The Story of Prometheus

The Story of Prometheus


Destruction Leads to Preservation

In 1964, a scientist was granted permission by the United States Forest Service to study some of the bristlecone pines growing in a grove beneath Wheeler Peak. The researcher was studying the tree rings of these ancient trees, which were known to be over 4,000 years old. Bristlecone pines, like most trees, add a ring for each year of growth. Scientists can study the variation in width to determine patterns of good and bad growing seasons in past years. The trees literally record the seasons of their lives in their rings. This is very valuable for the study of climate change.

Bristlecone pines often grow in a twisted fashion and one section of the tree may die off several thousand years before another part, making it very difficult to capture the oldest part of the tree in a core sample. The Forest Service granted permission for the researcher to take core samples from several old-looking bristlecone pines and to cut one down to obtain a more accurate count. The tree the researcher selected to cut down was known as Prometheus.

Counting later revealed that Prometheus contained about 4,900 growth rings, making it the oldest living tree ever found. Today, the oldest known living tree, is a 4600 year old bristlecone pine in the White Mountains of California. Count the rings for yourself in the Great Basin Visitor Center! A new permanent exhibit was installed in 2007 featuring a tree ring that was taken from Prometheus in the 1960s.


According to ancient Greek myths, Prometheus was an immortal who brought fire (symbolic of knowledge) to humans. Prometheus the bristlecone pine also imparted much knowledge to humans. Information gained by studying this significant tree added to the knowledge of carbon dating (which is valuable to archeologists and paleontologists) and climate data.

These ancient trees are now protected on federal lands, in part due to the public outcry over the loss of Prometheus. The researcher responsible for cutting down the tree later became one of the strongest advocates for the creation of Great Basin National Park.

U.N. says, Insects are our food of the future

U.N. says, Insects are our food of the future


Nearly 1 billion of Earth's 7 billion humans are already chronically hungry, and there will likely be an additional 2 billion mouths to feed by 2050. But rather than doubling down on traditional efforts to fight hunger, a new United Nations report suggests a more avant-garde approach to feed the world: less beef, more beetles.

Produced by the U.N. Food and Agriculture Organization (FAO), the report advocates insect farming as a win-win way to mitigate the planet's mounting food problems. Not only are insects "nutritious, with high protein, fat and mineral contents," it points out, but they're also extremely low-maintenance compared with most livestock.

"Insects are everywhere and they reproduce quickly," the report says, "and they have high growth and feed conversion rates and a low environmental footprint."

Since they're cold-blooded, bugs don't have to use energy from their feed to maintain body heat. They can make about 1 kilogram (2.2 pounds) of insect meat for every 2 kg of feed, while cows need 8 kg (17.6 lbs.) of feed just to make 1 kg of beef. Warm-blooded livestock also need more water and land, and they pollute their environment with bacteria-laden feces and noxious flatulence — including methane, a potent greenhouse gas. Insects, on the other hand, actually break down waste and can help return nutrients to the soil.

This is old news in some places, as the FAO acknowledges, since humans already eat more than 1,900 different insect species worldwide. The most commonly eaten insects are beetles (31 percent); caterpillars (18 percent); bees, wasps and ants (14 percent); and grasshoppers, locusts and crickets (13 percent). These may seem like paltry provisions next to a hamburger, but the FAO points out insects are often a better source of protein and nutrients. Beef has an iron content of 6 milligrams per 100 grams of dry weight, for example, while locusts offer between 8 and 20 mg per 100 g of dry weight.

Still, the U.N. knows insects are a hard sell in Western nations, so it's taking a measured tone. "We are not saying that people should be eating bugs," says Eva Muller, director of FAO's Forest Economic Policy and Products Division, in a statement on how forests can fight hunger. "We are saying that insects are just one resource provided by forests, and insects are pretty much untapped for their potential for food, and especially for feed."

The FAO kind of is saying people should eat bugs, though, just not everyone all at once. "The polarity of views surrounding the practice of entomophagy necessarily requires tailormade communication approaches," it explains. "In the tropics, where entomophagy is well established, media communication strategies should promote edible insects as valuable sources of nutrition. ... Western societies require tailored media communication strategies and educational programs that address the disgust factor." Locusts in Australia, for instance, sound a little more appetizing when they're called "sky prawns."

The disgust factor isn't the only hurdle for Western insect cuisine. As the FAO notes, most industrialized nations outlaw feeding waste, slurry or swill to livestock, "even though this would be the material that insects normally feed on." They also tend to have regulations against using insects in human food — typically with accidental ingredients in mind — but the report adds that "with a growing number of novel food stores and restaurants cropping up in developed countries, it seems to be largely tolerated."

"The private sector is ready to invest in insect farming. We have huge opportunities before us," says Paul Vantomme, a co-author of the FAO report. "But until there is clarity in the legal sphere, no major business is going to take the risk to invest funds when the laws remains unclear or actually hinders development of this new sector."

More Colorful Than We Ever Thought Mercury

More Colorful Than We Ever Thought Mercury

Image credit: NASA(taken from)

We all know of the planet Mercury being most well known for its position closest to the sun. Mercury speeds around the sun at only 88 times a year making it the fastest planet in our solar system by 31 miles per second. As a matter of fact, it gets as close as 29 million miles away from the sun and can reach temps of upward 800 fahrenheit. The night time temps are extreme as well due to the lack of atmosphere the planet has. Those can reach a nasty -280 Fahrenheit!

What we didn’t know until recent was its true colors, literally. Mercury was always the gray planet closest to the sun. Our universe explorers NASA have a satellite in orbit called Messenger. Messenger is equipt with a multi filtered camera system that allows itself to isolate color variations and combine them for incredible photographs. It can actually perform mineralogical studies from orbit! In the pictures below you can see how Messenger’s pictures differentiate rock types and colors. The yellowish color indicates a younger surface while the blueish color is a more aged surface. The younger surface is obvious due to its lack of impact scares caused by speeding space debris. Astronomers wish these color patterns could be viewed by the bare eye, unfortunately they can only be viewed this way through the Messenger’s camera technologies.

The Messenger was moving at such a high rate of speed that scientists could not decipher the mineral composition in the images. On the upside, Messenger has already settled into orbit in 2011. What this means is now the scientists will be able to map the surface of Mercury to the satellites CPU giving us space junkies even better detail and more info on this beat up, fried planet. We will keep our followers up to date as possible with further images when made available.

Did you know that Bell Peppers have a Gender !


Did you know that Bell Peppers have a Gender !


Did you know you can check the gender of bell peppers? Turn them over...the ones with four bumps are female and those with three bumps are male.
The female peppers are full of seeds, but sweeter and better for eating raw and the males are better for cooking.

Human Brain Analysis - Man vs. Woman

Human Brain Analysis - Man vs. Woman


1. MULTI-TASKING
Women - Multiple process
Womens brains designed to concentrate multiple task at a time.
Women can Watch a TV and Talk over phone and cook.
Men - Single Process
Mens brains designed to concentrate only one work at a time. Men can not watch TV and talk over the phone at the same time. they stop the TV while Talking. They can either watch TV or talk over the phone or cook.

2. LANGUAGE
Women can easily learn many languages. But can not find solutions to problems. Men can not easily learn languages, they can easily solve problems. That's why in average a 3 years old girl has three times higher vocabulary than a 3 yeard old boy.

3. ANALYTICAL SKILLS
Mens brains has a lot of space for handling the analytical process. They can analyze and find the solution for a process and design a map of a building easily. But If a complex map is viewed by women, they can not understand it. Women can not understand the details of a map easily, For them it is just a dump of lines on a paper.

4. CAR DRIVING.
While driving a car, mans analytical spaces are used in his brain. He can drive a car fastly. If he sees an object at long distance, immediately his brain classifies the object (bus or van or car) direction and speed of the object and he drives accordingly. Where woman take a long time to recognize the object direction/ speed. Mans single process mind stops the audio in the car (if any), then concentrates only on driving.

5. LYING
When men lie to women face to face, they get caught easily. Womans super natural brain observes facial expression 70%, body language 20% and words coming from the mouth 10%. Mens brain does not have this. Women easily lie to men face to face.
So guys, do not lie face to face.

6. PROBLEMS SOLVING
If a man have a lot of problems, his brain clearly classifies the problems and puts them in individual rooms in the brain and then finds the solution one by one. You can see many guys looking at the sky for a long time. If a woman has a lot of problems, her brain can not classify the problems. she wants some one to hear that. After telling everything to a person she goes happily to bed. She does not worry about the problems being solved or not.

7. WHAT THEY WANT
Men want status, success, solutions, big process, etc... But Women want relationship, friends, family, etc...

8. UNHAPPINESS
If women are unhappy with their relations, they can not concentrate on their work. If men are unhappy with their work, they can not concentrate on the relations.

9. SPEECH
Women use indirect language in speech. But Men use direct language.


10. HANDLING EMOTION
Women talk a lot without thinking. Men act a lot without thinking.
