Scientists from the Machine Intelligence from Cortical Networks (MICRONS) consortium have published the microconnectome of a cubic millimeter of the mouse brain. This is the most complete map of this organ to date at nanometer resolution for a mammal. It not only contains the structure and connections of each and every cell in that volume of tissue, but is also linked to the neuronal activity of that portion of the CNS, linking anatomy and function in the same cells.

U.K. scientists developed a saliva-based test which better predicts the risk of prostate cancer than current prostate-specific antigen (PSA) blood tests by analyzing DNA to look for genetic variants linked to prostate cancer and calculating a polygenic risk score.

The Trump administration applied a 90-day hold on nation-specific tariffs, but a group of 26 House Democrats urged the administration to think carefully before acting on a threat to impose tariffs on pharmaceuticals.

AI could significantly improve the value of patient recalls following mammography, but so far radiologists seem reluctant to rely on computer-aided readings. Radiologists tend to trust their own judgment – and that of their colleagues – in mammogram readings far more than AI-based diagnostics, even when the AI is much more accurate, a prospective trial analysis published in Radiology by Karolinska Institutet researchers found.

Researchers from the University of Cincinnati filed for protection of an electrochemical aptamer-based biosensor technology with improved sensitivity and longevity, which has the potential for monitoring several biomarkers over sustained periods.
