Telomeres Might Predict Lung Cancer Recurrence
Telomeres are sections of DNA that tell an interesting story about lifespan. Shorter telomeres usually suggest a shorter life -- but new research by a Wilmot lung cancer expert shows that longer telomeres might be a promising biomarker for a recurrence of early stage lung cancer.
Astrocytes – cells that until only recently have been dismissed as merely brain “glue” – are becoming increasingly important and flexible tools in confronting a range of neurological disorders. New research shows that the right kind of astrocyte can restore order and rescue cells in brains ravaged by Parkinson’s disease.

At the end of each year, the editors of Science magazine sift through the previous 12 months of research and select ten “breakthroughs” that signify seminal scientific achievements. This year’s list includes a study by URMC neuroscientists that reveals that the brain cleans itself while we sleep.

More and more people with HIV are reaching their 50s and beyond thanks to advances in anti-retroviral therapies. That is good news. However, one of the long term impacts of living with the disease is a heightened risk of cognitive problems, such as dementia and functional decline.

When James Parkinson published an essay in 1817 describing the condition that would eventually bear his name, his findings were formulated – in great part – by watching people walk the streets and parks near his home in London. Flash forward some 200 years and this basic principal of observation could enable neurologists to provide care directly to Parkinson’s patients who are sitting in their own living rooms thousands of miles away.

Individuals with impaired liver function are unable to remove ammonia – a by-product of normal cellular activity – from their bodies fast enough. This result is a host of neurological problems, including seizures, for which doctors have no effective treatment. A new study shows that an existing blood pressure drug may be able to prevent the molecular chain reaction in the brain triggered by ammonia.
