Strawberries are even higher in vitamin C than oranges, with eight medium strawberries containing 160 percent of your recommended daily value (60 mg)! A medium orange contains 74 milligrams of Vitamin C, while eight average-sized strawberries provide about 96 mg. Another added benefit is that strawberries are also low in calories - just 50 per eight-strawberry serving.

John Walker was an Englishman born in 1781. He became a surgeon’s assistant but found that he was too squeamish to deal with surgical operations and turned to chemistry instead. He became keenly interested in finding a way of obtaining fire easily. Back then it was not yet possible to transfer a flame onto a slow burning substance, like wood.
One day he was experimenting with a mixture of sulphide of antimony, chlorate of potash, and gum. He stirred it with a wooden splint coated in sulphur. The splint caught fire upon accidental friction against the hearth, and that is how he accidentally invented friction matches.
The price of a box of 50 matches was one shilling. With each box was supplied a piece of sandpaper, folded double, through which the match had to be drawn to ignite it. He refused to patent his invention and everybody was free to make them.
In 1829 Isaac Holden independently arrived at the same idea. By that time Walker had sold no less than 250 boxes of friction matches, as recorded in his sales book. Walker never became famous or rich from his invention and was only credited for it after his death in 1852.
Finding huge, significant archeological sites doesn't always have to leave you digging in the mud for months on end. Sometimes it shows up out of nowhere, by accident. In 1982 right outside the Titusville, Florida city limits, a backhoe operator discovered very old human remains.
Turns out the bones were about 7,000 years old. They belonged a little girl who was still clutching her favorite toys: a wooden pestle-shaped object and the carapace of a small turtle. That doesn't necessarily mean the bones look their age. At first, archeologists thought they were only a few hundred years old due to their keen preservation. Radiocarbon dating proved that incorrect.
Inside the skull, a dark brown, slippery material was found. After some analysis scientists learned that it was preserved brain tissue. Other skulls contained complete brains. The tissue was taken from the skulls and placed in plastic bags flooded with nitrogen gas for DNA cloning.
From the first day of excavation it became apparent that the site was one of the most intact cemeteries of 6,000 B.C.
Some awesome lists!
A rare genetic disorder could be the key to unlocking cancer-fighting drugs. These small people revealed something big!
Endocrinologists have stumbled upon a rare form of dwarfism that may prove helpful in the fight against cancer. Largo syndrome differs from other types of dwarfism. Usually people with dwarfism lack growth hormones, but people with Laron syndrome have too much of the hormone. Their cells just do not respond to growth hormones. This protects them against DNA damage that fuels cancer growth.
Arlan Rosenbloom has been studying a cluster of people in Ecuador who all have this rare genetic defect. His investigation has led to one of the most remarkable discoveries ever made in modern endocrinology: a concentrated population of individuals virtually immune to cancer!
Endocrinologist Guevara-Aguirre met people with this type of dwarfism, discussed their histories, and read their records and discovered that none of them got cancer. He conducted an in-depth investigation, comparing cancer rates in the Laron syndrome patients with those of their relatives of normal height. After five years of laboratory experiments and analysis they reported that, out of of 99 Laron syndrome cases, only one case of cancer existed on record—and that patient had survived!
The first step in turning the lessons of Laron syndrome into anticancer drugs has been taken. In 2008 Dr. Longo founded DSR Pharmaceuticals to develop a pill that blocks the growth hormone receptor.
Your achy joins and muscles yearn for a small dose of Tylenol which is full of acetaminophen, the active drug that eases the pain. Unfortunately it's also the most commonly overdosed substance and accounts for a large amount of liver failures. Fortunately, it has a second function for when you're feeling especially rejected.
2009 research at the University of Kentucky shows that the power of acetaminophen doesn't alter your mental state, so you're able to drive a car and go to work, but it does dull the pain of social rejection, similar to alcohol. Social rejection can damage a person's health as much as smoking or obesity. And, that hurts.
Apparently, physical pain and social rejection have a common neural process and subjective component that experience distress. That feeling of a lack of purpose or uncertainty in life can actually lead to physical pain. Tylenol manages to block that unease the same way it stops pain, by affecting and blocking that neurological process.
It's not recommended you run out and buy up the drug store's stock of Tylenol for when you're feeling a little down. Too much of the stuff is still harmful and should be used sparingly to treat pain, physical that is.
