Fluorescence guidance can enable surgeons to assess cancer tissues in real-time

A clinical research study published in the British Journal of Surgery shows that fluorescence guidance (where a fluorescent chemical compound re-emits light with a long wavelength) can enable a colorectal surgeon to assess cancer tissues visually and with more specificity in real-time during surgery, by utilising near-infrared (NIR) light from an administered fluorophore in conjunction with artificial intelligence (AI) methods.

Non-contact IR thermometers fail for COVID-19 temperature screening, say physicians

While a fever is one of the most common symptoms for people who get sick with COVID-19, taking one's temperature is a poor means of screening who is infected with the SARS-CoV-2 virus that causes the disease, and more importantly, who might be contagious.

Higher risk of West Nile virus infection in low-income urban neighborhoods in Baltimore

In Baltimore, Maryland, people living in low-income urban neighborhoods are more at risk of contracting West Nile virus, a mosquito-borne disease, than people living in more affluent neighborhoods. So reports a new study published in the Journal of Medical Entomology.
