Article: Researchers are now using 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation. Dr. Bramlet, a children's heart expert at the University of Illinois College of Medicine, says the 3-D models show information he cannot get any other way. "And so what we've done with the printed models? We've pulled it out of the screen so that you can actually hold it in your hand and evaluate the anatomy ." A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model to understand the anatomy. Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail. "When we're done with the model and made our decision, we want to be able to go back to the source image and confirm those findings," he says. Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby's heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations. Kathy Magliato is a heart surgeon at Saint John's Health Center in Los Angeles. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients. "I can then take this very complicated structure before the operation and I can hold it in my hand and plan an operation around what I'm seeing, touching and feeling. That to me is what can potentially change the game in an operation and save lives." Dr Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.

Article: Borrowing to start a business is not easy. Getting a bank loan, particularly for a new small business, is _ Banks favor established-business people with a solid credit rating and a large bank account. They should also have experience in the business they propose to enter, and offer well-prepared business plans that show the ability to repay the loans. If you are not such a person, then you need to double your preparations to convince the banker to lend you that much needed start-up capital . If your business is new and small, bankers will need to know as much as possible about you and your business. However, many small business owners often make the mistake of not being well prepared when going to the bank to apply for the loan. Surprisingly, many loan applicants don't even have the slightest idea how or when they intend to repay the money they request. Often they don't even know how much money they need. When asked how much money they want to borrow, many people give these two common responses: "How much money can I get?" and "As much as possible." Is it any wonder that lenders say no? So the most important thing is do your homework before you ask for a loan.

Article: Elephants scored a big win in 2010. Representatives from 175 countries at the United Nations' Convention on the International Trade in Endangered Species (CITES) in Doha, Qatar, rejected a bid to allow the sale of ivory. Two African nations, Tanzania and Zambia, had asked to open the ivory trade. Conservationists feared that weakening a 21-year-old ban on the sale of ivory would have encouraged illegal hunting and hurt elephant populations. African elephants once numbered in the millions. Today, there are fewer than 500,000. "People born in 100 years should be able to see an elephant, " said Noah Wekesa, Kenya's minister of forestry and wildlife. His country voted to keep the ban. In the 1980s, as many as one million elephants were killed throughout Africa. Hunters killed the animals for their ivory tusks, which were used to make jewelry and other items. " The slaughter of elephants in Africa was just terrible, " says Paul Todd of the International Fund for Animal Welfare ( IFAW ). The group works to protect animals. The ivory wars continued until 1989, when CITES voted to ban all trade in ivory. With trade controlled, demand for ivory fell. Elephant populations began to increase slowly. Tanzania and Zambia asked CITES to allow ivory sales from government stockpiles . Ivory is so expensive that it's known as "white gold". Tanzania holds almost 200,000 pounds of ivory, which is worth as much as $20 million. Zambia has 48,000 pounds of the "white gold". The two countries argued that their ivory had been taken from hunters or had come from animals that died naturally. They said this income from the sale of ivory would help the countries. Wildlife experts, who believe that the ivory trade encourages illegal hunting, cheered the CITES decision. "It's a rare victory for elephants," said Jason Bell-Leask, the IFAW's director for southern Africa.
