Many human proteins are not as good as they might be because the gene sequences that code for them have a double role which slows down the rate at which they evolve, according to new research published in PLoS Biology.
By tweaking these dual role regions, scientists could develop gene therapy techniques that>
Many people, perhaps most, hate the idea that life might depend on chance processes. It is a human tendency to search for meaning, and what could be more meaningful than the belief that our lives have a greater purpose, that all life in fact is guided by a supreme intelligence which manifests itself even at the level>
The gut bacterium Bacteroides fragilis has long presented researchers with a paradox. It has been associated with colorectal cancer, yet it also lives quite happily in most healthy people. A new study from a Danish research team offers a possible clue. When they looked beyond the bacterium itself and into its genome>

Bacteria attack with toxins designed to hijack or kill host cells but they have ways of protecting themselves from their own toxins. Researchers have described one of these protective mechanisms, potentially paving the way for new classes of antibiotics that cause the bacteria's toxins to turn on themselves>
Older people who eat large amounts of meat have a lower risk of dementia and cognitive decline than they should have with a gene that some link to increased risk. The gene that has been linked to increased risk is Apolipoprotein E, which plays a role in the transport of cholesterol and fats in the brain and blood>
