The breast cancer screening guidelines proposed yesterday by the United States Preventive Services Task Force (USPSTF) would result in thousands of additional and unnecessary breast cancer deaths each year, according to radiologists at Loyola University Health System (LUHS).

With a new magnetic resonance imaging (MRI) technique, the vocal neuromuscular movements of singing and speaking can now be captured at 100 frames per second. The sound of the voice is created in the larynx, located in the neck. When we sing or speak, the vocal folds--the two small pieces of tissue--come together and, as air passes over them, they vibrate, which produces sound. After 10 years of working as a professional singer in Chicago choruses, a researcher's passion for vocal performance stemmed into study to understand the voice and its neuromuscular system, with a particular interest in the aging voice.

Developing technology is on track to predict if and when breast cancer will appear. "We're creating a breast cancer risk analysis system," said an electrical engineer on the study. "It will be able to inform doctors about the patient's risk of developing cancer within a few years."

The brains of babies 'light up' in a very similar way to adults when exposed to the same painful stimulus, a pioneering brain scanning study has discovered. It suggests that babies experience pain much like adults. As recently as the 1980s it was common practice for babies to be given neuromuscular blocks but no pain relief medication during surgery. In 2014 a review of neonatal pain management practice in intensive care highlighted that although such infants experience an average of 11 painful procedures per day 60% of babies do not receive any kind of pain medication.

A novel approach that allows real-time imaging of the immune system's response to the presence of tumors -- without the need for blood draws or invasive biopsies -- offers a potential breakthrough both in diagnostics and in the ability to monitor efficacy of cancer therapies.

A new diagnostic method, namely spectral histopathology, facilitates marker-free detection of individual subtypes of lung cancers. It is an automatable imaging process which, by classifying specific forms of lung cancer, facilitates a prognosis regarding a tumor's aggressiveness. The team compares the results of traditional diagnostic procedures with those of spectral histopathology in a new article.

Researchers have demonstrated the most precise method yet to measure the structural configuration of monoclonal antibodies (mAbs), an important factor in determining the safety and efficacy of these biomolecules as medicines. Monoclonal antibodies are proteins manufactured in the laboratory that can target specific disease cells or antigens. The method described in a recent paper may soon help manufacturers and regulators better assess and compare the performance and quality of mAbs.
