Gene-edited farm animals are on their way

Gene-edited farm animals are on their way

Science
Scientists have created pigs that are immune to one of the world's costliest livestock diseases.The team edited the animals' DNA to make them resist the deadly respiratory disease known as PRRS - a move that could prevent billions of pounds in losses each year.However, consumers have traditionally been reluctant to eat genetically altered animals and crops.This poses a significant barrier to farmers owning gene-edited pigs.And because genome, or gene, editing (GE) is relatively new, the absence of regulation currently prevents their sale anyway.GE is different to the more widely used technology of genetic modification. The former involves the precise alteration of an organism's DNA, while the latter is characterised by the introduction of foreign genetic ...
How many animals are born in the world every day?

How many animals are born in the world every day?

Science
Birds do it, bees do it, even educated fleas do it - well, maybe they don't fall in love but they do procreate, so can we estimate how many animals are born every day across the world? That was the question posed by a listener to the BBC's More or Less programme, a show which aims to make sense of the numbers that inform our lives.First things first, what do we mean by the term "animal"? The Oxford English Dictionary defines an animal as "a living organism which feeds on organic matter, typically having specialised sense organs and nervous system and able to respond rapidly to stimuli".So that's mammals and non-mammals, vertebrates and invertebrates, animals that hatch, and animals that have live births. ...

To teach kids morals, read books with humans not animals

Science
Aug. 18 (UPI) -- Anthropomorphic, or human-like, animals are often the protagonists of children's books. But new research suggests parents who want their kids to pick up on a story's moral lessons should choose books featuring humans, not animals.Researchers in Canada found four to six-year-olds were more likely to share with their peers after being read a story with human characters."Many people believe children find stories with human-like animals captivating and relatable, but what we're finding is that this is not the case," Dr. Patricia Ganea, associate professor of early cognitive development at the University of Toronto, said in a news release. "Overall, children were more likely to act on the moral of the story when it featured a human character."Researchers read stories about shar...
Arctic voyage finds global warming impact on ice, animals

Arctic voyage finds global warming impact on ice, animals

The email arrived in mid-June, seeking to explode any notion that global warming might turn our Arctic expedition into a summer cruise. "The most important piece of clothing to pack is good, sturdy and warm boots. There is going to be snow and ice on the deck of the icebreaker," it read. "Quality boots are key." The Associated Press was joining international researchers on a month-long, 10,000 kilometer (6,200-mile) journey to document the impact of climate change on the forbidding ice and frigid waters of the Far North. But once the ship entered the fabled Northwest Passage between the Atlantic and the Pacific, there would be nowhere to stop for supplies, no port to shelter in and no help for hundreds of miles if things went wrong. A change in the weather might cause the mercury to drop ...

FLYING can be a stressful and nerve-wracking experience. For those with mental-health issues it must be doubly so. One way in which vulnerable travellers deal with their anxiety on a plane is to take on board an “emotional support animal” (ESA). Such creatures provide succour for their owners. Unlike guide dogs, they “do not require any kind of specialised training,”  according to CertaPet, an organisation that provides such services. “In fact,” reckons CertaPet, “very little training is required at all, provided that the animal in question is reasonably well behaved by normal standards.”That sounds like an easy and effective way to help sufferers. It was distressing to read, therefore, of the emotional support dog that mauled a passenger on Delta flight from Atlanta to San Diego earlier t
