Who is more prone to recurrent UTIs? Bladder bacteria may be key

Researchers identified a strong association between beneficial bacteria and estrogen hormone therapy in postmenopausal women. The study found that estrogen may play a role in reducing susceptibility to recurrent UTIs by promoting the growth of good bacteria such as Lactobacilli in the bladder. Conversely, women with recurrent UTIs had ...

Weedy rice has become herbicide resistant through rapid evolution

Scientists found that weedy rice has developed herbicide resistance through gene flow from crop rice, with most fields showing resistant plants within 20 years of herbicide-resistant rice cultivation. This rapid evolution is due to the close proximity of weedy and crop rice in the same fields, allowing for pollen transfer and outcrossing.
