By tweaking these dual role regions, scientists could develop gene therapy techniques that>
One tenet of natural selection is a random walk of genes but nature may be more predictable than rolls of dice suggest. A new study of the mimicry of several distantly-related South American rainforest butterfly and moth species with similar wing color patterns that may warn away predators (it's not a costumed bluff>
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.

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>

Because fatigue is a non-specific symptom, fibromyalgia becomes a 'diagnosis of exclusion', where pain persists but testable conditions are ruled out. It is>
