Researchers from Mass General Brigham developed olfactory tests—in which participants sniff odor labels that have been placed on a card—to assess people’s ability to discriminate, identify and remember odors. They found that participants could successfully take the test at home and that older adults with cognitive impairment scored lower on the test than cognitively normal adults.

Scientists at the UCLA Health Jonsson Comprehensive Cancer Center and the University of Toronto have revealed how a tiny chemical modification in RNA, known as m6A, plays a critical role in the progression of prostate cancer, including driving some of its most dangerous forms of the disease.

Frederic L.W.V.J. Schaper, MD, PhD, director of Epilepsy Network Mapping at the Center for Brain Circuit Therapeutics at Brigham and Women’s Hospital and an instructor of neurology at Harvard Medical School, is the senior author of a paper published in Nature Communications, “A generalized epilepsy network derived from brain abnormalities and deep brain stimulation.”

Dague and her colleagues identified several trends. The most striking is the tendency of former inmates to forsake medication for a chronic condition even with costs covered by Medicaid, the federal-state insurance program for low-income people. The researchers found this trend particularly striking because other studies have shown that Medicaid increases access to healthcare for people who were previously incarcerated. The new study suggests insurance alone may not be enough.
