Highly sensitive DNA nanosensor can accurately detect lethal superbugs

Antibiotics have revolutionized the field of medicine by making it possible to treat most known microbial diseases today. However, their uncontrolled usage has led to the major global problem of antibiotic resistance. As we continue to exploit antibiotics, sometimes at doses much higher than needed, disease-causing bacteria are rapidly evolving defense strategies to evade them. […]

AI screenings of pap smears can detect precursors to cervical cancer

Using artificial intelligence and mobile digital microscopy, researchers hope to create screening tools that can detect precursors to cervical cancer in women in resource-limited settings. A study led by researchers at Karolinska Institutet in Sweden now shows that AI screenings of pap smears carried out with portable scanners were comparable to analyses done by pathologists. […]
