By using ultrafast laser pulses to slice off pieces of chromosomes and observe how the chromosomes behave, biomedical engineers at the University of Michigan have gained pivotal insights into mitosis, the process of cell division. The findings could help scientists better understand genetic diseases, aging and cancer. 阅读全文 »
As the saying goes, “people in groups”, so we thought that people are more willing to choose their partners with a similar genetic heritage. However, a recent study has shown that: People are more likely to become lovers if their genes share little in common, and to select those people who have different genetic, It can improve the immunity of future generations. A possible biological mechanism controlling the sexual attraction between men and women. 阅读全文 »
“Genetics just got personal. Don’t worry. We’re here to help.” This is a slogan for personal genomics. Over a year ago, Iceland’s deCODE Genetics kicked off a new era in personalised genetics with the launch of a direct to consumer service dubbed deCODEme. And a few days later, California’s 23andMe launched its own service. In November 2008, that company’s service was named Time magazine’s invention of the year. 阅读全文 »

From today, I will collect any references about RNA silencing. RNA silencing is a remarkable type of gene regulation based on sequence-specific targeting and degradation of RNA. The term encompasses related pathways found in a broad range of eukaryotic organisms, including fungi, plants, and animals. In plants, it serves as an antiviral defense, and many plant viruses encode suppressors of silencing. The emerging view is that RNA silencing is part of a sophisticated network of interconnected pathways for cellular defense, RNA surveillance, and development and that it may become a powerful tool to manipulate gene expression experimentally. 阅读全文 »
A man has been shot near a Harvard University dormitory. The man was wounded in his stomach Monday outside an entrance to Kirkland House, one of a dozen dorms on the university’s campus in the Boston suburb of Cambridge. He’s hospitalized in stable condition. 阅读全文 »
