Chinese Scientist Claims to Have Created the World’s First Genetically Edited Babies

Chinese researcher He Jiankui recently shocked the entire world after revealing that he had altered the DNA of twin girl before birth, to make them immune to the HIV virus and AIDS. If his claims prove to be true, these twins would be the world’s first genetically-edited babies.

Professor He revealed his controversial genetic editing work earlier this week. In a video posted on YouTube, he claims to have used gene-editing tools to eliminate a gene called CCR5 in order to make a pair of twin girls, called Lulu and Nana, resistant to the HIV virus, should they ever come in contact with it. Speaking at a genome summit in Hong Kong, on Wednesday, the Chinese scientist defended his work and talked about the stigma attached to HIV/Aids in China. However, many of his peers believe that He Jiankui has gone too far, warning that meddling with the genome of an embryo could cause long-term problems not only for the individual, but entire future generations.

Belgian Blue Cattle – Bodybuilders of the Bovine World

Belgian Blue cattle may look like they’ve spent most of their lives pumping iron, but they owe their double muscle characteristics to years of careful breeding and genetics.

Like the name implies, this incredible bred of cattle originated in Belgium. In the second half of the 19th century, Shorthorn bulls from the United Kingdom were sent to Belgium to improve the muscle structure of the native cattle population, which was mostly of the dairy type. Until the 1960s, a balanced animal, which provided average quantities of milk and had averagely lean meat was desired, but in response to the demands of the meat industry and the general economic climate, the Belgian Blue began being bread for its meat. This is when the “double muscling” breakthrough was achieved, after farmers began breeding their most muscular animals to each other. The size of its muscles, low fat and especially the tenderness of the meat made the Belgian Blue a very popular breed.

Some people believe “double muscling” means these cattle have two of every muscle, but that isn’t the case. The term refers only to the size of each muscle, meaning that muscles of Belgian Blue cows and bulls are at least twice as developed as normal cow muscles. Genetic scientists have managed to achieve this by “breaking” the gene that controls the secretion of Myostatin – a protein that inhibits muscle growth after a certain point of development. By suppressing the production of Myostatin, they’ve created a kind of Arnold Schwarzenegger of the animal world.

If you’re having trouble understanding just how big and muscular these animals are, you should know some bulls weigh over a tonne. And to think that’s mostly muscle…Some countries, like Denmark, have advocated eliminating the strain, but considering Belgian Blue is for meat what the Holstein breed is for milk, I doubt breeders will stop raising these animal bodybuilders anytime soon.

Japanese Researchers Create Tweeting Mouse

In a genetically engineered experiment, Japanese scientists at the University of Osaka have created a mouse that tweets like a bird. After crossbreeding genetically altered mice for some time, to see what would happen, they apparently got their first interesting result, by mistake. Researcher Arikuni Uchimura said they were expecting physical mutations, but definitely not a tweeting mouse.

The “mistake” happened at the University of Osaka called “Evolved Mouse Project”, where scientists have the sole purpose of breeding mice ‘pron to miscopying DNA and thus to mutation”, without knowing for sure what will the end results may be.
