Researchers have discovered several rare types of helper T cells that are associated with immune disorders such as multiple sclerosis, rheumatoid arthritis, and even asthma. The discoveries were made possible by a newly developed technology they call ReapTEC. The new T cell atlas is publicly available and should help in the development of new drug therapies for immune-mediated diseases.

Pseudomonas aeruginosa -- an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions -- evolved rapidly and then spread globally over the last 200 years, probably driven by changes in human behavior, a new study has found.

In 2019, more than 12,000 new cases of cervical cancer were diagnosed and upwards of 4,000 patients died in the U.S. The causal link between human papillomavirus (HPV) infection and the development of cervical cancer is well documented. Cervical cancer screening guidelines are currently in the review process for updates.

Scientists have uncovered a brain circuit in primates that rapidly detects faces. The findings help not only explain how primates sense and recognize faces, but could also have implications for understanding conditions such as autism, where face detection and recognition are often impaired from early childhood.

Oncologists use biopsy and imaging techniques to diagnose and monitor tumor diseases and assess treatment success. Researchers have further developed an advanced method to analyze liquid biopsies of DNA fragments in the blood. The new method is fast and practical, without putting much of a strain on patients. This could make it possible to provide diagnostics and treatments that are more closely tailored to individual patients in the future.
