Osteoarthritis is the most common degenerative joint disease, affecting 22% of adults over 40 globally. Although the condition has been extensively studied through a medical perspective, the molecular changes associated with osteoarthritis remain unclear. In a new study, researchers have used a combination of techniques to track the progression of the disease and the changes associated with it.

Kenyan patients who spend more than three days in the nation's hospitals are more likely to harbor a form of bacteria resistant to one of the most widely used antibiotic classes, according to a recent study. The research team found that 66% of hospitalized patients were colonized with bacteria resistant to third-generation cephalosporins, compared to 49% among community residents. Third-generation cephalosporins are typically used for serious infections, and resistance to these antibiotics leaves limited options for treating patients with some bacterial infections. The study was part of a pair of projects in Kenya and a third in Guatemala to determine the prevalence of antibiotic-resistant bacteria. The research also aimed to identify risk factors for colonization with bacteria resistant to important and frequently used classes of antibiotics, including third-generation cephalosporins.

A group led by researchers at Nagoya University in Japan used nanowires to develop a technology for capturing cell-free DNA from cancer cells in urine samples. Using their technique, they captured this DNA and successfully detected the IDH1 mutation, a characteristic genetic mutation of brain tumors. Their findings show a safe, effective, and non-invasive way of diagnosing brain tumors.

Fish consumption has long been associated with numerous health benefits. However, it is also the main dietary source of toxic mercury in humans. A year-round study from a boreal lake shows that mercury concentration in some fishes is significantly higher in winter and near spring spawning and lowest in autumn.
