The origins of flowering plants from peas to oak trees are now in clearer focus. A study appearing online this week in the Proceedings of the National Academy of Sciences unravels 100 million years of evolution through an extensive analysis of plant genomes. It targets one of the major moments in plant evolution, when the ancestors of most of the world’s flowering plants split into two major groups.

Why are Asians drank face is easy to red? Recently, Chinese Academy of Sciences of Kunming Institute of Zoology research team led by Bing Su published research papers in the "BMC Evolutionary Biology" , pointed out that "drinking blush" It may be related to rice cultivation. They believe that the era of domesticated crops such as rice in China has led to changes in the structure of human food and then led to a certain gene mutation, making easy for the so-called "Asian red."

Increasing the oil in tobacco plant leaves may be a step towards using the plants for biofuel, The  paper was published online in Plant Biotechnology Journal. Researchers from the Biotechnology Foundation Laboratories at Thomas Jefferson University have identified a way to increase the oil in tobacco plant leaves, which may be the next step in using the plants for biofuel.

From Journal of the American Chemical Society: Singapore are reporting development of a new electronic sensor that shows promise as a faster, less expensive, and more practical alternative than tests now used to detect DNA. Such tests are done for criminal investigation, disease diagnosis, and other purposes. The new lab-on-a-chip test could lead to wider, more convenient use of DNA testing, the researchers say. Their study is scheduled for the Sept. 2 issue of the Journal of the American Chemical Society, a weekly publication.

A long-standing mystery surrounding a fundamental process in plant biology has been solved by a team of scientists at the University of California, Davis. The group’s groundbreaking discovery that a plant hormone called auxin is responsible for egg production has several major implications.

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.

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.

“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.

A genetic study of Africa suggests that the origin of humanity lies in a sandy, inhospitable region near the coastal border of Namibia and Angola. The Bushmen, or San people, who populated in the area may be the closest thing to a biblical Adam and Eve. The research paper published in 《Science》journal.

A way to save time, money and frustration in searches for specific genes have been found by researchers at Purdue University, It can shed light on the biological processes associated with all forms of life. The work finished by Andrew DeWoody, a professor of genetics, and postdoctoral associate Matthew C. Hale, they have provided evidence that a step called normalization is no longer necessary with recent advances in DNA sequencing technology. Instead, they used a theoretical approach called rarefaction for gene discovery, a process developed for ecological surveys to determine the abundance of a species in an ecosystem. The results were published in the journal BMC Genomics.
