[Q]: Article: Older fathers have uglier children, researchers have claimed after linking age to genetic mutations . The finding comes weeks after leading scientists reported children born to men over the age of 45 run a higher risk of having autism and mental disorders. With age, sperm -producing cells do not copy a man's DNA as effectively, leading to genetic mutations. Martin Fielder, an anthropologist at Vienna University, told the Sunday Times: 'Every 16 years the mutation rate doubles. Other researchers found 25 mutations per sperm in a 20-year-old, but at age 40 it is 65 mutations. By 56, it doubles again. The effect is very visible - someone born to a father of 22 is already 5-10 per cent more attractive than those with a 40-year-old father and the difference grows with the age gap. In contrast, women pass on a maximum of 15 mutations to their baby, regardless of age, according to the study published in the journal Nature. Surveying a group of six men and six women, researchers showed them each 4,018 photographs of 18-20-year-old men and 4,416 of women the same age, and asked to assess their attractiveness. Those with older fathers were consistently considered less attractive. However, the children of older men, though less attractive, are likely to outlive their peers with younger fathers, it is claimed. Professor Lee Smith, a geneticist at Edinburgh University, told the Sunday Times other research found such children have longer telomeres - the caps on the end of chromosomes --- which are associated with longer life. But the mounting research connecting parents' age with autism is cause for concern, experts warn. Autism is an umbrella term for a range of developmental disorders that have a lifelong effect on someone's ability to interact socially and communicate openly. In the UK, around one in 100 adults is thought to be affected by autism, mostly men, caused by a combination of genetic and environmental factors. Researchers said men should be advised about the potential problems in order to help their personal decision-making when it came to having fathering children at older ages. They warned that advancing paternal age faced a risk of 'numerous public health and societal problems'. Among well-known older dads are Simon Cowell, 54, whose son was born earlier this month, and comedian Frank Skinner whose first child was born in 2012 when he was 55.

[Q]: Article: DALLAS - A suburban Dallas woman accused of killing her two young children told a 911 operator that she first tried to poison them because they were autistic and she wanted "normal kids," then choked them with a wire until they stopped moving, according to the recorded call. Irving police on Wednesday released recordings of the 911 call after Saiqa Akhter was charged with capital murder in the death of her 5-year-old son, Zain Akhter and her 2-year-old daughter, Faryaal Akhter. Police said the children were attacked at the family's apartment Monday night. In the recording released Wednesday, the woman identified herself as Saiqa Akhter and repeatedly told the operator she killed her two children. At one point, the woman hung up and the dispatcher called her back. "I killed both of them. I told you," she told the operator. Later, she explained that both children were lying motionless on the bed in the master bedroom. "They are not doing anything. They are just blue and they are not taking any breaths and ... their heart is not beating," she said. She told the operator she initially tried to poison the children with bathroom cleaner but they refused to drink it. When that didn't work, "I used a wire on their necks," she said. When the operator asked the woman why she attacked her children, she said, "They're both not normal, not normal. They're autistic. Both are autistic." Pressed further, she said, "I don't want my children to be like that. ... I want normal kids." Later, the dispatcher asked the woman what she was feeling. "Nothing," she responded. At one point, water could be heard running in the background and the dispatcher asked what the woman what she was doing. She told the operator she was trying to wash the smell of cleaner off of her hands. The dispatcher then told the woman to go sit on a couch in the living room and wait for police. At the end of the recording, police can be heard arriving at the home.

[Q]: Article: Why did the chicken cross the road? To get to the other side. Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road. " Millions of animals die each year on the U. S. roads, " the Federal Highway Administration reports. In fact, only about 80 ocelots , an endangered wild cat, exist in the U. S. today. The main reason? Roadkill. "Eco-passages" may help animals cross the road without being hit by cars. They are paths both over and under roads. " These ecopassages can be extremely useful,so that wildlife can avoid road accidents ," said Jodi Hilty of the Wildlife Protection Society. But do animals actually use the eco-passages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway. This showed that the lions used the passage. Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders and grizzly bears are using the bridges and underpasses. The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal over-pass !
