Article: Does solving a math problem give you a headache? Doyou feel nervous when you sit a math exam? For most students, math can be tough but scientists have proved that math problems can actually trigger physical pain. Scientists came to his conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fearmath. Those involved were asked a series of questions such as how they feel when they receive amathtextbook orwhenthey walkinto amathlesson. Based on their answers, participants were divided into groups. One group was made up of peoplewhowere particularly afraid ofmath and participantsinthe other group weremore comfortablewiththesubject. Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue squarewould beshown. Using a brain-scan machine, scientists noticed that whenever people from Group One saw ayellow circle, their brain would respond in a way similar to when their bodyis feeling pain. It waslike the pain they would fee, for example, if they burnt their hand on a hot stove. But theyreactedlessstrongly whenthey knew that they would befaced with awordtask. However, scientistssaw no strong brainresponsefrom peopleinthesecond group. Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. "When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong," explained Ian Lyons from University of Chicago, US, leader of the study. "The higher a person's anxiety of a maths task, the more he activated brain regions associated with threat detection, andthe experience of pain." More interestingly, the brain activity disappeared when participants actually started dealingwiththemathtasks. "This means that it'snot that mathitself hurts; rather, the anticipation...

Article: (CBS/AP)Lawyers for the stepfather of an 11-year-old girl tried to convince Massachusetts' highest court on Tuesday that he should have a say on whether his stepdaughter is removed from life support. If the girl dies, Jason Strickland could face a murder charge for illegally taking part in the beating that left her comatose . Jason Strickland is asking the court to overturn a juvenile court judge's decision allowing the state to remove Haleigh Poutre from her ventilator and feeding tube. Haleigh Poutre was hospitalized in September after her stepfather and adoptive mother kicked her and beat her nearly to death with a baseball bat. Within two weeks of being charged, the adoptive mother, who was also Haleigh's aunt, was found dead. Strickland is free on bail while awaiting trial. Sharyn Alfonsi from CBS reports that the girl's biological mother, Allison Avrett, gave up her parental right years ago and now she has no say in what happens to Halleigh--but she wants life support to be relieved. "I want her to rest," Avrett told Alfonsi."Being kept alive like that, it's not a life." The state Department of Social Services wants to remove her from life support, according to opinions from her doctors that the girl is in a permanent vegetative state.And Strickland could face a murder charge if she dies. Both of Haleigh's doctors agree that she should be removed from the ventilator, but they can't decide whether her feeding tube should be disconnected.They have said that with her feeding tube alone, Haleigh could live as long as two months. Haleigh was adopted by her aunt about five years ago her biological mother moved to Virginia with a new boyfriend.Jason Strickland never formally adopted the girl, but is arguing that as the stepfather, he should be a _ parent and allowed to have a say in whether she lives or dies.

Article: Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a physical object.This is now possible with the help of 3D printers.Such machines were once used just by universities and big companies.But now, stores with 3D printing services are appearing around the United States. Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago.The store is filled with tools like a laser cutter, an industrial sewing machine and 3D printers.Bryan Jaycox requires $ 15 an hour to print an object.He also charges a fee depending on the size of the object and up to $ 50 an hour for design and labor services. The Jaycoxs also offer 3D printing classes for anyone who is interested.One of the students in a recent class was Ki Chong Tran.He plans to open a 3D printing business in Cambodia."The demand has been amazing.It's been much more than I would have imagined," said Ki Chong Tran. "I think 3D printing is going to be huge. It's going to make a huge impact on society as a whole," he added. Mr Jaycox predicts that within five years, 3D printing technology could become more consumer friendly. But Ki Chong Tran says even current technology can make a difference in a developing country like Cambodia."With 3D printing you can give them tools, and you put it in their hands so they are responsible more for their own development. They learn skills beyond just learning English and becoming a tour guide or something like that or working at a bank.You can actually create things that give value to the world," said Ki Chong Tran. He says it's not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality. Question: In Mr Jaycox's opinion, within five years 3D printing will _ . Yes or no, is the answer "be accessible to all consumers"?
