British lawmakers in the House of Commons voted Tuesday to allow scientists to create babies from the DNA of three people — a move that could prevent some children from inheriting potentially fatal diseases from their mothers. The vote in the House of Commons was 382-128 in favor. The bill must next be approved by the House of Lords before…
There are 3 billion letters in the human genome, and scientists have endlessly debated how many of them serve a functional purpose. There are those letters that encode genes, our hereditary information, and those that provide instructions about how cells can use the genes. But those sequences are written with a comparative few of the vast number of DNA letters.…
Rapid progress in genetics is making “designer babies” more likely and society needs to be prepared, leading scientists have told the BBC. Dr Tony Perry, a pioneer in cloning, has announced precise DNA editing at the moment of conception in mice. In the journal Scientific Reports, he details precisely editing the genome of mice at the point DNA from the…
A study of twins conducted by Stanford University School of Medicine investigators shows that our environment, more than our heredity, plays the starring role in determining the state of our immune system, the body’s primary defense against disease. This is especially true as we age, the study indicates. Much has been made of the role genes play in human health.…
Research by UCLA life scientists and 50 colleagues sheds new light on the biological differences among more than 150 species of monkeys in South America, many of which are endangered. Their findings could be particularly important in shaping efforts to conserve the biodiversity of primates in South America. The scientists have resolved a dispute over whether a small population of…
In the United States, almost no one can trace their ancestry back to just one place. And for many, the past may hold some surprises, according to a new study. Researchers have found that a significant percentage of African-Americans, European Americans, and Latinos carry ancestry from outside their self-identified ethnicity. The average African-American genome, for example, is nearly a quarter…
