe disease and death. WHO is in touch with public health authorities and clinicians in affected countries and is gathering information about how effective the drugs are.
What about using a mask? What does WHO recommend?
If you are not sick you do not have to wear a mask. If you are caring for a sick person, you can wear a mask when you are in close contact with the ill person and dispose of it immediately after contact, and clean your hands thoroughly afterwards.
If you are sick and have to travel or be around others, cover your mouth and nose.
Using a mask correctly in all situations is essential. Incorrect use actually increases the chance of spreading infection.
How do I know if I have influenza A (H1N1)?
You will not be able to tell the difference between seasonal flu and influenza A (H1N1) without medical help. Typical symptoms to watch for are similar to seasonal viruses and include fever, cough, headache, body aches, sore throat and runny nose. Only your medical practitioner and local health authority can confirm a case of influenza A (H1N1). If they suspect any symptoms they will send your blood sample, throat swab and nasopharyngeal (nose to mouth) for testing to laboratories. Presently this facility is available only at certain specified government laboratories.

Eclipse Facts
- Lunar eclipses can only occur during a full moon.
- Solar eclipses can only occur during a new moon.
- A Solar eclipse always occurs two weeks before or after a lunar eclipse.
- Eclipses very often occur in threes, alternating lunar, solar and lunar.
- The maximum time a lunar eclipse can last is 3 hours and 40 minutes.
- The longest time the Moon can stay in totality is 1 hour 40 minutes.
- The maximum time for a total solar eclipse is 7 minutes and 40 seconds.
- The maximum time for an annular solar eclipse is 12 minutes 24 seconds.
- Lunar eclipses can occur up to 3 times a year.
- Solar eclipses can occur at least 2 and no more than 5 times a year.
- Lunar eclipses are visible over an entire hemisphere.
- Solar eclipses are visible in a narrow path a maximum of 167 miles wide (269km.)
- At any geographic position on the Earth, a total solar eclipse occur an average of once every 360 years.
- The cycle of eclipses repeats every 18.6 years called the saros.
- The eclipse shadow moves at 2,000 mph at the Earth's poles and 1,000 mph at the Earth's equator.
What is a Solar Eclipse?
A solar eclipse occurs when the moon passes between the Sun and the Earth so that the Sun is fully or partially covered. This can only happen during a new moon, when the Sun and Moon are in conjunction as seen from the Earth. At least two and up to five solar eclipses can occur each year on Earth, with between zero and two of them being total eclipses.
By a fortunate coincidence, the sun's diameter is 400 times larger than that of the moon, and at the same time, it is 400 times as far away. From where we are, this creates the illusion that they are the same size. If we look through a filter at the sun, it looks exactly like the moon on a full moon night. When the moon passes in front of the sun, the shadow falls on the earth and it appears to exactly cover the sun's disc. This is what a solar eclipse is - a shadow.
During a solar eclipse, the moon actually casts two shadows towards earth. One shadow shaped like a cone is called the umbra. This becomes narrower as it reaches the earth. No direct sunlight penetrates into this area. The path of this is called the path of totality. If you are positioned in this area than you can see a complete blocking of the sun and view a total solar eclipse. Total eclipse is observable only within a narrow strip of land or sea over which the umbra passes.
The second shadow is called the penumbra which spreads out as it reaches the earth. The penumbra is spread over a large area. People viewing the eclipse from this area of the earth's surface will see only a partial blocking of the sun.
