Health-Care AI Is Here. We Don’t Know if It Actually Helps Patients.
Healthcare providers are rapidly integrating AI tools such as ambient scribes and predictive analytics into clinical workflows. Early studies suggest these systems can reduce clinician burnout and speed up tasks, but researchers like Jenna Wiens and Anna Goldenberg warn that evidence linking AI use to better patient outcomes remains scarce. A recent survey shows roughly 65% of U.S. hospitals employ AI‑assisted predictive tools, yet only two‑thirds evaluate accuracy and even fewer check for bias. The authors urge systematic outcome studies before assuming AI improves care.
No One’s Sure if Synthetic Mirror Life Will Kill Us All
In 2019 a group of synthetic biologists and ethicists convened to explore funding for “mirror” bacteria—microbes built from opposite‑handed proteins, sugars and lipids. By 2024, many participants warned that such organisms could evade natural predators and immune systems, potentially causing...
A Woman’s Uterus Has Been Kept Alive Outside the Body for the First Time
Spanish researchers at the Carlos Simon Foundation have kept a donated human uterus alive outside the body for 24 hours using a normothermic perfusion device called “Mother” (PUPER). The machine circulates oxygenated, nutrient‑rich blood through the organ, mimicking natural circulation. This...
