Ingredient in Indian Long Pepper Shows Promise Against Brain Cancer in Animal Models

Penn scientists use cryo-electron microscopy to illuminate how piperlongumine works against glioblastoma. Piperlongumine, a chemical compound found in the Indian Long Pepper plant (Piper longum), is known to kill cancerous cells in many tumor types, including brain tumors. Now an international team including researchers from the Perelman School of Medicine at the University of Pennsylvania...

How one SARS-CoV-2 protein keeps cells from fighting back

New research has uncovered a way SARS coronaviruses delay an immune defence against them. The coronavirus responsible for the SARS outbreak of 2003 and the one causing the current pandemic may prevent cells from responding to infection in a similar manner. They do this by making a viral protein that keeps molecules from moving through pores in...

Study reveals the gateway to conscious awareness

MICHIGAN MEDICINE – UNIVERSITY OF MICHIGAN During our waking hours, the brain is receiving a near-constant influx of sensory signals of various strengths. For decades, scientists have wondered why some signals rise to the light of conscious awareness while other signals of a similar strength remain in the dark shadows of unconsciousness. What controls the...
