Warm People Likely to Keep Cold at Bay1
Staying positive2 through the cold season could be your best defense against getting ill，new study findings suggest. In an experiment that.exposed healthy volunteers to a cold or flu virus3, researchers found that people with a generally sunny disposition4 were less likely to fall ill.
The findings, published in the journal Psychosomatic Medicine, build on evidence that a "positive emotional style”5 can help ward off the common cold and other illnesses. Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less troubled by a scratchy throat6 or runny nose.
"People with a positive emotional style may have different immune responses to the virus，，’ explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. “ And when they do get a cold, they may interpret their illness as being less severe. ”
Cohen and his colleagues had found in a previous study that happier people seemed less Susceptible to7 catching a cold, but some questions remained as to8 whether the emotional trait itself had the effect.
For the new study, the researchers had 193 healthy adults complete standard measures of personality traits, self-perceived health and emotional "style". Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy，tense and hostile had a negative style.
The researchers gave them nasal drops containing either a cold virus or a particular flu virus. Over the next six days，the volunteers reported on any aches，pains，sneezing or congestion they had, while the researchers collected objective data, like daily mucus production. Cohen and his colleagues found that based on objective measures of nasal woes, happy people were less likely to develop a cold.

Sauna
Ceremonial bathing1 has existed for thousands of years and has many forms, one of which is the sauna. The Finns have perfected the steam bath，or sauna, which may be taken, usually in an enclosed room, by pouring water over hot rocks or as a dry heat bath. The Japanese, Greeks, Turks and Russians as well as Native Americans have forms of the sweat bath in their bathing rituals. Dry heat and steam baths had advocates in ancient Romeand" pre-Columbian Americans2 used sweat lodges.
The earliest saunas were probably underground caves heated by a fire that naturally filled with smoke as chimney making was unknown at that time. A fire kept in a fire-pit3 would heat the rock walls of the cave. After reaching full heat, the smoke was let out of the cave and the stones would retain heat for several hours. A few people today say that the smoke sauna, “ savusauna”，is the only true sauna experience and that all saunas should have at least a background odor or smoke. Today most saunas use electric stoves, although gas and wood-burning stoves are available.
Saunas are relaxing and stress relieving4, Those with muscle aches or arthritis may find that the heat relaxes muscles and relieves pain and inflammation. Asthma patients find that the heat enlarges air passageways of the lung and facilitates breathing. Saunas do not cure the common cold but they may help to alleviate congestion arid speed recovery time5. The body’s core temperature usually rises a 1-2 degrees while in the sauna, thus imitating6 a slight fever7. The sauna could be considered to follow the old saying “feed a cold，starve a fever" The regular use of a sauna may decrease the likelihood of getting a cold in the first place.
Sauna is good for your skin as the blood flow to the skin increases and sweating occurs. Adults sweat about 2 lbs8 of water per hour on average in a sauna. A good sweat removes dirt and grime from pores and gives the skin a healthy glow. The loss in water weight is temporary as the body"s physiological mechanisms will quickly restore proper volumes. The cardiovascular system9 gets a work out10 as the heart must pump harder and faster to move blood to the surface for heat exchange. Heart rate may increase from 72 beats per minute on average to 100-150 beats per minute.
A normal heart can handle these stresses but those with heart trouble wishing to begin to use a sauna should seek a doctor"s advice. The elderly and those with diabetes should check with their doctor prior to beginning to take saunas. Pregnant women should not take saunas, particularly in the first three months. Indeed, everyone just starting out should take short sessions11 at first to become accustomed to this type of bath.

The Barbie Dolls
In the mid一1940"s, the young ambitious duo Ruth and Elliot Handler, owned a company that made wooden pictures frames. It was in 1945 that Ruth and Elliot Handler joined with their close friend Harold Mattson to form a company that would be known for the most famous and successful doll ever created. This company would be named MATTEL, MATT for Mattson ,and EL for Elliot 1.
In the mid—1950"s, while visiting Switzerland, Ruth Handler purchased a German Lilli doll. Lulll was a shapely 2, pretty fashion doll first made in 1955.She was originally fashioned after a famous cartoon character in the West German Newsletter, Build.
Lilli is the doll that would inspire Ruth Handler to design the Barbie doll. With the help of her technicians and engineers at Mattel, Barbie was born. Ruth then hired Charlotte Johnson, a fashion designer, to create Barbie"s wardrobe. It was in 1958 that the patent for Barbie was obtained. This would be a fashion doll unlike any of her time. She would be long limbed ,shapely , beautiful ,and only 11.5 inches tall. Ruth and Elliot would name their new fashion doll after their own daughter, Barbie 3.
In 1959 ,the Barbie doll would make her way to the New York Toy Show and receive a cool reception from the toy buyers.
Barbie has undergone a lot of changes over the years and has managed to keep up with current trends in hairstyles, makeup and clothing. She is a reflection of the history of fashion since her introduction to the toy market.
Barbie has a universal appeal and collectors both young and old enjoy time spent and memories made with their dolls.

The Sahara
The nameSaharaderives from the Arabic word for "desert" or "steppe". At 3. 5 million square miles，an area roughly the size of the United States，the Sahara Desert in northern Africa is the largest desert in the world. lt spans the continent from theAtlantic Oceanto theRed Sea. Daytime temperatures can reach as high as 130°F. The humidity sometimes gets into the teens. But it can also be as low as 2. 5 percent，the lowest in the world. Most of the Sahara receives less than five inches of rain per year，while large areas sometimes have no rainfall at all for years.
At the heart of the Sahara is the landlocked north African country ofNiger. Here the sand dunes can be 100 feet tall and several miles long. Here sand plains stretch over an area larger thanGermanywhere there is neither water nor towns. Yet sitting in the midst of the surrounding desert is the town ofBilma. Suddenly there are pools of cIear water. Surprisingly，there are groves of date palms. Underground water resources，or oases，sufficient to support irrigated agriculture are found in dry stream beds and depressions. 1Irrigation ditches run off a creek to water fields. 2 Corn，cassava，tea，peanuts，hot peppers，and orange，lime，and grapefruit trees grow in these fields. Donkeys and goats graze on green grass. 3
The Sahara of Niger is still a region where you can see a camel caravan of 500 camels tied together in loose lines as long as a mile，traveling toward such oasis towns. There a caravan will collect life-sustaining salt，which is mined from watery basins，and transport it up to 400 miles back to settlements on the edges of the desert. The round trip across the vast sands takes one month.

Defending the Theory of Evolution 1 Still Seems Needed
Judith S. Weis, a biology professor who serves as 2 president of the American Institute of Biological Sciences (AIBS) is leading a nationwide effort to “defend，，the theory of evolution. Weis leads the effort in the face of what the institute views as opposition and indifference from school boards and government entities 3.
The Institute believes that the teaching of evolution in Americais being diminished by the teaching of creationism as well as by an overall lack of teachingDarwin"s 4 theory in high school. "There"s nothing that requires schools to teach evolution. Sometimes teachers in high schools just leave it out 5 . However, from the point of view of biologists, evolution is the central theory of biology upon which everything is based," said Weis. "Unfortunately, teaching evolution has become a political issue in many parts of the country and AIBS, as a representative of biologists, wanted to be a major force speaking out in favor of its teaching." 6
Weis said the institute is working together with the American Geological Institute and the National Association of Biology Teachers and its 80-plus member organizations 7 to address 8 the political and legislative threats to teaching evolution. In states challenging its teaching, the institute responds by sending letters to school boards and state legislatures, by providing testimony at public meetings and by notifying members and affiliated organizations. AIBS, with more than 80 member societies and 250,000 members, has established an e-mail system enabling scientists and teachers in each state, and member societies, to keep each other informed about threats to the teaching of evolution.
Darwin"s theory of evolution holds that living things change and adapt to their environment and that present-day species (including human beings) are descended from earlier species through modification by natural selection. The theory has been accepted by scientists for nearly 100 years, Weis said, and has been refined, extended and strengthened over the years by findings in paleontology and developmental biology.
Discoveries in genetics, molecular biology 9 and genomics — all of which provide significant benefits for human health — would not be possible without the underlying 10 knowledge of evolution. And, Weis adds, "modern molecular biology and genomics have increased our understanding of how evolution works." Nonetheless, evolution remains a politically, if not scientifically, controversial issue.
Weis said that this year alone, seven states have had either local or statewide efforts to water down 11 the teaching of evolution, or "balance" it with the teaching of creationism 一 a religious belief that different species were created separately by a higher power, such as God. "Rarely does anyone now use the word ‘creationism，，because that"s too obvious," Weis said. "The current terminology is ‘intelligent design.
