Difference between Turtle, Terrapin, and Tortoise

All three animals come under the class of reptiles, in the taxonomic order of Testudines or Chelonia. They all have the major characteristics of reptiles as they are cold-blooded, have scales, breathe air, and lay eggs on land.

The distinction between them comes mainly from what living habitat they are adapted for, though the terminology differs slightly in certain countries. In Australia, other than marine sea turtles, they are all called tortoises. In the United States, the term ‘turtles’ is given to chelonians that live in or near water.

In general there are a few commonly accepted distinctions between turtles, tortoises, and terrapins. Turtles may be completely aquatic, like sea turtles, which rarely come up onto land, except to lay eggs. Other types of turtles are semi-aquatic and live by fresh water ponds or lakes. They tend to swim, but also spend a lot of time on land, basking in the sun and occasionally burrowing in the mud. Turtles have adapted to an aquatic life and are streamlined for swimming with webbed feet, or in the case of sea turtles, long flippers. Turtle are omnivores. Depending on the type of turtle, they may eat jelly-fish, small invertebrates, sea sponges, and other sea-vegetation. In the case of fresh water turtles, they may eat plants, insects, and small fish.

Tortoises are almost exclusively land-dwelling, usually with stubby feet, and are not good swimmers. They occasionally enter water to clean themselves off or drink water, but can easily drown in the deep or in strong currents. Their bodies are adapted to living on land and have high domed shells and column shaped feet much like elephants. They also sometimes have sharp claws for digging . Tortoises are mostly herbivorous and primarily eat low-lying shrubs, cacti, grasses, weeds, fruit, and other vegetation.

The term terrapins is sometimes used for turtles that are semi-aquatic and live near brackish waters or swampy regions. They are sort of like a mix between a turtle and tortoise, as they spend most of their time divided between water and land. They are also usually small and have a hard-shell that is shaped somewhere between a turtle’s streamlined one and a tortoise’s rounded dome shaped one.

Eleven Benefits of Chocolate

As we approach the holidays, let me make it easier for you to indulge on a traditional holiday treat. A recently completed European study of chocolate eating among teens showed those who regularly consumed chocolate have less total and abdominal body fat than those who do not. The findings are based on data from 1,458 youths ages 12 to 17, who were part of the Healthy Lifestyle in Europe by Nutrition in Adolescence study, which examines lifestyle habits among youths in nine countries in Europe. The study did not differentiate between dark or light chocolate.

Although most studies claim dark chocolate is better for you, there is no need to rule out light chocolate.
Benefits of eating chocolate show:
A 20% reduced risk of stroke,
Lower blood pressure,
Lower risk of heart attack,
Helps keep you feeling fuller longer,
Increases insulin sensitivity (reducing risk of diabetes),
Dark chocolate flavonoids are good for your skin,
Theobromine in chocolate reduces activity of the vagus nerve to ease coughing,
Increases a positive mood and reduces stress,
Cocoa has blood thinning properties,
Improves vision.

White chocolate is really not chocolate, because it does not contain cocoa solids. It is a chocolate derivative and usually consists of cocoa butter, sugar, milk solids, and salt.

Baked Eggs

Baked eggs are better because they are less sulfurous smelling and the texture of the finished eggs is creamier. Try baking them at 325 degrees for 30 minutes. You might enjoy the difference.

Even More Inventions from Women

Patsy Sherman's role in the invention of Scotchgard™ was a "happy mistake". As a research chemist with 3M in 1953, a lab mishap with fluorochemicals lead her to a new discovery. An assistant accidentally dropped a bottle of synthetic latex that Sherman had made, it splashed onto the assistant's white canvas tennis shoes. The substance did not change the look of the shoes it couldn't be washed away by any solvents, and it repelled water, oil and other liquids.

In 1813, Tabitha Babbitt created the circular saw. It was circular so that the teeth would continue cutting, unlike the straight saws that only cut on the pull and not the push motion. Her other building innovations, like machine-cut nails instead of individually hand-crafted nails. As a Massachusetts Shaker community member, she helped create tool innovations for furniture making. She lived a simple Shaker life and never applied for patents.

The inventor of "Liquid Paper" or "White-Out" was Betty Nesmith Graham. Graham got an idea she had seen done by sign painters, which was to add another layer of paint to cover-up mistakes. She used a kitchen blender to mix-up her first batch of substance to cover-up over mistakes made on paper at work. After much experimenting and then being fired for spending so much time distributing her product as a trial, she received a patent in 1958.

200 Types of Cancer

The reason is that there are over 200 different types of cells in the human body with each of these having the potential to become cancerous. Cancer can develop in any of the over 60 organs in the body. Cancers are named for the part of the body where it started and the type of cell that has become cancerous. All cancers start because abnormal cells grow out of control. There are two general categories of cancer. Carcinomas are cancers that develop on the surface linings of the organs. Sarcomas are cancers that develop in the cells, and they affect solid tissues, such as muscle and bone. They can also develop in the blood vessels. Cancer tumors can either be malignant or benign.

Normal healthy cells divide and die as they should. The average number of times normal healthy cells divide is known as the Hayflick Limit. It was named after Dr. Leonard Hayflick, who in 1965 noticed that cells divide a specific number of times before the division stops. The average was between 40-60. (There is one woman who had tissue in her body that could divide apparently forever: The Woman with Immortal Cells)

If you took every cell in your body, at the time you were born, and accounted for all the cells they would produce and multiplied that number by the average time it takes for those cells to die, you get what is known as the ultimate Hayflick limit or the maximum number of years you can theoretically live. This is how researchers come up with the theoretical life limit of 120 years.

For the first time since the government began collecting mortality data early in the last century, cancer death rates began to decline in 1993. It significantly declined from 1994 to 1998 with a non-significant decline from 1998 to 2001 and falling death rates from 2001 to 2008. In 2008, the death rate for all cancers was 175.67 per 100,000 people in the US. Cancer is not contagious.

Happy Friday

In the endless war between trees and matches, trees always win because they have learned to grow.

We also grow as we strive to enjoy a Happy Friday!

Laser Headlights are Coming

BMW is working on laser (Light Amplification by Stimulated Emission of Radiation) headlights to be introduced on selected 2014 models. They promise to be much better than the relatively recent LED headlights. The laser lights will put out more light and use two-thirds the power of LEDs, which use one fourth the power of ordinary headlights. They are also much more efficient and brighter than the current Xenon headlights used on some cars. In addition, they are just 10 square micrometers and 1/10,000th the size of a 1-square-millimeter LED.

The inventor of the headlights says Laser lighting may even do away with household LED and CFL lighting before either takes off. These new Laser lights are also ideal for businesses, signage, and projectors used in movie theaters, as well as smartphone projectors. The Laser lights are different than you might think of a laser beam. These lights are diffused blue beams and reconstituted to a white specific width for use. There is no danger of an accident creating a beam that could be harmful to the naked eye.

Einstein came up with the theoretical foundation for lasers in 1917 and they were first demonstrated in 1947. They have been in use since then for various applications, but almost always as a concentrated beam.

It took from 1879, when the incandescent light began until a few years ago for radical change, now we have another whole new generation of lighting in about five years. In spite of the hype from manufacturers, it will likely be a few more years before we can buy one for our homes.

World Toilet Day

The United Nations General Assembly adopted a resolution to mark "World Toilet Day." The day will be celebrated November 19. "The amusement and laughter likely to follow the designation of 19 November as 'World Toilet Day' would all be worthwhile if people’s attention was drawn to the fact that 2.5 billion people lacked proper sanitation and 1.1 billion were forced to defecate in the open, the General Assembly heard today," a U.N. press release reads.

“Ending open defecation will lead to a 35 per cent reduction in diarrhea, which results in over 750,000 deaths of children under five years of age every year,” Singapore’s representative said. Apart from establishing World Toilet Day, the text also urged Member States and the United Nations system to encourage behavioral change, to introduce policies that would increase sanitation among the poor.

India's novel approach is to encourage families not to let their daughters  marry if the potential husband does not have a toilet. The initiative from the government is called "No toilet, no bride". There are more temples than toilets in India, said Union Minister Jairam Ramesh.

The Indian state of Madhya Pradesh pays for a wedding and provides qualifying couples with housewarming gifts totaling 15,000 rupees (about $270) if they can prove the husband-to-be's house has a toilet.

Over 75 per cent of the 1.2 billion Indian population currently have a mobile phone subscription, but only 50 per cent of households have a toilet and only 11 per cent have one connected to the sewerage system, according to the 2011 Indian census. I love the headline from the Washington Post, "In India, New Seat of Power for Women".

Four More Inventions by Women

Stephanie Kwolek invented Kevlar, a tough durable material now used to make bulletproof vests. For years she'd worked on the process at DuPont and in 1963, she got the polymers or rod-like molecules in fibers to line up in one direction. This made the material stronger than others, where molecules were arranged in bundles. In fact, the new material was as strong as steel! Kwolek's technology also went on to be used for making suspension bridge cables, helmets, brake pads, skis, and camping gear.

Patricia Bath, MD - Patented in 1988, a new method of removing cataracts. The medical laser instrument made the procedure more accurate and is termed the cataract Laserphacoprobe. As a laser scientist and inventor, she has 5 patents on the laser cataract surgery device covering the United States, Canada, Japan, and Europe.

What is the Blissymbol Printer? It's a software program invented by a Canadian 12-year-old in the mid-1980s. Rachel Zimmerman's printer enables those with severe physical disabilities like cerebral palsy, to communicate. The user records their thoughts by touching symbols on a page or board through the use of a special touch pad, the printer then translates the symbols into a written language. Zimmerman's system started as a project for a school science fair, but ended up competing and winning a silver medal in a nationwide contest, as well as gaining her the YTV Television Youth Achievement Award.

Before the paper bag, the first version was shaped like an envelope, with no flat bottom.  Margaret Knight created a machine to cut, fold, and glue square bottoms to paper bags and gained a patent for it in 1871, but not without a lawsuit against a fellow who stole her idea. His defense was "a woman could never design such an innovative machine," but she had the drawings to prove the invention was hers and she won the case. Knight's career with inventions started at age 12, when she developed a stop-motion device that immediately brought industrial machines to a halt if something was caught in them. Over the course of her lifetime, she was awarded over 26 patents.

What's in a Name, White Elephant

Sacred white elephants were and are kept by some Southeast Asian monarchs. Possessing a white elephant was regarded, and still is in Thailand and Burma (Myanmar) as a sign that the monarch reigned with justice and power, and that the kingdom was blessed with peace and prosperity.

It derives from stories that the kings of Siam would make a present of one of these animals to courtiers who were obnoxious or unpleasing, in order to ruin the recipient by the cost of its maintenance. A white elephant was a valuable, but burdensome possession, which its owner could not dispose of and whose cost and upkeep was out of proportion to its usefulness or worth.

These days a white elephant can mean an object, business venture, etc., that is without practical use or value. The term is used in business and even more frequently used during the gift-giving holiday season as friends and relatives strive to find unique gifts to give. Many people consider dried fruit cakes as white elephants.
