A recent study has unraveled the intricate cellular blueprint behind the iconic fragrance of Prunus mume flowers. Using state-of-the-art single-cell RNA sequencing, researchers have constructed a high-resolution map of gene expression within petal cells across blooming stages. This atlas not only identifies six key cell types but also pinpoints the genetic pathways responsible for floral scent production. These discoveries mark a significant leap forward in understanding floral scent biosynthesis and could open new doors to cultivating aromatic plant varieties and innovations in the fragrance industry.

Since older adults have been more severely affected by acute COVID-19, researchers have hypothesized that older adults may have worse long COVID symptoms as well. But according to new research published in the Annals of Neurology, an official journal of the American Neurological Association, Northwestern Medicine researchers found on an average of 10 months after COVID-19 onset, younger (ages 18-44) and middle-aged (ages 45-64) adults had worse neurologic symptoms of long COVID than adults 65 and older. Symptoms included headache, numbness and tingling, problems with smell and taste, blurred vision, depression, anxiety, insomnia, fatigue and a decrease in cognitive function. These symptoms occurred regardless of if the patient had mild or severe COVID-19 infections.

Patients with lumbar spinal stenosis, a common cause of lower back pain in older adults, may benefit from minimally invasive lumbar decompression. Patients receiving the procedure reported significant reductions in pain, along with better physical function and no decrease in mobility or quality of life. The investigators鈥� abstract received a Resident/Fellow Travel award from the American Society of Regional Anesthesia and Pain Medicine (ASRA Pain Medicine) and will be presented at the upcoming 23rd Annual Pain Medicine Meeting in Las Vegas, NV.
