Imagine an industry that runs out of raw materials. Companies go bankrupt, workers are laid off, families suffer and associated organizations are thrown into turmoil. Eventually, governments are forced to take drastic action. Welcome to global banking, recently brought to its knees by the interruption of its lifeblood – the flow of cash. In this case, we seem to have been fortunate. In the nick of time, governments released reserves in order to start cash circulating again. But what if the reserves had not been there? What are we going to do when our supplies of vital materials such as fish, tropical hardwoods, metals like indium and fresh water dry up? We live on a planet with finite resources – that is no surprise to anyone – so why do we have an economic system in which all that matters is growth – more growth means using more resources. When the human population was counted in millions and resources were sparse, people could simply move to new pastures. However, with 9 billion people expected around 2050, moving on is not an option. As politicians reconstruct the global economy, they should take heed. If we are to leave any kind of planet to our children, we need an economic system that lets us live within our means.

Man, through the ages, has undergone many changes from the time WHEN he depicted a herd of mammoths on the walls of his cave to these days WHEN he can create beautiful pictures AND even make coffee by use of computer technologies WITHOUT leaving his favorite chair. The 20th century made huge steps in developing computer technologies AND reached many goals THAT made our life much easier. WHAT should we expect in the 21st century? First of all, I think THAT the pace of our life will speed up: we will move faster from one place to another, from one continent to another using high speed jet airplanes. Second of all, I believe THAT we will be able to do many things THAT take much time now WITHOUT leaving our house. Computers will be everywhere INCLUDING our clothes. Many people will have chips AND mini computers inserted in their heads to hold huge amount of information AND have a quick access to it.

(I) One of the oldest methods of preserving food is drying. (II) It slows down the proliferation and activity of the bacteria that cause spoilage and decay, but it considerably alters the appearance of food due to the loss of water. (III) With the success of freezing and its characteristics for retaining the food value of ingredients, drying is no longer an essential means of preserving food for times when it may be out of season or expensive. (IV) Since prehistoric times, cereals and fruits have been dried in the sun before being stored. (V) The drying of fruits and vegetables has been widely practiced for so long

Why Chocolate Can Be Deadly For Dogs Chocolate is a sweet treat for many people, but for dogs it can be a killer. The message, from the U.S. Food and Drug Administration, is especially important now because chocolates from Easter may still be in many homes. Chocolate contains a substance called theobromine that is similar to caffeine and is toxic to dogs at certain levels. The minimum amount of theobromine dangerous to dogs ranges from 46 to 68 milligrams per pound (mg/lb), according to the FDA’s Center for Veterinary Medicine. Half the dogs that consume 114 to 228 mg/lb or more of theobromine will die. A number of factors determine whether a dog will have a toxic reaction, including its size, the amount of chocolate the dog ate, and whether it is extra sensitive to theobromine, the agency said in a news release. The type of chocolate is also important. The amounts of theobromine present are: 704 mg/lb in milk chocolate, 2,400 mg/lb in semisweet chocolate, and 6,240 mg/lb in baking chocolate. To get 46 mg/lb of theobromine, a dog would have to eat: 1 ounce per 1 pound of its body weight of milk chocolate

4. The poll revealed that 14 percent believe that Bigfoot is real. Another 14 percent said they were not sure, while 72 percent said they do not believe Bigfoot is real. Reality Check: Despite several attempts to prove Bigfoot exists, no one has presented evidence that has withstood scientific scrutiny. Indeed, many such "proofs" have turned out to be outright hoaxes. In 2008, two men claimed to have found a seven-foot (two-meter) tall, 500-pound (230-kilogram) Bigfoot corpse in the woods of northern Georgia, but the body was later revealed to be a rubber ape costume. Last November, another group claimed they had done DNA tests that proved the "North American Sasquatch is a hybrid species, the result of males of an unknown hominin species crossing with female Homo sapiens." The researchers touted the fact that their study was published in a scientific journal called DeNovo—but it seems the publication was created especially for that Bigfoot study. While Bigfoot is likely just a myth, that's not to say that no new, close relatives of humans have ever been found—it's just that all of them are long extinct. For example, in 2010, scientists announced that a 40,000-year-old pinkie bone found in a Siberian cave belonged to a previously unknown species of ancient human called Denisovans. 5. Some 9 percent believe the government adds fluoride to drinking water for "sinister" purposes. Reality Check: The latest evidence that fluoridated water has dental health benefits comes from a 2013 study published in the Journal of Dental Research. The study found that fluoride in drinking water prevents tooth decay in adults regardless of age, whether or not they drank fluoridated water as children. Other recent evidence of the dental benefits of fluoride came from an unlikely source: A survey of more than 23,000 skeletons from medieval archaeological sites in Britain showed that people who lived near the coast—and presumably consumed a lot of fluoride-rich fish—had fewer cavities. 6. A total of 7 percent of voters believe the moon landing was faked. Another 9 percent said they weren't sure whether the Apollo moon landing really happened. Reality Check: Believers of this particular conspiracy theory have painstakingly dissected video and photos from the Apollo 11 moon landing looking for evidence that it was faked. For example, some have pointed out that the American flag Neil Armstrong planted on the moon appears to be flapping "in a breeze" in videos and photographs. But, as spaceflight historian Roger Launius of the Smithsonian's National Air and Space Museum in Washington D.C., explained on the 40th anniversary of the first moon landing, "The video you see where the flag's moving is because the astronaut just placed it there, and the inertia from when they let go kept it moving."

According to PPP, more Americans who supported Mitt Romney for president last year (27 percent) than those who supported Barack Obama (16 percent) believe in the UFO cover-up. Reality Check: It hasn't always been the case, but many astronomers today are open to the idea of life existing elsewhere in the universe—and even to the possibility of intelligent alien life. That's thanks in large part to the relatively recent discoveries of hundreds of so-called exoplanets—worlds beyond our solar system—and thousands of planet candidates. Most scientists think it's only a matter of time before a habitable, rocky, Earth-like twin is discovered. Even our own solar system might contain evidence of alien life. NASA's Curiosity rover recently discovered tantalizing evidence of clays and minerals that scientists say could only have formed in water. The implication: Ancient Mars had the conditions and ingredients necessary to support life. As for UFOs, most sightings are eventually linked to more mundane causes. For example, a recent video by actor Russell Crowe purportedly capturing a UFO outside his office was likely reflected sunlight from a plane passing near sunset. 3. Some 20 percent believe childhood vaccines are linked to autism. These voters believe that childhood vaccines against mumps and other diseases could increase the risk of developing autism. Reality Check: A recent government study confirmed what many scientists have been saying all along: There is no connection between the number of vaccines a child receives and his or her risk of developing autism. The study, published last month in The Journal of Pediatrics, also found that even though kids are getting more vaccines these days, those vaccines contain fewer substances that provoke an immune response. 4. The poll revealed that 14 percent believe that Bigfoot is real. Another 14 percent said they were not sure, while 72 percent said they do not believe Bigfoot is real.

Fact Checking 6 Persistent Science Conspiracy Theories Conspiracy theories are as American as apple pie. A national poll released this week by Public Policy Polling (PPP) found that some popular conspiracy theories in the United States have persisted for years, like the belief that a UFO crashed in Roswell, New Mexico, in 1947. Meanwhile, new theories have gained believers, such as the ideas that Saddam Hussein was involved in the 9/11 attacks and that Osama bin Laden is still alive. Perhaps not surprisingly, many of the ideas in the new poll are based on a misunderstanding of science—or a stubborn refusal to acknowledge it. Here's a reality check on some of the science-related conspiracy theories from the survey: 1. A total of 37 percent of American voters believe global warming is a hoax. Most (58 percent) of the people who believe this identified themselves as Republicans. Of those who don't believe global warming is a hoax, 77 percent are Democrats. Reality Check: Numerous scientific studies have confirmed that the Earth is warming and that the rate of warming is increasing. Average temperatures have climbed 1.4°F (0.8°C) around the world since 1880. Much of the temperature increase happened in recent decades, coinciding with a spike of carbon dioxide and other greenhouse gases emitted into the atmosphere as a result of human activity. The effects of global warming on the natural world are equally well documented: Arctic sea ice is now thawing at historic rates, flowers are blooming earlier, and the migration patterns of birds and other animals are changing. 2. A total of 29 percent of voters believe aliens do exist. Another 21 percent believe the U.S. government covered up a UFO crash near Roswell, New Mexico, in 1947. According to PPP, more Americans who supported Mitt Romney for president last year (27 percent) than those who supported Barack Obama (16 percent) believe in the UFO cover-up.

Higher testosterone levels may spur women to take financial gambles that might have bigger payoffs, according to a new study. Testosterone is the principle sex hormone in males, but it's also found in naturally varying levels in women. In both sexes, testosterone enhances competitiveness and dominance, boosts confidence, and reduces fear. To see what effect the hormone has on financial risk taking, scientists asked 500 male and female MBA students at the University of Chicago's Booth Business School to play a computer game that measured aversion to financial risk. "These are people who understand this type of game and who most likely will be players in the financial industry after graduation," said study team member Luigi Zingales, an economist at the University of Chicago. The students were repeatedly given the choice of receiving a fixed amount of money or entering a lottery where the payout was potentially much higher. The researchers took saliva samples to measure the testosterone levels of each participant before and after the experiment. (Watch rugby players being tested for testosterone changes before, during, and after a match.) What the team found is that men were more willing to take risks than women. In fact, the researchers saw a kind of "ceiling effect" in men, in which differences in financial risk-taking tapered off as testosterone levels increased.

An "electronic tongue" that can digitally measure the taste of sweetness has been created, a new study says. The technique uses a postage stamp-size piece of paper dotted with colored pigments. A computer compares scans of the array of dots before and after the paper is wetted with an eyedropper full of liquid. After running dozens of samples of mystery artificial sweeteners dissolved in water or tea, the research team reported that their tongue could pick out the sweetener used with with 100 percent accuracy. But the array only works collectively: No single dot—each made of a tiny gel coated with a pigment that reacts to different sweeteners—detected any single sugar or sugar substitute, according to study leader Kenneth Suslick, a chemistry professor at the University of Illinois at Urbana-Champaign. "It's not like a key that only fits one lock," Suslick said. "That's not the way our tongue works—that's not the way our nose works. And that's not the way this array works." Bitter End The human tongue also detects saltiness, sourness, bitterness, and savoriness. Sourness is just another word for acidity, Suslick said, which any high school chemistry student can test for using litmus paper. Savoriness—also called "umami"—and saltiness can already be measured by handheld devices sensitive to protein levels and sodium and potassium ions. The final dimension of taste that remains to be cracked is bitterness, which is still somewhat of an unknown.

What Happens After Death? Many of us fear death. We believe in death because we have been told we will die. We associate ourselves with the body, and we know that bodies die. But a new scientific theory suggests that death is not the terminal event we think. One well-known aspect of quantum physics is that certain observations cannot be predicted absolutely. Instead, there is a range of possible observations each with a different probability. One mainstream explanation, the “many-worlds” interpretation, states that each of these possible observations corresponds to a different universe (the ‘multiverse’). A new scientific theory – called biocentrism – refines these ideas. There are an infinite number of universes, and everything that could possibly happen occurs in some universe. Death does not exist in any real sense in these scenarios. All possible universes exist simultaneously, regardless of what happens in any of them. Although individual bodies are destined to self-destruct, the alive feeling – the ‘Who am I?’- is just a 20-watt fountain of energy operating in the brain. But this energy doesn’t go away at death. One of the surest axioms of science is that energy never dies

Many years ago, an old woman named Peggy Ford wrote letters to some men. The men were soldiers who were fighting in the Vietnam War. The soldiers were in combat, far way from their home. They missed their families, and they liked to get the letters from Peggy. Peggy also kept the letters that the soldiers wrote back to her. Peggy Ford died more than 30 years ago. Earlier this year, Ford’s children discovered the letters in her attic. They decided to donate the letters to a history museum. The museum is happy to have the letters. They feel that the soldiers’ stories of the war are valuable. They tell the story of the war better than anyone else could. The museum feels that it’s important to remember the war. The letters show a personal perspective of the war. They are a valuable part of history. A news station filmed a story about Peggy Ford and the letters. The story was posted on the internet. Many people saw the story, and read about Ford’s letters to the soldiers. The story made other people want to donate letters. Many people called the museum. They offered to donate their letters from that era. One woman gave the museum more than 200 letters that she wrote to her husband while he was stationed in Vietnam. She had saved them for many years. She thought others would be interested in them. Peggy Ford was a kind, caring woman. Her letters to the soldiers made them feel better. One woman thinks Ford is an inspiration. She is urging others to write to soldiers in Iraq. She says that a letter would bring a smile to a soldier’s face. Cookies and other treats could be sent with the letters. Small gifts and letters would make the soldiers feel better. She plans to write many letters to soldiers, just as Ford did many years ago. She believes that it’s important to say thank you to the soldiers. She thinks the letters would be a good way to do that. She knows that the soldiers appreciate the letters. The history museum is still interested in Vietnam-era letters written to or from soldiers. The workers there suggest that people contact their local history center or museum if they have similar letters. Letters like Peggy Ford's are considered pieces of history. They tell us about a time in history by the the people living through it.
